Squeezing eyes of small children may be caused by inverted eyelashes, refractive errors, conjunctivitis, tic disorders and so on. 1. Inverted eyelashes: Inverted eyelashes are usually caused by congenital developmental abnormalities. The eyelashes on the edge of the eyelid do not point straight ahead, but pierce into the eyeball. Blinking and eye rotation will scratch the corneal epithelium, causing a foreign body sensation in the eye. 2. Refractive error: Children with refractive error may squeeze their eyes because they can’t see clearly, because squeezing their eyes can temporarily improve their vision. 3. Conjunctivitis: When a child has conjunctivitis, the inflammation will lead to foreign body sensation, itching and other symptoms, which will cause the child to squeeze his eyes. 4. Tourette’s syndrome: Children with this condition can also have symptoms of eye squeezing, but it is usually accompanied by other symptoms of facial muscle twitching. When a child’s eyes are squeezed frequently, he should go to the hospital in time to clarify the cause of the disease and follow the doctor’s instructions for treatment.
