Explanation: Colour blindness or colour vision deficiency is the inability or decreased ability to see coluor, or perceive colour differences, under normal lighting conditions. The most usual cause is a fault in the development of one or more sets of retinal cones that perceive colour in light and transmit that information to the optic nerve. This type of colour blindness is usually a sex-linked condition. |
