An apparatus for heat treatment (particularly asepticization) of contact lenses. The apparatus comprises a box having a housing adapted to receive a case for contact lenses and includes an electrical circuit comprising a power supply and at least one heating unit, with the heating unit having a heating resistor and a heat-sensitive switching device. The apparatus is characterized in that it comprises an electronic voltage threshold detection and programmed control.
