Description

Technical Field

[0001] This disclosure pertains to the field of optical devices, and more specifically relates to a pair of eyeglasses. Background Technology

[0002] Myopia is a societal problem. Research indicates that myopia defocus can effectively inhibit axial elongation and may even shorten the axial length. Myopia defocus (also known as positive defocus) stimulation refers to the phenomenon where, when the human eye focuses on an image plane that is clearly focused on the retina (the principal image plane), if another image plane or part of the principal image plane can be simultaneously focused in front of the retina through optical means, positive defocus stimulation is formed in optometry. Defocus stimulation in the peripheral visual field is equally effective. Current research suggests that switching to peripheral defocus stimulation can enhance the effect of myopia defocus stimulation, showing superior performance in myopia control.

[0003] Regarding the application environment of peripheral defocus stimulation, it is often set up to be attached to a screen that can display images, such as a monitor, which has certain limitations in its use. In addition, different users require different targeted stimulation to achieve a good effect of inhibiting axial elongation, that is, ensuring that myopia does not worsen or even slows down the progression of myopia. Summary of the Invention

[0004] This disclosure is made based on the aforementioned needs of the prior art. The technical problem to be solved by this disclosure is to provide an eyeglass that can be adjusted to change the position of the defocus stimulus applied to the periphery of the central visual field in order to inhibit axial elongation.

[0005] To address the aforementioned problems, the technical solutions provided in this disclosure include:

[0006] A pair of glasses is provided, comprising: a frame including a track extending in a predetermined direction; a first stimulation module slidably connected to the track for sliding along the track; the first stimulation module having a first defocus stimulation area; and a second stimulation module slidably connected to the track for sliding along the track; the second stimulation module having a second defocus stimulation area; when the first stimulation module and the second stimulation module are installed in the same side frame, a blank area is formed between the first defocus stimulation area and the second defocus stimulation area; the first stimulation area and the second stimulation area correspond to the peripheral field of vision of the human eye, and the blank area corresponds to the central field of vision of the human eye; by sliding the first stimulation module and the second stimulation module on the track, the positions of the first defocus stimulation area and the second defocus stimulation area in the field of vision of the human eye are changed, thereby changing the position and range of the blank area.

[0007] By setting a first defocus stimulation region and a second defocus stimulation region, the images formed through these two regions fall in front of the retina. A blank region is set so that the images formed through this blank region fall on the retina. The combined effect of the images falling in front of and on the retina creates a tendency for the retina to move forward, thereby inhibiting axial elongation. The first and second defocus stimulation regions are positioned around the blank region so that the image formed in the central field falls on the center of the retina, and the image formed in the peripheral area of ​​the central field falls on the anterior periphery of the retinal center, forming peripheral defocus stimulation. As the first and second stimulation modules move, the first and second defocus stimulation regions dynamically stimulate different positions in the peripheral area, better inhibiting axial elongation and even shortening the axial length. Furthermore, the positions of the first and second stimulation modules can be adjusted according to the user's individual needs so that the blank region corresponds to the central region of the eyeball.

[0008] Preferably, the track extends in the left-right direction.

[0009] This configuration, adapted to the plane of the user's eye, allows stimulation to be applied at different locations around the user's central visual field as the first and second stimulation modules move, ensuring that the corresponding image is projected in front of the retina, thus achieving dynamic peripheral defocus stimulation. Furthermore, by moving a blank area to correspond to a reference position within the user's central visual field, and then moving the modules away from each other at that reference position, peripheral defocus stimulation is created in the eye to inhibit axial elongation.

[0010] Preferably, the first defocus stimulation region and the second defocus stimulation region include dot-shaped defocus patterns and / or ring-shaped defocus patterns.

[0011] This configuration ensures that the image of an object passing through the first defocus stimulation area and the second defocus stimulation area will fall in front of the retina, thereby pulling the retina forward to inhibit axial elongation.

[0012] Preferably, the first stimulation module and the second stimulation module are arranged one after the other.

[0013] This design allows the first and second stimulation modules to slide over a wider range, adapting to different users' eye conditions.

[0014] Preferably, the first stimulation module and the second stimulation module are respectively arranged on the left and right sides of the same side frame; a gap is formed between the first stimulation module and the second stimulation module; when the first stimulation module and the second stimulation module slide towards each other in the left and right direction, the gap decreases; when the first stimulation module and the second stimulation module slide away from each other in the left and right direction, the gap increases.

