Stereopsis without correspondence
Philosophical Transactions of the Royal Society B: Biological Sciences, 2022 Stereopsis has traditionally been considered a complex visual ability, restricted to large-brained animals. The discovery in the 1980s that insects, too, have stereopsis, therefore, challenged theories of stereopsis. How can such simple brains see in three dimensions?

Clinical evaluation of stereopsis
Vision Research, 2013 Principles of the design and administration of clinical stereopsis tests are outlined. Once the presence of the distinct sense of the third dimension by binocular vision alone and without help from monocular cues has been established in a patient, the examination can proceed to the measurement of stereoscopic acuity. Best results are obtained with high-

The Functional Significance of Stereopsis
Investigative Opthalmology & Visual Science, 2010 Purpose. Development or restoration of binocular vision is one of the key goals of strabismus management; however, the functional impact of stereoacuity has largely been neglected. Methods. Subjects aged 10 to 30 years with normal, reduced, or nil stereoacuity performed three tasks: Purdue pegboard (measured how many pegs placed in 30 seconds), bead ...

Induction of Monocular Stereopsis by Altering Focus Distance: A Test of Ames’s Hypothesis
i-Perception, 2016 Viewing a real three-dimensional scene or a stereoscopic image with both eyes generates a vivid phenomenal impression of depth known as stereopsis. Numerous reports have highlighted the fact that an impression of stereopsis can be induced in the absence ...

Progressive changes in binocular perception from stereopsis to rivalry
Frontiers in PsychologyIntroductionThe binocular system provides a stereoscopic view from slightly different retinal images and produces perceptual alternations, namely, binocular rivalry, from significantly different retinal images.

Stereopsis and Depth Perception
, 2019 Humans and some animals can use their two eyes in cooperation to detect and discriminate parts of the visual scene based on depth. Owing to the horizontal separation of the eyes, each eye obtains a slightly different view of the scene in front of the head.
