Light orange ultra-clear ground color anti-blue light resin lens and preparation method thereof

Abstract

The invention provides a light orange ultra-clear ground color anti-blue light resin lens and a preparation method thereof. The light orange ultra-clear ground color anti-blue light resin lens comprises a resin lens substrate, a hardening layer, a light orange ultra-clear ground color anti-reflection film layer and a waterproof layer, wherein the substrate, the hardening layer and the light orange ultra-clear ground color anti-reflection film layer are arranged in sequence, the hardening layer is located on the surface of the resin lens substrate, and the anti-reflection layer is located on the surface of the hardening layer; the antireflection layer is composed of a high-refractive-index material titanium niobium composite oxide and a low-refractive-index material boron-doped silicon aluminum composite oxide. By adjusting the structure of the light orange ultra-clear ground color anti-reflection film layer and a proper process, the anti-blue-light resin lens with a particularly clear visual effect, namely an extremely low yellow index, is obtained, the high temperature resistance and the environment resistance of the resin lens are greatly improved, and particularly, the resin lens is not easy to generate damp spots in a humid environment and has a good application prospect. And the light orange film color makes human eyes feel comfortable, and has a good market application prospect.

Description

technical field [0001] The invention relates to the technical field of resin lens preparation, in particular to a light orange ultra-clear background anti-blue light resin lens and a preparation method thereof. Background technique [0002] In recent years, the demand for optical resin lenses in the domestic and foreign glasses market has been increasing. Compared with glass lenses, resin lenses have the advantages of light weight, good dyeing performance, and easy processing. Medium and high refractive index optical resin lenses are more transparent. The unique advantages of high efficiency, UV protection, ultra-thin and so on are favored by users. Usually in the lens industry, a lens with a refractive index of 1.60 or more is a high refractive index, a refractive index of 1.56 is a medium refractive index, and a refractive index below 1.56 is a low refractive index. In order to meet the requirements of the optical performance of the resin lens, the surface of the resin le...

Problems solved by technology

[0004] At present, the anti-blue light resin lenses on the market often have a yellowish base color. This is because the anti-blue light itself will cause the visual yellowish. In order to maintain the anti-blue light characteristics and achieve a clear background color, we urgently need to provide a light orange color. Ultra-clear background, anti-blue light, high temperature and durable resin lens
