CVS is a sophisticated yet easy-to-use vergence exercise computer application that your patients can run on nearly any PC. The program is portable and runs trouble free on most desktop computers commonly found in patients’ homes, schools and libraries. CVS encourages and motivates your patient by continuously evaluating their progress and making the exercises more challenging whenever the goals are achieved.

To assure compliance CVS uses Random-Dot Stereograms. Each exercise requires bifovial fixation for correct responses. The responses required are a simple choice of four arrows keys; up, down, left or right. The results of each exercise session are documented as the program notes the date, duration and results of each exercise.
