The main clinical manifestations of myopia include blurred distant vision and clear near-range vision. In the early stage, the distant vision fluctuates and squints when staring at distant objects. In addition to poor distant vision, poor night vision is often associated with higher myopia.
In general, myopic patients may find myopia later because they can get clear vision at a certain point in the near distance without correction.
When you have myopia, you will find that it is impossible for myopia to be 300 degrees, and its degree deepening is a gradual process
