Is the light that I see not the same light that another person sees?

The pupils take time to adjust...do you mean that when the light first turns on and off, people don't see the room and just see the bright flash and that's because the eye can't make out the details because it needs to adjust? Why do pupils need to be protected :o?
I mean, it makes sense pupils need to be protected, but why is light harmful? Is it like the sunspots thing where when I look at a super bright object I see a blob in my eyes for a while? What is that?
