Custom Round Shape Plastic Spring Hinge Reading Glasses in Fluorescent Color



A ready-to-wear reader for shelf and pharmacy display, built to be reordered rather than replaced.
Overview
This reading frame is positioned for volume retail, where the shape has to appeal across ages and the pack has to survive distribution. The front is made in polycarbonate, the lens specification is a reading lens whose power range is confirmed at quotation stage. It is offered to importers, chain buyers and promotional distributors, with colour and logo customisation handled at the tooling stage so the production run stays consistent.
For a buyer, the useful part is the repeatability. Colour is matched against an approved swatch before the run starts, the hinge is tested at the assembly stage rather than at packing, and the front geometry is checked against the sample so a reorder does not arrive with a shape that has drifted. The round front is moulded in a fluorescent colourway, and the spring hinge is plastic rather than metal to keep the frame light. The catalogue lists this model under five search terms: custom round shape, round shape plastic, plastic spring hinge, spring hinge reading glasses and reading glasses. They cover platform, fit and frame family, and all five resolve to model rp394002, 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.
Front Material and Finish
Polycarbonate gives this frame its impact behaviour: the front and temple resist cracking when knocked, which is why the same resin is used for safety and sports eyewear. It also moulds thin, so a deep eye-wire profile can be produced without the weight penalty that acetate would add at the same thickness.
Hinge, Temple and Pocket Fit
Temple length is set for a reader's shorter wearing distance, so the frame sits slightly closer than an optical pair would. That keeps the reading zone centred over the page instead of forcing the wearer to tilt the head.
Lens and Reading Comfort
Power options are confirmed at quotation stage, because a reader is ordered by power mix rather than by a single number. The lens is fitted to the front geometry so the optical centre lands where the wearer actually looks.
Colour, Logo and Packing
Logo position is agreed on the sample, so the mark sits on a flat face rather than over a curve. The minimum order quantity is 1200 pcs, which is the point at which a colour run becomes practical.
Product Showcase
Photographs below are the approved sample set for model rp394002: 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.
- 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
Resin, sheet and temple wire arrive with a batch record. Colour is checked against the approved swatch under daylight, and magnetic inserts, where the model uses them, are tested for pull before the batch is released to moulding.
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.

FAQ
What is the minimum order quantity for this model?
The product file records an MOQ of 1200 pcs for this model, and that is the quantity a colour run is quoted against. 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.
