A BRIEF ANALYSIS OF COLORBLINDNESS
Synonyms for colorblindness: achromatic vision, achromatopsia, color vision deficiency, daltonism, dichromatic vision, deuteranopia, monochromacy History of colorblindness: John Dalton (Note the word “daltonism”) described his own colorblindness in He confused red with green and pink with blue. John Dalton researched colorblindness and realized that it was hereditary, because his brother was affected with the condition as well. Origin of the name (time): How is it inherited? Colorblindness is passed down on the 23rd chromosome . Only females can be carriers because the colorblindness gene is located on the X chromosome. Because girls have two X chromosomes, they can have the gene and not be affected. If males have it, then they will be affected because they have only 1 X chromosome. John Dalton Mary Claire

How common is colorblindness?
About 1 in 10 men are colorblind - it isn’t uncommon. Only 1 in 200 women are colorblind If the mother of a child is a carrier of colorblindness and the father is not, then there is a 1 in 2 chance that either(if it’s a boy) he will be colorblind, or (if it’s a girl) she will be a carrier of the disease.

What is colorblindness?
You can see colors because of the three cone cells in your eyes. They allow you to see red, green or blue light. Colorblindness occurs when either you don’t have one of these cones or they don’t work properly. The disease is usually inherited, but it could also be caused by aging, an injury or an illness. Symptoms Some people can see some colors but have trouble distinguishing others (for example, they can see red and blue but can’t recognize green and yellow) In some rare cases, they see only gray, black and white Effects If you play sports, you may have a hard time distinguishing jersey colors For example, if you had a pack of 35 colored pencils, the average red-green colorblind person would only see about 12 shades Mary Claire

How to treat colorblindness
Is gene therapy a possibility? Right now it’s a no for humans until it’s made safer, but scientists have cured a monkey of colorblindness. How long is a colorblind person’s life expectancy? A colorblind person’s life is the exact same as a normal person’s life, luckily. How do doctors test a person for colorblindness? To the bottom right is a common type of test that doctors use. Is there a cure? No. But colorblindness isn’t life-threatening, and colorblind people lead a fairly normal life. Yaneli

What if it was you? What if you were colorblind? Maybe if you were in school, and you had to color in certain things in a picture certain colors, you would have to tell the teacher you couldn’t do it. You probably wouldn’t know what you were missing out on color-wise. Your family would probably carry on as usual. Max

Peter milton’s story Peter Milton was a painter. He was showing a painting when someone told him how warm and pinky the landscapes looked like, which wasn’t the effect he was going for. He went to have his eyes tested and discovered that he had deuteranopia (or red-green colorblindness). For Peter, green looked yellow-gray and orange looked brown. Instead of giving up artistry, he decided to start painting in black and white. One of Peter Milton’s paintings Max
