Color vision disorders
A color perception disorder is called daltonism . In total, 9% of men and 0.4% of women suffer from color blindness in the population. According to severity, they are divided into:
- complete color blindness: a person perceives only shades of gray;
- partial color blindness: impaired perception of only some of the colors (partial or complete).
In the population, the red and green color disorder is gonosomally recessively inherited (the responsible gene is located on the X chromosome ), therefore they are more common than the blue color vision disorder.
