Understanding Color Blindness
What You Need To Know About Color Blindness
When someone mentions color blindness, what is the first thing that pops into your mind? Maybe it’s imagining the black and white vision that a dog has, or maybe the pictures of the colored dots that make up letters or numbers that the doctor always shows you when you’re getting your yearly check-up. Whatever pops in to your mind, you might be wondering how different your vision would be if you had color vision deficiency (color blindness).
First off, there is one thing to be cleared up: people that are affected by color vision deficiency are rarely ever limited to seeing just black and white. Usually, they just have trouble with detecting the difference between reds, greens, and blues, or differentiating between the shades of any of those colors. So, when the doctors show you those diagrams of the numbers made out of different colored dots, they are testing to make sure that you can detect the difference in the colors and that you are indeed able to tell the difference between the green dots making up the number and the red dots surrounding it.
There are cones in your eyes that detect different color lights, red, green, or blue, the primary light colors, and if these cones are damaged your eyes lose the ability to detect one or more of these colors, and the secondary colors they make. This damage could be a birth defect or by physical damage to the eye. Either way, the cones in the eye are damaged and the eye can no longer differentiate between colors. For example someone that is color blind can have a lot of trouble telling the difference betweens yellow and blue and red and green.
