  3. The difference between myopia and hypermetropia is that a myopic person is only able to see the near or short distance objects clearly. In contrast, a hypermetropic person is only able to see the far or distant objects clearly. Both myopia and hypermetropia are the type of eye diseases that are based on the distance to see the object
