Description

Technical Field

[0001] The present application relates to the technical field of myopia prevention and control, and in particular to a lens with a dynamic defocused microlens structure and an eccentric design. Background Art

[0002] Current optical lenses based on peripheral defocus generally reserve a relatively large transparent optical zone (8-9mm) in the central area. The purpose is to ensure that the wearer can obtain clear vision when looking straight ahead in the primary eye position. However, studies have shown that the effect of peripheral defocus is related to the defocus position of the retina. The closer to the fovea, the higher the weight and the better the effect. Correspondingly, the central optical zone of the lens should be smaller. The existing 8-9mm central transparent zone has the opportunity to be further reduced, and the corresponding central defocus fill rate will be enhanced and improved.

[0003] Existing lens designs all align the optical center of the lens with the center of the defocus zone. This means the lens' optical center is at the center of the defocus zone. This design offers the advantage of maintaining the same defocus starting distance in all directions. However, it doesn't advance the defocus starting point in the temporal field of view, nor does it enhance temporal defocus. In theory, this could be improved by creating an eccentric design, shifting the gaze point away from the center of the defocus zone and toward the temporal side. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the purpose of this application is to provide a dynamic defocus microlens structure lens with an eccentric design, which achieves dynamic defocus by designing the optical center and the defocus center inconsistently and the nasal temporal defocus amount asymmetric, thereby alleviating the problem of decreased myopia control effect after long-term wear.

[0005] The above-mentioned application objectives of this application are achieved through the following technical solutions:

[0006] A dynamic defocus micro-lens structure lens with an eccentric design comprises a defocus ring arranged on the lens, a transparent optical zone is provided at the center of the defocus ring, and the optical center of the lens deviates from the center of the defocus ring.

[0007] As a further technical solution of the present application: the optical center of the lens moves 1mm-3mm from the center of the defocus ring to the temporal side of the human body, and then moves 1mm-3mm downward.

[0008] As a further technical solution of the present application: the diameter of the transparent optical zone is 6 mm, and the diameter of the defocus ring is 40 mm-60 mm.

[0009] As a further technical solution of the present application: the defocus ring includes a plurality of concentrically arranged single rings, and each of the single rings includes the same number of defocus arc segments and arc segment gaps.

[0010] As a further technical solution of the present application: the defocus ring has a total of 17-90 single rings, and the width of the single ring is 0.3mm-1.0mm.

[0011] As a further technical solution of the present application: each single ring is provided with 6 defocused arc segments and 6 arc segment gaps, and the angles of each defocused arc segment and each arc segment gap corresponding to the structural center are 10°-50° and 50°-10° respectively, and the total of the two is 60°, forming an array.

[0012] As a further technical solution of the present application: the middle of the defocused arc segment is a cylindrical annular surface, and the two ends are made into spherical transition connections, and the curvature radius of the spherical surface is equal to the curvature radius of the annular surface interface.

[0013] As a further technical solution of the present application: the lens is designed to distinguish between the left and right eyes, wherein the defocus amount of the lens of the defocus ring close to the temporal side of the human body is greater than the defocus amount of the lens close to the nasal side of the human body.

[0014] As a further technical solution of the present application: the defocus arc segment uses a semicircular cylindrical spherical surface. If the defocus arc segment crosses the center line, the defocus amount is based on the end with a larger area, and the same defocus arc segment has the same defocus amount.

[0015] As a further technical solution of the present application: the image seen in the area of ​​the arc segment gap is a clear image;

[0016] The defocus arc segment is a convex lens structure or a concave lens structure, which can provide multiple different refractive powers, so that the image seen in the peripheral area except the transparent light area becomes blurred.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. This application discloses a dynamic defocus microlens lens with an eccentric design. The central transparent optical zone is designed to have a smaller diameter. Existing designs generally range from 8-9mm, while this design is 6mm. By offsetting the optical center of the lens from the center of the defocus ring and utilizing the binocular eccentric design, the initial defocus distance on the temporal side is shortened when the eye rotates, while the fellow eye still maintains a clear visual zone of nearly 4mm. This minimizes binocular fusion and ensures clear vision.

