obviously the human eye can’t zoom, but it can focus and take in a wide range of amounts of light. when using a camera lens, if you take a picture of, say, the moon, with an ISO that is too high, you’ll miss all of the craters and other detail. However, looking at the same moon with the naked eye, you can make out a lot of those details. is an eye just, like, a camera on auto? hopefully i’m being clear enough.

The eye will adjust its focus and exposure automatically. You won’t typically notice this, although or course you can see the dilation of your pupils in the mirror and with practice you can control focus manually.
With dilation you may be able to notice it from time to time if you pay close attention. My eyes are frequently dilated differently and when the difference is extreme they will just ‘feel’ different.
