Chromatic stimulus for accommodation to stationary and moving targets
TLDR
Most subjects accommodated accurately in the normal condition at all three stimulus distances, a few subjects had difficulty maintaining focus in monochromatic light at the near (5 D) or far (0) stimulus distance, and most subjects could not maintain focus at both the near and far distances with LCA reversed.
Control of accommodation by longitudinal chromatic aberration and blue cones.
TLDR
OAB appears to be controlled more by the parafovea than by the fovea, which is in line with the assumption that OAB is mediated by the short-wavelength-sensitive cones that are absent from the centralfovea in most subjects.
Adaptation to the eye's chromatic aberration measured with an adaptive optics visual simulator.
TLDR
The results suggest that some LCA neural adaptation may exist, particularly for low contrast VA, which impacts the performance of vision under corrected LCA, and possibly prevents measurement for immediate visual benefit.
Impact of longitudinal chromatic aberration on through-focus visual acuity.
TLDR
Low capability of the model to predict VA in modified LCA conditions suggests that neural adaptation may play a role in how LCA manipulation affects the depth of focus.
Accommodation to static chromatic simulations of blurred retinal images
TLDR
Subjects’ accommodation responses were consistent with the hypothesis that LCA provides a stimulus to accommodation, and thus is an important stimulus for accommodation in everyday situations.
Potential signal to accommodation from the Stiles–Crawford effect and ocular monochromatic aberrations
TLDR
If cues within the blurred retinal image due to the Stiles–Crawford effect and the eye's monochromatic aberrations can drive accommodation with a small pupil that is typical of bright photopic conditions is investigated.
Does display phosphor bandwidth affect the ability of the eye to focus?
The focusing response of the eye (accommodation) is degraded in monochromatic light for many subjects. To find out whether this degradation also occurs in narrowband polychromatic light, we measured

Results support the view that the system monitors focus by comparing contrast in red‐green and perhaps blue‐yellow colour‐opponent mechanisms, but is most prominent between 3 and 5 c/deg.

TLDR
The results are consistent with previous reports of a sizable region of reasonably good optical quality extending into the retinal midperiphery, and lateral chromatic aberration approximates the average spacing between adjacent retinal cones, indicating that it does not substantially limit peripheral color vision.

TLDR
The results indicate that lateral chromatic aberration is a major factor affecting image quality for obliquely incident rays of polychromatic light, and probably has negligible effect on peripheral acuity but may act to limit aliasing of peripheral patterns.
Accommodation and color.
TLDR
The monocular, steady-state response to targets under various colors of illumination is investigated and it is shown that the ocular longitudinal chromatic aberration increases slightly with accommodation.
