  • Patent number: 5759540
    Abstract: A method and case for disinfection of contact lenses wherein the contact lenses are placed in a double chamber filled with cleaning fluid, for example, hydrogen peroxide, with the case comprising a third chamber or position connected with the double chamber. The third chamber is adapted to take up and hold a tablet containing a neutralization agent such as catalase, so that the hydrogen peroxide in the double chamber is neutralized suitably slowly by admission of the cleaning fluid to dissolve the tablet. By the dissolution of the tablet, oxygen is generated, and an oxygen bubble is formed around the tablet so that the hydrogen peroxide is alternately kept from the tablet and ultimately is admitted access to the tablet. Rather than provide a double chamber, a holder member may be provided for holding the respective contact lenses, with the tablet being accommodated at a lower end of the holder and being exposed to the cleaning fluid when the holder is inserted into the cleaning fluid.
