    Inside the eye
Description:
Eyes are sensory organs that detect light and allow us to see things. This cross-section shows the structure of the human eye. Light is let into the eye by the coloured iris at the front. This light is then focused by the lens (the blue disc) onto the retina at the back of the eyeball (the yellow area). Whatever is seen is then transmitted to the brain via the optic nerve.
