Problems solved by technology

Existing anti-blue light lenses reflect almost all blue-violet light and completely block blue light in the three primary colors of colored light, while traditional coating technology only has a blue light blocking rate of 5-10%, and long-term wear cannot greatly reduce blue light eye hazard

Abstract

The invention discloses an anti-blue-ray resin composition, which comprises the following components in parts by weight: 60-84 parts of matrix resin, 1.5-3.5 parts of melanin nanoparticles, 1-4 partsof a UV absorbent, 2-5 parts of polyvinylpyrrolidone, 3-6 parts of allyl alcohol, 0.5-1.4 parts of calcium hydroxide and 0.7-1.5 parts of potassium carbonate. The preparation reaction conditions of the resin composition are mild, no pollution is caused, and the cost is low; the melanin nanoparticles are introduced into the resin composition, so that the original color of the color is not lost while a certain proportion of blue light is absorbed; besides, in the preparation process of the resin, the melanin nanoparticles are compounded with polyvinylpyrrolidone, so that the dispersity of the melanin nanoparticles in the resin composition can be greatly improved, the effective area for absorbing blue light is larger, and the melanin nanoparticles are promoted to play a better blue light absorption role in the resin composition.

Description

technical field [0001] The invention relates to an anti-blue light resin composition and a preparation method thereof. Background technique [0002] optical resin [0003] With the progress and development of modern society, products such as LED lights, TVs, computer screens, smart phones, and tablet computers have been widely used in all aspects of people's lives. The light emitted by these products contains a large number of high-energy short-wave irregular frequencies. Blue light, and the energy of short-wavelength blue light is much stronger than green, yellow, and red light. It will directly penetrate the cornea and reach the retina, causing the retina to produce free radicals. Free radicals lead to the death of retinal pigment epithelial cells, and then make the photosensitive cells lack nutrients and cause visual impairment. Macular degeneration occurs, squeezing and shrinking the lens, causing myopia and even macular degeneration. [0004] Wearing anti-blue light g...
