A custom-developed polychromatic AO system at the Visual Optics and Biophotonics Lab (Institute of Optics, Spanish National Research Council, IO-CSIC, Madrid, Spain) was used in this study to correct the subject's aberrations and to induce aberrations in on-bench control experiments. The system and all its channels have been described in detail in previous publications (
Vinas et al., 2015;
Marcos et al., 2017;
Vinas, Aissati, et al., 2019;

All optoelectronic elements of the system (SCLS main source, AOTF, Badal system, pupil cameras, HS wavefront sensor, deformable mirror, and DMD) were automatically controlled and synchronized using ready-made or custom-built software programmed in Visual C++ and C# (Microsoft, Redmond, WA, USA) and MATLAB (MathWorks, Natick, MA, USA).
