Abstract

The invention provides blue-light-resistant resin. The blue-light-resistant resin comprises the following raw materials: mixed resin, an organic solvent, a light stabilizer and a blue light absorber, wherein the mass ratio of the organic solvent to the mixed resin is 1 to (4-5); the mass of the light stabilizer is 1000-5000ppm of that of the mixed resin; the mass of the blue light absorber is 3000-5000ppm or 15000-20000ppm of that of the mixed resin. Through the blue-light-resistant resin, the distribution of the blue light absorber is more uniform; the refractive index is adjusted by adjusting the mass ratio of the mixed resin and the organic solvent; the resin prepared by adding the light stabilizer is capable of shielding or absorbing energy of ultraviolet light; the resin also has the functions of quenching singlet oxygen and decomposing hydroperoxide into inactive substances and is also capable of eliminating or delaying possibility of photochemical reaction and preventing or delaying light aging process; the service life of the blue-light-resistant resin is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of resin lens production, and in particular relates to an anti-blue light resin and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards and the continuous advancement of mobile Internet technology, mobile phone screens, tablet computer screens and notebook screens have penetrated into our daily lives. A large amount of high-energy short-wave blue light with irregular frequencies brought by these screens affects our retinas. Blue light is high-energy visible light with a wavelength of 400-500nm. It can directly penetrate the cornea, eye lens, and reach the retina, stimulating the retina to produce a large number of free radical ions, causing the shrinkage of retinal pigment epithelial cells and causing the death of light-sensitive cells. The retinal pigment epithelial cells have a strong absorption effect on the light radiation in the blue ...
