Abstract
A process for manufacturing colored contact lenses and the lens manufactured by the process. A transparent contact lens having a central pupil section and a surrounding iris section has a colorant applied in a pattern to the entire iris section such that at least about ten percent of surface of the iris section is covered by colorant. The produced lens is capable of coloring the iris of the wearer, yet permits 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.
