Description

Technical Field

[0001] This invention relates to the field of vision correction and visual function training technology, specifically to a multi-region adjustable vision repair device based on the principle of differential surface imaging and its usage method. Background Technology

[0002] Currently, conventional solutions for refractive errors such as myopia, hyperopia, astigmatism, and presbyopia still primarily rely on eyeglasses, contact lenses, and various corneal refractive surgeries. The basic idea behind these techniques is to alter the refractive power of the lens, causing light rays from objects at different distances to refocus on the retina, thereby achieving a "clear image." While they have achieved significant success in correcting overall refractive errors, they have notable limitations in the following situations: Anisometropia and local functional insufficiency: When the degree of refractive error is high or the difference in degree between the two eyes is large, it is difficult to take into account the imaging quality of different areas of the retina by simply relying on the overall refractive power correction, which can easily lead to problems such as eye fatigue and difficulty in binocular fusion.

[0003] Near vision problems in presbyopia: The essence of presbyopia is the decrease in the elasticity of the lens, which leads to a weakening of the accommodative ability. Existing solutions such as bifocals and progressive multifocal lenses can improve near vision to a certain extent, but the visual quality is unstable when switching between different viewing distances and directions, and image jumps and distortions are prone to occur in the peripheral areas.

[0004] In recent years, several vision correction or training devices combining electronic displays and optical components have emerged, such as variable diopter systems based on augmented reality (AR) technology and visual function training systems in virtual reality (VR) environments. These devices typically present specific patterns on a display screen, using optical components to guide light into the eye to intervene in visual function. Their advantage lies in the ability to flexibly adjust training content through software, enabling personalized rehabilitation plans. However, these systems generally suffer from complex structures, large size, and high costs, and rely on electronic components such as batteries and computing units, limiting their widespread adoption in daily wear and long-term use.

[0005] On the other hand, some studies have attempted to finely control the light field using microstructured optical elements, such as geometric phase lenses and microlens arrays, to achieve thinner, lighter, and more efficient vision correction. These technologies have potential in improving optical performance and reducing device size, but currently they are mainly geared towards conventional refractive correction applications, with less focus on multi-regional, adjustable visual function training scenarios.

[0006] Furthermore, in the field of visual rehabilitation training, there are also methods that use specific gratings, contrast patterns, etc., to stimulate retinal photoreceptor cells or the visual cortex. These methods usually need to be performed in specialized medical institutions, with fixed training parameters, making it difficult to make real-time, precise adjustments based on individual patient differences. At the same time, traditional training devices mostly use planar optical elements, which have limited ability to control the spatial distribution of the light field and cannot achieve the function of independent and continuous adjustment of different areas within the visual field.

[0007] In summary, existing technologies still have shortcomings in the following aspects: (1) Lack of localized accommodation: Traditional refractive correction methods are difficult to provide differentiated optical stimulation to different areas of the retina, and cannot specifically improve local vision problems.

[0008] (2) Poor portability of the device: Existing visual training systems that combine electronic displays are generally large in size and complex in structure, and are not suitable for use as everyday wearable devices.

[0009] (3) Insufficient precision of parameter adjustment: The parameter adjustment granularity of most training devices is relatively coarse, which makes it impossible to achieve continuous and precise control of parameters such as light field distribution, stimulation area, and contrast, and it is difficult to meet the needs of individualized and progressive rehabilitation.

[0010] (4) Lack of non-invasive devices to cure myopia: Currently, most non-surgical myopia products on the market focus on controlling the degree of myopia, and there is a lack of portable devices that can substantially reduce the degree of myopia and a better solution between traditional glasses and laser surgery.

[0011] (5) Lens refractive surgery cannot solve the problem of secondary vision loss. After lens refractive surgery, the eyes still need to pay attention to the duration of eye contact and avoid prolonged close viewing to prevent vision loss.

