The present invention is directed to new and improved packaging systems for storing ophthalmic devices such as contact lenses and to methods for packaging such ophthalmic devices with aqueous packaging solutions to improve the comfort of the lens during wear. In particular, the present invention is directed to a packaging system for storing an ophthalmic device in an aqueous packaging solution comprising an anionic polymer and a non-ionic polyol. Such solutions can be retained on the surface of an unused lens for extended periods of time, resulting in surface modification that persists in the eye, which may provide significant improvement in the wetting properties of fresh contact lenses used for the first time and, moreover, even several hours after lens insertion, preventing dryness and improving lubricity.
