Abstract:
A welding protector (1) has a curved eye protection shield (10) with an electrically switchable light filter. The welding protector further has a magnifying cover (20) for arrangement on an eye facing inner side of the eye protection shield. The magnifying cover is pre-shaped based on a curve that extends equidistant to the curve the eye protection shield is based on. Further, the magnifying cover has two optical lenses (27) which in combination only partially cover the eye protection shield.
