Color Blindness- Sam Poulin

Color blindness is a genetically inherited deficiency of photopigments, or color cones in your eyes that is shown in more men than women. These cones allow us to see about 100 million shades of color. However for 2.7 million people in the America, a certain group of cones don't work properly or at all, which means they can only see a handful of colors. There are three types of colorblindness, red-green, blue-yellow, and monochromatic, in other words, they can only see black and white. but for the sake of this blog, I'm going to be talking about red-green colorblindness. Red-green colorblindness is inherited on the "X" chromosome on the 23rd pair. Being red-green colorblind means that you often can't tell the difference between red and green. Men are more likely to be colorblind because they either have it or they don't, they can't be a carrier. Women are less likely the be colorblind because they have two "X" chromosomes, so they can either be colorblind, be a carrier, or not be colorblind. One thing I learned while researching this was that a company called EnChroma has created a pair of glasses to allow red-green colorblind people see normal color. This blog could help you in real life because if you were red-green colorblind, you could understand why you're colorblind and how you could be able to see normal color. The picture is a red-green colorblind test, if you don't see the number, you could be colorblind.
