Note on Stereoscopic Acuity and Observation Distance*

Journal of the Optical Society of America, 1958
Stereoscopic thresholds were determined for viewing distances of 0.5 meter and 10 meters in an instrument which essentially eliminates empirical factors to visual depth discrimination. The results with three observers show that there is no change in stereoscopic acuity at these two distances.

Stereoscopic Acuity with Induced Refractive Errors

Optometry and Vision Science, 1983
The relation between refractive error and stereoscopic acuity was investigated by measuring stereoacuity with different combinations of positive and negative spherical lenses over the usual refractive correction. A detailed study was performed on two subjects. In general, there was little change in stereoacuity when the added lenses were of equal power.

Effect of luminance and contrast on stereoscopic acuity

Graefe's Archive for Clinical and Experimental Ophthalmology, 1990
The threshold of binocular depth perception was measured in 11 healthy volunteers. A three-rod arrangement was employed in which both the luminance of the rods and that of the adapting field could be adjusted independently. This allowed fixing the contrast when the effect of luminance was studied or fixing the luminance when the effect of contrast was ...

Cooperative neural processes involved in stereoscopic acuity

Experimental Brain Research, 1979
Results of psychophysical experiments are reported showing that synchrony, appropriate relative placement, and absence of standing disparity are important conditions to be met by members of a target configuration if they are to participate in the cooperative neural processes leading to the best disparity discrimination.
