For your consideration is this vintage pair of Bausch and Lomb Clip-on Aviators in size 48mm in their original tan case.
The frame is all original with no signs of repairs or alterations.
Both lenses are intact and not chipped, but they do have adhesive in various spots between the frames and the lenses, not in the field of view; I tried to show this in the pictures. A good ultra-sonic cleaning should remove all the adhesive residue
