Compared with the prior art, the invention has the beneficial effects that:

1. in the invention, UV permeates the inner layer of the lens, surface coating technology is not adopted, so that the ultraviolet resistance effect of the lens is more stable and more durable, a fluorescent whitening agent is added for solving the problem of yellowing of the surface, the problem that the UV permeates the inner layer of the lens to cause yellowing of the bottom color of the lens is counteracted through the whitening effect of the fluorescent whitening agent, and the yellow index is reduced;

2. in the invention, 2.5-bis (5-tert-butyl-2-benzoxazolyl) thiophene or 2.2 '- (4.4' -distyryl) dibenzoxazole and HS-16# powder are adopted, and the HS-16# powder enables a fluorescent whitening agent to detoxify and can absorb a large amount of ultraviolet rays while whitening the 2.5-bis (5-tert-butyl-2-benzoxazolyl) thiophene or 2.2 '- (4.4' -distyryl) dibenzoxazole

3. The application of the green colorant, the blue colorant and the red colorant in corresponding proportion can enhance the light transmission effect of the optical lens, so that the ground color of the optical lens is purer and more transparent, the appearance is better, and the ultraviolet-proof effect of UV powder, the yellow removal effect of fluorescent whitening agent and the detoxification effect of HS-16# powder are supplemented, so that the optical lens is better in all aspects.
