By me, an engineer who spent 6 years of my phd looking at human eye pathology + 15 years visiting optometry shops. I don't make any money on this. UV is bad.

So what are the uv light receptors doing in the eye and the skin?

There are no uv light receptors.

The thing I was thinking of is the POMC gene. It’s only stimulated by UV light and is in the retinal pigment epithelium. So in a way- there is a uv light receptor in the eye.

no, they aren't for sensing they are for chemical reactions

What the hell are you talking about?

You have UV cones in your eyes?

You must see a shitload of extra colours compared to the rest of us.

I saw a story about a woman with 4 colour cones, she could see like 10 thousand extra shades of green that normal people can't see. It's rare.

But a UV cone? In a human? Never heard of such a thing.

It’s called POMC and it’s in the retinal pigment epithelium.
