First off, these sunnies are awesome. They're stylish, durable, comfortable and they stay on your head when it's time to hit the trails or the rivers. The OHM lens helps with eye fatigue by offering crisp clarity and vivid colors which helps your eyes do their job without having to work as hard. Which in turn means longer days out doing what you love! I wear them all of the time and freakin love em. Fishing, rafting, hiking, biking, they've performed well in it all! I've yet to use them on the snow but I'm stoked see how they improve my days up on the slopes when I'm not wearing my EGG goggles!
