[0029] The following describes the specific embodiments of the present invention with reference to the accompanying drawings.

[0030] As shown in the attached Figure 1 and 2As shown in the figure, a treatment device for improving and restoring eyesight includes a support body 1, an outer lens 2, an inner lens 3, a driving unit, a limiting unit, and a control unit. The control unit is used to receive signals from the limiting unit and control the operation of the driving unit. Both ends of the support body 1 are connected to temple arms for wearing. The outer lens 2 is fixed to the front of the support body 1. The outer lens 2 has two left and right lens parts, corresponding to the left and right eyes of the user respectively. A nose pad (not shown in the figure) can be provided in the middle of the two left and right lens parts of the outer lens 2 to improve the wearing comfort and stability. The driving unit is fixed inside the support body 1, and the driving unit drives the inner lens 3 to move left and right relative to the outer lens 2. Combining with the attached Figure 2 and 4 As shown, driving units, limiting units, and inner lenses 3 are respectively provided corresponding to the two left and right lens parts of the outer lens 2.

[0031] Preferably, both the outer lens 2 and the inner lens 3 are refractive zoom lenses, and the zoom degree range is from +15.0D to -15.0D (i.e., +1500 degrees to -1500 degrees). Its zoom degree is the same in the up and down direction of the lens and evenly distributed in the left and right direction. The zoom degree x corresponding to each 1mm in the left and right direction is determined by the design of the lens. Further, the zoom degree x corresponding to each 1mm in the left and right direction is preferably 50 degrees; among them, the zoom degree of the outer lens 2 increases gradually from the center position of the support body 1 to the outside direction, that is, the zoom degree range is from -15.0D to +15.0D; the zoom degree of the inner lens 3 decreases gradually from the center position of the support body 1 to the outside direction, that is, the degree range is from +15.0D to -15.0D. And the two left and right parts of the outer lens 2 and the two inner lenses 3 are evenly distributed with equal-difference zoom refractive degrees in the vertical direction centered on the interpupillary distance, so that the pupil distance positions of the two parts of the outer lens 2 and the two inner lenses 3 are aligned; thus, the two parts of the outer lens 2 and the two inner lenses 3 form two groups of progressive zoom lens groups.

[0032] The driving unit includes a moving motor 41, a lead screw 42, and a slider 43. The lead screw 42 is fixedly connected to the output shaft of the moving motor 41, the slider 43 is threadedly connected to the lead screw 42, and the inner lens 3 is fixedly connected to the slider 43. The connection manner between the slider 43 and the inner lens 3 can be that a lens frame is integrally formed below the slider 43, and the inner lens 3 is embedded in the lens frame. During operation, the control unit controls the operating speed of the moving motor 41 to drive the rotation of the lead screw 42, thereby driving the slider 43 to move at different speeds. The slider 43 drives the inner lens 3 to move left and right relative to the outer lens 2, so that the varifocal refractive power generated by the outer lens 2 and the inner lens 3 at the pupillary distance position changes within a certain range. When worn, the relative movement of the inner lens 3 with respect to the outer lens 2 produces a continuous effect of different wearing lens powers, causing the imaging focus to fall within the anterior and posterior intervals of the user's retinal papilla, resulting in a continuous and repeated uniform change of positive focus and negative defocus on the retinal papilla. In this training method, the purpose of improving eyesight is achieved.

[0033] Refer to the attached Figure 5 As shown, an assembly space is formed inside the support body 1. Fixed slots 11 are provided on both sides inside the assembly space. The end face of the fixed slot 11 close to the middle of the support body 1 is provided with a U-shaped U-shaped notch 111. The structure of this U-shaped notch 111 is used for making way. After the moving motor 41 is connected to the lead screw 42, the moving motor 41 can be directly embedded in the fixed slot 11, so that the output shaft of the moving motor 41 is correspondingly embedded in the U-shaped notch 111. The support body 1 is also fixedly connected with a rear sealing plate 6. The rear sealing plate 6 is used to seal the assembly space of the support body 1, and after the rear sealing plate 6 is fixed, the moving motor 41 is pressed and fixed in the fixed slot 11. The connection manner between the rear sealing plate 6 and the support body 1 can be fixed by the way of screwing and installing screws 62. Specifically, the screws 62 can be connected to the upper and lower surfaces at both ends of the support body 1. It can be seen that the present invention can facilitate the assembly of the driving unit by providing the structure of the fixed slot 11 and the U-shaped notch 111 in the support body 1. Further, a rubber pad can be pasted in the fixed slot 11 or on the surface of the moving motor 41. The rubber pad plays a shock-absorbing role to reduce the discomfort caused by the vibration of the moving motor 41.

