Test Your Sight

Instructions For Use

1. An Amsler grid (Print an Amsler grid or bring it up on your computer screen.)

2. A well-lit room

3. Some tape (to tape the chart at your location of choice)

4. A ruler or tape measure (to measure your distance from the chart)

5. And in an ideal world, an assistant


1. Print an Amsler grid or bring it up on your computer screen.

2. Choose a well-lit and bright room. In this room, pick a wall or door or location that is away from any window glare. Some people prefer to use the refrigerator door in the kitchen.

3. Affix the grid on this wall or door. If you are using your computer screen, then place your computer in this location. The center dot of the grid must be at your eye level. So decide whether you want to do the test sitting down or standing up before you tape the grid in position.

4. Place a mark (best done with tape) at the point which is 14 inches from the grid. Use your ruler or tape measure to be as precise as possible.

5. Stand or sit facing the grid at the 14-inch mark. Make sure you wear your normal reading glasses or contact lens.

6. Cover one eye with your palm (make sure no light can enter), and look at the dot in the center of the grid.

7. You should see all 4 corners of the grid, as well as the horizontal and vertical lines.

8. While looking at the dot, look for any distortion or blurriness of the grid pattern. This may appear as a blank, smudgy or wavy patch. If you notice any abnormality, try to note down its position. Either tell your assistance or mark it on the grid with pencil.

9. Repeat with your other eye covered