[0019] 2. The defocus of the nasal and temporal microlens structures of the lenses of this application is different. According to the physiological structure of the normal human eye and the research on retinal defocus after wearing this lens, the temporal visual field (nasal retina) requires a higher defocus to achieve a better effect. Combined with the function of binocular fusion, increasing the defocus of the temporal side of the lens is expected to achieve a higher defocus without significantly affecting peripheral vision and wearing experience.

[0020] 3. The present application designs the peripheral defocus lens to be asymmetrical on the nasal and temporal sides, thereby increasing the defocus amount on the temporal side, thereby optimizing the imaging effect of the fundus, so that after wearing it, the nasal and temporal sides of the fundus retina can achieve a basically consistent defocus effect.

[0021] 4. This application increases the center defocus fill rate from the current 23%-30% to approximately 41% by reducing the central transparent area and eccentrically designing the defocus center. Dynamic defocus can be achieved by asymmetric nasal and temporal defocus and misalignment between the optical center and the defocus center, thereby alleviating the problem of decreased control effectiveness after prolonged wear.

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean 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, or it can be internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0038] Example 1:

[0039] Reference Figure 1 and Figure 2 , is a dynamic defocus microlens structure lens with an eccentric design disclosed in the present application, including a defocus ring 2 arranged on the lens 1, a transparent optical zone 3 is provided in the center of the defocus ring 2, and the optical center of the lens 1 deviates from the center of the defocus ring 2. The optical center of the lens moves 1mm-3mm from the center of the defocus ring 2 to the temporal side of the human body, and then moves 1mm-3mm downward. In this embodiment, the optical center of the lens 1 preferably moves 1mm from the center of the defocus ring 2 to the temporal side of the human body, and then moves 1mm downward. The diameter of the transparent optical zone 3 is 6mm, and the diameter of the defocus ring 2 is 40mm-60mm. In this embodiment, the diameter of the defocus ring 2 is preferably 40mm.

[0040] To improve the myopia control effect of the lens 1, this application uses a smaller transparent optical zone 3 (6mm) and moves the optical center of the lens 1 1mm temporally and then 1mm downward from the center of the defocus ring 2. This ensures that when each eye moves temporally, defocus begins within 2mm of movement, while the opposite eye remains clear (the corresponding nasal area of ​​the opposite eye has a transparent zone of nearly 4mm). Compared with the current design, which has a transparent zone of nearly 4mm in all directions, this design has a higher defocus weight.

[0041] Reference Figure 3 and Figure 4 , the defocus ring 2 is a concentric defocus ring 2 cylindrical lens, and the defocus ring 2 includes a plurality of concentrically arranged single rings 21, and each single ring 21 includes the same number of defocus arc segments 211 and arc segment gaps 212. That is to say, a plurality of defocus arc segments 211 are evenly spaced to form a single ring 21, and a plurality of concentrically arranged single rings 21 constitute the defocus ring 2 in the present application, wherein the area of ​​the arc segment gap 211 does not have any additional structure, and the image seen is a clear image, and the structure of the arc segment gap 211 is the same as the structure of the substrate of the lens 1 itself, and has the same luminosity as the lens 1 itself. The defocus ring 2 has a total of 17-90 single rings 21, and the width of the single ring 21 is 0.3-1.0 mm. In this embodiment, the defocus ring 2 has 35 single rings 21, and the width of each single ring 21 is 0.5 mm (see Figure 5 ).

[0042] Reference Figure 3 and Figure 4 Each single ring 21 is provided with 6 defocused arc segments 211 and 6 arc segment gaps 212. The angles of each defocused arc segment 211 and each arc segment gap 212 corresponding to the structure center are 10°-50° and 50°-10° respectively, and the total of the two is 60°, forming an array.

