Abstract
A countdown timer contact lens case is provided for removably receiving a receptacle and providing independent timing functions for displaying the useful remaining life of a contact lens and for the receptacle for receiving the contact lens when not worn. The countdown timer contact lens case includes a receptacle carried by a main body. The main body includes a timing circuit and a display with first and second indicators corresponding to the respective remaining time for desired use of the lens and for the receptacle. The timer for the lens displays a maximum value which is less than the displayed maximum value of the timer for the receptacle. The timer corresponding to each of the lens and the receptacle can be independent set and reset, and a warning feature is provided to signal the user when the corresponding displayed lens or receptacle value diminishes below a minimum, or decreases to zero.
