Stereopsis

  • 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 red 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.

  • The magnetic monopod support has been designed specially to be used with the Lang-Stereopad®. The test plate can be easily placed in reading position on a table, both in portrait and landscape position. The magnetic monopod serves also as a handle on the back side of the test plate when the test needs to be shown in frontal position.
  • 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-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.
  • Frisby Stereo Test - 3 Plates
    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.
  • Frisby Stereo Test
    All Frisby Stereo Test Present "real depth" objects viewed with natural vision: not testing glasses are required. 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.
  • TNO Test for Steroscopic Vision
    Suitable for testing very small children (2 1/2 to 5) as well as adults. Three plates for screening, 3 for diagnostic. Kit includes seven plates and red/green glasses.
  • Stereo Vision Chart Series
    Upgrade your vision therapy to a whole new level with the Stereo Vision Chart Series. Patients love stereo targets, but often we cannot send them home...until now! With the Stereo Vision Chart Series, you have access to economical and efficient training tools to integrate binocular vision training while training other visual skills simultaneously. The Stereo Vision Charts provide an excellent fusion lock and a wonderful depth of field. The depth is subtle and great for working with just noticeable differences (JNDs). They are great for working with pilots, athletes and others who want to refine their depth perception awareness.
