Abstract
A contact lens storage device and method is provided. The contact lens storage device includes a housing, a cover for the housing and a counter. The cover is cooperatively arranged with and attached to the housing such that the counter automatically operates to display number of days that the contact lenses have been worn by the contact lens wearer. Thus, the contact lens wearer is likely to refrain from using contact lenses beyond the useful life of the lenses.
