FORMA FEATURE / EYES & ORBITUnder-eye support: measurements, ratios, and research
The lower orbital rim and cheek tissues support the lower eyelid. The tear trough is a surface contour; it is not the same structure as the bony rim. This page separates published measurements from interpretation, preference experiments, and community speculation.
What under-eye support means
In profile, compare the forward position of the globe with the rim/cheek support below it. A negative vector means the globe projects farther forward. This needs a clinical assessment, not a selfie diagnosis.
Facial measurements only become comparable when the view, head position, soft-tissue landmarks, and endpoint definitions are held constant. A number copied from a profile photograph is not interchangeable with a value measured from a clinical scan or a front-facing portrait.
Official measurements, ratios & competing claims
Vector, not a ratio Globe–rim relationship
An anatomical study found that a negative globe-to-rim vector becomes more common with age and matters when assessing lower-eyelid surgery.
Clinical anatomy: The study concerns anatomy and surgical planning, not a validated attractiveness cutoff. Changes in ocular globe-to-orbital rim position with age
Practical takeaway
Compare the eye’s projection with the support beneath it.
Use the globe–rim relationship to describe whether the under-eye support sits behind, approximately level with, or ahead of the eye. Then examine the lid-to-cheek transition separately.
What changes the answer
A tear-trough shadow can reflect contour, lighting, or surface coloration; it does not establish the bony vector. Cheek projection and globe position must be assessed together. This is anatomical guidance, not an attractiveness cutoff.
Use these ranges to ask a better question about proportion—not to grade a face or choose a procedure by number alone. A qualified clinician still needs to examine function, tissue, skeletal structure, and your goals in person.
