ABSTRACT:
A date indicator for use with a contact lens case having a base and at least one lens container is disclosed. The indicator comprises a lid to selectively close the at least one contact lens container. A generally annular day wheel has a plurality of day indicators on an upper surface thereof, and is rotatably captured within a cylindrical depression of the lid. A generally circular month wheel includes a plurality of mouth indicators on an upper surface thereof, and is rotatably captured on a central spindle of the lid. A torsion spring is fixed to a spring mounting mechanism of the day wheel. One end of the spring engages a sawtooth-notched wall of the month wheel and the other end of the spring engages a sawtooth-notched wall of the lid. The spring allows the day and month wheels to rotate in one direction together while preventing the day wheel from rotating in the opposite direction. The day wheel may be set at a desired day indicator by rotating the month wheel and day wheel together in the one direction. The month wheel may be set at a desired month indicator by rotating the month wheel in the opposite direction.
