Color blindness common in males.

Inherited color deficiencies are much more common in males than in females. It can affect about one in 20 men versus one in 200 women. In red green color blindness this means difficulty distinguishing between shades of red green and yellow. The most common cause of color blindness is an inherited problem in the development of one or more of the three sets of the eyes cone cells which sense color.

The most common color deficiency is red green with blue yellow deficiency being much less common. The genes that can give you red green color blindness are passed down on the x chromosome. It is much more common for men to inherit color blindness. Males have only one x chromosome whereas females have two x chromosomes.

You can inherit a mild moderate or severe degree of the disorder. Since it s passed down on the x chromosome red green color blindness is more common in men. In males only one defective x chromosome is enough to cause colour blindness. There is no treatment for color blindness when it is inherited.

It is rare to have no color vision at all.
