For sale is a pair of vintage Bausch and Lomb Arco 1/10 12 karat white gold filled aviator-look eyeglasses in very good preowned vintage condition. These are very cool because of their shape—are not the typical round or hexagon shape. They are marked on each temple stem and the underside of the bridge as “B & L1 10th 12k gf Arco” (stands for acid resistant coding).  These glasses contain prescription lenses, which include bifocals. Of course, if the buyer wants to wear them, the lenses will be have to be replaced. They measure approximately 4.5” from temple to temple, and the lenses are approximately 1.75” wide. They have the flexible wraparound ear stems. They do show signs of having been worn. Yellowing of the nose pads. Overall, however, they are quite good. They come with their original slim hard case.
