Original abstractAn apparatus and method for counting the number of days that a wearer of contact lenses has used a particular pair of disposable contact lenses. In a preferred embodiment, a digital contact case is provided which comprises a body having two cups for contact lens storage and two reed switches, two caps for covering the cups, each cup having a magnet mounted thereon that closes one of the reed switches when one of the caps is snapped onto one of the cups. Each time both caps are snapped onto the cups, both reed switches are closed and a signal is sent to a microprocessor which increments by one the count of the number of days of contact lens use on a digital display. When the count reaches the number of days recommended by the contact lens manufacturer, the old pair of contact lenses is thrown away, a new pair is placed in the cups and the counter is reset by pressing a reset button.
