Abstract:
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 C 6 -C 18 , 2-(perfluoroalkyl)ethyl stearate, triperfluoroalkyl citrate, 2-(perfluoroalkyl)ethanol and/or mixtures thereof.
