| titleOfInvention | POLYSILOXANE CONTACT LENS WITH GLASS COATING |
| abstract | A glass coated polysiloxane contact lens is disclosed. The substrate of the contact lens is constituted by a polymer formed by a poly (organosiloxane) linked at its terminations through a divalent hydrocarbon group to a polymerized activated unsaturated group. The glass coating is a substantially colorless transparent glass and is approximately 100 to 8,000 angstroms thick. It can be silicate, phosphate, germanate glass or mixtures thereof. The resulting contact lens is flexible, hydrophilic, and has a sufficient degree of oxygen transfer capacity to meet the needs of the human cornea. It is further wettable, free of charge, stable to hydrolysis, biologically inert, transparent, elastic and soft. The invention also relates to a method for producing such a glass-coated siloxane contact lens. |
