When a person is colorblind, what does this mean? Do they see it in black and white? Well, not typically (but that’s possible, too!). Research shows that 1 in 5 men are colorblind, while 1 in 200 women are colorblind. But what is the difference between this and normal color vision?
Color blindness, also known as color deficiency (or daltonism), occurs when a person is unable to distinguish between certain colors (most commonly red-green), in contrast to people who have a full-color vision. The cones in your eyes contain pigments that allow you to see all colors. Color vision deficiencies can occur when pigments are missing or displaced.
