Parents often visit the ophthalmology clinic for their child’s blinking. In order for parents to understand this situation, whether or not they should be seen, where they should be seen, and what to look for in general, a brief overview is given. First, we need to understand why people blink. Blinking is an instinctive human action that is a normal physiological activity of the eye muscles. When a person feels uncomfortable or nervous, such as dry eyes or astringent eyes, they will reflexively blink, which are normal muscle activities. Blinking is a protective mechanism that protects the eyes from foreign objects, light and other stimuli, and also ensures that tears are evenly distributed to protect the cornea, prevent the surface of the eye from drying out, and prevent dust damage. Newborns blink 2 times per minute, and when they grow up, the number of blinks normally reaches 14-17 per minute. If the number of blinks greatly exceeds this frequency, it is pathological. So what exactly causes pathological blinking in children and what treatments are available? First, dry eyes Nowadays, children watching TV, computers, cell phones, game consoles, iPads, etc. have become an inevitable topic for parents, in which the image stimulation, the flickering of the TV screen, and the rapid speed of change not only lead to transitional excitation of the child’s visual center, but also reduce the child’s transient eyes, leading to dry eyes, and after a while they end up blinking frequently. Resting with the eyes closed tends to improve. Therefore, parents can increase mutual communication with their children and avoid excessive exposure to electronic products. If it still does not improve, go to the ophthalmology department as soon as possible. Allergic conjunctivitis Children blink seasonally and often rub their eyes, complaining of eye itching and foreign body sensation, sometimes seeing mucous-like discharge and poor results with antibiotic eye drops. If this is the case, suspect allergic conjunctivitis. If it is accompanied by sneezing, runny nose or itching in the throat, the diagnosis is basically confirmed. Antibiotic treatment will not only not improve, but sometimes will aggravate the condition. Anti-allergic eye drops should be applied at this time, and in severe cases, hormonal eye drops need to be used under the guidance of a physician. Third, infectious diseases Bacterial and viral infections may be related to the child’s poor hygiene habits and frequent rubbing of the eyes with dirty hands. In addition to blinking crooked eyes, there will also be signs of redness, itchiness and increased secretions in the eyes. This is when antibiotic eye drops or antiviral eye drops may be used. However, different infections may behave differently, and parents must take their children to the hospital if they cannot distinguish between them. Congenital lid entropion and inverted eyelashes Children with congenital eyelid entropion or obesity cause eyelashes to fall back on the surface of the eye, irritating the cornea and causing tearing. Entropion is common in the following eyelids. Further treatment should be directed to the hospital depending on the degree of entropion. Five, eye fatigue blink eye fatigue, such as refractive error, especially farsightedness, myopia, astigmatism caused by uncorrected eye visual fatigue and caused. This is a protective reflex, through the non-stop blinking can go to adjust the curvature of the eye, so that visual clarity. This situation should be properly arranged for the child’s school life, reduce the use of eyes, if necessary, optometry and glasses. Some children have a history of blinking due to one of the above mentioned causes, but after the cause is removed through treatment, they still retain the habit of blinking. Some children may imitate other people’s blinking habits, resulting in frequent blinking, which parents should remind their children of and help them control. VII. Temporary tic disorder This condition is generally nothing to worry about, as 4%-24% of school-age children will have this condition. The involuntary twitching of the eye muscles is related to stimulation and stress. It usually subsides on its own, over a period of about 1 month. If the child has this condition for more than 1 year and there is a change in personality, it is medically called hyperactive stigmatization syndrome in children and should be promptly seen by a pediatrician. In conclusion, if parents find that their child is blinking frequently, they should take their child to the hospital promptly if they cannot go to judge for themselves. In terms of diet, there are some foods that you should usually give your child more of: carotene, vitamin B1, vitamin B2, B6, and vitamin C.
