Abstract
A colored contact lens comprising a generally uncolored pupil region, a generally annular-shaped iris region and a multicolored pattern on the iris region. The multicolored pattern is sufficiently colored to change the apparent color of an iris of a person wearing the contact lens and comprises a plurality of color elements. The lens further comprises more than 1000 discrete generally uncolored regions defined by the color elements. At least 1000 of the discrete generally uncolored regions are sufficiently small such that an ordinary viewer viewing the contact lens from a distance of sixteen inches cannot detect the presence of any of the at least 1000 generally uncolored regions when the wearer is wearing the contact lens.
