So the energy is not being distributed throughout the body.

The energy is hitting the skin and you're getting an inflammatory response to it.

Now, interestingly...

we block those from our eye because our lens and our cornea also blocks those short wavelengths.

So that's part of the reason why we don't see them.

But it's also the reason why, for instance, people get snow blindness because it's just sunburn on the cornea and the lens.

It's recoverable from, but it's very painful.

It does.

And I've heard that described as being the lens being cooked.

But in actual fact, you know, I used to run the eye bank at Moorfields Eye Hospital, Eyes for Research.

And you can actually open a –

patient's eyes up when they're dead.

And you can look at the color of the lens and you can get a rough idea of how old that person was.

So one of the surgical procedures that medics love is to replace a cataract, take an older person, they've got this thick brownish lens, and pop it out and put a clear lens in.

And the instant response in 90% of them is, wow,

in the patients.

Yeah.

These are live patients.

Live patients, it's done under a local anesthetic in older patients.

They just go, wow, isn't that amazing?
