Eyes · guide + free test
The difference is three measurements, not a vibe: how the outer corner sits, how open the eye is, and how close the brow rides. Here are both, side by side, with the numbers that separate them and a test for your own.


Hunter eyes
Positive tilt · narrow opening · low brow · hooded lid


Prey eyes
Round opening · high brow · exposed lid · softer tilt
Both faces are AI-generated to show the two eye areas on otherwise similar faces. Nobody real is being rated.
What actually differs
| Trait | Hunter | Prey |
|---|---|---|
| Canthal tilt | Positive: outer corner higher than the inner, roughly +2° to +8° | Neutral or negative: outer corner level with or below the inner, about −4° to +2° |
| Eye opening (height ÷ width) | Narrow, almond: 0.32 or less | Round, open: 0.38 or more |
| Brow position | Low and straight, close to the eye | High and arched, well above the eye |
| Upper eyelid | Hooded, little or no lid skin showing | Exposed, a clear band of lid skin |
| Eye socket | Deep-set under a strong brow ridge | Shallow, the eye sits forward |
| Reads as | Focused, intense, older | Open, approachable, younger |
The first three rows are what the test below measures. Socket depth needs a 3D scan, and the last two rows are how people read the first four. Thresholds are Symmi's landmark scale, which reads canthal tilt a few degrees lower than calliper measurements quoted on forums.

Bone vs trainable
Two of the three readings are anchored in bone. The canthal tilt is set by where the orbit puts the corners of the eye, and socket depth is the orbit itself; neither moves without surgery. The brow and the lid are different. The brow sits where the frontalis and the brow depressors hold it, and a brow held high from habit can settle lower with training. Puffiness above the lid, from fluid, sleep or salt, hides the hooded look and clears with the morning routine. So the honest answer is: the tilt is yours for life, the brow gap and the apparent opening can move a little, and the app tells you which of your three readings is which before you spend time on any of them.
FAQ
Prey eyes is the looksmaxxing term for round, open eyes with a neutral or slightly negative canthal tilt, a high brow and visible upper eyelid. The name comes from the idea that prey animals have wide, forward-open eyes for spotting danger, while predators have narrow, hooded ones. It is slang, not anatomy, but the three features it points at are real and measurable.
No. Hunter eyes read as intense and are the current looksmaxxing ideal; prey eyes read as friendly and are the older beauty ideal, especially for women. A large share of famous faces sit on the prey side. What matters for how a face reads is the whole set, not one feature.
Most people are a mix: a positive tilt with a round opening, or a hooded lid with a high brow. The tool above measures the three readings on your photo and tells you which of them fall on the hunter side. Two or three out of three is a hunter-leaning eye area; zero or one is prey-leaning.
The bone cannot change: canthal tilt and socket depth are set by the orbit. The brow and the lid have a soft-tissue component. A brow that sits high partly from habit can settle lower with training, and puffiness above the lid can hide the hooded look. Those two readings can move a little; the tilt will not.
Forum ratings are done by eye, from photos taken at different distances and angles. This page measures landmark to landmark after removing head tilt. The measured tilt also reads a few degrees lower than the numbers people quote, because it uses the true corner points rather than the eyelid margin.
