    Presbyopia is common among people around 40 .As we age ,our eyes will have difficulty in automatically changing focus from seeing at one distance to seeing at another.So if you have to hold your book farther away in order to see clearly , this is an early sign of presbyopia. Although both farsightedness and presbyopia can't see things at close , the reason resulted in them is quite different . Presbyopia is caused by an age-related process while farsightedness is caused by the changing of the eyeball's shape and it is a refractive error of the eye where light from a distant object focuses posterior to the retina. Hope these will not confuse you .
