<p>Compositions and methods useful for disinfecting a contact lens are disclosed. The present methods comprise contacting a contact lens with a liquid medium containing an effective amount of an oxidative disinfectant component at conditions to effectively disinfect the contact lens. The contacting occurs in the presence of a color indicator component which is soluble in the liquid medium and is adapted to provide a color indication of the presence of the oxidative disinfectant component in the liquid medium. The color indicator component comprises an effective amount of a transition metal component which is redox active, has an oxidized state of a first color and a reduced state of a different second color and a polyanionic component in an amount effective to inhibit the staining of the contact lens by the transition metal component.</p> |
