of the Eye
| How the Eye
The eye is like
a camera. When you take a picture, the lens in front of the camera
allows light through and focuses the light on the film that covers
the back inside wall of the camera. When the light hits the film the
picture is taken. The eye works in much the same way.
The front parts
of the eye are clear so the light can pass through to the center of
the eye called the vitreous cavity. The vitreous cavity is filled
with a clear, jelly-like substance called the Vitreous. The cornea
focuses the light and the lens on to a thin layer of tissue called
the Retina, which covers the back inside wall of the eye. When the
focused light hits the Retina, a picture is taken. Messages about
this picture are sent to the brain through the optic nerve. The brain
intercepts this message and this is how we see.
