One of the main causes of color blindness is genetics, so if someone in your family has had this disease, you need to take color blindness tests to confirm your condition before getting married.

Color blindness, also known as color vision disorder or color vision disorder, is an eye disease that makes people able to see things clearly but cannot distinguish certain colors. The disease does not affect the ability to live of the person with the disease, so people with the disease can still live and reproduce normally, so the disease gene has the risk of spreading in the community.
