Question

what are the basic reason for hypermetrophia? how they can be treated

Answer 1

Hypermetropia is a defect of vision in which a person can see distant objects clearly and distinctively, but is not able to see nearby objects comfortably and clearly. 



Hypermetropia is caused due to

reduction in the curvature of the lens

decrease in the size of the eyeball

Since a convex lens has the ability to converge incoming rays, it can be used to correct this defect of vision.
