Detailed description of the invention
Fig. 1 is the structural schematic diagram of wear-type visual function detection device described in the utility model embodiment；
Fig. 2 is the usage state diagram of wear-type visual function detection device described in the utility model embodiment.
In figure: 1, VR head-wearing device；2, ultramagnifier；3, photographic device；4, light source；5, eyeglass.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is a part of the embodiment of the utility model, instead of all the embodiments.Based on the reality in the utility model
Apply example, those of ordinary skill in the art's every other embodiment obtained without making creative work, all
Belong to the range of the utility model protection.
As depicted in figs. 1 and 2, a kind of wear-type visual function detection device provided by the embodiment of the utility model, including VR
Head-wearing device 1 and ultramagnifier 2, the VR head-wearing device 1 is for providing closed visual-field space；
The VR head-wearing device 1 includes: photographic device 3, memory, processor and built-in display, the processor
It being connect respectively with the photographic device 3, memory, display, the photographic device 3 is used to shoot the eyeball image of subject,
The memory detects examination question for storing the eyeball image and visual function, and the display is used in the visual-field space
Show that visual function detects examination question, the processor is used to handle the eyeball image state to judge current eye；
The ultramagnifier 2 is connected to the processor, and the ultramagnifier 2 is examined for feeding back subject for current visual function
The result of test question selection.
Display is built in VR head-wearing device 1, after subject wears, the opposite position between display and subject's eyeball
It sets and remains unchanged, subject can arbitrarily walk about, sit down or stand during the test, not limited by place, without protecting for a long time
An anchor is held, is not easy to feel sleepy；VR head-wearing device 1 can provide a closed visual-field space simultaneously for subject, outside
Boundary's light cannot be introduced into, and test process is not by external light influence；In conjunction with ultramagnifier 2, subject can be by it to current visual function
The answer feedback of examination question is detected to processor, realizes independent progress visual function detection, it is lower to the degree of dependence of doctor；It is existing
1 buying expenses of VR head-wearing device of built-in display are in thousands of members or so, for existing import equipment, buying at
Originally it declines to a great extent, outpatient service, small hospital, even subject itself can bear this price, convenient for promoting；It is testing simultaneously
After still can be used as the use of VR head-wearing device 1, for example see 3D film, play game etc., VR head-wearing device 1 itself can be equipped with control
Device not will cause waste without individually purchase when test；Photographic device 3 can be with the eyeball state of captured in real-time subject, and incites somebody to action
Picture issues processor, and processor compares peer to peer technology using existing picture recognition, picture, it can be determined that the shape of current eye
State, such as: it opens eyes, close one's eyes, eyeball pays close attention to direction etc..
When specific test, such as test left vision, then the region for corresponding to left eye over the display shows " E " word, is examined
Person judges the opening direction of " E ", and presses the key of corresponding direction on ultramagnifier 2, completes feedback；Processor is according to feedback result
Correctness determine the contents of next test pictures；When field range detects, image that processor is shot according to photographic device 3
Judge the central point whether current eyeball shows on concern display, be not concerned with, stops showing random test point, close again
Continue to show test point after note central point；Test process so is just not necessarily to doctor and pays close attention in real time, entire test process can by by
Inspection person oneself complete independently；Meanwhile when for one of Eye testing, subject grasps without deliberately blocking another eye
It is more convenient.
Preferably, which further includes the control unit being connected to the processor.Control is single
Member is mainly used for the setting of test parameter and the typing of subject's personal information, is mainly joined by doctor or nurse in the subject
It is operated with before test, certain subject can also carry out oneself typing；It is adjusted when in this way in test process if necessary to zero
Setting, does not need to remove VR head-wearing device 1 yet, and doctor can directly be configured or data inputting, and subject is without taking VR head
Device 1 is worn, the testing time is saved.It is aobvious that control unit may is that mobile phone, tablet computer, laptop, desktop computer etc. have
The input terminal of display screen also may include medical insurance card, identity card, reading device of medical card etc., fast and easy typing subject
Personal information.
Preferably, the photographic device 3 is infrared camera.Infrared light is black light, and subject experiences not at all
It is stimulated to light, guarantees shooting effect.
Preferably, the photographic device 3 is equipped with light source 4.When photographic device 3 is infrared camera, light source 4 is also used
Infrared light supply, to obtain the eyeball image being more clear.When photographic device 3 is visible image capturing head, light source 4 is visible light
Light source, in order to reduce stimulation of the light source 4 to eyeball, it is preferred to use LED light source, and the lower dim light of intensity of illumination is used, to the greatest extent
Amount reduces the stimulation to eyeball, guarantees the effect of visual function detection.
Preferably, the ultramagnifier 2 is control handle.General VR head-wearing device 1 can be equipped with control handle in purchase,
Therefore without independent purchase, as long as buying a VR head-wearing device 1, so that it may carry out visual function detection, this expense one
As family also can easily receive, needless to say community clinic and hospital.
Preferably, the control handle is connect with the processor by infrared ray, bluetooth or cable.Infrared ray, bluetooth
Deng wireless connection as shown in Fig. 2, subject's operation is unrestricted；Cable connection is as shown in Figure 1, signal transmission is more stable.
Preferably, as shown in Figure 1, the VR head-wearing device 1 further include setting the display and subject's eyeball it
Between two pieces of eyeglasses 5, the corresponding right and left eyes setting of two pieces of eyeglasses 5, the distance between two pieces of eyeglasses 5 is adjustable.Subject passes through eyeglass 5
The picture that viewing display is shown；The interpupillary distance of different subjects has difference, by the fine tuning of this adjustment structure, is adapted to not
Same subject avoids impacting testing result.Certainly preferably two pieces of eyeglasses 5 are adjusted in synchronism, to guarantee in two pieces of eyeglasses 5
Heart position remains unchanged.
Preferably, the display between two pieces of eyeglasses 5 at a distance from be adjusted.Eyeglass 5 is located at eyeball and display
Between, when adjusting, the front-rear position of adjustable display, the also front-rear position of adjustable eyeglass 5, it is certainly preferred adjust it is aobvious
Show the position of device, in order to avoid the phenomenon that causing user not see because of the position for adjusting eyeglass 5, when shortening spent by adjusting
Between.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that:
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement；And these are modified or replaceed, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
