Should I let my child watch TV? Should I let my child play with the phone? I believe that this is a very contradictory question in front of all parents. As a channel for acquiring knowledge outside of books, TV and cell phones can satisfy children’s desire for knowledge. In a study conducted by a Canadian scholar, they chose a remote town without TV and an ordinary town with TV to compare their children’s creativity and reading test scores, which were much lower than those in the town with TV. small towns. So, watching television itself is largely a developmental stimulus for children themselves. But it is well known that TV and cell phones are not good for children’s eyes and they are afraid of hurting them, so are all children watching TV and playing with cell phones harmful to their eyes? Nowadays, almost all parents know that TV, cell phones and computers are not good for children’s eyes, so regardless of the condition of their children’s eyes, they will restrict watching TV, playing with cell phones and computers in a one-size-fits-all way. In fact, we should differentiate whether children can watch TV or not. Children who are myopic or mildly farsighted should not watch TV, play with cell phones or computers, as this may lead to further aggravation of myopia or accelerate the formation of myopia. For this group of children, I have reminded the parents during the hospital visit. However, for amblyopic children with high hyperopia, not only can they watch TV, but they are encouraged to watch more TV (as long as it does not interfere with their studies). Television viewing is not bad for hyperopic amblyopia, but rather beneficial. This is because amblyopia requires light to stimulate the eyes so that the fundus of the eye develops gradually, thus improving vision. In addition, because the child’s hyperopia is high, watching TV just has the effect of accelerating the farsightedness orthophoria, which can make the farsightedness reduce faster. Many parents ask what level of farsightedness is allowed to watch TV, play with computers and cell phones? The ability to watch TV, play computer and cell phone is divided into three categories: prohibited, appropriate and encouraged. Those with farsightedness below three hundred degrees and myopia are not allowed to watch TV, those with farsightedness between three hundred and fifty and five hundred degrees can watch TV appropriately, and those with farsightedness above five hundred degrees should be encouraged to watch more TV and play with cell phones and computers. As for how to play to improve vision faster, we will talk more about that in a future article. Why should children with low farsightedness watch TV and computers moderately? Because the child’s farsightedness is no longer very high, to consider the farsightedness will likely form myopia after the retreat, retaining a slight farsightedness is very valuable to the child’s eyes.
