This test can be taken with or without glasses.
To take this test correctly, it is necessary to place yourself at a distance from the screen of approximately:
- 2.20m for a 20" screen,
- 1.50m for a 17" screen,
- 1m for a 15" screen,
- 75cm for a 14" screen.
Cover one eye with your hand, without pressing on the lid, and read the test below, letter by letter.
Cover the other eye and begin the test again.
If you have read the test as successfully with the right eye as with the left eye, you probably have good central acuity
. If you do not manage to read all the letters, either with one eye or with two, an eyesight check by an eye care specialist would appear necessary.
