A quick word about these tests.
These are informal screening tools, not medical diagnostics. They run on your own screen, at your own distance, under your own lighting — all of which vary. If a test suggests something might be off, the right next step is a full consultation in clinic. If every test says you're fine, keep your regular check-ups anyway.
Visual acuity
A calibrated Snellen chart. Calibrate your screen once with a credit card, then read the rows aloud from arm's length.

A radial sunburst pattern. With one eye closed, check whether any of the lines look noticeably darker or sharper than the others.
