Abstract
An apparatus for disinfecting lenses includes a single hand-held case with a lens compartment and a power supply compartment. A battery powered unit disposed within the power supply compartment responds to activation of a switch on the case to generate an electric current which is coupled to a pair of electrodes within the lens compartment to electrolyte a solution in the lens compartment and thereby disinfect lenses submerged in the solution. Disinfecting proceeds using a buffered solution to retain solution pH within predefined limits while enabling electrolysis with a large current of shorter duration to decreased disinfecting time. A lip circumscribing an upper opening of the lens compartment is covered with a single hinged cover member that lifts directly away from the lip, and a slidable retainer member is used to retain the cover member in a closed position. Ribs on the cover member retain the lenses submerged in the solution, and a hydrophobic element discharges gases produced by electrolysis. An enlarged ruthenium coated anode enhances electrolytic action while inhibiting catalytic degradation, while timing circuitry and indicators on the case enhance operator convenience.
