Color weakness may be inherited from the father and may also be caused by the mother.
Color weakness indicates that the body’s ability to discriminate colors is reduced, which is mainly related to congenital genetic factors and acquired factors. Among them, congenital genetic factors are mostly X-chromosome chain recessive inheritance, and there is a family aggregation of the onset of characteristics, so color weakness may be inherited from the father, may also be inherited from the mother. If both parents are color deficiency, most of the children are color deficiency patients.
If the father is normal and the mother is amblyopic, the son will be amblyopic and the daughter will be a carrier of the abnormal gene. If the father is color-frail and the mother is completely normal, the son will be normal and the daughter may be a carrier. In addition to genetic factors, other factors such as optic nerve atrophy, retinal detachment, and aging of the eyes may cause color weakness and should be identified.
It is suggested that people with clear color weakness should cooperate with doctors according to their own conditions, pay attention to eye rest and avoid eye fatigue caused by prolonged use of the eyes.
