When the individual is awake, blinking of the eyelid causes rheum to be washed away with tears via the nasolacrimal duct. The absence of this action during sleep, however, results in a small amount of dry rheum accumulating in corners of the eye, most notably in children.
To prevent eye infections if you wear contact lenses, you should do the following: 1  Keep your lenses clean and always follow the instructions on the cleaning solution label. 2  Wash your hand before changing your contacts. 3  Donât sleep with your contacts as this could cause eye boogers in the morning.
