ABSTRACT:
A disinfector for heating and disinfecting contact lenses in which a main plastic housing is provided having a lens well recess from the top thereof dimensioned for receiving a standard lens carrier, and a vented lid covering the well opening. The lens well has a downwardly facing annular recess on the bottom surface thereof for receiving the top edge of an annodized aluminium cup reservoir. The top lid portion is dimensioned for the measurement of water which is poured into the lens well and hence into the aluminium cup reservoir through a plurality of apertures in the bottom of the lens well. These apertures also serve to allow steam from the water in the reservoir to enter the lens well which is in itself a steam compartment. A annular flat electric heater coil is glued to the bottom of the aluminium cup reservoir leaving a circular section exposed in the center thereof. A thermostat switch is attached to the surface of this circular section which opens after the water has boiled away cutting off the power to the heater. The top surface of the main housing and the cap member are each surrounded by an upwardly extending annular lip for moisture retention.
