Patient's question:
I had pretty good eyesight a few years ago, but recently, due to excessive eye strain and long-term fatigue, I developed nearsightedness. I don't know if moving the eyes around can cure nearsightedness.Doctor's answer:
Useless. Eye rotation depends on the external muscles of the eye. Eyeglasses adjust focus through the ciliary muscles inside the lens. In normal vision, when looking at distant objects (such as stars, where light is almost parallel), the ciliary muscles are fully relaxed, the lens returns to its original state, and the focus falls exactly on the retina (very far). When a true myope looks at distant objects, the ciliary muscles relax, and the lens returns to its original state. However, because the axis of true myopia is too long, the focus falls in front of the retina, making it alternately blurry. Near and far objects (which can exercise the ciliary muscles) can treat pseudomyopia, help restore fatigue in hyperopia, but they are not true myopia.
