ABSTRACT:
A welding helmet is fitted with two lenses, one tinted and one relatively clear. The tinted lens is mounted forward of the eyes of the viewer and the clear lens extends obliquely away from the tinted lens towards the face of the wearer. To view the workpiece through the clear lens a wearer need only tilt the helmet without the necessity of raising his hands.
