Abstract

A system by which contaminants from and below the surface of contact lenses may be electrokinetically removed. The system includes a protective encasement packet in which a lens is safely protected upon its removal from the eye, through the cleaning procedure, and until the lens is returned to the eye. The system includes also a cleaning assembly in which the lens as encased within the packet is decontaminated. The cleaning assembly includes surfaces positionable to contact the packet and from which electrical charges are transmitted to the lens. Under the influence of the electrical charges, contaminants are drawn off of and from below the surface of the lens.
