CA 1297403

The specification discloses a method of caring for a contact lens and a neutralizing agent for use in a contact lens care set. The set is disclosed as having a container for receiving the neutralizing agent, the lens, and a liquid comprising hydrogen peroxide. The neutralizing agent comprises decomposing means for decomposing at least residual hydrogen peroxide on the lens into oxygen and water after the hydrogen peroxide has so sterilized the lens; and retarding agent means for delaying the time at least the decomposing means decomposes the residual hydrogen peroxide after the neutralizing agent is received in the container until after the hydrogen peroxide has so sterilized the lens. The invention provides a contact lens care set which, in one step, keeps hydrogen peroxide active sufficiently long at least for substantially sterilizing the lens and then neutralizes at least residual hydrogen peroxide on the lens at least substantially so that the lens can then be worn, at least generally, without discomfort.
