ABSTRACT:
There is disclosed a contact lens disinfector unit for disinfecting contact lenses contained within a lens case. The disinfector unit includes a housing having a forward end wall and a rear end wall and a heating block within the housing. A resistive type heater is engaged with the block and is coupled to an electronic circuit and connector to adapt the unit for connection to a voltage source for causing the heating of a contact lens case in engagement with said block, and the contact lenses contained therein to a sterilizing temperature. The housing forward wall includes an aperture which slidingly receives a drawer having a pair of upstanding spaced apart panels and a contact lens case receiving aperture therebetween. The rear panel is disposed between the housing end walls and is greater in dimension than the forward wall aperture dimension to provide an abutment stop against the foward wall when the drawer is fully displaced from the housing, and also for preventing contact with the heating block and the voltage source connected thereto. The forward panel is also of greater dimension than the forward wall aperture for entirely enclosing the housing when the drawer is fully within the housing. The lens case receiving aperture of the drawer is arranged to be positioned above the heating block when the drawer is fully within the housing to provide surface contact between the undersurface of the lens case and the upper surface of the heating block during the sterilization cycle.
