My understanding is that visible light is very safe because it takes a long time for damage to happen and you naturally protect yourself. Of course "burning an image" really just means causing your eye to perceive an after image.
Natural visible light, yes; even somewhat concentrated reflected sunlight will take more than a blink to harm you. Visible light in general, hell no it's not safe. For goodness' sake, be careful with your lasers. And beat the everloving crap out of anyone being casual with those damned bright green lasers, which are most emphatically not toys.
I'm not saying that this theater flashing stunt was dangerous, I doubt it was anywhere near dangerous, I'm saying the idea that all visible light is safe can get you blind.
Right yeah, absolutely. What I really meant was white light of a fairly broad spectrum, hopefully no one read my comment and thought it applied to visible spectrum laser light.
