Abstract

The invention relates to an anti-fatigue anti-myopic lens and a production method, belonging to a lens and the production method thereof. The lens is made of the following raw materials based on weight percentage: 72-78% of diallyl terephthalate, 18-24% of diallyl 2,2'-oxydiethyl dicarbonate, 0.08-0.12% of 2-(2-hydroxy-5-tert-octyl phenyl) benzotriazole, 0.18-0.22% of UV absorber 2-(2- hydroxy-3-tert-butyl-5-methyl-phenyl)-5- chloride benzotriazole, 0.2-0.4% of red inorganic pigments, 0.3-0.5% of blue inorganic pigments, 2.3-2.5% of peroxide peroxydicarbonate, and 0.5-0.7% of dibenzoxazole diphenylethylene. The lens has the advantages that as the formula adopts anti-UV raw materials, the lens can effectively reduce eye fatigue, prevent the occurrence and development of myopia, and filter harmful light, such as ultraviolet rays and radiation waves causing eye injury, so that the light becomes soft and comfortable to actually achieve eye protection effect.

Description

technical field [0001] The invention belongs to a spectacle lens and a production process thereof. Background technique [0002] Lenses in the domestic market have single functions, which can easily cause visual fatigue and fail to protect the eyes. The harmful light entering the eyes cannot be filtered out, the light cannot be softened and comfortable, and the eyes of young people are damaged. Contents of the invention [0003] The invention provides a four-proof lens to solve the problem that the lens has a single function, easily causes visual fatigue, and cannot protect the eyes. The technical scheme that the present invention takes is: it is made by the raw material of following weight percent and method: [0004] Diallyl terephthalate: 72% to 78%, diallyl diglycol dicarbonate: 18% to 24%, 2-(2-hydroxy-5-tert-octylphenyl)benzotri Azole 0.08%~0.12%, UV absorber 2-(2-hydroxy-3-tert-butyl-5-methylphenyl)-5-chlorinated benzotriazole: 0.18%~0.22%, red inorganic pigment ...
