A cosmetic soft contact lens which alters the apparent color of the iris by employing small light reflecting particles imbedded in a colored transparent matrix. n The lens is made in the hard state from a xerogel blank having a colored pupil area surrounded by a colored iris area having imbedded light reflecting particles. A clear peripheral area is present outside the iris area. A zerogel contact lens is made from the cosmetic blank and hydrated to form a larger soft hydrogel cosmetic contact lens. n The cosmetic contact lens serves a dual purpose to correct the visual errors and change the apparent color of the eye. The natural iris pattern is visible through the lens providing a natural appearance. |
