Orbital vector / infraorbital rim position
what a photo can give, and how we take it.

The parts of the eye socket a photo can actually read: under-eye darkness (ΔL*), eye openness and canthal tilt. Each is scored and placed on the masculinity axis.

Also searched as negative orbital vector, positive orbital vector, under-eye support and infraorbital rim.

What we report

The parts of the eye socket a photo can actually read: under-eye darkness (ΔL*), eye openness and canthal tilt. Each is scored and placed on the masculinity axis.

globeinferior orbital rim:bone, under the cheekorbital vector:front of cornea to rimdefined in lateral view. a lateral photogives a soft-tissue proxy for the rim
The orbital vector is the front of the cornea against the inferior orbital rim, seen from the side. The rim is bone under the cheek, so a lateral photo gives only a soft-tissue proxy for it.

Why not the clinical number itself

Defined in lateral view as the sagittal relationship of the cornea to the inferior orbital RIM. The rim is bone. A frontal photo cannot compute it at all, and a lateral photo gives only a soft-tissue proxy. Of everything consumer tools claim, this is the clearest example of a measurement they provably cannot make.

What we measure instead

Ratios of near-coplanar frontal distances, angles relative to the interpupillary line, and skin appearance. Each comes with an error bar, and each is placed against a population you choose. Start an analysis or read the methodology.

Same question, different measurement: what the clinical version needs, and what a photograph can give instead.
