Description

Technical Field

[0001] The invention belongs to the technical field of vision care, and in particular relates to a lens for preventing and delaying presbyopia and a training method thereof. Background Art

[0002] Presbyopia is an age-related eye disease that usually begins to appear around the age of 40 and gradually worsens with age. Its main manifestation is difficulty in seeing objects at close range, especially blurred vision when reading. This is because the lens gradually loses its elasticity and the adjustment ability of the ciliary muscle in the eye gradually decreases, resulting in the eye being unable to fully adjust the focal length to adapt to close-range work. Unlike refractive errors such as myopia, hyperopia and astigmatism, presbyopia is a gradual and irreversible physiological process. The root cause is the weakening of the eye's adjustment ability (i.e., the adjustment amplitude), which cannot automatically adjust the focus to the near distance like when it was young, resulting in insufficient near vision.

[0003] As the global population ages, the incidence of presbyopia continues to rise, impacting the quality of life of the elderly and placing a significant burden on society and the economy. Existing treatments primarily include reading glasses, progressive multifocal lenses, and surgical correction, but most of these methods can only partially alleviate near vision difficulties. Traditional presbyopia glasses also only partially help seniors address near vision difficulties. However, because presbyopia is a gradual physiological change, these methods have little effect on slowing its progression.

[0004] Therefore, it is necessary to propose a lens and a training method thereof for preventing and delaying presbyopia to solve the problems existing in the prior art.

[0005] The above information disclosed in this background technology is only for enhancing understanding of the background technology of the present invention and therefore it may contain information that does not constitute the prior art that is already known to a person of ordinary skill in the art. Summary of the Invention

[0006] The purpose of the present invention is to provide a lens and a training method for preventing and delaying presbyopia. By combining the special design of the lens with a training method based on the user's individual visual function, it aims to improve the visual quality of presbyopia and dynamically adjust and optimize according to the user's visual changes to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A lens for preventing and delaying presbyopia comprises a lens, wherein the upper area of ​​the lens is provided with a far vision area; at least one lens ring composed of multiple large lenses is provided outside the central area of ​​the far vision area; and the lower area of ​​the lens is provided with a near vision area.

[0009] Preferably, the inner diameter of the central area of ​​the far vision area is 9 to 15 mm.

[0010] Preferably, each large lens in the lens combination has a diameter of 3 to 12 mm and a diopter of -0.75D to -2.00D, and the multiple large lenses are distributed in a semi-annular shape with an annular spacing of 2 to 5 mm.

[0011] Preferably, the near vision area adopts an ADD design with a diopter of +0.50D to +3.50D.

[0012] A training method for preventing and delaying presbyopia, based on any one of the lens designs described above, comprising:

[0013] Based on the user's visual function information and individual factors, a data analysis model is used to tailor an initial training plan for the user;

[0014] Selecting training glasses equipped with lenses (1) according to the initial parameter settings in the initial training program, and having the user perform preliminary wearing adaptation;

[0015] After getting used to the wearing experience, the user wears the training glasses daily, fixes his / her sight on a preset target in front of him / her, and performs cross-head movements or eye movements up and down to enable the sight to continuously pass through different optical areas of the lens (1) to perform eye adjustment training;

[0016] Regularly conduct comprehensive visual function assessments on users, compare various visual function indicators before and after training, and judge the training effect;

[0017] Dynamically adjust training content and intensity based on training results, and optimize the initial training plan based on user feedback.

[0018] Preferably, the visual function information includes the user's eye position status, refractive status, binocular vision status, left and right eye degrees, accommodation function test results and convergence function test results, which are obtained through a comprehensive visual function test of the user; the individual factors include the user's age, eye habits, and occupational characteristics, which are obtained through a questionnaire survey of the user.

[0019] Preferably, the eye adjustment training is performed by performing a cross movement of the head or an up and down eye movement exercise to continuously pass through different optical areas of the lens (1), including:

[0020] The user fixes his sight on a preset target in front of him, and turns his head left and right, and raises and lowers his head up and down so that his sight passes through different optical areas of the lens (1) in sequence, thus performing eye adjustment training;

[0021] The user fixes his eyes on a preset target in front of him and moves his eyes up and down to move his eyes through the far vision area (2) and the near vision area (4) in turn, thus training his eyes to adjust.

