In my line of work, I'm a photojournalist, I need quality sunglasses. After all you can't expect to fire-off a quick few frames at an instants notice & capture the 'money-shot' when your eyes are worn-out after a day squinting in the sun. The photochromic lenses ensure that your eyes are adjusted & relaxed in any light level - blinding sun or gloomy shade. The anti-reflective coating on the rear of the lenses keeps your eyes protected even when your back is to the sun. The polarizing ensures that you are seeing the rear scene, not the glare & flicker. And yet get all of this from a pair of shades that look very, very cool.
Pros: Lens optical quality & clarity
Cons: Slightly heavy after all-day wear
