摘要： Provided is a polycarbonate composition comprising a polycarbonate and a light blocking agent, and an optical product formed therefrom. The polycarbonate composition has a low yellow index, unlike conventional yellowish blue light-blocking products, and thus various colors can be implemented. Accordingly, it is possible to provide optical products with various colors, and the polycarbonate composition is very suitable for spectacles required to have high transparency and to block blue light that is harmful to eyes.
