Look at each dotted circle and type the number you can see. Some plates genuinely have no number — for those, answer nothing.
Do it on a decent screen at normal brightness, without a colour filter or night shift on. This is a bit of fun and a rough guide — it is not a medical test and it is not a diagnosis.

Rough guide only. Plates are generated in your browser, so this is screening-shaped fun rather than a calibrated clinical test — if the result surprises you, see an optometrist.
