Abstract

A film roll for use in a film advance system for eye protective goggles comprises a transparent film wound on the spindle. The film has an inner trailing end, a leading end, and a total film length. In use, the transparent film extends across a lens of the goggles. The transparent film presents a transparent main film part, which extends in the longitudinal direction from the trailing end to the leading end, and which presents optically uniform characteristics at least in the longitudinal direction. The transparent film is provided with at least one visual indication, which is located above the main film part and extends along an upper film edge of the transparent film, said at least one visual indication being limited to a trailing part of said total film length.
