Hunter Eyes Test
Hunter eyes are not a vibe, they are three measurements: a positive canthal tilt, a narrow vertical eye opening, and a brow that sits close to the eye. Symmi measures all three and tells you which you have.

How it is measured
Three readings, three thresholds.
The tool levels the head, then measures each eye. Tilt is the corner-to-corner angle. Aperture is the vertical opening divided by the horizontal width, so it does not depend on photo scale. Brow distance is the gap from the eyebrow's lower edge to the upper eyelid, divided by eye width. Orbital depth, the fourth thing people mean by hunter eyes, cannot be measured from a flat photo; the app's 3D scan measures it.
- Canthal tilt
- Positive at +2° or more supports the look. On Symmi's scale most faces described as hunter eyes sit between +3° and +6°.
- Aperture ratio
- Height over width. 0.32 or below reads as narrow; 0.40 and above reads as round.
- Brow gap
- Brow-to-lid distance over eye width. Under 0.50 is a low-set brow, the hooded look people call hunter eyes.
- Socket depth
- Not measurable from a 2D photo. Marked as such rather than guessed.
Measure it yourself
How to check for hunter eyes yourself
Hunter eyes are three measurable things. Check each one on a straight-on photo.
- 1Take a straight-on photo at eye level with a relaxed face. Don't smile: a smile pushes up the lower lids and changes the opening.
- 2Tilt: draw a line from the inner corner to the outer corner of each eye and compare it with the line through both pupils. An outer corner that sits higher is a positive tilt.
- 3Opening: measure the eye's height (upper lid to lower lid at the tallest point) and its width (corner to corner). Divide height by width.
- 4Brow gap: measure from the lower edge of the eyebrow down to the upper lid, and divide by the eye's width.
- 5Compare all three with the table below. Hunter eyes means all three land in the hunter column; most people have one or two.

What's normal
Hunter eyes vs prey eyes, by the numbers
Prey eyes are the opposite set: level or downturned corners, a round opening and an open, visible lid.
- Canthal tilt
- Hunter eyes: +2° or more (usually +3° to +6°)
- Prey eyes: Under +2°, or negative
- Opening (height ÷ width)
- Hunter eyes: 0.32 or less: narrow, almond-shaped
- Prey eyes: 0.40 or more: round
- Brow gap (÷ eye width)
- Hunter eyes: Under 0.50: low-set brow, hooded look
- Prey eyes: 0.50 or more: open, visible upper lid
- Socket depth
- Hunter eyes: Deep-set
- Prey eyes: Prominent, forward
Socket depth can't be measured from a flat photo, so the tool leaves it out rather than guessing.

FAQ
What are hunter eyes exactly?+
A set of features, not a single thing: upward-tilted outer corners, a narrow, almond-shaped opening, a brow that sits low over the eye, and deep-set sockets. Most people have one or two of the four. This tool measures three.
Can I get hunter eyes?+
Tilt and orbit are bone. Aperture and brow position have a soft-tissue component: the orbicularis and the brow depressors respond to training, and a lower brow narrows the apparent opening. The Symmi app builds that routine and tracks the readings between scans.
Why does the app say something different from a looksmaxxing forum?+
Forums rate from a photo by eye. This measures. The two disagree most on canthal tilt, where landmark measurement reads a few degrees lower than what people quote.
Is my photo uploaded?+
