What is Vision Test Snellen?

Vision Test Snellen displays a standard Snellen eye chart on your screen for a quick visual acuity self-check. While it doesn't replace a professional eye exam, it helps you gauge whether your vision has changed and if you should visit an optometrist.

How to use

1. Step 1 — Sit at the recommended distance from your screen (typically arm's length or 20 inches).
2. Step 2 — Read each row of letters starting from the top, covering one eye at a time.
3. Step 3 — Note the smallest row you can read clearly to estimate your visual acuity level.

Result

You notice difficulty reading signs while driving. Open the Snellen chart, sit 20 inches from screen, cover your left eye and read down — you can only read to the 20/40 line, suggesting it's time for an eye exam.
