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?

Im guessing somewhere along the lines of because it takes muscle control to keep your eyes / eyelids open and would be taking in visual information (unless wearing sleep mask), continuing to use those muscles & having that visual input would prevent you from falling asleep … maybe … 😂
