What age-related refractive condition involves gradual progressive loss of crystalline lens elasticity and near accommodation?
Answer and explanation
Correct answer: D. Presbyopia
- Step 1: With advancing age (typically after 40-45 years), lens fibers lose elasticity and ciliary muscle tone decreases. Step 2. The near point recedes beyond normal reading distance due to failed near accommodation, defining presbyopia. Answer: Presbyopia. Why not the others: Myopia is axial elongation; Strabismus is ocular misalignment (squint); Amblyopia is lazy eye development.
