Can the light outside the human visible spectrum damage our eyes?

Question

We’re often warned about how dangerous small commercial lasers can be for our eyes yet technologies like FaceID projects light in our faces many times a day.

Why is FaceID safe? Because it’s low enough power or because it’s in the non-visible spectrum?

Can the non-visible spectrum be dangerous for our eyes?

Answer 1

yes. I remember working with a high power laser that was barely outside the visible range. The power is so high, the scattered reflection can blind you. As someone described it – if you go into the room without protection your sight will just turn into blackness forever.
