Colour blindness is basically a malfunctioning of the retina of the eye, which is responsible for the conversion of light energy into electrical energy, which is thereafter transferred to the brain in the form of signals. The conversion is carried out by two types of photoreceptor cells within the retina: cones, and rods. Disturbances or disorders in colour perception will occur when the amount of pigment present per cone is reduced, or absent.
At times, it is possible that a person may acquire colour blindness due to some rare disorder or disease, but more often than not, colour blindness is an inherited condition, which is passed on from a parent to a child.
The gene for colour blindness is carried in the X chromosomes, and it can occur more often in a male than in a female, although it is a fact that the chances of a female being a carrier of colour blindness are more than a male being a carrier.
