An ophthalmic spectacle lens having
transmittance properties that block UV and
violet light and partially block certain cyan wavelengths to enhance contrast between blue versus green and partially block certain yellow wavelengths to enhance contrast between green versus red, and keep in accordance with the tristimulus values. Adding
wavelength-selective organic dyes provides the entire functional attributes of the current invention or improves the contrast-enhancing attributes provided by a glass
wafer having functional rare-earth oxides, either of which improve multi-
band spectrum that is balanced in blocking UV light, and adding contrast between the primary colors to optimize color-enhancing functions. When using organic dyes for all functional attributes it is possible to integrate these dyes into plastic ophthalmic materials. Some lenses are polarized. Unlike other color-enhancing sunglass lenses, this invention may help protect the eyes from over-
exposure to some high-energy visible
blue light, which may lead to age-related
macular degeneration (AMD).