[0015] This design allows external objects to be imaged directly onto the corresponding area of ​​the eye through the intervals, reducing light loss and resulting in a clearer image, thus ensuring a better viewing experience for the user. Furthermore, the range of these intervals can be adjusted by sliding the first and second stimulation modules to suit different users.

[0016] Preferably, the peripheral contour of the interval includes an arc shape to conform to the field of view of the human eye.

[0017] The above settings are designed so that the pattern presented by the intervals basically corresponds to the field of view of the human eye, so that peripheral defocus stimulation can be performed more accurately.

[0018] Preferably, the glasses further include: a first rack, arranged along the predetermined direction and connected to the first stimulation module; a second rack, arranged along the predetermined direction and connected to the second stimulation module, the first rack and the second rack being arranged opposite to each other; and a gear, the first rack and the second rack being respectively arranged on both sides of the rotation center of the gear; the gear being simultaneously meshed with the first rack and the second rack; the first rack and the second rack being slidably arranged on the track.

[0019] This configuration allows the glasses to have a more compact structure, with gears driving the movement of the first and second racks to achieve synchronization between the first and second stimulation modules.

[0020] Preferably, the first rack is adjustablely fixedly connected to the first stimulation module to adjust the relative position of the first rack and the first stimulation module; the second rack is adjustablely fixedly connected to the second stimulation module to adjust the relative position of the second rack and the second stimulation module.

[0021] The above structure is designed to specifically meet the eye conditions of different users by defining the position of the blank area, thereby achieving a good peripheral defocus stimulation effect and effectively inhibiting axial elongation.

[0022] Preferably, the glasses further include: a motor electrically connected to the gear; and a controller electrically connected to the motor to control the direction and amount of rotation of the gear.

[0023] The circuit connection structure described above allows the controller to control the movement of the motor, thereby limiting the rotation of the gears and changing the positions of the first and second stimulation modules. This enables the images formed by the eye in the areas corresponding to the first and second defocus stimulation regions to fall in front of the retina, working together with the image in the center of the field of vision that falls on the retina to suppress the tendency of axial elongation.

[0024] Preferably, the glasses include a left frame and a right frame, and the left frame and the right frame have the same structure.

[0025] This setup allows for simultaneous peripheral defocus stimulation of both the user's left and right eyes, facilitating precise eye control to some extent.

[0026] Compared to existing technologies, this disclosure utilizes a first stimulation module and a second stimulation module that are slidably arranged in a left-right direction to alter the position of peripheral defocus stimulation received in the area surrounding the user's central visual field. While ensuring that the image of an object in the corresponding area of ​​the central visual field falls on the retina, the image formed in the visual field area corresponding to the position of the defocus stimulation falls in front of the retina, thereby creating a tendency to pull the retina forward and inhibiting axial elongation. Furthermore, the positions of the first and second defocus stimulation areas can be adjusted specifically according to the different eye conditions of each user. Simultaneously, corresponding mechanical structures and circuit mechanisms are incorporated to achieve relatively intelligent dynamic changes within a limited spatial structure, generating corresponding dynamic peripheral defocus stimulation.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] In the description of the embodiments of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the term "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0045] Throughout the text, the terms “top,” “bottom,” “above,” “below,” and “on top” refer to the relative positions of components of the device, such as the relative positions of the top and bottom substrates within the device. It is understood that the device is multifunctional and independent of its spatial orientation.

[0046] The widespread use of display devices has increased the burden on the human eye. Under conditions of prolonged close-range observation, the ciliary body needs to change the shape of the lens in order for the image entering the eye to fall on the retina, thus affecting the focal length of the lens. If the eye is in a state of accommodation for a long time, and the ciliary body remains in an overly tense state, it is prone to developing into true myopia. This phenomenon is becoming increasingly common, especially among adolescents and children.

[0047] Axial myopia defocusing has been shown to have a certain effect on inhibiting myopia. Its working principle is as follows: Figure 7 As shown, when the human eye focuses on an image plane, that image plane can be clearly imaged onto the retina 19, and its light propagation path is referenced. Figure 7 19a, referred to as the principal image plane, is the image plane that, when the principal image plane falls on the retina 19, is positioned so that another image plane appears in front of the retina 19 by means of optical means. Its light propagation path is referenced to... Figure 7 In the image plane 19b, the defocus plane is formed by the combined action of the two image planes. This causes the eye to want to see the image presented in front of the retina 19 clearly, which moves the retina 19 forward to inhibit the elongation of the eye axis and may even reduce the degree of myopia.

