Clip on optical frames

When evaluating Clip On Optical Frames, prioritize frame materials such as Ultem (PEI) or TR90 for their lightweight, flexible, and heat-resistant properties. Ensure the magnetic attachment system uses high-quality Neodymium magnets to prevent the clip-on from detaching during movement. For the lenses, verify that the clip-on components are TAC polarized with 100% UV400 protection to ensure functional value for the end-user.

Optical frames are classified as medical devices in many regions. You must ensure suppliers provide CE Marking for the European market and FDA Registration for the U.S. market. Additionally, products should comply with ISO 12870 (Ophthalmic optics - Spectacle frames) which covers requirements for nickel release, biocompatibility, and bridge distortion resistance.

Request the supplier to perform a bridge deformation test and a magnetic force stability test. The clip-on should remain securely attached even when the frame is subjected to moderate vibration. Check for seamless integration where the clip-on matches the base frame's curvature perfectly to avoid light leakage or lens scratching.

Look for suppliers on Made-in-China.com that offer private labeling (laser logo printing) on the temples and custom packaging sets (e.g., 3-in-1 or 5-in-1 sets with a dedicated pouch). Advanced suppliers should provide CAD design services to create unique frame shapes that align with current fashion trends while maintaining ergonomic nose pad designs for comfort.

The primary risk is quality inconsistency between samples and bulk production, particularly regarding magnet strength. Mitigate this by using Trade Assurance services and hiring third-party inspection agencies (like SGS or Intertek) to conduct a Pre-Shipment Inspection (PSI). Ensure the inspection includes a drop test and a hinge cycle test (minimum 20,000 openings).

Eyewear pricing is highly sensitive to order volume and material choice. For TR90 frames, aim for a target price reduction of 10-15% when ordering over 1,000 units. If you are a startup, negotiate a mixed-color MOQ (e.g., 300 units total but 50 units per color) to test market response without overstocking.

Optical frames are lightweight but high-volume. Use double-walled corrugated cartons with internal bubble wrap protection to prevent frame warping during transit. For shipping to the U.S. or Europe, ensure the Drop Ball Test report is included in the shipping documents to clear customs smoothly, as this is a standard safety requirement for impact resistance.

Always verify the supplier's Business License and Export License on Made-in-China.com. Prioritize Audited Suppliers who have undergone on-site verification. Use secure payment methods such as Letters of Credit (L/C) for large orders or Escrow-based payments to ensure funds are only released upon confirmed receipt of goods meeting your specifications.
