  • Methods for designing tinted contact lenses
    Patent number: 7226163
    Abstract: The invention provides a method for designing tinted contact lenses that permits the computer-assisted modeling of a tinted lens on-eye. The method of the invention provides a substantially accurate prediction as to the appearance of the lens on-eye and reduces the number of designs that must be clinically tested and the number of iterations that each design must go through.

  • Colorants for use in tinted contact lenses and methods for their production
    Publication number: 20030000028
    Abstract: The invention provides a colorant for use in tinting contact lenses in which the binding polymer used is capable of forming an interpenetrating polymer network with the lens material. When the colorants of the invention are applied to uncured lens material that is subsequently cured, the binding polymer forms an interpenetrating polymer network with the lens material embedding the colorant within the lens material resulting in a stable, tinted lens.
