Description

Technical Field

[0001] This invention relates to the field of smart wearable devices and visual health technology, and in particular to an integrated device that highly integrates far-view display, audio interaction, and personalized correction into the form of glasses, while also being portable and practical, for the purpose of actively preventing myopia and relieving eye strain. Background Technology

[0002] Currently, the high incidence of myopia among teenagers and the widespread eye strain among office workers are becoming increasingly prominent problems. The core cause of these problems is that these individuals spend long periods of time staring at the close-range screens of electronic devices such as computers and mobile phones, causing the ciliary muscles of the eyes to remain in a state of continuous contraction and spasm, unable to relax naturally, thus inducing myopia or exacerbating eye strain.

[0003] To alleviate the aforementioned problems, existing technologies have developed devices such as "distant image projection screens" and "fog screens." Their core design principle is to project the image from a near-field screen to a distant location using optical principles, thereby reducing the accommodative burden on the ciliary muscle. However, these existing devices suffer from insurmountable technical drawbacks: firstly, they are bulky and require fixed locations, lacking portability and failing to meet the needs of mobile scenarios; secondly, their functionality is limited, only capable of image display, and cannot adapt to scenarios requiring audio interaction, such as video conferencing and online learning; thirdly, the refractive correction schemes are rudimentary, lacking sufficient correction accuracy and affecting the device's aesthetics, resulting in a poor user experience. Therefore, the market urgently needs a solution that can seamlessly integrate into modern life and workflows, combining healthy distant image vision, portability, functionality, and aesthetics. Summary of the Invention

[0004] Addressing the shortcomings of existing technologies, this invention aims to solve three major technical problems of current distance vision devices: bulky and inconvenient design, limited functionality and fragmented user experience, and rudimentary correction schemes with insufficient accuracy. It provides a highly integrated intelligent distance vision glasses and vision care method based on eyeglasses. This invention, through the selection of product form and the reconstruction and integration of functions, transforms passive viewing into active intervention, making healthy eye use a natural, convenient, and imperceptible daily behavior, while ensuring comfort and stability in various usage scenarios.

[0005] Technical solution

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart distance vision glasses system includes a magnetic base, a refractive lens assembly, a glasses frame, a distance vision optical module, and a magnetic clip. The magnetic base is fixed to the inside of the glasses frame.

[0008] Its core technical features are as follows: the distance imaging optical module is integrated within the eyeglass frame; the refractive corrective lens group is detachably attached to the magnetic base by magnetic force; and the refractive corrective lens group is located in the light output path of the distance imaging optical module. The magnetic base is embedded with a first magnetic element; the frame of the refractive corrective lens group is fitted with a magnetic clip, which is one or more second magnetic elements. The second magnetic elements and the first magnetic elements attract each other, achieving rapid positioning and stable connection.

[0009] Preferably, the far-image optical module uses Si-OLED display technology to generate high-definition images, and controls the propagation direction and path of light through freeform optical surface components and relay optical components.

[0010] Preferably, the far-image optical module is mounted on the outside of the refractive lens group for receiving image information from an external video source.

[0011] Preferably, the collimated light output from the far-image optical module is calibrated by the refractive lens group before entering the human eye, ensuring that the virtual far-image is clear and unobstructed.

[0012] Preferably, the lens body of the refractive lens group can be flexibly replaced according to the user's optometry prescription to achieve personalized and precise fitting.

[0013] Preferably, the device also includes a configurable flexible headband, the two ends of which are detachably connected to the ends of the two temples of the eyeglass frame via snaps or Velcro to improve wearing stability during user activity.

[0014] Preferably, the device further includes an audio input module, an audio output module, a power supply cable, and an integrated interface, all mounted on the temples of the eyeglass frame. The audio input module and the audio output module are internally integrated into the temples. The audio input module is used to collect the user's voice signal, and the audio output module is used to play audio signals to the user. The integrated interface is used to simultaneously receive video signals from an external host and transmit audio data. The power supply cable supplies power to the various power modules of the invention, and the power supply cable can be integrated with the integrated interface into a single structure.

[0015] Furthermore, the integrated interface is a USB Type-C interface that supports the DisplayPort Alternate Mode protocol, balancing transmission efficiency and versatility.

[0016] Furthermore, the audio output module includes a dual microphone array, and the audio output module is a bone conduction speaker located at the end of the temple of the eyeglass frame, in order to improve the sound quality of audio transmission and playback and reduce environmental interference.

