ABSTRACT:
An appliance for sterilizing contact lenses or the like includes a reaction vessel for containing the lenses in sterilizing contact with hydrogen peroxide solution and two catalytic elements for decomposing the hydrogen peroxide during the lens sterilization. The first catalytic element decomposes a portion of the initial concentration of hydrogen peroxide in the solution during the lens sterilization, and the second catalytic element accelerates combined decomposition of the reduced concentration of hydrogen peroxide in the solution resulting from decomposition by the first catalytic element, in order to achieve sufficiently reduced terminal hydrogen peroxide concentration at completion of the lens sterilization for safe contact by the eyes of a wearer with residues of hydrogen peroxide at the terminal concentration which may adhere to the sterilized lenses.
