ABSTRACT:
A soft contact lens which comprises a water-swollen gel of a polymer prepared by polymerizing one or more hydrophilic monomers such as 2-hydroxyethyl methacrylate, one or more cross-linking monomers, a monomer that contains metal-chelating functionality such as an aminopolycarboxylic acid that contains a polymerizable olefinic group, and an effective amount of iron to absorb UV light and/or an effective amount of copper to cause the lens to be tinted.
