FAQ
Is this vision test accurate?
This tool provides a basic screening using standard Snellen and Tumbling E charts. It is not a replacement for a professional eye exam. For accurate results, visit an optometrist.
Does this tool work on mobile?
Yes, the chart adapts to your screen size. For best accuracy, use a desktop browser at the recommended testing distance.
