Description
- The Loose Prism Set (22 pcs) is a calibrated, handheld prism kit for fast, accurate measurement and training of ocular alignment in clinic or vision therapy. Use it to neutralize deviations on cover/alternate-cover tests, quantify horizontal (BI/BO) and vertical (BU/BD) phorias/tropias, and probe fusional reserves; clearly marked base directions and polished optics make readings repeatable at the chair, slit lamp, or with a trial frame.
- What it’s for: Prism neutralization on cover tests, quantifying deviations, checking BO/BI reserves, vertical workups, and VT progress checks
- Kit makeup: 22 calibrated prisms spanning low-to-high powers for fine steps and larger shifts; each with clear base orientation markings
- Clinical speed: Grab-and-go pieces for quick stacking/alternation without changing phoropter settings
- Where it works: Chairside, slit lamp, or in trial frames; equally useful in pediatric and adult exams
- Readability: Etched/printed diopter values and base arrows for confident, repeatable measurements
- VT use: Train convergence/divergence and vertical compensation; document break/recovery and symptom changes
- Good practices: Keep the apex-to-base orientation correct; center over the visual axis; avoid touching optical faces
- Care: Clean with lens-safe solution and a soft cloth; store in the lined case to prevent scratches and keep calibration pristine
