New Multi-Function Round Shape Metal Magnetic Clip-On Optical Frame





A dual-purpose frame where the clip is an engineered part of the front, not an accessory.
Overview
The frame is a two-part system: an optical front that takes prescription lenses, and a sun clip that locates on the brow by magnet rather than by a hook over the lens. Because the clip seats on inserts moulded into the front, the two parts align on the same optical centre every time it is fitted, and the wearer can drop the clip into a case without touching the lenses. The front is made in metal, the clip is fitted with a 0.74 mm polarized clip lens as recorded in the product file, and the assembly is aimed at optical chains, travel-retail buyers and distributors who want one SKU to answer both indoor and outdoor demand.
What a buyer receives is a frame that has been specified rather than assembled from stock parts: material, temple hardware and colour are fixed at sampling, and the production run repeats that specification. The round metal front takes a magnetic clip on the brow, so the same frame serves as an optical pair and as a sun pair. The catalogue lists this model under five search terms: optical frame, magnetic clip-on, round shape metal, metal magnetic clip-on and multi-function round shape. They cover platform, fit and frame family, and all five resolve to model 18C091M, so a request placed under any of them reaches the same tooling and the same specification sheet.
Key Features
The four points below are the ones buyers usually test on a sample: material behaviour, fit geometry, optical performance and the customisation boundary.
Frame Material and Weight
The metal front is drawn thin and then polished, so the rim reads light while still holding a lens under tension. Temple length is set by the tooling, which keeps the fold angle consistent from pair to pair, and the surface is plated before assembly so colour does not shift at the solder points.
Fit, Magnet and Clip Seat
The front and clip are a matched pair: geometry, magnet height and lens decentration are fixed together, so a replacement clip from the same tooling fits without adjustment. That matters for after-sales, where a lost clip should not mean a lost frame.
Optical and Sun Performance
Two lens layers, two jobs: the optical lens corrects, the clip cuts glare. The clip lens is held flat against the front rather than tilted, so there is no prism effect at the edge of the field when the wearer looks sideways.
Colour and Logo Customisation
Colour, logo and packing are fixed at sampling, which means the reorder repeats the approved version instead of re-interpreting it. Minimum order quantity and price breaks are confirmed at quotation stage, because they move with colour count and packing format.
Product Showcase
Photographs below are the approved sample set for model 18C091M: front, angle, temple detail and colour reference. They are the images used for buyer approval, so a reorder is matched against the same reference.

OEM & ODM Customization
Customisation is handled at the tooling and sampling stage rather than at packing, because colour and geometry decisions made late are the ones that create a mismatch between the approved sample and the bulk. The list below is the working boundary for this model: anything inside it is quoted as a variant, anything outside it is quoted as a new development.
- Front colour matched to a Pantone or physical swatch before moulding, with a colour chip retained for the reorder.
- Logo applied by moulding, pad printing or laser marking, depending on where the mark sits and how the material takes ink.
- Clip lens tint and magnet pull specified as part of the same order, so the front and the sun layer stay a matched pair.
- Lens specified at order: tint, coating and, where the brief calls for it, blue-light filtering.
- Temple length and tip curvature adjusted at sampling so the frame fits the target market rather than the sample head.
- Packing configured to the buyer brief: polybag, pouch, case, carton count and barcode label.
Manufacturing & Quality Control
Production runs through four checkpoints, and each one can stop a batch. The sequence is the same for a trial order and for a repeat run, so a buyer who approves a sample knows which checks the bulk will pass through.
1. Incoming Material Inspection
Every incoming lot is checked for colour, hardness and dimensional consistency against the approved sample. Metal parts are checked for plating thickness at the wear points, and any magnetic components are pull-tested before the batch moves to assembly.
2. Moulding and Frame Assembly
Front and temple come off the tool, are trimmed, then matched as a pair. Hinge screws are set to a fixed torque and thread-locked, so the fold tension is the same on the first frame and the last.
3. Surface Finishing and Optical Check
Polishing is followed by a coating stage where the order calls for it. Inspectors check for flow lines, colour drift between front and temple, and any gap at the lens seat before the frame moves to packing.
4. Packing and Pre-Shipment Sampling
Frames are packed to the agreed carton count with a colour and model label on each polybag. A pre-shipment sample is drawn from the finished cartons and checked against the approved sample before the carton is sealed.
The full inspection standard is described on the quality control page, and prototype lead times are set out under rapid prototyping.
Applications
Model 18C091M is ordered by buyers in the following channels. The list is not exclusive, but it describes where the shape, price point and packing have already been placed.
- Optical chains adding a dual-purpose line to a prescription wall
- Travel-retail and airport buyers who need one SKU for indoor and outdoor use
- Distributors supplying drivers, teachers and outdoor workers
- Private-label brands building a clip-on story across several fronts
- Corporate and safety programmes where a single pair covers site and office
- Online sellers who want a product that explains itself in one photograph

FAQ
What is the minimum order quantity for this model?
The product file does not fix an MOQ for this model, so the quantity is confirmed at quotation stage against the chosen colour count and packing. Colour and logo customisation is quoted against the same quantity, so a trial order and a repeat order use one price ladder.
How long does sampling take, and what is needed to start?
Sampling starts once the target colour, logo position and lens specification are confirmed. A stock front can usually be shown from existing samples, while a new colour or a new logo needs a made-up sample. The exact sampling window is confirmed at quotation stage, together with the courier cost and the sample charge, which is credited against the bulk order.
Can the logo and packing be customised?
Logo and packing customisation are available; the exact method depends on the surface the mark sits on and is confirmed at quotation stage. Packing follows the approved carton configuration, and a buyer can specify polybag, pouch or case before the run is released. Artwork is checked on a proof before production, so a spelling or position error is caught before the tooling is touched.
