Summary[edit]

Description
English: Duane's classical curve (1922, Fig. 4) showing the amplitude or width of accommodation as changing with age. Mean (B) and approximate upper (A) and lower (C) standard deviation are shown. The legend in the original paper claims A and C were extreme values but from Fig. 3 in the same paper it is apparent that this is not the case.
