For near vision, this instrument can be used either with a single line of letters in the card holder and the septum removed or using a stereoscope card with separate right and left eye pictures and with the septum in place. This may support the clinical observation that when exercises are carried out under more natural free-space conditions, improvements in visual function are more likely to translate into everyday life.

One viewpoint, typified by Vaegan (1979) , is that the details of the exercises are relatively unimportant, and the key feature is to maintain an overconverged posture for as long as possible.

Brain. 10.3 also shows that if the card distance is increased without changing the separation of the pictures, i.e., the card holder is drawn away from the patients eyes, the picture separation will now be narrow for the new card distance and therefore convergence will be required to maintain fusion.

Prescribing based on the vertical associated phoria is generally accepted as the best way to determine the proper amount of prism to treat symptomatic vertical heterophoria.
