Designed for use with red/green viewing systems, these high-contrast Black Background Tranaglyph Fusion Cards provide excellent image separation with minimal ghosting. The fixed-demand targets present a range of binocular viewing challenges, progressing from flat fusion activities to more advanced fusion demands.
These cards provide flat fusion activities from approximately 1-3 prism diopters and second- and third-degree fusion demands from approximately 4-28 prism diopters. Base-In (BI) and Base-Out (BO) activities can be performed using the included red/green flipper or by reversing the lens orientation in compatible red/green goggles.
Each set includes five tranaglyph cards and one red/green flipper, making it a convenient addition to professional binocular vision training programs.
