To see color, we need an iris. The circular band that is called the pupil also allows us to see color. The more pigment you have in your iris, the more color you’ll have in your eyes, and vice versa.

The pupil is an opening in the iris and becomes wider in dim light and narrowed in bright light.
The pupil controls the retina. To allow light into the retina, the pupil grows bigger to let light in.
The pupil is kind of like the police of light, because all light passes through the pupil before going anywhere else.

You can see through the cornea, which is perfectly curved, and there is little disfiguration and weakening of an image. The cornea is made of 5 layers. The cornea is always moist because of tear glands and is very, very sensitive.
The cornea is in front of the sclera.
