APPARATUS AND METHOD FOR DISINFECTING A CONTACT LENS AND DETECTING THE PRESENCE OF AN OXIDATIVE DISINFECTANT

摘要

An apparatus and method useful for disinfecting a contact lens are disclosed. The apparatus includes a color indicator element comprising an iodine component substantially irreversibly bonded to a solid material, preferably an anion exchange resin. The color indicator element is located in an oxidative disinfectant-containing liquid medium. This color indicator element provides a color indication of the presence of the oxidative disinfectant, e.g., hydrogen peroxide, in the liquid medium, and preferably a different color indication of the substantial absence of the oxidative disinfectant in the liquid medium.
