Why is sleep so related to our eyes?

Is this kind of baffling to anyone else?

When I get tired, the only one of my five senses that “feels” tired is my eyesight, it’s not like my taste or hearing noticeably declines. And when I go to sleep, it’s critical that my eyes have zero stimulus, I can sleep with a smell or (maybe to a lesser extent) sound in the room just fine.

What’s so special about eyesight in relation to fatigue?

I’m a night shift nurse, and sometimes my sleep schedule is so jacked up that I might go 24 hours before I can fall asleep again (that includes my 12+ hour work shift).

When I get to really extreme stages of fatigue, my sense of smell and taste lessen but my desire for fatty and salty food increase. I haven’t noticed any change in my hearing, but my sense of motion and balance is affected; it’s almost like a mild vertigo, which can be especially scary if I’m trying to drive home. However, once I’m at home in bed, it can take a while to fall asleep, because the bed itself is TOO still. It’s almost like I need something in motion to compensate for whatever is going on inside my head.

So I’m not sure if this is specifically what you were referring to, but these are the effects I notice when I am much more fatigued than usual.

As I understand it tired eyes it just the first sign of fatigue.
And ignoring the fatigue long enough will lead to exhaustion, which has a lot more lousy symptoms, with more of the other senes kicking in screaming for you to rest.

We’re primarily a visual species, so it makes sense that our primary sense is the one most related to fatigue.
