Myopia: Mild myopia can be considered by wearing prescription glasses during class and study. Moderate to high myopia requires daily use of glasses. The glasses are only used to correct myopia and achieve normal vision, but cannot prevent and control the development of myopia. The best way to prevent and control the development of myopia is to increase outdoor activities, let the eyes rest more, balance the diet, and improve the visual environment.

Myopia is caused by genetic and environmental factors. Prolonged use of the eye to see things close to it can promote the development of myopia. It is necessary to improve the visual environment and allow the eyes to rest more.

After all, there are many habits that can harm the eyes. A good eye habit should follow the "20-20-20" principle, which means using the eyes for 20 minutes, staring at a distance of 20 meters, and allowing the eyes to rest for at least 20 seconds. Children and adolescents need to protect their eyes and engage in more outdoor activities. Engaging in outdoor activities for more than 2 hours a day during the day can help control the progression of myopia.

Strictly speaking, myopia cannot be completely cured, but for adult myopia patients, laser surgery can be considered. By changing the corneal refractive power, the effect of changing the light incident on the eyeball can be achieved.

For underage children, the development of myopia can be controlled by wearing corneal shaping lenses, but this is not a one-time solution and cannot be eradicated. But corneal shaping lenses are currently an effective method to delay the development of myopia, and the effect is still good.
