Online Vision Test
An early diagnosis means early treatment, which can save your vision.
The Amsler grid and Near Vision Charts are tools that our eye doctors use to detect vision problems resulting from damage to the macula (the central part of the retina) or the optic nerve. The damage may be caused by macular degeneration, glaucoma, or other eye diseases.
If you are at risk for macular degeneration or other eye diseases, you can test your vision at home by downloading the Amsler Grid and Near Vision Chart below. However, the online vision test does not replace regular eye exams. There are some signs that only a trained eye care practitioner will find.
How to Test Yourself with the Amsler Grid
1. Testing must be done wearing your usual reading prescription (reading glasses or bifocals) if you use a reading prescription.
2. Testing is done one eye at a time, holding the Amsler chart at the distance from your face where the lines appear most clear. (Approximately 14 inches is a good starting distance. Move the chart closer toward you and further from you until the lines are clearest.)
3. Cover your left eye. Concentrate on the dot in the center of the chart, being aware of the vertical and horizontal lines around the dot, even though you are not moving your gaze away from the dot. While watching the dot, you are judging whether the vertical and horizontal lines are straight and even, or whether they appear to be curved, distorted, or missing.
4. Cover your right eye and observe the grid in the same manner with your left eye as you did with your right eye.
5. If the lines look irregular, blurred, wavy, missing, or discolored, promptly contact our office at (215) 335-3088.
How to Test Yourself with the Near Vision Chart
1. Print the Near Vision Chart.
2. Do not take this test if you are tired.
3. Do not study the chart before the test.
4. Choose a well-lighted room away from any window glare. Wear the glasses or contact lenses you normally use for reading.
5. Hold the Near Vision Chart about 14 inches away from your eyes.
6. Testing is done one eye at a time.
7. Cover your left eye and find the smallest line numbers/ letters that your right eye can read. Mark that line with an "R".
8. Cover your right eye and find the smallest line of number/letters that your left eye can read. Mark that line with an "L".
9. Repeat the test weekly.
10. If either eye is not able to read the line previously read and marked for that eye, then contact our office at (215) 335-3088.
Remember, this test does not replace regular eye exams.
