Ah, thanks. I'm surprised I haven't heard of body modders getting that done so they can see UV, that sounds like a neat superpower akin to people who get magnets embedded in their fingers. Going to research risks now..

I'm going to guess the retina doesn't hold up to UV exposure too well. Seems very likely.

You would be right in the case of UVA light [1]. Though it's interesting that we have photoreceptors for UV light in the first place.
