You’ve probably spent way too long staring into a bathroom mirror, tilting your head, and trying to figure out if your lids are "hooded" or if you just didn't get enough sleep. It’s a thing. Most of us just assume we have "normal" eyes, whatever that means. But the truth is that understanding the different shapes of eye isn't just about vanity or winning at winged eyeliner. It’s actually about geometry. Honestly, your eye shape dictates how light hits your face, how you age, and even how certain optometric frames sit on your nose.
It’s weirdly complex.
Look at any professional makeup artist's kit—like Pat McGrath or Hung Vanngo—and you’ll see they don't treat every face the same. They can’t. Because an almond eye interacts with a shadow palette completely differently than a prominent or deep-set eye. If you’ve ever followed a YouTube tutorial and ended up looking like a raccoon instead of a supermodel, it’s probably because you were following instructions meant for a different bone structure. We’re going to break down the actual science of these shapes, the "pencil test" trick, and why the angle of your lateral canthus—that's the outer corner of your eye—is the real secret to identifying your look.
The Almond Eye Standard (and Why It’s Not the Only Goal)
Almond eyes are basically the "oval face shape" of the eye world. They are symmetrical, usually have a visible crease, and the iris touches both the top and bottom eyelids. You won't see any white (sclera) above or below the iris when looking straight ahead. Think Beyoncé or Mila Kunis.
But here’s the kicker: just because they are considered the "balanced" shape doesn’t mean they’re better. They just have the most real estate for pigment. If you have almond eyes, your primary goal is usually just maintaining that natural lift.
What to Look For
Take a photo of yourself looking dead-on at the camera. If your eyelids taper at the inner and outer corners but stay wide in the middle, you're in the almond club. It’s a classic shape. Simple.
Hooded Eyes vs. The "Brow Drop"
This is where people get confused. Hooded eyes are characterized by a fold of skin that hangs over the crease, making the eyelid itself look smaller or disappearing entirely when the eyes are open. Some people are born with them—like Jennifer Lawrence or Blake Lively—while others "develop" them as the brow ridge loses elasticity over time.

