What is an Amsler grid?
An Amsler grid is a chart that you can use to test your eyes for a
change in central vision. The test is simple and can be done
quickly at home. It is often recommended for people with macular
degeneration. This is damage to the part of the eye that allows
you to see detail in the center of your vision. Regularly checking
your vision with an Amsler grid can help you to find changes in
your vision. If you find a change, you need to see your eye doctor
as soon as possible.
How is it used?
Hold a copy of the grid in good light at your normal reading
distance (usually about 12 inches). If you usually wear glasses to
read, put them on.
Completely cover one eye with the palm of your hand and look
directly at the small black dot in the center of the grid. All of
the lines should look straight and clear. If any of the lines look
blurred or wavy, or if some lines are missing, mark that on the
grid. Then cover the other eye and repeat the test.
If your doctor recommends it, take the test every day.
Keep the grid in a convenient place. Look for any change in the
appearance of the lines and boxes on the chart since the last time
you took the test. If you notice a change, call your doctor for an
appointment right away.
