Background
Myopia is classified into true myopia and pseudomyopia. True myopia is divided into refractive myopia and axial myopia. The reason for the refractive myopia is that the lens is always in the high diopter condition under the long-time compression of the ciliary body when the eye is used, so that the diopter adjustment range of the lens is reduced, the object image projection beyond a certain distance can be projected in front of the retina, and the eye can be corrected through the myopia glasses at this time and can be possibly recovered by matching with other training means.
However, in the adolescent period, if the eyes are not standard, the ciliary body is in a tense body for a long time, and the ciliary body not only can press the crystalline lens, but also can press the vitreous body of the eyeball, so that the pressure in the vitreous body of the eyeball is increased, the axis of the eye of the glasses is increased, and the axial myopia is caused. At present, no effective means exists for recovering axial myopia. Therefore, after the glasses are worn for correction, how to prevent and treat the myopia is further deepened is important for the society, the country and scientific research institutions at present.

The corrective adjustment cartridge includes: a first connecting cylinder 3, a second connecting cylinder 1, a variable focus convex lens and a variable focus concave lens. The first connecting cylinder 3 is a cylindrical structure, and one end of the first connecting cylinder is fixedly connected with the fixing structure. The second connecting cylinder 1 is a cylindrical structure, and one end thereof is inserted from the other end of the first connecting cylinder 3 and is slidably connected with the first connecting cylinder 3. The variable-focus concave lens is arranged at one end of the first connecting cylinder 3 close to the fixed structure and is fixedly connected with the first connecting cylinder 3. The variable-focus convex lens is arranged at one end, far away from the first connecting cylinder 3, of the second connecting cylinder 1 and is fixedly connected with the second connecting cylinder.
As shown in fig. 4. Wherein the variable focus concave lens comprises: the lens comprises a first hard plane lens 20, a first transparent soft rubber cake 21, an arc-shaped transparent elastic thin plate 22, a first adjusting ring 19 and a limit snap ring 17. The limiting snap ring 17 is arranged in the first connecting cylinder 3 and is fixedly connected with the inner wall of the first connecting cylinder 3; the first hard planar lens 20 is installed in the limit snap ring 17, and the periphery of the first hard planar lens 20 is fixedly connected with the inner wall of the limit snap ring 17. A first transparent soft gel cake 21 is mounted on one side of the first hard planar lens 20. The arc-shaped transparent elastic sheet 22 is installed at one side of the first transparent soft rubber cake 21. The cambered surface of the arc-shaped transparent elastic sheet 22 faces the first transparent soft rubber cake 21 and is abutted against the first transparent soft rubber cake 21.

One end of the first screw 18 passes through the connecting piece 23 and is in threaded connection with the connecting piece 23, the other end of the first screw 18 is provided with a head, and the head of the first screw 18 is in sliding connection with the connecting piece 23. While the first screw 18 is driven by the driving block. Under the drive of the drive block, the first threaded spindle 18 starts to rotate, and under the action of the first threaded spindle 18, the first adjusting ring 19 starts to contract or expand. The arc-shaped transparent elastic thin plate 22 against the inner wall of the first adjusting ring 19 changes with the change of the first adjusting ring 19, so that the radian is increased or decreased. When the radian of the arc-shaped transparent elastic sheet 22 is increased, the middle part of the first transparent soft rubber cake 21 is pressed to be increased, so that more substances in the first transparent soft rubber cake 21 are filled to the periphery. Thereby increasing the diopter of the variable focal concave lens and reducing the focal length. When the radian is reduced, the periphery of the same arc-shaped transparent thin plate presses and increases the edge of the first transparent soft rubber cake 21, so that the middle of the first transparent soft rubber cake 21 is thickened, the diopter of the variable-focus concave lens is reduced, and the focal length is increased. The limit snap ring 17 is provided with a limit buckle which is pressed against the ring surface of the first adjusting ring 19. The limitation of the movable range of the first adjusting ring 19 can be realized, so that when the arc-shaped transparent elastic thin plate 22 is deformed, the first transparent soft rubber cake 21 can be pressed.
