Accommodation to Wavefront Vergence and Chromatic Aberration [PDF]
Optometry and Vision Science, 2011 Purpose. Longitudinal chromatic aberration (LCA) provides a cue to accommodation with small pupils. However, large pupils increase monochromatic aberrations, which may obscure chromatic blur. In this study, we examined the effect of pupil size and LCA on accommodation.

Wavefront Reconstruction of Shack-Hartmann with Under-Sampling of Sub-Apertures
Photonics, 2023 Shack-Hartmann wavefront sensor plays a key role in adaptive optics (AO) systems, which detect the aberrant wavefront by an array of micro-lenslets across the aperture pupil.

Higher-Order Wavefront Aberrations for Populations of Young Emmetropes and Myopes
Journal of Optometry, 2009 Purpose: To test the hypothesis that human eyes have a central tendency to be free of higher-order aberrations by analyzing wavefront aberrations for two young populations of respectively emmetropic and myopic subjects.
