Fort Knox sunglasses

Not a knock against Ray Ban, but these babies are actually military-issued aviator sunglasses for about half the price. The depth-of-field, undistorted color-value relationships, UV and infrared filtration, glare and haze suppression, you know, all that stuff that can be a matter of life and death (if you're a combat pilot), all meet the exacting specifications of the U.S. Air Force. The Fort Knox sunglasses ($60) are also endorsed by De Niro (ok, not officially, but...dude).
