Abstract
A scratch-resistant coating comprising a polymer including a functionalized polysilsesquioxane. The scratch-resistant coating is exposed to oxidizing conditions (e.g., ozone or ultraviolet light) that modify the surface chemistry of the coating to enhance adhesion to inorganic thin film coatings, such as antireflective coatings.
Claims37
A method of making an ophthalmic lens having a scratch-resistant coating, comprising the steps of:
- providing a polymerizable scratch-resistant coating composition comprising a polysilsesquioxane;
- polymerizing the scratch-resistant coating composition on the surface of a lens;
- and
- exposing the polymerized scratch resistant coating composition to oxidizing conditions.
A scratch resistant coating for an ophthalmic lens, comprising a polymer including a polysilsesquioxane, and wherein the coating is chemically modified by exposure to oxidizing conditions.
An ophthalmic lens, comprising:
- an optical lens;
- a scratch-resistant coating on the surface of the optical lens, comprising a polymer including a polysilsesquioxane, and wherein the surface of the scratch-resistant coating is chemically modified by exposure to oxidizing conditions;
- and
- an inorganic thin film coating on the surface of the scratch-resistant coating.
