​​Why do you get Boogers in your Eyes?

The scientific name for eye boogers is rheum.
Rheum is made up of mucus, skin cells, oils and dust. 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. When you're awake, gound doesn't cause any problems.
Your eyes produce mucus throughout the day, but a continuous thin film of tears bathes your eyes when you blink, flushing out the rheum before it hardens in your eyes.
When you're asleep  and not blinking, eye discharge collects and crusts in the corners of your eyes and sometimes along the lash line, hence the term "sleep in your eyes."
Eye discharge is a common symptom of conjunctivitis.
In addition to conjunctivitis, there are many eye infections that cause abnormal eye discharge. These include: eye herpes (a recurrent viral eye infection), fungal keratitis (a rare but serious inflammation of the cornea) and Acanthamoeba keratitis (a potentially blinding parasitic infection typically caused by poor contact lens hygiene or swimming while wearing contacts).
