Can a bright light outside the visible spectrum hurt your eyes?

For that matter, what exactly's happening when a bright light "hurts"?

Yes.  Absolutely light outside the visible spectrum can be harmful.  Both visible and other than visible light can be harmful, but in both cases, it depends on the intensity.  The reason outside-visible light (such as UV/IR) can be much more harmful is because you can't see it so you don't blink to shield yourself and it can cause much more harm before you even know it.
