Abstract
A contact lens storage case of limited life and predetermined usage to further the safe and effective use of contact lenses by ensuring patient compliance through both limiting case use over a set period of time and discouraging reuse and topping-off of the disinfecting and storage solution. Generally, the self-destruction consists of the case developing a leak in a pre-determined fashion as a result of the change in properties of a material in a limited area of the case following exposure of the case to the storage solution.
