Myopia, or nearsightedness, is a refractive error where light is focused in front of the retina instead of directly on it, causing distant objects to appear blurred. To correct myopia, a diverging lens is needed to spread out the light rays before they enter the eye so that they focus correctly on the retina. A concave lens is a diverging lens.
Myopia is corrected by using