[0043] The center of the defocused arc segment 211 is a cylindrical annular surface, with both ends transitioning into spherical surfaces. The radius of curvature of the spherical surface is equal to the radius of curvature of the annular surface interface. This configuration combines the advantages of both a defocused lens and a cylindrical lens. The defocused area around the defocus ring 2 is kept constant at 50%, facilitating subsequent symmetrical complementarity between the two eyes.

[0044] The lens 1 is designed to distinguish between the left and right eyes, wherein the defocusing amount of the lens near the temporal side of the human body is greater than the defocusing amount of the lens near the nose side of the human body. Figure 1 and Figure 2Dynamic intelligent defocusing on the nasal temporal side uses the vertical direction of the gaze point as the boundary. The defocusing amount of the lens near the temporal side of the body (the temporal area, corresponding to the nasal retina) is 10D (black area), and the defocusing amount of the lens near the nasal side of the body (the nasal area, corresponding to the temporal retina) is 8D (red area). The defocusing arc segment 211 uses a semicircular annular cylindrical sphere. If the defocusing arc segment 211 crosses the center line, the defocusing amount is based on the larger end. The same defocusing arc segment 211 has the same defocusing amount.

[0045] The lens is divided into a nasal area and a temporal area, with the vertical line passing through the geometric center of lens 1 as the center. The defocus power of the microlens structure in the temporal area is greater than that in the nasal area. For example, the defocus power of the temporal area is +10D, and the defocus power of the nasal area is +8D.

[0046] The design of existing defocus lenses is almost always the same for both eyes. The two human eyes have the function of fusion, and the images of the two eyes can be fused into one in the brain. This application can use this feature to achieve a differentiated design for both eyes. The defocused area of ​​one eye corresponds to the transparent area of ​​the other eye, which can not only increase the clarity and comfort of wearing glasses, but also stimulate and exercise the binocular fusion function. The peripheral defocus lens is made into a nasotemporal asymmetric design, increasing the defocus amount on the temporal side, thereby optimizing the imaging effect of the fundus.

[0047] Specifically, the lens 1 includes a left lens and a right lens. The defocus ring 2 on the left lens has a complementary structural design to that on the right lens. For example, in the right lens, the innermost ring of the defocus ring 2 is a 10° defocus arc segment 211, separated by a 50° arc segment gap 212. Similarly, in the left lens, the innermost ring of the defocus ring 2 is a 10° arc segment gap 212, separated by a 50° defocus arc segment 211. By designing the defocus rings in the two lenses in a complementary manner, the defocused and transparent areas precisely complement each other in each eye's field of view, preventing visual disturbances caused by increased defocus and improving wearer clarity and comfort.

[0048] This ensures that no matter which direction the eyes turn, one eye will be in the transparent area, and the two eyes always maintain "complementary light and dark". The present application is a different design for both eyes, and the defocused area and the transparent area are precisely complementary in the fields of view of the two eyes in each direction, preventing visual distress caused by increased defocus, and improving wearing clarity and comfort. The design of existing defocus lenses is almost the same for both eyes. The two eyes of a person have the function of fusion, and the images of the two eyes can be fused into one in the brain. With this feature, the present application can use a differentiated design for both eyes, with the defocused area of ​​one eye corresponding to the transparent area of ​​the other eye, which can not only increase the clarity and comfort of wearing glasses, but also stimulate and exercise the image fusion function of both eyes.

[0049] In this embodiment, the microlens structure of the defocus ring 2 is designed to be located on the front surface of the lens 1. The idea of ​​this application is to add an additional microlens structure to the front surface of the original lens 1. The microlens structure is a defocus arc segment 211 with a convex lens structure or a concave lens structure, and the arc segment gap 212 is the so-called microlens gap. No structure is added, and the lens itself is retained.

[0050] In the left-eye lens or the right-eye lens, in this embodiment, taking the left-eye lens as an example, the microstructure ring zones of the defocus ring 2 are divided into odd-numbered ring zones and even-numbered ring zones, and are distributed sequentially from the inside to the outside;

[0051] In the singular ring;

[0052] The first ring belt is arranged in 6 arrays in a clockwise direction starting from 90°, and each array has an angle of 60°;

[0053] The next odd-numbered ring is 10° clockwise from the previous odd-numbered ring and has 6 arrays in a clockwise direction.

