The causes and prevention of myopia in students, myopia has become an inescapable topic in our life now, the number of myopia is increasing, the age of myopia is also showing a younger age, more and more elementary school students can appear myopia problems. The lack of attention to eye health in daily life is the main reason for the increasing number of myopia in elementary school students. First of all, elementary school students are always curious about new things, so it is easy to stare at things of interest for a long time when looking at things. If it is something with strong colors and a fixed light source, it will stimulate the child’s retina for a long time, which will cause serious eye fatigue and make the ciliary body of the eye, which regulates refraction, overly tense, and the adjustment ability decreases, resulting in myopia. Secondly, when reading and looking at things without paying attention to distance control, the distance is too far or too close, which may lead to fatigue of the eye adjustment focal system, which will lead to vision loss in a short period of time. This stage is what we often call pseudomyopia, but if you don’t rest enough, over time, you will turn pseudomyopia into real myopia. In addition, the brightness of the light when using the eyes is also one of the causes of myopia in children, too bright or too dark light is not conducive to the health of children’s eyes. The eye is like a delicate camera, the camera can adjust the intensity of light through the lens, while the eye is adjusted by the size of the open pupil, too strong or too weak light will make the eye fatigue increased, increasing the possibility of myopia. In response to the above-mentioned causes of myopia in elementary school students, we would like to remind parents that they should learn and master the correct way to use their eyes, and only if they understand it, they can supervise and educate their children in their daily lives and studies. Once you find that your child has symptoms such as frequent eye rubbing, squinting, and tilting the head to look at things, you should go to a regular hospital for an examination as soon as possible.
