Eye Health - Color Blindness in Children
Did you know that color blindness affects boys at a much higher frequency than girls?
This is because the genetic marker responsible for color blindness is found in the X chromosome. Since girls have two, the second chromosome almost always compensates for the other - because boys only have one X chromosome it is impossible for them to compensate. This is why it is much more commonplace for boys to be color blind. But this only impacts people born color blind. Developed color blindness can affect both men and women equally.
Did you know that people with developed color blindness can still dream in color?
Visual dreaming is possible for developed color blindness because the individual can recall the colors they no longer see. It is said that this can become harder to do as time goes on.
Genetic Color Blindness
Color blindness is most commonly inherited genetically from one of the parents and results in a child being color blind from birth.
This defect in the X chromosome affects how any number of the retinal cones within the eye respond to light. An inability to discern green from red is the most common form of color blindness. Sometimes people experienced Blue/Yellow color blindness.
In very rare cases complete color blindness can occur.
Developed Color Blindness
People can become color blind later in life when the optic nerve or retina are damaged by disease or chronic illness such as glaucoma, diabetes, or macular degeneration (AMD). Leukemia, multiple sclerosis, and sickle cell anemia can also lead to developed color blindness in children.
Identifying Color Blindness
Color Blindness can usually be self identified and confirmed with a simple color test that can be administered anywhere. If you would like to test yourself or someone in your family for Color Blindness, Enchroma provides a test for all three types of color blindness on their website - Available here.
