Prevalence

The prevalence of colour blindness varies significantly between men and women. This is due to the fact that the genes responsible for colour vision are located on the X chromosome. Men have only one X chromosome, while women have two. This means that men are more likely to inherit the genes for colour blindness, as they only need to inherit one copy of the gene from their mother. Women, on the other hand, need to inherit two copies of the gene, one from each parent, in order to be colour blind.

Genetic factors: The most common cause of colour blindness is genetic factors. Colour blindness is inherited in a recessive manner, which means that a person must inherit two copies of the gene for colour blindness, one from each parent, in order to be colour blind.
Eye damage: Colour blindness can also be caused by damage to the eye, such as from an injury or disease. This type of colour blindness is known as acquired colour blindness.
Certain medical conditions: Certain medical conditions, such as diabetes and macular degeneration, can also cause colour blindness.
Age: Colour blindness can also become more pronounced with age.
