If the baby always blinks, first of all, pay attention to whether there is redness, swelling, itching and pain in the child's conjunctiva. When suffering from conjunctivitis, it is likely to blink. If this problem occurs, it is usually caused by bacteria or viruses invading the conjunctiva. When a baby often rubs his eyes with his hands, or has close contact with some patients suffering from conjunctivitis, he is likely to be infected with this disease. Therefore, the child should take protective measures, try not to let the baby rub his eyes, which is conducive to reducing the incidence of conjunctivitis. If the child does not have conjunctivitis and other diseases, it is likely that his eyes are uncomfortable, or he often pays attention to the lights, resulting in fatigue or blurred vision. Because the baby is relatively small, he always pays close attention to new things, which is likely to cause eye damage. Especially if he often turns on the dazzling lights at night, he will attract the baby's attention and make him constantly look at the lights, causing eye damage.
