Concept of near sightedness?

It is a very common in now days specially in our elders who old then 40 years they have problem of near or for sightedness, basically near sightedness is a common eye condition where distant objects appear blurry but nearby objects are seen clearly. This occurs when our eye's ball is longer than the normal size of our eye. I don't know probably but i think so that can be a cause of it anyway it is difficult for me.

Concept of far sightedness?

As i said on above that it is really different for me because i am not medical student but from my concept the far sightedness is a common vision condition where nearby objects appear blurry but distant objects are seen clearly. Mostly our olders have face this problem or may be genetic issue can be a cause of this. My mom and father have also that issue they difficulty reading or performing close-up things.

Now an going to invite my friends ; @suboohi, @aaliarubab, @hiralytical for participating in this contest.
