Why do infrared lasers pose a threat to your eyes? I understand that since it is invisible, we don't realize how powerful it is, but doesn't it being invisible make it not damaging to our eyes?
What I'm trying to say is, our eye sees the colors we see because it absorbs those colors, just like a green sheet of paper reflects green, but no other colors. I'm curious as to how infrared can be damaging to vision if our eyes don't perceive it.
There most be some limit to which higher wavelengths do no damage right? Like maybe 808nm is bad for the eyes, because it's so close to visible spectrum, but what about (just random) 1400nm?
