Official abstract text for this publication.
Pearlescent pigments may be incorporated into one or more regions of a cosmetic contact lens to add a shiny, radiant and iridescent appearance thereto. More particularly, mica based pearlescent pigments coated with an oxide, for example, titanium dioxide or iron oxide, incorporated into one or more regions of the contact lens will result in the one or more regions having a natural, wet reflective appearance.
Opening claim text (preview).
What is claimed is: 1. A contact lens, the contact lens comprising: a clear pupil section in the center of the lens and designed to overly a wearer's pupil; a first region corresponding to and designed to overly the scleral portion of a wearer's eye, the first region including a bright color incorporated therein; a second region corresponding to and designed to overly the iris portion of a wearer's eye, the second region being inside of the first region, surrounding the clear pupil, and having an annular shape; and mica based pearlescent pigments incorporated solely in the first region which overlays the scleral portion of the wearer's eye, the mica based pigments in combination with the bright color giving that region a shiny, radiant and iridescent appearance, the mica based pearlescent pigments being encapsulated within the material forming the lens. 2. The contact lens according to claim 1 , wherein the mica based pearlescent pigment are coated with an oxide layer. 3. The contact lens according to claim 2 , wherein the oxide layer comprises titanium dioxide. 4. The contact lens according to claim 2 , wherein the oxide layer comprises iron oxide. 5. The contact lens according to claim 1 , wherein the mica based pearlescent pigments comprise potassium aluminum silicate. 6. The contact lens according to claim 1 , wherein the mica based pearlescent pigments are arranged in a random pattern. 7. The contact lens according to claim 1 , wherein the mica based pearlescent pigments are arranged in a non-random pattern. 8. The contact lens according to claim 1 , wherein the mica based pearlescent pigments encapsulated with the first region. 9. The contact lens according to claim 1 , further comprising one or more non-mica based pearlescent pigments to be combined with the mica based pearlescent pigments. 10. The contact lens according to claim 1 , further comprising one or more non-pearlescent pigments to be combined with the mica based pearlescent pigments. 11. The contact lens according to claim 1 , further comprising one or more dyes to be combined with the mica based pearlescent pigments.
