Problems solved by technology

However, due to the weak weather resistance of organic dyes, they will fade after long-term sunlight exposure and cannot be durable
In addition, the blue light transmission rate of many lenses is less than 10%, which is further absorbed by the lens and vitreous body in the eye. After wearing such high anti-blue light glasses, the amount of blue light that actually reaches the retina of the human eye is almost zero, that is, it completely blocks colored light. The blue light in the three primary colors (red, green, blue) will result in severe distortion of the picture. If thing...

Abstract

The invention relates to a blue light cut nano compound resin material and lens and a manufacturing method thereof. The blue light cut nano compound resin material comprises macromolecule resin as well as core-shell type transition metal oxide nano particles and an ultraviolet light absorber which are dispersed in the macromolecule resin, wherein the core-shell type transition metal oxide nano particles account for 0.2-2% of the total weight of the resin, and the ultraviolet light absorber accounts for 0.5-5% of the total weight of the resin; particle size of nano particles is 20-50nm; the shell is a surface active agent, and thickness is 3-10nm; the nano particles and the ultraviolet light absorber are fully dispersed in a macromolecule monomer, and a prepolymerization and secondary polymerization technological process is carried out, so that the blue light cut compound resin material is obtained. The manufacturing method of the blue light cut compound resin material is simple in technology and good in reproducibility, the manufactured resin material and lens can efficiently and permanently shield high energy harmful blue light and ultraviolet light with wavelength within the range of 380-450nm, vision is clear and colour vision is soft under strong and weak light environments respectively, and the blue light cut compound resin material has excellent overall performance.

Description

technical field [0001] The invention relates to an optical material, a lens and a preparation method thereof, in particular to an anti-blue light nanocomposite resin material, a lens and a preparation method thereof. Background technique [0002] As we all know, ultraviolet rays have a strong damaging effect on the eyes. Long-term exposure of the eyes to ultraviolet rays can easily cause cataracts, damage retinal pigment epithelial cells, and even accelerate age-related macular degeneration. In addition, studies have shown that blue light in visible light (short-wave light with a wavelength in the range of 380-500nm) can penetrate the lens to reach the retina, and the retina will generate free radicals after long-term exposure to blue light, and these free radicals will lead to the decline of retinal pigment epithelial cells, This in turn leads to a lack of nutrients for the light-sensitive cells, eventually causing visual impairment. And the degree of damage increases rap...
