A method of cleaning and disinfecting a contact lens comprising immersing a contact lens in a treating solution, applying a direct current to the treating solution with repeatedly reversing a positive electrode and a negative electrode of a pair of electrodes plural times to generate peroxide and raise the temperature of the treating solution so that the interval of time before reversing is different from or equal to the interval of time after reversing to 50.degree. to 100.degree. C., and bringing the contact lens into direct contact with bubbles generated on the electrodes. Since this method is excellent in electrical safety and cleaning and disinfecting effects, contact lenses can be easily cleaned and disinfected.

Method for cleaning and disinfecting contact lens

An method for cleaning and disinfecting a soft contact lens, characterized by immersing the soft contact lens in a treating solution which does not generate any hypohalite during electrolysis, supplying a direct current, and raising the temperature of the treating solution; and a treating solution for a soft contact lens, characterized by containing a treating agent mainly composed of boric acid and borax in a concentration of at most 2.2 w/v % and having an electrical conductivity of at most 8 mS/cm are disclosed.

Method for cleaning and disinfecting soft contact lens and treating

A contact lens treating vessel equipped with an electromagnetic induction coil and a rectifier for converting an alternating current into a direct current, and an apparatus for treating contact lenses comprising a treating apparatus body for supplying electric power and the vessel which can be attached to or detached from the apparatus body, wherein the apparatus body is equipped with a magnet-generating coil and the vessel is equipped with an electromagnetic induction coil.
