ABSTRACT:
A colored contact lens comprising a pupil section and an iris section. A colored, opaque, intermittent pattern is deposited over the entire iris section, but a substantial portion within the interstices of the pattern is left uncolored. The lens is capable of coloring the iris of the wearer, yet permitting visualization of the structure of the iris. A fundamental color change, e.g. from brown to blue, is possible, yet the colored iris has a natural appearance.
