Accurately measures bifocal placement from the pupil to the lowest point on the eyewire.

Really handy and accurate way to measure bifocal placement. Simply align the top of the cross bar under the patient's pupil and read the lowest point of the eyewire on the scale. For patients with a narrow PD just slide the rule so the scale is at the lowest eyewire  point and the wide crossbar will still remain directly under the pupil for truly accurate readings.

Minimizes miscommunication with the lab. Clear plastic with black scale. Also, great for taking box measurements.  7" long.
