ABSTRACT:
A safety spectacle providing front and lateral impact protection. The spectacle includes a frame, a removable lens incorporating integrated upper and lower side shields connected to the frame by means of a nose bridge, and a pair of length and pantoscopic adjustable temples arm assemblies hingedly connected to the sides of the frames. The temple arm assemblies are adjustable lengthwise by earpieces which can be locked and unlocked into slots on an intermediate arm receptacle by means of a quarter turn barrel configuration. The temples are adjustable pantoscopically by means of a pair of semicircular arms, both of which are hinged at the front to the side of the frame between a pair of outward sloping walls and inserted at the rear into a threaded ferrule. One arm is threaded inside the ferrule and allowed to move in and out when the ferrule is rotated while the mating semicircular arm is stationary, thereby varying the angle of the temple within the sloped walls and thus the frame.
