Optec 2000-253 Far-Point Vertical Phoria Slide

The Stereo Optical 2000-253 is an individual far-point vertical-phoria slide designed to evaluate vertical alignment between the eyes. The patient compares a horizontal reference line with a numbered stepped scale to identify the perceived alignment position.
