There are several causes of a person experiencing color blindness, including:

Genetic factors. Most color blind people who experience it from birth are caused by genetic factors that bind to the X chromosome. A father of color blindness will not have children who suffer from color blindness unless their partner has a color blindness gene. This may be because women play a role in becoming a carrier that will inherit color blindness to children. People with color blindness due to genetic factors are also far more common in men than women, although sometimes this condition can pass through a generation. Girls are confirmed to have color blindness if both parents are carriers of the color blind gene.

Disease. There are a number of diseases that can cause color blindness, such as Parkinson's disease, Alzheimer's disease, glaucoma, blood cancer (leukemia), diabetes, chronic alcoholic addicts, macular degeneration, and sickle cell anemia.

Age. A person's ability to distinguish colors slowly decreases with age. This is a natural thing in the aging process and there is no need to worry too much.

Chemical material. A person can experience color blindness if exposed to toxic chemicals, for example at work, such as carbon disulfide and fertilizer.

Side effects of certain medications. Some treatments have the potential to cause color blindness, such as digoxin, phenytoin, chloroquine, and sildenafil. If the disorder is caused by treatment, usually the view will return to normal after stopping taking the drug.
