It could be the 52mm one, and not the 55mm from the link, seeing how small it looks on his face...
American Optical. They held the government contract for aviator sunglasses for forever, but lost it a little bit ago to Randolph. They literally make the same glasses (I own one of both, they are identical) but AO ones come in less colors and are $50 BIFL sunglasses while Randolph ones are like $150, though they also have other styles of aviators too.
I'm going to pick up some American Optical Original Pilot Sunglasses. Should I get Silver, Gold, or Gold with green lenses?
American Optical is awesome for the aviator style, really nicely made, and a very good value at around $50 a pair. They are the original maker of aviators worn by US fighter pilots and NASA astronauts.
Edit: Amazon link, as they sell for cheaper via amazon than on the AO website.
