The Truth About Color Blindness Is More Than Black And White. Here’s The Breakdown.

There are four kinds of color blindness.

Color blindness is not something that's plain to see and a new video from Bright Side takes a look at the condition.

Celebrities such as former President Bill Clinton, Keanu Reeves, Mark Zuckerberg, and Prince William reportedly deal with some form of color vision deficiency. It's not a disease but rather a decreased ability to see color or differences in color, and collectively, the four types impact 1 in 12 men and 1 in 200 women.

The most common form, which impacts 4.63 percent of men, is called deuteranopia. It's basically when colors lose some of their brightness, especially greens and reds.


A less widespread form of color blindness is protanopia, with only around 1 percent of men experiencing it. Again, its central to greens and reds, which appear somewhat faded.

An even more rare form of color blindness, which affects both men and women equally, is tritanopia, and it colors their world in greenish and pink tones.

Finally, only 0.00003 percent of the whole world's population is affected by total color blindness, which basically wipes out all color.

All forms of color blindness impact things in their day to day, such as like traffic lights, making it more difficult for people with the color vision deficiency to drive.

So how does it happen?

According to the National Eye Institute, inherited color blindness is caused by abnormal photopigments. "In humans, several genes are needed for the body to make photopigments, and defects in these genes can lead to color blindness."

The inherited color blindness genes, which is the most common way people become color-blind, are on the X chromosome, making men more likely to be color-blind.

But color blindness isn't always inherited. It can also be caused by "physical and chemical damage to the eye, the optic nerve, or parts of the brain that process color information." Aging can also be associated with a decline in color vision because of cataracts, or a clouding and yellowing of the eye's lens.

Even with all the explanations about colorblindness, for some, it could be difficult to grasp what it's really like.
