5, a high school student walks on the phone while he walks. Our reporter Qiu Zhiqiang, our reporter Zhao Wei Intern Ren Liyuan, June 6th is "National Eye Care Day". Recently, the reporter visited the ophthalmology outpatient of many hospitals in the provincial capital, and found that the number of teenage myopia continued to increase, especially after the popularization of digital products such as tablet computers and smartphones. Glasses. Doctors therefore remind teenagers that the use of digital products should be reduced. Children under the age of 3 should be far removed from digital products such as tablets. The tablet computer is the main cause of children's myopia in the kindergarten near the mountain road (the pseudonym) is a "flat control", this year is only 5 years old, but the eyes have been nearsighted 300 degrees. Bright mother introduced, bright from 3 years old, the first thing to go home every day is to open a tablet computer, most like to play "cut fruit", "angry birds" and other small games. Not long ago, when I looked at something far away, I had to squint. The doctor found that he had become myopia with a degree of 300 degrees. tablet computers, smart phones and other factors have become the main factors affecting the eyesight of adolescents and children. In a number of eyeglasses near the Cultural East Road, the shop assistants call a large number of primary and secondary school students. "The children who come to mirror the mirror are mostly due to long exposure to electronic products, such as computers, tablets, mobile phones, and so on, the degree is very high, some are more than 400 degrees". It is also common for adults to buy digital products for children at the cyber mall of Shan Da Road.
interview, the reporter learned that there are some young parents, children cry, often the cell phone, tablet computer and other children to play games, unwittingly, children have become "digital product control", day and night playing, hurt the eyes.
playing digital products, the youngsters are getting younger and younger, and many of them have developed bad habits. With the promotion of smart phones, watching movies, micro-blog, chat, e-books and so on can be completed on mobile phones, many young people are hand in hand. Reporters on bus sites, buses, campus doors and other different occasions, you can see teenagers holding a mobile phone to brush micro-blog, chat and so on.
on occasions where some friends meet, many people are also used to playing with their cell phones. In addition, the emergence and emergence of games, computer games, mobile games, so that many children, especially the early and high school children, is easy to indulge in it, due to lack of restraint, excessive use of eyes to cause myopia. LCD touch screens also hurt the eyes. "Because of the lack of self-control and neglect of parents, modern electronic video products have become the culprit of" small eyeglasses ". Yang Shaoyuan, director of ophthalmology clinic of Qianfo Hill Hospital of Shandong Province, said that myopia is influenced not only by genetic genes but also by environmental factors. For teenagers who are in the growing stage, too much contact with digital products is more likely to induce myopia.
in an interview, some teenagers who are very fond of using tablet computers think that tablets do not hurt their eyes with a LCD touch screen, and there is no problem in how to play.
"in fact, this idea is wrong." Yang Shaoyuan said myopia is caused by excessive eye contact, excessive fatigue, decreased eye accommodation, and ciliary muscle spasticity. The general use of a tablet is only more than 30 centimetres, children use up, eyes too focused, forget the blink of eye, will affect the eye lubrication system work, so that the intima protection eye surface tissue lubrication can not work normally. "Coupled with the immature development of the visual system of children, it is very easy to produce visual fatigue by controlling the closed muscles and pupil contraction ability." Experts also said that the tablet computer LED background light will make the tablet higher brightness, the pupil will continue to shrink in order to adapt to the change of the light source, and the adjustment of the pupil of the ciliary muscle will always be in a high tension, resulting in excessive lens buckling of the eyes, thus increasing the refractive index of the eyes, a long time, which will lead to the ciliary. Spasm of the muscle of the muscle that causes regulatory myopia.
in addition, children's language ability is limited, unable to express their eyes in a dry state, even dry eyes are not aware of what it feels like. In this way, many parents easily overlook the harm of tablet computers to children's eyesight. In addition, the radiation produced by electronic products is also harmful to children's health. Playing with electronic products for a long time can easily destroy traditional interpersonal relationships, which will be less humane and may become lonely and autistic. The myopia rate of urban children is higher than the Rural Ministry of education and the latest investigation by the Ministry of health. At present, there are more than 400 million myopia patients in our country, the incidence of myopia is 33.3%, the myopia rate of primary school students is over 25%, the myopia rate of junior high school students reaches 70%, the myopia rate of high school students is 85%, and the world is the first in the world, among them the youngsters are the first in the world. Myopia is "heavy disaster area".
Yang Tao, physician of the Concordia eye center of the Eighth People's Hospital of Ji'nan, said that there are far more teenagers in the city than those in the countryside. "People in cities are more familiar with electronic products, especially in children and adolescents. Staring at electronic products for a long distance, tired eyes can not rest, and easily lead to myopia. In the countryside, the vision is wide and the distance is easy to see. The city is full of tall buildings, blocking the line of sight and not looking far ahead. Experts say, the medical field also began to popular a computer video terminal syndrome, that is, long time use of computers such as electronic products, eye fatigue, eye dry, foreign body feeling, more secretions, blurred sight and other symptoms. These occupational diseases originally belonged to white-collar workers are now beginning to invade children. Children with eye swelling and dry eye are not uncommon.
"to protect your eyesight, you should start from now." Yang Tao suggested that teenagers should minimize the use of electronic products such as tablets, cell phones and so on, with no more than 1 hours a day. Especially for children with visual development stage, parents should strengthen supervision. Children under the age of 3 should stay away from digital products such as tablet computers. In addition, at weekends, parents should take their children to the countryside to broaden their horizons. We should also pay attention to visual examination and prevent pseudmyopia from turning into true myopia.
