A system for storing, cleaning, and sterilizing soft and rigid contact lens. The system utilizes the circulation of cleaning fluid to clean lens which are suspended. The system consists of a container for housing a pair of off-set lens carriers and for functioning as a chamber for cleaning and sterilizing; a cap with apertures for providing a generally water-tight seal for the container and for supporting the lens carriers, and a base/pump housing connected to the bottom of the container for retaining the cleaning fluid and providing a pump mechanism for propelling the cleaning fluid into the cleaning chamber. The container has a floor with a plurality of angled apertures for providing a helically shaped spray of cleaning fluid onto the lens carriers upon manipulation of the base and pump housing. The base/pump housing attached to the bottom of the container is a flexible housing for storing the cleaning fluid and for providing a pump mechanism upon compression for forcing the cleaning fluid through the angled apertures into the cleaning chamber. An interior vessel is provided for water-tight attachment with the cover within the cleaning chamber to retain the two lens carriers side by side during storage. The lens carriers consist of two generally parallel mesh concave surfaces for retaining the contact lens. The mesh surface has a plurality of openings for allowing impact of cleaning fluid onto the retained contact lens. An electrically driven pump actuator may be utilized to cyclically compress the base and pump housing for irrigating the retained lens for a specified period of time.
