Person, it is necessary to consider this parameter when getting the right lensses for one's eyeglasses.The distance (optical center distance) of i.e. two pieces center of lens should be with the pupil of patient
Away from being engaged, otherwise, even if the number of degrees are correct, patient also has uncomfortable sensation after putting on one's glasses, and affects vision.
Under being in normal physiological condition in two eye pupil holes, the following two methods of generally use measure：From pupil of right eye
Central point is the distance between to pupil of left eye midpoint；From pupil of right eye outer rim (temporo side) to pupil of left eye inner edge (nasal side)
Distance；Or distance the outer rim (temporo side) from pupil of right eye inner edge (nasal side) to pupil of left eye.
Closely it is with measuring method：(1) the distance that examiner is separated by 40cm with patient keeps the sight of two people just in face of seat
In sustained height.(2) examiner holds interpupillary distance ruler or ruler with right hand thumb and forefinger, remaining finger leans against the cheek of patient
On, then interpupillary distance ruler is placed at bridge of the nose minimum point, and along bridge of the nose angle slightly inclined.(3) examiner closes right eye, and order is suffered from
Two eye fixation left eye of person is watched attentively with left eye by the pupil center of " zero-bit " alignment patient's right eye of interpupillary distance ruler.(4) examiner opens
Right eye still makes patient continue to watch left eye attentively, and the supercentral numerical value of patient's pupil of left eye is read with right eye.(5) step is repeated
(3) rapid is closely to use interpupillary distance to its average value (4) three times, is taken.
Existing centro meter is although convenient, but principle and structure are all very complicated, in use, needing operator to aid in
Measurement process is completed, cost and efficiency significantly improve.
