Abstract
An electrophoretic technique and apparatus for decontamination and sterilizing of contact lenses are provided. The lenses are placed in respective perforated containers and inserted in a buffer solution of suitable pH value. An electric field is established in the solution by a pair of spaced electrodes. Contaminants on the lenses become charged and are attracted to a respective electrode, thereby cleaning and sterilizing the lenses.
