Abstract：  Through the brief introduction of JJF1996-2022“Calibration specification of pupilometer verification device”， the merits and limitations of using projectors and image measuring instrument to measure the measurement parameters of pupilometer verification device are discussed. Specifically， this paper analyzes the difference between the measurement terms of the left-right asymmetry deviation and the left-right pupil distance of the standard sleeve. Based on this analysis， the paper recommends the inclusion of a new measurement characteristic： "the consistency of center distance measurement results." This addition aims to enhance the accuracy and reliability of pupilometer distance meter verification.

Key Words： Pupilometer distance meter verification devices; Left-right pupil distance deviation; Consistency of center distance measurements
