Abstract
A system for disinfecting a contact lens includes a first container section holding a first liquid medium containing hydrogen peroxide. A second container section is provided and holds a second liquid medium containing a hydrogen peroxide destroying component. The first and second container sections are configured to substantially simultaneously provide the first liquid medium and the second liquid medium to form a combined liquid medium containing an amount of hydrogen peroxide from the first liquid medium effective to disinfect a contact lens contacted with the combined liquid medium and an amount of hydrogen peroxide destroying component from the second liquid medium effective to destroy at least a major amount of the hydrogen peroxide in the combined liquid medium.
