The most common instrument called a pupilometer measure the PD, or pupillary distance for fitting the optic centers of eyeglasses. The dual nomenclature can't be dismissed, though I don't see any references. I would include this instrument in the Category:Ophthalmic_equipment, but the article is written otherwise.

Please add: A pupilometer should be used rather than a ruler on the nose for progressive lenses because even a tiny error causes an out-of-focus image. Sponsion (talk) 02:20, 24 February 2009 (UTC)

Pupilometer - Measures the distance between the pupils
The Interpupillary distance and the pupilometer should be removed, the title to this be changed to Pupillometry and a Corneal Reflex Pupilometer Page be started (OpticianCarrie (talk) 06:52, 24 February 2023 (UTC)
