Eye area guide
Learn what canthal tilt means, how eye angles are measured, and why camera angle can change how your eye area appears.
Canthal tilt is the angle between your inner and outer eye corners. If the outer corner sits higher, it is often called positive tilt. If both corners are near level, it is neutral tilt. If the outer corner sits lower, it is negative tilt.
The model detects eye reference points, estimates each eye corner position, and computes an angle in degrees. It also checks left-right consistency, because symmetry affects how stable the result appears from photo to photo.
Eye-angle readings are sensitive to yaw, roll, camera height, and expression tension around the eyes. For better consistency, use a front-facing frame, level head posture, and even lighting, then compare multiple tests instead of trusting a single snapshot.
Start with canthal tilt test for a static result, then use live face rating to see how posture changes the eye-angle signal in real time.
Measure canthal tilt, check eye balance, or test live presentation.
