Infants with heavy and yellow eye droppings may have blocked nasolacrimal ducts, colds or acute conjunctivitis. Normal human beings produce tears every minute, which moisturize the eyes and keep them bright. In some babies, the nasolacrimal duct is blocked by a membrane, so the tears of these babies cannot enter the nasal cavity in time, and more eye droppings are formed in the eye socket. If the baby has a cold, bacteria or viruses may infect the nasolacrimal ducts, causing secretions to appear at the openings of the ducts, and the baby will have heavy, yellowish eye droppings. Tears in the eyes of the child can not flow out, is a good petri dish for bacteria, there is the right temperature and nutrients will rapidly multiply, and then form pus, resulting in acute conjunctivitis, the baby’s eye boogers are many and yellowish. Babies with eye abnormalities need prompt medical treatment.
