Abstract

The invention relates to devices for use in sterilizing contact lenses. <??>The device incorporates a casing enclosing a flat heater block (42 min ) comprising a primary segment (42a) and an extension segment (42b) of less size and mass than the primary segment extending from one side of the primary segment, the primary segment being formed with a support surface (62) and with a recess (64) accommodating an electrical heating element (66) and the extension segment supporting in contact therewith a thermostat (70) in controlling connection with the heating element. <??>The device provides that the support surface will reach the desired sterilizing temperature and remains at that temperature long enough to sterilize lenses in a case (46) resting on the surface before the thermostat operates because owing to the differential masses of the primary segment and the extension segment the rate of heat transfer to the thermostat is less than the rate of heat transfer to the support surface.
