At Home Vision Test
Before scheduling your virtual visit please check your vision.
Home vision testing is not a substitute for a complete medical eye examination by an ophthalmologist. Testing your vision at home will not be as accurate as what your ophthalmologist can do. But home eye testing could help you discover a problem that requires professional attention.
Testing distance vision:

Hang on wall and step back 10 feet

or if you do not have access to a printer you can check now on your computer.
DISTANCE VISION Test if unable to perform above with printer
In order for the test to be performed correctly, allow the following distance between subject and screen:
- • 7 feet from a 20” screen;
- • 5 feet from a 17” screen;
- • 3 feet from a 12” screen;
- • 2 feet from a 13” screen.
Cover left eye with your left hand, ensure to avoid applying pressure to the eyelid. Read the letters on the screen beginning at the top. Once completed, repeat with the right eye.
If you were able to read as easily with both the left and right eye, chances are you have a strong central visual acuity.

NEAR VISION TEST:
Test your near vision here. To perform the test, remove your glasses and move back 12” to 16” from the screen. Cover left eye with your left hand and try to read the text to the end and repeat with the right eye.
Testing Amsler vision:
Who should use it?
Any patient may use this grid. However, it is especially important that Diabetic and Macular Degeneration patients use it, as they have an increased risk for developing changes in the macula that will affect their central vision.
How do I use it?
If you wear glasses or reading glasses, make sure you are wearing them. If you wear bifocal glasses, be sure you are looking through the reading part of the lenses.
Place the grid approximately 12 inches from you at eye level.
Cover one eye, and concentrate on the central dot in the center of the grid.
COLOR VISION TEST
The Ishihara test is used to detect colour blindness, an anomaly responsible for colour vision deficiencies. To perform the test, sit about three feet away from your computer screen. Look at each of the circles below, what do you see?
If you are unable to see a 7, 13 and 16 in the upper row of circles and an 8, 12 and 9 in the lower row, you definitely have a vision problem. A comprehensive exam, performed by an optometrist is suggested.
