Explanation

Short-sightedness (myopia) occurs when the eye focuses images in front of the retina instead of on it. A concave lens diverges light rays before they enter the eye, pushing the focal point back onto the retina and correcting the vision. Convex lenses are used for farsightedness (hyperopia).
