Abstract
A method and composition for disinfecting a contact lens is disclosed. The method includes treating a lens with an aqueous solution having reduced toxicity to the eye which contains an effective amount of a monoperphthalic acid compound in a concentration of less than about 0.5% by weight of the solution. The lens disinfecting solution is capable of disinfecting contact lenses without irritating the eye due to reduced toxicity of the composition.
