WOW! These look very vintage and I am sure that if they are American Optical
they would be more than happy to help you identify them! I tried to see if there is something online that will help with deteriming what these are, but I had no luck with these sunglasses
. I think you should get into contact with someone there and see if they are able to assist you, by having you send them over some pictures. You can reach them at 1-800-777-1173. Good luck!!
