Abstract
An improved method for rapid disinfection of contact lenses in a convenient and reliable manner is disclosed in which a series of oxidation-reduction reactions are employed. Specifically, dichloroisocyanurate and potassium iodide react to form iodine species for disinfecting the contact lens. An amount of ascorbate is then added to neutralize the iodine species.
