Description

The V aperture mirror

Technical field:

The utility model relates to the optometric technology field, refers in particular to a kind of V aperture mirror.

Background technology:

The maximum reason that myopia produces is heredity and sees that near thing (as see TV, see computer, reading, the word that looks at the blackboard) too for a long time and excess eye-using fatigue in the bad classroom of light.When the teenager sees near thing, crystalline lens in the eyeball and ciliary muscle are in tense situation, see that fatigue is not taken a good rest long afterwards, and crystalline lens and ciliary muscle are not yet got back to resting state in tense situation when looking far into the distance, in the course of time just cause pseudo-myopia and low myopia, the long sight ability drop.Pseudo-myopia and low myopia essence are lenticular " preliminary deformation " in the eyeball, at this moment crystalline lens also has very big elasticity, suitably have a rest and try every possible means and adjust, " preliminary deformation " is resilient, wear spectacles and be with the eyeglass diopter and yield to lenticular " preliminary deformation " in the eyeball, in fact no matter true and false property myopia has all become very myopia because of wearing spectacles at last, this is not give " preliminary deformation " restorable chance, and eyeball just really has been out of shape.

Obtain prevention and Micropole glasses occurred in order to make the myopia eyesight obtain correction, particularly teenage pseudomyopia, when wearing Micropole glasses and seeing near thing, because of the pinhole imaging system principle allows crystalline lens and ciliary muscle in the eyeball be in resting state, avoided excess eye-using, the generation of disease capable of preventing myopia; And the pinhole imaging system principle allows crystalline lens in the eyeball and ciliary muscle be in to force resting state, and slight myopia can slowly be corrected (if the crystalline lens in the eyeball also has plasticity, not sclerosis).Particularly pseudomyopia needs most the crystalline lens ciliary muscle that allows in the eyeball and also is in the pressure resting state, helps to recover twenty-twenty vision, and the crystalline lens in the eyeball recovers from distortion.Suitably use Micropole glasses a period of time every day, as see TV, with computer or read a book one hour, just can play pre-myopia prevention effect.

Existing Micropole glasses is to be made of common spectacles frame dress plastic opaque eyeglass, respectively have a plurality of apertures on two glass lens, this Micropole glasses that has a plurality of apertures has following deficiency: the centre distance of aperture can not be when each user sees object the interpupillary distance of two eyes consistent, the interpupillary distance difference of everyone two eyes, the interpupillary distance of two eyes was different again when same individual saw far away or near object, the centre distance of two apertures that this just need be able to regulate, otherwise the user puts on the back or does not see object, see that object has dual shadow, practical requirement not, practicality is not strong.

The patent No. is: the patent of ZL200720059089.4 is a kind of fine adjustment type pin hole mirror of applicant's 2007 inventions, though solved the problem of fine setting, because its related accessory precision is too high, the manufacturing cost height, product can't be promoted in masses preferably.

Auxiliary window area at described eyeglass offers pin hole, and the mean value of the centre distance of the nearest pin hole of each aperture and auxiliary form middle distance in the main viewfinder is greater than the centre distance mean value of adjacent pin hole in the auxiliary form.

Aperture on each eyeglass main viewfinder zone is at least three.

The utility model beneficial effect is: the V aperture mirror, comprise mirror holder, two lighttight eyeglasses, described eyeglass comprises main viewfinder zone and auxiliary window area, the main viewfinder zone of two eyeglasses respectively offers row's aperture from top to bottom, the V-shaped arrangement of stenopeic spectacle picture symmetry on two eyeglasses, auxiliary window area at eyeglass offers pin hole, the mean value of the centre distance of the nearest pin hole of each aperture and auxiliary form middle distance in the main viewfinder, centre distance mean value greater than adjacent pin hole in the auxiliary form, by above-mentioned setting, can satisfy the requirement of seeing Qingyuan City and near object when make using the utility model to greatest extent, can not produce ghost image, and simple in structure, low manufacturing cost is applied easily.

Description of drawings:

Accompanying drawing 1 is the structural representation of the utility model scheme one;

Accompanying drawing 2 is structural representations of the utility model scheme two;

Accompanying drawing 3 is structural representations of the utility model scheme three.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described, see that accompanying drawing 1 is to accompanying drawing 3, the V aperture mirror, comprise mirror holder 1, two lighttight eyeglasses 2, eyeglass comprises main viewfinder 3 zone and auxiliary form 4 zones, main viewfinder 3 zones of two eyeglasses 2 respectively offer row's aperture 5 from top to bottom, the V-shaped arrangement of aperture 5 mirror images symmetry on two eyeglasses 2, auxiliary form 4 zones at described eyeglass 2 offer pin hole 6, the mean value of the centre distance of the nearest pin hole 6 of each aperture 5 and auxiliary form 4 middle distances in the main viewfinder 3, greater than the centre distance mean value of adjacent pin hole 6 in the auxiliary form 4, the aperture 5 on each eyeglass 2 main viewfinders 3 zone is at least three.

