  • System and Method for Selecting Safer Colored Ophthalmic Spectacle, Contact, Intraocular or other Lenses and Filters by Comparing the Proportion of Harmful Higher Energy Visible and Near Visible Radiation Blocked to the Light Passed by the Lens in the Photopic Region
    Publication number: 20150234180
    Abstract: A system and method for selecting safer colored ophthalmic spectacle, contact, intraocular and other lenses and filters by quantifying the amount of harmful, higher energy visible and near visible radiation blocked by it compared to the overall visible radiation passing through it is described. A figure of merit, which is produced by the method, is the Wertheim Factor, whose value is nearly 50% for lenses which block the harmful high energy radiation compared to beneficial light and is nearly 0% for lenses which pass all radiation equally. This method includes using a computer program to sample the visible and near visible transmission spectrum of said colored filter or colored ophthalmic spectacle, contact, intraocular or other lens and then evaluate the energy content of the photons present.

  • Device for imparting gradations of tint density on a plastic ophthalmic lens
    Patent number: 8397665
    Abstract: A device for imparting a curved gradation of tint density on an ophthalmic or optical lens is described. This gradient-tinting device utilizes both vertical movement and rotation about the vertical axis of the lens as it moves into a tinting solution.
