Custom TR90 Kids Glasses Optical Frame Flexible Spectacle Frames






A flexible TR90 kids optical frame supplied as a frame-only platform for prescription glazing.
Overview
The OTRK509031 is listed as a TR90 thermoplastic optical frame in the Kids Optical Frame range, and it is supplied to optical importers, chain buyers and private-label programmes rather than to single retail customers. Temples are moulded as one piece with the tips, which removes the separate acetate tip that usually works loose first.
TR90 is a thermoplastic polyamide rather than a rigid acetate: bend a temple and it springs back to its original line instead of holding the bend. That memory is what makes the material worth the tooling cost on a frame that will be dropped, sat on and pulled off one-handed. TR90 frames are also noticeably lighter than acetate at the same front size, which matters because weight on a small nose bridge is what turns a pair of glasses into something the wearer wants to take off.
This custom tr90 programme covers tr90 kids glasses and the wider kids glasses optical frame range, giving buyers one optical frame platform for flexible spectacle frames in every colourway we stock. Every order is built against an approved sample, so the colour, the temple length and the lens specification are fixed before production starts rather than negotiated after the first carton is packed.
Minimum order quantity, colour minimums and the certification required for your market are confirmed with the quotation, because they depend on the colour count, the destination and whether the order runs on existing tooling.
Key Features
Material and Frame Build
Front and temples are moulded as a matched pair from the same compound, so the flex in the arm matches the flex in the rim; where the design allows, the tip is formed in one piece with the temple, removing the joint that usually splits first. Surfaces are tumbled and then hand-buffed so the mould parting line disappears around the brow, and the colour is pigmented through the material rather than painted on, so a scratch does not show a white line.
Fit for Children
Temple length is shortened and the bridge is raised so the front sits on a nose that is still growing, and the tips are rounded to clear the area behind the ear that a child presses hardest. Hinges are chosen for flex rather than for a tight fold, because the frame is usually taken off with one hand.
Lens and Optical Performance
The frame ships frame-only with demo lenses fitted, ready for the optical lab to glaze. Demo lenses protect the rim during transit and are removed before prescription lenses are cut and mounted. Frames are checked on a lens-meter after mounting, and any pair that sits outside the agreed tolerance is re-edged rather than shipped.
Colour, Logo and Tooling
Colour is quoted against a Pantone reference and matched on a master sample before the run. Logo placement is confirmed at quotation stage. Existing tooling keeps a repeat order identical to the first shipment without a new mould charge, and artwork is proofed on the temple surface before the run.

OEM & ODM Customization
Custom work on this model is handled in two ways. OEM orders keep the existing front and change what sits on it: colour, logo, lens treatment and packaging. ODM orders start from the same platform but allow a new front shape, a different temple profile or a size run built around a specific market, which needs a new mould and a longer development window.
Both routes begin with a technical brief rather than a picture. We ask for the target market, the lens specification, the size range, the branding position and the packaging format, because those five answers decide which parts of the frame can stay standard and which have to be re-cut.
- Colour matching to a Pantone reference, with a sprayed or moulded master sample approved before production.
- Logo application by hot stamp, temperature transfer, laser or metal plate, chosen to suit the surface and the expected wear.
- Lens options including clear, tinted, UV400 and blue-light filtering, with the base curve matched to the front.
- Packaging from a plain poly bag to a printed case, a card-backed blister or a counter display box.
- Size grading within one tooling family, so a range can cover more than one fit without a second mould.
- Artwork files, colour proofs and a pre-production sample supplied for buyer sign-off before the line runs.
If you already have a specification sheet, send it with the enquiry and we will mark which items are standard, which are a tooling change and which fall outside the platform. That answer is more useful than a price list, because it tells you where the real cost sits. For buyers who want the wider programme, the OEM and ODM frame service page sets out the full development sequence.
Manufacturing & Quality Control
Quality is handled at four fixed points rather than at the end of the line, so a fault is caught while it is still cheap to correct.
1. Incoming Material Inspection
Acetate sheet, moulding compound, metal components and lenses are checked on arrival against the approved reference: colour, thickness, hinge type and lens base curve. A batch that does not match is held before it reaches the assembly bench.
2. Moulding and Frame Assembly
Fronts and temples are produced to the drawing, then joined with the specified hinge. Each assembly is checked for symmetry, temple angle and hinge tension, because a frame that is out of line cannot be corrected by adjusting the lens later.
3. Surface Finishing and Optical Check
Tumbling, polishing and any coating are inspected under a light box for scratches, sink marks and colour drift between front and temples. Glazed orders are read on a lens-meter, and the optical centre is verified against the ordered specification.
4. Packing and Final Inspection
Finished pairs are cleaned, bagged and packed to the agreed carton configuration, then sampled to an AQL plan before the carton is sealed. Carton marks, barcodes and assortment ratios are checked against the order sheet a second time at dispatch.
The full sequence, including the inspection records kept for each lot, is described on the quality control page.
Applications
This model is bought by trade customers who need a repeatable optical frame rather than a single pair, and it fits the following programmes.
- Retail channels including optical chains and independent opticians, buying groups, online prescription retailers, and distributors serving school-age screening programmes; here the specification has to stay identical across repeat orders.
- Private-label collections where the buyer supplies a logo and a colour reference but not a drawing.
- Promotional and seasonal programmes that need a low unit cost with certification already in place.
- Distributors building a size or colour run from one tooling family instead of several suppliers.
- Online sellers who need consistent product photography and a specification they can publish.
- Trial orders before a full season commitment, using the sample process to validate the fit.
The rest of the range sits under Kids Optical Frame, and if you are comparing shapes or materials before choosing, the custom optical frame overview is the quickest place to start.
FAQ
What is the minimum order quantity?
The minimum order quantity is confirmed at quotation stage because it depends on the colour count and on whether the order runs on existing tooling. Sample pairs can be supplied for approval first. The certification position is confirmed with the quotation.
How long does a sample take?
Stock colours can usually be sampled from existing frames, while a custom colour or a logo change needs a new sample to be built. The exact lead time depends on the material and on whether a mould change is involved, so it is confirmed at quotation stage rather than promised here. Courier time is additional and depends on the destination.
Can I add my logo and my own packaging?
Yes. Logo can be placed on the temple or the lens corner, and packaging can be a printed case, a card-backed blister or a counter box. Send the artwork in a vector format with the Pantone references, and a proof is issued before the sample is made, because a logo that is approved on screen can still fail on a curved temple.
Start Your Custom Order
Send the model number, the colour reference, the lens specification and the quantity you have in mind, and you will get a quotation with the tooling position marked clearly. If the brief is still open, say so: we can quote two or three configurations against the same front so the cost difference is visible before you commit.