[0012] Therefore, it is necessary to propose a vision repair device with a relatively simple structure, no need for complex electronic control, and capable of multi-regional adjustable daily quantity through pure optical means. This device can serve as an auxiliary optical instrument for daily wear, and can also perform zoned and progressive visual function training for refractive errors such as myopia and presbyopia through differential control of the light field, ultimately achieving a one-time cure and preventing recurrence. Summary of the Invention

[0013] The purpose of this invention is to provide a multi-region adjustable vision restoration device and its usage method based on the principle of differential surface imaging. This device can quantitatively restore vision (restoring more than one degree of vision per day). Through adjustable diamond-shaped holes on the pupil clock lens and beaded mesh lens, combined with scale indicators and slider fine-tuning, it achieves precise restoration of vision in different regions. It also utilizes the "jelly vision" effect to slow down vision deterioration and improve visual adaptation. Furthermore, this invention reduces the limitation on screen time, so that vision is no longer associated with refractive errors caused by prolonged eye use or excessive close-up viewing. In this respect, this invention is equally effective for people with decreased vision and those with normal vision. Specifically, the amount of vision loss due to refractive errors is minimal. For example, using this device to restore vision allows a person to obtain a clear field of vision even when wearing different lenses within a range of several hundred degrees. The innovation of this device lies in abandoning traditional lens-based refractive vision restoration methods and instead using a different method of imaging the original path information of light in its natural state to restore vision.

[0014] To achieve the above objectives, this invention provides the following technical solution: a multi-region adjustable vision restoration device based on the principle of differential surface imaging and its usage method. This device is based on the principle of differential surface imaging. The lens body inside the pupil clock frame serves as the basic carrier connecting to the optical path of the eyeball. The diamond-shaped aperture on its end face is simply hollowed out, used to provide a jelly-like visual field and utilize its characteristic of attaching to the contour of an obstruction—when the obstruction (such as a lens) is within 20cm in front of the eyeball, the edge of the diamond-shaped aperture forms an elastic visual field boundary similar to jelly, allowing the "locally clear area" required for differential surface imaging to be achieved. The natural appearance of the lens; the clock scale provides a directional reference for subsequent dynamic adjustments, with markings corresponding to the distribution of differential surfaces in different directions of the eyeball, helping users perceive subtle changes in the occlusion position; the inner pupil clock bearing provides flexible rotation, allowing the lens to rotate 360 ​​degrees for fine-tuning, gradually achieving a comprehensive repair effect on the jelly vision generated by the differential surfaces; the adjustment slider between the frame and the lens body complements the bearing rotation, changing the morphological parameters of the rhomboid aperture through mechanical linkage, allowing the device to gradually occlude the corneal surface at different positions without blind spots, thereby exposing the jelly vision generated by the differential surfaces at different positions. The entire structure is designed around "precise control of the position, shape, and angle of the occlusion object," essentially transforming the "elastic attachment" of the jelly vision into an operable mechanical structure, creating stable physical conditions for direct imaging of the differential surfaces, and structurally laying the foundation for repairing vision using the advantages of differential surface imaging; The beaded mesh frame design complements and expands upon the pupil clock frame, making it suitable not only for safe indoor environments but also for complex outdoor settings. The inner beaded mesh lens body, as the core component for optical path control, allows for arbitrary arrangement of the intersecting lines on its end face. This aligns with the jelly vision's logic of "attached to the silhouette of an obscuring object"—the polygonal network of intersecting parallel lines acts as an "invisible obscuring skeleton," preserving sufficient light-transmitting areas for the differential surfaces to capture optical path data while simultaneously providing the obscuring object silhouette for the jelly vision through the lines' obstruction. Compared to the pupil clock, the more extensive beaded mesh at the contour boundaries allows more near-planar individual differential surfaces to be directly imaged using optical path information. The inner beaded mesh bearing supports 360-degree lens rotation, preventing the fixed line layout from only affecting differential surfaces at fixed contour boundaries. The adjustment slider between the frame and the lens body adjusts the width of the intersecting parallel lines and the size of the diamond-shaped holes, altering the density of the light-transmitting area to expose differential surfaces in blind spots for more comprehensive vision restoration. This design allows the beaded frame to cover more of the corneal area like a spider web, becoming a key bridge connecting the principles of differential surface imaging with practical application scenarios.

