This Non-Illuminated Double Slide Holder greatly simplifies vision therapy by holding slides at the proper angle. The slides can be slid to the 'breaking point' and back to the 'recovery point'. The viewer supports the full extension of the panels to their maximum base-in and base-out capabilities. The white background supports base-out vergence work (convergence) and can be removed to reveal a clear background. This permits the use of the slides for fusional divergence work which requires that the patient view beyond the plane of the target.
This unit is designed to hold to provide a universal fit to include tranaglyphs, Stereo Optical Vectograms, and VAC Vectographs.
Note: Vectographs pictured are not included with the viewer.
