Remote visual acuity is a way to measure how well you see at distance using a chart on a phone, tablet, or computer. You follow set steps for distance, screen size, and lighting. The result is a rough snapshot, not a full eye exam. An in-clinic test is still needed for a full prescription and eye health check.

You cover one eye, read the smallest line you can, then repeat with the other eye. Some tests ask you to step back a set distance and keep your head still. Your score is based on the smallest line you can read correctly.
Use a screen that is large enough to show the chart without zooming. Stand or sit at the exact distance the test asks for and keep the lighting steady. Wear your usual glasses or contacts if the test is checking your best corrected vision. Avoid glare on the screen because it can hide letters.
Remote tests can miss issues like dry eye, cataracts, and retina problems that change vision. Small screens and wrong distance can make results look worse than reality. It also cannot measure eye pressure or check eye health. If vision changes fast or feels uneven between eyes, an in-person visit matters.
Clean the screen, turn off night mode, and set brightness to a normal level. Cover one eye without pressing on it, since pressure can blur vision. Take the test more than once and average the result if the score jumps around. If you catch yourself memorizing letters, stop and restart later.
It can be close when the setup is correct and the chart is scaled the right way. Small setup errors can change results a lot. Treat it as a screening tool, not a final answer.
Yes, if you want to check vision with your usual correction. Use fresh lenses and avoid testing right after putting drops in. If you test without correction, expect a lower score.
No. An eye exam checks prescription and eye health, which a screen test cannot do. Use a remote test to track changes, then book an exam if results drop.
Retest with the same distance, lighting, and no screen zoom. If the drop is real, book an eye exam soon. Get urgent care for flashes, a curtain-like shadow, or sudden vision loss.
