Children always sit in front of the is not necessarily a good thing

China's traditional Chinese medicine reported

        2011 jiangsu province in student physical health monitoring results released recently. The data shows, jiangsu province DiLingHua trend obviously students myopia, 7 years old children one third of myopia. The results caused nanjing an eye specialist attention, experts think, many in children of eyesight reduction factor neglected, it is necessary to let you know, cause attention.

        Nanjing medicine hospital to establish refractive files in the eye of the three to five year 600 school-age children examination found that, in addition to myopia small more patients outside, in children myopia, and a strange phenomenon, close to 60% of the child is much stronger than his right eye left deep. That is, 10 nearsightedness, 6 high degree right eye. This phenomenon has created, director of the XiaChengZhi of great interest, he further research found that for small age myopia, previously believed "study pressure big, watch TV, play games more" cannot fully explain, still holding the pen and the correct posture or not has the very big relations.

        XiaChengZhi said that holding the pen to write the correct posture, should be the thumb and index finger knead a pen, holding pens fulcrum fell on the first day the middle finger to thumb side. According to the principle of physics, the fulcrum to the tip of a distance of about 3 cm, is relative, thumb and forefinger and pen the contact point to pivot distance is about 0.5 centimeters is power arm. Relative/power arm = 6 times, in this sense, the right to hold pen should be easily leverage for children is a hard life.

        XiaChengZhi further explained that children with if you hold the pen to write with the age or to force too small, in order to remedy this, the children will not hold pen with the correct posture to substitute, the specific performance holding pens on the fulcrum (reduce the relative) and near the bag with thumb root around holding the pen (increase power). This kind of holding pens pose once forms, it can make children to see the tip, the head natural left, and his eyes distance closer to paper, for myopia buried the hidden trouble. XiaChengZhi will call it a "myopia is writing style," and there are 7 into children in using this method of holding the pen.

        XiaChengZhi special remind, for school-age children, in addition to holding the pen posture, influence myopia have another factor is that seat. If short always sat in the first row, second row, long-term close face the blackboard, but easy to form myopia. And if in front of the children slight myopia, but due to sit together, leading to deepen degree goes step by step. From this perspective, if your child is always sit in the front row, in fact is not necessarily a good thing. XiaChengZhi director suggests, students of the row seat scientific method should be adjusted according to the group, that is, to sit in a group of tall, medium height sit a group, and short on a group, and then will QianHouPai switch, thereby preventing myopia.
