Why does image clarity decrease in older individuals viewing near objects, even with corrective lenses optimized for distance vision?

💡 Explanation

Decreased image clarity in near vision for older individuals, despite distance correction, occurs because of presbyopia. This is a result of decreased lens elasticity. The ciliary muscles can no longer effectively change the lens curvature for near focus; therefore, accommodation is impaired, rather than pupil constriction or retinal factors being the dominant causes.
