Why It Matters
Eye spacing can influence how balanced the eye area feels relative to the whole face. It is best read together with eye shape, canthal tilt, and facial width.
How It Is Calculated
The test measures interpupillary distance between both pupil landmarks and divides it by the bizygomatic face width between cheek-edge landmarks.
