The Amsler Grid

The Amsler Grid is a grid of horizontal and vertical lines used to pick up subtle changes in vision. It is most often used as a tool to detect visual disturbances caused by changes in the retina, particularly the macula.

You can test your vision at home using the Amsler Grid by following these instructions:

  1. If you wear glasses or contact lenses, continue wearing them for the test.
  2. Position yourself approximately 14 inches from the grid.
  3. Cover one eye with your hand and focus on the central dot with your uncovered eye.
  4. Repeat the test with your other eye.

If you see wavy, broken or distorted lines when focusing on the central dot, you may be displaying symptoms of macular degeneration. Contact the Taustine Eye Center to make an appointment with Dr. Kritchman, our macular degeneration specialist.
