Light striking the retina initiates a cascade of chemical and electrical events that ultimately trigger nerve impulses. These are sent to various visual centres of the brain through the fibres of the optic nerve. For vision, these are of two types of photoreceptor cells: the rods and cones. Rods function mainly in dim light and provide black-and-white vision while cones support the perception of colour. The  retina  has ten distinct layers In adult humans. The entire retina contains about 7 million cones and 75 to 150 million rods. An image is produced by the patterned excitation of the cones and rods in the retina. The cones respond to bright light and mediate high-resolution colour visio...
