  • Optical lens design for flattening a through-focus curve
    Patent number: 12321044
    Abstract: Described herein are systems and/or methods for forming an ophthalmic lens. An example method may comprise a step of determining a power profile based on a power profile function defined by a base optical power, an amount of spherical aberration at a radial distance from a geometric center of the lens, and a bump function. The example method may comprise a step of adjusting the power profile based at least on minimizing a shape metric of a through-focus curve.
    Type: Grant
    Filed: October 17, 2023
    Date of Patent: June 3, 2025
    Assignee: Johnson & Johnson Vision Care, Inc.
    Inventors: Xin Wei, Philippe F. Jubin, Derek Nankivil, Minghan Chen, Gregory Williby
