SPOTTING THE EARLY SYMPTOMS IN CHILDREN:Ĭhildren who suffer from colour blindness see colours differently as compared to normal children. Parkinson's, cataracts, Leber's hereditary optic neuropathy, Kallman's syndrome, shaken baby syndrome, accidents and overexposure to ultraviolet light are other prevalent causes of colour blindness. Blue-colour blindness happens in only 5 per cent of cases and occurs equally in both girls and boys.Ĭolour blindness is more common in men than in women, though women are the carriers of the gene. It occurs in about 8 per cent of the boys and is slightly less in case of girls with a per cent of 0.4. Red-green colour blindness is the most common type of this condition in children. In the case of a child who is colour blind, only two out of the three types of cone cells work normally. There are usually three types of cone cells and each type is responsible for picking up a different colour such as red, green, and blue. Rod cells see things at night but do not pick up colours while cone cells pick up brighter light and are able to differentiate between colours. According to a leading health website, there are two types of light-sensitive cells called rod and cones in the retina of the eye. Let us look at the main cause of colour blindness in children. Other causes of colour blindness can range from macular degeneration, aging, injury to the eye, diabetic retinopathy, glaucoma or cataract, etc. However, colour blindness in children is not always inherited.
