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

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

a poly component, wherein the poly component 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;

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, wherein the poly component and the solvent are present in an amount of from about 90 to about 99.9 wt. % of a total composition comprising the poly component, the solvent, and the fluorinated material, in a ratio of 30;

70 poly component;

solvent and wherein the fluorinated material comprises a fluorinated surfactant selected from the group consisting of 1,1,2,2-tetrahydroperfluoro-1-alkanols of chain length C₆-C₁₈, 2-(perfluoroalkyl)ethyl stearate, triperfluoroalkyl citrate, 2-(perfluoroalkyl)ethanol and/or mixtures thereof.

2. The coating composition of claim 1, wherein the polysiloxane comprises a material selected from the group consisting of polysiloxanes having amino functional groups, polysiloxanes having epoxy functional groups, linear siloxanes, and cyclic siloxanes.

3. The coating composition of claim 1, wherein the fluorinated material is present in the total composition in an amount of from about 0.1 to about 10 wt. % of the total composition.
