Description

Technical Field

[0001] The present invention belongs to the field of wearable home-grade medical devices, relates to a "digital eye", and specifically relates to an eye detection device. Background Art

[0002] Eye health is an essential component of human health, closely related to visual function, cognitive ability, and emotional state. However, due to various factors, including genetics, environment, lifestyle habits, and illness, many people face varying degrees of eye problems, such as myopia, astigmatism, strabismus, amblyopia, dry eyes, glaucoma, and cataracts. These problems not only affect people's visual quality and quality of life, but also increase social and economic burdens.

[0003] The eye is a biomechanical organ and the only organ in the human body that can directly see the neurovascular tissue. There are many biological indicators of the eye, such as eye morphological and structural indicators (such as changes in the morphology of the retina and pupil, changes in corneal and conjunctival blood vessels), functional indicators (such as intraocular pressure, corneal mechanical indicators, eye movement, attention, etc.). These indicators are closely related to the human body's system parameters (such as blood pressure, intracranial pressure, heart rate, blood biochemical indicators such as blood lipids), chronic disease indicators (such as cardiovascular and cerebrovascular diseases, kidney disease, mental illness), cognitive status, etc. Therefore, the use of these biological indicators can provide a digital model of "neuro-vascular-mechanical" indicators, which can be used for health management and disease monitoring of eye diseases and chronic diseases.

[0004] To detect and assess eye health, the commonly used methods are:

[0005] 1. Various eye examinations are performed using specialized instruments and equipment, such as vision tests, refraction tests, pupil tests, intraocular pressure tests, corneal curvature tests, and fundus examinations. These examinations typically require professional staff in hospitals or specialized institutions and are time-consuming and expensive. Furthermore, these examinations have limitations, such as the inability to monitor eye changes in real time and the inability to reflect eye performance in different environments and tasks.

[0006] 3. Application software based on mobile devices such as smartphones or tablets can use the camera, screen and other functions of the mobile device to perform some basic eye testing and training. However, due to limitations of factors such as the hardware performance, software quality, and subject operation of the mobile device, the accuracy and effectiveness of the testing and training cannot be guaranteed, and it cannot provide comprehensive monitoring of the eyes.

[0007] With the development of ophthalmic technology, the demand for portable, high-precision eye detection equipment is increasing. Existing eye detection tools are often single-function and bulky, making them difficult to use and carry around. Therefore, there is an urgent need for a portable "digital eye" device that can perform eye detection. Summary of the Invention

[0056] The present invention is described in further detail below with reference to the accompanying drawings:

[0057] The eye monitoring device provided by this invention can monitor eye health based on immersive media technologies (such as virtual reality (VR), augmented reality (AR), or extended reality (XR) technologies) and the detection of ocular biological indicators (including monitoring the subject's pupillary light reflex, iris, and fundus retinal photography, and even recording retinal neurovascular coupling responses under light stimulation). Furthermore, the invention can provide eye gaze training and strabismus and amblyopia training to help subjects improve their visual function and eye health.

[0058] Specifically, such as Figure 1 As shown, the eye detection device provided by the present invention includes: glasses, and a collection module 2 and a light source module arranged on the glasses. The collection module 2 is used to collect images and light signals; and the light source module is used for illumination.

[0059] The glasses can be existing VR glasses, AR glasses or XR glasses, and can be selected according to actual needs. VR glasses, AR glasses or XR glasses can simulate various visual environments to evaluate and train the user's visual response.

[0060] More specifically, the glasses include a frame comprising a frame 101 and temples 103 disposed on either side of the frame 101. The frame 101 is provided with two lenses 102 (VR, AR, or XR lenses). When the user puts on the frame, the two lenses 102 are positioned in front of the subject's left and right eyes, respectively. The lenses 102 are used to display images and information for virtual reality (VR), augmented reality (AR), or extended reality (XR). The front end of each temple 103 is connected to the side of the frame 101, and the rear end of each temple 103 is free.

[0061] Preferably, the frame is made of high molecular polymer and high-strength carbon fiber plastic to ensure structural stability and lightness. The glasses can provide an immersive experience, and in addition to the basic virtual reality experience, they also serve as the supporting structure of the entire device.

[0062] The acquisition module 2 includes two cameras with integrated optical sensors, which are respectively embedded in the upper part of the two lenses 102. For example, holes can be opened in the upper part of the two lenses 102, and the cameras are installed in the holes. The cables connected to the cameras are passed through the lenses 102 and connected to the controller in the temples 103. In this way, the cameras can be used to capture images of both eyes and various optical signals.

