Core Functions:
1. Dual – material Composite Structure: The TR90 plastic – steel frame is paired with 316L stainless – steel temples, ensuring no deformation at 52°C and achieving an ultra – light wearing experience of 21g (35% lighter than traditional metal frames).
2. Modular Design: The temple and the frame adopt a patented quick – release structure (Patent Number ZL2022XXXXXXX), allowing the lens to be replaced within 5 minutes.
3. Ergonomic Nose Pads: The 3D curved nose pads are designed based on the Asian face shape database, increasing the contact area with the bridge of the nose by 40% and distributing pressure more evenly.
4. UV Protection System: The special sweat – guiding grooves on the inside of the frame, combined with the lenses, achieve 360 – degree ultraviolet ray blocking, with the measured UVA/UVB blocking rate ≥99.7%.

Industry – specific Adaptation Solutions:
– Tourist Attractions: There is a 0.8mm engraving area at the end of the temple, supporting the carving of the attraction LOGO + QR code.
– Corporate Gifts: Pantone color card matching service is provided, supporting the accurate reproduction of corporate VI colors.
– Sports Brands: The hinge structure can be strengthened to pass the 10,000 – time opening and closing test standard.
