Canthal tilt

Canthal tilt describes the angle of the eye. Draw a line from the inner corner (the medial canthus) to the outer corner (the lateral canthus) and compare it with a horizontal line: the angle between them is the tilt. It is one of the most discussed measures in looksmaxxing, mostly because of its association with hunter eyes.

Positive, neutral and negative

• Positive — the outer corner sits higher than the inner one. A slight positive tilt is common in adults.
• Neutral — the two corners sit level.
• Negative — the outer corner sits lower than the inner one.

The angles involved are small, usually a few degrees either way. Tilt varies naturally with ancestry, and the outer corners tend to settle slightly lower with age. None of the three is a defect; they are variations in how eyes are shaped.

What it actually measures

Tilt measures one line on a face that is read as a whole. How an eye area comes across depends at least as much on things the angle does not capture: the brow and how low it sits, how much upper eyelid shows, the under-eye area, expression, and whether you slept. A photograph also distorts the angle easily. Tilting the head, a camera held above or below eye level, or a smile lifting the cheeks all change the apparent tilt, which is why measurements taken from casual photos disagree with each other.

What the scan measures

The free face scan reads canthal tilt from facial landmarks on a square-on frame, alongside fWHR, symmetry and eye spacing, all on your device. It counts toward the frame score, which describes structure that is set in adults, and none of the product recommendations attach to it. That is deliberate: nothing in a bottle changes the angle of an eye.

Can it change?

Not without surgery. Eyelid procedures such as canthoplasty exist, and they carry real risks — dryness, scarring, asymmetry, a result that does not look natural. That is a conversation for an oculoplastic surgeon, not a forum. The longer look at what the eye-area vocabulary does and does not mean is canthal tilt and hunter eyes.

What is changeable

The angle is fixed; what surrounds it is not. Dark circles, puffiness and under-eye texture change how rested and alert the eyes look far more than a degree of tilt does, and they respond to sleep and a simple eye-area routine. Tidy, unforced brows frame the eye; heavily shaped ones fight it. The practical version is dark circles and eye bags.
