Problems solved by technology

Inorganic materials are often used as optical anti-reflection film materials, but due to the differences in the physical and chemical properties of the polymer resin lens substrate and the inorganic material film layer, the stress of the finished lens is high, resulting in poor temperature and environment resistance; Poor temperature resistance itself limits its better use effect

Abstract

The invention provides a low-reflection-color neutral low-stress resin lens and a preparation method thereof. The low-reflection-color neutral low-stress resin lens comprises a resin lens substrate, ahardening layer and an antireflection layer, wherein the substrate, the hardening layer and the antireflection layer are sequentially arranged, the hardening layer is located on the surface of the resin lens substrate, and the antireflection layer is located on the surface of the hardening layer; the antireflection layer is mainly formed by alternately arranging niobium-titanium composite oxide (composed of Nb2O5 and TiO2, wherein the Nb2O5 accounts for 75%-95% of the molar fraction of the material) layers and low-refractive-index material layers, namely, special low-stress SiO2 film layers.By adjusting the structure of the antireflection layer, the resin lens meeting the antireflection rate is obtained, and meanwhile, a color neutral lens product with a good visual effect is obtained. By strictly controlling the material composition and the preparation process, the temperature resistance and the environmental resistance of the resin lens for preparing glasses are greatly improved, and the resin lens has good application and market prospects.

Description

technical field [0001] The invention relates to the technical field of resin lens preparation, in particular to a resin lens with low reflection, color, neutrality and low stress and a preparation method thereof. Background technique [0002] In recent years, the demand for optical resin lenses in the domestic and foreign glasses markets 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 High efficiency, UV protection, ultra-thin and other unique advantages are favored by users. [0003] Generally, in the lens industry, a lens with a refractive index above 1.60 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. There are many factors that affect the refractive index of the lens. Due to the structural difference of ...