[0034] Refer to the attached Figure 2 、 6As shown in FIGS. 7 and 8, the driving unit further includes a fixing base 44. A rotating hole 442 is provided on the side of the fixing base 44, and two first threaded holes 441 are provided on the front of the fixing base 44. Two screws 45 are threadedly connected to the two first threaded holes 441. During assembly, after the two moving motors 41 both fix the lead screws 42, the ends of the two lead screws 42 are respectively sleeved in the rotating holes 442 on both sides of the fixing base 44; then the two moving motors 41 are correspondingly embedded in the fixing grooves 11 on both sides of the assembly space, and the first threaded holes 441 of the fixing base 44 face the outer lens 2; finally, the screw 45 passes through the outer lens 2 and the support body 1 into the assembly space and is screwed to the fixing base 44 until tightened, thus completing the fixed connection between the outer lens 2 and the support body 1, and the fixing of the driving unit and the fixing base 44. Through the fixing of this fixing base 44, the other end of the lead screw 42 relative to the moving motor 41 can be effectively supported, avoiding its suspension and affecting the moving path of the slider 43. From the above assembly method, it can be seen that the structure of the fixing base 44 provided by the present invention enables the whole driving unit to be assembled outside the assembly space and then embedded into the assembly space, which can further facilitate the assembly of the driving unit.

[0035] Referring again to the attached Figure 5 figures, a notch 13 is provided at the lower end of the support body 1 in the assembly space. Referring to the attached Figure 8 figures, a retaining piece 61 is provided at the bottom of the rear sealing plate 6 and is embedded in the notch 13. After the rear sealing plate 6 is fixedly connected to the support body 1, the retaining piece 61 is embedded in the notch 13, and a gap formed between the retaining piece 61 and the notch 13 is a moving hole 14. The slider 43 passes through the relief hole 14, and the slider 43 is restricted by the relief hole 41 and moves along the length direction of the moving hole 14. During assembly, when assembling the driving unit according to the above assembly method, it is only necessary to, as shown in the attached Figure 6 figures, abut the slider 43 against the notch 13.

[0036] Referring again to the attached Figure 2 and 3 , the limiting unit includes a limiting plate 51, a limiting button 52 and an adjusting screw 53. The limiting button 52 can be a travel switch. The limiting button 52 is fixed to the limiting plate 51, and the contact of the limiting button 522 faces the slider 43. A second threaded hole is provided at the top of the limiting plate 51, and a strip-shaped adjusting hole 12 is provided at the top of the support body 1. The limiting button 52 is located in the assembly space and makes the limiting button 52 correspond to the side of the inner lens 3. Specifically, as shown in the attached Figure 3 and 7As shown, the limit plate 51 is also provided with a through relief hole 511, and the lead screw 42 of the driving unit passes through the relief hole 511. A connecting rod 54 is fixed to the top of the limit plate 51, and the second threaded hole is provided at the upper end of the connecting rod 54. When the inner lens 3 moves to trigger the contact of the limit button 52 by the slider 43, the control unit receives this signal of the limit button 52 and controls the driving unit to drive the inner lens 3 to move in the opposite direction. Thus, it can be seen that the limit units are arranged on both sides of the slider 43 to enable the inner lens 3 to reciprocally move between the limit plates 51 of the two limit units.

