Model for color vision and light adaptation.

A multizone color model is described. It has nonlinear receptor gain control, two postreceptor opponent-colors processing stages, and neural compression late in the visual pathway. It is assumed that gain control can be activated by receptor responses from a test light itself (self-adaptation) and (or) by receptor responses from other adapting fields. Apparent brightnesses and visual discriminations are mediated by the first processing stage, and apparent hues and saturations are mediated by the second stage. The model accounts for a wide range of data, including nonlinear hue shifts in the color solid, various apparent brightness effects, visual discriminations for achromatic and chromatic lights under various adaptation conditions, and effects of chromatic adaptation on color appearances.

[Color vision disturbance in laser operators and patients: comparison of argon and dye lasers].

Color contrast sensitivity was measured in laser operators before and after laser sessions. The tritan threshold was elevated after the sessions in all laser operators who had used argon (blue-green) lasers. No change was observed when lasers with longer wave-lengths were used. Elevation of the tritan threshold to above-normal levels was observed even before laser sessions. The thresholds remained increased even when the laser operator did not use a laser for 3 weeks. Thus, it appears that the damage caused by the argon blue-green laser is cumulative. Elevated tritan thresholds were also observed in patients with peripheral retinal breaks who were treated with an argon (blue-green) laser.
