← Human Body & HealthWhat distinguishes accommodation in a young, healthy eye from an aging eye focusing on a near object?
A)Pupil constriction increases substantially
B)Lens curvature changes are limited✓
C)Vitreous humor refractive index varies
D)Retinal cone cell sensitivity decreases
💡 Explanation
Accommodation declines with age because the lens loses elasticity and the ciliary muscles weaken, thereby limiting the change in lens curvature. Therefore, curvature changes are limited in older eyes, rather than pupil constriction which is mainly light-dependent.
