Abstract: A colored contact lens (10) having a non-opaque pupil section (20), an iris section (22) surrounding the pupil section (20), and a colored, opaque intermittent pattern made up of a plurality of elements located over the entire iris section (22) that leaves a substantial portion within the interstices of the pattern non-opaque, the pattern covering an effective amount of the iris section (22) to change the apparent color of the iris, the pattern having a plurality of portions, each of the portions being a different shade from each other portion, each of the portions overlapping each other portion at a plurality of points, where at least one of the plurality of portions contains a design, thereby providing a lens (10) capable of changing the apparent color of the iris of a person wearing the lens (10) and imparting a very natural appearance.

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.

Abstract: A colored contact lens comprising a non-opaque pupil section, an iris section surrounding the pupil section. A colored, opaque, intermittent pattern is deposited over the iris section using opaque elements which are indiscernible to the ordinary viewer. The elements of the pattern are of a shade which provides a contact lens capable of making subtle changes or enhancements to the color of the iris of a dark-eyed person while imparting a very natural appearance.

Abstract: Adding a small quantity of a violet colorant to a contact lens material provides a clear contact lens that has no apparent undesirable yellow tint, such as caused by a UV-absorbing compound. Further, the violet colorant can also be used with a colored lens, in the absence of the handling tint, to mask any undesirable yellow tint, such as that produced by a UV-absorbing compound. The violet colorant will not unacceptably alter the modifying color of the colored lens.

Abstract: A system is provided for producing a high contrast image of features of an optical component. In the system of the present invention, light is focused through the optical component prior to reaching the detector of an image sensing means.

Abstract: A system is provided for producing a high contrast image of features of an optical component. In the system of the present invention, light is focused through the optical component prior to reaching the detector of an image sensing means. In addition, a novel cuvette is provided for holding and locating an optical component in position during inspection. The cuvette comprises a bottom portion having a concave curved inner surface for utilizing the force of gravity to hold an optical component in place.

Abstract: A contact lens with enhanced UV blocking to meet ANSI Class 1 specifications includes enhanced effective amounts of two different UV absorbing compounds. One UV absorber is a benzotriazole derivative, and the other UV absorber is a benzophenone derivative.

Abstract: Contact lenses, intraocular lenses and transparent plastic with enhanced UV blocking to meet ANSI Class 1 specifications include enhanced effective amounts of two different UV absorbing compounds. One UV absorber is a benzotriazole derivative, and the other UV absorber is a benzophenone derivative. The lenses are made from a polymer that incorporates both of these UV absorbers.

Abstract: A contact lens and method for making the same provides a cosmetic effect using pearlescent pigment.

Abstract: An automatic system for inspecting contact lenses that are suspended in a saline solution within a lens holder. In the manufacturing process a first electronic image is taken of each lens disposed in its holder. Thereafter a second image is taken of the lens after the holder has been rotated and the solution and lens have moved. The two images are compared and any dark spots on the first image that move with respect to the second image are eliminated as artifacts that are caused by contaminants in the solution or marks on the lens holder. The rim of the lens, optical zone, printed logo and colored iris area of the lens are automatically inspected by a computer program for defects. The lens is rejected if defect features are found in any of the inspected areas.

Abstract: A colored contact lens comprising a non-opaque pupil section, an iris section surrounding the pupil section, and a colored, opaque, intermittent patter over the iris section. The pattern having elements which are indiscernible to the ordinary viewer. The elements of the pattern are a color which provides a contact lens capable of making change or modifications to the appearance of the color of the iris to a striking olive green color, while importing a very natural appearance.

Abstract: A contact lens comprising an optically transparent lens body having a concave surface adapted to the patient's eye curvature and a convex surface. The lens has three regions: (1) an annular region of a first optical power; (2) at the center of said annular region, which is also at the optical center of said lens, a substantially pinhole-like aperture; and (3) a second larger annular region exterior to the first annular region.
