Short-sightedness. Illustration of a cross section of an eye with short-sightedness. In short-sightedness, or myopia, the eyeball is longer than it should be, or the lens is the wrong shape, and light is focussed in front of the retina. This causes difficulty focussing on distant objects, which appear blurred. It can be corrected by placing a concave lens in front of the eye. | |