[0063] Preferably, the camera can adopt an existing high-definition camera, infrared camera, near-infrared camera, etc. with a built-in optical sensor (such as a CMOS (complementary metal oxide semiconductor) sensor or a CCD (charge coupled device) sensor). The camera first captures images from the target object, which can be generated by irradiation with a visible light or near-infrared light source, and outputs the image to other devices (such as a display, a computer, a printer, an external mobile phone device, etc.). The camera can shoot and record the subject's pupil, pupil light reflex, iris texture, fundus retinal blood vessels, etc. The pupil is photographed by a high-definition camera or an infrared camera, and the existing image processing algorithm is used to locate and segment the pupil area, and the pupil diameter is calculated. The pupil diameter refers to the diameter of the human pupil, which can reflect factors such as a person's emotions, attention, and light intensity. The pupil light reflex refers to the pupil's reaction to external light, which can reflect the person's nervous system function and eye diseases. The pupil light reflex can be photographed and observed by a near-infrared camera, using infrared light to illuminate the human eye and observe the degree of pupil contraction and dilation. Iris texture refers to the subtle lines on the human iris. It exhibits a high degree of individual variability and stability, enabling applications such as eye recognition. Iris texture can be captured and extracted using a high-definition camera or a near-infrared camera. Existing image processing algorithms are then used to locate and segment the iris region and extract its feature vectors. Retinal vessels in the fundus refer to the network of blood vessels in the retina, which can reflect a person's blood circulation and eye diseases. These vessels can be captured and recorded using a dedicated fundus camera, typically using white or green light to illuminate the eye and capture the reflected image.

[0064] The optical sensor first receives light signals from the target object or environment. These light signals can be visible light (e.g., red-free light) of varying wavelengths, infrared light, etc. The optical sensor converts the light signals into electrical signals and outputs them to other devices (e.g., the lens 102 display, external devices, etc.). These devices can process and analyze the electrical signals based on their intensity, frequency, phase, and other characteristics. The camera can capture minute details of the eye, enabling photography or short-term video recording of the cornea, anterior chamber, pupil, and retina.

[0065] The light source module includes a flexible rod 3 and a light-emitting component 4. The flexible rod 3 is a tubular structure that can be bent at will and has a certain flexibility. One end of the flexible rod 3 is connected to the front of the temple 103 (the end of the temple 103 close to the frame is the front end, the end away from the frame is the rear end, and the part close to the front end on the temple 103 is the front end), and the other end of the flexible rod 3 is a free end, and the light-emitting component 4 is connected to the free end of the flexible rod 3. Preferably, a light source module is connected to the front of each temple 103, so that the required lighting can be provided for two glasses at the same time. The flexible rod 3 is made of existing high-strength carbon fiber composite material to ensure lightness and high strength, ensure flexibility, and can be bent and rotated, so that it is easy to adjust to a variety of positions.

[0066] like Figure 2 As shown, the light-emitting component 4 includes: a shell, and a light source 404, a filtering mechanism 406, a slit grating 405 and a reflecting prism arranged in the shell. The light emitted from the light source 404 passes through the filtering mechanism 406, the slit grating 405 and the reflecting prism in sequence and is emitted to provide the required lighting for eye examination, that is, the emitted light is used to illuminate the position that needs to be illuminated, ensuring that the camera can capture a clear image.

[0067] The housing comprises a body 401, and a front end cap 402 and a rear end cap 403 disposed at both ends of the body 401. The body 401 is a hollow cylindrical structure with openings at both ends. The two end caps can be connected to the front and rear ends of the body 401 by existing connection structures such as threads or snaps to seal the openings at both ends of the body 401. A cable hole is provided in the middle of the lengthwise direction of the body 401. The free end of the flexible rod 3 is connected to the middle of the body 401, and the inner cavity of the flexible rod 3 is connected to the cable hole in the body 401. That is, when the flexible rod 3 is straightened, the central axis of the body 401 is perpendicular to the lengthwise direction of the flexible rod 3. The cable hole is provided in the middle of the body 401 to facilitate the cable in the light-emitting component 4 (the cable that powers the light source 404) to enter the inner cavity of the flexible rod 3 through the cable hole and pass through the inner cavity of the flexible rod 3 to connect to the controller in the temple 103.

