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, wherein the annular shaped clear coat layer comprises a first annular section, a transition section and an optic area opening section, the optic opening area being free of the first material and the transition section being thinner proximate the optic area opening section with a thickness of about 10 microns and thicker proximate the first annular section with a thickness of about 20 microns;
one or more effect layers; and
bulk lens material, the one or more effect layers being encapsulated between the annular shaped clear coat layer and the bulk lens material with the bulk lens material filling the optic area opening.

2. The cosmetic contact lens according to claim 1 , wherein the transition section comprises a pattern.

3. The cosmetic contact lens according to claim 2 , wherein the pattern comprises a geometric pattern.

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

5. The cosmetic contact lens according to claim 2 , wherein the pattern comprise a dithering pattern.

6. The cosmetic contact lens according to claim 2 , 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.
