Abstract
The present invention relates to contact lens solutions employing imidazole as an additive. Lenses treated with these solutions have improved resistance to protein and other polymeric depositions. The addition of imidazole to the solutions decreases the denaturalization of proteins during the cleaning cycles, and coats treated lenses to decrease the number of active binding sites.
