Abstract
Provided is an eyewear lens, including a lens substrate and an optical interference coating. The lens substrate is comprised of an optical material, and the optical interference coating is combined with the lens substrate and is stacked by the composition of high and low reflectivity materials. A predefined reflective appearance color will be formed by light getting through the optical interference coating. The lens substrate contains another filter on one side surface or both side surfaces or inside the lens substrate which is complementary to the light after penetrating the optical interference coating such that the overall transmittance light color remains neutral balance. Moreover, the overall transmittance spectrum of a lens uniformly filters the reflected visible light of objects. As such, a stylish reflective appearance color lens having neutral balance perspective visual tone and most colorful rendering effect of watching the scenery is achieved.
