  • Optical lenses with selective transmissivity functions
    Patent number: 4952046
    Abstract: An opthalmic spectacle or contact sharp cut-on orange lens that improves visual acuity and substantially reduces eye damage in a bright sunlit environment. The lenses substantially eliminate ultraviolet radiation and blue light shorter than 515 nm. The ultraviolet radiation has been implicated as a cause of cateractogenisis. The blue light is implicated in senile macular degenerations, night blindness and snow blindness. The lens is substantially transparent to wavelengths greater than 636 nm which are most useful for high visual acuity in bright sunlit environment.