[0022] Repeat the above training process according to the training times or time settings in the initial training plan.

[0023] Preferably, dynamically adjusting the training content and intensity according to the training effect and optimizing the initial training plan in combination with user feedback includes:

[0024] Based on the user's biofeedback data, a CNN and LSTM model is used to predict the user's visual fatigue level and generate personalized training interval and rest recommendations;

[0025] Use adaptive learning algorithms to gradually increase the intensity of training content and optimize the effect of improving users' visual function;

[0026] Adaptive learning algorithm dynamically adjusts the formula:

[0027] P adjusted =αP current +(1-α)P target

[0028] Where, P adjusted is the adjusted training parameter, P current is the training parameter of the current user, P target It is a recommended parameter calculated according to the training goal or visual improvement goal. α is an adaptive weight coefficient that is gradually updated as the training progresses.

[0029] Introducing reinforcement learning to adjust training content and intensity based on real-time user feedback, gradually guiding users to adapt to different visual stimuli;

[0030] Q-learning optimization formula:

[0031]

[0032] Where, Q(s t ,a t ) is the Q value of taking an action in the current state, r t is the immediate reward, γ is the discount factor, is the maximum Q value in the next state;

[0033] Preferably, the method further comprises:

[0034] Use augmented reality or virtual reality technology to provide users with an immersive visual training environment;

[0035] By integrating the cloud system, a long-term archive of the user's visual function and training data is established. Combined with the intelligent recommendation algorithm, the corresponding training content and intensity are recommended according to the user's current visual function status.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] This invention effectively meets the visual needs of different users at different distances by designing a far vision area above the lens, a large lens group outside the central area, and a near vision area below. The large lens group in the far vision area, through precise lens parameter design, helps delay the onset of presbyopia in middle-aged and elderly users, while the ADD design in the near vision area reduces accommodation during close-up use, thereby improving visual fatigue and discomfort.

[0038] This invention customizes an initial training plan for each user based on their visual function information and individual differences, combined with a professional data analysis model. It also optimizes the training process and enhances visual function improvement by dynamically adjusting training content and intensity, combined with biofeedback and real-time feedback from the user. Furthermore, by incorporating adaptive learning algorithms and reinforcement learning mechanisms, the intensity and content of training are gradually adjusted as training progresses, making training more accurate and efficient, thereby providing each user with a personalized, scientific vision training plan.

[0039] In summary, this invention combines specially designed lenses with training methods based on individual visual function, enabling personalized training programs and visual function assessments. Dynamic adjustments are made based on user feedback and training results, effectively preventing and delaying the progression of presbyopia. This approach not only addresses the limitations of traditional lenses but also enhances training effectiveness and slows the progression of presbyopia through personalized training.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] It should be noted that the drawings are schematic and not drawn to scale. For clarity and convenience, the relative sizes and proportions of parts shown in the drawings may be exaggerated or reduced in size. Any dimensions are illustrative only and are not intended to be limiting. Identical structures, elements, or components appearing in two or more drawings are denoted by the same reference numerals to indicate similar features.

[0050] Example 1:

[0051] See also Figure 1 As shown, a lens for preventing and delaying presbyopia includes a lens 1, wherein the upper area of ​​the lens 1 is provided with a far vision area 2, and the inner diameter of the central area is 9 to 15 mm; at least one lens ring 3 composed of multiple large lenses is provided outside the central area of ​​the far vision area 2; the lower area of ​​the lens 1 is provided with a near vision area 4, which adopts an ADD design and has a refractive power of +0.50D to +3.50D.