[0068] like Figure 5As shown, a light exit hole 411 is formed in the front cover 402, a reflective prism is mounted within the light exit hole 411, and a light source 404 is disposed on the inner side of the rear cover 403. A cable connected to the light source 404 passes through the cable hole in the body 401 and then enters the inner cavity of the flexible rod 3. Within the inner cavity of the body 401, a slit grating 405 and a filter mechanism 406 are sequentially disposed from the front to the rear. Light emitted by the light source 404 passes through the filter mechanism 406 and the slit grating 405 in sequence before exiting from the reflective prism in the light exit hole 411. Preferably, the light source 404 is disposed on the upper portion of the inner side of the rear cover 403, and the light exit hole 411 is disposed on the upper portion of the front cover 402. In this way, the light emitted by the multi-spectral light source 404 is located above the central axis of the body 401.

[0069] The light source 404 uses an existing multi-spectrum LED, which can emit a variety of lights, such as cobalt blue light, red-free light, near-infrared light, etc., to provide the eyes with light of a specific wavelength band to meet different shooting needs. The wavelength of near-infrared light is between 0.7-1.4 microns, which is close to the range of visible light, but does not cause a visual reaction in the human eye. Near-infrared light is mainly used to detect the internal structure and function of the anterior segment of the eye and the retina of the fundus, such as blood vessels, nerve fiber layer, etc. Red-free light includes green light and blue light. The wavelength range of green light is generally between 500-570nm, and the wavelength range of blue light is generally between 450-495nm. Green light is mainly used to observe blood vessels and hemorrhagic lesions, and blue light is mainly used to observe changes in retinal nerve fibers and macula. It can further include a red light LED, located next to the multi-spectrum LED, which emits red light of 630-670nm for myopia treatment.

[0070] Furthermore, along the central axis of the body 401, a first semi-annular hole 407 and a second semi-annular hole 408 are opened in the middle of the wall of the body 401, which are coaxial with the body 401. The central angles of the two semi-annular holes are both 180 degrees, and the inner cavity of the body 401 is connected to the outside. The two semi-annular holes are located on the same side of the semi-cylindrical surface of the body 401, as shown in FIG. Figure 2 、 Figure 3-1 、 Figure 3-2 As shown (for the sake of clarity, Figure 3-1 、 Figure 3-2 The first and second positioning rings are not shown in the figure).

[0071] Further, such as Figure 4 As shown (for the sake of clarity, Figure 4Only the portion of the body between the two positioning rings is retained, and the other portions of the body are not drawn). A first positioning ring 4011 and a second positioning ring 4012 are provided in the middle of the inner cavity of the body 401, which are coaxial with the body 401. The two positioning rings are arranged opposite each other. For example, two annular steps coaxial with the body 401 can be provided in the middle of the inner cavity of the body 401. The first positioning ring 4011 and the second positioning ring 4012 are connected by the two annular steps respectively. The right end of the first positioning ring 4011 is connected to the first annular step, and the left end of the second positioning ring 4012 is connected to the second annular step. The outer diameters of the first positioning ring 4011 and the second positioning ring 4012 are both smaller than the inner diameter of the body 401. The first positioning ring 4011 is aligned with the first semi-annular hole 407, and the two have the same width; the second positioning ring 4012 is aligned with the second semi-annular hole 408, and the two have the same width. In this way, from the outside of the body 401 , half of the first positioning ring 4011 can be seen through the first semi-annular hole 407 , and half of the second positioning ring 4012 can be seen through the second semi-annular hole 408 .

[0072] A first blind hole (one end located on the outer surface of the first positioning ring is open and the other end is closed) perpendicular to the first positioning ring's axis is defined in the first blind hole. A first spring 4013 and a first locking ball 4014 are mounted within the first blind hole. One end of the first spring 4013 is fixedly connected to the bottom of the first blind hole, and the other end is connected to the lower end of the first locking ball 4014. When the first locking ball 4014 is pressed, it enters the first blind hole. When no external force is applied, the first spring 4013 pushes the first locking ball 4014 upward, positioning the upper half of the first locking ball 4014 outside the first blind hole. Preferably, the central axis of the first blind hole is aligned with the center of the first semi-annular hole 407, i.e., it is located on a straight line with a 90-degree radius of the first semi-annular hole 407.

[0073] Similarly, a second blind hole perpendicular to the axis of the second positioning ring 4012 is formed (one end located on the outer surface of the second positioning ring is open, and the other end is closed). A second spring 4015 and a second locking ball 4016 are installed in the second blind hole. One end of the second spring 4015 is fixedly connected to the bottom of the second blind hole, and the other end is connected to the lower end of the second locking ball 4016. When the second locking ball 4016 is pressed, it enters the second blind hole. When there is no external force, the second spring 4015 pushes the second locking ball 4016 upward, so that the upper half of the second locking ball 4016 is located outside the second blind hole. Preferably, the central axis of the second blind hole is aligned with the center of the second semi-annular hole 408, that is, it is located on a straight line with the 90-degree radius of the second semi-annular hole 408.