As shown in fig. 3 and 6, among others. The variable focus convex lens comprises: a second adjusting ring, a containing groove, a second hard plane lens 14, a first transparent soft rubber cake 21 and a plane transparent elastic sheet 16.
The second adjusting ring is arranged in the second connecting cylinder 1, and the outer annular wall of the second adjusting ring is fixedly connected with the inner wall of the second connecting cylinder 1. The holding tank is the annular groove of opening on the second adjustable ring inner wall. The second adjusting ring is separated from the position where the receiving groove is located, forming a fixed ring 11 and a moving ring 12. The outer wall of the fixed ring 11 is fixedly connected with the inside of the second connecting cylinder 1, and the outer wall of the movable ring 12 is slidably connected with the inner wall of the second connecting cylinder 1.
Wherein the second hard planar lens 14 is mounted on the fixing ring 11, and the periphery of the second hard planar lens 14 is fixedly connected with the accommodating groove on the fixing ring 11. The second transparent soft adhesive film 15 is installed on one side of the second hard planar lens 14 to contact with the second hard planar lens 14. The plane transparent elastic sheet 16 is installed on one side of the second transparent soft rubber cake 15, contacts with the second transparent soft rubber cake 15, and the periphery of the plane transparent elastic sheet abuts against the accommodating groove of the moving ring 12. The moving ring 12 abuts against the flat transparent elastic sheet 16. Thereby forming a variable focus lens.
Through holes along the axial direction of the second adjusting ring are formed in the ring bodies of the movable ring 12 and the fixed ring 11. An internal thread is arranged in the through hole. A second screw 13 is also arranged in the through hole. The second screw 13 is threadedly coupled to the fixed ring 11 and the moving ring 12. The second screw 13 is driven by the drive block. In use, the driving block drives the second screw 13 to rotate, so that the distance between the moving ring 12 and the fixed ring 11 changes. When the distance between the moving ring 12 and the fixed ring 11 shortens, the moving ring 12 can press the edge of the plane transparent elastic sheet 16, the plane transparent elastic sheet 16 has elasticity, so deformation can occur, at the moment, the inner side of the plane transparent elastic sheet 16 is supported by the second transparent soft rubber cake 15, the pressure on the edge of the second transparent soft rubber cake 15 is greater than the pressure on the middle part, the substances in the second transparent soft rubber cake 15 can change to move the middle part, the pressure on the middle part is increased, and the plane transparent elastic sheet 16 is changed into a convex cambered surface, so that a variable-focus convex lens is formed. When the distance between the fixed ring 11 and the moving ring 12 increases, the transparent elastic sheet 16 has elasticity due to the flat surface. The periphery will begin to recover and the edge pressure of the second clear gum cake 15 will decrease. Thereby causing the material to migrate to the periphery, reducing the pressure in the middle, and causing the curvature of the flat transparent elastic sheet 16 to decrease, even becoming a flat lens.
The correcting cylinder connecting part is positioned between the two correcting adjusting cylinders, and the two side ends of the correcting cylinder connecting part are fixedly connected with the two correcting adjusting cylinders respectively. The correction cylinder connecting portion includes: a first connection 4, a second connection 2 and a third screw 10.

And one end of the second connecting cylinder 1 close to the fixed structure is inserted into one end of the first connecting part 4 far away from the fixed structure and is connected with the first connecting part 4 in a sliding way. One end of the third screw 10 is inserted into the second connection portion 2, and is screwed with the second connection portion 2. The other end of the third screw 10 is inserted into the first connecting portion 4 and rotatably connected to the first connecting portion 4. The third screw 10 is driven by a drive block.
