Fort Knox Sunglasses.

For combat pilots there are moments when distance and depth-of-field judgments, undistorted color-value relationships, UV (a & b) and infrared filtration, glare and haze suppression, and other factors, can be a matter of life and death.

Strolling along Rodeo Drive in your $250 “designer” sunglasses, these factors are not, perhaps, a matter of life and death.

Good thing they're not. 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 $175.They cost $98. Buy them at the Fort Knox PX or from us. Either way, you can stop worrying. You've got the best.
