The cause of eye boogers in the morning may be a normal physiological phenomenon, or it may be a pathological factor, such as allergy, dry eye, conjunctivitis, keratitis, etc.. 1. Physiological phenomenon: some cells and glands in the eyes can normally secrete oil, protein and other substances, which can play a role in lubricating and moisturizing the eye surface. At night, these substances can gather in the corners of the eyes, thus forming eye droppings, which is a normal physiological phenomenon. 2. Allergy: some causes of eye allergies, such as air pollution, can lead to eye redness, swelling, itching, secretion increase, etc., may appear in the morning eyes with eye droppings. 3. Dry eyes: If you suffer from dry eyes, you may have eye droppings around your eyes in the morning, and they are dry, with less amount of eye droppings, which may be white and silky. 4. Conjunctivitis: Conjunctivitis occurs when the eye is infected by pathogenic bacteria, and the amount of eye droppings is more, yellow in color, thicker in texture, and sometimes the eye droppings will stick to the upper and lower eyelashes, making it impossible to open the eyes. 5. Keratitis: Keratitis can be characterized by redness and swelling of the eyes, increased secretion, foreign body sensation, photophobia, tearing, and even vision loss and blurred vision. Therefore, you can wake up in the morning with eye droppings. Remind patients: If patients find that there is eye droppings in the eyes in the morning, accompanied by other symptoms, such as redness and swelling of the eyes, it is recommended to go to the hospital in time for examination, to identify the causes, and symptomatic treatment.
