I Have an old pair of eyeglasses that have a retractable chain about 18" long. They are rimless and no handles. The nose piece is very nice looks sorta of art deco, silver metal. On the brooch or fob, not sure what is called. Has all the information, there are two patent dates Feb. 24'03 and Apr. 26'10. They are in very good condition. No scratches that I can see, look like regular glass with bifocals on the bottom. The lens are six sided. Any information, and value. Thank You! Can not load pictures say's can not find upload???
