There is a correlation between clear blisters on the eyelids and localized blockage of the glandular opening, which can be caused by bacterial infections, viral infections, and allergic reactions. 1. Bacterial infections: Bacterial conjunctivitis is associated with eye rubbing, which directly affects the smoothness of the glandular opening and leads to clear blisters in the eyelid. 2. Viral infections: Most of them are caused by herpes virus infection, which is related to the decrease of body immunity. Infection with herpes virus leads to the decrease of body immunity, and the symptom of clear blisters in the eyelids may appear. 3. Allergic reaction: mainly related to their own physical condition, after contact with allergens (pollen, etc.), the local tissue exudation is obvious, which will cause corresponding changes. The growth of small transparent blisters in the eyelids requires timely medical observation and standardized treatment under the guidance of the clinician.
