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.
Causes of watery eyes can include: 1  Dry Eye Syndrome. 2  Clogged tear ducts. 3  Conjunctivitis. 4  Environmental irritants such as chemicals, smog, hot wind, bright lights, blowing dust, and airborne allergens. 5  Blepharitis. 6  Abrasions. 7  Foreign bodies. 8  Allergies to mold, dust, and dander.
