title: [Dynamic stereovisometry].
abstract: An original method of dynamic stereovisometry and a device for its realization Stereovisotest have been developed for examining the stereoscopic vision. Dynamic stereovisometry permitted the detection of positive and negative thresholds of stereoperception starting from the age of 4 years with an accuracy of 1 second of arc. The mean age-specific thresholds of stereoscopic vision were determined for a random sample of 1810 subjects aged 4 to 60 with binocular vision. For children aged 4 to 6 the mean threshold is 80 seconds of arc, in schoolchildren and adolescents it gradually reduces to 55 seconds of arc by the age of 16-20, from 21 to 40 the threshold remains at the level of 45 seconds of arc, after which it starts to increase and reaches 60 seconds of arc by 60. Stereoscopic vision of subjects whose profession requires precise vision was examined and criteria for vision assessment offered. Training of stereoscopic vision using the Stereovisotest device were carried out. The possibility of raising the thresholds of stereoscopic perception to physiological ones has been demonstrated.
