The screening cards "Visopter" test the most important aspects of binocular vision in short.

With these cards you can test possible phorias or disorders in the binocular vision, as well as the fusion at far and near. Each card is named with the test method and the setting for the Visopter (or any other Brewster stereoscope). This lowers the risk of an error. The cards are DIN long and will fit perfectly into the Visopter, but can also be placed on a Bernell-O-Scope or Bioptor.
