(1) Numbers: a total of 400 participants were gathered through an interview in our study aged between 45 and 70 years. Besides this, 240 subjects were enrolled in experiment 2 and 160 participants were separated for experiment 3 for persons with a mean age of 50 years. (2) At first, we gained the AA from subjects with different ages using the subjective push-up method. Subsequently, AA may be converted to the additional diopters of presbyopic reading glasses. (3) Near vision: test at 40 cm in front of the volunteers’ eyes. (4) Age (mean age) in years. (5) AA: amplitude of accommodation. (6) D: Diopter.
