I believe that many friends want their children to have a pair of bright and beautiful eyes, do not want their children to wear small glasses and join the ranks of myopia. So many parents pay close attention to protecting and correcting their children’s eye habits as they grow up, but whether the measures taken are correct or not, here’s an analysis with you: One: preschool (before the age of 7) does not allow children to watch TV, computers and cell phones can prevent myopia. On this point, I can only partially agree. First of all, a person’s vision development from birth to 7 years old basic development and maturity (in layman’s terms, just like long height, from birth to about 20 years old will not grow again), such as 3 years old to check the visual acuity table 0, 3, 5 years old to 0, 6, 7 years old to 1, 0, in this development process to promote the development of vision factors are the following: 1, adequate nutrition, mainly vitamin class, to put it bluntly is to eat more vegetarian dishes (eat more vegetables than a variety of vitamin pills much better); 2, enough light stimulation, how to understand this, or take the long body for example, want to grow taller, in addition to eating well, eat more, more physical exercise is essential, the same reason, the stimulation of light is the development of vision “physical exercise”, the white The same reason, the stimulation of light is the development of vision “physical exercise”, so the white is to see more things, and the light of electronic products such as television is conducive to vision development, as long as you keep enough distance, there will not be any problems. 3, if you do not get enough light stimulation and nutrition during the development period, vision to maturity may not reach normal levels (, for example, elementary school vision, both eyes 0, 8 or 0, 6, in the absence of any eye disease and refractive error, this is called amblyopia). And it is difficult to return to the normal level with subsequent treatment. To sum up, for children’s eye care, do not need to see television, computers, cell phones and other electronic products as a flood of beasts, as long as the viewing distance is good, appropriate viewing is conducive to vision development.
