How much white shows below the iris, and whether the whites look red or yellow.
How it's assessed
Each item here is checked as a visible condition and answered none, mild, moderate or severe. If it can't be seen in your photo, the answer is none, and most healthy adults show none for most items. The full explanation is on the Features overview.
This is a photo-based estimate for general interest, not a diagnosis or medical advice. If something concerns you, ask a doctor or dermatologist.
Sclera Show
How much white is visible between the iris and the lower eyelid or above the iris. A thin visible rim below the iris can read as an intense, wide-eyed look; the grade reflects how much white is visible when your eyes are relaxed and open.
Sclera Reddening
Red or bloodshot whites of the eyes. Tiredness, dryness, irritation and allergies all cause it. Camera flash and warm light also add redness.
Sclera Yellowing
A yellow tint to the whites of the eyes. Lighting and photo colour balance can make whites look yellowish, so use neutral daylight. Persistent yellowing in real life can have medical causes and is worth raising with a doctor.
