Eyewear That Makes You Look Younger

To make blue eyes pop, shop for bold, blue frames, says Ashley Turen, founder of A. Turen Boutique in New York City. "They will mimic the effect of makeup to emphasize the eyes, so there is no need for shadow." Go retro and snag an affordable pair of Ray-Ban RB5268 Eyeglasses ($70, ray-ban.com).

Try a slightly larger frame that has more of a structured square shape, a style that Turen recommends for long faces. "The bigger proportion will help add width and balance your face," she says. For a more conservative, classic look, consider the Elizabeth and James Augusta Glasses ($215, shopbop.com).

Look for frames with rounded edges to soften a square-shaped face. "Think Demi Moore in her super sexy, 'nerd' glasses," says Turen. Black frames, like the Retro Super Future People Glasses ($154, farfetch.com), also help dark hair and eyes pop.

If you're hunting for a frame that goes unnoticed instead of standing out, opt for something thin and understated. Choose soft, round wires like the Ray-Ban RB6242 Eyeglasses ($168, ray-ban.com). This subtle pair will stay out of the spotlight, focusing the attention on your gorgeous hazel eyes.

For defined cheekbones, shop for glasses that are smaller in length and have upturned corners, says Turen. "The cat eye shape gives the illusion of an instant facelift and will highlight your bone structure." An edgy pair of Tom Ford Eyewear Modern Cat's-Eye Plastic Eyeglasses ($385, saksfifthavenue.com) is perfect for a fashion-forward woman.

Aviator frames are a timeless classic found in every fashionista's bag of tricks. Turn up the volume with a pair in gold, with cognac lenses. Universally flattering on most face shapes, aviators, like the Foster Grant Scout Polarized ($25, walgreens.com), will never go out of style.

Cateyes have been big for the past few seasons, and topping off your ensemble with a pair is an easy way to look young and chic. "Add a little gold embellishment and — voila — instant, old-school Hollywood," says celebrity stylist Eric Himel. Cateye frames, like the Nanette Lapore CFDA (exclusive for Sunglass Hut, $130, sunglasshut.com), soften your face, while the turned-up corners help you look more feminine.

If 2012 was the year of the Ray-Ban Wayfarer, 2013 is going to be all about its cousin, the Clubmaster ($145, ray-ban.com). These bold sunglasses universally flatter all face shapes while giving you a young, hip appearance, says Himel. "Stick with the black or tortoise colors for a classic look. Both work equally well with a t-shirt or a little black dress."

Protect your eyes from the harsh UV rays with Retro Super Future People Glasses in Light Havana ($154, farfetch.com). "The color on these glasses works beautifully with honey-colored and blonde hair," says Turen.

An oversized frame like the Mossimo Gradiant Sunglasses ($17, target.com) poses a challenge for most face shapes, but some can flawlessly pull it off, says Himel. And if you can, you'll reap compliments for seasons to come.

If you have a narrow face and love the look of rounded frames, consider a funky pair of Jeanne Sunglasses by Kate Spade ($128, katespade.com). "This is what I call 'glass frame confusion,' " says Himel. "They are both rounded and squared at the same time."

"Round frames are very au courant this season, but they are not for every face," says Himel. "Pass on this shape if you have a round face." If you don't, try the stylish Tory Burch Oversized Print Sunglasses in Python ($149, toryburch.com) for a youthful glow.

Combining materials such as tortoise and brushed gold makes for a total luxe feel. If you've got a little more room in your budget, flaunt Tod's super mod Tortoise Shell with Metallic Detail Sunglasses ($350, tods.com).
