According to a recent report by Reuters, breast milk contains a substance called “DHA”. It is the main element that improves the early visual development of infants, allowing the eye to grow more regularly, thus reducing the chance of myopia or reducing the degree of myopia. DHA also plays a very important role in the development of photoreceptor cells in the retina, which is also related to the possibility of myopia. And a study recently published by Singaporean researchers showed that children who were breastfed were about 50 percent less likely to develop myopia later in life than those who were not breastfed. During the study, researchers medically examined 797 children in Singapore between the ages of 10 and 12 and also asked them a series of questions, including how many books they read each week. The results of the study showed that even after taking into account a number of other factors, breastfed children were still 60 percent as likely to develop myopia as non-breastfed children. According to the students, the root cause of the development of simple myopia is caused by students looking too close. Therefore, limiting excessive near vision is fundamental to the prevention and treatment of myopia! Training to look at distance is an aid to prevent and control myopia, and the medical approach is an approach with side effects in special cases or special need situations. Look close can use the tools to control the distance to help students solve the problem of sitting and sight distance, such as adjusting sitting and distance tools training sitting reading and writing distance looking glasses. Look far can do polar vision, distance recognition, etc. Various outdoor sports, such as kite flying, soccer, etc. The occurrence of myopia is related to prolonged or long-term close reading. When reading at close range, the ciliary muscle, which regulates vision, is often in spasm, and only when looking far away does the ciliary muscle relax naturally and the spasm is relieved. So children should be encouraged to participate in more outdoor activities!
