Benefits of technology

The present invention provides a color-enhancing ophthalmic spectacle lens that enhances color separation between blue and green colors while maintaining or increasing color definition with the use of transitional metal oxides, rare-earth metal oxides, and / or organic dyes. The lens absorbs more high-frequency visible light than other inventions in its field, while maintaining or increasing color definition with the use of polarizing filters. The lens system enhances color separation between blue and yellow colors while also enhancing visibility for people fishing for yellow and blue fish. The lens uses a wavelength-selective function to attenuate cyan colors while also transmitting blue and green light. The lens may also include mirror coatings and / or anti-reflection coatings.

Problems solved by technology

Such a product is unsuited for making ophthalmic spectacle lenses.

Abstract

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).
