Dear Naveen
 
Myopia:
Myopia is called as shortsightedness.
In this case the person can see a nearby object clearly but cannot see a distant object distinctly.
This is caused when the light rays from a far away object falls at a distance just before the retina.
It can be treated by using concave lenses of suitable power.
It is caused due to excessive curvature of eye lens or elongation of eye ball.
Hypermetropia:
It is called as farsightedness.
In this case the person can see a distant object clearly but cannot see a nearby object distinctly.
This is caused when the light rays from a nearby object falls at a distance behind the retina.
It can be treated by using convex lenses of suitable power.
It is caused when eye ball is too short and when power of lens decreases.
