Years ago the old RCM magazine published an article by an opthomologist that pointed out that there was evidence that the RC community did have a higher incidence of cataracts and other eye problems due to staring into the big UV source, both direct and reflected, all day.  </p>

Point of the article was to always wear good UV protective sunglasses when you fly.</p>

I used to fly a bit of pattern and I found that any form of wraparound works best.  It was a bugger to be flying with the sun at your back to lose the plane when the sun glinted off the inside of the lens.</p>
