Eyes

The eyes are organs. They detect light, regulate the light through a diaphragm, focuses it through adjustable lenses and converts them into electo-chemical impulses in our neurons by photoreceptor cells called rods and cones. The image is converted into a set of electrical signals that are transmitted to the brain via neural pathways that connect the eye to the optic nerve and visual cortex of the brain. In short, eyes are very complex optical systems that convert light to distinguish objects and movement around us.
