The hallmark sign of accommodative insufficiency is best described as:

• A. More than 2.00 D below minimum expected amplitude for age
• B. Increased near point of convergence
• C. Normal amplitude
• D. Excess accommodative facility

Answer: (A)

Accommodative insufficiency is defined by a reduced ability to accommodate, especially for near tasks. The key measure is the amplitude of accommodation—the maximum dioptric range the eye can focus from distance to near. When this amplitude is significantly lower than what’s expected for the person’s age (more than about 2 diopters below the minimum expected amplitude for age, per standard norms), that’s the hallmark of the condition. This deficit explains near-vision blur, headaches, and difficulty with reading or close work. In contrast, an increased near point of convergence would point to a convergence problem rather than an accommodative one; normal amplitude doesn’t fit the complaint, and excessive accommodative facility would imply the ability to shift focus very easily, which isn’t characteristic of accommodative insufficiency.
