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?

I don’t know anything about it but I had this guy my basic training flight that slept with his eyes open almost every night for the entire time I was on watch (abt two hours).
