Is vision training really effective for treating myopia?

Generally, vision training can be effective for pseudo-myopia, but may not be effective for true myopia. The specific analysis is as follows:

Pseudo-myopia is mainly caused by excessive eye use leading to ciliary muscle spasm, which in turn causes eye fatigue and changes in the lens focus, resulting in temporary vision decline. In such cases, vision training can be effective. Training methods such as distant gazing or fogging techniques can help relieve ciliary muscle spasm, improve pseudo-myopia, relax the eyes, and gradually restore vision.

For true myopia, the effectiveness of training may be limited. True myopia results from structural changes in the eye, such as elongation of the axial length or alterations in the refractive power of the cornea or lens—organic factors that are typically irreversible. Vision training alone cannot fully restore vision because it cannot reverse the elongated axial length or restore normal refractive structure. However, vision training may still help improve the eye's focusing ability and alleviate visual fatigue to some extent.

In daily life, it is important to develop good habits, reduce eye strain and screen time, and engage in appropriate physical exercise such as jogging or hiking, which contributes to overall health.
