Abstract: A device for cleaning contact lenses comprises three liquid containers removably mounted one above another on a support. Each container has a liquid inlet and the two upper containers each have a liquid outlet, controlled by a valve in communication with the inlet of the container below it. In use, contact lenses are initially immersed in sterilizing solution in the middle container, and the upper container contains neutralizing solution. After a preset interval, a timed valve control device on the support operates the valves in sequence to discharge the sterilizing solution from the middle container into the lower container, and replace it with sterilizing solution from the upper container.
