I've used Barz goggles with prescription lenses for 4 years - they are excellent at keeping the spray out of your eyes. Sunglasses just don't cut it on a screaming reach in big waves. I have 2 pairs - one with grey polarized lenses that I use most of the time. The polarized lens lets you see puffs more clearly and also helps with spotting weed/wildlife early enough to avoid it hitting the boards. My second pair have light yellow lenses for low light or night sailing.

I don't know if you can get the photocromatic lens with polarized. If so then this could be a sweet option. I sometimes put rainex on the outside of the barz to keep them really clear - but they do OK without. Fogging has only been an issue for me in light air. My solution - pull them down over your mouth and give the inside a good lick. Gross, but effective (Divers sometimes spit into their masks for the same reason).
