Explanation:
Shortsightedness is corrected using a concave (curved inwards) lens which is placed in front of a myopic eye, moving the image back to the retina and making it clearer. Longsightedness is corrected using a convex (outward facing) lens.

Answer:
In a myopic eye, the image of a distant object is formed in front of the retina and not at the retina itself. A concave lens causes light rays to diverge before they strike the lens of the eye so that the image is formed on the retina. Hence, a concave lens is used to correct myopia.
