Binocular Rivalry

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Why do people have two forward-facing eyes? By presenting the brain with two ever so slightly different images it becomes possible to comprehend visual problems that are far more difficult to process through a single eye. Chief among these is the problem of 3-D perception, seeing the world in three dimensions, despite retinal inputs in only two dimensions. What happens if each eye receives two completely different images? That...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Attention refers to the limited human ability to select some information for processing at the expense of other stimuli in the environment. Attention operates in all sensory modalities: vision, hearing, touch, even taste and smell. It is most often studied in the visual domain though. A common way to study visual attention is with a spatial cueing paradigm. This paradigm allows researchers to measure the consequences of focusing...

Binocular rivalry occurs when the eyes are presented with different images at the same location: one image dominates while the other is suppressed, and dominance alternates periodically. Rivalry is useful for investigating perceptual selection and visual awareness. Here we describe several easy methods for creating and using binocular rivalry stimuli.

We discuss a novel method forviewpoint-rotation of visual stimuli, and demonstrate using a mirror stereoscopethe three-dimensional percept of rotation-in-depth. The technique can be used to investigate the role of stereoscopic cues in encoding viewpoint-rotated figures.

Comparison of Agreement and Accuracy using Binocular Wavefront Optometer with Autorefractor and Phoropter

The binocular wavefront optometer agrees well with traditional refraction techniques in both objective and subjective refraction measurements, offering superior accuracy and clinical utility. Its standardized protocol reduces optometrist workload and provides a more accurate refractive assessment for post-refractive surgery individuals.
FAQs
Binocular disparity gives the brain two slightly different retinal views of the same scene. Comparing these views reveals differences associated with an object’s position relative to other parts of the scene. This comparison supports judgments of distance and three-dimensional structure, making disparity central to stereoscopic vision and spatial awareness.
Eye convergence supplies information through the changing alignment of the eyes as they view objects at different distances. Differences in convergence help the brain interpret whether an object is relatively near or far. This signal complements retinal-image comparison, allowing depth perception to draw on more than one aspect of coordinated binocular viewing.
These cues provide related but distinct information about spatial layout. Binocular disparity comes from comparing the two retinal images, whereas convergence reflects how the eyes are positioned while viewing an object. Using both signals helps the visual system form a more informative representation of depth, distance, and three-dimensional structure.
Binocular cues offer a way to examine how the visual system transforms information from coordinated eye function into perceptual experience. Research can use them to investigate stereoscopic vision, depth perception, and spatial awareness. They are also relevant to perceptual development, because changes in binocular processing can affect how three-dimensional scenes are understood.
When the eyes do not function in a coordinated way, the information needed for binocular processing may be disrupted. Studying binocular cues in this context can help researchers connect eye coordination with depth perception and spatial awareness. This provides psychological insight into how altered visual input influences the experience of three-dimensional structure.
Three-dimensional displays and virtual reality systems can use binocular principles by presenting visual information that supports separate views for the two eyes. The resulting image differences can engage binocular disparity, while the viewing arrangement can relate to convergence. These applications use mechanisms of stereoscopic vision to create an experience of depth and spatial structure.
