Abstract

A process and apparatus for the care of contact lenses in which the process comprises supporting contact lenses on a lens holder within a treatment container provided with a motor-driven stirrer and introducing into the container a liquid, e.g., salt water, and a two-component system including (1) a first component providing a peroxide-compound cleaning and sterilizing solution, preferably in solid form and (2) a second solid component containing a catalyst or reducing agent providing a neutralizing solution wherein the second component dissolution is delayed until after the first component has acted on the contact lenses, and wherein the action of both components is effected under stirring; and the apparatus for practicing this process comprises a housing, a treatment compartment in the housing to hold a liquid, a lens holder removably supported in the compartment, a stirrer movably positioned in the housing which is separate from the lens holder and which extends into the compartment and drive means to move the stirrer and agitate the liquid in the compartment.
