Sleepies, eye gunk, eyeboogers… Whatever you call them, the proper name for that gunk that collects in the corners of your eyes is rheum. It’s exuded from your eyes while you sleep (as you know) but also your nose and mouth. When it comes from your eyes it’s primarily made of mucus discharged from your cornea or your conjunctiva. It doesn’t only happen when you’re asleep though! During the day our blinking flushes the mucus away into the nasolacrimal duct along with your tears over the Habs losing again.
If you have more rheum than most, you may be suffering from one of a few different conditions. Conjunctivitis (pink eye), chlamydia, infection of the eyelid (blepharitis) and more can all cause an excess of rheum, especially in your eyes.
If you’ve ever woken up unable to open your eye for the amount of eye goop present, you’re not alone. Not only because it’s happened to me several times, but also because it is a very common side effect of pink eye.
