Eyeball: the ball-shaped capsule containing the vertebrate eye
Source: WordNet 2.1
Eyeball: The eyeball is one of the sense organs and is responsible for the sense of sight or vision. The eyeball is located within the orbit in the skull. It is protected by the bones of the orbit and moves through the actions of the eye muscles. It is innervated by the abducens nerve, oculomotor nerve, and the trochlear nerve.
Within the eyeball there are many features that work together with the nerves of the nervous system and the eye muscles to create vision. These features are located within the three layers of the eyeball: the sclera, choroid layer, and the retina. Light flows through the cornea and the pupil of the globe onto the lens before it is projected onto the retina. The retina then transforms light into electrical impulses that can be transmitted by the ganglion neurons, which make up the optic nerve, to the nervous system.
Conditions that can afflict the eyeball include glaucoma, cataracts, trauma, ruptured globe, nearsightedness, astigmatism, farsightedness, presbyopia, and color blindness.
