Here's how fucked up it is imagine the only difference between having eyes and not having eyes is one tiny small area that if it breaks at any moment the immune system can "find" your eyes which is why eye damage needs to be treated right away. One tiny barrier keeps your eyes from being identified and if that breaks your worst nightmare.

It's like the brain. There's a tiny barrier that keeps the immune system out of it, and it breaking down is thought to be the cause of a few major brain conditions.