[0048] In addition, peripheral defocus also plays a role in inhibiting axial elongation. Its working principle is as follows: Figure 8 As shown, by means of optical means, the image of the area located on the periphery of the area corresponding to the central field of vision is placed in front of the retina 19, so as to stimulate the eye to adjust and project the image of the periphery onto the retina 19, thereby causing the retina 19 to tend to move forward, inhibiting the elongation of the eye axis, and even causing the eye axis to shorten, thereby achieving the effect of reducing the degree of myopia.

[0049] To facilitate understanding of the embodiments of this application, the following will provide further explanation and description with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this application.

[0050] This embodiment provides a pair of glasses, such as Figure 1-6 As shown. By configuring the glasses, it is possible to prevent the wearer's myopia from increasing, or even to reduce the degree of myopia.

[0051] The glasses include a frame, a first stimulation module 1, and a second stimulation module 2.

[0052] In this embodiment, the presence or absence of lenses on the frame is not limited. However, when the glasses include lenses, the lenses are mounted on the glasses by the frame. The first stimulation module 1 and the second stimulation module 2 are positioned behind the lenses, meaning that when the user wears the glasses, the first stimulation module 1 and the second stimulation module 2 are closer to the user's face relative to the lenses, so as not to affect the image of objects in the environment presented through the lenses. If the first stimulation module 1 and the second stimulation module 2 are positioned in front of the lenses, objects in the environment will first pass through the first stimulation module 1, the second stimulation module 2, and the area between the first stimulation module 1 and the second stimulation module 2. When the refractive indices are different, the image will be distorted, affecting the imaging effect through the stimulation modules. When these objects enter the eye through the myopia lens, they will simultaneously affect the imaging effect of the myopia lens and the stimulation effect of the peripheral defocus stimulation.

[0053] Furthermore, the frame includes a track extending in a predetermined direction to provide movement guidance for the first stimulation module and the second stimulation module. The track is disposed on the frame and extends in a left-right direction. The track is disposed on at least one side of the frame; specifically, the track can be disposed on the upper frame, lower frame, or both, depending on the specific shape of the frame. When the frame has both an upper and lower frame, and the track is disposed on both frames, a more stable sliding structure is achieved.

[0054] The track extends in a left-right direction, configured to fit the plane of the user's eyes. Thus, when the first and second stimulation modules move, stimulation can be applied at different locations around the user's central visual field, causing the corresponding image to appear in front of the retina, thereby achieving dynamic peripheral defocus stimulation. Furthermore, by moving the blank area to correspond to the user's central visual field to determine a reference position, and then moving away from each other at this reference position to stimulate the peripheral area, forming peripheral defocus stimulation in the eye to inhibit axial elongation.

[0055] The first stimulation module 1 is slidably connected to the track to slide along the track; the first stimulation module 1 is provided with a first defocus stimulation region 3; the second stimulation module 2 is slidably connected to the track to slide along the track; the second stimulation module 2 is provided with a second defocus stimulation region 4. Further, the first defocus stimulation region 3 and the second defocus stimulation region 4 are regions with a certain refractive power, which is 2D-5D greater than the blank region, and include dot-shaped defocus patterns and / or annular defocus patterns. The dot-shaped defocus patterns in the first defocus stimulation region 3 and the second defocus stimulation region 4 are as follows... Figure 13 As shown; a ring-shaped defocus pattern is set in the first defocus stimulation area 3 and the second defocus stimulation area 4, as shown. Figure 12 As shown. This arrangement ensures that the image of an object passing through the first defocus stimulation area and the second defocus stimulation area falls in front of the retina in the eye, thereby pulling the retina forward to inhibit axial elongation. Defocus patterns are known to those skilled in the art and will not be described further. Furthermore, the first stimulation module also includes a flat light area 7 to allow light to pass through.

[0056] like Figure 1 and Figure 5 As shown, the first stimulation module 1 and the second stimulation module 2 are mounted sideways within the same side frame, forming a group. A blank area 5 is formed between the first defocus stimulation area 3 and the second defocus stimulation area 4 within the group. The blank area 5 corresponds to the central field of view of the user's eye, and the first and second stimulation areas correspond to the peripheral field of view of the user's eye. The peripheral field of view is a ring-shaped area surrounding the central field of view. When the first stimulation module 1 and the second stimulation module 2 slide along the track, the positions of the first defocus stimulation area 3 and the second defocus stimulation area in the user's field of view change accordingly, thereby altering the position and extent of the blank area 5.

