Answer 1

Answer:

Presbyopia. This defect of vision usually happens in old age when ciliary muscles become weak and can no longer adjust the eye-lens. The muscles become inflexible in this condition and cannot see nearby objects clearly. The near-point of an old person having presbyopia is much more than 25 cm.
