Is color blindness caused by retinal damage?

Generally not. We know that color blindness is caused by genetic and congenital factors, making it difficult for affected individuals to distinguish color differences between objects of varying wavelengths. This is a natural condition, thus making treatment challenging. Overall, prevention and rehabilitation will be the priorities. Treatment may include massaging corresponding acupoints, acupuncture, or wearing corrective glasses, which can yield fairly good results. Additionally, this group of people should also pay attention to eye hygiene and develop healthy eye-care habits.
