Abstract

We evaluated the visual response to infrared (IR) in humans after dark adaptation. In seven adult participants, visual perception, visual sensitivity, and the visual response to IR after light adaptation were tested. Over the course of dark adaptation, we found visual perception and sensitivity to our experimental IR stimulus increased, while the relative IR intensity necessary for perception decreased. Visual perception of the IR stimulus was abolished during a transient light exposure; however, when turned back off, perception to the IR stimulus returned for all participants. These novel findings may be relevant for both pre-clinical and clinical visual research.
