Positive, near-level, and negative canthal tilt compared by geometry
	Negative	Near level	Positive
Outer corner	Lower than the inner corner	Close to the same height	Higher than the inner corner
Angle	Less than 0°	Either sign, small	Greater than 0°
Direction	Below −2°	From −2° through +2°	Above +2°
Photo sensitivity	Roll against the photo edge can fake it	A tenth of a degree can cross zero	Pitch and yaw still move it

None of the three is a target, a flaw, or a health finding. Read positive, negative, and near level. The manual steps are on how to measure.

Measure from a front-facing photo. The signed degrees come first.
