*There are parts of you that are strangers to the rest of you – Your eyes have immune privilege.
This means your immune system does not know they exist.
They live in secret behind a blood tissue barrier – If that barrier breaks from a bad hit or a cut, the secret gets out.
The white blood cells rush in.
They see the eye tissue not as self – but as a foreign invader, they attack it.
They try to dissolve it like a virus.
They don’t just kill the injured eye.
They remember the shape of the enemy – they now travel to the other eye, the healthy one.
They attack that too.
You can go blind in both.
Because your body decided to fight a war against its own vision.
A betrayal set in your blood – a rare thing , but it happens.
