Accepted Answer

What Is the Difference Between Plastic and Metal Eyeglass Frames? The main difference between plastic and metal eyeglass frames is material structure: plastic frames are molded or cut from acetate, TR90, or injected plastic, while metal frames are formed from titanium, stainless steel, or Monel. Plastic frames are lighter in feel, easier to color, and lower in cost. Metal frames are stronger, more adjustable, and better for slim or rimless designs. For B2B buyers, the choice affects price band, target market, and SKU planning. READSUN Optical produces both categories for wholesale and OEM/ODM programs. Plastic vs Metal Eyeglass Frames: Side-by-Side Comparison for B2B Buyers What is the difference between plastic and metal eyeglass frames? Frame material determines weight, durability, adjustability, allergy risk, and price. It also shapes how a collection is positioned in the market. The table below compares plastic eyeglass frames vs metal across the factors that matter most to importers and brands. Factor Plastic Frames Metal Frames Common materials Acetate, TR90, Ultem, Optyl, injection plastic Titanium, beta titanium, stainless steel, Monel Weight Light to medium Light to medium (titanium is lightest) Durability Good; acetate can be polished and repaired High; metal holds shape and resists stress Adjustability Limited; requires heat adjustment High; temples and nose pads can be adjusted Allergy risk Low; acetate and TR90 are generally skin-friendly Depends on material; Monel contains nickel Color options Very wide; patterns, transparency, layering Limited; plating and coating colors Design style Bold, fashion-forward, retro Slim, minimalist, professional Price band Low to mid Mid to high Best for Fashion collections, kids, value lines Premium, rimless, functional, Asian fit Plastic acetate eyeglass frames — wide color range, layered patterns, and a fashion-forward look. View our custom optical frames for acetate options. This comparison shows the main differences between plastic and metal eyeglass frames. Buyers should match the material to the target customer, price point, and market positioning. Key Differences Between Plastic and Metal Eyeglass Frames Beyond the table, several practical differences affect sourcing decisions and after-sales performance. Weight, Comfort, and Durability Plastic frames distribute weight differently from metal frames. Acetate frames feel solid but can be heavier in oversized shapes. TR90 and Ultem are lighter and more flexible, which makes them a strong choice for kids and sport frames. Metal frames, especially titanium and beta titanium, offer the best strength-to-weight ratio. They hold their shape under stress and resist bending better than plastic. This is why custom optical frames in metal are often chosen for premium and rimless designs. Adjustability and Fit Metal frames are easier to adjust. Temples can be bent, nose pads can be repositioned, and the frame can be reshaped to fit different face types. Plastic frames require heat adjustment and have less range. For markets with diverse face shapes or low nose bridges, metal frames with adjustable nose pads are often the better choice. Allergy Risk and Skin Compatibility Acetate and TR90 are generally skin-friendly. Metal frames vary: titanium and stainless steel have low nickel release, while Monel contains nickel and may cause reactions in sensitive customers. Buyers sourcing for EU or allergy-sensitive markets should request nickel release testing. READSUN supports compliance documentation through our Manufacturing Excellence process. Customization, Colors, and MOQ Plastic frames offer more color freedom. Acetate can be produced in transparent, tortoiseshell, two-tone, and layered patterns. Metal frames are limited to plating and coating colors. For brands building a distinctive look, plastic offers more design range. For brands targeting slim, professional, or functional segments, metal is the better fit. MOQ depends on the material and order model. Stock plastic frames have the lowest MOQ. Custom acetate colors require a higher MOQ because of sheet or block sourcing. Metal frames with custom plating also carry higher MOQ. Buyers can review OEM & ODM eyewear services for full details. Metal titanium eyeglass frames — slim, strong, and highly adjustable. READSUN produces titanium, stainless steel, and Monel frames for wholesale programs. Which Is Better for Your Eyewear Brand: Plastic or Metal Eyeglass Frames? There is no single answer. The right choice depends on your brand positioning, target market, and price band. Common B2B strategies for plastic vs metal eyeglass frames include: Fashion-forward brands: Plastic acetate frames for bold colors and shapes. Premium minimalist brands: Titanium or stainless steel frames for slim, durable designs. Kids and sport lines: TR90 or Ultem plastic frames for flexibility and impact resistance. Value lines: Injection plastic frames for low-cost, high-volume programs. Asian fit markets: Metal frames with adjustable nose pads for better fit. Allergy-sensitive markets: Titanium or acetate frames with low nickel release. Mixed collections: Combine both materials to cover multiple price bands and customer segments. Buyers can review custom optical frames for material options, or learn more about our Manufacturing Excellence for production and quality details. Plastic vs Metal Eyeglass Frames: Specifications B2B Buyers Should Confirm Before approving a quotation or sample, confirm these specifications: Material: acetate, TR90, Ultem, Optyl, titanium, beta titanium, stainless steel, or Monel. Structure: full rim, semi-rimless, or rimless. Weight target: standard or lightweight. Adjustability: fixed or adjustable nose pads and temples. Color and finish: solid, transparent, tortoiseshell, layered, matte, glossy, or plated. Hardware: hinge type, nose pads, and temple tips. Compliance: nickel release testing for metal frames. Packaging: standard export packing or custom branded packaging. Plastic vs Metal Eyeglass Frames: MOQ, Lead Time, and Pricing MOQ, lead time, and pricing depend on the material, structure, and order model. Stock plastic frames have the lowest MOQ and fastest lead time. Metal frames with custom plating or titanium construction increase MOQ and lead time. Full OEM development with new tooling requires the highest MOQ and longest lead time. Typical lead time for stock frames is 7–15 days. ODM orders take 30–45 days after sample approval. Full OEM programs may take 45–75 days. Material also affects cost: acetate, TR90, titanium, and stainless steel have different production processes and price levels.

Question 2

Compare adjustable vs integrated nose pads for eyeglass frames. This B2B guide covers materials, mounting systems, Asian fit sourcing, and MOQ from READSUN Optical.

Accepted Answer

What Are the Different Types of Nose Pads on Eyeglass Frames? The two main types of nose pads on eyeglass frames are adjustable nose pads and integrated nose pads. Adjustable pads sit on metal arms and can be repositioned for a custom fit. Integrated pads are molded directly into the frame front and stay fixed. For B2B buyers, the choice affects comfort, return rate, and market fit — especially for low-bridge and Asian-fit customers. READSUN Optical produces both types across acetate, TR90, titanium, and stainless steel frames. Eyeglass Frame Nose Pads: Definition and Key Features for B2B Buyers What are eyeglass frame nose pads? Nose pads are the small supports that rest on the bridge of the nose and hold the frame in place. They keep the frame from sliding down and distribute weight across the nose. The pad design also affects how the frame fits different face shapes. The table below compares the two main eyeglass frame nose pads configurations used in eyewear production. Feature Adjustable Nose Pads Integrated Nose Pads Frame type Metal, titanium, stainless steel Acetate, TR90, injection Fit range High — repositionable Low — fixed at production Maintenance Screws, pad replacement No moving parts Appearance Classic, technical Seamless, fashion-forward Best for Asian fit, low bridge, optical stores with fitting service Entry-level, fashion collections, low-maintenance end users Eyeglass frames with adjustable nose pads — repositionable for a custom fit. View our custom optical frames for pad options. Adjustable Nose Pads Adjustable nose pads are mounted on thin metal arms and can be bent or repositioned. They are standard on titanium, stainless steel, and alloy frames. For optical retailers offering professional fitting, adjustable pads accommodate a wider range of nose bridge heights and face shapes. This is a key factor in reducing post-sale fitting complaints. For B2B buyers sourcing custom optical frames, adjustable pads are the recommended choice for markets with diverse face shapes. Integrated Nose Pads Integrated nose pads are molded directly into the frame front. They have no moving parts and offer a clean, seamless look. You will find them most often on acetate, TR90, and injection-molded frames. Maintenance is minimal — no screws to tighten or pads to replace. The trade-off is zero adjustability: once the frame leaves the factory, the pad position is fixed. Eyeglass Frame Nose Pads: Key Facts for Importers and Brands For importers and brands, nose pad selection affects comfort, return rate, and market fit. The table below summarizes the key factors buyers should confirm. Factor What to check Why it matters Pad type Adjustable or integrated Affects fit range and maintenance Pad material Silicone, PVC, or coated titanium Affects comfort, allergy risk, and durability Mounting system Screw-in, push-in, or slide-on Determines replacement compatibility Pad height Standard or Asian fit (2–4 mm higher) Critical for low-bridge markets Color match Transparent or frame-matched Affects visual consistency Compliance Nickel release testing for metal arms Required for EU and other regulated markets One important point is that nose pads for glasses are not interchangeable across mounting systems. A screw-in pad will not fit a push-in arm. Buyers should confirm the mounting system before ordering replacement pads or specifying new frames. Another key point is eyeglass frames with adjustable nose pads are essential for Asian fit markets. Standard "global fit" frames often slip or pinch because the nose bridge is lower. Adjustable silicone pads on extended metal arms — typically positioned 2–4 mm higher than standard — lift the frame off the cheeks and keep lenses away from eyelashes. Silicone nose pads for glasses — soft, non-slip, and skin-friendly. READSUN supports pad customization within OEM & ODM eyewear services. Eyeglass Frame Nose Pads for Wholesale and Custom Programs For wholesale and custom programs, nose pad selection should match the frame material, target market, and durability target. Buyers can choose from stock pad options or develop custom specifications through OEM. Common strategies for eyeglass frame nose pads in B2B programs include: Value lines: Standard integrated pads for low-cost frames. Comfort lines: Adjustable silicone pads for wide-face fit. Asian fit lines: Elevated adjustable pads for low-bridge markets. Premium lines: Coated titanium inserts for allergy-sensitive customers. Acetate frames: Integrated pads with smooth polishing. Metal frames: Adjustable pads with secure screw mounting. Kids frames: Soft silicone pads for comfort and safety. Buyers can review custom optical frames for pad options, or learn more about our Manufacturing Excellence for production and quality details. Eyeglass Frame Nose Pads: Specifications B2B Buyers Should Confirm Before approving a quotation or sample, confirm these specifications: Pad type: adjustable or integrated. Pad material: silicone, PVC, or coated titanium. Mounting system: screw-in, push-in, or slide-on. Pad height: standard or Asian fit. Color: transparent or frame-matched. Compliance: nickel release testing for metal arms. Packaging: standard export packing or custom branded packaging. Eyeglass Frame Nose Pads: MOQ, Lead Time, and Pricing MOQ, lead time, and pricing depend on the pad type, material, and order model. Integrated pads have the lowest MOQ and fastest lead time because they are part of the frame mold. Adjustable pads increase MOQ and lead time slightly because of additional components and assembly steps. Typical lead time for stock frames with integrated pads is 7–15 days. ODM orders with adjustable pads take 30–45 days after sample approval. Full OEM programs may take 45–75 days. Custom pad development adds 3–7 days to the production schedule.

Question 3

Adjustable nose pads vs. integrated nose pads: which is right for your optical frame collection? This B2B guide breaks down comfort, fit, and sourcing considerations.

