Problems solved by technology

[0002] At present, most of the lenses sold in the market are resin lenses, which are easy to grind, and generally require coating to increase the wear resistance of the lens. The superhard waterproof coating material technology currently used is monopolized by foreign countries, and the cost is high. Luminosity still needs to be further improved

Abstract

The invention discloses superhard waterproof plated film lenses of spectacles. Each lens sequentially comprises, from top to bottom, an optical resin lens, an anti-reflection film layer, a combination film layer and a superhard water-proof film layer. The superhard water-proof film layer is prepared in a way that N-perfluoro-1-octanesulfonyl fluoride aminopropyltriethoxysilane is adopted to serve as a main raw material; 130-220ml isopropanol and 15-20g water are added to every 100 grams of N-perfluoro-1-octanesulfonyl fluoride aminopropyltriethoxysilane, and then uniform stirring is performed; 7-10g acid solutions are added to the above solution in a stirring state, and sealing reaction is conducted for 5-8 hours at the temperature of 50-65 DEG C; the filtered solution is filtered and dried, and then amorphous crystals are formed; the crystals are crushed to be 10-18 in mesh, and perfluoro octyl group quaternary amines iodide is added to the crushed crystals. Through the design of combination of multiple film layers, the superhard waterproof plated film lenses of spectacles exhibit excellent wear resistance and low reflectivity.

Description

technical field [0001] The invention relates to the technical field of spectacle lens production, in particular to a superhard waterproof coated spectacle lens. Background technique [0002] At present, most of the lenses sold in the market are resin lenses, which are easy to grind, and generally require coating to increase the wear resistance of the lens. The superhard waterproof coating material technology currently used is monopolized by foreign countries, and the cost is high. The light rate still needs to be further improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a superhard waterproof coated spectacle lens with low cost and high light transmittance. [0004] In order to solve the problems of the technologies described above, the technical solution of the present invention is: [0005] A superhard waterproof coated spectacle lens, which sequentially includes an optical resin lens, an antireflecti...
