Light enters
the eye through the clear outer dome, the cornea, and goes through
the pupil. The lens is just through the
pupil: it transmits and focuses images on the retina, which is like film
in a camera.
The macula is the central receptor site of the retina and provides our sharp
vision for tasks such as reading and driving. The retina sends
the images via the optic nerve to the brain for processing.
