Prevent myopia and let children go outdoors more

Abstract: Children’s long-time and close use of electronic products is indeed easy to cause eye fatigue and myopia. “When people stare at smart phones, iPads and other electronic products, the pupil size will constantly change to adapt to the change of light source. When they look at the screen closely for a long time, the ciliary muscles will always remain tense.

nearly 40% of children play mobile phones and iPads for more than two hours every day Now it is a screen reading era. Smart phones and iPads have been widely used and are sought after by children. In most families, due to busy work and doting on children, parents will habitually use iPads to send their children. In restaurants, subways and other public places, children can be seen playing games with electronic products. Many children have become “low vision people”. According to the family doctor’s online “children’s eye health survey”, It is found that nearly 40% (39.51%) of children play mobile phones and iPads for more than two hours every day, 34.56% of children have different degrees of myopia, and 18.67% have astigmatism.

Children play iPad every day and their eyesight drops. Will they get myopia? Children’s long-term and close use of electronic products is indeed easy to cause eye fatigue and myopia. “When people stare at smart phones, iPads and other electronic products, the pupil size will constantly change to adapt to the change of light source. When they stare at the screen for a long time, the ciliary muscle will always maintain a tense state. Due to the continuous flashing of the electronic screen, especially when playing mobile games, their attention is highly concentrated, the ciliary muscle must move frequently, and can not be relaxed for a long time, which can lead to over time Ciliary muscle spasm, so that the lens continues to become convex, resulting in regulatory myopia. If it is not prevented and treated in time, it will soon evolve into true myopia. ”

after the winter and summer holidays every year, many children’s myopia will deepen a lot, and some will deepen 100 degrees in a holiday. The reason is that children play with mobile phones and iPads frequently during the holidays, resulting in eye fatigue and poor adjustment ability. At this time, the degree will rise very quickly.

however, in addition to myopia, the common causes of children’s low vision include hyperopia, astigmatism, amblyopia, and some even strabismus. If the child’s vision is still not normal after wearing glasses, There may be amblyopia (ametropia and different degrees of refraction in both eyes). There is a kind of monocular amblyopia, which is born and cannot be detected by children. It is often difficult to be found. It is usually found only during eye screening.

If children are found to have some abnormal behaviors, attention should be paid, such as squinting at TV, Unconsciously leaning forward when watching TV, and astigmatism children will tilt their heads. These are signs of poor vision. Parents should take their children to the hospital for eye examination as soon as possible to find out the causes. In addition, parents are advised to establish a refractive development file for their children. The specific method is to go to the hospital ophthalmology for eye examination every 6 months from the child’s age of 3, and record the refractive power, eye axis length, corneal curvature radius, intraocular pressure and other values. There are three advantages in doing so –

and

. First, it can detect abnormal refraction early, such as high hyperopia, myopia, astigmatism and amblyopia; Second, it can find out whether the child has eye diseases as soon as possible; Three can screen out the “blank” of myopia among children with normal vision. For example, most 8-year-old children have hyperopia below 125-150 degrees, and their vision can be 1.0. If the refractive state of an 8-year-old child is 75 degree hyperopia or emmetropia, it shows that the child has a high probability of becoming myopia in the future. Intervention measures must be taken in time to prevent the occurrence of myopia.

children’s myopia lenses need to be replaced frequently. The

and

children are in the development stage, the eye size is still changing, and the plasticity is very strong. If they intervene too early before the degree is not stable, there will be residual degrees. For example, the child’s degree is 200 degrees this year and may be 250 degrees next year; If it is hyperopia, it is 300 degrees this year and may reach 250 degrees next year. Before the degree is not stable, children mainly use frame glasses, which is not suitable for laser and intraocular lens implantation. After

and

found that children were short-sighted, nearly 80% of parents were unwilling to let their children wear glasses all the time. They were worried that their children would not be able to take them off once they put them on, so they were keen to seek methods for their children, such as massage, traditional Chinese medicine acupuncture, therapeutic instrument training, eye exercises, health drugs and so on. In fact, there is no way to really reverse or control the occurrence and development of children’s myopia. Because the occurrence and development of myopia have genetic factors and a large number of acquired environmental factors, myopia in children and adolescents will still show a deepening trend after wearing glasses, which is not caused by wearing glasses.

in addition, children’s eye development goes through the process of hyperopia → emmetropia → myopia, and the diopter will change to some extent every year. Therefore, doctors will do optometry in the reexamination of children, and change lenses or glasses according to the change of children’s diopter, which will be adjusted according to the development of the eye.

put down the iPad and go wild outdoors.

and

should first avoid watching TV and playing mobile games at close range for a long time; More outdoor activities; Lighting with sufficient brightness; In terms of diet, we should eat more vegetables and fruits containing vitamins and not partial food; If reading and homework do not last for more than one hour, pay attention to interval rest.

research shows that the myopia rate of children who spend 3 hours outdoors every day is only 0.8%, that of children who spend 1 hour outdoors is 3%, and that of children who spend only half an hour outdoors every day is 24%. Therefore, experiments have proved that 3 hours of outdoor activities a day can make school-age children almost not myopia. First of all, during outdoor activities, children’s eyes and body contact with sunlight can promote the human body to secrete more dopamine, effectively inhibit the growth of eyeballs, so as to inhibit the occurrence and development of myopia. Secondly, the light intensity of outdoor sports is high, which reduces the pupil and deepens the depth of field, so as to increase the clarity of visual objects and delay the development of myopia. In addition, outdoor activities will look more into the distance to relax the eyes, which is precisely the best way to protect children’s eyesight.
