Last year I bought a pair of Zeal Optics based on the recommendation from the Outside Buyers Guide. Overall I love them, but I've been having a big problem, especially since it's getting hotter and hotter down here in Houston. They seem to fog up fairly easily, and collect sweat along the top of the frame. I've tried wearing them lower on my nose, but they aren't as comfortable.
Can anyone recommend any sunglasses or lenses that don't fog up easily? I've seen the Oakley Radars advertised with some sort of treated lens, but I haven't gotten a chance to look at them yet, and they're fairly expensive. I'm not stuck on any one brand, so any suggestions are welcome.
