At the beginning of school season, children are myopic and sit in the front row? Ophthalmologist’s warning is a misunderstanding

Abstract: in the city, people’s line of sight is less than 5 meters most of the time. It is precisely because the vision in the city is not open and there is no environment that can provide children with a panoramic view. There is no need to use hyperopia, so his hyperopia function will be weaker and weaker. Moreover, more time in the house will increase the opportunities to watch TV and play computer. If you don’t pay attention to distance and posture, It’s easy to fatigue your eyes. In the

school season, many schools have added many “little glasses”. Some parents are worried that their children can’t see clearly or the degree is deepened. They specially ask the head teacher to adjust their children’s seats to the front row, so as to relax their children’s eyes and see clearly in class. But is it scientific to let myopic children sit in the front row from the perspective of eye protection? He Tiangeng, deputy chief ophthalmologist of Tianjin Medical University General Hospital, said that if a child’s vision declines, it is very harmful to the eyes to transfer the child to the front row.

and

experts say that myopia occurs constantly, and the root cause of its development is to look close for a long time. Seeing close has two meanings: on the one hand, it refers to using eyes close, such as reading, homework, painting, origami, jigsaw puzzle, etc; On the other hand, it refers to staying in the near visual environment for a long time (less than 5m belongs to the near environment). For the light reflected by objects 5 to 6 meters away from the eyes, the eyes can form a clear image on the retina without adjustment. At this time, the nerves and muscles regulating the eyes are relaxed, but if you want to see objects within 5 meters, the muscles regulating the eyes must contract in varying degrees. Therefore, the closer the objects seen by the eyes, the higher the degree of contraction, The more tired your eyes are. Over time, it is easy to cause myopia. The younger the child is, the less the eyeball is developed, and the more he can’t stand using his eyes at close range. Therefore, parents should no longer superstitious about the front row. Myopic students should not sit in the front row. Sitting 5 to 6 meters away from the blackboard is the best position.

at present, more and more children are nearsighted, which is directly related to overuse of eyes to a great extent. In the city, people’s sight is less than 5 meters most of the time. It is precisely because the vision in the city is not open and there is no environment that can provide children with a panoramic view. There is no need to use remote vision, so his remote vision function will become weaker and weaker. Moreover, more time in the house, more opportunities to watch TV and play computer. If you don’t pay attention to distance and posture, It’s easy to fatigue your eyes. Director he Tiangeng of

introduced that for myopia, if no measures or improper measures are taken, myopia will increase by 75 to 150 degrees every year. More than 60% of students will develop into high myopia of more than 600 degrees when they graduate from high school, and even produce fundus complications, affecting eye health and major choice of college entrance examination. When it is found that the child cannot see clearly, parents should take the child to a regular hospital and find a professional ophthalmologist to determine whether the child’s myopia is true myopia or false myopia. If a nearsighted child has glasses but still can’t see the blackboard clearly, it indicates that there is a problem with the child’s refractive correction, or the child’s myopia has increased again. Scientific control of myopia should not only develop scientific eye habits, but also regularly carry out comprehensive visual examination, and formulate scientific eye care plans according to the examination results to effectively control the development of myopia.
