Abstract
A housing supports a tray for slidable movement of the tray within the housing. The tray and the housing may be paramagnetic. The tray is shaped to define at least one cup for receiving a contact lens and cleaning fluid. The tray may be supported on a resiliently compressible pad which is in turn supported on a ledge forming a part of the housing. A slug is supported by, or embedded in, the tray to provide for a movement of the slug with the tray. The slug may be magnetizable and may be displaced from an armature and a coil enveloping the armature. When the coil is energized, it magnetizes the armature. The energizing of the armature causes the slug to be attracted to the armature in a direction to compress the pad. When the coil is de-energized, the compressed pad expands to move the tray away from the armature. In this way, the tray is vibrated in directions to displace the contact lens from the wall of the cup and to agitate the cleaning fluid so that all of the surfaces of the contact lens are cleaned. The vibrations may occur at frequencies below the frequencies of sound or in the ultrasonic range.
