ABSTRACT:
A generally conventional welders' shield is provided including a support frame for placement over and support from the upper portion of a welder's head and a rearwardly opening upstanding shield body pivotally supported from opposite side portions of the frame. The shield body includes a viewing aperture therein to be in horizontal registry with the eyes of the wearer of the frame when the shield body is in an upstanding position and the upper margin of the viewing aperture is at an elevation to be at least horizontally aligned with straight forward vision of the eyes of the wearer of the frame. The lower margin of the viewing aperture includes opposite side portions depressed downwardly sufficiently to provide unobstructed vision of the wearer when the latter is viewing through the lower portions of bifocal glasses and the center portion of the lower margin of the viewing aperture is upwardly displaced relative to the depressed opposite side portions of the lower margin to be positioned above the nostril level of the wearer. Further, a light filtering panel is removably secured over the viewing aperture.
