  • Opthalmic lenses having reduced base out prism
    Patent number: 8287124
    Abstract: The invention generally relates to a lens and the method of manufacturing progressive addition lenses (PAL) to remove unwanted base out prism and minimize excessive convergence, comprising determining basic configuration of two major lens surfaces to provide a distance portion and near portion, wherein diopter power increases from the distance portion of the lens to the near portion; selecting an amount of prism reduction; and reducing base out prism that inherently occurs as diopter power increases by altering the configuration of the lens as a function of the amount of prism reduction to minimize any disruption of optical properties a lens while decreasing base out prism.
    Type: Grant
    Filed: August 22, 2011
    Date of Patent: October 16, 2012
    Assignee: Crossbows Optical Limited
    Inventors: Jeffrey P. Krall, Hugh McLoughlin, Trevor Steele, Andrew Whale
