Abstract
A colored contact lens including a non-opaque pupil region and a generally annular-shaped iris region surrounding the pupil region. The iris region is adapted to cover some of a wearer's iris when the wearer is wearing the contact lens and includes at least one pattern formed by an arrangement of discrete color elements having varying sizes. Typically, two or more patterns formed by the discrete color elements are overlaid on each other to form the iris region and give the iris region a more tonal and natural appearance.
