ABSTRACT Contact lenses can be cleaned effectively in a short time, by using a kit for contact lens cleaning which comprises an oxidizing agent for removing stains adhering to contact lenses and a reducing agent for making nontoxic the oxidizing agent still remaining after stain removal and wherein the oxidizing agent and the reducing agent are each in such a form that when they are placed in water substantially simultaneosuly, the major portion of the oxidizing agent dissolves in the water more rapidly than the major portion of the reducing agent. Further, with this kit, the cleaned contact lenses can be made nontoxic without fail.
