When using an information display device such as a pager in a harsh environment, the information that is displayed can become unreadable from an accumulation of debris from the surrounding environment on the display surface (i.e., paint, dust, soot, etc.). Permanent damage to the display surface (lens) can occur when an attempt is made to remove the foreign material from the display surface (i.e., scratches, discoloration, etc.). In such cases, the lens would have to be replaced. Optional carrying cases have been designed for such display devices that allow the user to view the display while protecting the display surface from the environment. This, however, merely diverts the damage from the display device to the carrying case causing replacement of the case to become necessary.
