Eye anatomy,computer artwork. At the front of the eye is the cornea (light brown),a transparent coating. Behind this is the lens (blue),which is partly covered by the iris (white). The lens focuses light on the retina (orange) at the back of the eye. Light sensitive cells in the retina transmit impulses to the brain via the optic nerve (yellow at lower right). Behind the retina is the choroid (purple),which contains blood vessels that nourish the back of the eye. The outer layer is the sclera (dark brown),the white of the eye. The eyeball is filled with a gelatinous substance called vitreous humor. Several muscles hold the eyeball in place and allow it to rotate | |
