The answer is not. Because myopia occurred largely due to the eye before and after the shaft is too long, followed by a strong eye refractive power. After a person is more than 40 years old, these conditions will be developed in the opposite direction. Lens hardening, less elastic, the ciliary muscle contraction and reduced ability to to Erzhi adjust the loss, eye front and rear axles shorter, and the near point distalization presbyopia. When one comes to 60-year-old, the condition will fixed. Therefore, the degree of myopia is no longer increasing. So people have a 60 sixtieth (vision) to the juvenile argument. In a conclusion, you don't need to worry about your myopia become worse when your are older.