Accepted Answer

What Are the Different Types of Nose Pads on Eyeglass Frames? Eyeglass frames typically use two nose pad types: adjustable nose pads (metal arms, repositionable) and integrated nose pads (molded into the frame, fixed). For B2B buyers, the choice directly affects comfort, return rates, and market fit — especially for low-bridge and Asian-fit customers. Nose Pads for Glasses: The Two Main Types Nose pads are the small supports that rest on the nose bridge and keep frames from sliding down. Across the wholesale eyewear market, they fall into two configurations. Elegant magenta cat-eye frame from READSUN — equipped with medical-grade adjustable nose pads for a personalized, non-slip fit. View this product page. Adjustable Nose Pads Mounted on thin metal arms, these pads can be bent and repositioned. They are standard on titanium, stainless steel, and alloy frames. For optical retailers offering professional fitting, adjustable pads accommodate a wider range of nose bridge heights and face shapes — a key factor in reducing post-sale fitting complaints. Integrated Nose Pads Molded directly into the frame front, these pads have no moving parts and offer a clean, seamless look. You will find them most often on acetate, TR90, and injection-molded frames. Maintenance is minimal — no screws to tighten or pads to replace. The trade-off is zero adjustability: once the frame leaves the factory, the pad position is fixed. Adjustable vs Integrated Nose Pads: Side-by-Side Comparison for B2B Buyers Feature Adjustable Nose Pads Integrated Nose Pads Frame type Metal, titanium, stainless steel Acetate, TR90, injection Fit range High — repositionable Low — fixed at production Maintenance Screws, pad replacement No moving parts Appearance Classic, technical Seamless, fashion-forward Best for Asian fit, low bridge, optical stores with fitting service Entry-level, fashion collections, low-maintenance end users Why Asian Fit Frames Rely on Adjustable Nose Pads Over 60% of the world’s population has Asian facial features. Standard “global fit” frames often slip or pinch because the nose bridge is lower. Asian fit frames solve this with elevated nose pads and wider bridges (17–20 mm vs. 14–16 mm standard). Adjustable silicone nose pads on extended metal arms — typically positioned 2–4 mm higher than standard — lift the frame off the cheeks and keep lenses away from eyelashes. For B2B buyers sourcing for Asian markets, specifying adjustable nose pads is one of the most practical ways to reduce returns. If you are developing a collection for these markets, view our custom optical frames or explore OEM & ODM eyewear services. Nose Pad Materials: Silicone, PVC, and Titanium Inserts Custom logo metal optical frame with magnetic clip-on — featuring adjustable nose pads for comfort and reinforced hinges for long-term durability. View this product page. Material choice matters as much as pad type. Medical-grade silicone has become the premium standard: soft, flexible, and naturally cushioning. For prescription wearers who wear frames eight or more hours a day, silicone distributes pressure better than rigid PVC and consistently reduces nose fatigue. Coated titanium inserts are another option for buyers targeting customers with a history of reacting to metal hardware. Note: titanium lowers risk but does not eliminate it — parts described as titanium are sometimes alloys or plated components. B2B Sourcing Considerations for Nose Pads Mounting Systems Are Not Interchangeable Before ordering, identify the mount: screw-in, push-in (snap-on), or slide-on. A mismatched mount means the pad will not fit the frame arm. For custom eyeglass frame manufacturing, READSUN can specify the mount system during development to match your collection’s frame architecture. Nose Pad Customization at READSUN READSUN supports nose pad customization within OEM & ODM optical frame projects: adjustable or integrated configuration, silicone or coated titanium materials, and pad height adjustments for Asian fit markets.

Question 4

Main hinge types are standard, spring, barrel, hidden, integrated, and flex. Spring and barrel hinges are most durable. Hinges are the top failure point.

Accepted Answer

What Are the Different Eyeglass Frame Hinge Types? The main eyeglass frame hinge types are standard hinges, spring hinges, barrel hinges, and hidden or integrated hinges. Hinges are the most common failure point on any frame, so choosing the right type affects durability, comfort, repair rate, and after-sales cost. Spring and barrel hinges usually last longer than basic standard hinges. READSUN Optical produces all major hinge types for wholesale, private label, and OEM/ODM programs. Eyeglass Frame Hinge Types: A Plain-English Explanation for B2B Buyers What are eyeglass frame hinge types? A hinge is the joint that connects the frame front to the temple and allows the temple to fold. The hinge design determines how the frame opens and closes, how well it handles stress, and how easy it is to repair. Metal spring hinge optical frame from READSUN — spring hinges allow the temple to flex outward for a more comfortable fit. View this product page. The table below compares the main types of glasses hinges used in eyewear production. Hinge type How it works Durability Best for Standard hinge Simple joint with screw and barrel; folds inward only Basic Value frames, low-cost lines Spring hinge Contains a spring that lets the temple flex outward High Comfort frames, kids, sport, wide faces Barrel hinge Multi-barrel joint with interlocking segments; more barrels = more durability High Premium metal, acetate, durable frames Hidden hinge Integrated into the frame front; not visible from the outside Medium to high Premium slim, minimalist, rimless frames Integrated hinge Molded or cut directly into the frame material Medium TR90, Ultem, and injection plastic frames Flex hinge Flexible metal or polymer section that bends High Sport, kids, flexible frames This comparison shows the main eyeglass frame hinge options in eyewear production. Buyers should match the hinge type to the frame material, target market, and durability target. Eyeglass Frame Hinge Types: Key Facts B2B Buyers Should Check For importers and brands, hinge selection affects durability, return rate, and after-sales cost. The table below summarizes the key factors buyers should confirm. Factor What to check Why it matters Hinge type Standard, spring, barrel, hidden, or integrated Affects durability, comfort, and repair rate Hinge material Stainless steel, nickel silver, titanium, or brass Affects strength, corrosion resistance, and allergy risk Screw type Size, material, and thread design Loose or stripped screws cause hinge failure Weld strength For metal frames, weld quality at the hinge joint Weak welds break under stress Insert depth For acetate frames, how deep the hinge is embedded Shallow inserts pull out under load Fatigue testing Open-close cycle test results Shows real durability performance Corrosion resistance Salt spray test and plating specification Prevents rust and plating failure Compliance Nickel release testing for metal hinges Required for EU and other regulated markets The term optical frame hinges covers all hinge types used in eyewear. The most common failure point is not the hinge body itself but the screw, the weld, or the insert. Buyers should confirm screw quality, weld strength, and insert depth, not just the hinge type. Another key point is optical frame barrel hinge design. Barrel hinges use interlocking segments that distribute stress more evenly than a simple standard hinge. This makes them more durable, especially in metal frames and premium acetate frames. Barrel hinges are also easier to adjust and repair. Hinge Durability Testing: What Buyers Should Request Hinge fatigue testing opens and closes the hinge for thousands of cycles and records any failure. At READSUN, we use stable hinge integration with automated drilling and precision pinning to ensure smooth hinge movement and long-term structural integrity. We also conduct hinge functional testing during the prototyping stage to validate durability before mass production. Buyers should request fatigue test results for every hinge type they plan to order. Eyeglass Frame Hinge Types for Wholesale and Custom Programs For wholesale and custom programs, hinge selection should match the frame material, target market, and durability target. Buyers can choose from stock hinge options or develop custom hinge specifications through OEM. Custom men optical frame from READSUN — reinforced five-barrel stainless steel hinges provide firm, smooth opening and closing. View this product page. Common strategies for eyeglass frame hinge types in B2B programs include: Value lines: Standard hinges with quality screws for basic durability.

Rimless frames: Hidden or integrated hinges for a minimal look. Buyers can review custom optical frames for hinge options, or learn more about our Manufacturing Excellence for production and quality details. Eyeglass Frame Hinge Types: Specifications B2B Buyers Should Confirm Before approving a quotation or sample, confirm these specifications: Hinge type: standard, spring, barrel, hidden, integrated, or flex. Hinge material: stainless steel, nickel silver, titanium, or brass. Screw type: size, material, and thread design. Weld strength: for metal frames, weld quality at the hinge joint. Insert depth: for acetate frames, how deep the hinge is embedded. Fatigue testing: open-close cycle test results. Corrosion resistance: salt spray test and plating specification. Compliance: nickel release testing for metal hinges. Packaging: standard export packing or custom branded packaging. Eyeglass Frame Hinge Types: MOQ, Lead Time, and Pricing MOQ, lead time, and pricing depend on the hinge type, material, and order model. Standard hinges have the lowest MOQ and fastest lead time. Spring and barrel hinges increase MOQ and lead time because of additional components and assembly steps. Hidden and integrated hinges add tooling complexity. Typical lead time for stock frames with standard hinges is 7–15 days. ODM orders take 30–45 days after sample approval. Full OEM programs may take 45–75 days. Hinge fatigue testing adds 3–7 days to the production schedule. For an accurate quotation, share your target hinge type, material, frame structure, quantity, logo, packaging, and destination market.

The main hinge types are standard hinges, spring hinges, barrel hinges, hidden hinges, integrated hinges, and flex hinges. Each type offers different durability, comfort, and repair characteristics. What are glasses frame hinge types? Glasses frame hinge types include standard, spring, barrel, hidden, integrated, and flex hinges. Standard hinges are the simplest. Spring and barrel hinges are more durable. What are the types of glasses hinges? The common types are standard, spring, barrel, hidden, integrated, and flex hinges. The choice depends on the frame material, target market, and durability target. What is a barrel hinge on glasses? A barrel hinge is a multi-segment joint with interlocking barrels. It distributes stress more evenly than a standard hinge, making it more durable and easier to adjust. The more barrels used, the higher the durability. What is a spring hinge on glasses? A spring hinge contains a spring that lets the temple flex outward. It improves comfort, fits wider faces, and reduces breakage from accidental pulling. What is a hidden hinge on glasses? A hidden hinge is integrated into the frame front and is not visible from the outside. It is used in premium slim, minimalist, and rimless frames. Which hinge type is most durable? Spring, barrel, and flex hinges are the most durable. Standard hinges are the least durable but also the least expensive. Durability also depends on hinge material, screw quality, and weld strength. Barrel hinges with more segments (e.g., five-barrel or seven-barrel) generally outperform simpler designs. How do I test hinge durability? Request hinge fatigue test results. The test opens and closes the hinge for thousands of cycles and records any failure. READSUN provides fatigue testing for every hinge type through our prototype and sample development process. Can READSUN produce frames with custom hinges? Yes. READSUN supports standard, spring, barrel, hidden, integrated, and flex hinge options, plus custom hinge development through OEM.

Question 5

Main eyeglass frame shapes include round, square, rectangle, oval, cat-eye, aviator, browline, geometric, and panto. Shape drives style and market fit.

