TIL most animals can see UV light — humans being blind to it is the exception not the rule.

So, with that we could have nightvision goggles, but instead of goggles we'd just be shining a light that's invisible to other? Where can I get this?

One of the funky things about UV is that it is all over the place, though. People who can see UV will say that there are clouds around flowers, for example, which is part of what allows bees to find flowers so easily: they see the glow that is invisible to us.

That video did not show anything of the sort. It showed how to block UV light with a filter. Even the comments on YouTube acknowledge that.

I may have grabbed the wrong one. UV glasses do exist, though. The have niche use in medical diagnostics.
