Have a hard time breathing on the moon that way, but OK...

I am aware of this. It is the means the eyes use to quickly adapt to 
changes in illumination. It has limits though, and doesn't account for 
the whole adaptive response, it can take hours to fully adapt. It 
doesn't really have anything to do with dynamic range, the range of 
illumination the eye can respond to at one time.
The pupilar response is the reason I referred to glancing out the door. 
It would only take a few moments for substantial adaptation to occur, so 
you would have to do it quickly enough that your eyes were mostly 
adapted to the room.

And you said the stars were invisible. I said they are visible, not that 
it was optimal viewing conditions. (though if you shield the sun and 
surroundings, it is ideal)