Accepted Answer

What Are the Different Eyeglass Frame Shapes? The main eyeglass frame shapes are round, square, rectangle, oval, cat-eye, aviator, browline, geometric, panto, and oversized. Each shape creates a different style and suits different face types and customer segments. For B2B buyers, shape is one of the fastest ways to build a collection because it affects style positioning, market demand, and SKU planning. READSUN Optical produces all major frame shapes in acetate, TR90, titanium, and stainless steel for wholesale and OEM/ODM programs. Eyeglass Frame Shapes: Definition and Key Features for B2B Buyers What are the different eyeglass frame shapes? Frame shape refers to the outline of the lens rim and the overall silhouette of the frame front. It is one of the three main ways to classify frames, alongside structure (full rim, semi-rimless, rimless) and material (acetate, TR90, titanium, stainless steel). Square acetate optical frame from READSUN — architectural silhouette with reinforced 5-barrel hinges. View this product page. The table below lists the common eyeglass frame shapes names and their key style features. Shape Key features Typical market Round Circular lens rim; vintage and artistic look Fashion, creative, young adult Square Angular corners; structured and modern Professional, unisex, office wear Rectangle Wider than tall; classic and versatile Value lines, family collections Oval Soft curved rim; gentle and balanced Mid-market, mature customers Cat-eye Uplifted outer corners; feminine and bold Women's fashion, premium Aviator Tear-drop shape; classic and rugged Sunglasses, men's, unisex Browline Thicker top rim; retro and intellectual Vintage, professional, premium Geometric Hexagon, octagon, or angular shapes Design-led, fashion-forward Panto Rounded top, flatter bottom; vintage Retro, classic, unisex Wide / oversized Large lens area; bold statement Fashion, women's, statement lines This table shows the main optical frame shapes used in B2B eyewear collections. Buyers can combine shapes with materials and colors to build a full range that covers different customer segments. Eyeglass Frame Shapes: Key Facts for Importers and Brands For importers and brands, glasses frame shapes list planning is a core part of collection building. Shape affects style positioning, target customer, and sales performance. The table below summarizes the key factors buyers should confirm. Factor What to check Why it matters Target customer Age, gender, style preference Shape should match the customer's style expectations Market trend Current shape trends by region and season Shape trends change faster than material trends Material pairing Acetate, TR90, titanium, or stainless steel Some shapes work better in certain materials Size range Lens width, bridge, temple, and frame width Shape must fit the target market's face sizes Color options Solid, transparent, tortoiseshell, two-tone Color affects how the shape is perceived Structure Full rim, semi-rimless, or rimless Structure can change the visual weight of a shape SKU planning How many shapes per collection Too many shapes can increase inventory risk MOQ Per shape, material, and color Custom shapes require higher MOQ than stock shapes One important point is that shape trends change quickly. A shape that is popular this season may lose demand next season. Buyers should combine trend research with real sales data and customer feedback. The optical frame shapes that sell best are usually the ones that match the local market's style preferences and face sizes. Another point is that shape and face type go together, but B2B content should avoid oversimplified face-shape recommendations. Instead, buyers should focus on market demand and size ranges. A shape that works in one region may not sell well in another, even if it suits the same face type. Shape and Material Pairing: What Works Best Not every shape performs equally well in every material. Based on READSUN's production experience across acetate and metal frame materials, here is a practical pairing guide: Shape Best material pairing Why Square / Rectangle Acetate, titanium Acetate holds sharp architectural edges; titanium keeps it lightweight Round / Panto Acetate, titanium, stainless steel Classic pairing; acetate for vintage feel, metal for minimalist look Cat-eye Acetate Acetate supports the complex curves and color depth needed Aviator Titanium, stainless steel Double-bridge and thin rims work best in metal Geometric / Octagonal Titanium, stainless steel Precision metal cutting holds sharp angles better than acetate Oversized Acetate Acetate provides the structural rigidity needed for large lens areas Browline Acetate + metal combo Mixed materials create the classic browline contrast 2026 Frame Shape Trends: What B2B Buyers Should Know Geometric shapes — hexagons, octagons, and angular designs — now account for roughly 15% of new frame launches in 2026, up from under 5% in 2022. For B2B buyers, geometric frames offer the highest design differentiation. READSUN's octagonal titanium optical frame collection reflects this trend with precision-cut geometries in pure titanium. Meanwhile, minimalist ovals, rectangles, and classic rounds remain high-turnover staples for value and mid-market collections. Custom and Wholesale Eyeglass Frame Shapes at READSUN READSUN Optical supports both stock and custom eyeglass frame shapes programs.

Question 6

Hypoallergenic eyeglass frames reduce skin reactions by using nickel-free materials like titanium, acetate, TR90, Ultem, Optyl, or nickel-free plated steel.

Accepted Answer

What are hypoallergenic eyeglass frames? What are hypoallergenic eyeglass frames? Hypoallergenic eyeglass frames are frames designed to minimize or eliminate allergic skin reactions. They are made from materials that contain little or no nickel, or from metal frames with nickel-free plating. Common hypoallergenic options include titanium, beta titanium, acetate, Optyl, TR90, Ultem, and 316L stainless steel with nickel-free plating. For B2B buyers, hypoallergenic frames are essential for sensitive-skin markets and regulated regions such as the EU. READSUN Optical produces hypoallergenic eyeglass frames with full nickel release testing for wholesale and OEM/ODM programs. Eyeglass Frames Explained for Eyewear Brands and Importers What are hypoallergenic eyeglass frames? They are frames that reduce the risk of contact dermatitis, the most common skin reaction caused by eyewear. Nickel is the leading trigger, followed by cobalt, chromium, and certain rubber or silicone compounds used in nose pads. Hypoallergenic frames solve this problem in two ways: by using a base material that contains no nickel, or by applying a plating system that blocks nickel release. The table below shows the main hypoallergenic material options. Material Nickel content Allergy risk Best for Titanium None Very low; naturally hypoallergenic Premium, sensitive-skin markets Beta titanium None Very low; naturally hypoallergenic Thin, flexible premium frames Cellulose acetate None Very low Fashion optical, private label Optyl None Very low; no plasticizer leaching Medical and reader frames TR90 None Very low Sport, kids, value lines Ultem None Very low Premium slim frames 316L stainless steel with nickel-free plating Base contains nickel; plating blocks release Low when plating is intact Mid-market metal frames This table shows that hypoallergenic glasses frames can be made from a range of materials. Plastic frames such as acetate, TR90, Ultem, and Optyl are naturally nickel-free. Metal frames require either a nickel-free base or a proper plating system. The safest metal options are titanium and beta titanium, which contain no nickel at all. Eyeglass Frames: What B2B Buyers Should Check For importers and brands, hypoallergenic frames are both a product feature and a compliance requirement. The table below summarizes the key factors buyers should confirm. Factor What to check Why it matters Base material Titanium, acetate, TR90, Ultem, or Optyl Zero nickel content; no allergy risk from the base Plating system Nickel-free plating for metal frames Blocks nickel release from the base metal Plating thickness Thicker layers for durability Thin plating can wear through and expose nickel Nickel release test EN 16128 or REACH-compliant test report Required for EU and other regulated markets Metal parts Hinges, nose pad arms, screws, and temple cores These parts contact skin and must also pass Nose pads Medical-grade silicone or acetate Rubber and silicone can also trigger reactions Dyes and finishes Unpainted or skin-safe finishes Some dyes and coatings can cause irritation Compliance documents Material declaration, test reports, conformity Supports customs and market entry MOQ Per model, material, and plating Hypoallergenic plating and testing add cost The question best hypoallergenic eyeglass frames often comes down to material choice. Titanium and beta titanium are the safest because they contain no nickel. For mid-market price points, 316L stainless steel with nickel-free plating is a good balance of cost and performance. For fashion and value lines, hypoallergenic plastic eyeglass frames such as acetate and TR90 are naturally nickel-free. Another important point is that allergy risk is not only about the frame front. Hinges, nose pad arms, screws, and temple cores also contact the skin. All metal parts must meet the same nickel release limits. Buyers should request a full nickel release test report for the complete frame, not just the front. Custom and Wholesale Eyeglass Frames at READSUN READSUN Optical supports both stock and custom hypoallergenic eyeglass frames programs.

Question 7

Nickel-free frames use titanium, acetate, TR90, Ultem, or nickel-free plated steel to prevent skin reactions. EU REACH limits nickel release to 0.5 µg/cm²/week.

Accepted Answer

What are nickel-free eyeglass frames? Nickel-free eyeglass frames are frames made from materials that contain little or no nickel, or frames that are plated with a nickel-free barrier system. They are designed for people with nickel sensitivity, a common cause of skin irritation from metal eyewear. Common nickel-free options include titanium, beta titanium, 316L stainless steel with nickel-free plating, acetate, TR90, Ultem, and Optyl. READSUN Optical produces nickel-free frames with full nickel release testing for wholesale and OEM/ODM programs. Nickel Free Eyeglass Frames: Definition and Key Features for B2B Buyers What are nickel-free eyeglass frames? They are frames designed to keep nickel release below the limit that triggers skin reactions. This can be achieved in two ways: using a base material that contains no nickel, or using a base material with a plating system that blocks nickel release. Nickel is the most common cause of contact allergy worldwide. For markets such as the EU, nickel release is regulated by REACH, which limits nickel release to 0.5 µg/cm²/week for items in prolonged skin contact. This is why nickel free optical frames are in demand from importers, optical chains, and brands targeting sensitive-skin customers.

Question 8

Stainless steel frames are hypoallergenic when made from 316L or 304 steel with nickel-free plating. Nickel release below 0.5 µg/cm²/week per EU REACH is essential.

