发明名称 Glass coated polysiloxane contact lens
摘要 A glass coated, flexible, hydrophilic polymeric contact lens having a sufficient amount of oxygen transportability to meet the requirements of the human cornea is disclosed. In addition, this glass coated contact lens is wettable, fillerless, hydrolytically stable, biologically inert, transparent, resilient and soft. The glass coating is substantially colorless, transparent and from about 100 to about 8,000 angstroms thick. The glass may be a silicate glass, a phosphate glass or a germanate glass or mixtures thereof. The contact lens substrate comprises a polymer comprising a poly(organosiloxane) terminally bonded through a divalent hydrocarbon group to a polymerized activated unsaturated group. Further a method of making the glass coated siloxane contact lens is disclosed.