The centre distance of the effective aperture 5 of three couples that has at least on the main viewfinder 3 on the eyeglass 2, its purposes is: see five meters and above remote object such as outdoor look far into the distance and indoor on class, the distance at the oculopupillary center, the left and right sides of this moment is maximum, is interpupillary distance; See one meter to five meters distance, as see TV etc. that the distance at the oculopupillary center, the left and right sides of this moment reduces than interpupillary distance.Everyone difference; See the distance of a chi to a meter, as operation or watch computer, digital display device and reading, write, play mobile phone etc., the distance at the oculopupillary center, the left and right sides of this moment is littler.

The aperture 5 of eyeglass main viewfinder 3 roughly becomes V-type to arrange, and according to principle is: the people who generally wears glasses is when seeing distant objects, and the intersection point of sight line center line and eyeglass 2 is partial to eyeglass 2 tops; When seeing near objects, the intersection point of sight line and eyeglass 2 deflection eyeglass 2 belows, the slip of this sight line is unconscious, habitually.On eyeglass 2, pass and a pair ofly see that with the someone 5 meters and above right and left eyes interpupillary distance (interpupillary distance) during apart from object are the hole A of centre distance; As shown in Figure 1, interpupillary distance (littler than interpupillary distance) is pair of holes C or the D or the E of centre distance when seeing written word, on the center line of A point and C (D or E) point, find out B (C again, D) pass onesize aperture 5 again, will see that so the aperture 5 of the needed eyeball centre distance of the object correspondence of any distance has all had.

Because everyone interpupillary distance is different; In fact the aperture 5 that can do the symmetrical holes of a plurality of horizontal range gradual changes just can satisfy everyone requirement of different interpupillary distances and same individual sees far away and two variations that interpupillary distance can take place when seeing near object; As shown in Figure 1, the aperture of arranging in order in the main viewfinder 35 is V-type shape roughly wide at the top and narrow at the bottom with the mirror image center line of symmetrical holes, and straight line AE and perpendicular line have angle, 30 degree〉angle〉5 degree; B, C, each center, hole of D and straight line AE, horizontal range≤1.0MM.

Exemplify four kinds of design proposals of the present utility model below:

One, the design proposal of one group of a plurality of interpupillary distance of V shaped hole:

As shown in Figure 1, the aperture group that in main viewfinder 3 zones, has the 5 one-tenth V-types of aperture more than three pairs to arrange from top to bottom, hole A, B, C, D, E, everyone needs effective aperture 5 of three pairs of continuous adjacent at least, and every pair of uniform phase difference of adjacent aperture 5 horizontal centre distance is a.

With A, B, C are three pairs of apertures 5 that a group effectively uses, and the people that suitable interpupillary distance is approximately A-A uses;

With B, C, D are three pairs of apertures 5 that a group effectively uses, and the people that suitable interpupillary distance is approximately B-B uses;

With C, D, E are three pairs of apertures 5 that a group effectively uses, and the people that suitable interpupillary distance is approximately C-C uses.

This programme, cost is low and to promote simply be great advantage, but user's comfort level is slightly poor.

Two, interpupillary distance of one group of V shaped hole;

(eyeglass 2 pack into mirror holder 1 back) as shown in Figure 2, in main viewfinder 3, have from top to bottom more than three pairs about become in the aperture 5 that V-type arranges, allow A, two pairs of apertures 5 of B, perhaps more, horizontal range is all the same, all equals someone's interpupillary distance; Also there are at least three pairs of apertures 5 to adapt on the V-type line and see more than five meters and the object of following variant line-of-sight distance.This eyeglass 2 that just needs different interpupillary distance designs adapts to different people.

This programme manufacturing cost is higher, and in that to promote difficulty big slightly, need distinguish the specification of eyeglass 2 by interpupillary distance, and the specification of eyeglass 2 will be how surplus in the of ten times, and user's comfort level can be fine.

Three, V aperture mirror sheet 2 and mirror holder 1 all have the eyeglass 2 of the mounting hole site of regulating interpupillary distance;

(eyeglass 2 pack into mirror holder 1 back) as shown in Figure 3 only Duo the adjusting interpupillary distance and the mounting structure corresponding with mirror holder 1 than the 2nd kind of scheme on the V aperture mirror sheet 2.

But this programme can be to everyone different interpupillary distance in-site measurement and installation, and the tube folk prescription of applying is just identical with scheme one, but needs special Private Eye mirror holder 1, and cost is the highest.But user's comfort level is fine, and is identical with scheme two, and the specification of eyeglass 2 need not distinguished according to pupil.

Four, this programme is the method that the interpupillary distance in the scheme three is regulated, and the patent No. of request for utilization people invention is a fine adjustment type patented technology related in the ZL200720059089.4, with this can realize to eyeglass 2 the stepless slip of horizon glass picture symmetry regulate interpupillary distance.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, its framework form can be flexible and changeable, can the subseries product.Just make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
