Abstract
Compositions and methods useful in destroying residual oxidative disinfectant, e.g., used to disinfect a contact lens, are disclosed. In one embodiment, the method comprises contacting an oxidative disinfectant-containing liquid medium with a material selected from glutathione, oxidized glutathione and mixtures thereof, and a co-factor selected from nicotinamide adenine dinucleotide phosphate, nicotinamide adenine dinucleotide and mixtures thereof in the presence of glutathione reductase in an amount effective to promote the oxidation of the co-factor.
