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

Under-eye darkness (ΔL*), eye openness and canthal tilt — the parts of the orbit a photo can read — scored and placed on the masculinity axis.

What we report

Under-eye darkness (ΔL*), eye openness and canthal tilt — the parts of the orbit a photo can read — scored and placed on the masculinity axis.

Why not the clinical number itself

Defined in lateral view as the sagittal relationship of the cornea to the inferior orbital RIM — a bony structure. It cannot be computed from a frontal photo at all, and from a lateral photo only as a soft-tissue proxy. The clearest example of a metric consumer tools claim and provably cannot measure.

What we measure instead

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