Patent ID: 8556435

Claim:
An apparatus for drying a recessed lens of a tubular outdoor viewing device comprising: a tubular body configured for positioning and retention over an end of the viewing device proximate to the lens; and a cap in communication with the body, the cap dimensioned to be movable with respect to the body, and the cap configured for moving between positions including a position where the cap covers the lens, and a position where the cap is maintained at least substantially clear of the lens, such that the apparatus remains on the viewing device while the viewing device is in use, the cap including: an inner portion adapted for contacting the lens when the cap is in the position where the cap covers the lens, a layer of moisture-wicking material covering at least a part of the inner portion, and an outer portion adapted so that, when the cap is in the position where the cap covers the lens, a user causes the layer of moisture-wicking material to contact and move about the lens by manipulating the outer portion, thereby drying the lens.