[0054] The length of the defocused arc segment 211 of all odd-numbered annuli is the arc length on the aperture of the annular zone corresponding to the angle of 50°, and the remaining 10° is the arc segment gap 212 (left blank);

[0055] In the even-numbered ring belt;

[0056] The second ring belt starts from 90° and is distributed in 6 arrays in a clockwise direction, with each array having an angle of 60°;

[0057] The next even-numbered ring is 20° clockwise from the previous even-numbered ring, with 6 arrays in a clockwise direction.

[0058] The microstructure length of the defocused arc segments 211 of all even-numbered annular zones is the arc length on the annular zone aperture corresponding to an angle of 10°, and the remaining 50° is the arc segment gap 212 (left blank).

[0059] In the left eye lens or the right eye lens, in this embodiment, taking the right eye lens as an example, the microstructure ring zones of the defocus ring 2 are divided into odd-numbered ring zones and even-numbered ring zones, and are distributed sequentially from the inside to the outside;

[0060] In the singular ring;

[0061] The first ring belt has 6 arrays distributed in a clockwise direction starting from 100°, and each array has an angle of 60°;

[0062] The next odd-numbered ring is 10° clockwise from the previous odd-numbered ring and has 6 arrays in a clockwise direction.

[0063] The length of the defocused arc segment 211 microstructure of all odd-numbered annuli is the arc length on the aperture of the annular zone corresponding to the angle of 10°, and the remaining 50° is the arc segment gap 212 (left blank);

[0064] In the even-numbered ring belt;

[0065] The second ring belt starts from 80° and is distributed in 6 arrays in a clockwise direction, with each array having an angle of 60°;

[0066] The next even-numbered ring is 20° clockwise from the previous even-numbered ring, with 6 arrays in a clockwise direction.

[0067] The microstructure length of the defocused arc segments 211 of all even-numbered annular zones is the arc length on the annular zone aperture corresponding to an angle of 50°, and the remaining 10° is the arc segment gap 212 (left blank).

[0068] In each single ring 21 , the overall array of each defocused arc segment 211 and each corresponding arc segment gap 212 corresponds to an arc length of 30°-90°.

[0069] The above is one example. If the arc length corresponding to the overall array of a single ring is 60°, in addition to the above embodiments, the others include: if the microstructure length of the odd-numbered ring defocused arc segment 211 is the arc length corresponding to the ring aperture at a 20° angle, then the microstructure length of the even-numbered ring defocused arc segment 211 is the arc length corresponding to the ring aperture at a 40° angle. Similarly, the microstructure of the 30° odd-numbered ring defocused arc segment 211 corresponds to the microstructure of the 30° even-numbered ring defocused arc segment 211, maintaining the microstructure of the defocused arc segment 211 and the overall array of the blank area corresponding to an arc length of 60°. That is to say, in each single ring 21, the overall array of each defocused arc segment 211 and the corresponding arc segment gap 212 corresponds to an arc length of 60°.

[0070] Lens 1 is provided with horizontal positioning markings. During actual production of this product, it is necessary to add left and right eye markings and horizontal positioning markings to lens 1 to facilitate subsequent assembly. Segment gap 212 is a structure inherent to the lens 1 substrate, ensuring a clear image in the transparent light zone. Defocus segment 211 is a convex or concave lens structure, providing multiple diopters to correct for retinal hyperopic or myopic defocus, blurring the image in the peripheral area outside the transparent light zone.

