the (eye) boogie man

Question: What causes and where do eye boogers come from?

Answer: There's a special little organ around your eye called the plica semilunaris.It's the crust factory. It secretes a sticky fluid that collects any dust or pollen that has migrated into your eye. All those foreign bits are surrounded by this sticky stuff, so your cornea doesn't get scratched. This little organ "escorts" that garbage out of your eye just like a security guard.
