Abstract
The utility model discloses a kind of interpupillary distance self-testing devices, including round shaft (1), eye touching frame (2), fixed view pipe (3), crosshair (4), jack rod sleeve (5) and slide bar (6)；Described determines view pipe (3) equipped with crosshair (4), and the slide bar (6) is inserted into jack rod sleeve (5) and being capable of opposite sliding.The utility model solves the problems, such as user's introspection interpupillary distance, two sides when two eye sight lines are parallel regard the visual field in pipe surely and are overlapped, it can determine that the scale that instrument is shown at this time is pupil of both eyes distance, have the advantages that easy to use, quick test, measurement result are reliable.
Description
Technical field
The utility model relates to medical instruments fields, specifically be a kind of interpupillary distance self-testing device.
Background technique
A nearsighted person's number is continuously increased both at home and abroad at present, is either still used instrument treatment near-sighted with mirror, is needed mostly
Measure patient's interpupillary distance.Especially when oneself uses myopia instrument, family's conditional be difficult to accurately to measure pupil of both eyes away from
From.Current most of survey interpupillary distance instruments just have at each hospital, optician's shop and optometry center, and it also requires other people assist
Measurement, lacks the household centro meter device of self-service measurement.The myopia instrument of some simple eye pressings, to adjusting pupil on instrument
Away from accuracy requirement it is higher, in the case where not knowing oneself interpupillary distance, the interpupillary distance of random conditioning instrumentation is easy to happen medical thing
Therefore.
Summary of the invention
The technical problem to be solved by the utility model is to provide one kind accurately, safely, conveniently, and user self-service can survey
Measure the interpupillary distance self-testing device of oneself interpupillary distance.
In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of interpupillary distance self-testing device, including circle hand
Handle, eye touching frame, fixed view pipe, crosshair, jack rod sleeve and slide bar, the crosshair are located on fixed view pipe；The circle hand
Two disc indents above and below handle.
The interpupillary distance self-testing device is made of two one-piece parts, in addition to one of them have on the whole slide bar, another
Have other than jack rod sleeve on the whole, remaining component part is identical in two one-piece parts.
The slide bar can be inserted into pull movement in jack rod sleeve, change the size of interpupillary distance parameter on instrument with this.
The crosshair center is equipped with the circular hole of 1mm diameter.
The measurement range of the interpupillary distance ruler is 55mm to 75mm, is equipped in eye touching frame and determines window.
The utility model has the function of user's introspection pupil of both eyes distance, and safe and reliable, measurement result
It is more accurate.Frame is touched by eye to contact with the eye socket of people, guarantees that the crosshair on both sides is equidistant between eyes, and by ten
Word cross hair central small hole makes eyes more accurately eyes front, keeps eyes sight parallel, and interpupillary distance size is finally read from slide bar
Data.Interpupillary distance self-testing device can easily allow user oneself to complete the measurement of interpupillary distance, and test result is accurate and reliable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the inside structure schematic diagram of the utility model.
As shown in the figure, 1, round shaft, 2, eye touch frame, 3, fixed view pipe, 4, crosshair, 5, jack rod sleeve, 6, slide bar, 7, fixed view
Hole, 8, interpupillary distance ruler.
Specific embodiment
The embodiment of the utility model interpupillary distance self-testing device is explained with reference to the accompanying drawing.
As shown in Figure 1, the utility model interpupillary distance self-testing device, including round shaft 1, eye touch frame 2, regard pipe 3 and crosshair surely
4, and the jack rod sleeve 5 and slide bar 6 of the sliding that cooperates.
The eye touching frame 2 is equipped with round shaft 1 and regards pipe 3 surely, and 1 upper and lower surface of round shaft is anti-skidding concave inward structure.
Described determines view pipe 3 equipped with crosshair 4, and the center of crosshair 4 is equipped with the circular hole of 1mm diameter.
Window 7 is determined as shown in Fig. 2, being equipped in the eye touching frame 2, and crosshair 4 limits sight side with window 7 is determined jointly
To.
For the measurement range of the interpupillary distance ruler 8 from 55mm to 75mm, metering method is recessed according to the identical rectangle of spacing
Slot calculates, and the width of rectangular recess is 1mm, and it is scale division value by 1mm that the distance between two neighboring groove boundary, which is also 1mm,
To calculate interpupillary distance size.
Using the eyes of people with tropism principle, which belongs in the binocular balance principle of people the interpupillary distance self-testing device
Coordinated balance.Superior being based on the mankind can just have this biological function.Showing themselves in that for the principle follows eye movement
Criterion, can it is simultaneously very accurate, balance, in concert with move, two are watched attentively forward in parallel, though eyes close or
Person closes wherein one eye eyeball, and two eyeballs still are able to coordinate synchronization, in the same direction movement.Interpupillary distance self-testing device is based on the biological principle
And design: human eye interpupillary distance maximum is only 0.075 meter, when human eye to tens meters so that outside a few kms at a distance look into the distance when, it is double
An eye line approach is parallel, and the angle of deviation is very little, ignores.Thus eyes look into the distance a distant place when in use, after sight is parallel,
The visual field that conditioning instrumentation makes two sides determine to regard in pipe 3 is overlapped, and the interpupillary distance size shown on instrument at this time is tester's interpupillary distance.
When measuring eyes interpupillary distance, user's eyes sight should initially pass through instrument and regard pipe 3 surely the interpupillary distance self-testing device, then
It is seen by 4 center of crosshair to the distant place other than 10 meters, judges whether the crosshair 4 of two sides weighs with eyes remaining light in the visual field
It closes, it, cannot will be on focus vision to crosshair 4 it should be noted that be to be gone to see whether two crosshairs 4 are overlapped with eyes remaining light；
If being overlapped, the interpupillary distance reading on interpupillary distance ruler 8 is the eyes interpupillary distance of user at this time, if not being overlapped, holds two round shafts 1 and takes out
Drawing activity is judged by eyes remaining light, until seeing that two sides crosshair 4 is overlapped with remaining light in the visual field.
The interpupillary distance self-testing device when in use, needs eye sight line passing through circular hole and sees distant place scenery, at this moment eyeball
Focal length be farther away tens meters so that upper km distance, rather than close from eyes in this way several centimetres of seeing circular hole itself away from
From, do not allow eyes focus to crosshair 4 itself this in eyes proximity.
The foregoing is merely the preferable specific embodiments of the utility model, are not limitation of the utility model, tool
Body structure is allowed to vary.All various changes made in the protection scope of the utility model independent claims are at this
In the protection scope of utility model.
