Eyes [īz]
Globular organs in the head through which people and animals see.

The eyeball is a sphere, about 2.5 cm (1 inch) in diameter, set in a protective cone-shaped cavity in the skull called the orbit or socket. Our eyes change light rays into electrical signals that are sent to a special part of the brain, which interprets these electrical signals as visual images.
