From: The time course of the onset and recovery of axial length changes in response to imposed defocus

Group mean VA at each time point during 60 minutes of monocular defocus (Defocus period), and its persistence after 20 minutes of clear vision (Recovery period) during the myopic defocus and control conditions. Error bars represent ± standard error of the mean. Asterisks (*) indicates a significant mean difference from the initial defocused VA (p < 0.05).
