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.
Eye boogers can also accumulate on the outer corners of the eye or anywhere along the lash. There's also the question of its consistency -- sometimes eye boogers are wet and sticky and other times they're dry and sandy. Does this depend on how long they've sat there or how much sleep you've gotten? Chen says the texture is a function of a person's tear film.
