ABSTRACT:
The eyewear for industrial use comprises a deformable arcuate lens with a pair of temple receiving entries at opposite ends thereof, a deformable brow frame shaped to fit the upper edge of the lens so as to be engageable therewith and a pair of temple pieces, each piece being hingedly connected to a respective opposite end of the brow frame. Assembly of the temple pieces and brow frame to the lens is easily effected by inserting the temple pieces in the entries of the lens and by snap engagement of a mid-section of the brow frame to the upper edge of the lens. The assembly is made of plastic material so that it may be resiliently deformed to adapt to the various sizes of head of users.
