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, taking lens materials as an example, the blue light transmission rate of many lenses made of anti-blue light resin is less than 10%. After further absorption by the lens and vitreous body in the eye, the blue light actually reaches the retina of the human eye after wearing such high anti-blue light glasses. The amount of blue light is almost zero, that is, the blue color light in the three primary colors of color light (red, green, and blue) is completely blocked, which will cause severe distortion of the picture, and in the long run will reduce the color sensitivity of the optic nerve, which may lead to color weakness or even color blindness.
Not only that, the selective transmittance of colored anti-blue light lenses to long-wave visible light is low, and the ability to see objects and color discrimination is weak when worn, especially in cloudy or low-light environments. The consistent and effective improvement methods adopted at this stage are Evaporation of 3-11 or more layers of anti-reflection film, the manufacturing process is complicated and the anti-reflection effect is limited

Abstract

The invention discloses anti-blue ray optical resin. The anti-blue ray optical resin comprises an acrylate macromolecule monomer for manufacturing an optical material, modified metallic oxide nanometer particles, an ultraviolet light absorbent and an initiating agent, wherein the modified metallic oxide nanometer particles are 1-5wt% of the acrylic macromolecule monomer; the ultraviolet light absorbent is 0.2-2wt% of the acrylic macromolecule monomer; and the initiator is 0.1-0.5wt% of the acrylic macromolecule monomer. The anti-blue ray optical resin can shield high-energy harmful blue rays and ultraviolet rays with the wavelength in the range of 380 to 450 nm effectively and endurably, and has a good comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of optical resins, in particular to an anti-blue light optical resin 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 rapidly as the wavelength of light decreases. Bl...
