ABSTRACT:
An ultrasonic contact lens cleaning device has a housing with a hemispherical cover hingedly affixed to it. A container for a lens cleaning solution is mounted in the housing. An acoustic resonant structure in the housing is coupled to the container. The structure has piezoelectric components. A frequency modulated power circuit in the housing is electrically connected to and drives the acoustic resonant structure and provides a controlled level of ultrasonic cleaning energy.
