Abstract
A hydrophilic contact lens is disclsoed incorporating melanin that protects the eye from harmful radiation and superoxide.
Claims41
A hydrophilic contact lens, comprising:
- a polymeric material;
- and
- a scavenging agent for scavenging a superoxide coming into contact with the scavenging agent, the scavenging agent being connected to the polymeric material.
A method of reducing damage to the eye caused by superoxide, comprising the step of scavenging the superoxide with a superoxide-scavenging agent being incorporated into a hydrophilic contact lens.
A method according to claim 14 wherein the scavenging agent is incorporated into the lattice of the lens.
A transparent and optically clear contact lens, comprising:
- a hydrophilic polymer;
- and
- a superoxide-scavenging agent attached to the polymer.
A hydrophilic contact lens, comprising a transparent filter for filtering radiation, the filter including an absorbing pigment formed from the polymerization of a melanin precursor.
A method for reducing damage to the eye caused by superoxide, comprising the step of scavenging the superoxide with a superoxide-scavenging agent being incorporated into a hydrophilic contact lens.
A transparent and optically clear contact lens, comprising a hydrophilic polymer which includes material formed from a melanin precursor.
An article of manufacture prepared by a process comprising the step of:
- applying melanin to the surface of a hydrophilic contact lens.
An article of manufacture prepared by the process comprising the step of:
- incorporating melanin into the matrix of a hydrophilic polymer.
