Description

Technical Field

[0001] The present invention relates to the technical field of vision correction, and more particularly to a novel myopia and hyperopia correction device. Background Art

[0002] With the increasing prevalence of myopia and hyperopia, vision correction methods are primarily divided into surgical and non-surgical options. Surgical methods, such as LASIK and SMILE, can quickly correct vision but may cause irreversible side effects such as dry eye, visual fatigue, and corneal complications. On the other hand, traditional non-surgical methods, such as spectacles and contact lenses, only provide visual correction while they are worn but are unable to effectively restore the function of the eye's accommodative muscles.

[0003] In recent years, accommodative lenses (such as progressive addition lenses) and vision training methods have been increasingly used to correct myopia and hyperopia. However, these methods primarily rely on passive correction, failing to fundamentally improve the function of the lens's accommodative muscles and ultimately restore vision. The current market lacks an intelligent, non-surgical correction device that can actively train the eye's accommodative muscles to correct myopia and hyperopia.

[0004] Therefore, it is an urgent problem for those skilled in the art to propose a new type of myopia and hyperopia correction device to solve the difficulties existing in the prior art. Summary of the Invention

[0005] In light of this, the present invention provides a novel myopia and hyperopia correction device. This device improves the accommodative ability of the eye lens by dynamically adjusting lens thickness and actively training eye muscles, thereby achieving non-surgical restoration and correction of myopia and hyperopia. This device not only provides real-time vision correction while worn but also promotes reverse deformation training of the eye muscles through long-term use, ultimately improving or even curing myopia and hyperopia.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A novel myopia and hyperopia correction device includes: an electronic iris detector, a battery module, a mechanically driven focusing lens, and a computing chip. The output end of the electronic iris detector is connected to the input end of the computing chip, the first output end of the computing chip is connected to the input end of the mechanically driven focusing lens, and the second output end of the computing chip is connected to the input end of the battery module.

[0008] Electronic iris detector: Located at the nose pad, it detects lens thickness using a first optical coherence tomography (OCT) sensor and a second optical coherence tomography (OCT) sensor, while also detecting the distance of objects the user is looking at using a first distance sensor and a second distance sensor.

[0009] Battery module: set in the glasses leg, used to provide power;

[0010] Mechanically driven focusing lens: It is set around the lens and is used to change the thickness of the mechanically driven focusing lens to correct vision;

[0011] Computing chip: set at the connection between the glasses frame and the glasses legs, used for data processing and controlling lens adjustment.

[0012] Optionally, the purpose of observation of the eye can be determined based on the size of the lens of the black eyeball displayed by the electronic iris detector. A larger lens indicates insufficient light, while a thinner lens indicates observation of a nearby object. Conversely, there is too much light or observation of a distant object.

[0013] Optionally, after the user wears the glasses, the first distance sensor and the second distance sensor collect the distance of the object in front of the user, and then determine the current shape state of the user's lens.

[0014] Optionally, the curvature of the mechanically driven focusing lens is adjusted mechanically.

[0015] Optionally, the mechanically driven focusing lens changes the thickness of the mechanically driven focusing lens through a built-in micro motor or a deformable material.

[0016] Optionally, the thickness of the mechanically driven focusing lens is dynamically adjusted according to the current usage scenario, that is, when the user is nearsighted, the thickness of the mechanically driven focusing lens is adjusted according to the distance of the object in front of the eye.

[0017] Optionally, the thickness of the mechanically driven focusing lens is adjusted according to the principle that the thickness decreases as the distance increases.

[0018] It can be seen from the above technical solutions that, compared with the prior art, the present invention provides a new myopia and hyperopia correction device, which has the following beneficial effects:

[0019] 1) By dynamically adjusting the lens thickness, myopic and hyperopic patients can achieve clear vision at different viewing distances;

[0020] 2) Enhance the ability to adjust the eye muscles through reverse deformation training, and fundamentally improve myopia and hyperopia;

[0021] 3) Combining optical coherence tomography (OCT) sensors and distance sensors to improve the real-time monitoring capabilities of eye health data;

[0022] 4) Adopting micro intelligent drive system to realize automatic adjustment of lenses and reduce human intervention;

[0023] 5) It breaks through the limitations of traditional frame glasses and contact lenses, while avoiding the potential risks of surgical correction, and has broad clinical application value and market prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] 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 part of the embodiments of the present invention, not all of the 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.

[0031] See also Figure 1As shown, the present invention discloses a novel myopia and hyperopia correction device, comprising: an electronic iris detector A, a battery module B, a mechanically driven focusing lens C, and a computing chip D. The output end of the electronic iris detector A is connected to the input end of the computing chip D, the first output end of the computing chip D is connected to the input end of the mechanically driven focusing lens C, and the second output end of the computing chip D is connected to the input end of the battery module B; wherein,

[0032] Electronic iris detector A: Located at the nose pad, it detects lens thickness using first and second optical coherence tomography (OCT) sensors A1 and A2, and the distance to objects viewed by the user using first and second distance sensors A3 and A4.

[0033] Battery module B: set in the temple of the glasses, used to provide power;

[0034] Mechanically driven focusing lens C: It is set around the lens and is used to change the thickness of the mechanically driven focusing lens C to correct vision;

[0035] Computing chip D: It is set at the connection between the glasses frame and the glasses legs, and is used for data processing and controlling lens adjustment.

[0036] Specifically, the pathogenic mechanisms of the two types of diseases are as follows:

[0037] Myopia: Due to an excessively long eye axis or strong corneal refractive power, light entering the eye focuses on the retina, causing distant objects to appear blurry. Common causes include genetics, prolonged close-up use, and insufficient light exposure.

