Have you ever taken the test to see if you are colorblind before? Chances are you have, and you already know if you are colorblind or not. If you are colorblind odds are that you are male since most genes related to colorblindness are on the X chromosome. Most colorblind people are that way because of genetics, but it can also be caused by eye, brain, or optic nerve damage. Exposure to certain chemicals can also cause colorblindness.

    I believe I am deutetanopia color blind but I have am interesting experience. I bought a pair of dark orange prescription sun glasses and took the color test at my ornithologist’s clinic and with them on I could read the circles that I couldn’t without them on, but with then on I couldn’t read others. maybe some kind of solution there?
