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.
One official name for eye boogers is rheum. Rheum is the natural discharge of the eye, formed from a combination of mucus, tears, dust, and even skin cells from the eyelids. The eye produces rheum all dayâ¦ so why does it build up overnight? When weâre awake, blinking washes rheum and tears away so we donât get a buildup of sleepies.
