Document Type and Number:
WIPO Patent Application WO/2021/112473
Kind Code:
A1
Abstract:
The present invention relates to a polycarbonate composition and an optical product formed therefrom. The polycarbonate composition exhibits a low yellow index unlike existing yellowish blue light-blocking products, thus enabling the realization of various colors, and accordingly, optical products of various colors can be provided. Among these products, the polycarbonate composition is very suitable for use in glasses which block blue light, which is harmful to eyes, and require high transparency.
