How
does the eye work?
Anything you see is an image that enters your eye in the form
of light. The different parts of your eye collect this light
and send a message to your brain, enabling you to see. For
perfect vision all the parts of your eye need to work properly.

Light
rays passing through a healthy Cornea
|
The cornea is the clear, outer
layer of the eye.
The pupil is an opening that lets light enter the eye.
The iris, the colored part of the eye, makes the pupil larger
or smaller.
The lens bends to focus light onto the retina.
The retina receives light that has been focused by the cornea
and lens.
A clear (vitreous) gel fills the inside of the eye, giving
it shape.
The cornea is clear to let light into the eye, and curved
to focus the light rays.
