Color Blindness Is Something You Should Know About
Color blindness is
a condition that's often misunderstood by a lot of people in the world. Contrary to popular belief, a person who is colorblind can still see colors; they just don't see them in the same strength or frequency that a normal person sees them.
The name itself is actually pretty misleading; the official name for color blindness is color vision deficiency, which puts a finer point on the condition that these people are dealing with. If a person is extremely color blind, that is, on the lower end of color receptiveness, they will usually only be able to distinguish about 20 distinct hues in their visual field. This is less than one fifth of what a normal person will be able to see, since most people can actively tell the difference between over 100 individual hues.
Color Blindness also affects men much more often than it affects women, mostly because the Color Blindness Genetics that determines this or the ability to distinguish colors, as a whole is located in the X chromosome.
It's currently estimated that around 8 percent of men in the world experience some form of color vision deficiency. As it turns out, with this many people running around the planet who are color blind, there are some questions that you should never ask a friend who is colorblind. These have been determined from a survey of what questions annoy color blind people the most, so out of common courtesy, just try to avoid asking these questions of any color blind friends whenever possible.
The first question is “What color is this?” This has the tendency to make color blind people feel vaguely uncomfortable because they know that the color that they see is going to be different to what you're seeing.
They don't see a whole spectrum of different colors that you're unable to process, they simply see fewer colors because most hues tend to blend together for them. In the end, any answer they give isn't going to help you figure out how they see things any better, so it's better to just not ask.
The next question is “Can you only see gray?” Color blindness is vastly different from monochromacy, which is when you can only see shades of gray. Very few people are afflicted with this condition, and it's very unlikely that your colorblind friend has it.
As mentioned, they can actually still see colors, but their world may be populated with more reds and fewer Green Color Blindness for example, because their eyes take the deficiency in their ability to process green and replace it with an overabundance of red.
The third question is “Can you drive?” On the surface this question just sounds silly, because even though they can't process colors as well, colorblind people can still see everything else very clearly.
When you think about stoplights, it makes more sense, even though stoplights are designed to make it easier. For example, red is always on top and green is always on the bottom. I hope this information about what color blindness is was helpful.