[0017] Furthermore, it also includes an intuitive touch interaction module, which is mounted on the temples of the eyeglasses frame. This module receives touch input signals from the user and controls device functions based on these signals. Specifically, the touch interaction module may employ a capacitive linear touch slider, supporting common functions such as volume adjustment.

[0018] This invention also discloses a vision care method using intelligent far-vision glasses, employing the intelligent far-vision glasses described above, comprising the following steps:

[0019] S1. Connect the smart far-vision glasses to the external host that displays visual content through the integrated interface to ensure synchronous transmission of video signals and audio data and stable power supply to the device;

[0020] S2. When the user wears the smart far-viewing glasses, the far-viewing optical module converts the visual content output by the external host into a virtual far-viewing image with an equivalent viewing distance of 5 meters to infinity, and projects it into the user's eyes, so that the ciliary muscles of the user's eyes are in a natural relaxed state, thereby achieving myopia prevention and relief of eye fatigue.

[0021] Beneficial effects

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. Proactive health intervention and form factor advantages: The lightweight glasses form factor enables the function of distant vision, breaking the limitations of traditional distant vision devices on usage scenarios. Users can move and use it freely in various scenarios such as office, study, and home, transforming the tedious "eye protection training" into an imperceptible and continuous way of life and work.

[0024] 2. High integration of functions and unified experience: It perfectly integrates far-view display, high-definition audio communication and intuitive interaction into one device, which solves the cumbersome and disjointed experience caused by the separation of multiple devices such as screen, speaker, microphone and corrective lenses in traditional solutions, and provides an immersive and consistent user experience.

[0025] 3. Convenience of personalized correction: The magnetic design makes it easy and quick for users with different vision to share the device and accurately match their individual prescriptions. No tools are required for disassembly and assembly, which greatly enhances the product's practical value and user-friendliness.

[0026] 4. Stable and comfortable to wear: The optional flexible headband design fully considers the needs of different user groups (such as active teenagers), ensuring the stability of the device and the comfort of wearing it for a long time under different activity conditions.

[0029] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0030] The magnetic base 1 is fixed to the inside of the eyeglass frame 3. The refractive lens assembly 2 is detachably attached to the magnetic base 1 by magnetic force and is located in the light output path of the distance imaging optical module 4. The magnetic base 1 has a first magnetic component embedded in it. The frame of the refractive lens assembly 2 is equipped with a magnetic clip 5, which contains one or more second magnetic components. The clips attract each other by magnetic force to achieve quick positioning and fixation, making assembly and disassembly convenient and the connection stable.

[0031] The distant image optical module 4 is integrated within the eyeglass frame 3 and mounted on the outside of the refractive lens group 2. It is used to receive image information from external video sources (such as computers, tablets, televisions, etc.). It uses Si-OLED display technology to generate high-definition images and, through freeform optical surface components and relay optical components, controls the optical path to convert the image into a virtual distant image with an equivalent viewing distance of 5 meters to infinity. This collimated light, after being calibrated by the refractive lens group 2, clearly enters the human eye, ensuring visual effect and user comfort.

[0032] The refractive lens assembly 2 is embedded in the magnetic clip 5, adapting to the personalized needs of different users with refractive errors. The lens body of the refractive lens assembly 2 can be replaced according to the user's prescription, and the magnetic attraction enables quick positioning and assembly, achieving accurate and convenient personalized adaptation.

[0033] Furthermore, the present invention can be configured with a flexible headband to improve wearing stability during user activity. The present invention possesses technical advantages such as proactive health intervention, lightweight portability, integrated functions, and comfortable wearing, providing an integrated eye health solution for users who spend long hours on screens.

[0034] The far-image optical module 4 uses Si-OLED display technology to generate images and precisely controls the propagation direction and path of light through free-form optical surface components and relay optical components (such as lenses, light guide structures, etc.). Its specific working process is as follows: the image light output by the Si-OLED panel is optimized by the free-form optical surface components to achieve aberration elimination and precise light guiding, simulate the natural light path of distant objects, and finally make the human eye perceive the virtual far-image as being presented in a spatial position more than 5 meters away.

[0035] The present invention also includes an audio input module, an audio output module, a power supply cable 7, and an integrated interface 6. The audio input module, audio output module, power supply cable 7, and integrated interface 6 are all mounted on the temple portion of the eyeglass frame 3. The audio input module and the audio output module are built into the temple. The audio input module is used to collect the user's voice signal, and the audio output module is used to play audio signals to the user. The integrated interface 6 is used to simultaneously receive video signals from an external host and transmit audio data. The power supply cable 7 is used to supply power to the various power modules of the present invention, and the power supply cable 7 can be integrated with the integrated interface 6 to form a single structure. The integrated interface 6 specifically adopts a USB Type-C interface supporting the DisplayPort Alternate Mode protocol.

