Why does the pupil get smaller when a bright light is shone in the eye?
Our pupils adjust to absorb enough light to see, but not so much that it damages our eyes. So when a bright light is shined in the eye, the pupil closes so that the eye isn't damaged. That's why doctors make you wear sunglasses after they dilate your eyes.

Does a raccoon see in the dark?
The special thing about their eyes is that they can see in both night and day. The raccoon is primarily a nocturnal animal. The raccoon's eyes have a little mirror in the back of the eye. The light that comes during the night is absorbed by the raccoons eyes. Some light doesn't get absorbed. The mirror reflects the little light that doesn't get absorbed. When the light gets reflected the raccoons eyes have another chance to absorb it.

How do your eyes pick up light waves?
The light travels into you eyes through the pupils. Because light is a wave it gets focused at different points on the back of your eye depending on where it came from. The energy of the wave activates rods and cones and electrical signals get sent to your brain.

What is similar between a camera and an eye?
the hole in the front of a camera can be made bigger or smaller to control how much light gets in. Your eyes work in a similar way. To much light can damage your eyes, so your pupils get smaller when it is very bright and in dim light your pupils get very bigger to let more light in
