     Have you ever thought about how you can see things and how the light passes through your eye?  Well, today I am going to explain the process of light passing through to your eye.  Everybodys eyes are about an inch in diameter; they each have a cornea and a pupil.  But, how does the light pass through?
     The light passes through by going through the cornea all the way to the optic nerve of your eyeball.  It then goes through the retina, the inside back wall of the  eye.  Your eye works like a camera, but it is more complex.  It is able to turn the image you see upside down in order to see it correctly.
