To pass each test you must identify the correct number. Keep your arm with the phone extended in front of you, with each circle set at eye level.

Continue to the next Color Blind Test, Pass all tests without any problem and then you know that you are not color blind and there is no need to go to another test.

If you have any problems with the numbers just try again, it doesn't matter how much time it takes to type the answer. Some color blind test numbers are harder to see even for people who have exceptional eyesight.

If you still can't figure out the number or you always get the wrong answer when you type the color blind test result for each number, you might be color blind.
If that is the case, please go to a specialist so they can definitely confirm the color blindness.
