Eye axis abnormalities caused by close eye use such as reading, playing computer games, and looking at cell phones have become the most important cause of myopia in students, and eye axis abnormalities are due to children not adopting the correct posture when reading on the one hand, and the age of starting to read on the other. Therefore, before the age of 5, do not give children to read books with a lot of text, you can only read some large picture books, and do not let the child too early access to some electronic products such as computers and cell phones. In addition, parents should also be careful not to choose smooth, easily reflective paper books when buying reading materials for their children, but should buy reading materials with slightly yellowed paper. When reading or writing for half an hour to an hour, you should take a 10-minute break, look away, close your eyes and rest or do eye exercises. Do not watch TV, play computer, play video games, look at cell phones for a long time, and pay attention to keep your eyes at a certain distance from the fluorescent screen. Doing homework on the table will increase the burden on the eyes, cause visual fatigue, and easily cause or deepen myopia. Reading and writing should maintain the correct posture (a foot, a fist, an inch) that the eyes from the book a foot (33 cm); chest from the edge of the table a fist (10 cm); hand from the pen tip an inch (3.3 cm). When children read and study, parents should choose 35 to 40 watt incandescent lamps for children as study lamps. Because of the existence of eye protection lamps and energy-saving lamps “strobe”, not to play the purpose of eye protection. The lamp is placed in the upper left corner of the desk. This is because the incandescent light is softer and easier for the eyes to adapt to, preventing eye fatigue caused by too much light or too dark. Make sure that you get enough sleep and keep your child outdoors, so that he or she can keep his or her gaze beyond 5 meters, and actively participate in physical exercise to improve physical fitness. Every day, insist on doing eye exercises, and insist on doing them carefully and often, with accurate movements and acupuncture points. Pay attention to balanced nutrition, eat more fresh vegetables and fruits, don’t be partial to food, don’t drink or drink less carbonated drinks. Regularly make vision checkups and treat any problems in time. Grasp prevention, early and young, and take preventive measures from kindergarten to protect the normal development of the eyes.
