The patient sleeps at night with especially heavy eye droppings may be caused by entering dust, or it may be caused by bacterial conjunctivitis, lacrimal sac infection and other factors. 1. Entering dust: If you stay in a dusty environment for a long time during the day, it may lead to some fine dust entering into the eyes, and then the eyes discharge the dust through autocrine secretion after sleeping at night, thus showing the performance of having a lot of eye boogers. 2. Bacterial conjunctivitis: if the patient’s conjunctiva is attacked by various bacteria, it may produce purulent inflammation of the conjunctiva, resulting in yellowish-white secretion, which leads to more eye droppings when the patient wakes up after sleeping. 3. Dacryocystitis: If the patient’s nasolacrimal duct is obstructed, resulting in tear retention in the lacrimal sac, the inflammatory reaction caused by the patient, the patient can thus appear eye congestion, swelling, as well as overflow of tears, mucous and purulent secretion flow and other uncomfortable symptoms. It is recommended that patients with increased eye discharge should seek medical attention to assess their condition and follow the doctor’s instructions for treatment.
