Titmus Stereo Fly Test Classic Manual Analog

The Titmus Stereo Fly Test Classic Manual Analog is a non-electronic vision screening tool used to assess stereoscopic depth perception and binocular vision. The test combines a large fly image for gross stereopsis assessment, graded circle targets for fine depth perception, and animal targets designed for younger patients. The patient views the test through polarized 3-D glasses at a standardized near distance. It is suitable for ophthalmology clinics, optometry practices, paediatric eye care, school vision screening and other settings where stereopsis, amblyopia, suppression or strabismus assessment is required.
