When I was in medical school they taught us that the eye was basically an organ entirely closed off to the rest of the body. And that always confused the heck out of me, like, how? How does that happen? But it turns out my confusion was really just my bullshit meter going off. I'm glad to know about this new lymphatic drainage system, it makes so much more sense.

What always confused me about that is that I could look at my own eyes over years and see that SOMETHING was acting as a lymphatic drain — so I always took that as a “we don’t care enough to figure it out.”

Wtf?

I've read a lot about the eyes recently (medical issues) and it struck me as odd that the eyes are described as having a largely separate immune system.

Like how??

Have you noticed yet the pervading visual noise that sits at the very front of your vision?
The colorful shifting shimmers that play on even in the dark.
Ya know, eye tinnitus.

If you’ve got excess floaters you should have your eyes checked. It can be an indication of something else going wrong.

POV, you’re degaussing your eyes:

Macular degeneration for one.

I have this when I'm not feeling mentally well. The visual noise is actually a sign for me that I should be extra careful to be nice to others because it's not them who are more annoying today, it's me.

You are degaussing your eyes like this:

I am degaussing my eyes like this:

This. I have bilateral PVD's. My retina guy said all the gunk would eventually dissolve.

It’s been almost fifteen years. It has not dissolved.

you may see bright lights, wavy or jagged lines, flashing dots or sparkles

I wouldn't describe my symptoms like this but I need to read more about this in my native language. Thanks!
