Under normal circumstances, people blink about 15 to 20 times per minute. By blinking, the tear film is evenly coated on the eye surface, and foreign substances and secretions are washed away from the eye surface, thus protecting the eye surface. However, if blinking is too frequent, it may be a pathological phenomenon. Doctors sometimes encounter this condition in ophthalmology clinics, especially in children between the ages of 3 and 15. So let’s look at the frequent blinking of the baby, what are the main causes? 1, congenital eye inversion or inverted eyelashes: oriental people because the facial soft tissue is more bloated, coupled with children’s facial bones are not yet fully developed, congenital eyelid inversion is very common, because the eyelashes are inverted on the surface of the eye, stimulating the cornea will cause blinking and tears and other phenomena, eyelid inversion, many will gradually reduce as the child grows up, to about 4 years old self-healing, but in serious cases will need to be corrected through surgery The problem can be corrected by surgery. 2, habitual blinking: within the age of 3 years old infants and toddlers stage is relatively rare, 3-6 years old children are relatively common, this age group of children imitation ability is relatively strong, so in the surrounding people or objects under the influence of easy to produce this situation; performance for children usually nothing unusual, there are adults or outsiders present in order to attract the attention of adults and squeeze eyebrows, or around there are frequent blinking people, children imitate him. As a result, the child slowly develops a habitual frequent blinking. In this case, the parents should remind the child and help the child to self-control and gradually improve or cure. 3, eye inflammation or foreign body stimulation: due to dusty weather, or due to unclean hands rubbing the eyes and other bad habits, resulting in infection due to bacteria, viruses, chlamydia, or foreign bodies splashing into the eyes and causing keratitis or conjunctivitis, can also cause children to blink frequently. In addition to frequent blinking, there are also manifestations such as red, itchy eyes, increased secretions and tearing, and children over 5 or 6 years old may also complain of eye discomfort or eye pain. 4, eye fatigue caused by blinking: some children due to prolonged use of electronic products such as television, computers, cell phones, pads, etc., there are different degrees of dry eye symptoms, mainly manifested as dry eyes, itchy eyes, burning foreign body feeling, blurred vision, vision loss, eye swelling, orbital pain and other symptoms. In this case, the child’s school life should be properly arranged, so that the child should not exceed 40 minutes of continuous close eye use, minimize the use of electronic products (the total time should not exceed 1 hour per day), optometry and glasses if necessary, and timely detection of refractive error and other pathological conditions, so as not to affect the child’s vision development. 5, children’s tic disorder: children’s tic disorder is a multi-group muscle involuntary twitching, in the eye mainly manifested as frequent transient or involuntary transient, in addition, can also be accompanied by multi-site twitching or compound motor twitching, such as frowning, crooked mouth, shrugging shoulders, as well as inattention and hyperactive behavior change, some children will also make strange sounds, and even cursing, swearing, etc.. This disease seriously affects the child’s normal life, learning and mental health, in the treatment to correct the main, parents should actively cooperate with the doctor, timely remind and help the child self-control, but do not be too hasty, do not reprimand the child scold, so as not to cause the child’s psychological tension and aggravate the disease. 6, lack of nutrients in the body: reflex transient purpose of the afferent path is the trigeminal nerve, the efferent path is the facial nerve, mainly by the innervation of the cerebral cortex. If the child is a long time paranoid and picky eater, it may lead to a lack of certain nutrients in the body, especially when there is a lack of vitamins and trace elements, which can cause an increase in neuromuscular stress and lead to neurological disorders, and then frequent blinking. In conclusion, the causes of frequent blinking in children are many, and the treatment is also different. Once parents find that their children blink frequently, they should seek medical attention as soon as possible in order to treat the problem symptomatically, and in the process of treatment, parents should first eliminate the reinforcing effect caused by their own excessive attention. Encourage the child to participate in various activities of interest and to develop a regular routine and good eating habits.
