Wow! These sunglasses are awesome! I had never heard of them before my friend let me try a pair out. I can see things that I would never be able to see with other sunglasses. My friends think I'm crazy because I'm always pointing things out that they can't even see. I can see the ripple effect of the safety glass, on car windows and can see right through the reflection off of water, right to the bottom of lakes and streams. I've owned other polarized sunglasses before but they don't even come close to these. I would recommend these in any conditions, but especially for use on water.
