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

Abstract: 1. It has been hypothesized, but not verified empirically, that the control of human ocular accommodation is mediated by either the red‐green or yellow‐blue colour channels. Our goal was to determine experimentally whether the red‐green channel by itself could influence the accommodative response. 2. To find out, we isolated the red‐green channel through chromatic bandpass filtering and measured accommodation under dynamic and static conditions. The effect of this filtering was to modulate the red‐green channe… Show more

“…A highly accurate and stable response would be expected with this target because of its wide spectral bandwidth 18,22 and high luminance contrast. 1 The black-on-blue and black-on-red targets provided high luminance contrast but had reduced spectral bandwidth.…”

“…12,18,19,22 For steady targets, the accommodation response becomes less stable, showing low frequency drifts and increased fluctuations that suggest subjective difficulty. 20 The amplitude of accommodation may also fatigue slightly during work performed under monochromatic illumination.…”

“…Probably not. It turns out that humans use chromatic aberration as an important clue to drive accommodation (Fincham, 1951;Flitcroft, 1990;Kruger & Pola, 1986;Kruger et al, 1993;Kotulak et al, 1995), so eliminating chromatic aberration would be detrimental to perception of dynamic natural images.…”
