Recommendations for sunglasses that don't fog up during tennis? (normal, cheap, Florida)

I put this in Exercise and Fitness because the problem is finding sunglasses that don't fog up during sports (in my case, tennis.)

I have a pair that doesn't fog up during normal wear such as driving the car, but when I play tennis they fog up to the point that I can't see.

Rather than spending money trying different brands, I wanted to know if any has dealt with this and has a recommendation.

Under Armour makes a good line of sunglasses that do well with humidity. They aren't exactly cheap but they should last you a few years if taken care of.

Thanks, Florida!
