Patent ID: 10371967

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 bonded to 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 tone remain neutral balance. The overall transmittance light spectrum has three pass-bands corresponding to the maximum response of the human eye cone cells, and the relatively high transmittance values of each pass-band center are approximately at 450 nm, 530 nm and 610 nm. The FWHM of each pass-band is between 3 nm and 50 nm.
