Eye. Computer artwork of a section through a healthy human eyeball. Light passes through the cornea (pink,far right),the eye's main light- focusing structure. The iris (pink,behind the cornea) contracts or relaxes to allow the ideal amount of light through the pupil,the central hole of the iris. The light is finely focused by the lens (red,centre right),before hitting the retina (dark red,centre) that lines the inside of the eyeball. The light-sensitive cells in the retina convert the light into a nerve signal that passes along the optic nerve (green,lower left) to the brain for processing | |
