  • Friction stabilized contact lenses
    Patent number: 11782295
    Abstract: A contact lens incorporating one or more surface modified zones on the anterior surface of the lens may be utilized to generate a friction driven rotational force when the upper and/or lower eyelids pass over the one or more regions during blinking. A small difference in the coefficient of friction between the modified and unmodified regions of the lens may result in an equivalent rotational force to that of a thickness gradient lens. This small difference in the coefficient of friction produces a means to orient and stabilize the contact lens on eye.
    Type: Grant
    Filed: July 7, 2020
    Date of Patent: October 10, 2023
    Assignee: Johnson & Johnson Vision Care, Inc.
    Inventors: Steven Franklin, Cornelis Petrus Hendriks, Gregory Hofmann, Jason Tokarski, Thom Warmerdam
