    Abstract: A contact lens washer having a plurality of disposable solution containers for sequential cleaning cycles using daily cleaning solution, enzymatic, solution, disinfecting solution and saline/neutralizing solution. The containers are inserted into the contact lens washer in an inverted condition. A plurality of liquid released solenoids cause the solution containers to inject liquid into a cleaning chamber having a pair of contact lenses to be cleaned. The contact lenses are encased in a lens-encasing member which is agitated to enhance the cleaning capabilities of the contact lens washer. A timing cycle module provides sequential fluid supply both to and from the cleaning chamber and controls agitation of the lens-encasing member.
