← Human Body & HealthWhy does progressive presbyopia usually develop when individuals maintain prolonged near focus on digital screens, despite using corrective lenses?
A)Lens proteins become more opaque
B)Retinal fatigue reduces image clarity
C)Ciliary muscle loses elasticity over time✓
D)Intraocular pressure consistently decreases
💡 Explanation
Presbyopia progression occurs because the ciliary muscle, responsible for lens accommodation, loses elasticity with age and sustained contraction during near-focus activities. Therefore, the lens can't adequately adjust for near vision, rather than lens protein opacity or pressure changes.
