The color of our eyes doesn’t matter much. The light goes into our eyes through the pupil, which is the part that looks black.

Think about a doorway into a dark room. The part of your eye that is blue or brown, or some other color is like the doorway. It is called the iris. The iris can get big to let in more light, or small if the light is too bright. It does not change the color of the light that goes in.

The pupil is the hole that lets light in. The pupil looks black because it is dark inside your eyeball.

Try this. Have a friend sit in a dark room for a few minutes. Then add just enough light so that you can see their eyes. Don’t shine a light right at them. Now have them go out into a sunny day. Look at your friend’s eyes. You should see the pupils get smaller as your friend goes into the bright sun.
