American Optical Vintage Glasses [American Optical --STADIUM] [Early 1960s-] Amber 46-20

American Optical model stadium Red dot screws that can be seen from the 50s to the 1960s are adopted, and from the AO logo, it seems to be the type of the early 1960s. It looks almost the same as the one in the late 60s to 70s, but the horn rim has less protrusion and the bottom of the frame feels a little thin and has a neat silhouette. Tart optical-like diamond hinges and distinctive keyhole bridge. Its a precious book in recent years, but I cant find anything especially old. We have newly added a light blue UV lens. There is damage in various places. Please check the photo. It has been appraised and maintained at an eyeglass store, and has been polished to give it a natural luster. * Both have small cracks near the corner of the temple.
