ABSTRACT:
A protective eyeglasses construction includes a frame portion comprising a lense frame piece and a pair of temple frame pieces, and a lense portion on the lense frame piece. The temple frame pieces are pivotally attached to the lense frame piece about vertical pivot axes, and they are adapted to be pivotally adjusted about horizontal pivot axes and longitudinally adjusted to different lengths. The lense frame piece includes an upper frame section and brow bar which is attached to the lense frame piece so that the central portion of the brow bar is spaced rearwardly from the central portion of the upper frame section and resiliently deflectable toward the upper frame section for cushioning the forehead of a wearer against physical shocks delivered to the lense frame piece.
