Abstract

The present invention recognizes that lenses, such as contact lenses, can be pigmented using ink that include polymers or polymerizable monomers, preferably the same monomers used to make the lens. Preferably, such lenses are made using bonding agents. The ink can be used to make images on or within the lens. Images made using these inks are preferably digital and can be used in a variety of printing methods, including ink-jet printing.
