Ophthalmic lenses, ophthalmic lens coating compositions, and methods for manufacturing ophthalmic lenses

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.

A method for forming an ophthalmic lens, the method comprising the steps of:

• providing a polymeric lens;
• preparing a coating composition, 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;
• applying the coating composition to the polymeric lens;
• evaporating the solvent;
• subjecting the polymeric lens to a thermal treatment after evaporating the solvent to cure the polysiloxane, the polyurethane, the oligomer derived from a polysiloxane or a polyurethane, the polymer derived from a polysiloxane or a polyurethane, or the combination thereof.
