Not exactly, actually, when the eye's optical power and length do not match perfectly, vision will not be in focus. If your distance vision is blurry, but close-up objects are clear, you are myopic. If you are hyperopic, you can see clearly in the distance but only by expending more focusing effort than normal, and even more effort for up close. Myopic and hyperopic are different and it was found that almost all hyperopic and emmetropic eyes showed an age-related gyperopic shift, but only a small proportion of myopic eyes shifted toward hyperopia, with others remaining relatively stable and still others increasing in myopia.
