2. Do you have any control over your pupils when
they dilate? We don't have any control. I think we don't have any control because if we forgot to make our pupils smaller or bigger it could cause instant blindness, like if we had control of our heart and we forgot to pump blood through our body we would be dead, so I think it is good that we don't have control.
3. What do we call this when a reflex happens without our control?
4. Why do our pupils get bigger in the dark and smaller in the light? They get bigger when you can't see (when your in the dark). They do this because your eyes want to see so they try to let more light in so we can see what we are doing and where we are going.
5. How does this reflex protect our eyes? Like I said on question 2 if the reflex doesn't kick in it could cause instant blindness. If your in the dark you would not be able to see a thing and that can be hurtful too.
