Description
The Stereo Optical S0005 Butterfly Stereotest is designed to assess stereoscopic depth perception and binocular vision through random-dot testing. Its targets cannot be recognized without polarized viewing glasses, helping reduce monocular clues during the examination.
The butterfly target evaluates gross stereopsis from 2,500 to 1,200 seconds of arc. The test also includes graded circles for measuring finer stereoacuity from 800 to 40 seconds of arc and child-friendly animal targets ranging from 400 to 100 seconds of arc.
Its portable booklet format makes it suitable for optometry, ophthalmology, pediatric evaluations, school screenings, and other clinical vision-testing applications. One pair of Standard 3-D Viewers and an answer key printed on the back cover are included.
