Myopia (Short Sightedness)

Myopia (Short Sightedness) Myopia results if the lens curvature is too great or the entire eyeball becomes elongated. Light rays entering the eye are refracted more than is necessary. Consequently light is focused in front of the retina. The image perceived is thus blurred. The condition is called short-sightedness as objects near the eye are clearer than those further away. Myopia can be corrected by placing a concave lens in front of the eye. The surface of the concave lens refracts light rays in such a way that the rays diverge slightly from their original path. The lens of the myopic eye now refracts the diverged light rays in to focus on the retina. www.edufine.net
