Do you know what it is to live like a color blind? About the complexities of color blindness?
Can you imagine how the world would be like if it were all blue? Imagine your life where you need a label to distinguish between tomato ketchup and chocolate syrup? What if ripe and unripe bananas look similar to you? Is it possible to achieve dreams if you were color blind?
“Color Vision Deficiency isn’t the end of the world. It’s just a different view of it.” – Karen Rae Levine
Here are facts that will help you know what it is like to live with color blindness:
1. 99% of all colorblind people are not really color blind. They just have color vision deficiency that doesn’t let them distinguish between red and green or blue and yellow and some other color shades. A complete absence of colors is very rare. The term color blindness is misleading.
2. Dogs, cats, and rabbits see mostly gray.
3. Bees and butterflies have superior vision and can see colors humans can’t even see.
4. It is very rare for a color-blind person to just see black and gray.
5. Among all color blind people, 99% are suffering from red-green color blindness. The next most common is blue-yellow color blindness.
6. 8% of men (1 in 12 men) and 0.5% of women (1 in 200 women) with Northern European ancestry have a common form of red-green color deficiency.
7. Color blindness is highly prevalent in men than women as the genes responsible for the most common forms of color blindness are on the X sex chromosome. Color blindness is passed from mother to son on the 23rd chromosome.
8. Color vision deficiency can also be caused by eye diseases, aging, or retina damage.
9. The most frustrating thing for color blindness is not the real limitation but the question – “what color is this (pointing at something)?”
10. If a father is red-green color blind, he cannot pass it on to his sons. But, a mother with red-green color blindness, can pass the condition to all her sons.
11. Blue-yellow color blindness is a dominant, not sex-linked trait, which means both men and women are equally affected.
12. One in every 12 males in the US may be affected by color blindness while for females, there is only less than one in 200.
13. All newborn babies are color blind. Within 7 days of birth, they start to see colors and tend to develop a functional color vision by the time they turn 6 years old.
14. There are three main types of color vision deficiency: protan, deutan, and Tritan defects based on the different kinds of cones found in the retina that respond to blue, green, and red light.
15. Better color vision deficiency terms would be red-blindness for protanopia, red-weakness for protanomaly, green-blindness for deuteranopia, green-weakness for deuteranomaly, blue-blindness for tritanopia, and blue-weakness for tritanomaly.
16. Colorblind people can distinguish between 15 shades of khaki. These shades are invisible to normal people because they look identical.
17. Till date, there is no known treatment or preventive measure for color blindness because it is an inherited disease.
18. Colored lenses or glasses can help improve color discrimination in your problem areas but cannot give you back normal color vision.
19. EnChroma – a type of sunglass that was invented in 2012 that actually improves color vision in people with red-green color deficiency.
20. Also, there are some iPhone and iPad apps available that help people with color blindness distinguish colors. The user can snap an image of any object and tap it anywhere on the image to see the color of that area.
21. A fatal railway accident in Sweden in 1875 was believed to be caused by a color-blind rail operator who failed to properly read a signal. This incident led to the development of color vision test for railroad workers.
