Just got a pair of 7eye sunglasses with their ColorAmp Copper lenses. Amazing - it's a cloudy day here in the PNW, put these on and it's like living life in high definition. They also have an 'air dam', basically a foam liner on the inside of the frame around the lenses to reduce glare, reduce wind and help with anti-fogging. These seem like they would be great on the slopes, especially in the spring when I usually swap my goggles for sun glasses.
If you go to their website, www.7eye.com they have a code to get 50% off.
