Abstract

The invention relates to an anti-blue ray lens, a production method thereof, and glasses including the anti-blue ray lens. The anti-blue ray lens is produced through mixing and cure-molding the following raw materials, by weight, 90-95 parts of polymer resin, 0.2-0.5 part of nano-metal oxide, 0.05-2 parts of an ultraviolet ray absorber, 0.5-2 parts of a blue ray absorber, 0.05-1 part of graphene oxide and 0.01-0.03 part of a toner. All above raw materials are melted and mixed at a high temperature, and then are cure-molded to produce the anti-blue ray lens. The anti-blue ray lens has the characteristics of harmful blue ray reflection, and improvement of the transmittance of beneficial blue rays.

Description

technical field [0001] The invention relates to the field of optical lenses, in particular to an anti-blue light lens, a preparation method and glasses comprising the anti-blue light lens. Background technique [0002] Among visible light, blue light has a short wavelength and high energy, and can directly penetrate the lens to reach the macular area of ​​the eye. A large amount of short-wave blue light with irregular frequency is retained in artificial light sources such as LEDs, computers, and TV screens. Long-term blue light exposure to the retina will generate free radicals, which will easily lead to the decline of retinal pigment epithelial cells and cause eye diseases. [0003] In order to reduce the damage of blue light to the retina, the lens usually needs to be treated. A Chinese patent with an application date of December 15, 2015 and an application number of 201510932531.9 discloses an anti-blue light optical lens, which is composed of multiple film layers sequen...
