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.
Claims18
A contact lens that, when worn by a wearer, displays color to an observer of the contact lens, which comprises:
- a contact lens having an inner surface adapted to be placed against the eye of a wearer and an outer surface bearing a cosmetic holographic optical diffraction (CHOD) grating that, when worn by a wearer, displays color to an observer of the contact lens.
A method for a wearer of contact lens to change eye colors, which comprises:
- placing contact lens over the wearer's eye, wherein said 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 (CHOD) grating that, when worn by a wearer, displays color to an observer of the contact lens.
A method for making a contact lens, which displays a color to an observer of said contact lens having an inner surface and an outer surface, which comprises:
- applying a cosmetic holographic optical diffraction (CHOD) grating to the contact lens outer surface, so that, when worn by a wearer, said contact lens displays color to an observer of the contact lens.
