← Human Body & HealthWhy does accommodation lag during rapid shifts from far to near objects in individuals with presbyopia?
A)Increased vitreous humor viscosity impedes refraction
B)Pupil constriction reflexes diminish light adaptation
C)Retinal cones exhibit reduced photosensitivity levels
D)Ciliary muscle elasticity declines, slowing lens change✓
💡 Explanation
Presbyopia is age-related, reducing near vision because the ciliary muscle's ability to change the lens shape decreases due to loss of elasticity. Therefore, the accommodation response slows down considerably, rather than issues involving retinal adaptation or vitreous changes.
