CONTACT LENS |
摘要 |
This invention is directed to ophthalmic materials and ophthalmic lenses tha t are a co-polymerization product of a (a) hydrophilic monomer with (b) a tris(siloxy)silyl group-containing monomer, (c) a wide variety of hydrophobi c 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. |
