Test the vision in each eye every day. Early detection of a vision problem increases the chance of saving eyesight through timely treatment. The Amsler Grid is a simple test of vision quality that detects even minor changes when they first occur. This easy test only takes a moment for each eye. If you notice any changes in the appearance of the grid such as distortion, blurring, discoloration, dark or missing areas of the grid, or any other changes, call and visit your retinologist immediately! Do not wait to see if the changes will clear up with no intervention.
To Test your vision:
1. Position the Amsler Grid at a comfortable reading distance. Wear your reading glasses. Face the image squarely. The pattern should be in focus.
2. Cover one eye with your hand. Look directly at the dot in the center of the grid. Note whether the lines are straight and the corners intact. Make certain you only look at the center.
3. If any of the lines appear distorted, blurred, discolored, or totally absent, call your retinologist right away.
4. Repeat the test for the other eye.
