Problems solved by technology

Working in the environment of strong light or heat radiation for a long time, the human eyes will feel dry and tired, and even cause eye diseases such as glaucoma and cataract; while ordinary optical glasses have no filtering effect on infrared light, even colored sunglasses filter Effective visible light is also filtered out while infrared rays are removed, so wearing colored sunglasses has the disadvantages of unclear vision and poor color discrimination performance

Abstract

The invention discloses an anti-reflection infrared-resisting coated resin lens and a preparation method thereof. The anti-reflection infrared-resisting coated resin lens comprises a lens substrate and hardening layers on the inner side and the outer side of the substrate, wherein the surfaces of the hardening layers on the inner side and the outer side of the substrate are both coated with anti-reflection infrared-resisting coatings which have a reflecting action on near-infrared light and an anti-reflection effect on visible light; the main wavelength range of the lens is 450 to 500 nm. Theanti-reflection infrared-resisting coated resin lens disclosed by the invention has the advantages that transmittance of the visible light can be improved while the transmittance of infrared light isreduced; in addition, the adhesion of the coatings can be improved so as to prevent the coatings from falling off; besides, the coatings and the process are simplified and the thickness of the lens isreduced; furthermore, the lens is attractive and diversified, so that different needs can be met. The preparation process of the anti-reflection infrared-resisting coated resin lens has the advantages of low possibility of falling off for the coatings, high sustainability and good friction resistance; post-processing of the lens is simplified, the production efficiency and the product quality areimproved and the production operation cost is reduced.

Description

technical field [0001] The invention belongs to the field of resin lenses, and more specifically relates to an anti-reflection and anti-infrared coating resin lens and a preparation method thereof. Background technique [0002] Optical resin lens is a kind of optical lens made of polymer resin material. Compared with glass lenses, it has the advantages of light weight, strong impact resistance, low cost and meeting special needs, and has been widely used. In recent years, the promotion of functional resin lenses has been recognized and welcomed by the market, especially for the protection of ultraviolet and blue light bands, because the light of these bands can easily penetrate the lens of the eye and reach the retina, rapidly accelerating the macular degeneration of the eye. Oxidation process in the region can cause great damage to the eyes, resulting in symptoms such as dry eyes, eye irritation and sore eyes, and can also cause fundus damage after cataract surgery.
