Abstract
The invention is generally related to a soft contact lens which comprises a hydrogel lens body and a coating of a hydrophilic copolymer thereon and to a method for producing the same. The hydrogel lens body comprises or is made of a polymeric material having 1,2- and/or 1,3-diol moieties, and the hydrophilic copolymer comprises arylborono-containing repeating units each having a boronic acid group. The coating is covalently-attached to the hydrogel lens body through cyclic boronic ester linkages each formed between one boronic acid group and one 1,2-diol or 1,3-diol group. The soft contact lens has a surface lubricity higher than the surface lubricity of the lens body.
