| abstract |
The present invention recognizes that lenses, such as contact lenses, can be modified and pigmented using an ink that includes oligomers, polymers or polymerizable monomers. The ink can be used to make images on or within the lens, or the ink may be similar to the material of the lens and be precisely deposited on the lens surface to create corrective radius at the exact location on the lens surface. The lens material may also be deposited by an inkjet printer to create a hybrid lens. Deposition of ink or other material may be digital or analogue signal and can be used in a variety of printing methods, including ink-jet printing. |
