Relative angle change. Average for all subjects of the mean relative angle change for the different conditions of pupil size and accommodative state for the measured subjects and for the generated virtual subjects. They are compared with the average relative angle change of 20,000 randomly generated PSFs (see text for details). Error bars are ± 1 standard deviation. Asterisk indicates a statistically significant difference with the random case (p < 0.05).
