Abstract
A contact lens cleaning system, process and kit includes an aqueous chlorite solution and a solid component including an agent for accelerating decomposition of chlorite and an oxygen consumption agent. The chlorite decomposes to form free oxygen which removes impurities from a lens to be cleaned. The oxygen consuming agent prevents excess free oxygen from attacking the lens after the impurities have been removed.
