This test is designed so that it is easy to administer. All items of the Stereo Fly test are manufactured with high quality materials, ensuring sharp long-lasting images.

INSTRUCTIONS for the STEREOTESTS

The Stereo Fly Tests provide an easily administered check of stereoscopic depth perception at any age level. Its purpose is to measure how minutely the two eyes can discern differences in the distances of objects from the observer. Other depth determinants such as size, overlapping, perspective, etc. must be excluded to demonstrate the integrity of the fusion mechanism. Stereo Optical’s Vectogram is an ideal medium for this test. Without introducing instruments or lenses or prisms, the images for the right eye and left eye may be superposed, and stereoscopic disparities introduced in graded steps.

• Evaluate both gross stereopsis (355 to 700 seconds of arc) and fine depth perception
• Graded circle test (800 to 40 seconds of arc)
• Animal test for children (400 to 100 seconds of arc)
• Test includes 1 pair of Standard 3-D Viewers (glasses)
• Answer key provided on back cover
