Previous studies have suggested that targets illuminated by monochromatic (narrow-band) light are less effective in stimulating the eye to change its focus than are black-white (broadband) targets. The present study investigates the influence of target spectral bandwidth on the dynamic accommodation response in eight subjects. The fixation target was a 3.5-cycle/deg square-wave grating illuminated by midspectral light of various bandwidths [10, 40, and 80 nm and white (CIE Illuminant B)]. The…

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.

Cone contributions to signals for accommodation and the relationship to refractive error

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.

Dynamic Accommodation Responses to Stationary Colored Targets

Viewing multichromatic targets does not increase significantly the variation in accommodative response as compared with broadband black-and-white targets, and responses to near-isoluminant targets were not more variable than to the standard target.

The effect of ocular aberrations on steady-state errors of accommodative response.

It is concluded that the one-to-one stimulus/response slope in accommodation function should not always be considered as ideal, because higher order aberrations, especially changes of spherical aberration, may influence the actual accommodative demand.



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.
