Horizontal and Vertical Prism Bar Set
The Prism Bar Set provides stepped, clearly marked prism powers in easy-grip bars so you can quickly perform cover-test neutralization, quantify deviations, and assess fusional reserves at distance or near. Available in horizontal (BI/BO) and vertical (BU/BD) configurations, it streamlines pediatric and adult measurements at the chair, slit lamp, or with trial frames.

Vergence Facility Prism 12D/3D – Mounted
The Vergence Facility Prism 12Δ / 3Δ (Mounted) is a two-sided yoked-prism flipper that alternates base-out and base-in demand to train and measure vergence facility efficiently. It provides 12Δ BO (6Δ per eye) on one side and 3Δ BI (1.5Δ per eye) on the other—ideal for timed near drills and recording cycles per minute (CPM) in clinic or supervised home programs.

Yoked Prism 16 Pair
The Yoked Prism – 16 Pair (Flat) set provides sixteen matched prism pairs with the same power and base direction in both eyes, producing a controlled, symmetric field shift without adding fusional demand. Ideal for visual midline shift evaluations, posture/gait and spatial-orientation trials, and vision-therapy progressions, the flat, durable optics make quick chairside swaps and consistent observations easy.
