Abstract
A method is disclosed for disinfecting contact lenses with peroxide whereby the usual peroxide neutralization step is eliminated. This is accomplished by carrying out the disinfecting process at a hydrogen peroxide concentration of about 0.01 to less than 0.5% (w/v). In the preferred embodiment the peroxide is introduced into the system utilizing an effervescent tablet of an alkali metal perborate, percarbonate or persulfate, or urea peroxide.
