<title>Assessment of ocular stereovision prevalence and eye dominance stability</title>

subject

description

The paper reports on the development of the equipment for studies of the eye dominance and ocular stereoprevalence by using black-and-white and color stereostimuli. The stereostimuli are separated either by color-filter goggles or phase separating liquid-crystal-shutter goggles. The stability of the stereoprevalence is studied by artificial step-by-step deterioration of the retinal image quality, particularly in the dominant eye. The stimuli are blurred using spatial Gaussian filtering. The polymer-dispersed-liquid-crystal cell placed in front of the dominant eye induces a controllable light scattering. The stimuli-blurring and light-scattering methods exhibit different influence on the eye ocular prevalence. Blurring causes a smooth change of the prevalence towards the nonblurred stimuli eye. The influence of moderate scattering depends heavily on stimuli color. At a sufficiently high scattering level the instable switching from the prevalence of one eye to the prevalence of the other occurs.
