|Differential diagnosis||Convergence insufficiency.|
AI is generally considered separate from presbyopia, but mechanically both conditions represent a difficulty engaging the near vision system (accommodation) to see near objects clearly. AI is the term used where normal near vision is expected, whereas presbyopia is specifically the loss of accommodation due to age.
