Abstract
Abstract Safety spectacles comprising a front and pivotally attached temples adapted to extend rearwardly from the front. Each temple has a portion recessed inwardly relative to an adjacent portion of the front to form a passage to the region behind the front for ventilation. The recessed temple portions extend forwardly of the rear edges of the front so as to overlap the adjacent portions of the front and thereby increase the degree of protection to the wearer.