[0037] Referring again to the attached Figures 6 to 8 , the adjusting screw 53 passes through the adjusting hole 12 from outside the support body 1 and is threadedly connected to the second threaded hole at the top of the limit plate 51 until it is tightened. Thus, it can be known that when the adjusting screw 53 is loosened, the limit plate 51 can be pushed to move along the length direction of the adjusting hole 12, which is equivalent to adjusting the position of the limit plate 51 in the assembly space to limit the left - right movement range of the slider 43 and the inner lens 3, thereby realizing manual adjustment of the movement range of the inner lens 3. Further, a scale can be provided on the side of the adjusting hole on the support body to facilitate reference by the adjusting screw 53, so as to adjust the appropriate movement range of the inner lens 3.

[0038] In addition, continuing to refer to the attached Figure 9 shown, preferably, the control unit can establish a wireless signal connection with the intelligent device through the built - in wireless communication module, enabling information interaction and intelligent control between the treatment device of the present invention and the intelligent device held by the user. The specific implementation method is as follows:

[0039] The control unit is provided with a main control module, a wireless communication module, and a driving module. The main control module internally stores the zoom degree x value corresponding to each 1 mm of each lens in the inner lens 3 and the outer lens 2, enabling the main control module to adjust and control the zoom degree and zoom speed of the lens 2 according to the correction degree and training intensity sent by the user. The wireless communication module is bidirectionally signal - electrically connected to the main control module, and the driving module is electrically connected to the main control module; both of the moving motors 41 are electrically connected to the driving module, enabling the driving module to control the corresponding moving motor 41 to work according to the instructions of the main control module.

[0040] The wireless communication module is also used to establish a signal connection with the user's smart device, so as to realize the information interaction between the main control module on the control unit and the smart device. The smart device is a device such as a mobile phone or a computer with a relevant APP installed. When in use, the user can send the user's current correction degree and the intensity of this training to the main control module on the control unit through the APP of the smart device. After adopting the above intelligent interaction method, the present invention can send the correction degree of the user's left eye and / or right eye in this time to the main control module of the control unit through the APP built in the smart device. The main control module of the control unit converts the received correction degree into the left-right displacement distances of the two parts of the two inner lenses 3 relative to the outer lens 2, and controls the moving motor 41 to drive the inner lens 3 to move to the target position according to the converted displacement distance, so as to complete automatic focusing, that is, the focal points of the optical visual paths of the user's left eye and / or right eye respectively fall on the retinal papillae, which is equivalent to making the optical visual paths of the user's left and right eyes respectively in the ortho-focus position. The main control module takes this target position as the central axis of the left-right movement of this training. At the same time, the left-right correction degree range of ±300 degrees of the central axis (the positions corresponding to ±300 degrees are the positive defocus and negative defocus positions of the user's vision) is used as the moving range of the two inner lenses 3 in this training. The main control module converts the left-right correction degree range of ±300 degrees into the left-right movement distance according to the degree x corresponding to each 1 mm of the lens 2 (built in the main control module), which is used for the driving control of the two inner lenses 3 by the driving unit. The control unit controls the driving unit to drive the inner lens 3 to make a left-right uniform displacement movement at a determined speed within the determined range with its central axis as the reference according to the determined moving range and the determined training intensity (that is, the moving speed of the inner lens 3 relative to the outer lens 2), so as to produce continuous different wearing lens degree effects, and achieve the purpose of training and improving eyesight.

[0041] To sum up, the present invention consists of a support body 1, an outer lens 2 and an inner lens 3 to form the main body of the device, making the whole form the structure of a pair of glasses, which is easy to wear and convenient to use. When in training use, by controlling the operating state of the driving unit through the control unit, the driving unit drives the inner lens 3 to move relative to the outer lens 2, so as to produce continuous different wearing lens degree effects, making the focal point of the image fall in the front and back intervals of the user's retinal papilla, and generating continuous and repeated uniform changes of positive defocus and negative defocus on the retinal papilla, so as to achieve the purpose of improving or restoring eyesight. And by adjusting the position of the limiting unit, the user can be specifically trained for eyesight, which can greatly improve its applicability and use effect compared with the current eye treatment devices.

[0042] The above is only the specific implementation manner of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantive modification made to the present invention using this concept shall fall within the scope of infringement of the protection of the present invention.
