Wearing glasses is a correction of vision, mainly to see clearly, it does not deepen the prescription, but it also does not stop the progression of the prescription. The key is to get the right glasses to reduce the pressure on the eye so that your child’s nearsightedness stays the same for a long time. Parents, do you know the reason why your child’s myopia is getting deeper? The reasons why children’s myopia is getting deeper are as follows: 1. Too little vision in the city, where people’s vision is within 5 meters most of the time, you can’t explain to your child what the horizon is because you can’t see it! It is because the city vision is not open, the lack of the environment that can provide children with extreme vision, do not need to use far-sighted, so his far-sightedness will become weaker and weaker. 2, improper light intensity In fact, the lights of children reading and writing now are not too dark, but too bright! Too strong light will make the child’s eyes easily feel tired. What children need is soft light, and to ensure that the light comes from the left front of the child. So, adjust the light to soft at night when the child is reading or writing. 3, beautiful books can hurt the eyes However, these beautiful books may also hurt the child’s eyes it. Copperplate paper is too strong reflective, especially at night, feel especially obvious, straight shaking eyes. This shiny light is medically called glare, which makes what you want to see more unclear, the eyes more easily tired. 4, too little outdoor activities Nowadays, the living space is too small, most of the time children are indoors, a lot of close eye time, and children’s eyes adaptability is very strong, it will adjust to adapt to the close distance. And, 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 over-exhausted. 5, glasses are too casual to the ciliary muscle dilated optometry is to let the child’s eye ciliary muscle in a state of complete relaxation, so as to find out the cause of the child’s poor vision, whether it is true myopia or pseudomyopia, is farsighted or astigmatism. 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. As a result, the child’s myopia will progress to a deeper degree. Some children have pseudomyopia, which can be restored to normal with functional exercises, but parents go directly to the optician without dilating their pupils and give them glasses to wear, so that the eye slowly changes during the long-term adaptation process, which can become true myopia or make the child’s myopia deeper and deeper.
