Solution
Concave lens
Explanation:
In short-sightedness (myopia), the eye focuses light rays in front of the retina instead of exactly on it.
A concave lens is used because it diverges (spreads out) the incoming light rays just enough so they can focus perfectly on the retina to form a clear image.
