← Human Body & HealthWhy does an aging eye lose near focus accommodation, impacting lens curvature?
A)Pupil dilation decreases light intake
B)Lens elasticity decreases altering curvature✓
C)Retinal sensitivity diminishes with age
D)Corneal refraction increases with dehydration
💡 Explanation
Presbyopia occurs because the lens gradually loses elasticity, impairing its ability to change shape; therefore, the curvature can no longer adjust for near vision. The ciliary muscles can still contract, rather than loss of muscle function being the primary issue.
