← Human Body & HealthIf a 60-year-old individual with developing presbyopia views objects at varying distances, why do near objects appear blurry compared to distant objects?
A)Decreased retinal pigment regeneration occurs
B)The vitreous humor becomes increasingly opaque
C)Pupillary constriction impairs light refraction
D)Ciliary muscle contraction weakens over time✓
💡 Explanation
Presbyopia results from age-related decline in the ciliary muscle's ability to contract and change lens shape, because this reduces the lens's ability to accommodate for near vision. Therefore, near objects appear blurry, rather than far objects, because focusing on them requires greater accommodation.
