Abstract
Compositions and methods to clean contact lenses are disclosed. In one embodiment, the present composition comprises at least at least one enzyme capable of removing debris from a contact lens and at least one disinfectant destroying component capable of destroying a contact lens disinfectant which is incompatible with the at least one enzyme. The composition is structured so that the at least one enzyme is released in a liquid medium containing the contact lens disinfectant at substantially the same time or after the at least one disinfectant destroying component is released in the liquid medium, thereby allowing the at least one enzyme to remove debris from a contact lens in the liquid medium.
