Product description
- The Stereo Fly Test – Standard is a near-vision booklet used with polarized glasses to check whether both eyes work together to see true 3D (depth). Patients first view a large fly whose wings should appear to “lift” off the page if basic (gross) stereopsis is present; then they move to animal pictures and graded circles that measure finer levels of depth perception. It’s quick (a few minutes), intuitive even for non-readers (just point to what looks raised), and useful for spotting potential eye-teaming problems such as amblyopia (lazy eye) or strabismus that may warrant a full exam.
- Includes: Booklet + polarized glasses
- Use distance: About 40 cm (16 in) in normal room light
- What it measures: Gross stereopsis (fly) and fine stereo (animals & graded circles, typically down to ~40 arcsec)
- Who it suits: Children and adults; great for clinics, screenings, and quick checks
- Why it’s effective: Highly engaging “pop-out” images make cooperation easy, especially for young children
- Note: This is a contour stereotest (not random-dot), so minor one-eye clues can exist; many clinics pair it with a random-dot test for confirmation
