The Lang-Stereotest® II is used to test binocular spatial vision (stereopsis) in infants, children and adults. -
The Lang-Stereotest® I-R is an easy-to-use screening-test designed for early detection of problems with stereoscopic vision of children. In contrast to most stereo tests it does not require glasses, due to the combination of random dots and a lenticular screen. -
The Lang-Stereopad® is a new device for testing global near stereopsis. It is suitable for all age groups, including preverbal children (less than 1 year). This stereo test does not require the use of special glasses because of the combination of random dots with a lenticular screen, similarly to the the Lang-Stereotests® I-R and II. -
The Lang Fixation Stick has been designed by J. Lang for the assessment of eye fixation, motility, accommodation, convergence, for cover test, and to prepare the patient for testing with the Lang-Stereotest® or the Lang-Stereopad®. -
The Lang Fixation Cubes have been designed by J. Lang for the assessment of eye fixation, motility, accommodation, convergence, for cover test, and to prepare the child for testing with the Lang-Stereotest® or the Lang-Stereopad®.
5 child-friendly objects are presented on the side and the top of the cube. Some of them are also included in the two versions of the Lang-Stereotest® and of the Lang-Stereopad®, and on the Lang Fixation stick.
The Cube has a white handle.
Each turn of the cube shows a new object. The star on the top side and the other objects can also be used for the test of convergence.

All Frisby Stereo Test Present "real depth" objects viewed with natural vision: no testing glasses are required. Each plate has four random-pattern squares with a circle of pattern elements lying in depth relative to its surround. The depth effect is due to the circle and its surround being printed on opposite sides of the plate. The Frisby Stereo Test has 3 plates allowing for testing stereo acuity disparity as fine as 15 seconds of arc. -

Each plate has four random-patten squares, with a circle of pattern elements, lying in depth relative to its surround. The depth effect is due to the circle and its surround being printed on opposite sides of the plate. The purpose of the Frisby Screening Stereo Test - Single Plate, is to demonstrate the presence of stereopsis. -