Accepted Answer

Are stainless steel eyeglass frames hypoallergenic? Yes, stainless steel eyeglass frames can be hypoallergenic, especially when made from 316L or 304 medical-grade stainless steel with nickel-free plating. Stainless steel itself contains some nickel, but the release rate is very low when the material grade and plating are correct. For sensitive-skin markets, buyers should always confirm nickel release testing per EN 16128 or REACH. READSUN Optical produces stainless steel frames with low nickel release and full test documentation for wholesale and OEM/ODM programs. Stainless Steel Frames: What B2B Buyers Need to Know Are stainless steel eyeglass frames hypoallergenic is one of the most common questions from importers targeting Europe, North America, and other sensitive-skin markets. The answer is not a simple yes or no. It depends on the steel grade, the plating, and the nickel release test result. The table below shows the common stainless steel grades used in eyewear and their allergy profile. Grade Nickel content Allergy risk Best for 316L 10–14% Very low with proper plating Premium and sensitive-skin markets 304 8–10.5% Low with proper plating Mid-market metal frames 430 Minimal Very low Value frames; less corrosion-resistant Monel 63–70% High without plating Value frames with strict nickel control The key point is that are stainless steel eyeglass frames hypoallergenic depends on two factors: the steel grade and the surface treatment. 316L stainless steel with a nickel-free plating system is the safest choice for sensitive-skin markets. Requirements and Compliance Points for Stainless Steel Frames For B2B buyers, allergy control is a compliance issue, not just a product feature. The main requirements come from the EU and other regulated markets. EU REACH: Limits nickel release to 0.5 µg/cm²/week for items in prolonged skin contact. EN 16128: The standard test method for nickel release from spectacle frames. Nickel-free plating: Common plating systems include palladium, gold, chrome, and titanium nitride. Plating thickness: Thicker plating reduces nickel release and improves durability. Welding quality: Poor welds expose base metal and increase nickel release. Nose pads and temple tips: These contact the skin directly and must also meet nickel release limits. Test reports: Every batch should be tested, especially for the EU market. A common misunderstanding is that stainless steel frames allergy risk is only about the frame itself. In practice, the metal parts of the frame — hinges, nose pad arms, and screws — also contact the skin and must pass nickel release testing. Stainless Steel Frames: Cost, Compliance, and Lead-Time Impact Improving nickel release performance affects cost and lead time. Higher-grade steel, thicker plating, and full testing add cost. However, they reduce allergy complaints, returns, and regulatory risk. Option Cost impact Lead-time impact Standard stainless steel with basic plating Lowest Fastest 316L with nickel-free plating Medium Standard 316L with thick palladium or gold plating Higher Longer Full batch nickel release testing Adds testing cost Adds 3–7 days For EU and other regulated markets, full batch testing is often required. Buyers should plan for this in the production schedule and budget. Documentation Needed for Stainless Steel Frames For compliance and after-sales protection, buyers should request these documents: Material declaration: Confirms steel grade (316L or 304). Nickel release test report: Per EN 16128 or equivalent. Plating specification: Layers, thickness, and final finish. Durability test report: Hinge fatigue, temple strength, and weld strength. Declaration of conformity: Confirms the product meets the destination market rules. ISO 12870 test report: Spectacle frame standard test results. Certificate of origin: Supports duty and customs planning. These documents support compliance, after-sales claims, and customs clearance. Buyers should verify that the test reports match the actual production batch. Stainless Steel Frames: Cost and Timeline Impact Nickel-free plating and testing add cost, but they also reduce after-sales problems. A buyer who ignores nickel release may face returns, complaints, and market rejection. The cost of a failed batch is much higher than the cost of proper plating and testing. Typical lead time for stainless steel frames with standard plating is 30–45 days after sample approval. Nickel-free plating and full batch testing may add 5–10 days. For premium plating, lead time may extend to 45–60 days.

Question 9

The lightest eyeglass frame materials are beta titanium, pure titanium, and Ultem, followed by TR90 and stainless steel. Rimless designs reduce weight further.

Accepted Answer

What are the lightest eyeglass frame materials? The lightest eyeglass frame materials are beta titanium, pure titanium, and Ultem, followed by TR90 and stainless steel. Acetate is the heaviest of the common materials. Weight depends not only on the material but also on frame structure, wall thickness, and lens size. Rimless and semi-rimless designs are lighter than full rim. For B2B buyers, lightweight frames support comfort positioning, premium pricing, and markets where all-day wear matters. READSUN Optical produces lightweight frames in titanium, beta titanium, Ultem, and TR90 for wholesale and OEM/ODM programs. Lightest Eyeglass Frame Material: A Plain-English Explanation for B2B Buyers What are the lightest eyeglass frames made of? The answer depends on how weight is measured. Some frames are light because of the material. Others are light because of the design. The lightest frames usually combine a lightweight material with a thin or rimless structure. The table below ranks common frame materials from lightest to heaviest, based on typical finished frame weight. Rank Material Typical frame weight Why it is light 1 Beta titanium Very light High strength-to-weight ratio; can be very thin 2 Pure titanium Very light Low density; strong at thin profiles 3 Ultem (PEI) Very light Stiff at very thin walls; no metal hardware needed 4 TR90 Light Low-density thermoplastic; flexible thin design 5 Stainless steel Light to medium Thin metal profile; denser than titanium 6 Monel Medium Metal alloy; denser than stainless steel 7 Optyl Medium Thermoset epoxy; light but denser than Ultem 8 Cellulose acetate Medium to heavy Solid sheet material; thicker walls needed This ranking is a guide, not a rule. A thin acetate frame can be lighter than a thick metal frame. A rimless titanium frame is lighter than a full rim titanium frame. Buyers should always compare the finished frame weight, not just the material name. Lightest Eyeglass Frame Material: Key Facts B2B Buyers Should Check For importers and brands, lightweight frame materials support comfort, premium positioning, and customer satisfaction. However, light weight is not the only factor. Buyers should also confirm durability, fit, and price. The table below summarizes the key checks. Factor What to check Why it matters Finished weight Weight per frame in grams Directly affects comfort and perceived quality Frame structure Full rim, semi-rimless, or rimless Rimless and semi-rimless reduce weight Wall thickness Front and temple thickness Thinner walls reduce weight but may reduce strength Material grade Genuine beta titanium, pure titanium, or Ultem Low-grade substitutes may be heavier or less durable Durability Hinge quality, welding, and stress testing Light weight should not come at the cost of strength Fit and comfort Nose pad and temple fit Light frames still need proper fit for all-day wear Compliance Nickel release for metal parts Required for EU and other regulated markets MOQ Per model and per color Titanium and Ultem require higher MOQ than acetate One important point is that light does not always mean strong. A very thin frame made from a low-grade material can bend or break easily. Buyers should confirm hinge quality, weld strength, and material grade. A reliable factory will provide durability test reports and sample frames for hands-on testing. Another point is that lightweight optical frames are not only for premium markets. TR90 and Ultem frames can support mid-market price points while offering lightweight comfort. This makes them suitable for kids, sport, and long-wear users. Buying Lightest Eyeglass Frame Material Wholesale: What B2B Importers Should Know When sourcing lightest eyeglass frames for wholesale, importers should match the material to the market and price point. Premium markets often want beta titanium or pure titanium. Mid-market markets often prefer Ultem or TR90. Value markets often use TR90 because of its low cost and good performance. Common questions from wholesale buyers include: Which material is lightest? Beta titanium is usually the lightest, followed by pure titanium and Ultem. Is lighter always better? No. Very light frames can feel less solid to some customers. Buyers should test samples. What structure is lightest? Rimless is the lightest, followed by semi-rimless. Full rim is the heaviest. What about durability? Light frames still need strong hinges and good welds. Confirm durability testing. What is the price difference? Titanium and beta titanium cost more than Ultem, TR90, and stainless steel. Can I mix materials in one order? Usually yes, once total quantity meets MOQ. What is the MOQ? Depends on material and order type. Contact us for an exact MOQ. Buyers can review custom optical frames for lightweight options in titanium, beta titanium, Ultem, and TR90. Our team helps match material to market, price point, and durability target.

Question 10

Cellulose acetate is a plant-based plastic made from cotton linters or wood pulp. It offers rich colors, layered transparency, premium feel, and easy repair. Ideal for fashion eyewear.

Accepted Answer

What is cellulose acetate and what are its advantages? Cellulose acetate is a plant-based plastic made from cellulose (usually cotton linters or wood pulp) treated with acetic acid and acetic anhydride. It is the main material used in premium fashion eyewear. Its advantages include rich color depth, layered transparency, smooth polishing, and easy repair. Cellulose acetate frames feel denser and more premium than injection-molded plastic. READSUN Optical produces custom cellulose acetate frames for wholesale and OEM/ODM programs. Cellulose Acetate Frames: Definition and Key Features for B2B Buyers What is cellulose acetate frame material? It is a plastic derived from natural cellulose, chemically modified to be workable and durable. The result is a solid material that can be cut, heated, polished, and assembled into high-end eyewear frames. Unlike injection-molded plastics, cellulose acetate is supplied as solid sheets. Frame makers cut the shape from the sheet, then tumble and polish it. This process gives cellulose acetate frames their distinctive feel: dense, smooth, and slightly heavier than injection plastic, which customers associate with quality. Property Cellulose Acetate Injection-Molded Plastic Base material Plant-based cellulose Petroleum-based resin Production Sheet cutting, CNC, tumbling, polishing Injection molding Feel and density Dense, solid, premium Lighter, thinner feel Color depth Rich, layered, transparent, tortoiseshell Limited; often painted or sprayed Repairability Good; can be polished and reshaped with heat Limited; cannot be polished out Unit cost Higher Lower Best for Fashion optical, premium, private label Value lines, kids, sport, promotional frames The table above shows the core advantages of cellulose acetate frames: richer color, better feel, and the ability to be repaired. These traits support premium pricing and stronger brand positioning. Cellulose Acetate Frames: Key Facts for Importers and Brands For importers and brands, advantages of cellulose acetate frames go beyond appearance. The material also supports design flexibility, easier after-sales service, and higher perceived value. The table below summarizes the key factors buyers should confirm. Factor What to check Why it matters Sheet origin Italian, Japanese, or domestic sheet Affects color depth, strength, and price Sheet grade Standard, premium, or eco bio-based Affects durability, color stability, and cost Sheet thickness Front and temple thickness Thin sheet may crack; thick sheet adds weight Color type Solid, transparent, tortoiseshell, layered Affects style positioning and market demand Polishing level Rough, fine, mirror polish Affects gloss, scratch resistance, and feel Annealing Tumbling time and stress relief Reduces warping and internal cracks Hinge type Standard, spring, barrel, or hidden Affects durability and repair rate Compliance Nickel release, material safety Required for EU and other regulated markets Buyers should also confirm whether the factory uses genuine cellulose acetate sheet or an injection-molded substitute. Some suppliers market standard plastic frames as acetate. Genuine cellulose acetate eyeglasses are cut from solid sheet, not molded. Another key point is that cellulose acetate is available in premium sheet from Italy and Japan. Italian sheet from suppliers such as Mazzucchelli is widely used in luxury eyewear because of its color depth, layered patterns, and consistent quality. Domestic sheet is used for value and mid-market lines. Cellulose Acetate Frames for Wholesale and Custom Programs For wholesale and custom programs, cellulose acetate frames support a wide range of color, shape, and finish options. Buyers can order stock colors or develop custom colors through sheet ordering. Custom colors usually require higher MOQ because the sheet must be produced in a specific run. Common strategies for cellulose acetate eyeglasses in B2B programs include: Fashion optical lines: Layered colors, tortoiseshell, and transparent frames. Premium collections: Italian sheet with mirror polishing and hand finishing. Private label lines: Custom logo, packaging, and color matching.

Question 11

Ultem (PEI) is a high-performance thermoplastic used for ultra-thin, lightweight, heat-resistant eyeglass frames. It holds shape in hot climates and suits premium slim designs.

