Shady business

Plutonite, Grilamid, O-Matter, Unobtanium. Sounds like we're back in high school chem class, but they're actually the high-tech components that make up the latest crop of sophisticated sports sunglasses. We're giving you five of the hottest options out right now. They've got the fancy features that have the pros clamoring to get made in the shade. Read on to see the light.

IF YOU RUN OR CYCLE

Opt For: The Bolle Helix, $190, bollé.com These specs are engineered with runners and cyclists in mind but, really, they are for anyone who pushes herself -- freakishly hard (professional volleyball player Tamsin Hinchley is a fan). Narrow and aerodynamically-shaped, the women's-specific Helix has vented temples to keep you dry and fog-free; this also shaves weight from the frame. Choose from three lens options based on your sport: One is all about clarity, another gives bonus protection from dirt and pebbles, and another repels sweat and infuriating smudges.

IF YOU GOLF

Opt For: The Tifosi Wisp, $69.95, Tifosioptics.com The lenses on these shades are fitted with a special lens that filters out blue light, giving you an enhanced "green reading." Translation: You can see every dang contour so you can better plan every putt and drive. Additionally, the lenses automatically adjust to changing light conditions, getting darker when the sun is apt to blind you, and lightening up when the clouds roll in. Fore!

IF YOU PLAY TENNIS

Opt For: The Maui Jim Lighthouse, $149, mauijim.com Fast moving sports like tennis call for lightweight frames and tinted lenses that offer both clarity and protection. For that reason, tennis pro Sabine Lisicki is a fan of the Lighthouse, which is super minimalist (you hardly know they're on). The rimless lenses cut 90 percent of glare so you don't have to squint or deal with tired eyeballs. Also key, a smudge-proof coating on the specs protects them from not only water and sweat, but also greasy sunscreen fingers. Four lens color options are available, but we're big fans of the Maui Rose for total control in all conditions.

IF YOU PLAY VOLLEYBALL

Opt For: The Oakley Commit SQ, $150, Oakley.com These shades have a beach volleyball rep because Olympian Kerri Walsh wears them, but they're equally ideal for trail, track, court, or greens. The curvature of the lens provides impressive peripheral vision while protecting your peepers from, say, flying sand. And the plutonite lenses banish UVA/UVB/UVC rays and harmful blue light, which is exactly why Walsh wears these babies on tour. If you sweat like crazy, here's some additional good news: A hydrophobic treatment prevents the dreaded lens smudge, and ear and nose pads become even more secure when you start dripping.

IF YOU'RE A TRIATHLETE

Opt for: The Rudy Project Noyz Pink FLUO (with multilaser blue lenses), $180, Rudyprojectusa.com These wraparound sunglasses are a favorite of Tour de France cyclists, triathlete Yvonne van Vlerken, and ultra marathoner Shanna Armstrong. A cleverly engineered adjustable nosepiece and temple grips provide a perfect fit for any size head, be it pea-sized or a virtual melon. And the military-grade lenses (read: bulletproof) are not only incredibly lightweight but also incredibly clear in all weather conditions. One feature every hard-playing athlete is sure to appreciate: Hidden hinges. Without exposed metal, your pretty mug is protected during spills.
