It uses some near-infrared light and a little bit of kind of a yellow light.

But they shine that in the eye in intervals and they do it for a few weeks and then a few months you do it again.

And for macular degeneration, they've been able to show that not only can the protein that builds up in the back of the eye in that condition diminish, but they can slow down and slow down the progression of macular degeneration.

And for some people, even restore eyesight.

They can actually help people see better.

Using that form of red light therapy.

Don't.

So the challenge is...

sunlight is good for the eyes, especially early on in the day and, of course, toward the end of the day, just so that you're getting the signals to your brain to, hey, the sun is coming up, the sun is going down, a way to kind of influence your melatonin production.

The staring directly into the sun, though,

The sun is so powerful, it can very quickly burn holes inside your retina.

And I have a patient right now who she comes in, her vision is not getting to 20-20.

We look inside the eye and she has burn holes, a burned hole in her retina that we diagnose as solar retinopathy.

And I'm like, have you been staring at the sun?

She's like, yeah, I've been sun gazing since I was little.

I was in Florida recently and I stared at the sun.

And I was doing this for how many minutes?

And...

Now she has permanent blind spots where she cannot see 20-20 anymore.
