ABSTRACT:
A contact lens holder is provided with a pair of receptacles to receive a pair of contact lenses for holding them in place while they are inserted into a container. The container has liquid therein to be heated to a sterilization temperature, thereby sterilizing the contact lenses. A relatively movable vessel is positioned within the container and held in a desired position during the heating operation. The vessel is formed of transparent material and contains a quantity of eutectic material viz. a material having a specified melting point. At the outset of the sterilization process the vessel is positioned such that the eutectic material, solid at temperatures below the sterilizing temperature, is at top of the vessel. The eutectic material melts once the sterilization temperature is reached and will flow to the bottom of the vessel, thereby indicating that the sterilization temperature has in fact been reached upon subsequent cooling and removal of the holder. Since the eutectic material solidifies upon cooling, subsequent reuse of the contact lens holder requires only that the vessel be inverted to again place the solid eutectic material at the top of the vessel.
