Pathways underlying myopia (nearsightedness) and hyperopia (farsightedness) are different, not opposite, revealed study published in journal PLOS Biology and conducted by Andrei Tkatchenko of Columbia University and colleagues.
Myopia occurs when the eye grows too long, increasing the distance between lens and retina such that the image produced by the lens comes into focus at a point in front of, rather than on, the retina. In hyperopia, the opposite occurs; the eye is too short, and the focal point is behind the retina....
