Amsler Grid
If you have macular degeneration, a simple, daily routine that takes less than one minute can help save more of your vision.
Vision in people with AMD usually diminishes gradually, so they may not be aware of how much sight they have lost. That’s why they can use a special testing tool called an Amsler grid to check their eyesight every day. Using this grid is essential to finding any vision changes that are not obvious.
Use the grid once a day, every day.
The Amsler grid is a simple square containing a grid pattern and a dot in the middle. This design, when used correctly, can show problem spots in your field of vision.
