Abstract

Contact lenses comprising designs/colorants may be utilized to enhance and/or highlight the appearance of the eyes upon which the contact lenses are positioned. These contact lenses comprise a substantially annular shaped clear layer on the front curve surface to completely encapsulate the designs/colorants within the contact lens. The annular shape provides no clear coat over the optic region thereby ensuring high optical quality.

First claim

What is claimed is:

1 . A cosmetic contact lens, the cosmetic contact lens comprising:
an annular shaped clear coat layer formed from a first material; one or more effect layers affixed to the annular shaped clear coat layer; and bulk lens material covering and surrounding both the annular shaped clear coat layer and the one or more effect layers.

2 . The cosmetic contact lens according to claim 1 , wherein the annular shaped clear coat layer comprises a first annular section, a transition section and an optic area opening section.

3 . The cosmetic contact lens according to claim 2 , wherein the transition section comprises a thickness gradient that decreases from the first annular section to the optic area opening section.

4 . The cosmetic contact lens according to claim 2 , wherein the transition section comprises a pattern.

5 . The cosmetic contact lens according to claim 4 , wherein the pattern comprises a geometric pattern.

6 . The cosmetic contact lens according to claim 4 , wherein the pattern comprises a dot matrix pattern.

7 . The cosmetic contact lens according to claim 4 , wherein the pattern comprise a dithering pattern.

8 . The cosmetic contact lens according to claim 4 , wherein the pattern comprises a higher density of features proximate the first annular section that diminishes to a lower density of features proximate the optic area opening.

9 . A contact lens, the contact lens comprising:
a front curve surface formed from a first material; a back curve surface formed from the first material; and an annular shaped layer formed from a second material and affixed to at least one of the front and back curve surfaces, the annular shaped layer comprising a first annular section, a transition section and an optic area opening section.
