FORMA FEATURE / EYES & ORBIT

Eyelids & eye aperture: measurements, ratios, and research

Eye aperture is the opening between the lids. Upper-lid exposure, lid crease, globe prominence, and lower-lid position are separate features.

How eyelids & eye aperture is measured

Eye aspect ratio = inner-to-outer corner width ÷ vertical opening through the pupil. Upper-lid show measures visible skin below the crease, not the entire brow-to-eye distance.

Lower lid at the iris — Scleral show in one selected sample

None of the 42 selected celebrities in the 2023 study showed white sclera below the iris.

Observation: A small selected sample and a single expression per photo cannot prove zero lower scleral show is universally optimal. Using Artificial Intelligence to Quantify Sexual Dimorphism in Aesthetic Faces

3 : 1 — A forum eye-shape claim

A forum poster describes Jeremy Meeks as having a 3:1 eye aspect ratio.

Forum claim: Not independently measured. Squinting, gaze, expression, and camera position can substantially change this ratio. Discussion of Jeremy Meeks’ canthal tilt

Practical takeaway

Read a supported lower lid and relaxed eye opening.

A lower lid meeting the lower iris is the concrete appearance illustrated by the selected sample. Evaluate upper-lid exposure separately from the width-to-height opening.

What changes the answer

Gaze, squinting, globe prominence, and brow position alter these measurements. Naturally hooded and more exposed upper lids need different comparisons; forcing a squint does not measure resting shape.
