The Amsler Grid

The Amsler grid was originally developed by Marc Amsler to allow patients to test their own central vision for early signs of macular degeneration, so it may be treated sooner. This test consists of a grid of vertical and horizontal lines.

  1. Look through your reading glasses or bifocals.
  2. Cover the left eye. While looking at the center dot from a distance of 12 inches or so, answer the following questions: Can you see all four corners of the grid? Are any of the lines: blurry, wavy, distorted, bent, gray, or missing?
  3. Repeat the previous step after covering the right eye.
  4. If you note any changes in how you see the grid, call your eyedoctor for evaluation.
  5. We recommend you keep the grid where you can use it 2-3 times a week.
  6. You may print it out, or save it as wallpaper on your computer screen by "right clicking" your mouse button while the cursor is on the grid. Then Left Click "Set As Wallpaper." You can then rearrange your desktop icons around it.
