A pupillometer (PD meter) is a precision optical device used to measure interpupillary distance (PD) – the space between pupils' centers. Essential for crafting prescription eyewear, it ensures lenses align perfectly with eyes for optimal vision correction. Modern versions employ infrared sensors or digital imaging for millimeter-accurate readings within seconds. Features include monocular/binocular PD measurement, distance/near focusing ranges, and adjustable nose bridges.


Clinicians value its efficiency in optometry practices and optical shops, eliminating manual ruler errors. Some advanced models integrate EHR systems and provide 3D facial measurements. Proper PD measurement prevents eye strain, headaches, and blurred vision caused by incorrect optical centering in glasses. Portable designs now enable home use.
