some parents worry that their children can’t see clearly or the degree is deepened after their children have myopia. They specially take care of the head teacher and teachers to adjust their children’s seats to the front row, so as to relax their children’s glasses and see clearly in class, but is this science?
experts warn that arranging myopia students in the front row is very harmful to the eyes. First of all, you should understand that myopia occurs constantly, and the root of its development is to see close. 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 one hand, it means staying in the near environment for a long time (if it is less than 5m, it belongs to the near environment). For the light reflected by objects 5m-6m 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 5m, the muscles regulating the eyes must contract to varying degrees. Therefore, what the eyes see The closer the object, the higher the degree of contraction, and the more tired the eyes are. Therefore, myopia students should not sit in the front row. Sitting 5-6 meters away from the blackboard is the best position. In the face of more and more children with myopia, myopia is directly related to overuse to a great extent. Children’s eyeballs are not well developed. The smaller the child is, the more he can’t stand close eye use. Excessive eye use for a long time will increase the burden of eyeballs. For every 1 mm increase in eye length, the degree of myopia increases by 300 degrees. In the city, people’s line of sight is within 5 meters most of the time. You can’t explain to your children what the horizon is, because you can’t see it at all! It is precisely because the vision in the city is not open, the environment that can provide children with a panoramic view is lacking, and there is no need to use hyperopia. Therefore, his hyperopia function will become weaker and weaker. Now the living space is too narrow. Children spend most of their time indoors and use their eyes at close range. Children’s eyes are very adaptable. They will adjust themselves to adapt to this close range. 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 make your eyes too tired. No matter how close an object is outside, it must be farther than inside. Studies have shown that children who often exercise outdoors suffer from myopia less than children who don’t go out often.
