Abstract
A contact lens has an inner surface adapted to be placed against the eye of a wearer and an outer surface bearing a cosmetic holographic optical diffraction grating that, when worn by a wearer, displays color to an observer of the contact lens. The holographic optical diffraction grating can diffract incident light to display one or more colors to the observer, or can be formed as an alphanumeric character(s) or graphic display to the observer.
