731 Sunglasses with Polarization Barrier and UV Protection for Outdoor Use

Features Tri color light perception : using non representational spectral layering technology (blue/green/red lenses), blocking rate ≥ 99% (compliant with ISO 12312-1 standard), dynamic polarization coating achieves glare suppression in driving scenes (angle deviation ≤ 2 °). Retro mechanics architecture: Black acetate fiber frame (weight ≤ 28g), leg thickness ≤ 3mm, and a matte matte texture on the . engraved anti slip patterns on the mirror legs (concave convex depth of 0.2mm, friction coefficient ≥ 0.65). Full scene adaptation system: Elastic hinge opening and closing life ≥ 50000 times Anti slip silicone nose pad ( pressure ≤ 0.15kg/cm ²) Specifications Category parameter details Material composition: Acetate fiber frame (temperature resistance -20 ℃~80 ℃)+CR39 resin substrate (thickness 1.3mm, Abbe number ≥ 58) Optical performance: Polarization barrier rate ≥ 99.2%+anti blue light coating (barrier rate ≥ 90%) Adaptation range: Adjust the length of the mirror legs to 135-145mm (with an error of ± 0.3mm), and the curvature of the mirror frame is R =8.5mm (fitting the curvature of the human face) Details treatment: hydrophobic coating on the edge of the mirror frame ( angle ≥ 110 °, IPX4 protection level) Gradient enamel decorative strip at the end of the mirror legs (wear resistance coefficient ≥ 4H)

for Structural innovation: Asymmetric curved lens cutting (color difference Δ E ≤ 1.5, 19-4052 blue/16-1539 red/14-0341 green) shock absorption structure in temporal area (absorption rate ≥ 80%) Environmental certification: Certified (no azo dye precipitation) The proportion of recycled materials is ≥ 30% Package Content 1 x European replica polarized sunglasses (including lenses/frames/nose pads)

Note Applicable scenarios: road cycling/self driving travel/outdoor exploration Caution: Avoid between the lens and organic (resistance of the coating is limited to the testing range) Design concept: Through spectral layering technology and retro curved cutting, replicate classic driving aesthetics
