none of that crap works. quit surfing if it bothers you that much. my dr told me to quit 20 years ago. can still see fine.
Turn your back to the sun and look over your shoulder with the corner of your eye, don't stare straight into it, if that doesn't work use your board like Gaffer said, but make sure it's really crowded when you do this.
For a second there, I thought I came up with a revolutionary idea, but looks like some d*ck came up with it first, here's your best bet...........http://www.popsci.com/technology/ar...-transition-contact-lenses-replace-sunglasses
Me and my buddies like our seaspecs. We don't have a problem with fogging up. You see better without glasses, but then your eyes get radiated. A local surfing legend died of eye melanoma this year, from years of surfing. You gotta decide what's most important to you.
I've worn the Dakine hat during mid-day surfs in CR and, you're right Gaffer, it's annoying in decent-sized surf. On the other hand, gringo skin like mine is no bueno in the cooker sun the first couple days, so the lid helps. Just another trade-off. Like Betty said: what's important to you. Sea Specs: tried 'em for east coast DP. Sometimes they fog & sometimes they don't. (Depends what I'm thinking about.) But after the sun is up, they're a hindrance. Just for the helluva it, I coated the outside of the Sea Specs lenses with RainX; it actually helped the beading.
I prefer a welding helmet with a #10 lens, its a multipurpose thing, saves your eyes and its really good head protection....
