What is color blindness? How do color blind people see the world? And how many people in the world are affected by color blindness?

What's color blindness?

Color blindness, also known as color vision deficiency, is not a disease but the decreased ability to see color or differences in color. Approximately every 1 in 12 men and 1 in 200 women are affected by it. So, there is a high probability that someone who you know a neighbor or a co-student is color blind.

For a person with normal vision, it is hard to imagine what it is like to be color-blind and how people like this see the world. Which color do they see? Do they see any at all? And so on.

That is why we, at Bright Side, prepared a visual comparison of all colorblindness types and put them together for your better understanding.

There are four different types of color blindness. Each of them provides deficiency in different color shades.

SUMMARY

The color blindness as a vision deficiency was discovered by English chemist John Dalton after he realized that he was color blind himself. In 1798, he published the first scientific paper related to this subject which was called “Extraordinary facts relating to the vision of colors.” Due to his unmeasurable input into the research of color blindness, the general condition has been called after him and known as Daltonism. Though, in English, this term is now used only for deuteranopia.
