Adaptation of humans to colored split-field glasses

Abstract“Split-field” glasses, consisting of a red filter before the left half-field of each eye and a green filter before the right half-field, were worn by three observers. The colors in the glasses did not seem to diminish in saturation as Kohler (1951) has reported, even after as long as 146 days. A very small change in perceived color could be noticed as the gaze was moved back and forth from right to left without the glasses on, but this may have an explanation at the ocular level.
