The reason why children keep rubbing their eyes may be visual fatigue, inverted eyelashes, allergic conjunctivitis and so on. 1. Visual fatigue: If children recently watch TV, computer or cell phone and other electronic products for a long time, resulting in a significant reduction in the number of blinking, resulting in a reduction in tear secretion, the child will be dry eyes, eye astringency and other symptoms of discomfort and have been rubbing the eyes. 2. Inverted eyelashes: When children have inverted eyelashes due to lower eyelid redundancy or congenital entropion of the eyelid, the eyelashes will grow backward and grow to a certain length, which will irritate the cornea and conjunctiva, resulting in eye discomfort, and so children can appear to have been rubbing their eyes. 3. Allergic conjunctivitis: If the child’s conjunctiva is stimulated by allergens such as dust, willow flakes, animal dander, etc., causing local allergic reactions, histamine and other immune factors stimulate the conjunctiva to cause discomfort, which can lead to the child’s eyes rubbing all the time. It is recommended that children with frequent eye rubbing and other discomforts should consult a doctor to assess their condition and follow the doctor’s instructions for treatment.
