If people had sex by touching their eyes together, we’d probably see more. Otherwise, it’s hard for an eye only disease to spread.
SpongeBob SquarePants and Midoriya Izuku probably have to worry about eye infections, since in their worlds you can cry with the force of a yard sprinkler.
Because that immune system(if one wants to call it so) is within the eyeball,not on the outside. Lacrimal immune response is something else again.
Overall:
It’s called Immune privilege and is present in the central nervous system, the uterus and the testicles as well.
It’s nowhere near as extreme as the comment OP posted thinks it is - if you think about it closely it doesn’t make sense.
The interior of the eye is highly vascularized and of course “regular” immun system parts go through that.
In reality it’s more like"the eye" has an “extra Immunsystem” that helps it keep its special structures functional. Both alone as well as with the help of the body’s main system.
I don’t know about OP, but I tend to close my eyes when I sleep

But if a bear wakes you up in the middle of the night, it’s pretty helpful to have your eyesight maintained, even while sleeping, in order to just wake up and go

I’ve never been wakened by a bear, but so many times by babies! Not lately, bc I’m old and they somehow survived to adulthood. But I’m glad my sleep deprivation was not compounded by blindness.
Yeah. Plus sleeping with their pet human probably didn’t do you any favours

You still have vision even when your eyes are closed, and even the small amount of light that gets filtered through your eyelids as the sun rises in the morning is a significant enough stimuli to trigger the biological responses that are related to regulating sleep and managing your circadian rhythm.

Why don’t we see a lot of common infections that specifically affect eyes? Is the immune system that effective even though it can’t fuck your shit up?
Conjunctivitis

You seem to know what you are talking about but the other guy skimmed a wiki article after a brief web search, so I’m not sure whom to trust.
Well, I am a healthcare professional,but not your HCP and you won’t be able to know if I say the truth here either.
So the easiest way for you is to read the wikipedia article or the MSD manual,etc.

…or bears.
Maybe you shouldnt have eaten their porridge and slept in their bed.
