← Human Body & HealthWhy does the lens curvature change dynamically during accommodation in the eye?
A)Maintains constant refractive index
B)Optimizes focal distance on retina✓
C)Controls vitreous humor pressure
D)Regulates choroidal blood flow
💡 Explanation
The lens curvature changes because ciliary muscle contraction alters tension on zonular fibers, thereby changing lens shape. This dynamic adjustment optimizes focal distance, focusing images on the retina for clear vision, therefore acuity is maximized rather than other functions related to pressure or blood flow.
