Infants always rubbing their eyes may be caused by dry eyes, inverted eyelashes, conjunctivitis and other reasons. 1. Dry eyes: infants will rub their eyes when both eyes are too dry. As the tear film is exposed to the air, it will lead to dry eyes and cause discomfort, so infants are always rubbing their eyes. 2. Inverted eyelashes: Eyelids with more fat and thicker eyelids can easily cause eyelashes to curl inward, causing inverted eyelashes. Inverted eyelashes irritate the eyes, so babies always rub their eyes. 3. Conjunctivitis: If an infant has conjunctivitis, it can cause discomfort, so the infant is always rubbing his eyes. There may be other reasons why babies always rub their eyes, so it is recommended that they go to the hospital in time, complete the examination to clarify the cause of the disease, and then give targeted treatment or therapy.
