Anti-blue light film for lens

Abstract

The invention relates to the technical field of blue light prevention, and specifically discloses an eyeglass blue light prevention film. The eyeglass blue light prevention film comprises two layers of transparent substrates and a blue light prevention glue layer arranged between the two layers of transparent substrates. The materials of the blue light prevention glue layer comprises, by weight, 100 parts of an adhesive, 0.50-2.15 parts of a blue light absorbent and 10-20 parts of a solvent. The blue light absorbent is a mixer of a compound A and a compound B. The chemical structural formula of the compound A is shown as a formula (I), the chemical structural formula of the compound B is shown as a formula (II), and the mol ratio of the compound A to the compound B is 1-3:2. According to the invention, the compounds A and B are selected as the composite blue light absorbent, both the compound A and the compound B comprise large [pi] bonds, the two compounds have a synergistic effect after being mixed, and the blue light absorption performance is better.

Description

technical field [0001] The invention belongs to the technical field of anti-blue light, and in particular relates to an anti-blue light film for lenses. Background technique [0002] We all know that ultraviolet rays can damage people's glasses, but many people don't know that blue light in visible light can also damage glasses. Blue light is the wavelength of visible light closest to ultraviolet light, its wavelength range is between 400-500nm, and it appears blue in the sense of human eyes. With the rapid development of society, people's lives are filled with various electronic products such as computers, mobile phones, and TVs. People are also increasingly dependent on electronic products, and the screens of electronic products emit a large amount of irregular short-wave blue light. It will directly penetrate the cornea and reach the retina, causing the retina to produce free radicals, which lead to the decline of retinal pigment epithelial cells, and then make the photo...
