Just another humble sunglasses recommendation from yours truly. If you don't have the monies for Ray Ban or even Randolph Engineering your best bet for classic military frames is easily AO Sunglasses. For 130 years these shades have been made in the USA and have graced everyone from military pilots to the Eagle flight crew in the first moon landing. Getting that pedigree for 50 or 60 bucks (starting price) is a pretty damn fine deal, especially at about half the price of what competitors are offering. Just like Randolph Engineering, AO lets you customize things like lens size and the temple style so they should have your specific tastes covered. I'm partial to square frame aviators myself (i.e. Ray Ban's Caravan or AO's Original Pilot), but that's not to say tear drop frame aren't boss.
