ABSTRACT:
A contact lens bathing case, in which a pair of contact lenses is sealed with a cleaning and disinfectant solution, and a heating unit, for receiving and heating the filled case therein, cooperate to eliminate leakage problems, i.e. loss of solution, associated with improperly closed contact lens cases. The heating case includes a heating element and a movable lens case holder which is movable from an open position remote from the heating element to a closed position adjacent to the heating element whereat the solution and lenses may be heated. Closure prevention means prevent the holder which has received an improperly closed case from being moved to the closed position.
