Abstract
Coated contact lenses are produced by providing a lens and coating at least a portion of a surface of the lens derived from a binder component and an activation component. The binder component comprises a binding polymer component with at least one epoxy group, and preferably at least two epoxy groups, per polymer molecule. The activation component is capable of reacting with the binding polymer component to form a crosslinked polymer component. Methods of coating lenses and coating compositions are also provided.

A method for coating a lens, the method comprises the steps of:
- coating at least a portion of a surface of a lens comprising a lens polymer component with (i) a binder component comprising a binding polymer component having at least one epoxy group per polymer molecule, and (ii) an activation component effective to crosslink the binding polymer component;
- and
- causing the activation component to react with the binder component, thereby forming a coating comprising a crosslinked polymer component.
A coating composition for coating a lens comprising:
- a binder component comprising a binding polymer component having at least one epoxy group per polymer molecule;
- and
- an activation component effective to react with the binding polymer component to form a crosslinked polymer component.
A coated lens comprising:
- a lens body comprising a lens polymer component having a surface;
- and
- a coating comprising a crosslinked polymer component located on at least a portion of the surface, the coating being derived from a coating composition comprising a binder component comprising a binding polymer component having at least one epoxy group, and an activation component effective to react with the binder polymer component to form the crosslinked polymer component.
