The Digital PD Meter is an Essilor-style digital pupilometer that reads interpupillary distance right on a digital display — right eye, left eye, and combined — accurate to within 0.25 mm. Built for dispensing opticians and optical labs that need fast, repeatable PD for accurate lens fitting, it measures both monocular and binocular PD and can also gauge the distance from the cornea to lenses or frames.
