ster·e·o·scop·ic vis·ion

the single perception of a slightly different image from each eye.
Synonym(s): stereopsis

binocular vision

The visual perception of a fused single image from 2 eyes viewing the same object from slightly different vantages. Binocular vision results from the convergence of neural signals from the corresponding points on the 2 retinas on the same binocular cell in the primary visual cortex. If the images received from each eye differ widely in shape, orientation or luminant contrast, the images then rival each other rather than fuse.


Depth perception (three-dimensional vision) provided by fusion of binocular images.
See also: depth perception
Synonym(s): three-dimensional vision.
[stereo- + G. opsis, vision]


The normal ability to perceive objects as being solid. Stereoscopic vision.


The visual perception of depth, or the ability to see three-dimensionally. For this to occur, the person must be binocular.
Mentioned in: Vision Training


Awareness of the relative distances of objects from the observer, by means of binocular vision only and based on retinal disparity. Syn. stereoscopic vision; third-degree fusion. See stereoscopic visual acuity; anaglyph; angle of stereopsis; cortical column; retinal disparity; depth perception; leaf room; stereo-blindness; random-dot stereogram; stereoscopy; Howard-Dolman test; three needle test; two-dimensional test.

The control of the deviation is commonly indirectly deduced during the follow-up from signs like degraded stereopsis, onset of amblyopia, increased deviation, or symptoms like asthenopia, visual discomfort, and diplopia, even if in IXT suppression usually protects from diplopia.
We incorporated a stereopsis measurement system using a phoropter (Topcon VT-10; Topcon Corp., Tokyo, Japan) and two Sony smartphones (Sony Xperia Z5 Premium Dual E6883; resolution, 3840 x 2160; Sony Mobile Communications Inc., Tokyo, Japan) [9].
Many visual changes manifest in AD patients (as already discussed), including alterations in visual acuity, color perception, contrast sensitivity, the visual field, pupillary reflexes, ocular movements, and stereopsis. All can be examined by simple, noninvasive, and easily accessible methods such as adequate ophthalmologic examination, OCT, and electrophysiological examinations.
The visuospatial depth cue of stereopsis was thus not available to the participants in this condition.
Accurate, dense, and robust multiview stereopsis. In IEEE Conference on Computer Vision and Pattern Recognition (CVPR) (Vol.
In order to construct a stereo vision system, two cameras located at two different positions is usually used, which is known as binocular stereopsis based on epipolar constraint.
One limitation of our study is that we did not perform sensory neural tests such as the stereopsis test.
Considering the important effect of various colors of sunglasses on visual performance, this study was aimed to evaluate the effect of different colors of sun glasses on visual acuity, contrast sensitivity, stereopsis and color vision.

The 3-D perception afforded by stereopsis, results from mental summation of the differing views afforded by the two eyes.
These four items were stereopsis (depth perception) testing, light/glare sensitivity testing, fixation/nystagmus testing, and testing phorias beyond cover testing (see Appendix 2, available online only).
