How to test yourself for signs of Age-related Macular Degeneration using an Amsler Chart

The Amsler chart is a tool that eye doctors use to detect vision problems (specifically, Age-related Macular Degeneration).
Early diagnosis means early treatment, so it may help to limit or at least slow the vision loss you experience.
If you are at risk for macular degeneration or other eye diseases, you can use this chart at home to monitor your vision. But using the chart doesn’t mean you should skip regular visits to your eye doctor because you can easily miss signs that only a trained eye care practitioner will find.
