what’s the purpose of the gunk that ends up in you’re eyes when you sleep and what’s it called ?
In: Biology
My understanding is that it doesn’t have a purpose; it’s a side effect of the fact that you’ve had your eyes closed all night.
Rather than your tears being distributed over the eye with motion/blinking, they’ll just pool around the tear ducts. Then they dry out, leaving a residue of salt and mucus.
Not sure if there’s a scientific name for it as it’s just dried up tears.