Accepted Answer

What is ultem and what are ultem frames? Ultem is a high-performance thermoplastic also known as PEI (polyetherimide). It is used in eyewear to make ultra-thin, lightweight, and heat-resistant frames. Ultem frames can be molded into very thin profiles without losing strength, which makes them ideal for premium slim designs and minimalist collections. Unlike acetate, Ultem does not need polishing, and unlike standard plastic, it resists heat and deformation. READSUN Optical produces custom Ultem frames for wholesale and OEM/ODM programs. Ultem Frames: A Plain-English Explanation for B2B Buyers What is Ultem glasses material? Ultem is the brand name for PEI, a thermoplastic developed by SABIC. It belongs to the same high-performance polymer family used in aerospace, medical devices, and automotive parts. In eyewear, Ultem is valued for three main properties: heat resistance, stiffness at thin walls, and dimensional stability. What is Ultem plastic in frame terms? It is an amber-colored resin that can be injection molded into very thin shapes. Frames made from Ultem are typically lighter than acetate and stiffer than TR90. They hold their shape well under heat and do not warp easily in hot climates or inside a car. Property Ultem (PEI) Cellulose Acetate TR90 Base material Polyetherimide (thermoplastic) Plant-based cellulose acetate Thermoplastic polyamide Production Injection molding Sheet cutting and polishing Injection molding Weight Very light Medium Very light Wall thickness Can be very thin Requires thicker walls Medium thickness Heat resistance Excellent; resists warping Low; can warp in heat Moderate Flexibility Stiff but durable Rigid; adjustable with heat High; memory shape return Color range Solid colors, matte and gloss finishes Rich layered, transparent, tortoiseshell Solid colors, matte and gloss Repairability Limited; not easily polished Good; can be polished and heated Limited Unit cost High Medium to high Low to medium Best for Premium slim frames, minimalist designs Fashion optical, premium, private label Sport, kids, active lifestyle, value lines This comparison shows the core positioning of ultem material frames: premium slim designs with high heat resistance. Ultem is not a replacement for acetate or TR90. It is a separate material for a specific design and market need. Ultem Frames: What B2B Buyers Should Check For importers and brands, ultem frames support premium minimalist positioning and durable thin-wall designs. The table below summarizes the key factors buyers should confirm. Factor What to check Why it matters Material grade Genuine Ultem PEI vs generic high-heat plastic Affects heat resistance, stiffness, and price Mold quality Steel mold condition and injection precision Affects surface finish, thin-wall strength, and consistency Wall thickness Front and temple thickness Ultem allows very thin walls; confirm minimum thickness Frame weight Finished weight per frame Affects comfort and premium positioning Hinge type Standard, spring, barrel, or hidden Affects durability and repair rate Color and finish Solid, matte, gloss, two-tone Affects style positioning and market demand Nose pad Integrated, fixed, or adjustable Affects comfort and fit across face shapes Compliance Material safety, nickel release for metal parts Required for EU and other regulated markets MOQ Per model and per color Injection molds raise upfront cost and MOQ Buyers should also confirm whether the factory uses genuine Ultem PEI or a lower-cost high-heat plastic.

Question 12

Monel is a nickel-copper alloy used in value metal frames. It is strong and easy to weld but not hypoallergenic due to high nickel content. Proper plating and EN 16128 testing are essential.

Accepted Answer

What is monel and are monel frames hypoallergenic? Monel is a nickel-copper alloy widely used in lower-cost metal eyewear frames. It is strong, easy to weld, and holds shape well. However, monel contains a high percentage of nickel, so it is not naturally hypoallergenic. Frames made from monel can cause skin reactions in nickel-sensitive wearers unless the surface is properly plated and nickel release is controlled. READSUN Optical produces monel frames with strict nickel release testing and also offers nickel-free alternatives such as titanium and stainless steel. Monel Frames: Definition and Key Features for B2B Buyers What is monel? Monel is a family of nickel-copper alloys. The most common grade in eyewear is Monel 400, which contains roughly 63–70% nickel and 28–34% copper, with small amounts of iron, manganese, and other elements. It was originally developed for marine and chemical equipment because of its corrosion resistance and strength. In eyewear, monel is used for metal frames, temples, bridges, and endpieces. It is popular because it is easy to weld, easy to bend, and holds its shape well during assembly. These properties make it a cost-effective material for mid-market and value metal frames. Property Monel Stainless Steel (316L) Titanium Base material Nickel-copper alloy Steel alloy with chromium and nickel Commercially pure titanium Weight Medium Light to medium Very light Strength High High High Flexibility Medium Low Low to medium Corrosion resistance Good Good Excellent Nickel content High (63–70%) Low release with proper plating None Allergy risk High without plating Low with nickel-free plating Very low; hypoallergenic Welding Easy Easy Difficult; controlled atmosphere Unit cost Low Medium High Best for Value metal frames, budget lines Mid-market metal frames Premium, sensitive-skin markets This comparison shows the core issue: monel is cost-effective and easy to work with, but its high nickel content makes allergy control the main concern for B2B buyers. Monel Frames: Key Facts for Importers and Brands For importers and brands, monel metal frames offer a low-cost entry into metal eyewear. However, they also carry a higher risk of nickel allergy complaints. Buyers should understand the key facts before placing an order. Nickel content: Monel contains 63–70% nickel, one of the highest levels in eyewear metals. Allergy risk: Nickel is the most common cause of contact allergy. Monel frames without proper plating can trigger skin reactions. Plating requirement: Monel frames must be plated with layers that block nickel release. Common plating includes copper, nickel, and a final layer of gold, palladium, or chrome. Nickel release standard: The EU REACH regulation limits nickel release to 0.5 µg/cm²/week for items in prolonged skin contact. EN 16128 is the standard test method. Market restrictions: Some markets, especially in Europe, require nickel release testing for metal frames. Monel frames must pass this test to be sold legally. Alternative materials: Stainless steel 316L, titanium, and beta titanium offer lower or zero nickel release. Cost advantage: Monel is cheaper than titanium and stainless steel, making it suitable for value lines. Durability: Monel frames are strong and hold shape well. Durability depends on plating thickness and hinge quality. The question are monel frames hypoallergenic has a clear answer: monel itself is not hypoallergenic because of its high nickel content. However, monel frames can be made suitable for nickel-sensitive wearers if the plating is thick enough and the nickel release passes the required test. This is why buyers must confirm plating specification and test reports. Monel Frames for Wholesale and Custom Programs For wholesale and custom programs, monel frames work best for value and mid-market metal collections. They allow buyers to offer metal frames at a lower price point than titanium or stainless steel. However, buyers should plan for nickel release testing and clear labeling for sensitive-skin customers. Common strategies for monel eyeglass frames in B2B programs include: Value metal lines: Monel frames with standard plating for budget-conscious markets. Nickel-free upgrade: Monel frames with thick nickel-free plating for EU and regulated markets. Mixed collections: Monel for value lines, stainless steel for mid-market, titanium for premium. Kids and teen frames: Monel is less common for kids because of allergy risk; TR90 is a safer choice. Labeling: Clear labeling for nickel content helps retailers guide sensitive-skin customers. Testing: Nickel release testing should be included in the quality control plan. Buyers can also consider nickel-free alternatives such as custom optical frames in stainless steel or titanium, which avoid the allergy issue entirely. Monel Frames: Specifications B2B Buyers Should Confirm Before approving a quotation or sample, confirm these specifications: Material: monel grade (Monel 400 or equivalent). Structure: full rim, semi-rimless, or rimless. Plating: layers, thickness, and final surface finish. Nickel release: test report per EN 16128 or equivalent. Size: lens width, bridge width, temple length, and frame width. Weight: target finished weight per frame. Hinge: standard, spring, barrel, or hidden. Logo: laser engraving, stamping, or metal logo plate. Packaging: standard export packing or custom branded packaging. Labeling: nickel content and allergy warning if required by market. Monel Frames: MOQ, Lead Time, and Pricing MOQ, lead time, and pricing depend on the plating specification, structure, and order model. Stock monel frames have the lowest MOQ and fastest lead time. Custom plating and logo branding increase MOQ. Full OEM development with a new design requires the highest MOQ and longest lead time. Typical lead time for stock monel frames is 7–15 days.

Question 16

TR90 is a lightweight, flexible, impact-resistant thermoplastic polyamide for eyewear. It bends and returns to shape, ideal for sport and kids frames.

Accepted Answer

What is TR90? TR90 is a thermoplastic polyamide material developed by EMS in Switzerland for high-performance eyewear. It is known for being lightweight, flexible, and impact-resistant. TR90 frames can bend under pressure and return to their original shape, which makes them popular for sport, kids, and active lifestyle eyewear. For B2B buyers, TR90 offers a strong balance of durability, comfort, and cost. READSUN Optical produces custom TR90 frames for wholesale and OEM/ODM programs. TR90 Frames Explained for Eyewear Brands and Importers What is TR90 glasses material? In simple terms, TR90 is a memory plastic. It belongs to the thermoplastic polyamide family and is produced through injection molding. The material is heated, injected into a mold, and cooled into the final frame shape. The name TR90 comes from the material's memory effect. When the frame is bent, it returns to its original shape instead of breaking. This is why TR90 frames are often used for children, sport, and outdoor eyewear, where flexibility and impact resistance matter most. Property TR90 Cellulose Acetate Base material Thermoplastic polyamide Plant-based cellulose acetate Production Injection molding Sheet cutting and polishing Weight Very light Medium to heavy Flexibility High; memory shape return Low; rigid but adjustable with heat Impact resistance High Medium Color range Solid colors, matte and gloss finishes Rich layered, transparent, tortoiseshell Repairability Limited; not easily polished or reshaped Good; can be polished and heated Best for Sport, kids, active lifestyle, value lines Fashion, premium, private label This comparison explains the common TR90 vs acetate question. TR90 wins on flexibility, weight, and impact resistance. Acetate wins on color depth, premium feel, and repairability. Many brands carry both materials to cover different market segments.

Question 17

Acetate is sheet-cut plant-based plastic; standard plastic frames are injection-molded. Acetate feels denser, holds richer colors, and can be polished.

