Not our safety, but that of what they are filming. Some of these things never see the light of day and James Cameron over here is blasting it in the face with what must feel like the light of a billion suns, how does this not damage the eyes of the animals that have them?
In: Biology
The answer is actually already ELI5 easy – they’re deep sea animals, so they’ve never had light, so they don’t really have eyes. This makes sense if you think about it – if you lived in total darkness for your entire life, what good would it do you to be able to see anything? So, those animals simply evolved away from needing vision the way we do.
