The causes of eye droppings are conjunctivitis, blocked nasolacrimal ducts and inverted eyelashes. 1. Conjunctivitis: If the baby suffers from conjunctivitis, it will stimulate the glands on the surface of the eye to secrete more inflammatory secretions, and these secretions accumulate in the corners of the eyes to form more eye boogers, and most of them are yellow or watery. 2. Nasolacrimal duct blockage: if the baby’s nasolacrimal duct at the lower end of the nasolacrimal opening is closed by the congenital membrane tissue, that is, the nasolacrimal duct blockage, resulting in the conjunctival sac secretions can not be discharged smoothly, there will be a buildup of secretions in the corners of the eyes, secretions drying out after the formation of eye droppings. 3. Inverted eyelashes: If the baby has inverted eyelashes, i.e. eyelashes growing in an abnormal direction, the abnormally growing eyelashes can stimulate the eye surface and cause an increase in secretions, which will lead to the manifestation of excessive eye droppings. Small baby eye boogers may also be other reasons, persistent can not be relieved or accompanied by other discomfort, must go to the regular hospital to identify the cause of the disease, and actively cooperate with the professional doctor’s treatment.
