What is the term for the distance between the centers of the pupils, whether in distance or near positions?

The term "Pupillary Distance" refers specifically to the measurement of the distance between the centers of the pupils. This measurement is crucial in optometry as it helps to ensure that optical lenses are properly centered in relation to the eyes, providing the best visual clarity and comfort for the patient. Accurate pupillary distance is essential for correctly fitting glasses or lenses and plays a vital role in personalized vision care.

The other options do not accurately describe this specific measurement. "Papillary Distance" seems to be a misspelling or confusion with the correct term and does not hold relevance in the context of eye care. "Pupil Interspace" is not a standard term used in optometry and could cause misunderstanding as it is not widely recognized. "Pupillary Range" is also misleading as it implies a range rather than a specific measurement, which does not align with the intended meaning of the distance between the pupils.