Accepted Answer

What is the difference between acetate and plastic frames? All acetate frames are plastic, but not all plastic frames are acetate. Acetate is a plant-based plastic cut from solid sheet, while standard plastic frames are injection-molded from petroleum-based resin. Acetate feels denser, holds richer colors, and can be polished and repaired. Injection plastic is lighter, cheaper, and faster to produce. For B2B buyers, the choice depends on price point, market positioning, and durability target. READSUN Optical produces both acetate and plastic frames for wholesale and OEM/ODM programs. Acetate vs Plastic Frames: Side-by-Side Comparison for B2B Buyers When comparing acetate vs plastic frames, the main differences come down to base material, production method, feel, durability, and cost. The table below gives a quick B2B comparison. Feature Acetate Frames Injection Plastic Frames Base material Cellulose acetate (plant-based) Petroleum-based resin (ABS, PC, nylon, TR90) Production method Sheet cutting, CNC, tumbling, polishing Injection molding into a steel mold Feel and density Dense, solid, premium Lighter, thinner feel Color depth Rich, layered, transparent, tortoiseshell Limited; often painted or sprayed Durability Strong; can be polished and repaired Good; but scratches cannot be polished out Repairability Can be heated and reshaped Cannot be reshaped easily Unit cost Higher Lower MOQ Lower for stock colors; higher for custom colors Higher because a steel mold is required Best for Fashion optical, premium, private label Value lines, kids, sport, promotional frames For B2B buyers, the key point is that acetate vs plastic glasses frames is not just a material comparison. It is also a production and pricing comparison. A factory that produces acetate frames uses different equipment, tooling, and labor than a factory that produces injection plastic frames. Key Differences Between Acetate and Plastic Frames The difference between plastic and acetate frames shows up in several areas that affect the final product and the buyer's margin. Here are the key differences importers and brands should check. Base material: Acetate uses cellulose from cotton linters or wood pulp. Injection plastic uses petroleum-based resin. Production: Acetate is cut from solid sheet. Injection plastic is melted and injected into a steel mold. Weight and feel: Acetate feels denser and more premium. Injection plastic feels lighter and thinner. Color: Acetate holds color through the material. Injection plastic is often painted or sprayed, so color can chip. Repair: Acetate can be polished and heated for adjustment. Injection plastic cannot be repaired the same way. Cost: Acetate has a higher unit cost. Injection plastic is cheaper for high-volume production. Tooling: Acetate uses CNC templates and polishing lines. Injection plastic requires a steel mold, which raises upfront cost but lowers unit cost at high volume. Market position: Acetate suits premium and fashion. Injection plastic suits value, kids, and sport. A common misconception is that acetate is a "different category" from plastic. In fact, acetate is a plastic. The confusion comes from the trade's habit of using "plastic frames" to mean injection-molded frames and "acetate frames" to mean sheet-cut frames. This difference between plastic and acetate frames is the reason the two products are priced and positioned differently. Which Is Better for Your Eyewear Brand: Acetate or Plastic Frames? There is no single answer. It depends on your brand identity, target market, and price point. Acetate frames work best for fashion, premium, and private label collections. Injection plastic frames work best for value lines, kids, sport, and promotional programs. Many successful brands carry both. They use acetate for hero styles and injection plastic for entry-level price points. This gives retailers a wider range without forcing customers into one material. If you are sourcing for the first time, start with a small range of custom optical frames in both materials. Compare weight, color depth, and feel. Then decide which material fits your brand best. Weight, Comfort, and Durability of Acetate and Plastic Frames Injection plastic frames are usually lighter. This can be an advantage for kids, sport, and long-wear comfort. Acetate frames are slightly heavier but feel more solid and premium. For durability, high-quality acetate usually performs better over time because it can be polished and adjusted. Injection plastic frames are strong, but scratches and color chips cannot be repaired. Customization, Colors, and MOQ: Acetate and Plastic Frames Customization options differ by material. Acetate supports rich layered colors, tortoiseshell, transparent, and two-tone effects. Injection plastic supports solid colors and painted finishes. Custom acetate colors usually require higher MOQ because sheet must be ordered. Injection plastic requires a steel mold, which raises upfront cost but lowers unit cost at high volume. For logo and packaging, both materials support laser engraving, silk printing, and metal logo plates.

Question 18

Acetate frames are made from cellulose acetate, a plant-based plastic from cotton linters or wood pulp treated with acetic acid. Sheet-cut and polished, they offer rich colors and premium feel.

Accepted Answer

What are acetate frames made of? Acetate frames are made from cellulose acetate, a plant-based plastic produced by treating cellulose with acetic acid and acetic anhydride. The cellulose usually comes from cotton linters or wood pulp. The result is a strong, glossy, and color-rich material that can be polished, heated, and reshaped. High-quality acetate is often supplied as sheets from Italy or Japan. READSUN Optical produces custom acetate frames for wholesale, private label, and OEM/ODM programs. Acetate Frames: A Plain-English Explanation for B2B Buyers What are acetate frames made of is one of the most common material questions in eyewear sourcing. The answer is cellulose acetate, a natural-origin plastic. Unlike injection-molded plastic, acetate is usually cut from solid sheets, then tumbled, polished, and assembled by hand. This is why acetate frames feel denser and look richer than standard plastic frames. The main raw materials in acetate frame material are: Cellulose: Usually from cotton linters or wood pulp. This is the plant-based base. Acetic acid and acetic anhydride: Used to convert cellulose into cellulose acetate. Plasticizers: Added to improve flexibility and workability. Colorants and pigments: Create solid, transparent, tortoiseshell, and layered colors. Stabilizers: Help the material resist heat, light, and aging. The result is a material that can be transparent, semi-transparent, or opaque. It accepts deep colors, layered patterns, and high-gloss finishes. This is why acetate frames are the standard choice for premium fashion optical frames. Material Main base Production method Typical look and feel Cellulose acetate Cotton linters or wood pulp Sheet cutting, CNC, tumbling, polishing Dense, glossy, premium, rich color depth Injection plastic Petroleum-based resin Injection molding Lighter, matte or painted, lower cost TR90 Thermoplastic polyamide Injection molding Flexible, lightweight, sporty Ultem Polyetherimide Injection molding Thin, heat-resistant, premium slim look Buyers should note that "acetate" and "plastic" are not always the same thing in the eyewear trade. All acetate is a plastic, but not all plastic is acetate. The difference between plastic and acetate frames is mainly the base material, production process, feel, and price level. Acetate Frames: Key Facts B2B Buyers Should Check For importers and brands, what is acetate frame material matters because it affects cost, quality, and market positioning. The table below summarizes the key facts buyers should confirm. Factor What to check Why it matters Sheet origin Italian, Japanese, or domestic sheet Affects color depth, strength, and price Sheet grade Standard, premium, or eco bio-based Affects durability, color stability, and cost Sheet thickness Front and temple thickness Thin sheet may crack; thick sheet adds weight Color type Solid, transparent, tortoiseshell, layered Affects style positioning and market demand Polishing level Rough, fine, mirror polish Affects gloss, scratch resistance, and feel Annealing Tumbling time and stress relief Reduces warping and internal cracks Hinge type Standard, spring, barrel, or hidden Affects durability and repair rate Compliance Nickel release, material safety Required for EU and other regulated markets Another key point is that what is an acetate eyeglass frame is not only about the material. It is also about the production process. Real acetate frames are cut from sheet, not molded. This is why they can be adjusted with heat and polished to remove scratches. Buying Acetate Frames Wholesale: What B2B Importers Should Know When buying acetate frames wholesale, importers should confirm the material source, grade, and production method. These factors explain most of the price difference between suppliers. Two frames can look similar in a photo but perform very differently after six months of wear. Common questions from wholesale buyers include: Which sheet do you use? Italian sheet is often used for premium lines. Domestic sheet is used for value lines. Is the frame cut from sheet or molded? True acetate is cut from sheet. Molded frames are usually injection plastic. How many polishing stages? More stages mean better gloss and scratch resistance. Is annealing included? Annealing reduces warping and internal stress. What colors are available? Solid, transparent, tortoiseshell, layered, and custom colors. What is the MOQ per color? Custom colors usually require higher MOQ than stock colors. Can I mix models in one order? Usually yes, once total quantity meets MOQ. What is the warranty? Confirm coverage for hinge failure, cracking, and color fading. For custom programs, READSUN supports custom optical frames in cellulose acetate with a wide range of sheet options, colors, and finishes. Buyers can also review Manufacturing Excellence for production and quality details. Acetate Frames: Specifications B2B Buyers Should Confirm Before approving a quotation or sample, confirm these specifications: Material: cellulose acetate (sheet-cut, not molded).

Question 20

Spectacle frames are the British and international term for optical or eyeglass frames that hold prescription lenses. They come in full rim, semi-rimless, and rimless styles.

Accepted Answer

What are spectacle frames? Spectacle frames are the frames that hold prescription lenses, and the term is the standard British and international word for optical frames or eyeglass frames. In B2B supply, spectacle frames are usually sold as frames only, without lenses. They can be made from acetate, TR90, Ultem, titanium, stainless steel, and other materials. READSUN Optical manufactures custom spectacle frames for wholesale, private label, and OEM/ODM programs. Spectacle Frames: A Plain-English Explanation for B2B Buyers Spectacle frames and optical frames are the same product. "Spectacle" is the traditional British and international term, while "optical frames" and "eyeglass frames" are more common in the US market. Buyers searching for what are spectacles frames are usually looking for the same product definition. The word "spectacles" refers to the complete eyewear item, while "spectacle frames" refers to the frame itself. In wholesale and OEM supply, the frame is usually supplied without lenses, so the buyer can add prescription lenses later through a lens lab or their own supply chain. Term Common in Meaning Spectacle frames UK, Europe, India, international markets Frames for prescription lenses Optical frames Global B2B and manufacturing Same product; frames for optical use Eyeglass frames US market Same product; frames for eyeglasses Glasses frames Everyday and retail use Same product; informal term For B2B buyers, this matters for search coverage. Buyers in different regions use different terms. A brand selling to the UK, India, or Australia should use "spectacle frames" in product titles and descriptions, while a brand selling to the US should use "eyeglass frames" or "optical frames". Spectacle Frames: Key Facts B2B Buyers Should Check When sourcing spectacle frames, buyers should confirm the same key specifications as any optical frame: material, structure, size, hardware, color, and branding. The table below summarizes the main spectacle frame types and features. Category Common options B2B consideration Frame structure Full rim, semi-rimless, rimless Affects durability, weight, and lens fitting Material Acetate, TR90, Ultem, Optyl, titanium, beta titanium, stainless steel, monel Affects cost, weight, allergy risk, and finish Shape Round, square, rectangle, oval, cat-eye, aviator, browline Affects style positioning and market demand Hinge Standard, spring, barrel, hidden Affects comfort, durability, and repair rate Nose pad Adjustable, fixed, integrated Affects nose fit and comfort across markets Size Lens width, bridge width, temple length Affects fit and regional market preference Buyers should also confirm optical frame parts and hardware details. These include the lens rim, bridge, endpiece, temple, hinge, nose pad, temple tip, and screws. Understanding spectacle frame types and parts helps buyers write accurate specifications for the factory. Buying Spectacle Frames Wholesale: What B2B Importers Should Know Buying spectacle frames wholesale is similar to buying optical frames wholesale. The main difference is the search term, not the product. Importers should confirm the following before placing an order: Supply type: Frames only, or frames with lenses? Material: Acetate, TR90, titanium, stainless steel, or other. Structure: Full rim, semi-rimless, or rimless. Size: Lens width, bridge width, temple length, and frame width. Hinge type: Standard, spring, barrel, or hidden. Spring hinges improve comfort and reduce repair rates. Color and finish: Solid, tortoiseshell, transparent, matte, or electroplated. Logo: Laser engraving, stamping, silk printing, metal logo plate, or temple printing. Packaging: Standard export packing or custom branded packaging. MOQ and lead time: Confirm before sampling. For markets that use the term "spectacle frames", product titles, descriptions, and blog content should use the same wording. This improves search visibility and helps buyers find your products using their own language. Spectacle Frames: Specifications B2B Buyers Should Confirm Before approving a quotation or sample, confirm these specifications: Frame structure: full rim, semi-rimless, or rimless. Material: acetate, TR90, Ultem, Optyl, titanium, beta titanium, stainless steel, or monel. Size: lens width, bridge width, temple length, and frame width. Hinge: standard, spring, barrel, or hidden. Nose pad: adjustable, fixed, or integrated. Color and finish: solid, tortoiseshell, transparent, two-tone, matte, or electroplated. Logo: laser engraving, stamping, silk printing, metal logo plate, or temple printing. Packaging: standard export packing or custom branded packaging. Spectacle Frames: MOQ, Lead Time, and Pricing MOQ, lead time, and pricing depend on the material, structure, and order model. Stock spectacle frames have the lowest MOQ and fastest lead time. ODM modification allows logo, color, and packaging changes with medium MOQ. Full OEM development gives you a unique design and requires higher MOQ. Typical lead time for ODM spectacle frames is 30–45 days after sample approval. Full OEM styles may take 45–75 days. Material also affects cost: acetate, TR90, titanium, and stainless steel have different production processes and price levels. For an accurate quotation, share your target frame style, material, structure, quantity, logo, packaging, and destination market. READSUN will recommend the best production path.

