Hunter eyes is an internet coinage, not a clinical term, and the four features usually listed for it are not equally checkable. Three are numbers you can get off a single photo. The fourth needs depth that a flat photo does not carry. Here is each one, what it means, and how to measure it.
Where the term comes from
Hunter eyes is a looksmaxxing coinage. It appears in no anatomy reference and no clinical measurement carries the name. It travels as one half of a pair — hunter eyes against prey eyes — and the pair is where its force comes from: one end is described as focused and assessing, the other as round, exposed and reactive.
That matters here for one practical reason. Because nobody owns the definition, the list of features shifts between the pages that describe it. What follows is the version that appears on nearly all of them, taken apart one feature at a time.
Which of the four are actually numbers
Three of the four have a definition you can put a number on. One does not, and it happens to be the one doing most of the work in the descriptions.
The four features, and which of them are numbers
Feature
Measurable from one photo?
What the number actually is
Positive canthal tilt
Yes — in degrees
The angle from the inner eye corner to the outer one, against the horizontal. On this site 2° and above is the positive band.
Low eyelid exposure (hooded)
Yes — as a ratio
Eye opening height divided by eye width. The scan on this site compares yours against a reference of 0.34; the faces it has measured mostly land between 0.22 and 0.39.
Almond, horizontally long shape
Partly
This is the same ratio read the other way round. A low aperture ratio is what long-and-narrow-rather-than-round means numerically — there is no separate measurement for it.
Deep-set, with a strong brow ridge
No
This one is depth. A single flat photograph does not carry depth, and the shadow that reads as depth is made mostly by your lighting.
The one a photo cannot give you
Deep-set is not measurable from a single image. Depth needs either two viewpoints or a depth sensor. What one photograph carries instead is shadow — and shadow is mostly your lighting. A lamp above and slightly in front of you sinks the eyes and darkens the crease. Flat frontal light fills the socket and removes both. The same face photographed twice ten minutes apart can read deep-set in one frame and not in the other.
So when an app tells you your eyes are deep-set, or a page shows you a before and after, look at the light before you accept the verdict. It is the same failure described on negative canthal tilt, where camera height alone moves the measured angle by more than the width of a whole band.
How to check the two you can check
Canthal tilt, in degrees
Run the canthal tilt test with the lens level with your eyes and your chin neutral. It reports each eye separately and draws the measured lines on your own photo, so you can see where the corners were placed. Two degrees and above is the band these descriptions are pointing at — and published adult measurements cluster right around there, which is worth knowing before you treat a positive tilt as rare.
Eyelid exposure, as a ratio
The full scan measures your eye opening height against your eye width and scores it against a reference of 0.34. A lower ratio is what hooded means numerically. The scan prints the arithmetic next to the score, so you can check it rather than take it.
Then do it twice
Both numbers move with head pitch and camera height by more than the difference these descriptions are drawing. Two photos taken in separate sessions and compared against each other will tell you more than one photo compared against a stranger's list.
What neither number tells you
Whether it looks good. Nothing measured on this site is a verdict, and the intensity of feeling this vocabulary attracts online is not evidence that the categories behind it are real.
Hunter eyes and prey eyes
The pairing is the whole point, and it is worth separating the two things it does. As a description of two ends of a range it is unobjectionable: eyes genuinely vary in tilt and in how much lid shows, and the two ends look different. As a sorting into types it is doing something else, because almost everyone measures somewhere in the middle on both axes rather than at an end.
If your tilt came out below the positive band, negative canthal tilt goes through what sets the angle and what changes it. If it came out close to level, neutral canthal tilt is the most common result by a wide margin — which is itself an answer to the question people usually arrive with.
Can you get them?
Two of the four features are bone. The canthal tilt is set by the orbital rim and the height at which the outer corner attaches to it; the brow ridge is the brow ridge. Neither responds to exercises, mewing or massage, and what moves a canthal tilt and what does not goes through the evidence on each of those claims one at a time.
What does change is the impression. Brow shape, the direction the light comes from and the height of the camera all move how the eye area reads, and they move it by a lot. That is a real effect and worth knowing. It is also a different claim from having changed your face, and the pages that blur the two are usually selling something.
Where to go next
Canthal tilt test — the angle for each eye, in degrees, with the measured lines drawn on your photo.
Positive canthal tilt — the band these descriptions are aiming at, and how common it actually is.
Negative canthal tilt — what sets the angle, and why your own photos disagree with each other.
A looksmaxxing term for an eye area that is deep-set under a prominent brow ridge, hooded so that little upper lid shows, horizontally long rather than round, and tilted so the outer corner sits above the inner one. It is not an anatomical or clinical term and no published measurement carries the name, so the exact list of features varies between the pages that describe it.
Is hunter eyes a real medical term?
No. It does not appear in anatomy or ophthalmology references and no clinical measurement is named after it. The individual components are real and measurable — canthal tilt and eyelid exposure both have standard definitions — but the grouping of them under this name comes from online forums, not from any published literature.
How do I know if I have hunter eyes?
You can measure two of the four features. Run the canthal tilt test for the angle in degrees, and the full scan for your eyelid exposure ratio. The third feature, an almond shape, is the same ratio read differently. The fourth, being deep-set, cannot be measured from a flat photo at all, because depth needs either two viewpoints or a depth sensor. Any page or app that gives you a confident verdict on that fourth one from a single selfie is reading your lighting.
What is the difference between hunter eyes and prey eyes?
Prey eyes is the label used for the opposite end of the same axes: rounder, more visible upper lid, and a neutral or negative canthal tilt. As a description of two ends of a range it is unremarkable, because eyes really do vary that way. As two types you get sorted into it is misleading, because most people measure somewhere in the middle on both.
Can you get hunter eyes naturally?
Not the structural parts. The canthal tilt is set by the bony orbital rim and the height at which the outer corner attaches to it, and the brow ridge is bone. Neither responds to exercises, mewing or massage. What does change is the impression: brow shape, lighting direction and camera height all move how the eye area reads, sometimes by more than the difference the descriptions are drawing.

Measure the parts that are measurable
The canthal tilt test gives you the angle in degrees for each eye. The full scan reports your eyelid exposure against a reference value. Both run in your browser and nothing is uploaded.
Front-facing, unobstructed, evenly lit photos work best. Your photo is analysed on your phone or computer and is never uploaded.
