The lenses are great. I rode mine a whole season and yardsaled them in the pow and smacked them on branches when ripping through the trees, and the anti-fog is the best I have seen in any of my previous goggles. Even after wiping loads of snow out of them. The 2 layer spherical lens is amazing, your field of vision is better than any other goggle out there. The bronze-silver chrome lense is completely mirrored, so it is amazing on sunny days, and looks super good. If you ride somewhere that has a TON of foggy days think about a different lense. My mountain has fog most of the year, but only on days where I had 10 yd visibility were the only days I had any real trouble seeing anything. Other than that, you can't beat the view of this goggle. Virtually no blind spots.

lens replacements can be found at prolens, the 'chrome' finish scratches easily so be careful
