Abstract

A contact lens cleaning system having a chamber and a pump for generating streams of cleaning fluid within the chamber. The lenses are carried in lens retainers which rotate within the chamber and are exposed to the streams of cleaning fluid. The lens retainers are mounted on a single spindle held at both ends. The rotatable disposition of the lens retainers allow the lens to rotate and thus a greater extent if not essentially all of the surface area of the lens experiences the enhanced cleaning effect of the streams of cleaning fluid. The holding of the spindle at both ends insures that a uniform distribution of the impingement of cleaning fluid across the lens may be effected.
