Shortsightedness cannot be corrected by the use of convex lens ,why?​

In this case ,the parallel Ray's coming from distant objects are focused in front of the retina. Then again if we use convex lens , it converger more . As a result , person can't see. Due to this reason , short sightedness can't be corrected by use of a convex lens
