Fort Knox Sunglasses Polarized
DetailsFort Knox Sunglasses. 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). They don’t cost $250 or $5 (sorry). They cost $189. And for that, you get the best. Made in USA.
