Abstract
Methods are disclosed for manufacturing a coated contact lens that comprises a polymeric lens body comprising an acid group, a first coating polymer comprising a first amine group ionically bound to the acid group, and a second coating bound to the first coating polymer through covalent linkage between a nitrogen atom of a second amine group on the first coating polymer and an amine-reactive group of the second coating polymer. In some examples the lenses exhibit improved surface properties compared to uncoated lenses, such as reduced adhesion, increased wettability, increased lubricity, and/or increased lipid resistance.
