1. Can you feel it when your pupils dilate?
2. Do you have any control over your pupils when they dilate?
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?
5. How does this reflex protect our eyes?
1.No Because you cant feel it when your muscles contract and make your eye open up. Also because you are just letting light in.
2. No because your pupil automatically knows that it has to get bigger to let light in. Also because your rods in your eye know that they need more light.
3. An Involuntary reflex automatically does something without thinking. Meaning that your brain doesn't tell your muscles to move.
4. Our pupils do that because they need to let more light in so we can see. Also if they let in too much light it could hurt our eyes.
5. This reflex protects our eyes so the light doesn't burn our rods and cones. If are rods and cones die we would be blind.
