Question

why cant old people see near or distant objects clearly?

Answer 1

With age the coordination of brain with other parys of body decrease due to which the vision of old people is weak

Answer 2

old people cant see near or distant objects clearly as they suffer from presbyopia, a combination of myopia and hypermetropia.
this happens as the cilliary muscles in the eyes get weak with age and therefore are unable to adjust the focal length of the crystalline lens of the eye
