Embodiment 1
[0035] The optical material of the present invention and the preparation method of lens are as follows: trimethylolpropane tris (mercapto propionate) 536g, mix isophorone diisocyanate (IPDI) 358g, 4,4'-methylene bis (cyclohexyl) Diisocyanate) 106g After preparing the monomer composition, 2-(2'-hydroxy-5'-tert-octylphenyl)-2H-benzotriazole (2-(2'-hydroxy- 5′-t-octylphenyl)-2H-benzotriazole) 18g, 0.9g of dibutyl phthalate as a release agent, 1-hydroxyl-4-(p-methylaniline) anthraquinone (1- Hydroxy-4-(p-toluidine)anthraquinone) (blue) 20ppm, alizarone dyes (red) 10ppm, and dibutyltin dilaurate as a polymerization initiator 1.8g were put into a mixing tank equipped with a stirrer, After replacing with nitrogen and removing the air in the mixing barrel, stir under reduced pressure for 2 hours, stop stirring, degas under reduced pressure, and pour into a glass mold fixed with polyester tape (diopter -5.00).
[0036](2) Put the glass mold injected with the mixture into a steel circu...
