Seeing too much up close In the city, where people see within 5 meters most of the time, you can’t even explain to your child what the horizon is because it’s not visible! It is because the view is not open in the city and there is a lack of environment that can provide the child with extreme vision without the need to use distance vision, so his distance vision will become weaker and weaker. Too little time for outdoor activities Nowadays, the living space is too small, children are mostly indoors, and there are many times when they use their eyes at close range, and children’s eyes are very adaptable, and it will adjust itself to adapt to this close distance. Moreover, more time in the house, watching TV, playing computer opportunities also increased, if you do not pay attention to the distance, posture, it is easy to make the eyes overworked. In the outdoors, objects are no closer, but also farther than in the house. Some studies have proved that children who often play outdoors are less likely to suffer from myopia than children who do not go out often. Inappropriate light intensity “Is the light bright enough? I’m worried that the lights are too dim and will affect my child’s vision.” That’s what we generally think. In fact, ophthalmologists believe that the lights that children use to read and write are not too dim, but too bright! Too much light can make a child’s eyes easily feel fatigued. What children need is soft light, and make sure that the light comes from the child’s left front. So, at night when your child is reading or writing, choose a lamp that can adjust the brightness to soft. The reason for your child’s poor eyesight, whether it is true myopia or pseudomyopia, farsightedness or astigmatism, can be found out by having the ciliary muscle completely relaxed. Conventional astigmatism can take up to a week to restore free reading. Parents who are in a hurry often opt for a rapid dilator. However, when the pupil is quickly dilated, the child’s ciliary muscle is only in a state of insufficient paralysis, not completely relaxed. The test results obtained at this time are not accurate, and there is a risk that the child will be given myopic glasses with a higher prescription than the actual prescription. In this way, the child’s myopia will develop to a deeper degree. Book paper, printing is too “delicate” More and more exquisite printing, more and more sophisticated paper, so that children’s books are increasingly ornamental. However, these beautiful books may also harm the eyes of children. Copperplate paper is too reflective, especially at night, it feels especially obvious, straight shaking eyes. This dazzling light is medically called glare, which makes what you want to see more unclear, and eye fatigue more easily.
