Amsler Grid Test


The Amsler Grid is a tool applied by Optometrist and Ophthalmologist (eye doctors) for detecting vision problems resulting from damage to the macula (the central part of the retina) or the optic nerve.

If you suspect being at risk for macular degeneration or other eye diseases, you can use this chart at home to monitor your vision.

The chart below is an approximation of the printed chart used by Optometrist and Ophthalmologist. For more accurate detection of macular damage, you will need a complete eye exam.





1. If you need reading glasses, wear them while you use the Amsler grid. The grid should be at about the same distance from your eyes as reading other documents.

2. Test both eyes. First cover one eye, then focus on the dot in the center.
3. Do any of the lines look wavy, blurred or distorted? (All lines should be straight, all intersections should form right angles and all the squares should be the same size.)
4. Are there any missing areas or dark areas in the grid?
5. Are all corners and sides of the grid visible
6. Repeat the same steps testing another eye.

VERY IMPORTANT: Report any irregularity to your eye doctor immediately. Also mark areas of the chart that you’re not seeing properly and show the chart to him/her at eye exam.
