Test build — not a diagnosis. This estimates whether an eye photo
looks worth an optometry visit. Always see a professional about symptoms. Privacy: only the eye area inside the oval is ever uploaded — the full camera view
stays on your device, and images are processed in memory, never stored.
Keep your eyes on this line and read along naturally. The quick brown fox jumps over the
lazy dog while the calm gray cat watches from the windowsill. Blink as you normally would —
do not force or hold back your blinks. Reading on a screen often makes people blink less
than usual, which is exactly what this little test is trying to measure.

The blink test runs entirely on your device — no video is ever uploaded.
Sit at normal screen distance so the camera can see your whole face.
