We just learned about the Cornea.

Another part of the eye is the Retina.

Remember that the black pupil in the eye is really just a hole for the light to come in.
The black color of the pupil comes from the inside of the eye, where the light hits the retina.

The retina is in the back of the eye.
Inside the eye it is shaped like a ball, with the pupil as the hole to let light in, and the retina as inside of the ball at the back.

The retina helps take the light that shines on it, and turn it into signals that are sent to the brain so you can understand what you are seeing.
