So much better than a PD stick!
The Manual Pupilometer is the quick way to take accurate measurements of a patient's monocular and binocular interpupillary distance (PD). The higher the prescribed lens power, the greater the need for precise PD measuring. Reduces costly do-overs due to inaccurate measuring. Keep one on hand as backup when your digital pupilometer is non-functional.
All polycarbonate construction. Comes with easy-to-follow instructions. Made in USA.
