Presbyopic glasses can not prevent myopia, there is absolutely no scientific basis. Presbyopic glasses are mainly designed to improve the near vision of middle-aged and elderly people. After putting on presbyopic glasses, near vision can be restored to normal, and it will be clearer when reading at close range, which has nothing to do with myopia at all. Myopia is due to the refractive power of the eyes exceeds the normal range, so that is why the loss of distance vision, that is, when looking at distant places is blurred. In order to prevent the appearance of myopia, it is necessary to start with the cause. There are usually two causes of myopia: the first is the congenital genetic factors; the second is the acquired bad eye habits. For congenital genetic factors are beyond human control, so in order to prevent the occurrence of myopia, it is important to maintain reasonable eye habits. The use of presbyopic glasses to relax the adjustment of myopia is one of the working principles of myopia regression lenses, but at the same time to consider the individual adjustment power and vision near the situation of the two eyes together, need to personalize the fitting and customization, not simply use presbyopic glasses instead.
