▎ 摘　　要

NOVELTY - Lens comprise base layer, antireflection film layer arranged on outer side of base layer, nano-protective film layer arranged on outer side of antireflection film layer, high-efficiency wear-resistant film layer comprising 1-8 pts. wt. graphene, 12-35 pts. wt. nano-carbon, 10-18 pts. wt. copper oxide, 4-9 pts. wt. glycerol alcohol, 1-8 pts. wt. plant extract and 1-3 pts. wt. aluminum oxide nanoparticles, and waterproof anti-fog film layer arranged on outer side of high-efficiency wear-resistant film layer. USE - As lens. ADVANTAGE - The lens have excellent long-acting, wear-resistance and anti-fog properties, are more clear, prolong the service life of lens, and ensure high-efficiency and improved hardness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the lens, involving (a) placing base layer in cleaning tank, cleaning with ultrasonic waves, and drying after cleaning, (b) passing dried base layer to vacuum chamber for vacuum pumping, (c) sequentially plating outer surface of base layer to antireflection film layer and nano-layer from inside to outside.
