← Human Body & HealthIf a 55-year-old person is unable to focus on nearby objects, even with maximum effort from their ciliary muscles, which consequence explains this condition of presbyopia?
A)Decreased optic nerve signal transduction
B)Corneal surface irregularity scattering light
C)Lens loses elasticity, reduced accommodation✓
D)Pupillary constriction muscle group weakness
💡 Explanation
Presbyopia arises from the eye's lens losing elasticity with age, impairing its ability to change shape during accommodation; because the ciliary muscles can still contract, but the lens doesn't respond, the near point recedes, therefore blurred vision at close range results, rather than from nerve damage, corneal issues, or pupil constriction failure.
