Official English notes
These medical devices measure the distance between the left and right pupil (PD) and are typically used for eyeglass fittings; specifically, to ensure that the eyeglass lenses are centered in the visual axis. Commonly spelled with one 'l' as 'pupilometers,' these medical devices are also known as 'interpupillometers'.
