Question
In recent years, due to long hours of eye use and overexertion, many people have developed myopia. Some suggest that rotating the eyes back and forth can treat myopia. Is this method really effective?
Answer
The rotation of the eyes is mainly controlled by the muscles outside the eye, while the adjustment of vision depends on the ciliary muscles inside the eye. Normally, when we look at distant objects, the ciliary muscles relax completely, and the lens returns to its original state, with the focus precisely on the retina. However, for true myopia sufferers, even if the ciliary muscles relax and the lens returns to its original state, because the axial length is too long, the focus will fall in front of the retina, making distant objects unclear. Rotating the eyes can exercise the ciliary muscles, which has a certain therapeutic effect on pseudo-myopia and also helps to alleviate visual fatigue for hyperopes. However, for true myopia, simply rotating the eyes is not enough to treat it.
