  • Tinted polarized lenses having selective frequency filtering
    Patent number: 10642071
    Abstract: Tinted lenses for attenuating ambient light, reducing glare, and improving color discrimination for a user are disclosed. In some embodiments, the lens has uniform transmittance across the visible spectrum with selective filtering of light at 480 nm and 580 nm. In some embodiments, the lens may reduce light in the blue region of the spectrum while maintaining color discrimination. In some embodiments, the level of attenuation provided by the lens may vary based on the intensity of light present while maintaining selective filtering at 480 nm and 580 nm.
    Type: Grant
    Filed: February 13, 2018
    Date of Patent: May 5, 2020
    Assignee: Smith Optics, Inc.
    Inventors: Eric Carlson, Scott MacGuffie
