Color blindness is a condition that causes sufferers to be unable to distinguish certain colors normally. This condition is caused by damage to the cells that function to detect color pigments. As a result, eyes no can detect certain colors, even all colors.
Interestingly, although this visual impairment is called color blindness, it does not mean that the sufferer can only see black and white colors. However, there are also people with color blindness who no can see red or see blue as green. Hence, color blindness is divided into three types.
What are the types of color blindness? Reporting from Health Line, here are three types of color blindness.
