Vintage glasses [USS] [1960s-] Safety GI glasses

Vintage [US Safety Service Co.] glasses from the early 1960s. This clear cell is an item that has disappeared in recent years because it was supplied by the US military and became black in 1968. At that time, it was so dull that it was commonly called Rut Prevention Glasses, but now it is so popular that it is reprinted because of its simplicity, Wellington type, easy to wear and classical. It is very similar to the safety of American Optical at that time, and the causal relationship is unknown, but the solid appearance and the daily use appearance are hard to tell at first glance. This is a rare specification with a nose pad, and it is a nice specification that does not slip on the nose when worn. It features a precious large size and a clear frame of grayish light olive that is familiar to the face and has a feeling of intimidation. We are introducing a new light blue UV lens that has been maintained at the eyeglass store. The size of the temple (or rope) can be adjusted. (At your local optician) We have scrutinized the condition, but since it is a vintage item, there are threads and scratches. Please purchase after understanding the characteristics of vintage and antique.