[0052] Specifically, when a person wears glasses with this lens 1, they look forward through the far vision area 2, and their eyes turn to the large lens area to stimulate the contraction of the ciliary muscles of the eyes to produce accommodation. While wearing the glasses, accommodation training is performed, which improves the accommodation function of the human eye, thereby improving the accommodation function of presbyopia. When reading, writing, and other close-up use of the eyes, they look through the near vision area 4. The progressive multifocal design of its ADD area can reduce the need for accommodation when looking at close objects, thereby alleviating the symptoms of presbyopia. The advantage of this design is that the far vision area 2 is used for distant vision, while the large lens can improve accommodation. In daily use, when the eyes turn back and forth to look at different targets, accommodation training can also be continuously performed, thereby effectively slowing down the decline of accommodation function and delaying the onset of presbyopia. The ADD area of ​​the near vision area 4 is used for close vision, which can alleviate the symptoms of presbyopia, thereby playing a role in alleviating the symptoms of presbyopia and improving presbyopia.

[0053] Specifically, each large lens has a diameter of 3 to 12 mm and a diopter of -0.75 D to -2.00 D, and the multiple large lenses are distributed in a semi-annular shape with an annular spacing of 2 to 5 mm.

[0054] Furthermore, Figure 1 The semi-annular arrangement formed by the multiple large lenses is merely one possible semi-annular arrangement for achieving the functionality of the lens 1 in this embodiment. This semi-annular arrangement can be achieved by combining a single ring of large lenses or multiple rings of large lenses, with the specific number of rings determined by the diameter of the selected large lenses. Alternatively, a continuous or discontinuous lens arrangement may be employed. The same applies to the other embodiments described below.

[0055] Specifically, the lens 1 can be designed to be circular or rectangular.

[0056] As can be seen above, the design of this lens 1, through its combination of a progressive multifocal design in the distance vision zone 2, the lens zone, and the near vision zone 4, effectively enhances the eye's accommodation function and alleviates presbyopia symptoms. By stimulating the ciliary muscle to contract for accommodation training, the eye's accommodation ability is enhanced, while the need for accommodation during close-up use is reduced, thereby improving presbyopia symptoms. The lens zone design further slows the progression of presbyopia by regulating the eye's accommodation function, while the ADD design in the near vision zone 4 helps alleviate visual fatigue caused by presbyopia, ultimately achieving the desired effect of alleviating and improving presbyopia.

[0057] Example 2:

[0058] See also Figure 2 As shown, based on the core design framework of the above-mentioned embodiment 1, the lens ring 3 of the lens 1 in this embodiment 2 adopts an alternating lens structure form in which, from the inside to the outside, the first ring is a large lens 31 (training adjustment), the second ring is a positive lens 32 (relaxation adjustment), and the third ring is a large lens 33 (training adjustment), also forming a semi-annular distribution, and the ring spacing is slightly smaller than the ring spacing of the lens combination 3 in the above-mentioned embodiment 1 (0.5~1.0mm).

[0059] When the user looks at a target object, head movement causes the eyes to sequentially pass through different diopter rings, creating dynamic accommodation training. For example, when the eyes turn left, they pass through the first ring (training ciliary muscle contraction). Further leftward movement will lead to the second ring (training relaxation), and further leftward movement will lead to the third ring (training ciliary muscle contraction). Training continues as the eyes turn left and right.

[0060] The refractive power range of the large lens can be extended to -2.50D, and the +1.00D to +2.50D range is innovatively added to the positive lens to form a "negative-positive-negative" alternating stimulation mode, enhancing the effect of regulatory sensitivity training.

[0061] Specifically, the lens 1 can be designed to be circular or rectangular.

[0062] Example 3:

[0063] See also Figure 3 As shown, based on the core design framework of the above-mentioned embodiment 1, the front surface of the lens 1 in this embodiment 3 maintains a single vision zone, and the back surface adopts a double-layer partition design: the upper annular area is embedded with a large lens (-1.00D to -3.00D, with a diameter of 5 to 10mm), and the lower near vision area is processed with a positive lens (+1.00D to +3.00D). When the user looks at the target object, the head movement drives the eyes to pass through the different diopter annular areas in turn, forming a dynamic adjustment training. Or turn the eyes up and down to perform adjustment training similar to the reverse beat, turning the eyes up to train the adjustment, and turning the eyes down to relax the adjustment. For example: when the upper large lens is -2.00D and the lower near vision area is +2.00D, turning the eyes up and down is similar to using a ±2.00D reverse beat for adjustment training.