[0015] Furthermore, the design of the beaded adjustment slider closely aligns with the core advantage of differential surface imaging: "direct imaging via a single curved surface optical path is unaffected by refractive errors." Adjusting the size of the rhomboid aperture directly corresponds to the "attachment range" of the jelly field of vision: the smaller the aperture, the shorter the outline boundary, and the smaller the jelly field of vision; the larger the aperture, the longer the outline boundary, and the larger the jelly field of vision. The more parallel lines, the more rhomboid apertures, and the longer the total outline boundary, the more jelly fields of vision can be attached, and the faster the vision restoration speed. However, limited by the brain's biological mechanisms, the speed cannot be increased proportionally.

[0016] Furthermore, the natural phenomenon of jelly vision is transformed into a practical mechanism for the device. The core is to gradually increase the exposure of the jelly vision across the entire corneal surface by rotating the lenses and changing the inner angle of the rhomboid aperture, thereby restoring vision. The essence of jelly vision is the elastic optical imaging effect formed by the occluder within 20cm in front of the eyeball—the closer to the eyeball, the larger the field of view, covering more of the micro-curvature; the farther away, the smaller the field of view, covering only the core area. The pupil clock frame's wearing position adjustment utilizes this principle: users can precisely control the occlusion distance within an effective range of 20cm by adjusting the tightness of the temples, the height of the nose pads, or the overall forward / backward movement of the frame. For example, appropriately moving the frame backward or forward creates a linked design of "distance-field of view-micro-curvature coverage," allowing the device to bypass complex optical calculations and directly adapt to individual physiological differences through mechanical adjustment, transforming jelly vision from an "accidental phenomenon" into a "controllable vision restoration tool." The closer the jelly vision is to the cornea, the better the effect; for example, the eyelid edge can serve as the outline for the generation of jelly vision.

[0017] Furthermore, the polygonal structure and quantity design of the intersecting lines in the beaded net are an application of the "jelly-like vision" characteristic of "attaching to the silhouette of the obstruction"—the jelly-like vision adheres to the edge of the obstruction, such as wooden strips, like a "liquid film," while the polygonal intersecting lines outline a similar contour boundary like a "rigid skeleton," with the extension direction of the lines following the contour of the obstruction. The quantity setting of four to several lines (the maximum value depends on the area of ​​the differential surface and the degree of obstruction of the vision) is based on the following: too few lines (such as a few) will result in excessively large spacing between the lines, forming a hollow, continuous, elastic vision boundary, which is slow to repair and difficult to fully repair, but will not affect the usability; too many lines (such as hundreds) will make the lines too dense, the obstructed area too large, reduce the effective light-transmitting area, cause loss of vision, be detrimental to daily life, and create safety hazards. In use, the rotation of the beaded bearing drives the lens, thus "moving the attachment position of the jelly field of vision." The network it forms covers a new set of differential surfaces on the cornea. Because these differential surfaces are not obstructed by other lines, they can directly receive light path data and form a clear image. With each rotation, the network covers another set of differential surfaces, continuously providing the visual system with direct imaging data "without synthesis errors," in a cyclical manner. This "angle change - covering a new area - directly capturing data" mode perfectly matches the "movement updates the field of vision" characteristic of the jelly field of vision, allowing the advantages of differential surface imaging to continuously apply to the entire corneal area.

