Abstract

The invention discloses a pupil distance measurement device which comprises a target object, two needle hole pieces and a driver. The driver drives the needle hole pieces to move in the horizontal direction. The pupil distance measurement device can accurately measure a pupil distance and can remotely control measurement, and the pupil distance can be measured even if an optometrist is not in a site.

Description

technical field [0001] The invention relates to the field of optometry, in particular to a device and method for measuring interpupillary distance. Background technique [0002] Existing pupillary distance measurements include the following steps: [0003] (1) The examiner and the patient are facing each other with a distance of 40cm, so that the eyes of the two are kept at the same height. [0004] (2) The examiner holds the pupillary ruler or ruler with the right thumb and index finger, rests the other fingers against the patient's cheek, and then places the pupillary ruler at the lowest point of the bridge of the nose, and tilts slightly along the angle of the bridge of the nose. [0005] (3) The examiner closes the right eye, and makes the patient's right eye look at the examiner's left eye. When the left eye is looking at the patient's right eye, the examiner aligns the "zero position" of the pupillary distance ruler with the pupil center of the patient's right eye. ...
