7-1/2" x 5-1/2" Non-Variable Polarized vectograms ensure testing and training at actuall distances. vectograms stabalize fusion and steropsis, eliminates suppression and develop simulatneous vision. Used in monocular, binocular pursuit and saccadic training, vectograms help correct and prevent anomalies involving projection and hand eye coordination. Ideal for use with Bernell's Dual Polachrome™ Trainer

Aperture Rule™ Set (12 Stereoscope sized cards) These cares are more complex and require more detail demand. They build flexibility, resiliency, attention to detail and reduction of visual fatigue. These cards contain large quantities of details and build large ranges of fusion (leading to high amounts of prism diopters of 'Base Out' and 'Base In' fusion ranges) 12 Cards