[0018] Furthermore, the clock scale serves to provide a "quantifiable directional language" for rotating the pupil clock frame. The periodic rotation of small angles cleverly combines the characteristics of integral imaging and differential surface imaging—while direct imaging via differential surfaces is unaffected by refractive errors, the field of view of a single differential surface is limited and cannot cover the entire visual scene. The clock scale divides the circumference of the frame into 12 reference positions (corresponding to the 12 o'clock positions on a clock face), each corresponding to a different cluster of differential surfaces in the eye: for example, "12 o'clock" corresponds to the upper differential surface, "3 o'clock" to the right, "6 o'clock" to the lower, and so on. As the user gradually rotates the lens by small angles until an adjacent mark (e.g., from 12 o'clock to 1 o'clock), the position of the pupil clock diamond-shaped aperture shifts, exposing the previously obscured upper right differential surface cluster, which begins direct imaging; rotating further towards 2 o'clock exposes another set of differential surfaces. This process of "dynamically changing position - sequentially activating different differential surfaces - synthesizing a complete scene image" essentially replaces the traditional "single differential surface + integral synthesis" mode with "direct imaging data from multiple single differential surfaces." Since each differential surface is directly imaged, even with curvature differences caused by refractive errors, vision loss won't occur due to synthesis errors like with integral imaging. Instead, by stitching together multiple sets of clear data, it retains the advantages of differential surface imaging while solving the problem of insufficient single field of view. The clock scale provides a clear reference for rotation, avoiding blind rotation that could lead to gaps in vision restoration and ensuring the synthesized image is both complete and clear. The more markings on the frame and the more precise the lens rotation scale, the more accurate the vision restoration and the better the effect. Note that even rotating only according to the clock scale, the vision restoration effect is quantitatively controllable; only the fineness of the corneal repair area varies.

[0019] Furthermore, the operational logic of the bead mesh adjustment slider directly addresses the core advantage of differential surface imaging—"direct imaging of a single differential surface optical path without synthesis error." The key to differential surface imaging is allowing each differential surface to independently receive optical path data and form a clear image, eliminating the need to synthesize data from multiple surfaces as in integral imaging (the synthesis process is prone to curvature errors due to refractive errors, leading to decreased vision). When the width of the bead mesh forming the rhombus aperture is reduced, the essence is to reduce the obstructed area, allowing more differential surfaces to be exposed to light outside the obstruction. Each exposed differential surface can directly receive the unobstructed optical path data and independently complete imaging—this is like "opening independent windows" for multiple differential surfaces, with each window displaying a clear image, eliminating the need for post-processing stitching. Therefore, adjusting the slider to "reduce the obstruction width - expand the rhombus aperture" is an operation that increases the jelly-like field of view exposed by differential surfaces at different positions to improve vision.

[0020] This invention provides a multi-region adjustable vision restoration device based on the principle of differential surface imaging and its usage method, which has the following beneficial effects: 1. This device is based on the principle of differential surface imaging and utilizes a jelly-like visual field formation mechanism to achieve precise control of the occluder in front of the eye. Placing the occluder within 20cm activates an elastic visual field, and the size and interior angle of the rhomboid aperture can be dynamically adjusted using a slider to adapt to the needs of different regions of the differential surface. Because the curvature of the differential surface is approximately planar, it can directly form an image without being affected by refractive errors. This design allows the optical path data of a single differential surface to be directly converted into a clear image, avoiding the accumulation of aberrations caused by curvature differences during integral synthesis. This fundamentally improves imaging stability and provides users with a vision restoration experience that better conforms to physiological mechanisms.

[0021] 2. The spiderweb lens employs a multi-sided, intersecting linear shielding structure (four to several lines, depending on the size of the differential surface and the degree of visual field loss) that alters the light path, perfectly matching the adhesion characteristics of jelly vision. Its line layout dynamically covers the corneal differential surface area with rotation, precisely capturing the light path data of individual differential surfaces through angular changes. Because the differential surface is an approximate plane after multiple differentiations, the directly imaged image has high consistency with the real object, effectively avoiding the refractive errors caused by the need for multi-data synthesis in integral imaging. This structure is particularly suitable for outdoor scenarios, making visual perception closer to a natural, clear state and significantly improving visual quality in complex environments. The spiderweb lens is specifically designed for outdoor non-driving vehicle scenarios; its cone-shaped expansion of the field of vision ensures reduced obstruction of the visual field, with no visual field loss during walking.

