Stereo Fly and Other StereoTests Used in Stereopsis, Strabismus, and Amblyopia Testing

Stereo depth-perception tests, such as the Stereo Fly SO-001, have proven to be an effective and easy-to-use method of screening vision for all ages. They help to identify vision problems and conduct stereopsis, amblyopia, suppression, and strabismus testing, each of which can impede a child's development and performance. Stereopsis tests provide information about depth perception and how the eyes function together as a team.

Stereo Fly SO-001

The Stereo Fly SO-001 is recognized as the standard for stereo depth-perception testing, evaluating both gross stereopsis (2500 to 1200 seconds of arc) and fine depth perception.

The test includes:

• Graded circle test (800 to 40 seconds of arc)
• Animal test for children (400 to 100 seconds of arc)
• One pair of standard 3-D viewers

Stereo Butterfly SO-005

The Stereo Butterfly SO-005 tests and evaluates random dot stereo depth perception for both gross stereopsis (2500 to 1200 seconds of arc) and fine depth perception. The figures present on the test cannot be identified without viewing glasses.
