  • Ophthalmic lens comprising lenslets for preventing and/or slowing myopia progression
    Patent number: 11061255
    Abstract: Contact lenses incorporating an array of non-coaxial lenslets with add power that create non-coaxial myopic defocus within the optic zone of the lens may be utilized to prevent and/or slow myopia progression. The positive, non-coaxial lenslets cover about twenty to eighty percent of the central pupil area to deliver positive foci of light in front of the retina to slow the rate of myopia progression.
    Type: Grant
    Filed: May 30, 2018
    Date of Patent: July 13, 2021
    Assignee: Johnson & Johnson Vision Care, Inc.
    Inventors: Manwai Charis Lau, Noel Brennan, Khaled Chehab, Xu Cheng, Michael Collins, Brett Davis, Eric R. Ritchey, Fan Yi
  • HIGH PLUS TREATMENT ZONE LENS DESIGN AND METHOD FOR PREVENTING AND/OR SLOWING MYOPIA PROGRESSION
    Publication number: 20210033889
    Abstract: Contact lenses incorporate high plus or add power profiles that at least one of slow, retard or preventing myopia progression and minimize halo effect. The lens includes a center zone with a negative power for myopic vision correction; and at least one treatment zone surrounding the center zone, the at least one treatment zone having a power profile that increases from an outer margin of the center zone to a positive power within the at least one treatment zone of greater than +5.00D.
