Amsler Grid
You eye doctor may provide you with a small paper chart that has crossed lines printed on it called an Amsler Grid. This grid can be used at home so that you may test yourself to find early, subtle changes in your vision. If you notice any sudden change in your vision, especially distortion, you should contact your eye doctor immediately. To download an Amsler Grid go to Prevent Blindness America's Age-Related Macular Degeneration Test.
