In a recent study performed at the laboratory of the University of Valencia we have investigated the potential effect that odd and even-order monochromatic aberrations may have on the accommodation response of the human eye. Eight healthy subjects participated in the study and using an adaptive optics system we measured the accommodation response of the subjects under different conditions: with the natural aberrations being present, and with the odd and even-order aberrations being corrected. Three measurements of accommodation response were monocularly acquired at accommodation demands ranging from 0 to 4 D (0.5 D step). Our results revealed that no statistically significant differences were found between the accommodation responses under the three conditions. Then, the odd and even-order aberrations were not helping the visual system to accommodate, because their partial correction did not affect the accommodation performance.
