This invention is directed to ophthalmic materials and ophthalmic lenses that are a co-polymerization product of a (a) hydrophilic monomer with (b) a tris(siloxy)silyl group-containing monomer, (c) a wide variety of hydrophobic monomers (both aliphatic and aromatic) and usually a (d) polyfluorinated monomer, as well as optional monomers or monomer mixtures that can include a cationic monomer, a non-aromatic hydrophobic monomer and a poly(dimethylsiloxy)silyl group-containing monomer. A contact lens prepared from such a co-polymer exhibits enhanced water content, while maintaining exceptional oxygen permeability, thereby providing a lens that can be worn comfortably for prolonged periods of time. A process for the preparation of such lenses is also disclosed.

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 clichà pad. Multiple layers of colorants can be printed onto a contact lens.

A method comprises the steps of (a) providing a water based ink in at least one cliché with a contact lens pattern; (b) transferring the water based ink from the cliché to at least a surface of at least a contact lens forming mold by means of at least a transfer pad; (c) at least partially curing the ink transferred on the mold to form a colored film; (d) dispensing a hydrogel lens-forming material into a lens-forming cavity of the mold; and (e) curing the lens-forming material within the lens-forming cavity to form the contact lens, whereby the colored film detaches from the molding surface and becomes integral with the body of the contact lens; characterized in that the relative air humidity in the immediate vicinities of the transfer pad/s is kept higher than 50% at standard temperature and pressure conditions during ink transfer.
