Amsler Grid

The Amsler grid is a tool that eye doctors use to detect vision problems resulting from damage to the macula (the central part of the retina) or the optic nerve.

How to Test Yourself

Cover one eye, then focus on the dot in the centre.
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.)
Are there any missing areas or dark areas in the grid?
Can you see all corners and sides of the grid?
Don’t forget to test both eyes.

VERY IMPORTANT: Report any irregularity to your eye doctor immediately.

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