Myopia (nearsightedness) and hyperopia (farsightedness). A Myopia (nearsightedness) and hyperopia (farsightedness). A. The normal eye focuses light from a distant point on the retina with the ciliary muscles relaxed. B. Myopia results when the eyeballs are longer than normal, causing light to be focused on a point in front of the retina. Myopia can be corrected using eyeglasses with a concave lens. C. Hyperopia results when the eyeballs are shorter than normal, causing light to be focused behind the retina. Hyperopia can be corrected using eyeglasses with a convex lens.
