Claim Text:
1. A contact lens disinfecting system comprising: (i) a metal catalyst component; and (ii) a contact lens disinfecting solution having a pH of from 6 to 8 and including 1 to 10% hydrogen peroxide and at least one of an organic carboxylic acid and a salt thereof, wherein the organic carboxylic acid is at least one selected from the group consisting of glycolic acid, tartaric acid and citric acid; wherein the hydrogen peroxide is neutralized when the contact lens disinfecting solution contacts the metal catalyst component, and the at least one of the organic carboxylic acid and the salt thereof increases a rate of neutralization of the hydrogen peroxide, the contact lens disinfecting solution being configured to have an osmotic pressure of 250 to 350 mOsm after the neutralization, and wherein the hydrogen peroxide in the contact lens disinfecting solution is stabilized such that an amount of hydrogen peroxide that would remain after heating the contact lens disinfecting solution at 40° C. for 3 months is 90% or more of the amount of hydrogen peroxide in the contact lens disinfecting solution before heating.
