As I understand it the pupil opens up very quickly. If you walk outside into a dark area after being indoors in a bright room, your eyes will often be unable to pick up any stars (or anything else), but wait a few seconds and they start to appear. But you are nowhere near dark adapted, all that has happened is your pupils have opened up. But try walking around (as I have done at star parties a few times) and you are dangerous. Ten minutes later when the bio chemical dark adaption starts kicking in you can start seeing much more and 30 minutes later it is about as good as it gets.
Anyway that is my experience.
