Solution 1

Presbyopia is an age-old eye defect. In this condition, the lens loses flexibility resulting in far-sightedness.

Cataract is also very common in old people, the cornea becomes opaque and the vision is cut down even to blindness.

Hypermetropia. It is caused due to flattening of the eye lens (Also presbyopia in which lens looses flexibility).
