Description
Technical field
This utility model relates to a kind of device of measuring human body interpupillary distance, relates to specifically a kind of centro meter that can measure the subjective interpupillary distance of human eye.
Background technology
Interpupillary distance is exactly the distance between two eye pupil holes, when optometry by detecting between pupil center or detecting this data that obtain of distance between cornea optical reflection point, as an important parameter of making glasses.In the time of preparation glasses, wish that the sight line of human eye can be looked thing by lens optical center.
Prior art has a kind of centro meter, the housing arranging before and after comprising, housing front portion is provided with two people's eye fixation windows, rear portions and is provided with and watches cursor attentively, be provided with a pair of cursor slide that can move left and right at people's eye fixation window and the position watched attentively between cursor in housing, when use, human eye is watched and is watched cursor attentively through people's eye fixation window, measures the distance between cornea optical reflection point by the hairspring of installing on cursor slide.Although existing centro meter can be measured the distance between cornea optical reflection point fast, easily, the distance between cornea optical reflection point or the pupil center of images of left and right eyes that what but existing centro meter conventionally gathered is, do not need those who are investigated to feed back its visual experience and just can detect interpupillary distance, that is to say, the interpupillary distance that existing centro meter is measured is all objective interpupillary distance.
Although existing centro meter is convenient, it only limits to detect the distance between cornea optical reflection point, and can not record the distance (subjective interpupillary distance) between eyes sight line.Distance between the sight line mirror surface site of images of left and right eyes that what subjective interpupillary distance gathered conventionally is, i.e. line-of-sight distance, the interpupillary distance of measuring according to those who are investigated's sensations (having subjective characteristics) when subjective interpupillary distance digital examination, needs those who are investigated to feed back its visual experience and cooperates.Require high Progressive addition lens wearer to wait for some particular patient's for interpupillary distance, existing centro meter can not collect the parameter of the location use of accurate eyeglass optical center, that is to say that existing centro meter can not measure the value of subjective interpupillary distance.
Summary of the invention
The purpose of this utility model is to provide a kind of centro meter that can measure the subjective interpupillary distance of human eye, is beneficial to the more accurate interpupillary distance of control selection, is conducive to improve technology and the quality level of glasses preparation.
This utility model adopts following technical scheme: a kind of centro meter, the housing arranging before and after comprising, housing front portion is provided with two people's eye fixation windows, rear portion is provided with watches cursor attentively, be provided with a pair of cursor slide that can move left and right at people's eye fixation window and the position watched attentively between cursor in housing, on described each cursor slide, be fixed with respectively the brake sack be arrangeding in parallel with people's eye fixation window, on described each brake sack, all offer the vertical gap seeing through for people's an eye line, the position being positioned on described brake sack under vertical gap is painted with a vertical groove, the bottom that is painted with described vertical groove on brake sack is bright zone.
The top that described brake sack offers vertical gap is opacity.
The height of described opacity and bright zone is all no more than 1/2nd of enclosure interior height.
The top that described brake sack offers vertical gap is one-way transparent district, in this one-way transparent district, from people's eye fixation window to the direction of watching cursor attentively be opaque not visible, be transparent visual from watching cursor attentively to the direction of people's eye fixation window.
The height of described one-way transparent district and bright zone is all no more than 1/2nd of enclosure interior height.
The bottom of described brake sack is fixedly connected with and is useful on the L shaped base being arranged on cursor slide, and vertical section of L shaped base is fixed together with brake sack, and horizontal segment and the cursor slide of L shaped base are fixed together.
The length in described vertical gap is that 10mm, width are 1mm.
The beneficial effects of the utility model are: this utility model in use, aiming at cornea optical reflection point with the vertical groove in dark slide measures after detected person's objective interpupillary distance, move down a little centro meter, the top that makes dark slide have vertical gap hides detected person's cornea, move left and right cursor slide, thereby fine setting can be realized in the vertical gap in dark slide on horizontal level, finally make a measured left side, right eye can be seen and watch cursor attentively through the vertical gap in two dark slides respectively, utilize vertical gap to catch and locate sight line, the direction of restriction sight line, thereby measure the site distance of two an eye line.Detected person watches the cursor of watching attentively of centrometer inside attentively by the vertical gap in dark slide, using sight line in the site of spectacle plane the reference point as interpupillary distance parameter acquisition, this utility model can be relatively easy to measure subjective interpupillary distance.
Further, opacity, brake sack top, can prevent that detected person from seeing through region around, vertical gap and seeing and watch cursor attentively, makes measurement result of the present utility model more accurate.
Further, brake sack top is one-way transparent district, and tester not only can see through vertical gap but also can, through vertical gap area observation detected person's around eyes, further improve the degree of accuracy of this utility model measurement result.
Further, L shaped base can very easily be arranged on cursor slide brake sack, makes this utility model simple in structure, easy for installation.
Further, length is that the vertical gap that 10mm, width are 1mm can make people's an eye line see through just, can be relatively easy to see and watch cursor attentively.
