Stereo Acuity Test (Butterfly)

This Stereo Test is used as a standard in stereo vision testing. It is useful in rapidly evaluating gross and fine stereopsis, including amblyopia and strabismus testing. It is an easy-to-administer, rapid, and effective test for all ages, particularly well suited for children. The test helps identify stereopsis vision problems such as amblyopia and strabismus, which, in children, can impede development and performance. The test presents a large image of a fly, especially useful for testing children who typically respond to large objects and images. The test is a high quality stereopsis and depth-perception test manufactured with high quality, long lasting images.
