The optics from Oakley have always been among the best in sports sunglasses, but within the past year, a new feature has been making a huge difference: The hydrophobic coating on the RADAR RANGE wraparound shades repels water and sweat. It's not quite as powerful as an anti-gravity force field, but during an endurance run, it kept the glasses cleaner than any others we've tried. $180, oakley.com
