If a 55-year-old person struggles to read fine print despite corrective lenses for distance, which process explains why the ciliary muscle's behavior leads to this specific vision change?

A)Reduced aqueous humor production increases pressure
B)Decreased corneal elasticity distorts incoming light
C)Lens stiffening reduces accommodation amplitude
D)Vitreous humor clouding scatters incoming light

💡 Explanation

Presbyopia develops because the lens loses elasticity, decreasing its ability to change shape when the ciliary muscle contracts. Therefore, the lens stiffening reduces accommodation, rather than other age-related changes like humor alterations causing the near-vision issue.
