ABSTRACT:
An apparatus (100) for cleaning contact lenses is disclosed. The apparatus comprises a housing (110) having first (112) and second (114) housing sections which are joinable to form a chamber for receiving the lens. Each of the housing sections has an operative face (118, 120, 124, 126) facing the chamber formed for receiving the lens. A reactive layer (122) is provided on a portion of each operative face and the operative faces and the reactive layers are dimensioned and arranged whereby the reactive layers come into engagement with respective surfaces of a lens (155) positioned therebetween when the first and second housing sections are joined together. A portion of at least one of the operative faces is recessed relative to the other operative face to define an open volume within the chamber when the first and second housing sections are joined together. The first and second housing sections can be constructed to be in fluid communication when the apparatus is in an opened position.
