Light enters the eye through
the clear outer dome (the cornea) and passes 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.
