Life is not so straightforward for people with color blindness. Color blindness is caused by damage or genetic mutations to the cells responsible for color vision at the back of the eye.
– Color vision is the result of a complex interplay between photoreceptors, the optic nerve, and the brain.
– Color blindness primarily affects men because the genes for the red and green photoreceptors are found on the X chromosome.
