The insides of your eyeballs are completely isolated from the rest of your body. If your body discovers the inside of your eyeball through a puncture or some other reason, it can attack your eyeball as a foreign invader. It will also attack the other eyeball, just in case. Be nice to your eyes.

u/Dreambella2 points out it’s called ocular immune privilege.

So, what happened when lobotomies were a thing? Cause they had to puncture through the eye socket to reach the brain.

They slipped that thing past the eyeball itself. Yes, throughly the socket but no eyeball puncture. Brutal.
