There is basically no cure for color blindness, but you can wear eyes.
Color blindness is a visual defect. Because of the abnormal or incomplete photosensitive pigment in cone cells of retina, it lacks the ability to distinguish one or several colors. According to the clinical manifestations, it can be divided into color blindness and partial color blindness. You can't tell colors at all, and the feeling of seeing only black, white and gray is called color blindness or monochromatic vision. Often accompanied by a high degree of photophobia, frequent blinking, obvious decline in vision, central scotoma, sun blindness and so on. Losing the ability to distinguish a certain color is called partial color blindness. Among them, those who can't distinguish red are called red blindness or first color blindness, the red part of the spectrum is shortened, green is regarded as yellow, and purple is regarded as blue; Those who can't distinguish green are called green blindness or second color blindness, and green is regarded as gray or dark black in spectrum; Those who can't distinguish blue are called blue blindness or third color blindness, and can only distinguish red and green in the whole spectrum. Sometimes people who are blind in red and green can show amazing color discrimination, which is obtained from their life experiences. They can distinguish red from green according to the difference of saturation and brightness, but when testing color mixing, the essence of color blindness is revealed. Most of them are congenital, and the order of frequency is green blindness, red blindness, blue blindness and color blindness. In the 20th century, Wilson proposed that color blindness was transmitted through X-linked inheritance, which was inherited by women, with boys dominating and girls mostly asymptomatic. Only when women are a combination of recessive color blindness and color blindness men will women born show color blindness. Therefore, the incidence of male is about 5% and that of female is about 0.8%. There is no special treatment for congenital color blindness. Acquired color blindness is mostly caused by optic nerve diseases and retinal and choroidal diseases. The former is mainly red-green color blindness, while the latter is common in blue blindness. Different treatments can be given according to the cause. . . . . .
