Document Type and Number:
WIPO Patent Application WO/2022/213763
Kind Code:
A1
Abstract:
An anti-blue-light resin lens having ultra-low reflection and a clear base color, and a preparation method therefor. The resin lens comprises a resin lens substrate (1), a hardened layer (2), an anti-blue-light film layer (3) having ultra-low reflection and a clear base color, and a waterproof layer (4), wherein the resin lens substrate (1), the hardened layer (2) and the anti-blue-light film layer (3) having ultra-low reflection and a clear base color are arranged in sequence; the hardened layer (2) is located on the surface of the resin lens substrate (1), and the anti-blue-light film layer (3) having ultra-low reflection and a clear base color is located on the surface of the hardened layer (2); and the anti-blue-light film layer (3) having ultra-low reflection and a clear base color is composed of a high-refractive-index material, i.e. a titanium-niobium composite oxide, and a low-refractive-index material, i.e. a silicon-aluminum composite oxide.
