ABSTRACT:
Welder's protective goggles particularly adapted for operators who must use corrective bifocal lenses in their work. The goggles comprise a generally tubular shaped member, having an open end contoured to fit snugly against the face about the eyes of the wearer. The axis of the open end of the tubular member is on approximately the same horizontal plane as the axes of the eyes of the wearer when looking straight ahead. The tubular member also has a closed viewing end which has at least one viewing aperture adapted to receive a safety lens. The axis of the closed viewing end intersects the axis of the open end at an angle from below it. The degree of the included angle formed by the intersecting axes is predetermined so that the tilt thus given to the closed viewing end in relation to the open end is such that the wearer of the goggles when using corrective bifocal lenses underneath them will have an unobstructed view when looking through either corrective section of the bifocal lenses. The tubular member is also provided with means for securing the goggles to the head of the wearer.
