Printing colored contact lenses
摘要:
A method of making a colored contact lens comprises printing at least one layer of a colorant onto a contact lens using a printing process selected from the group consisting of ink jet printing, electrophotographic printing, thermal transfer printing, and photographic development printing. Printing can be done directly on the contact lens, on a film in a mold where the contact lens is formed, or on a cliché pad. Multiple layers of colorants can be printed onto a contact lens.
