Abstract
Disclosed herein are industrial goggles. The goggles include a main body having protective glass and formed to correspond to a curvature of a face. A cover is hinged to one side of the front of the main body. A film unwinding roll has a film thereon. An unwinding-roll holding part vertically holds the film unwinding roll on one side of the main body and includes a stationary locking step, a movable locking step, and an elastic spring. A film winding shaft is provided vertically on the other side of the main body to wind the film from the film unwinding roll. A film feeding lever is coupled to the film winding shaft in a gear coupling manner and hinged to the main body. A ratchet means prevents the film feeding lever from rotating in a reverse direction. An elastic support member supports the main body against the face.
