Description
Fort Knox Sunglasses (No. J2932). Disturbing instances of expensive, supposedly reputable sunglasses failing to adequately filter harmful UV radiation are not rare, nor the converse, $5 sunglasses that test far better than the $250 kind. The problem is how do you know which is which? You don’t. That’s what we like about these: they were developed by American Optical to meet the exacting specifications of the U.S. Air Force (MIL-S-25948J). For that, you get the best. Made in U.S.A.
