Colour blindness is a vision-related disorder that causes a person to face difficulty in identifying one or more colours. Colour blindness can occur in any person from birth or due to other reasons. This problem can also arise later in life. Eye experts believe that colour blindness occurs when the light-sensitive cells in the retina fail to respond appropriately to different wavelengths of light. With the help of these cells, a person is able to see any colour. Usually, genes inherited from your parents causing defective photopigment. But sometimes colour blindness is not due to genes. They can have other factors are involved. For example, physical and chemical damage to the eyes, damage to the optic nerve, ageing, cataracts, etc. In addition, sometimes it could be damage to the parts of the brain that process colour information that can cause a person to not be able to recognize the colours.
