ELI5, why can’t we sleep with our eyes opened?

Why can’t we sleep with our eyes opened?
I’m wondering… I mean, I know our eyes would dry out but there’s gotta be a bigger explanation?
I mean, why does our body feels the need to close it eyes? And can only rest with its eyes closed?

Could I trick my brain to sleep while my eyes are opened?

Some people can, but most can’t because in order to go to sleep you need to have a limited amount of action in your prefrontal cortex. Seeing and translating from the picture to what you are seeing requires a lot of action from your prefrontal cortex. You can train yourself to relax it enough to go to sleep.