[0071] Reference Figure 12 , is a diagram showing the arrangement of the defocus rings 2 on the left and right lenses 1 of this application. In this embodiment, the defocus arc segment 211 is a convex lens structure that can provide multiple different diopters to correct the retinal hyperopia defocus, making the image seen in the peripheral area except the transparent light area blurred. In the actual production process, strictly follow Figure 12Based on the parameters of the lens 1 design, a metal mold is first made for injection molding to create the preset front surface of the lens 1. This process requires the addition of invisible horizontal markings. The resulting blank lens 1 is then lathed to the preset light intensity according to the customer's prescription, and finally cut and assembled into the spectacle frame. During the assembly process, the horizontal angle, left and right eye spacing, and pupillary distance and height are checked to ensure the perfect fit.

[0072] Reference Figure 6 The lens 1 of the present application adopts an eccentric dynamic defocus and mortise and tenon structure design. The maximum range of the optical center area is 6mm, the horizontal temporal side is <2mm, and the horizontal nasal side is <4mm. While ensuring clear central vision, the edge produces defocused images the fastest. The main characteristics are fast defocusing and large peripheral defocusing. The defocusing amount of the eye side is 10D spherical cylindrical lens (equivalent to a spherical lens greater than 5D), and the defocusing amount of the nasal side is 8D spherical cylindrical lens (equivalent to a spherical lens greater than 4D). Through 2:4 distance division and 1:5 area ratio, a mortise and tenon sensitive, clear and complementary fusion image is formed, which maximizes the defocus stimulation of retinal myopia and achieves the purpose of myopia prevention and control.

[0073] Reference Figure 7 and Figure 8 The defocused arc segment 211 and the spherical cylinder are combined. The defocus ring 2 on the lens 1 of the present application is a combination of the defocused arc segment 211 and the defocused spherical surface. The middle is an arc segment and the two cross sections are spherical surfaces, forming different projections of points and lines on the fundus.

[0074] Reference Figure 9 , the defocus center is designed to be eccentric. The lens 1 of this application has a fully asymmetric design. The optical center of the lens 1 is at the "black dot" position, and the defocus center is biased towards the "red dot" position on the upper side of the nose. The subject side quickly becomes a high-focus image at 2mm, and the nose side produces a defocus image at 4mm, forming a defocus stimulation in a shorter time and distance, which is better than the traditional large light area defocus design.

[0075] Reference Figure 10 The lens 1 of the present application is designed for binocular defocus and clear complementary design. No matter which direction it is turned, the defocus area of ​​one eye corresponds to the transparent area of ​​the other eye. Through the arc segments of different lengths of the left and right and odd and even circles, images with different brightness and darkness are formed, which just complement the brightness and clarity of the left and right eyes.

[0076] Reference Figure 11 Existing research shows that the defocus effect is most pronounced and has the highest weight within the 20° range of the macular area of ​​the fundus. This corresponds to a range of approximately 14m in diameter at the center of the lens 1, as calculated from simulated eye data. Therefore, the defocus lens fill rate in this area is particularly important. The central area of ​​the lens 1 of this application has a unique small radius design, resulting in a center fill rate as high as 41%, surpassing most defocus lenses. By reducing the central transparent area and eccentrically designing the defocus center, the center defocus fill rate can be increased from the current 23%-30% to approximately 41%.

[0077] in,

[0078] The implementation principle of this application is as follows: This application discloses a dynamic defocus micro-lens structure lens with an eccentric design, and the central transparent optical zone 3 of the design is smaller in diameter. The existing design is basically 8-9mm, and the present design is 6mm. At the same time, through the eccentric design of both eyes, the starting defocus distance of the temporal side is shorter when the eyes rotate, while the contralateral eye still maintains a transparent visual area of ​​nearly 4mm, and the binocular fusion state is small to ensure clear vision. In addition, the defocus amount of the nasal temporal micro-lens structure of the lens 1 is different. According to the physiological structure of the normal human eye and the research on retinal defocus after wearing this lens 1, the temporal visual field (nasal retina) requires a higher defocus to achieve a better effect. Combined with the function of binocular fusion, increasing the defocus amount of the temporal side of the lens 1 is expected to achieve a higher defocus amount without significantly affecting the peripheral vision and wearing experience.

[0079] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
