Consider conjunctivitis as the cause if there is increased discharge after sleeping. If there is a noticeable increase in yellowish-white discharge from the corners of the eyes, or even after waking up from sleep, you find that the upper and lower eyelids are sticking together and you cannot open your eyes, consider bacterial conjunctivitis, which is mostly caused by Staphylococcus aureus infection. After diagnosis, pay attention to eye hygiene, rinse the secretion with saline, and treat with antibiotic eye drops and eye ointment, such as tobramycin eye drops and erythromycin eye ointment. If there is an increase in white filamentous discharge with itching while sleeping, there is a possibility of allergic conjunctivitis, which may be an allergic reaction caused by contact with certain allergens. After diagnosis, try to avoid contact with allergens and treat with anti-allergy medication, such as emamectin fumarate eye drops. If there is often a small amount of discharge when sleeping, it may be chronic conjunctivitis, so you should develop good habits, along with antibiotic eye drops treatment.
