Abstract

This invention relates to resin glasses, which comprise: diethylene glycol propenyl dicarbonate (Brite-55) 50-95 wt.%, diethylene glycol propenyl carbonate (RAV 7AT) 0-48 wt.%, 2-(2'-hydroxyl-5-tert-octyl)-benzotriazol (UV-5411) 0.1-0.2 wt.%, inorganic paint B 0.3-0.4 wt.%, inorganic paint A 0.1-0.2 wt.%, diisopropyl peroxydicarbonate (IPP) 1-3.5 wt.%, distyryl dibenzotriazol (UV-0) 0.01-0.5 wt.%. The resin glasses are produced by: preparing the raw materials, filling, curing, treating the substrate glass, returning to the furnace, and treating the glasses. The obtained resin glasses can block total UV (below 400 nm) and blue-violet light (between 400-420 nm), thus can protect eyes from UV and blue-violet damage, and can satisfy the requirements of people in welding locus, banks, UV sterilization rooms, highland, torrid zones, and subtorrid zones.

Description

technical field [0001] The invention relates to an optical material, specifically a spectacle lens and its manufacturing process, especially a resin spectacle lens and its manufacturing process. technical background [0002] At present, resin eyeglass lenses are in a priority position in the eyeglass market competition due to their light weight, high transparency, impact resistance, easy molding, dyeability, and UV protection. Due to the increase in the number of people suffering from cataracts in recent years, more and more attention has been paid to the anti-ultraviolet function and effect of lenses. The most domestic production and sales of resin spectacle lenses, the main ingredients of the formula include: CW-55 (diethylene glycol propylene dicarbonate), CR-39 (diethylene glycol propylene carbonate), UV-5411 [2-(2 '-Hydroxy-5-tert-octylphenyl) benzotriazole], inorganic pigments and IPP (diisopropyl peroxycarbonate), its anti-ultraviolet performance index value is UV360...
