Abstract
A contact lens capable of causing significant changes in the color of the iris of the eye of a wearer has a first portion contacting the eye, a second portion attached to the first portion and having an upper surface capable of being tinted, and an iris portion located between the first and second portions for masking the color of the iris. The iris portion reduces or otherwise alters the reflection color of the eye and mimics the structure of the natural iris so that the tinted color becomes the dominant color when the lens is worn.
