  • Patent number: 6929367
    Abstract: A colored contact lens having a very natural appearance is disclosed. The inventive lens has a non-opaque pupil section and iris section that is at least partially opaque and comprised of two portions. A first portion, generally located on the outside of the iris section, has a first shade. A second portion, generally located on the inside of the iris section has a second shade. A jagged border separates the two portions. A third iris section and second jagged border are also disclosed. In some embodiments portions of the iris section may be non-opaque.

  • Publication number: 20030165015
    Abstract: Coated contact lenses are produced by providing a lens and coating at least a portion of a surface of the lens derived from a binder component and an activation component. The binder component comprises a binding polymer component with at least one epoxy group, and preferably at least two epoxy groups, per polymer molecule. The activation component is capable of reacting with the binding polymer component to form a crosslinked polymer component. Methods of coating lenses and coating compositions are also provided.

  • Publication number: 20020060777
    Abstract: A method of forming a contact lens containing a colored ring that covers a portion of or the entire limbus area of the eye when the contact lens is worn. The method of forming the contact lens includes applying a colorant material in a limbal ring pattern to the surface of a one-sided contact lens mold, then filling the one-sided contact lens mold with a polymerizable substance, casting the substance thereby forming a molded surface containing a limbal ring pattern, and machining the opposite side thereby creating a finished side opposite the molded surface.

  • Patent number: 4963159
    Abstract: There is disclosed a method for making colored hydrophilic contact lenses. A contact lens constructed of hydrophilic polymer that is substantially devoid of the functional groups --COOH, --OH, --NH--R, wherein R is hydrogen or C.sub.1 to C.sub.8 alkyl, --NCO and epoxy is provided. At least a portion of the surface of the lens is coated with a color coat comprising at least one pigment, binding polymer having functional groups selected from at least one of --COOH, --OH, and --NH--R, wherein R is hydrogen or C.sub.1 to C.sub.8 alkyl, and an additional compound having at least two groups per molecule of --NCO. The coated lens is subjected to conditions which cause the color coat to adhere to the lens.