The driving block includes: a correcting cylinder adjusting motor, a convex lens adjusting motor and a concave lens adjusting motor. The correcting cylinder adjusting motor is fixedly installed in the first connecting portion 4, is electrically connected with the control module, and is used for driving the third screw 10. The convex lens adjusting motor is fixedly installed in the second connecting portion 2, electrically connected with the control module, and used for driving the second screw 13. The concave lens adjusting electrode is fixedly installed in the second connection part 2, electrically connected with the control module, and used for driving the first screw 18.
And the auxiliary function module 9 is arranged at one end of the connecting part of the correction cylinder, which is far away from the fixing structure, and is electrically connected with the control module. The specific auxiliary function module 9 is installed at one end of the second connecting part 2 far away from the first connecting part 4, is electrically connected with the control module, and is positioned on the same plane with the two correcting and adjusting cylinders. The auxiliary function block 9 includes: projection lamp, infrared emitter and infrared receiver. The projection lamp is arranged at the end part of the second connecting part 2, is electrically connected with the control module and can project pictures. The infrared emitter is installed at the end of the second connecting part 2 and is electrically connected with the control module. The infrared receiver is installed at the end of the second connecting part 2 and electrically connected with the control module. The infrared transmitter and the infrared receiver may be used to measure the distance between an object being viewed by the wearer and the wearer, thereby better adjusting the distance between the variable focus convex lens and the variable focus concave lens, as well as the diopter of the variable focus convex lens.
This application is through measuring the distance between the person of wearing and the object of looking directly at, automatic to the distance between the convex lens of zooming and the concave lens of zooming and the diopter of the convex lens of zooming for the distance between the formation of image of the concave lens of zooming and the glasses is in the visual scope under the current ciliary body state of wearing, thereby makes the ciliary body of person of wearing be in the state of relaxing as far as, reduces the oppression to crystalline lens and eyeball vitreous body, has realized the purpose that the myopia prevention degree deepens. Besides, the myopia degree of the user can be tested through the handheld remote control terminal.
As shown in fig. 7, where Umax represents the maximum clear visibility of the wearer in the naked eye state, while the wearer's ciliary body is in a relaxed state. Therefore, the principle of the application is that the convex lens changes the object at a far position through the convex lens and the concave lens, so that the image of the concave lens is as close to the Umax position as possible, the ciliary muscle of a wearer is in a relaxed state as much as possible, and the problem that under the condition that the ciliary body is over-tensed, the vitreous body and the crystalline lens are excessively stressed, so that the myopia is deepened is solved.
In addition, the corrector of the application can enable the imaging of the variable-focus concave lens to be as close to Umax as possible by adjusting the variable-focus convex lens and the distance between the variable-focus convex lens and the variable-focus concave lens when a wearer directly views near objects. Since the position of Umax is outside 2f of the variable-focus concave lens, the control module in the present application controls the imaging a' of the variable-focus convex lens to be between f and 2f of the variable-focus concave lens, and at this time, it can be known from the lens imaging principle 1/u +1/v =1/f that the final imaging a ″ of the variable-focus concave lens is outside 2f and is as close to Umax as possible, but does not exceed Umax.
This will allow the wearer to use the orthosis of the present application without the problem of a lack of standard eye use and without fear of increased myopia due to prolonged ciliary muscle tension resulting from too close proximity to the viewing object.
When the wearer needs to measure the myopia degree of the wearer, the mode can be switched through the handheld remote control end. When the myopia degree is measured, the control module can eliminate the diopter of the variable-focus convex lens, so that the variable-focus convex lens becomes a plane lens, and the distance between the wearer and the current direct-view area is measured. The wearer is then reminded to go forward or backward. And then projecting vision measurement pictures in the area where the wearer looks directly through by using a projection lamp.
The wearer can control the diopter of the variable-focus concave lens through the handheld remote control end according to the visual blurring degree and the cleaning degree, so that the myopia degree of the wearer can be known.
Therefore, in order to enable the correction instrument to interact with the wearer better, a loudspeaker can be added to the ear hook 6 to achieve interaction with the wearer. Meanwhile, when the wearer uses the device, the distance data of the direct-view object and the self-measured data can be wirelessly transmitted to any appointed target.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
