#$%^&*AU2019283838A120200116.pdf#####ABSTRACT A curved eye protection shield for welding protection. The eye protection shield has an electrically switchable darkening filter and a protective cover. The darkening filter has a refractive power and eye facing major inner and outer surfaces, and the protective cover has major inner and outer surfaces. The protective cover is provided for arrangement on the inner surface of the darkening filter. The inner and outer surface of the protective cover are shaped to compensate for the refractive power of the darkening filter.