[0038] Hyperopia: Due to a short eye axis or insufficient corneal refractive power, light entering the eye focuses behind the retina, causing nearby objects to be blurred. Common causes include congenital developmental deficiencies and a decrease in the lens's ability to accommodate changes due to aging.

[0039] This device works by controlling the muscles that control lens deformation. By inverting deformation, it allows the muscles to achieve more positive deformation capabilities. For example, the device allows the muscles to contract to their maximum extent, stretching the lens. After the device is discontinued, the muscles can still maintain a certain degree of contraction. Similarly, the device allows the muscles to relax to their maximum extent, compressing the lens. After the device is discontinued, the muscles can still maintain a certain degree of relaxation, and the lens can still maintain a certain thickness.

[0040] Through the above-mentioned muscle capacity shaping, the effect of fundamentally curing myopia and hyperopia can be achieved (the curing effect depends on the individual's physical condition, young people are better than the elderly, and the treatment effect of acquired diseases is better than that of congenital diseases).

[0041] Referring to Figure 3 and Figure 4 Fig. 1 and Fig. 2 are the near vision correction flowchart and far vision correction flowchart provided by the present application.

[0042] Further, the size of the lens of the black eyeball displayed by the electronic iris detector A is used to determine the observation purpose of the eye. If the lens becomes larger, it means that the light is not enough. If the lens becomes thinner, it means that the object is observed in the near distance. On the contrary, it means that the light is too large or the object is observed in the far distance.

[0043] Further, after the user wears the glasses, the distance of the object in front of the user is collected by the first distance sensor A3 and the second distance sensor A4, and then the shape of the lens of the current user is determined.

[0044] Further, the curvature of the mechanically driven focusing lens C is adjusted by a mechanical method.

[0045] Further, the mechanically driven focusing lens C changes the thickness of the mechanically driven focusing lens C by a built-in micro motor or a shape memory material.

[0046] Further, the thickness of the mechanically driven focusing lens C is dynamically adjusted according to the current use scenario. That is, when the user has myopia, the thickness of the mechanically driven focusing lens C is adjusted according to the distance of the object in front of the eye.

[0047] Further, the thickness of the mechanically driven focusing lens C is adjusted according to the principle that the farther the distance, the smaller the thickness.

[0048] Specifically, the implementation process is as follows: an electronic iris detector A is placed at the center of the nose bridge of the existing conventional glasses, the observation purpose of the eye is determined according to the size of the lens of the black eyeball in the electronic iris detector A (the lens becomes larger, which means that the light is not enough, the lens becomes thinner, which means that the object is observed in the near distance, and on the contrary, it means that the light is too large or the object is observed in the far distance), the two nose bridge positions of the electronic iris detector A are actually four sensors, which are the first optical coherence tomography OCT sensor A1 and the second optical coherence tomography OCT sensor A2 for detecting the left and right inner side of the lens, and the first distance sensor A3 and the second distance sensor A4 for detecting the distance of the object in front of the face.

[0049] Then, a battery module B is installed at the glasses leg of the frame, and a mechanically driven focusing lens C (Mechanical Focus-Adjustable Lenses) is installed around the lens. The mechanically driven focusing lens C is built-in with a micro motor or a shape memory material, and the curvature of the mechanically driven focusing lens C is adjusted by a mechanical method to achieve precise adjustment.

[0050] The computing chip D is arranged at the connection of the glasses frame and the glasses leg, so as to protect the core component from disconnection with the main body part. The computing chip D is used to realize dynamic adjustment of each module.

[0051] Specifically, the above glasses can obviously improve the myopia or hyperopia condition by playing an inverse deformation effect on the ciliary muscle of the eyeball through long-term wearing, but are not allowed to be carried during driving, and are carefully carried or carried with a special person in outdoor scenes.

[0052] In a specific embodiment, the following is included:

[0053] After the user wears the glasses, the first distance sensor A3 and the second distance sensor A4 collect the distance of the object in front of the user, and then judge the shape state of the user's lens. When the distance is 40 cm, the thickness of the lens is still relatively thin, and the reference international human lens thickness is determined as follows:

[0054] Hyperopia state (no adjustment, > 6m distance object): lens thickness is about 3.5-4.0mm (slightly changed due to individual differences);

[0055] Medium distance (about 50cm object): lens thickness is about 4.0-4.5mm;

[0056] Close distance (about 25cm object): lens thickness is about 4.5-5.0mm;

[0057] Extreme close distance (about 10cm object, maximum adjustment force): lens thickness can reach 5.0-5.5mm.

[0058] When the distance is within the above range, if it exceeds the corresponding thickness range, it is considered that the user has obvious myopia, and on the contrary, if it is thinner, it means that the user has hyperopia.

[0059] According to the above preliminary judgment information, it is determined whether the user's current disease type is myopia or hyperopia.

[0060] Then, the thickness of the mechanically driven focusing lens C is dynamically adjusted according to the current use scene, that is, when the user has myopia, according to the principle that the farther the distance of the object in front of the eye, the smaller the thickness increase (the actual increase process is to gradually thin the periphery (i.e. become a convex lens appearance) with the center of the lens as the plane reference), according to:

[0061] Within 50cm, the periphery of the mechanically driven focusing lens C is 0.1mm; from 50cm to 3m, the periphery of the mechanically driven focusing lens C is 0.2mm; more than 3m, the periphery of the mechanically driven focusing lens C is 0.3mm (calculated with the center of the lens as 0.35mm);

[0062] When the user is hyperopic, the accommodation process is opposite to that of myopia:

[0063] Within 50 cm, the mechanical drive focusing lens C periphery 0.6 mm; from 50 cm to 3 meters, mechanical drive focusing lens C periphery 0.5 mm; more than 3 meters, mechanical drive focusing lens C periphery 0.4 mm (0.35 mm calculated with the lens center).
