Color blindness, defined as a disorder of differentiating different colors, is most common in men. The cause of this disease is the lack or absence of pigments in the retina of the eye.
The most common type of color blindness is the inability to distinguish between green and red. However, not only color blinds, but also many other people cannot distinguish these colors in the dark. Some color blinds cannot distinguish blue and green. In rare cases, people cannot discern any of the colors. This case is called “monochromotism” and these people see the world in black and white.