[0064] During training, focus on a target or sight card in front of you. For example, if you look at a fixed sight card, then slowly raise your head. This will cause your line of sight to shift downward, allowing you to relax and adjust through the positive lens area below. Once you see clearly, slowly lower your head again. This will cause your line of sight to pass through the negative lens area above the lens, allowing you to adjust your vision. Repeating this exercise multiple times daily can effectively improve your accommodation function.

[0065] Adding a positive lens setting in the near vision zone 4 reduces ciliary muscle fatigue by reducing the contraction amplitude of the ciliary muscle, and alleviates near vision fatigue caused by insufficient accommodation when using the eyes at close range.

[0066] Example 4:

[0067] See also Figure 4 As shown, based on the core design framework of the above-mentioned embodiment 1, the near vision area 4 of the lens 1 in this embodiment 4 adopts the "free-form surface" progressive multifocal technology, and the diopter of multiple progressive zones increases smoothly from top to bottom. The back surface is customized according to individual eye test data (including near pupil distance, ADD value, etc.) to form a smooth refractive power transition zone (length 10 to 14 mm).

[0068] The lens has a built-in "intelligent partitioning" design. When the patient's line of sight naturally moves downward to read, the asymptotic channel matches the eye distance, and the degree transitions smoothly during eye movement without causing discomfort to the patient. It provides continuous clear vision within the range of 30 to 50 cm, reduces the need for adjustment, and increases daily eye comfort.

[0069] Specifically, the lens 1 can be designed to be circular or rectangular.

[0070] Example 5:

[0071] See also Figure 5-Figure 6 As shown, based on the core design framework of the above embodiment 1, the lens ring 3 of the lens 1 in this embodiment 5 can also adopt a polygonal lens design (such as an octagon, hexagon, pentagon, etc.), and can be a continuous design (such as Figure 5 , a semi-ring consisting of nine large lenses), or a discontinuous design (such as Figure 6 , an example of possible distribution of discontinuous design of large lenses, and configuring the corresponding positive mirror according to the possible distribution of large lenses).

[0072] For example: User attaches Figure 6 When focusing on an object with lens 1 in the middle (①) distribution, head movement moves the eyes through the rings of different diopters, creating dynamic accommodation training. When the eyes turn left, they pass through the large lens (training accommodation) and then the positive lens (relaxing accommodation). Turning right, the eyes pass through the same set of large lenses (training accommodation) and then the positive lens (relaxing accommodation). Training continues as the eyes turn left and right.

[0073] In addition to the above-mentioned left-right rotation training and adjustment, users can also combine up-and-down eye movements to further enhance the ciliary muscle adjustment and relaxation training. When the eye is rotated upward, it passes through the large lens (training the ciliary muscle to contract), and then the eye is rotated downward to the ADD area, where the ciliary muscle relaxes. Training continues with the up-and-down rotation.

[0074] Furthermore, Figure 6 The discontinuous distribution of multiple large lenses is merely an example of various possible discontinuous large lens position distributions for achieving the functions of lens 1 in this embodiment. This discontinuous distribution can be achieved using a single large lens or a combination of large lenses and positive lenses. The specific design of the large lenses (and whether or not a positive lens is configured) is determined by the selected large lens diameters and position distribution.

[0075] Example 6:

[0076] See also Figure 7 As shown, a training method for preventing and delaying presbyopia, based on the design of the lens 1 in the above embodiment 1, includes the following steps:

[0077] Based on the user's visual function information and individual factors, a data analysis model is used to tailor an initial training plan for the user;

[0078] Among them, visual function information is obtained through comprehensive visual function testing of users, including the user's eye position, refractive status, binocular vision status, left and right eye power, accommodation function test results, and convergence function test results; individual factors are obtained through questionnaire surveys of users, including user age, eye habits, and occupational characteristics;

[0079] Furthermore, by combining the user's visual function information and individual factors, a professional data analysis model is used to tailor a personalized initial training plan. This plan helps improve training effectiveness. Personalized adjustments can effectively prevent and delay visual decline, improving the user's visual health.

