The first nut 73 and the first screw 72 are tightened, realizes the connection of the first prism 21 and the first slide rail 5, and due to
The first spring is provided between one slide rail 5 and the first nut 73, the pretightning force of the first spring enables the first prism 21 relative
Rotated in the first through hole on the first slide rail 5, so that after the backbone protective spectacles that the present embodiment provides in user's wearing, it is real
Swinging for the first prism 21 is showed；
Similarly, the second nut and the second screw are tightened, realizes the connection of the second prism 22 and the second slide rail 6, and due to
Second spring is provided between second slide rail 6 and the second nut, the pretightning force of second spring enables the second prism 22 relative
Rotated in the second through hole on the second slide rail 6, so that after the backbone protective spectacles that the present embodiment provides in user's wearing, it is real
Swinging for the second prism 22 is showed.
The swing angle of the first prism 21 and the second prism 22 is adjusted simultaneously, can realize the first prism 21 and the second prism
22 focusing so that the first prism 21 cause and the first prism 21 corresponding to object and the second prism on the desk seen of eyes
22 cause and the second prism 22 corresponding to object on the desk seen of eyes overlap so that user sees more clearly,
Allow user to produce third dimension and more clear wash rice when seeing object, avoid visual fatigue, dizziness.
Specifically, referring to shown in Fig. 8, Fig. 9 and Figure 10, when the first prism 21 is prism, and the eyes of user
When looking squarely, in the sight of first side 33 and people is generally aligned in the same plane, the light of the object in the plane such as desktop is in the first prism
Plane where refraction route in 21 is parallel with first side 33, that is to say, that and human eye is right against in the first prism 21, and first
Point in the parallel surface in side 33.
Referring to shown in Figure 11 and Figure 12, when the first prism 21 rotates along first through hole, the first face 31 is without face people's
The sight and first side 33 of glasses, i.e. people are not in the same plane, and the light of the object on desktop is in the first prism 21
Refraction route where plane and first side 33 it is not parallel, i.e., human eye is right against in the first prism 21, and the phase of first side 33
To the point in inclined surface.That is, by adjusting rotational angle of first prism 21 along first through hole, eye can be adjusted
Eyeball is right against the width in the visual field on desktop.
It should be noted that entering in 11 and Figure 12, comparative with Fig. 8-Figure 10 in order to strengthen, prism is relative to desktop
Isoplanar position does not change, and change is the eyes of user relative to the position in the first face 31 of prism.
Adjust that the first prism 21 rotates along first through hole and the second prism 22 rotates along the second through hole so that human eye passes through the
The point that the point and human eye that one prism 21 is right against on desktop are right against by the second prism 22 on desktop overlaps, so as to realize first
The focusing of the prism 22 of prism 21 and second.
Preferably, shown in Figure 5, the backbone protective spectacles that the present embodiment provides also includes the first packing ring 75 and the second pad
Circle.Wherein, the first packing ring 75 is arranged between the first turn 74 and the first slide rail 5, and second packing ring is arranged at second spring circle
And second between slide rail 6.
Preferably, it is shown in Figure 3, the present embodiment provide backbone protective spectacles, in addition to the second connector 81 and with

The short transverse rotation connection of 3rd connector 82 and the contiguous block 41 along the glasses.
Alternatively, the 3rd connector 82 can be for example detachably connected with the nose frame on mirror holder 1, such as be connected through a screw thread
Realize.
In summary, the short transverse of second connector 81 and the 3rd connector 82 along the glasses, which rotates, connects
Connect, realize the Level Change of the first prism 21 and the second prism 22 relative to mirror holder 1, so as to adapt to different applicable crowds,
And when user temporarily without using the first prism 21 and the second prism 22 when, by the first prism 21 and the second prism 22 relative to mirror
Frame 1 is flipped up, in use, the first prism 21 and the second prism 22 are downwardly turned over relative to mirror holder 1, so that using more
It is convenient.
The short transverse rotation connection of 3rd connector and the contiguous block 41 along the glasses, realizes regulation people
Eye it can be seen that the plane such as desktop on visual field distance, i.e.,：It can adjust before and after human eye seen on desktop relative to human body
Distance.
It is shown in Figure 7, show the first prism 21 relative to two limit positions of the mirror holder 1 along short transverse in Fig. 7
Put --- the field range of first position and the second place.Wherein, first position is the first prism 21 (or the as shown in Figure 7 A
Two prisms 22) the first face 31 state vertical with the sight of people；The second place is the first prism 21 (or the as shown in Figure 7 B
Two prisms 22) the parallel state of the plane such as the second face and desktop.
Below by taking the first prism 21 as an example, still, the second prism 22 is equally applicable.Fig. 7 B show the second face and desktop
Parallel state, when people is at eye level, human eye it can be seen that in figure B points object, wherein, incident light of the B points in the first prism 21
Angle between line and horizontal plane is first angle b；Fig. 7 A show the first face 31 state vertical with the sight of people, and human eye is put down
Apparent time, human eye it can be seen that in figure A points object, wherein, folder of the A points between the incident ray and horizontal plane of the first prism 21
Angle is second angle a.That is rotated by the first prism 21 relative to the short transverse of mirror holder, can when people is at eye level
See the object between first angle b and second angle a in figure, relative to the visual field distance c of human body be A points and B points on desktop
The distance between.
In summary, user can adjust the first prism 21 and/or the second prism 22 along mirror holder 1 according to being actually needed
The rotational angle of short transverse, to adapt to different viewing angle and viewing distance, so as to be adapted to read, write, it is hand-manipulated,
See the different demand such as computer.
