And despite what this jargon suggests, sunglasses aren't all that complicated. The important thing to remember about polarization is that it's not for everyone. True, it's essential for a windsurfer screaming toward rocks submerged beneath a sun-dappled lake. But road bikers and mountaineers should avoid polarized lenses because they can't afford to miss the glare from road slicks or patches of boilerplate ice. Lens material isn't any more complicated.
Polycarbonate lenses are lighter and more bonk-resistant than glass, but lack glass's clarity.
Wear polycarbonate for a sport that smacks you around, like mountain biking. Wear glass for fishing, alpine climbing, or sailing, where you need sharp vision. And finally, of course, try to choose a pair of shades that helps you look cool. Fortunately, all the models we've selected will give you an extra edge in that department. Mariah Media Inc.
