An endoscope lens protection apparatus may include a clear indexable film strip positioned over the endoscope lens having an underside surface and an opposite exposed surface, such that the underside surface is positioned to face the endoscope lens, and the incision side surface is exposed; wherein the indexable film is movable from a clean film position to a used film position, such that, in operation, the indexable film is advanced from a point in front of the lens to a used film position out of the endoscope field of view, and may further include a sheath having a proximal end and a distal end defining a chamber therebetween configured to receive the endoscope body, an interior sheath surface defining a film supply channel and a film retraction channel. A sealing mechanism associated with the sheath may also be included.
