If you believe that you have visual impairment, this picture can give you an idea. All you need to do is determine how far away you are from the monitor, depending on the size of your monitor and the screen resolution. Then try to read the numbers from the top row to the bottom row by closing one eye. If you have difficulty reading, you should immediately consult an ophthalmologist.
Your viewing distance according to the screen resolution
Screen size resolution 640x480 800x600
14 inch 5.5 m 4.0 m
15 inch 6.0 m 4.5 m
17 inch 7.0 m 5.5 m
This measurement is not a substitute for doctor control.
If you cannot read the numbers in the figures below, you may be color blind.
The human eye is able to perceive and distinguish colors with the iris layer in the eye. It is possible to see some colors or all colors in gray in case of a problem in color perception in the iris layer. In this case, if you cannot distinguish the colors that represent different numbers from the other colors in the above tests, you are likely to be color blind.
Although the Amsler Grid Test is not the equivalent of a routine eye examination, it is a scheme that allows you to identify early signs of age-related macular degeneration (yellow spot disease) by performing it yourself. We recommend everyone over the age of 40 to take this test.
