Color blind test

Are you having trouble seeing colors as clearly as you should? Do you ever find it strange when someone tells you something has different shades, but to you, they all look the same? Color blindness could be the cause.

Some people are color blind without even knowing it. Their perception is that green is a color associated with tree leaves, so they believe that the color they see is green.
In most cases, you won't see things in shades of gray because of this vision problem. That’s rare. Most people who are color blind have trouble telling some colors apart. There is a possibility that they cannot distinguish between red and green or blue and yellow.

Several ways can be used to check for the condition by eye professionals. There are a variety of tests that use colored tablets or diagrams.

Who conducts the tests?


You should see an ophthalmologist if you notice any serious changes in your vision. That's a doctor who specializes in vision and eye care. Get your symptoms checked out because they could be a warning sign of something more serious. If you are having trouble seeing colors, you should also talk to your regular doctor.

School nurses sometimes test students for color problems.

Genetics plays a role in color blindness. Test yourself if you have relatives with the disease.


What are the different types of tests?


types of color blind test



Ishihara color test . The purpose of this test is to check for red-green color blindness. You will be asked to look at a series of circles with dots of different sizes and colors. There are some dots that form shapes or numbers. You may not be able to see those shapes if you have trouble seeing red and green.


Cambridge color test.  It's similar to the Ishihara test, except that you look at a computer screen instead. Find a "C" shape with a different color than the background. The pop-up appears at random. Press one of the four keys when you see it.


Anomaloscope . A circle appears when you look through the eyepiece. In the top half of the circle, there is a yellow light. In the bottom half, there are red and green lights. As you turn knobs, you must ensure that both halves are the same color and brightness. This test is used to determine if a patient has trouble seeing red and green.


Farnsworth-Munsell 100 hue test . Pegs or blocks of the same color in differing shades are used for this game. It's your job to line them up in a certain order. In this test, you will see if you are able to detect slight color differences in the image. In some companies, it is used to train workers to see colors correctly.


Farnsworth lantern test . U.S. military recruits use this test to determine whether they have mild or severe color blindness. If your condition is mild, you can serve in the military.


Some things can be tricky if you are color blind, but it is not a serious condition. You can still drive, work, and live normally. However, you may need to find other ways to accomplish some tasks. It is possible to wear special contact lenses if you suffer from red-and-green color blindness. There are also apps that can help people with colors.
