Blurry Areas and Black Spots Wavy or Crooked Lines
Proper use of the grid will enable you to detect very subtle changes in your vision which can occur when there is just a small amount of fluid under your retina. To perform the test properly, wear the glasses that you normally wear for reading. If you wear bifocals, use the bottom portion or reading portion of the glass. Attach the Amsler's Chart to a wall at eye level and stand 12"-14" (comfortable reading distance) away from it. Cover one eye. With the other eye, look at the center dot. The first day you observe the grid, mark with a pencil any areas of distortion, any gray or blurry areas, or any blank spots. This will be your baseline pattern.
Each and every morning thereafter, look at the center dot of the Amsler's Chart. If you notice new areas of distortion, wavy lines instead of straight lines, or enlargement of the blank spots, especially towards the center, you should call your ophthalmologist and arrange for an appointment as soon as possible.
f you are over the age of 45 or if your family has a history of retinal problems such as macular degeneration, you should have your eyes checked periodically.
Your ophthalmologist or optometrist will examine your eyes with an ophthalmoscope to see if damage is present in the macula. Should macular degeneration be apparent, further tests will be done. These include the Amsler's Chart.
How To Test Yourself With the Amsler Grid
If you need reading glasses, please wear them while you use the Amsler grid. The grid should be at about the same distance from your eyes that any other reading material would be.

Cover one eye, then focus on the dot in the center.
• Do any of the lines look wavy, blurred or distorted? (All lines should be straight, all intersections should form right angles and all the squares should be the same size.)
• Are there any missing areas or dark areas in the grid? • Can you see all corners and sides of the grid? • Don’t forget to test both eyes.
VERY IMPORTANT: Report any irregularity to your eye doctor immediately. You can mark areas of the chart that you’re not seeing properly and bring it with you to your eye exam.
