ABSTRACT:
Contact lens cleansing apparatus comprises at least one cavity for containing a contact lens together with cleansing a liquid. An ultrasonic transducer applies ultrasonic frequency mechanical vibrations to the liquid and lens contained in the cavity. Oscillating means for driving ultrasonic transducer at a substantially stable resonant frequency includes a dual ferrite core transformer feedback circuit which minimizes energy consumption. There is also a timer whose operation is controlled from the oscillating means. Simultaneous cleaning and sterilizing of a contact lens is achieved.