It isn't a flaw. It’s just a different canvas.
The biggest struggle here is the "disappearing act." You spend twenty minutes blending a perfect gradient, you open your eyes, and poof. It’s gone. If you have hooded eyes, you basically have to apply your makeup with your eyes open. If you close them to apply shadow, you’re guessing where the fold will land. You have to go higher than you think. You’re essentially painting a new crease onto the brow bone itself.
The Genetics of the Hood
Research in Nature Communications has actually looked into the genetic clusters that determine eyelid folds, particularly the EDAR gene, which is prevalent in East Asian populations and leads to the monolid (a variation of the hooded look where the crease is absent). However, hooded eyes appear across every single ethnicity. It’s about the prominence of the supraorbital ridge.
Round Eyes and the Sclera Secret
If you can see white space under your iris when you’re looking straight ahead, you’ve got round eyes. They are usually large, bright, and very expressive. Think Zooey Deschanel.
Round eyes are great because they look "awake" naturally. The downside? They can sometimes look "startled" if you use too much light-reflecting makeup on the inner corners. To balance them out, many people use dark liner on the waterline to "shrink" the vertical height and stretch the eye horizontally.
- The Test: Look in the mirror. Relax your face.
- The Result: Is there white visible below the colored part of your eye? If yes, you’re round.
- The Nuance: Sometimes a "round" eye is actually a "prominent" eye, meaning the eyeball itself sits further forward in the socket.
The Tilt: Upturned and Downturned Dynamics
This has nothing to do with the lid and everything to do with the axis. This is where the different shapes of eye get technical.
Imagine a horizontal line running straight across your pupils.
If the outer corners of your eyes flick up above that line, you’re upturned. This is often called a "cat-eye" shape naturally. Kendall Jenner is the poster child for this, often emphasizing it with "fox eye" lifting techniques. It gives a natural lift to the face.
Downturned eyes are the opposite. The outer corners drop slightly below the level of the inner corners. Now, for some reason, people think "downturned" sounds negative. It shouldn’t. Anne Hathaway and Katy Perry have downturned eyes, and it gives them a "bedroom eye" or "doe-eyed" look that is incredibly soulful. The trick with downturned eyes is to avoid dragging eyeliner all the way to the end of the lash line, which can emphasize the "droop." Instead, stop the liner a few millimeters early and flick it up.
Monolids and the Beauty of a Smooth Surface
Monolids (or epicanthic folds) are characterized by a lack of a visible crease. The skin from the brow flows straight down to the lash line. This is a stunning, flat surface that acts as a perfect playground for bold, graphic liners and high-pigment shadows.
A common misconception is that you need to "create" a fake crease with contour. You don't. In fact, many modern editorial looks specifically highlight the smoothness of the monolid. The key here is vertical blending—gradients that go from dark at the lash line to light as they move toward the brow—rather than horizontal "crease" work.
Deep-Set vs. Prominent: The 3D Factor
This is about the Z-axis. How deep does the eye sit in the skull?
- Deep-Set: Your eyes are tucked further back into the socket. This usually means your brow bone is quite prominent, casting a shadow over your eyes. It gives a very intense, mysterious look. Think Julianne Moore. Because your eyes are already in shadow, you want to avoid dark, smoky colors that make them "recede" even further. Bright, shimmering tones are your best friend.
- Prominent: These eyes sit forward. They are the focal point of the face. You have a lot of eyelid space to work with. Darker shades work beautifully here because they help "push" the eye back visually, creating a more balanced profile.
The Impact of Aging on Eye Shape
Shapes change. Gravity is a real thing.
As we age, the fat pads in our eyelids can shift or diminish. This leads to "hollowing" in deep-set eyes or increased "hooding" in almond eyes. This is why your makeup routine at 20 shouldn't be your routine at 50. The skin on the eyelid is the thinnest on the entire body. It loses collagen faster than your cheeks or forehead.
Using peptides and retinols specifically formulated for the eye area can help maintain the "snap" of the skin, but ultimately, the bone structure remains the same. Understanding your base shape helps you adapt as the years go by.

How to Precisely Identify Your Shape Right Now
Don't just guess. Use the "Elimination Method."
First, check for a crease. No crease? You have monolids.
Second, if you have a crease, look at your iris. If you see white above or below it, you are round. If the iris is partially covered by both lids, you are almond.
Third, look at the outer corners. Do they flick up? Upturned. Do they dip down? Downturned.
Finally, look at your crease when your eyes are open. Does the skin of your brow cover the crease? You are hooded.
You can be a combination. You might have "round, hooded eyes" or "upturned, deep-set eyes." It’s a matrix, not a single box.
Actionable Steps for Your Eye Shape
Knowing your shape is useless unless you do something with it.
For Hooded Eyes: Invest in a high-quality eye primer. Because the skin folds over itself, oils get trapped, and shadow smudges instantly. Use "batwing" eyeliner techniques where you draw the wing with your eye open so the line stays straight across the fold.
For Round Eyes: Focus on the outer thirds. Apply mascara and liner only to the outer corners to "pull" the eye outward into a more elongated shape.
For Monolids: Embrace the "floating liner" trend. Since you don't have a crease to break up the line, you can draw sharp, geometric shapes that stay perfectly crisp.
For Downturned Eyes: Focus on the "upward 45." When applying shadow or liner, imagine a line connecting the end of your nose to the end of your eyebrow. Never let your makeup dip below that line.

Stop fighting your natural geometry. Once you stop trying to make your eyes look like someone else's, you'll realize that the different shapes of eye are what actually give a face its character. Clean your mirror, grab a liner, and start working with the angles you actually have. Check your local optician for "Asian fit" or "Low bridge" glasses if you have monolids or a flatter bridge, as these are specifically engineered for those bone structures. Balance your brow shape to your eye shape—arched brows for round eyes, straighter brows for hooded eyes—to create the most cohesive look.
