It is time to understand the crusty stuff that is usually located at the corner of the eye when you wake up. It is called sleep crust or eye gunk. It is actually made up of mucus, exfoliated skin cells, oils, and tears produced or shed by the eye during sleep.
While we are awake, the process of blinking flushes out normal mucus produced by the conjunctiva, secretions from the meibomian glands, and other debris from the front surface of the eye.
Because we do not blink during sleep, eye discharge collects in the corners of the eyes and along the eyelash line. This eye discharge is what we therefore see as eye crust upon waking up.
Eye Crust are not harmful, however when you wake up with discharge from the eye such as yellow or some sticky discharge, it may be an indication of an eye infection and you should visit the clinic.
When next you wake up and you notice eye crust on the eye, just wash your eyes with a clean water or clean with a neat damp towel and your eyes are free of crust.
