1. Introduction
1.1 Uses
Principle: The pupilometer takes the advantage of the image-forming
principle of optical lens. Optical lens imprints the observed object at
a specified distance, then the patient watches at the observed object,
and the optometrist can find out the bright points of the observer’s
eyes via the measuring window, meanwhile the optometrist moves
the left and right measuring keys to make the related mechanical
hairsprings to coincide with the bright points of the observer’s eyes,
so as to measure the distance of the pupils.
Intended use: To measure the distance between the pupils of the
human eye.
Medical purpose: To measure the distance between the pupils of the
human eye.
Target groups of patients: adults, children.
Contact with human body parts
：
Nose and forehead.
Intended users: optometrists in hospital ophthalmology and optical
shops.
Specific qualifications of device users and/or other persons: have a
qualification certificate for optometry and glasses.
Contraindications: none.
