Blink more

Under normal circumstances, the interval between two blinks is more than a few seconds. If paroxysmal fast blinks occur, it is an abnormal phenomenon. Frequent blinking of children is common in clinical ophthalmology. There are several cases of frequent blinking of children. One is when the child's eye conjunctiva is inflamed, the child is uncomfortable, and the eye has a foreign body sensation. Through blinking and tear secretion, the foreign body sensation in the eye can always be temporarily relieved. This is the main reason. Another is that when the child has visual fatigue, this may also occur in cases such as refractive error. There is a child's neurological blink.
