Just curious...

Does anyone out there know how bright is too bright? What amount of light will cause permanent eye damage? Also, how long could you look before the retinas are damaged?

Let's say that you're looking (eyes open) into a light that is held 1 arm length away.

I know that it can be caused by lasers and by looking at the sun (though I don't know what part of the spectrum is responsible for the damage).