[0080] Selecting training glasses with lens 1 according to the initial parameter settings in the initial training plan, and having the user initially wear and adapt to the glasses;

[0081] The initial parameter settings include lens power, frame size, temple length and angle, and during the wearing adaptation process, based on the visual comfort information fed back by the user, specific glasses parameters are dynamically adjusted during subsequent training to better meet the user's visual needs. Example:

[0082] During the first 3 to 5 days of wearing, wear the training glasses for 1 to 2 hours every day, and perform simple daily visual activities, such as reading a short article or looking at a distant scene, to allow your eyes to gradually adapt to the changes in visual accommodation brought about by the specific glasses.

[0083] On the 6th to 10th day of wearing, gradually increase the wearing time to 3 to 4 hours per day. The continuous wearing time can be appropriately extended, but not more than 1.5 hours each time, with a 10 to 15 minute break in between. Try to do some activities that require a certain level of visual accommodation, such as using electronic devices to browse information, doing simple handicrafts, etc.

[0084] During subsequent training and in daily life, develop the habit of wearing training glasses for a long time. Except for special circumstances such as sleeping and strenuous exercise, try to wear them all day long to keep your eyes in a specific visual adjustment environment and consolidate the adaptation effect.

[0085] After getting used to the wearing experience, the user can wear the training glasses daily, fix their gaze on a preset target in front of them, and perform cross-head movements or eye movements up and down to ensure that their gaze continuously passes through different optical areas of the lens 1, thus training their eyes to adjust.

[0086] The user fixes his eyes on a preset target in front of him, and turns his head left and right, and up and down, so that his eyes pass through different optical areas of the lens 1 in sequence, thus training his eyes to adjust.

[0087] The user fixes their gaze on a preset target in front of them and moves their eyes up and down to move their gaze through the far vision area 2 and the near vision area 4 in sequence, thus training their eyes to adjust.

[0088] Repeat the above training process according to the number of training times or time settings in the initial training plan.

[0089] Post-training evaluation and adjustment steps:

[0090] After each training session, users will perform 5 to 10 minutes of eye relaxation exercises, such as closing their eyes, applying warm compresses to the eyes, and looking into the distance, to relieve eye fatigue caused by training.

[0091] Collect user feedback during training, such as whether they feel uncomfortable or have visual fatigue;

[0092] Record user feedback on training difficulty and effect to provide a basis for subsequent training adjustments.

[0093] Furthermore, through sight adjustment training targeted at different optical zones, users can improve their eye accommodation and vision health. Regular head movements, eye movements, and sight adjustment enhance eye muscle flexibility, relieve visual fatigue, and prevent myopia or vision loss. Post-training eye relaxation and feedback collection effectively reduce eye discomfort and enhance training effectiveness.

[0094] Regularly conduct comprehensive visual function assessments on users, compare various visual function indicators before and after training, and judge the training effect;

[0095] Dynamically adjust training duration and intensity based on training results, and optimize initial training plans based on user feedback;

[0096] Based on the user's biofeedback data, a CNN and LSTM model is used to predict the user's visual fatigue level and generate personalized training interval and rest recommendations;

[0097] Use adaptive learning algorithms to gradually increase the intensity of training content and optimize the effect of improving users' visual function;

[0098] Introducing reinforcement learning to adjust training content and intensity based on real-time user feedback, gradually guiding users to adapt to different visual stimuli;

[0099] Furthermore, by regularly assessing the user's visual function and dynamically adjusting training content and intensity based on feedback, we provide personalized visual training programs. Combining CNN and LSTM models, we predict visual fatigue and generate rest recommendations, ensuring the scientific and effective nature of training. Adaptive learning algorithms and reinforcement learning mechanisms gradually optimize training results and guide users to adapt to different visual stimuli.

[0100] Use augmented reality or virtual reality technology to provide users with an immersive visual training environment;

[0101] By integrating the cloud system, a long-term archive of the user's visual function and training data is established. Combined with the intelligent recommendation algorithm, the corresponding training content and intensity are recommended according to the user's current visual function status.
