Abstract

An object such as a contact lens is immersed in a solution comprising disinfectants, deposit removers, detoxifying compounds and neutralizers which react with each other to clean, disinfect and remove harmful deposits from the lens in an all in one action. The lens is then rinsed briefly before being re-inserted in the eye.
