Vision Checker

Wearing your glasses (if you need them to work at your computer), position yourself so the screen is in focus. Cover one eye and look at the center dot with the other.

If the lines look irregular (wavy, blurred, gaps or discolored), contact your eye care physician.

Repeat with the other eye.

Snellen Eye Chart

View at 20 feet or change the first number to your viewing distance. For example,
if you view the chart from 10 feet, the 20/50 row becomes 10/50, which is actually 20/100.
The height of the 20/50 row should be 7/8".
