During the summer and winter holidays, many more parents than usual take their children to the hospital for eye examinations. Some of them just want to check whether their children’s eyesight has decreased, after all, eyesight is crucial for their studies. Some children who have poor eyesight want to check whether the refractive error of their eyes has deepened over the semester, whether they need to replace their glasses lenses, etc. Parents often encounter such parents, know that their children’s vision is already very poor, can not read the teacher’s board in class, after the doctor’s examination has been true myopia recommended refractive correction, that is, wear glasses, some parents will hesitate whether the glasses, some flatly refused to give the child glasses, think that the child is still young, wear glasses will lead to myopia deepening, very worried. On the other hand, as an ophthalmologist, I feel a great responsibility. Doctors have an obligation to spread the daily knowledge of ophthalmology to schools and communities, and to answer the questions of those who need help from doctors. Once the doctor examines the true myopia (under 12 years old to confirm whether the true needs to dilate the pupil optometry), and the blurred vision has affected the child’s study in class, I will recommend glasses, if you do not want to wear glasses, and myopia deepening faster, will recommend wearing corneal plastic lens at night, then the daytime vision back to normal will not need to wear glasses. The basic focus of both treatments is the same, which is to correct the refractive error in the eye, so that the vision returns to normal and reaches the pre-myopia level. Of course, myopia is a dynamic process, especially at school age, the degree is still unstable, daily life, reading and learning to remember to use eye hygiene, avoid improper posture, prolonged close eye use, otherwise the degree will still deepen. Why do you need to wear glasses once you have true myopia? The human eye is like a camera, myopia, the outside light will not converge to the bottom of the camera, naturally, the outside objects projected into the camera is a blurred image. We all know a common sense, is to care for children do not read books in poor light, then myopia without glasses, and dim place to read is the same. Long ago, there are such animal science experiments, after hatching that blindfolded chicken, later will gradually develop myopia. It is also concluded that the blurred state of vision will lead to myopia deepening. Although this is only one of the factors of myopia deepening. So for wearing glasses will lead to myopia deepening or not? For sure, a proper pair of glasses will definitely help the eyes as long as the regular optometry is done. There are genetic and environmental factors that contribute to the deepening of myopia, but wearing glasses is not a factor in the deepening of myopia. However, it is important to emphasize that some children wear glasses incorrectly and do not care for their lenses, which requires parental assistance. It is often found that many children do not wear glasses correctly and droop on the bridge of the nose, some glasses frames are uneven and the lenses are already rough, so if these phenomena are not corrected in time, the prescription will naturally deepen over time.
