A contact lens disinfector unit (10) includes a housing, heating means arranged to heat the contact lenses and the associated lens case (21) to a disinfecting temperature and for thereafter terminating the application of heat to allow the contact lenses to cool, and temperature indicating means (30) for indicating if the lens case is cool enough for safe handling. The temperature indicating means includes a viewing window (17) having opaque portions (38) and transparent portions (37). The transparent portions are arranged to define a temperature indicia. The temperature indicator also includes a plate (35) which has indicia thereon corresponding to the temperature indicia and a surrounding opaque background. The plate is slidable with respect to the viewing window between two positions, one of which indicates that the lens case is too hot to handle, and the other of which indicates that the lens case is cool enough to handle.
