Test Your Vision
The Amsler grid was originally developed by Marc Amsler to allow patients to test their own central vision for early signs of macular degeneration, so it may be treated sooner. This test consists of a grid of vertical and horizontal lines.
Look through your reading glasses or bifocals.Cover the left eye. While looking at the centre dot from a distance of 12 inches or so, answer the following questions: Can you see all four corners of the grid? Are any of the lines blurry, wavy, distorted, bent, grey, or missing?Repeat the previous step after covering the right eye.
If you note any changes in how you see the grid, call your eye doctor for evaluation.
We recommend you keep the grid where you can use it 2-3 times a week.
