This clear structure focuses light rays onto the retina.
This clear, dome-shaped covering in the front of the eye acts
as the eye's outer lens. Much like a window, the cornea controls light
entering the eye. It also helps the eye focus.
The iris has muscles attached to it that change its shape.
This allows the iris to control how much light goes through the pupil.
This nerve layer lines the back of the eye. The retina takes
the light the eye receives and changes it into nerve signals so the
brain can understand what the eye is seeing.
This bundle of over a million nerve fibers carries electrical
signals from the retina to the brain to be translated into the image
that we see.
The layer of the eye that provides oxygen and nutrition to the outer layers of the retina.
Contains a muscle that contracts and relaxes and allows the lens to change shape so the eye can focus.
The transparent, jelly-like substance that fills the space between the lens and the retina.
The white protective outer covering of your eye.
