[Product Information]

Featured tan lenses tints block almost 100 percent of harmful UV light， strengthen contrast and visual performance， and alleviate eye fatigue by filtering specific short-wavelength blue lights i.e. high-energy visible (HEV) lights， emitted from artificial light sources such as computers， tablets， smart phones， LED lights， TV， and other electronic devices. Exposure of HEV increases the risk of macular degeneration due to the damage to the light-sensitive cells.
Lenses anti-reflective (AR) coating helps virtually eliminate glare and halos and allow for more available light passing through， reducing eye strain and optimizing visual acuity (sharper vision) with fewer distractions. Functional coating layers offer fog， oils or stain-repellent and easy-to-clean features， and abrasion and scratch-resistant benefits.
Ultra-high elastic tan nylon lenses infused with ultra-anti-UV transparent crystal material would not cause scattering of visible lights. Excellent resistance to stress， cracking and chemical makes it the first choice of material for high-end lenses， doubling the cost of ordinary lenses. Lenses have passed FDA Drop Ball Test to ensure impact resistance and safety. FDA registered manufacturer and distributor guarantee your satisfaction on the product quality.