Question 21

Unisex optical frames fit both men and women using neutral shapes and mid-size ranges (50–56 mm lens). One model serves two customer groups, cutting SKU count.

Accepted Answer

What are unisex optical frames? Unisex optical frames are eyeglass frames designed to fit and suit both men and women. They use neutral shapes, balanced proportions, and a mid-size range that works across genders. For B2B buyers, unisex optical frames are a smart way to reduce SKU count while covering two customer groups with one model. READSUN produces custom unisex optical frames for wholesale, private label, and OEM/ODM programs. Unisex Optical Frames: A Plain-English Explanation for B2B Buyers Unisex optical frames are not a separate material or structure. They are a design and sizing approach. A unisex frame avoids very narrow or very wide proportions, and it uses colors and shapes that appeal to a broad audience. Common examples include round metal frames, slim rectangle frames, soft square acetate frames, and minimalist rimless styles. The key idea is range. A unisex frame should fit a wide range of face shapes without looking clearly masculine or feminine. This is why size selection matters as much as shape. Feature Typical unisex range Why it matters Lens width 50–56 mm Covers most adult face widths Bridge width 16–20 mm Fits a broad range of nose shapes Temple length 140–148 mm Comfortable for most adult head sizes Frame shape Round, soft square, rectangle, panto, browline Neutral look that suits both genders Colors Black, tortoiseshell, crystal, grey, navy, gold, silver Broad appeal across markets Materials Acetate, TR90, titanium, stainless steel Different price points and comfort levels These ranges are a guide, not a rule. Buyers should confirm the final size with the factory specification sheet. For markets with smaller or larger average face sizes, unisex frames can be adjusted within a range. Unisex Optical Frames: Key Facts B2B Buyers Should Check For importers and brands, unisex eyeglasses frames offer real commercial value. The main benefit is inventory efficiency. One model can serve two customer groups, which reduces stock risk and improves sell-through. Here are the key facts to check before ordering. Size range: Confirm lens width, bridge width, and temple length cover your market. Shape: Choose neutral shapes that do not lean strongly masculine or feminine. Color: Pick colors with broad appeal. Black, tortoiseshell, crystal, and grey are safe. Bold colors may limit the audience. Material: Acetate and TR90 suit most price points. Titanium and stainless steel work for premium unisex lines. Weight: Lighter frames feel more comfortable for all-day wear and suit both genders. Hardware: Spring hinges and adjustable nose pads improve fit across different face shapes. Branding: Neutral logo placement keeps the frame suitable for both men and women. Packaging: Neutral packaging supports unisex positioning. The commercial logic is simple. A unisex range lets a retailer or brand cover more customers with fewer SKUs. This reduces inventory cost, improves stock turnover, and simplifies buying decisions for the end customer. Buying Unisex Optical Frames Wholesale: What B2B Importers Should Know When buying unisex optical frames wholesale, importers should think about the size curve first. A single unisex model in one size may not fit all customers. A better approach is to offer one or two unisex sizes per model, such as a medium and a medium-large. Common questions from wholesale buyers include: What size range should I order? Start with 52-18-145 and 54-18-145 for adult markets. How many colors per model? Two to four neutral colors usually work best for unisex lines. Which materials sell best? Acetate for fashion, TR90 for active and kids, titanium for premium. Can I mix models in one order? Yes, mixed models are usually allowed once the total quantity meets MOQ. Can I customize logo and packaging? Yes. ODM and OEM programs support logo and packaging customization. For custom programs, READSUN supports custom unisex optical frames with flexible material, color, size, and logo options. Buyers can also review custom optical frames for the full range of frame structures and materials. Unisex Optical Frames: Specifications B2B Buyers Should Confirm Before approving a quotation or sample, confirm these specifications: Size: lens width, bridge width, temple length, and frame width. Shape: round, soft square, rectangle, panto, browline, or rimless. Material: acetate, TR90, Ultem, titanium, beta titanium, or stainless steel. Color and finish: solid, transparent, tortoiseshell, matte, or electroplated. Hardware: hinge type, nose pads, and temple tips. Weight: confirm the finished weight for comfort. Logo: laser engraving, stamping, silk printing, or metal logo plate. Packaging: standard export packing or custom branded packaging. Unisex Optical Frames: MOQ, Lead Time, and Pricing MOQ, lead time, and pricing depend on the material, color count, and customization level. Stock unisex frames have lower MOQ and faster lead time. ODM modification allows logo and color changes with medium MOQ. Full OEM development gives you a unique unisex design and requires higher MOQ. Typical lead time for ODM unisex frames is 30–45 days after sample approval. Full OEM styles may take 45–75 days. For an accurate quotation, share your target size range, material, quantity, color, logo, packaging, and destination market.

Question 22

Full rim frames surround the lens fully and are most durable. Semi-rimless use a top rim and nylon cord. Rimless mount lenses directly.

Accepted Answer

What is the difference between full rim, semi-rimless and rimless frames? Full rim frames surround the entire lens with frame material. Semi-rimless frames hold the lens partly with frame and partly with a nylon cord. Rimless frames mount the lens directly to the bridge and temples without a surrounding rim. Full rim is the most durable and common. Semi-rimless is lighter with a modern look. Rimless is the lightest and most minimal, but also the most fragile. READSUN produces all three frame structures for wholesale and custom programs. Full Rim vs Semi Rimless vs Rimless Frames: Side-by-Side Comparison for B2B Buyers When comparing full rim vs semi rimless vs rimless frames, the main differences come down to appearance, weight, durability, lens fitting, and target market. The table below gives a quick B2B comparison. Feature Full Rim Semi-Rimless Rimless Frame coverage Full rim around the lens Top rim only; bottom held by nylon cord No rim; lens mounted directly Weight Heaviest of the three Medium weight Lightest Durability Highest; lens well protected Good; cord can wear over time Lowest; lens edges exposed Lens security Very secure Secure but depends on cord tension Depends on mounting screws and holes Look Classic, bold, versatile Modern, lighter appearance Minimal, almost invisible Best for Everyday wear, kids, high-prescription lenses Fashion optical, light prescription Premium minimal, low-prescription lenses Repair needs Low; strong structure Medium; cord replacement needed High; screws and lens holes need care For B2B buyers, the choice is not about which is "best". It is about matching the structure to the market, price point, and customer needs. Many brands carry all three structures to cover different segments. Key Differences Between Full Rim and Semi Rimless vs Rimless Frames The frame types full rim, semi-rimless, and rimless each have their own strengths and weaknesses. Here are the key differences importers and brands should check. Full rim frames: The lens is fully surrounded. Strong, safe, and suitable for thick lenses. The most common structure in wholesale. Semi-rimless frames: The top rim holds the lens, and a nylon cord supports the bottom. Lighter look, but the cord must be replaced over time. Rimless frames: The lens is drilled and mounted to the bridge and temples. Very light and minimal, but the lens edge is exposed. Other differences include lens thickness, prescription range, and repair cost. Rimless and semi-rimless frames usually work best with thin lenses. Full rim frames can handle thicker prescriptions and offer better protection. Which Is Better for Your Eyewear Brand: Full Rim or Semi Rimless vs Rimless Frames? There is no single answer. It depends on your brand identity, target customer, and price point. Full rim frames suit family and value collections. Semi-rimless frames work well for fashion and professional markets. Rimless frames are best for premium, minimalist, and lightweight lines. If you are sourcing for the first time, start with a small range of full rim and semi-rimless styles. Add rimless once you understand your customer demand. For buyers who want a flexible frames-only option, custom optical frames cover all three structures. Weight, Comfort, and Durability of Full Rim and Semi Rimless vs Rimless Frames Rimless frames are the lightest and most comfortable for long wear. Semi-rimless frames are slightly heavier but still light. Full rim frames are the heaviest but also the most durable and protective. For durability, full rim wins. For comfort and minimal look, rimless wins. Semi-rimless sits in the middle. Customization, Colors, and MOQ: Full Rim and Semi Rimless vs Rimless Frames Customization options are similar across all three structures. You can customize colors, logo, temple arms, nose pads, and packaging. MOQ depends on the material and customization level. Full rim and semi-rimless frames often have lower MOQ because they use standard tooling. Rimless frames may require extra drilling and mounting steps, which can affect MOQ and lead time. How READSUN Produces Both Full Rim and Semi Rimless vs Rimless Frames at Scale READSUN Optical is a B2B eyeglass frame manufacturer with experience producing all three frame structures. Our factory supports acetate, TR90, titanium, stainless steel, and monel production. We handle sampling, tooling, logo branding, packaging, and quality inspection.

Full Rim vs Semi Rimless vs Rimless Frames FAQ What is the difference between full rim and semi-rimless frames? Full rim frames surround the entire lens with frame material. Semi-rimless frames have a top rim only, with the bottom of the lens held by a nylon cord. Full rim is more durable; semi-rimless is lighter. What is the difference between semi-rimless and rimless frames? Semi-rimless frames still have a top rim, while rimless frames have no rim at all. Rimless lenses are drilled and mounted directly to the bridge and temples. Which is stronger, full rim or rimless frames? Full rim frames are stronger because the lens is fully protected by the frame. Rimless frames are more fragile because the lens edges are exposed and the mounting screws can loosen. Are rimless eyeglass frames good for daily wear? Rimless frames are good for light daily wear, but they need more care. They are best for low-prescription lenses and customers who prefer a minimal look. Can I order semi-rimless eyeglass frames wholesale? Yes.

Accepted Answer

Question 24

Measure eyeglass frame size by checking the temple first, or use a ruler to measure lens width, bridge width, and temple length in millimeters. READSUN helps B2B buyers confirm frame sizes.

