What is Binocular Visual Dysfunction (BVD)? The first step with any of these exercises is to demonstrate physiological diplopia and the easiest method is to use two fairly large and obvious objects as targets, for example, two pencils. The restricted field, stimulation of proximal convergence and other disadvantages of this type of instrument do not seem to affect its use for training fusional reserves. If a variable prism stereoscope is used for distance vision, the card holder is removed, and the patient looks across the room. Procedure, Recovery, Cost.
