The Human Eye: OVERVIEW
The eye has been called the most complex organ in our body. The eye is like a camera.
It lets light in through the cornea, which is like a camera's aperture.
The amount of light allowed in is controlled by the pupil, which opens
and closes a bit like a shutter. The light focuses on the retina,
which sends the image to the brain, acting as film would in order to
record the light (the photo itself).
Other eye structures support the main activity of sight: Some carry fluids
(such as tears and blood) to lubricate or nourish the eye. Others are muscles
that allow the eye to move. Some protect the eye from injury (such as the lids
and the epithelium of the cornea). And some are messengers, sending sensory
information to the brain (such as the pain-sensing nerves in the cornea and the
optic nerve behind the retina). |
