The new EZ View Prism Bar eliminates a problem that exists with other prism bars: the numerical magnitude of the prism has typically been located on the thick edge of the prism bar. This created a problem for the examiner. When using the prism bar to measure either the angle of deviation or to measure convergence and divergence amplitudes, the examiner had to either turn the prism bar sideways to view the numerical magnitude or make a pronounced movement to the side to view the prism magnitude. When moving the position of prism magnitude with EZ View the examiner can now see the numbers without the need to either turn the prism bar or change viewing position. The issue of turning the prism bar sideways during the assessment of vergence amplitudes could interfere with the accuracy of the measurement.