Accepted Answer

How do I measure eyeglass frame size? To measure eyeglass frame size, use a ruler or caliper to check three numbers: lens width, bridge width, and temple length in millimeters. Most frames already print these numbers on the inside of the temple. If the numbers are missing, you can measure them yourself in three simple steps. READSUN supplies custom optical frames in all standard sizes and can help confirm specifications before ordering. How to Measure Eyeglass Frames: Step-by-Step Guide Measuring eyeglass frame size is simple if you follow a clear order. You only need a ruler with millimeter markings or a digital caliper. Always measure in millimeters, because frame sizes are not given in inches. Check the temple first. Look inside the temple arm for printed numbers such as 54-18-145. This is the fastest way to find the size. Measure the lens width. Place the ruler across the widest part of one lens rim. Record the number in millimeters. Measure the bridge width. Measure the distance between the two lens rims at the narrowest point of the bridge. Measure the temple length. Measure from the hinge to the end of the temple tip, following the curve. Measure the frame width (optional). Measure the total front width from the outer edge of one endpiece to the other. Measure lens height and ED (optional). Measure the lens rim vertically for B size, and diagonally for ED. Measurement How to measure Typical range Lens width (A) Widest horizontal point of one lens rim 40–62 mm Bridge width (DBL) Narrowest distance between the two lens rims 14–24 mm Temple length Hinge to end of temple tip 120–150 mm Frame width Outer endpiece to outer endpiece 120–150 mm Lens height (B) Vertical height of the lens rim 25–50 mm ED Longest diagonal of the lens shape 45–65 mm What to Prepare Before You Start: How to Measure Eyeglass Frames Before you measure frames for glasses, prepare the right tools and a clean workspace. Accurate measurement depends on steady hands and the correct instrument. Ruler or caliper: Use a ruler with 1 mm markings, or a digital caliper for higher accuracy. Flat surface: Place the frame on a table so it does not move. Good lighting: Bright light helps you read the markings and see the edges clearly. Reference frame: If you are matching a size, keep the original frame nearby. Specification sheet: If you are preparing an OEM order, have your target size template ready. If the numbers are already printed on the temple, use them first. Measuring is only needed when the markings are missing or unclear. For OEM programs, always confirm the size against the factory specification sheet. How to Measure Eyeglass Frames: Common Mistakes to Avoid Small errors in measurement can cause big problems in production. Avoid these common mistakes when you measure frames for glasses. Measuring in inches: Always use millimeters. Frame sizes are standard in mm. Measuring the lens, not the rim: Lens width is the inside rim width, not the lens itself. Straight-lining the temple: Follow the curve of the temple when measuring length. Ignoring the bridge curve: Measure the narrowest point, not the widest. Using a worn ruler: A bent or faded ruler gives wrong numbers. Skipping the second eye: Check both lenses to confirm symmetry. If you are measuring for a new brand, record several samples. This helps you see the natural size range of your target market. How to Measure Eyeglass Frames Documents and Timelines When you prepare an OEM or ODM order, you need more than a single measurement. Prepare these documents before contacting the factory: Size specification sheet: A, B, ED, bridge, temple, and frame width. Reference sample or photo: Helps the factory match shape and proportion. Material and color: Affects tooling and production planning. Logo and packaging: Affects sampling and lead time. Target quantity: Affects MOQ, pricing, and production schedule. Typical timeline for a new size development is 15–30 days for sampling, then 30–45 days for bulk production, depending on material and quantity. Standard sizes ship faster. Cost and Lead-Time Impact on How to Measure Eyeglass Frames Accurate measurement reduces cost and lead time. Wrong measurements cause rework, new tooling, or rejected samples. These problems add cost and delay the launch. Standard size: Lowest cost and fastest lead time. Size adjustment: Moderate cost and lead time. New size development: Highest cost and longest lead time. Share complete measurements with the factory. This avoids back-and-forth emails and keeps the project on schedule.

Question 25

Numbers on eyeglass frames are measurements: lens width, bridge width, and temple length in mm (e.g., 54-18-145). A, B, and ED show lens dimensions. READSUN supplies custom frames in all sizes.

Accepted Answer

What do the numbers on eyeglass frames mean? The numbers on eyeglass frames are eyeglass frame measurements, not prescription values. They usually show lens width, bridge width, and temple length in millimeters, printed as three numbers such as 54-18-145. Some frames also include A, B, and ED dimensions. These markings help B2B buyers confirm fit, size, and specification before ordering. READSUN produces custom optical frames in all standard measurements. Eyeglass Frame Measurements: Definition and Key Features for B2B Buyers Eyeglass frame measurements meaning: the numbers describe the physical size of the frame. They are different from lens prescription values. The most common format is three numbers separated by a square symbol (□) or dashes. Marking Name What it measures Example First number Lens width (A size) Width of one lens at its widest point 54 mm Second number Bridge width (DBL) Distance between the two lenses 18 mm Third number Temple length Length of the temple from hinge to tip 145 mm A size Lens width Horizontal width of the lens rim 54 mm B size Lens height Vertical height of the lens rim 38 mm ED Effective diameter Longest diagonal of the lens shape 60 mm The □ symbol on a frame often separates the lens width and bridge width. For example, “54□18-145” means 54 mm lens, 18 mm bridge, and 145 mm temple. Some frames use a dash instead. The A, B, and ED markings are common in glasses frame measurements for lens cutting and frame fitting. Eyeglass Frame Measurements: Key Facts for Importers and Brands For importers and brands, understanding eyeglass frame measurements is essential for product selection, size range planning, and OEM communication. The table below summarizes the key facts. Lens width (A): affects overall frame width and face fit. Bridge width (DBL): affects nose fit and comfort. Temple length: affects how the frame sits behind the ear. Lens height (B): affects lens coverage and style. Effective diameter (ED): affects lens cutting and thickness. Frame width: total front width, sometimes printed as a separate number. These measurements help buyers avoid size mismatches. They also help factories set tooling and quality checks. When you request a quote, always share the full measurement set, not just one number. Eyeglass Frame Measurements for Wholesale and Custom Programs For wholesale and custom programs, frame measurements drive MOQ, lead time, and pricing. Stock frames come in standard measurements. ODM modification can adjust color, logo, and some dimensions. Full OEM development allows new measurements, but requires tooling and samples.

Question 26

Eyeglass frame sizes use three numbers: lens width, bridge width, and temple length in millimeters (e.g., 54-18-145). Sizes vary by market. READSUN supplies custom frames in all standard sizes.

Accepted Answer

How do eyeglass frame sizes work? Eyeglass frame sizes work with three numbers, usually printed on the temple: lens width, bridge width, and temple length, measured in millimeters. For example, 54-18-145 means a 54 mm lens, an 18 mm bridge, and a 145 mm temple. These numbers help buyers match frames to different face shapes and market preferences. READSUN produces custom optical frames in all standard sizes. Eyeglass Frame Sizes Explained for B2B Buyers Eyeglass frame sizes explained: the three-number system tells you the key measurements of a frame. It is the fastest way to compare frames across models and suppliers. The numbers are always in millimeters. Number Name What it measures Typical range First Lens width Width of one lens at its widest point 40–62 mm Second Bridge width Distance between the two lenses 14–24 mm Third Temple length Length of the temple from hinge to tip 120–150 mm Some frames also print the frame width or lens height. These extra numbers help with fit, but the three main numbers are the standard for optical frame sizes. Buyers should always confirm the size before placing a wholesale or OEM order. Eyeglass Frame Sizes Chart: What Each Number Means Below is a simple eyeglass frame sizes chart to help you read the markings on any frame. 54-18-145: 54 mm lens, 18 mm bridge, 145 mm temple. A common adult size. 50-16-140: 50 mm lens, 16 mm bridge, 140 mm temple. A smaller adult or teen size. 58-20-150: 58 mm lens, 20 mm bridge, 150 mm temple. A larger or wide-fit size. 46-14-135: 46 mm lens, 14 mm bridge, 135 mm temple. A kids or petite size. These are examples. Actual sizes vary by model and material. For eyewear frame sizes, always use the factory specification sheet, not an online guess. Optical Frame Sizes and Market Preferences Different markets prefer different optical frame sizes. Understanding these preferences helps B2B buyers choose the right inventory. North America and Europe: Often prefer medium to large lens widths (52–58 mm) and longer temples (145–150 mm). Asia: Often prefer smaller lens widths (46–52 mm), shorter temples (135–145 mm), and lower bridge fit. Kids and teens: Smaller lens widths (40–48 mm), shorter temples (125–140 mm), and flexible materials. Sport and safety: Wider frames with secure temple grip and larger lens coverage. When you source for multiple markets, a size range is better than a single size. READSUN supports custom optical frames in all standard sizes, plus custom sizing for OEM programs. Eyeglass Frame Sizes: Specifications B2B Buyers Should Confirm Before approving a quotation or sample, confirm these size details: Lens width: width of one lens in mm. Bridge width: distance between lenses in mm. Temple length: hinge to tip in mm. Frame width: total front width in mm. Lens height: vertical lens height in mm.

Question 28

Eyeglass frames are classified by structure, material, and shape. Types include full rim, semi-rimless, rimless, acetate, TR90, titanium, and stainless steel. READSUN supplies wholesale and custom.

Accepted Answer

What are the different types of eyeglass frames? There are three main ways to classify eyeglass frame types: by structure, by material, and by shape. Structure includes full rim, semi-rimless, and rimless. Materials include acetate, TR90, Ultem, titanium, and stainless steel. Shapes include round, square, cat-eye, and aviator. READSUN manufactures all major eyeglass frame types for wholesale and custom programs. Eyeglass Frames: Definition and Key Features for B2B Buyers Eyeglass frames are the front frame and temples that hold prescription lenses. For B2B buyers, the types of eyeglass frames matter because they affect weight, comfort, durability, lens fitting, price, and target market. The three main classification methods are structure, material, and shape. Classification Common types B2B consideration By structure Full rim, semi-rimless, rimless Affects weight, lens security, and repair needs By material Acetate, TR90, Ultem, Optyl, titanium, beta titanium, stainless steel, monel Affects cost, durability, allergy risk, and finish By shape Round, square, rectangle, oval, cat-eye, aviator, browline, geometric Affects style positioning and market demand Eyeglass Frames: Key Facts for Importers and Brands Different eyeglass frame types serve different customer segments. Importers and brands should match the frame type to the market, price point, and brand identity. Below are the key facts for common glasses frame types and spectacle frame types. By structure: full rim, semi-rimless, and rimless Full rim frames: The lens is fully surrounded by the frame. Strong, versatile, and the most common type. Semi-rimless frames: The lens is held partly by the frame and partly by a nylon cord. Lighter look, but requires careful lens fitting. Rimless frames: The lens is mounted directly to the bridge and temples. Minimal look and very light, but more fragile in daily use. By material: eyeglass frame material types Acetate: Plant-based plastic with rich colors and a premium feel. Popular for fashion optical frames. TR90: Lightweight, flexible, and impact-resistant. Good for sport, kids, and active users. Ultem: Heat-resistant, thin, and strong. Used in premium slim frames. Optyl: Thermoset epoxy with a lightweight, skin-friendly feel. Common in European collections. Titanium and beta titanium: Light, strong, and corrosion-resistant. Beta titanium offers more flexibility. Stainless steel and monel: Durable metal options. Stainless steel is better for nickel-sensitive markets. By shape: optical frame types for different markets Shape is one of the fastest ways to build a collection. Common optical frame types include round, square, rectangle, oval, cat-eye, aviator, browline, and geometric. Shape trends change by region and season, so buyers should review local demand before placing bulk orders. Eyeglass Frames for Wholesale and Custom Programs For wholesale and custom programs, the right frame type depends on your target price, MOQ, and customization level. Stock eyeglass frames are fastest to ship. ODM modification allows logo, color, and packaging changes. Full OEM development gives you a unique frame shape, material, and brand identity. READSUN supports custom optical frames across all major frame types. Buyers can choose from acetate, TR90, titanium, stainless steel, and other optical frame materials.