[0036] Preferably, the audio output module includes a dual microphone array and a bone conduction speaker to improve the sound quality of audio transmission and playback;

[0037] The audio output module is specifically mounted at the end of the temple of the eyeglass frame 3.

[0038] The present invention also includes an intuitive touch interaction module 8, which is mounted on the temple of the eyeglass frame 3. It is used to receive touch input signals from the user and to control the device functions based on the touch input signals. The touch interaction module 8 can solve the technical defects of traditional far-viewing devices, such as large size, fixed setting and single function. The touch interaction module 8 specifically adopts a capacitive linear touch slider. The user can generate volume adjustment commands by sliding the capacitive linear touch slider to control the audio volume.

[0039] Furthermore, the present invention may also include a flexible headband, the two ends of which are detachably connected to the ends of the two temples of the eyeglass frame 3, to provide additional fixed support for the user and improve wearing stability.

[0040] This invention also discloses a vision care method based on the above-mentioned intelligent far-vision glasses, comprising the following steps:

[0041] S1. Connect the smart far-vision glasses to an external host that displays visual content through the integrated interface 6.

[0042] S2. The user wears the smart far-view glasses, and the far-view optical module 4 converts the visual content output by the external host into a virtual far-view image with an equivalent viewing distance of 5 meters to infinity, and projects it into the user's eyes.

[0043] During daily work, study, or entertainment, users can keep their ciliary muscles in a relaxed state by watching the virtual distant image, thereby achieving proactive health intervention for myopia prevention and relief of eye fatigue.

[0044] This invention achieves a shift from "passive viewing to active intervention" through the above-mentioned technical solution, making healthy eye use a natural, convenient, and imperceptible daily behavior, while ensuring the wearing comfort and structural stability of the device in various usage scenarios; the shape design of the eyeglass frame 3 allows the smart far-vision glasses to be worn as a whole by the user for daily use, realizing active visual health intervention in mobile states.

[0045] Example 1: Office Scenario Application

[0046] The smart vision glasses of this embodiment have an ordinary eyeglass appearance, yet possess a technological feel and are lightweight, offering excellent wearing comfort. Internally, they integrate all the functional modules required by this invention. This embodiment is intended for programmers who need to participate in video conferences for extended periods, and its usage is as follows:

[0047] First, the user selects the appropriate refractive lens group 2 based on their own optometry data. The lens group 2 is then quickly and magnetically attached to the magnetic base 1 inside the glasses. The assembly process takes only a few seconds, and the device looks neat after assembly. Next, the user connects the smart vision glasses to their office computer via a USB-C cable. When the user looks at the lenses, the code and meeting software interface on the office computer screen are projected by the vision optical module 4 to form a clear virtual vision image. This virtual vision image has the same visual effect as a distant object outside a window, naturally relaxing the user's ciliary muscles. Simultaneously, the bone conduction speaker clearly transmits the colleague's voice signal to the user, and the dual microphone array ensures that the user's speech signal can be clearly picked up by the other party. During use, the user can seamlessly adjust the call volume by sliding their finger up and down on the touch slider on the temple. In this application, the user does not need to consciously operate the eye protection device; instead, the eyes continuously undergo "distance vision training" in a natural working state, achieving a balance between healthy eye use and work efficiency.

[0048] Example 2: Application in a home learning scenario (combined with a flexible headband)

[0049] As shown, this invention is particularly suitable for online learning scenarios for teenagers. This embodiment is applied to middle school students, and the usage process is as follows: The user connects the smart far-vision glasses to a tablet computer at home via an adapter. Considering the high activity levels of teenagers, to prevent head movement from causing virtual image jitter, the user is additionally equipped with a flexible, breathable elastic headband. The two ends of the elastic headband are securely and conveniently connected to the ends of the glasses temples via snaps or Velcro, forming a three-point support structure around the head, effectively improving wearing stability. After wearing the glasses equipped with customized refractive corrective lenses, the user can focus on learning in front of a clear virtual screen at an equivalent distance. Whether the user is sitting and listening or occasionally adjusting their posture, the glasses can stably fit the face, and their eyes are in a "far-vision" state with relaxed ciliary muscles throughout the entire course. The above design fully demonstrates the adaptability of this invention to different application scenarios and user needs, further strengthening the core technological advantage of "seamlessly integrating into daily life."

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
