Blinking is an instinctive human action and is a normal physiological activity of the eye muscles. People reflexively blink when they feel uncomfortable or nervous, such as dry eyes or astringent eyes. Blinking is a protective mechanism that protects the eyes from stimulation by foreign objects and light, and also ensures that tears are evenly distributed to protect the cornea, avoid drying of the eye surface, and prevent damage from dust. Newborns blink 2 times per minute, and when they grow up, the number of blinks normally reaches 14 to 17 per minute. If the number of blinks greatly exceeds this frequency, it is pathological. What are the common causes and treatments for frequent blinking in children? 1, dry eye: now a variety of cell phones, game consoles, learning machines and iPads are widely used, due to image stimulation, TV screen flicker, change speed, not only lead to children’s visual center over-excitement, but also make the child transient eyes reduced, resulting in easy dry eyes, after a period of time will eventually appear to start blinking more. Resting with eyes closed will improve. There should be more contact and interaction with the child to avoid prolonged communication between the child and the machine. If it still does not improve, you need to go to the ophthalmology department. 2. Allergic conjunctivitis: Some children blink seasonally and often rub their eyes at the same time, complaining of itchy eyes and foreign body sensations, sometimes seeing mucous filament-like secretions and poor results with antibiotic eye drops. Allergic conjunctivitis should be highly suspected at this time, and can be confirmed if there are also symptoms such as sneezing, runny nose or an itchy throat. Careful parents may also notice a lot of “bumps” on the inside of the child’s eyelids. This is caused by the child’s allergy to certain substances, such as pollen, dust mites, etc. Antibiotic treatment will not only not improve, but sometimes aggravate the symptoms. Anti-allergy eye drops such as sodium cromoglycate drops or pyrimethamine potassium drops should be used. In severe cases, topical hormonal eye drops should be prescribed by an ophthalmologist and closely monitored clinically. At this time, children should avoid rubbing their eyes, and ice water can be used to wash the eyes to reduce the symptoms. 3. Infectious conjunctivitis: such as conjunctivitis and keratitis, may be related to bacterial, viral or chlamydial infections, and is mostly related to the child’s poor hygiene habits and frequent rubbing of the eyes with dirty hands. In addition to increased blinking there are also manifestations such as: redness, itching, increased secretion, and tearing of the eyes. For frequent blinking caused by bacterial inflammation, use levofloxacin eye drops or tobramycin eye drops 3 to 6 times a day, and antibiotic eye ointment such as erythromycin once a night. In severe cases, the frequency of eye drops can be increased to once every 1 to 2 hours. If the inflammation is viral, use ganciclovir or ribavirin eye drops to spot the eye 4 to 6 times a day. Systemic treatment is usually not necessary. Different infections may behave similarly, and it is best to visit an ophthalmologist for professional treatment. 4. Congenital entropion and inverted eyelashes: Some children have congenital entropion of the eyelids (medically called eyelids) or obesity causing the eyelashes to fall back on the surface of the eye and irritate the cornea (the surface of the black eye) causing tearing. This condition is most common in lower eyelids and can be detected by attentive parents. In mild cases, the eyelid can be gently turned out to its normal position and fixed by traction with tape on the local skin. In severe cases, surgery is required to correct the problem. 5, eye fatigue blink: including visual fatigue, such as refractive error, especially farsightedness, myopia, astigmatism caused by uncorrected eye visual fatigue and caused. This is a protective reflex, through constant blinking can adjust the curvature of the eye, so that visual clarity. In this case, you should arrange your child’s school life appropriately, tell your child that the time spent reading books and watching television and computers should not be too long, urge your child to do eye exercises, and if necessary, get an eye exam and glasses. 6. Habitual blinking: Some children have a history of frequent blinking due to one of the above causes, and through treatment, after the cause is removed, they still retain the habit of frequent blinking. Other children like to imitate other people’s frequent blinking because they usually don’t pay attention to it, resulting in habitual frequent blinking. Parents should promptly remind their children to help them control themselves. 7, temporary tic disorder: this condition is generally not very worrying, 4%C24% of school-age children will have this condition, involuntary eye muscle twitching, related to stimulation and stress, learning or mood discomfort. Sometimes the symptoms go away when the child is in a different environment, such as when you take him to the doctor. This condition usually subsides on its own, in about 1 month. If the child has had this condition for more than a year and has irritability, personality changes such as frequent strange noises, even cursing and swearing, this condition is medically called hyperactive obscene language syndrome in children. This disease seriously affects the normal life, learning and mental health of children. You should go to the pediatrician in time and cooperate with the doctor for treatment. Do not reprimand and scold your child, but gradually induce and patiently persuade him/her. As mentioned above, there are many causes of frequent blinking in children, and treatment is different and requires diagnosis and treatment by an experienced doctor. Parents should seek medical attention as soon as they discover that their child is blinking frequently to avoid aggravation of the disease. As long as they are detected and treated in a timely manner, the results are generally better.