[0057] By setting a first defocus stimulation region and a second defocus stimulation region, the image formed through the two defocus stimulation regions falls in front of the peripheral area of ​​the retina. A blank area is set so that the image formed through the blank area falls on the center of the retina. The image falling in front of the retina and the image falling on the retina work together to create a tendency for the retina to move forward, thereby inhibiting axial elongation. The first and second defocus stimulation regions are positioned around the blank area so that the image formed in the central field falls on the center of the retina, and the image formed in the peripheral area of ​​the central field falls in front of the periphery of the center of the retina, forming peripheral defocus stimulation. As the first and second stimulation modules move, the first and second defocus stimulation regions can dynamically stimulate different positions in the peripheral area, thus better inhibiting axial elongation and even achieving the effect of shortening the axial length. Furthermore, the positions of the first and second stimulation modules can be adjusted according to the user's individual situation so that the blank area corresponds to the central area of ​​the eyeball.

[0058] Furthermore, such as Figure 2 As shown, a gap 6 is formed between the first stimulation module 1 and the second stimulation module 2. When the first stimulation module 1 and the second stimulation module 2 slide towards each other in the left-right direction, the gap 6 decreases, and correspondingly, the blank area 5 decreases. When the first stimulation module 1 and the second stimulation module 2 slide away from each other in the left-right direction, the gap 6 increases, and correspondingly, the blank area 5 increases. The peripheral contour of the gap 6 includes an arc shape to adapt to the visual field of the human eye. For example, if the first stimulation module 1 is located on the left side of one side of the frame, then the second stimulation module 2 is located on the right side of the same side of the frame. In this case, the peripheral contour of the right side of the first stimulation module 1 is arc-shaped; the peripheral contour of the left side of the second stimulation module 2 is arc-shaped, and the positions of the two arc shapes correspond to each other. That is, when the first stimulation module 1 and the second stimulation module 2 are connected, the gap 6 forms a circle to correspond to the central visual field of the human eye. When the first stimulation module 1 and the second stimulation module 2 are away from each other, the shape formed by the gap 6 is basically similar to the central visual field of the human eye.

[0059] Furthermore, the first defocus stimulation region 3 is located in the first edge region of the first stimulation module 1; the second defocus stimulation region 4 is located in the second edge region of the second stimulation module 2; the first edge region and the second edge region are the regions of the edges of the first stimulation module 1 and the second stimulation module 2 that are close to each other. To more easily describe the relative positional relationship of each structure and region, the description of the peripheral defocus stimulation device will be given in the context of it being placed on eyeglasses. For a single lens, the first stimulation module is located in the left side region of the lens, the second stimulation module is located in the right side region of the lens, the first edge region is the region on the first stimulation module near the right edge, and the second region is the region on the second stimulation module near the left edge. When the first stimulation module and the second stimulation module intersect or abut against each other, the interval 6 is essentially circular. In this case, the blank region 5 coincides with the interval 6. Through the above arrangement, when the first stimulation module and the second stimulation module move, including changes in position and changes in the size of the blank region 5, the light transmittance within the blank region 5 remains unchanged, enabling uniform imaging in the center of the eyeball without affecting the visual perception.

[0060] To enable the sliding of the first stimulation module 1 and the second stimulation module 2, the following structure is provided: Figure 3 As shown, the glasses also include a first rack 8, a second rack 9, and a gear 16. The first rack 8 is arranged along the predetermined direction and connected to the first stimulation module 1; the second rack 9 is also arranged along the predetermined direction and connected to the second stimulation module 2. The first rack 8 and the second rack 9 are slidably arranged on the track. The first rack 8 and the second rack 9 are arranged opposite each other, and the gear 16 is disposed between the first rack 8 and the second rack 9, with the first rack 8 and the second rack 9 located on the front and rear sides of the rotation center of the gear 16, respectively. The front side of the gear 16 meshes with one of the first rack 8 and the second rack 9, and the rear side of the gear 16 meshes with the other of the first rack 8 and the second rack 9. This arrangement allows the glasses to have a more compact structure, and the synchronization of the first stimulation module and the second stimulation module is achieved by the cooperation of the gear, the first rack, and the second rack.

