Knowing how to make your eyes look bigger also requires choosing the right eyeliner. Kaye says to waterline your eyes with a cream or white pencil -- think: Lady Gaga in the "Bad Romance" music video, only less extreme -- this will act as an optical illusion, making the whites of your eyes appear bigger. (Bonus: It also helps your eyes look whiter and more awake.)

Our latest obsession: Charlotte Tilbury Rock n' Kohl in Eye Cheat, a creamy shade that stays put all day long.

If you want to know how to make your eyes look bigger, the formula of your mascara does matter. While we're fans of the clumpy lash trend, Kaye says to steer clear of separating mascaras that give you a spiky look, and instead opt for a volumizing mascara.

Roncal adds that a volumizing mascara will give you long, sexy lashes that really make your eyes stand out. Her secret application tip (well, not so secret anymore): Apply the mascara toward the bridge of your nose and fan your lashes out. And don't even think about applying only one coat -- two are needed to give you that extra volume and oomph.

Discovering how to make your eyes look bigger becomes a lot easier when you add a lash curler to your beauty tools. "Curling your lashes makes a huge difference," says Kaye. "If you do a side by side in the mirror with one side curled and the other side not curled, you can easily see what a dramatic difference it makes."

She says to curl your lashes while they are still wet from your mascara, as this helps them stay in place all day. Because curling your lashes after applying mascara can make them break off -- it's imperative that the mascara should still be wet, not dry.

Makeup not your thing? For eyes that look instantly healthy and larger, up your contact lens prescription to the new 1-Day Acuvue Define (prices start at $65 for one month) lenses. Being in the beauty biz, it takes a lot for a product to elicit shock and awe -- yet, that's exactly what happened when I put them in.

The lenses create a pronounced limbal ring (the outline around the iris), making your eyes appear visually brighter, whiter and more awake," says Kaye. "It's like having magazine-quality retouching for your eyes, but in person."

You can get them with your regular contact lens prescription, or use them purely as a cosmetic enhancement. They come in three effects that complement all eye colors, but you can try Natural Sparkle for blue eyes, Natural Shimmer for hazel/brown eyes and Natural Shine for darker eyes.

1. Prep eyes with a de-puffing eye cream.
2. Brighten the undereye area with a concealer that's one shade lighter than your foundation.
3. Apply a matte nude shadow across your entire lid up to the brow.
4. Use a lighter color with a bit of shimmer (champagne or peach) on the lid.
5. Using a soft, tapered brush, define your crease with a darker shade of eye shadow, such as slate gray or cocoa brown.
6. Dab a highlighter (We like Anastasia Beverly Hills Highlighting Duo Pencil) on the inner corners of your eyes and just beneath the arch of your brow.
7. Tightline your upper lid with a superfine, dark eyeliner to make eyes look bigger and brighter. Use a lighter color on your bottom lid.
8. Rim your lower waterline with white eyeliner.
9. Make eyes stand out with a volumizing mascara that gives you long, separated lashes. Steer clear of the clumpy look.
10. While lashes are still wet with mascara, curl your lashes with an eyelash curler for an instant wide-awake look.