[0022] 3. The device incorporates a clock-scale and adjustment slider linkage mechanism. The pupil clock lens and the beaded mesh lens periodically rotate by a small angle, such as once a day, changing the position of the rhomboid aperture. This dynamic adjustment strategy prompts the periodic switching of multi-differential surface optical path data, preventing a single area from being affected by refractive errors for an extended period. For example, rotation allows the occluded area to cover different differential surfaces of the cornea. While a single image relies on the current smallest differential surface, periodic switching allows different areas to alternately participate in image formation and vision restoration, reducing image quality degradation caused by curvature deviations. This design upgrades static occlusion to dynamic adaptation, continuously advancing the restoration imaging and improving clarity.

[0023] 4. The device features two frame types: the "Pupil Clock" and the "Beaded Mesh." The "Pupil Clock" is suitable for low-stimulation indoor scenarios, while the "Beaded Mesh," with its multi-diamond-shaped perforation structure, is adapted for outdoor walking needs. By selecting different frames or using combinations, the amount of light entering and the accuracy of occlusion can be specifically controlled: in safe indoor scenarios, the "Pupil Clock" reduces the stimulation of the eyes by irrelevant light sources; outdoors, where unobstructed vision is required, the "Beaded Mesh" ensures the integrity of the field of vision and avoids danger. The "Spider Mesh" form is an enhancement of the "Pupil Clock" form, offering superior vision restoration. Furthermore, due to the clustered diamond-shaped perforations, no additional adjustment of the diamond-shaped perforation boundaries is needed to achieve the desired visual field, making it more convenient to use than the "Pupil Clock." Its application scenarios include indoor scenarios where attention to the surrounding environment is not required, and outdoor scenarios where attention to the surrounding environment is necessary. This design breaks through the limitations of a single occlusion mode, enabling the device to cover all scenarios from static fine observation to dynamic environmental adaptation. It allows users to obtain adaptive differential surface imaging support under different lighting and activity conditions, significantly improving practicality and scenario compatibility.

When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] How to use: 1. Place the pupil clock frame 1 in a suitable position in front of your eyes. Utilize the pupil clock lens body 2 on its inner side and the pupil clock diamond-shaped hole 3 on its end face. Adjust the wearing position to control the distance between the occluder and the eyeball, adapting to the actual visual field position needs of different individuals. During operation, rely on the jelly vision formation mechanism to ensure that the occluder is placed within 20cm in front of the eyeball to generate a flexible visual field.

[0030] 2. Adjusting the core parameters of the pupil clock frame 1. The size and inner angle of the pupil clock rhomboid aperture 3 are adjusted via the pupil clock adjustment slider 6 located between the pupil clock frame 1 and the pupil clock lens body 2. Based on the area variation law of the jelly field of vision, the inner angle of the pupil clock rhomboid aperture 3 is reduced as the obstruction gets closer to the eyeball, maintaining the original coverage range of the differential surface and adapting to the variable imaging conditions within 20cm in front of the eyeball.

[0031] 3. Optimize the optical path using the clock mark 4 on the end face of the pupil clock frame 1. Based on the rotation direction indicated by the clock mark 4, periodically rotate the pupil clock frame by a small angle to dynamically change the position of the pupil clock rhomboid hole 3, synthesize multi-differential surface optical path data, and avoid the influence of refractive errors.

[0032] 4. Wear the beaded mesh frame 7 and adjust the basic structure. Wear the beaded mesh frame 7 in front of your eyes. Through the beaded mesh lens body 8 on its inner side and the hollowed-out diamond-shaped holes 9 formed by the intersecting lines of the beaded mesh on its end face, use the beaded mesh adjustment slider 12 provided between the beaded mesh frame 7 and the beaded mesh lens body 8 to adjust the size and inner angle of the diamond-shaped holes of the beaded mesh.

[0033] 5. Optimize the imaging accuracy of the beaded mesh frame 7. By adjusting the beaded mesh slider 12, the width of the intersecting opaque lines 9 of the beaded mesh is reduced, and the size of the diamond-shaped aperture is enlarged to ensure that the optical path data of a single differential surface is directly imaged, reducing the risk of vision loss caused by integral synthesis errors.

