This is not a replacement for a professional eye exam: the best way to protect your eyes is by getting regular exams from an optometrist.
In between visits, or just to see how you’re doing, you can give yourself a self-checkup. This is not as accurate or as in-depth as what your optometrist would have you do, but it is a practical way to gauge how your eyesight is. You can do this with a friend if you want, and together help each other find out how good your vision is.
- Print out a Snellen Eye Chart (opens to new window)
- Tape it to a wall, about four feet off the floor
- Sit in a chair about 10 feet from the wall. If you regularly wear glasses or contact lenses, you should wear them for the test to gauge how they are working for you.
- Cover one of your eyes, using a handkerchief or something to block the vision of that eye. Have a friend use a flashlight to point at the chart. Starting at the top and keeping both eyes open, follow the flashlight, reading each letter as they are highlighted.
- Record the number of the smallest line you can read correctly (for example, 20/20)
- Do the test again for the other eye
