If you are at risk for vision loss, you may be told to check your eyesight regularly using the Amsler grid. Below is the grid and instructions for using it.

1. Use the grid in a well-lighted area.
2. Wear glasses or contact lenses if you often wear them. If you are wearing bifocals, look through the part of the lens for near vision.
3. Hold the grid at your normal reading distance (about 16 inches).
4. Cover your left eye.
5. With your right eye, look at the dot in the middle of the grid. You should still be able to see all 4 corners of the grid.
6. While looking at the dot, notice if:
   • Any lines look wavy
   • Any lines disappear
   • The boxes change shape or are missing
7. Keep a log with the dates you used the grid. Write down any vision changes from the last time you used it.
8. Now do this again. This time, cover your right eye.
9. Call your doctor right away if you notice any vision changes.

Use the Amsler grid as often as your eye doctor advises. Keep the grid and the log where you'll remember to use them. Some people put the grid on their fridge door. Call your eye doctor right away if you notice any changes with your eyesight. This includes if your vision gets better.
