Short sightedness is actually called myopia .In this defect, a person is not able to see the far away objects clearly .It is because the image is not formed on the retina properly.This is caused due to weakening of ciliary muscles or due to variation in size of eye ball . This defect is cured by using concave lens of suitable focal length.
Ray diagram is well shown on textbook
