There's a gland named meibomian in our eyelids, its function is to secrete boogers. The boogers are the thing that used to protect the erosion of tears to the eyes skin and the evaporation of tears which leads to dry eyes. The normal eyes have little boogers. But some people have too much and it even make the eyelids hard to open. The reason is the inflammation which has leaded by virus infection.

The rheum that comes from the eyes and forms eye boogers is called gound, which you may know as eye sand, eye gunk, sleep dust, sleep sand, sleep in your eyes, or eye shnooters. When you're awake, gound doesn't cause any problems. You don't even know it's there because it gets cleaned away whenever you blink. Your eyelids regularly corral it down to your tear ducts, where it's washed away. When you sleep, though, you're not blinking, and gound is allowed to build up in the corners of your eyes. It dries out and hardens, leaving you looking like you face planted in a sandcastle sometime during the night. Gound isn't a big deal for most people, but an unlucky few have a major problem with it.
