How does myopia develop? Myopia is caused by two main factors: genetic factors and environmental factors. If both parents or one parent is myopic, their children have a high chance of developing myopia. Moreover, due to environmental factors, the age of onset of myopia in children is usually earlier than that of their parents, and some preschoolers are found to be myopic. In addition, premature and prolonged television viewing, computer games, and incorrect eye time, distance, light, and posture can all cause myopia. How is myopia treated in children? Parents should not blindly believe in the propaganda of informal medical institutions and try to replace glasses with various treatments, which will only backfire and further increase the degree of myopia. The safest and most effective way to treat myopia in children is still to wear orbital frame glasses. You should always have your pupils dilated and examined before getting glasses. Will myopia get deeper with glasses? Once myopia occurs, there will be irreversible progression. Whether or not you wear glasses, as you grow older, the front and back of the eye grows and the myopia deepens. On the contrary, if you don’t wear glasses for myopia, your eyes will get tired easily and your myopia will deepen faster. Can glasses be worn and removed at the same time? The correct approach is to not wear glasses when reading or writing with mild to moderate myopia, but to wear them when looking at a distance. If you have severe myopia, you should always wear glasses. Can myopia in children be treated with laser? No, because children under the age of 18 are still developing and their myopia is unstable. Laser surgery should not be performed until they are adults and their myopia has stabilized for 1-2 years.
