Can I See More Stars With My Eyeballs?

If you look up at the sky and it's bright out, then your pupils will close a little bit rikht. So during the day, that shrinks. And so you're actually less sensitive to really dim objects. That's why you can see dimmer things at night, because your eyes have opened up to let in more photons. If you looked up at the sky in the middle of the day with your eyes on like night vision mode, you could damage the back of your eyeballs. Yet, don't look at the sun, please. This is an experiment suggestion here.