[0034] 6. Utilize the characteristics of the beaded diamond-shaped holes 9. The beaded diamond-shaped holes 9 of the main body 8 of the beaded lens are designed as a group distribution structure, with the number ranging from one to several (the maximum value depends on the actual imaging effect and the size of the differential surface), adapting to the adhesion characteristics of the jelly field of vision; during use, the angle changes to gradually and fully cover the corneal differential surface area, realizing direct capture of imaging data. Example:

[0035] Example 1: Basic adjustment application of the pupil clock frame 1 in an indoor static scene When reading at close range at a desk indoors, the user wears the pupil clock frame 1, a multi-area adjustable vision restoration device based on the principle of differential surface imaging. The pupil clock lens body 2, located on its inner side, is aligned with the line of sight. By fine-tuning the wearing position, the user maintains a distance of less than 20cm between the obstruction (i.e., the front end of the pupil clock frame 1) and the eyeball. This distance, based on the jelly vision formation mechanism described in Figure 1, generates an flexible field of vision to adapt to the needs of the differential surface imaging area. Referring to the rotation direction marked by the clock scale 4 on the end face of the pupil clock frame 1, the user slightly rotates the pupil clock lens 1 at small angles at regular intervals, changing the projection position of the pupil clock rhomboid aperture 3 on the cornea. This operation, based on the differential surface imaging principle described in Figure 2, uses the differential surface optical path data attached to the contour to form an image, avoiding imaging deviations caused by refractive errors. During the process, the shielding properties of the rhomboid aperture 3 of the pupil clock can reduce the stimulation of the eyeball by irrelevant indoor light sources. Combined with the clarity of direct imaging by the differential curved surface, users can stably see the text in books and electronic screens without experiencing a decline in vision due to refractive problems.

[0036] Example 2: Rotation optimization application of the pupil clock frame 1 or spider web frame 7 in an indoor dynamic scene. While slowly pacing and tidying up indoors, the user continues to wear the aforementioned device's pupil clock frame 1 or spider web frame 7, maintaining a distance of no more than 20cm from the eyeball to preserve the elasticity of the jelly vision. The angle can be rotated by one degree every other day to gradually advance the vision-restoring effect of producing jelly vision on different areas of the cornea's micro-curvature.

[0037] Example 3: Basic Adjustment Application of Beaded Frame 7 in Outdoor Walking Scenarios When walking on an outdoor sidewalk, the user switches to wearing the beaded mesh frame 7 of the aforementioned device, aligning the beaded mesh lens body 8 on its inner side with their line of sight. By adjusting the wearing position, the beaded mesh frame 7 is kept within 20cm of the eyeball (still relying on the jelly vision mechanism to generate an elastic field of vision). During this process, the polygonal structure of the beaded mesh rhomboid aperture group 9, combined with the adhesion characteristics of the jelly vision, directly captures imaging data by covering different micro-curvature areas of the cornea. Even with changes in outdoor light intensity, the stable amount of light intake and clear micro-curvature imaging allow the user to clearly identify road conditions and pedestrians without experiencing visual distortion caused by refractive errors.

[0038] Example 4: Fine-tuning application of beaded frame 7 in complex outdoor lighting scenarios When walking in areas where sunlight and shade alternate outdoors, the user wears beaded mesh frames 7 and ensures they are within 20cm of the eyeball to maintain jelly vision. The polygonal structure (four to several lines) of the beaded mesh diamond-shaped perforations 9 continuously works with the adhesion characteristics of the jelly vision, allowing image data to be directly captured under different lighting conditions. In this scenario, the device ensures stable light intake during outdoor walking and avoids the effects of refractive errors through direct imaging via differential curved surfaces. Users can clearly judge road conditions under complex lighting conditions without the limited field of vision problem of traditional sunshades.

