Aging: Presbyopia is the loss of near reading ability due to loss of accommodation of your lens/lens zonules in your eye associated with aging requiring use of reading correction. This starts approximately 40 years old.

Lens gets too stiff: So it can't focus light on the retina as objects get closer.
