Visual acuity test

A well-lit area at least 10 feet long is needed for the distance vision test. You will need measuring tape or yardstick, eye charts, tape or tacks to hang the eye charts on the wall, pencil to record results, and -- if possible -- another person to help. The vision chart needs to be tacked to the wall at eye level. Mark the floor with a piece of tape exactly 10 feet from the wall where the chart is.

The tests cause no discomfort.

Vision may change gradually, and you adjust to the change without being aware of it. Home vision tests are useful in early detection of eye and vision problems. Perform home vision tests every year. Many people at risk for macular degeneration may be told by their ophthalmologist to perform the Amsler grid test more frequently.