[0039] Example 5: Application of dual-frame combination in indoor / outdoor switching scenarios Users need to read indoors and then go to an outdoor convenience store to shop. First, wear the Pupil Clock Frame 1, adjusting the distance between it and the eyeball to within 20cm. Increase the inner angle of the Pupil Clock's diamond-shaped hole 3 using the Pupil Clock adjustment slider 6 (adapting to the jelly field of vision for close-up reading) to ensure clear vision of the text. When switching to the Beaded Mesh Frame 7 before going outside, adjust the distance to within 20cm to maintain the jelly field of vision. During this process, the Pupil Clock Frame 1's light-blocking properties meet the need for reduced stimulation indoors, while the polygonal lines and layout of the Beaded Mesh Frame 7 adapt to the needs of outdoor walking. Both use differential curved surfaces for direct imaging to avoid refractive errors, and the switching requires no complicated operations. The user's visual transition from indoors to outdoors is smooth, maintaining clear vision throughout without any risk of vision loss.

[0040] Example 6: Application of changes in the relative position of binoculars and eyes When wearing the pupil clock frame 1 and the spider web frame 7, the user can keep their line of sight fixed when looking at an object that is stationary relative to themselves. After a period of use, they can slightly turn their head, and the frame will follow the head's movement while the eyeballs remain relatively still relative to the body. When looking at an object that is moving relative to themselves or at an object in a different position, keeping the head still while turning the eyeballs, the relative position of the frame and the eyes can be changed, thus enabling more corneal area differential surface imaging.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

When the obstruction is closer to the eyeball, the inner angle of the pupil clock rhomboid hole (3) is reduced to maintain the coverage of the differential curved surface field of vision unchanged, adapting to the state where the relative distance between the eyes and objects remains unchanged in indoor reading, learning, entertainment and other scenarios.

7. The multi-region adjustable vision restoration device based on the differential surface imaging principle and its method of use according to claim 1, characterized in that: The adjustment of the beaded mesh adjustment slider (12) requires increasing or decreasing the width of the beaded mesh intersecting parallel lines to change the size of the rhombus hole (9), ensuring that the optical path data of each differential surface in different areas can be directly imaged without dead angles, reducing the risk of vision loss caused by integral synthesis error, and addressing the problem of jelly field failure when using the same differential surface in the same position for a long time to generate jelly field of vision.

8. The multi-region adjustable vision restoration device based on the differential surface imaging principle and its method of use according to claim 1, characterized in that: The pupil clock lens (2) and the beaded mesh lens (8) are independently rotated through the pupil clock bearing (5) and the beaded mesh bearing (11), respectively. The two lenses are rotated so that the pupil clock rhomboid hole (3) and the beaded mesh rhomboid hole (9) cover different areas, thereby making the jelly field of vision appear stably at different differential surface positions where vision needs to be repaired. This is combined with the brain's capture of independent imaging data to complete vision repair and to address the problem of jelly field of vision failure when the same differential surface is used for a long time.

9. The multi-region adjustable vision restoration device based on the differential surface imaging principle and its method of use according to claim 1, characterized in that: The pupil clock lens (2) and the spider web lens body (8) that change the light path refer to shielding objects that can absorb, reflect, and refract light waves. In simpler terms, for any light-blocking object, mirror object, or object that refracts light, the path of light changes when it passes through these objects, but does not change when it does not pass through them. This means that two paths of light appear on either side of the edge of these objects. Based on this characteristic, light outside the shielding object does not change its path before entering the eye, but it will produce a jelly field of vision outside the outline of the shielding object. By changing the light path, a break in the light path appears at the outline of the shielding object, and a break in the field of vision also appears at this point. The boundary of the break is the outline of the shielding object, and the image at this point is formed by a differential surface, called a jelly field of vision. This principle is the foundation of the device's vision restoration effect.

10. The multi-region adjustable vision restoration device based on the differential surface imaging principle and its method of use according to claim 1, characterized in that: A differential surface is the smallest surface that can be imaged independently, obtained by finitely differentiating the corneal surface. The collection of differential surfaces constitutes the corneal surface. The image formed by the differential surface at the visual field tomography site differs from the image formed in other areas of the cornea without visual field tomography. The former is clear and the image is reduced in size, while the latter shows an image that is the same size as the real object but has lower clarity.
