Abstract

Ophthalmic lenses, coatings for ophthalmic lenses, and methods for manufacturing ophthalmic lenses are provided herein. In one exemplary embodiment, an ophthalmic lens comprising a polymeric lens has a first surface and second surface. A coating overlies the first surface. The coating comprises a polysiloxane, a polyurethane, an oligomer derived from a polysiloxane or a polyurethane, a polymer derived from a polysiloxane or a polyurethane, or a combination thereof, and a fluorinated material. The coating exhibits a water contact angle of greater than 90° as measured by a goniometer.

Claims

a polymeric lens having a first surface and second surface;

a coating overlying the first surface, the coating comprising;

a polysiloxane, a polyurethane, an oligomer derived from a polysiloxane or a polyurethane, a polymer derived from a polysiloxane or a polyurethane, or a combination thereof; and

a fluorinated material,

wherein the coating exhibits a water contact angle of greater than 90°

as measured goniometer.

2. The ophthalmic lens of claim 1, wherein the polymeric lens comprises a polymer selected from the group consisting of allyl diglycol carbonate, bisphenol A polycarbonate, and poly(methylmethacrylate).

4. The ophthalmic lens of claim 1, wherein the polysiloxane comprises a material selected from the group consisting of aminosilanes, epoxysilanes, linear siloxanes, and cyclic siloxanes.

5. The ophthalmic lens of claim 1, wherein the fluorinated material comprises a fluorosurfactant polyol.

6. The ophthalmic lens of claim 1, wherein the fluorinated material comprises a fluorinated hydrocarbon silane.

7. The ophthalmic lens of claim 6, wherein the fluorinated hydrocarbon silane comprises a material selected from the group consisting of nonafluorohexyltrimethoxysilane, nonafluorohexyltriethoxysilane, and (tridecafluoro-1,1,2,2-tetrahydrooctyl)triethoxysilane.

8. The ophthalmic lens of claim 1, wherein the fluorinated material comprises a fluorinated solvent.

9. The ophthalmic lens of claim 8, wherein the fluorinated solvent comprises a material selected from the group consisting of methoxy-nonafluorobutane, 1,1,2,2,3,3,4-heptafluorocyclopentane, perfluorohexane, and 1,1,1,2,3,4,4,5,5,5-decafluropentane.

10. A coating composition for an ophthalmic polymeric lens, the coating composition comprising:

a polysiloxane, a polyurethane, an oligomer derived from a polysiloxane or a polyurethane, a polymer derived from a polysiloxane or a polyurethane, or a combination thereof;

a solvent; and

a fluorinated material,

wherein a thermally cured coating resulting from the coating composition exhibits a water contact angle of greater than 90°

as measured by a goniometer when applied in a single coat on the ophthalmic polymeric lens.

11. The coating composition of claim 10, wherein the polysiloxane comprises a material selected from the group consisting of aminosilanes, epoxysilanes, linear siloxanes, and cyclic siloxanes.

12. The coating composition of claim 10, wherein the fluorinated material comprises a fluorosurfactant polyol.
