The visual system appears to have the ability to analyze polychromatic blur to determine the state of focus of the eye for the purpose of guiding the accommodation response, and the eye focuses more accurately on targets of wider spectral bandwidth.

Ocular accommodation and wavelength: The effect of longitudinal chromatic aberration on the stimulus–response curve

Pupils and accommodative responses as well as visual acuity under narrowband light-emitting diode (LED) illuminants of different peak wavelengths and within the accommodative range of observers, accommodative errors were small and visual acuity normal and when accommodation was accurate, visual acuity was worst for blue narrowband light.

Accommodation and wavelength: the effect of longitudinal chromatic aberration on the stimulus-response curve

Observers were able to accommodate under narrowband light and compensate for the LCA of the eye, with no difference in the variability of the steady-state accommodation response between narrowband and broadband illuminants, and intriguingly, subjects compensated more fully for LCA at nearer distances.

Accommodation without feedback suggests directional signals specify ocular focus

Accommodation to monochromatic and white-light targets.

Accommodation to monochromatic targets is not as accurate as accommodation to a white-light target, and this effect is related to the presence of ocular longitudinal chromatic aberration for the white- light target.

Accommodation to Wavefront Vergence and Chromatic Aberration

Large individual differences in accommodation to wavefront vergence and to LCA are a hallmark of accommodation, and LCA continues to provide a signal at large pupil sizes despite higher levels of monochromatic aberrations.

The role of short-wavelength sensitive cones and chromatic aberration in the response to stationary and step accommodation stimuli

Accommodation to static chromatic simulations of blurred retinal images

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.

The State of Accomodation during the Measurement of Axial Chromatic Aberration of the Eye*

The conclusion is made that the accommodative state does not in this case respond automatically to changes in the vergence of light falling in the retinal plane, and it is suggested that some other stimulus, perhaps perceived distance, predominates.

Accommodation and color.

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.

A neural and computational model for the chromatic control of accommodation

A computational model for how the visual system uses the extra information in polychromatic stimuli to increase the accuracy of accommodation responses is developed and it is found that chromatic cues to accommodation are extracted most effectively by neurons responding to spatial frequencies of between 2 and 8 cycles/deg.

Spatiotemporal chromaticity discrimination.

The experiments indicate that no resonance phenomena occur in the spatiotemporal color-discrimination system of the eye, and show that the threshold chromatic contrast is proportional to the square root of the illuminance.

Failures of isoluminance caused by ocular chromatic aberrations.

The authors' calculations show that all three chromatic aberrations can introduce luminance modulations in the retinal images of isoluminant gratings and can be more detectable than the original color contrasts at spatial frequencies above 3 cycles/deg.

Red‐green opponent channel mediation of control of human ocular accommodation.

To find out whether the red‐green channel by itself could influence the accommodative response, it was isolated through chromatic bandpass filtering and measured accommodation under dynamic and static conditions.

Sensitivity to spatiotemporal combined luminance and chromaticity contrast.

Contrast-detection thresholds for various combinations of chromaticity and luminance differences were obtained for spatiotemporal square-wave modulation of a yellow field and it seems that a simple threshold function appears to be sufficient to describe the experimental data.
