Blink rate	—	/min (healthy 12–20)

Incomplete blinks	—	(target < 10%)
TBUT (NIBUT proxy)	—	(healthy ≥ 10s)

Screening estimate from consumer-grade video — not a medical diagnosis. TBUT here is a non-invasive proxy (texture stability) and is not equivalent to fluorescein TBUT measured at a slit lamp. Consult an eye-care professional for evaluation.

Recording tips for best results

20–60 seconds of recording, well-lit, with the subject's eyes clearly visible.
Camera roughly at eye level, fairly close (a face filling 30–60% of the frame works well).
Subject looks at the lens and blinks naturally. Include a few "eyes-open" stretches of several seconds so TBUT can be measured between blinks.
Avoid heavy glasses glare or extreme backlight.
