Who is the father of color blindness?

John Dalton, a chemist, physicist, and meteorologist was best known for introducing the atomic theory into chemistry. He was also the first scientist to study color blindness, publishing a paper on the topic, entitled, Extraordinary Facts Relating to the Vision of Colours with Observations.

Color blindness affects an individual's ability to see and distinguish differences in color. It largely affects men (more on that below). Ophthalmologists determine that as much as 10% of the male population has diminished color vision, but women can have it as well (only about 1 in 200 women).

Can girls be color blind?

Yes, but the chances are slim! Color blindness occurs in only about 1 in 200 women (compared to 1 in 12 men)*. As a result, approximately 95% of people with color blindness are men.
