Their color discrimination is sufficiently impaired that it may cause difficulty at school or work when the task involves color, especially if time limits are imposed. Those identified as having a moderate color vision deficiency will consistently make mistakes on color vision tests. Except for those jobs requiring perfect color vision, most career choices will be open to people with the mildest color vision deficiencies. Their color vision deficiency is unlikely to cause difficulties, even on color related tasks. Individuals identified as having mild color vision deficiencies will make a few mistakes on color vision tests. A full, accurately calibrated test can distinguish between different levels of severity. You should try to find a shape for each of the two gray circles.Ĭolor vision deficiencies range from mild to severe. If you see more than one shape in a circle, choose the shape that has a color most different from gray as the correct answer. Try to find a colored shape in each of the two large gray circles. You might see a circle, a triangle, a square, or a diamond. Below each large circle is an answer row indicating the possible shapes that you might see formed by colored dots. Only an eye care specialist trained in testing for color blindness can provide a thorough evaluation. Accurate testing must be done with the actual printed Neitz test, which is precisely calibrated.
This online version of the test is meant only to provide an indication of whether or not someone might have a color vision deficiency, based on two example items from the Neitz test. It can be used with people of any age, including very young children. The test for red/green color blindness, below, is called the Neitz Test of Color Vision. It is a revolutionary new approach to testing for color blindness, created by an RPB grantee. In a classroom of 20 children, it is likely that at least one will have a problem discerning color. Our global community increasingly relies on color to communicate.
