Abstract

The invention provides an anti-blue light nanometer composite monomer material and anti-blue light optical resin prepared from the anti-blue light nanometer composite monomer material. The monomer material comprises a macromolecular monomer, core-shell type transition metallic oxide nanoparticles dispersed in the macromolecular monomer and an ultraviolet absorbent, wherein the total quantity of the nanoparticles accounts for 0.2%-2% of the total weight of the monomer, and the total quantity of the ultraviolet absorbent accounts for 0.5%-5% of the total weight of the monomer; the particle sizes of the nanoparticles are 20-50nm; and a shell is a surface active agent, and the thickness of the shell is 3-10nm. The anti-blue light nanometer composite monomer material can be used for preparing the high-performance anti-blue light nanometer composite optical resin material through a conventional polymerization technology; and the high-performance anti-blue light nanometer composite optical resin material can be used for efficiently and durably shielding high-energy harmful blue light and ultraviolet light with wavelengths of 380-450nm, has excellent combination properties and can be widely applied to the fields of optical protective materials such as blue light protection lenses, LED (Light Emitting Diode) display screen protective films, LED lamp protective films, automobile lamps and optical protective glass.

Description

technical field [0001] The invention relates to an optical monomer and a resin material, especially an anti-blue light nanocomposite monomer and a resin material 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...

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