[0061] For example, the track has a recessed interior. The first rack 8 is fitted against the front side of the track and can move relative to it. The second rack 9 is fitted against the rear side of the track and can also move relative to it. The gear 16 is placed inside the track between the first rack 8 and the second rack 9 and meshes with both racks. When the gear 16 rotates, when the first rack 8 moves to the left, the second rack 9 moves to the right; similarly, when the second rack 9 moves to the right, it moves to the left. This allows the first stimulation module 1 and the second stimulation module 2 to move towards each other and away from each other, adjusting the range of the blank area 5 to fit the user's glasses.

[0062] Furthermore, such as Figure 4 and Figure 5 As shown, the first rack 8 and the first stimulation module 1 are adjustablely fixedly connected to adjust their relative positions; the second rack 9 and the second stimulation module 2 are adjustablely fixedly connected to adjust their relative positions. This configuration allows for targeted adjustment based on the interpupillary distance of different users, making it suitable for various users simultaneously.

[0063] For example, such as Figure 5 and Figure 9As shown, the frame is provided with a first track 10 and a second track 11. The first track 10 is located on the upper side of the frame, and the second track 11 is located on the lower side of the frame. A groove is provided in the first track 10 so that the first rack 8 and the second rack 9 are slidably disposed in the groove. A gear 16 is provided between the first rack 8 and the second rack 9 and meshes with the first rack 8 and the second rack 9 respectively. A first sub-groove 12 is provided on the lower side of the first rack 8, a second sub-groove 13 is provided on the lower side of the second rack 9, and a third sub-groove 14 and a fourth sub-groove 15 are provided on the upper side of the second track 11. The first sub-groove 12 and the third sub-groove 14 are arranged opposite each other, and the second sub-groove 13 and the fourth sub-groove 15 are arranged opposite each other. The upper end of the first stimulation module 1 is disposed inside the first sub-groove 12, and its lower end is disposed inside the third sub-groove 14; the lower end of the second stimulation module 2 is disposed inside the second sub-groove 13, and its lower end is disposed inside the fourth sub-groove 15. When using these glasses, the relative positions of the first stimulation module 1 and the first rack 8 are first adjusted and fixed according to the user's own situation, as are the relative positions of the second stimulation module 2 and the second rack 9. The positions of the first stimulation module 1 and the second stimulation module 2 are adjusted by rotating the gear 16, thereby changing the positions of the first defocus stimulation area 3 and the second defocus stimulation area 4 in the human eye's field of vision, and thus changing the range of the blank area 5. The user can see objects clearly through the blank area 5, allowing the corresponding image to be projected onto the central area of ​​the retina. The image formed by the first defocus stimulation area 3 and the second defocus stimulation area 4 will fall in front of the peripheral area of ​​the user's retina, working together with the image on the retina to form peripheral defocus, thus creating a tendency to pull the retina forward, thereby inhibiting the elongation of the eye axis and even achieving the effect of shortening the eye axis.

[0064] For example, the frame is provided with a third track and a fourth track, the third track being located on the upper side of the frame and the fourth track being located on the lower side of the frame. The first rack 8 and the second rack 9 are vertically arranged within the third track, and a baffle is provided below the second rack 9 to prevent it from falling off. The gear 16 is disposed between the first rack 8 and the second rack 9, and as in the example above, the first rack and the second rack are able to move left and right along the frame under the drive of the gear. This simplified structure is referenced. Figure 10 As shown.

[0065] The glasses also include a motor 18 and a controller 17. For example... Figure 6As shown, the motor 18 is electrically connected to the gear 16 so as to drive the rotation of the gear 16 through the motor 18. The controller 17 is electrically connected to the motor 18 so as to control the direction and rotation amount of the gear 16 by controlling the motor 18, thereby controlling the relative movement direction and relative movement distance of the first rack 8 and the second rack 9, thereby changing the range of the blank area 5 corresponding to the central field of view of the user's eyes.

[0066] The eyeglasses include a left frame and a right frame, and the left and right frames have the same shape and structure, such as... Figure 11 As shown. This setup allows for simultaneous peripheral defocus stimulation of both the user's left and right eyes.

[0067] The glasses mentioned include, but are not limited to, eyeglasses used by users for daily purposes, such as myopia glasses, non-prescription glasses, glasses without lenses but only frames, AR glasses, VR glasses, and smart glasses.

It should be understood that the above description is only a specific embodiment of this application and is not intended to limit the scope of protection of this application.
