  • Ocular mask having selective spectral transmission
    Patent number: 10765508
    Abstract: A mask is provided that is configured to increase the depth of focus of a patient. The mask can include an aperture configured to transmit along an optical axis substantially all visible incident light. The mask can further include a portion surrounding at least a portion of the aperture. The portion may be configured to be substantially opaque to visible electromagnetic radiation and be substantially transparent to electromagnetic radiation transmitted from an ocular examination device (e.g., substantially transparent to at least some non-visible electromagnetic radiation with a wavelength between about 750 nm and about 1500 nm).
    Type: Grant
    Filed: May 24, 2019
    Date of Patent: September 8, 2020
    Assignee: AcFocus, Inc.
    Inventors: Abhiram S. Vilupuru, Marie Dvorak Christ
