See in color

The retina is filled with a layer of tiny cells called rods and cones. These cells contain coloured substances that react when light falls on them, triggering a nerve impulse.

Rods are slim cells that are responsible for us seeing in block and white. They work even if the light is very poor, seeing everything in shades of grey. Cone cells give us colour vision. They contain different light- sensitive substances that respond to either red, yellow-green or blue-violet light. Together with the grey images produced form the road, cone cells give you the coloured picture that you see. Cones can only work in bright light which is why colours are so hard to see in dim light. You have 125 million rod cells and 7 million cone cells in each eye.
