Abstract:
1. A colored contact lens comprising: a generally uncolored pupil region; a generally annular-shaped iris region surrounding the pupil region and adapted to cover at least 80% of a wearer's iris when the wearer is wearing the contact lens; and a multicolored pattern on the iris region, the multicolored pattern being sufficiently colored to change the apparent color of an iris of a person wearing the contact lens, the multicolored pattern comprising a plurality of color elements; more than 1000 discrete generally uncolored regions being defined by the color elements, at least 1000 of the discrete generally uncolored regions being 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, the ordinary viewer having 20/20 vision.
