While the name might seem to imply that a person who is color blind sees only in black and white, this is not completely accurate. While this can happen, it is extremely rare. More common are the people who are affected by color blindness typically see color with less of a range.
National Color Blind Awareness Day is here to bring attention to this special vision trait and help the world to understand just a bit more about it!
History of National Color Blind Awareness Day
National Color Blind Awareness Day takes place on the anniversary of the birth of scientist John Dalton in 1766. Dalton was the first person to discover that the human eye can see colors in different ways. In fact, the motivation behind it was the fact that Dalton and his brother both saw colors differently than most other people.
Dalton’s reasoning was incorrect, since thought it was because of a kind of blue liquid in their eyes. And his name for this was “Daltonism”. In a magnanimous effort to clear up the question, Dalton even left his eyes to science after he died. What he didn’t realize is that the condition must be hereditary as it affected both him and his brother, which would only be confirmed more than 150 years later when DNA proved that color blindness was a genetically inherited trait.
The first National Color Blind Awareness Day was celebrated in 2015 and founded by Colour Blind Awareness, which is a non-profit interest group that was started in 2010. The group is dedicated to raising awareness about the needs of color blind people in communities.
Since its founding, National Color Blind Awareness Day has continued to grow each year, with millions of people all over the world engaging on social media and in other ways.
