Answer 2

Presbyopia and Hypermetropia both are the eye defects associated with the vision for the close objects.

(I). It is a vision condition in which the crystalline lens of eye loses its flexibility,which makes it difficult for you to focus on close objects, Whereas in Hypermetropia,It is the commonly known as Farsightedness can be secondary to an abnormality of the lens or cornea.

(II).Presbyopia occurs because , over time, the lens of the eye can become inflexible and more rigid, whereas Hypermetropia occurs when your eyes keep light from properly lining up with the retina.

(III)Presbyopia occurs as a result of changes in the natural lens inside the eye, whereas Presbyopia occurs as a result of a misshappen of cornea.

(IV)In Presbyopia,It is cause is hardening of lens and weakening of ciliary muscles over time,whereas, In Hypermetropia,Is is not caused by hardening of lens and weakening of ciliary muscles over time.

(V)Presbyopia can occur from childhood or birth,whereas,Hypermetropia does not occur from childhood.
