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.
How under-eye support is measured
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.
Ratios, ranges & 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.