[0074] like Figure 6As shown, the slit grating 405 comprises a grating wheel, which includes a circular grating disk 4051 and a first annular flange 4052 located at the edge of the grating disk 4051 and perpendicularly connected to the grating disk 4051. The grating disk 4051 is provided with a plurality of slits 4053 of varying lengths and widths. The centerlines of the different slits 4053 lie at different radii of the grating disk 4051, i.e., the slits 4053 are radially distributed on the grating disk 4051. Preferably, three slits 4053 are evenly distributed on the upper half of the circular surface of the grating disk 4051, but more slits 4053 may be provided as needed. The inner diameter of the first annular flange 4052 matches the outer diameter of the first positioning ring 4011. The first positioning ring 4011 can be inserted into the first annular flange 4052, and the first annular flange 4052 can rotate relative to the first positioning ring 4011, thereby driving the entire grating disk 4051 to rotate relative to the first positioning ring 4011. A plurality of first grooves 4054 are formed on the inner surface of the first annular flange 4052. The inner diameter of the first grooves 4054 matches the diameter of the first locking ball 4014, and the upper half of the first locking ball 4014 can enter the first grooves 4054. Preferably, the first grooves 4054 correspond to the slits 4053 one-to-one. When viewed along the central axis of the grating wheel, the centerline of each first groove 4054 and the centerline of its corresponding slit 4053 are located on the same radius.

[0075] Furthermore, to facilitate rotation of the grating wheel, a first latching groove 4055 is provided on the outer surface of the first annular flange 4052. One end of a first paddle 409 can be inserted into the first latching groove 4055. The width of the first paddle 409 matches the inner diameter of the first semi-annular hole 407, so that the first paddle 409 can restrict axial movement of the grating wheel after being inserted into the first latching groove 4055. Preferably, the first latching groove 4055 is opposite the middle first groove 4054 among all the first grooves 4054, that is, the first latching groove 4055 is located in the middle of the upper half of the first annular flange 4052. In this way, the first paddle 409 can indicate the middlemost crack 4053. Of course, the first latching groove 4055 can also be located opposite any first groove 4054.

[0076] Preferably, the number of crack gears is marked on the outer wall of the main body 401, and the number of crack gears is marked on one side of the first semi-annular hole 407. The number of crack gears corresponds to the crack 4053 one-to-one, for example: the number of crack gears is 1, 2, and 3, wherein the size of the crack 4053 corresponding to the crack gear number 1 is: 1 mm × 1 mm, the size of the crack 4053 corresponding to the crack gear number 2 is 1 mm × 2 mm, and the size of the crack 4053 corresponding to the crack gear number 3 is 3 mm × 4 mm. The three sizes of cracks 4053 from 1 to 3 are evenly distributed on the upper half of the circular surface of the grating disk 4051, and the first slot 4055 is aligned with the crack 4053 corresponding to the gear number 2.

[0077] During installation, place the grating wheel from the front end of the main body 401 into the inner cavity of the main body 401, and install the first annular flange 4052 on the grating wheel on the first positioning ring 4011, rotate the grating wheel so that the first slot 4055 of the first annular flange 4052 is located at the center of the first semi-annular hole 407, and the first locking ball 4014 enters the first groove 4054 corresponding to the middle crack 4053, and then insert one end of the first paddle 409 into the first slot 4055, and the other end of the first paddle 409 is located outside the main body 401, completing the installation of the grating wheel. At this time, the first paddle 409 is aligned with the crack gear number 2, and light can pass through the crack 4053 corresponding to the crack gear number 2. When the size of the slits needs to be adjusted, the grating wheel can be rotated by turning the first paddle 409. When the grating wheel rotates, the first locking ball 4014 is pressed into the first blind hole, which does not block the rotation of the grating wheel. When the grating wheel rotates until another first groove 4054 (for example, the first groove 4054 corresponding to slit level number 1) is aligned with the first blind hole, the first locking ball 4014 enters the first groove 4054. At this time, the first locking ball 4014 locks the grating wheel, and the grating wheel no longer rotates. Light can pass through the slit 4053 corresponding to slit level number 1. In this way, the grating wheel can be rotated by turning the first paddle 409 to obtain the desired size of slits 4053. Light passing through different slits 4053 has different lengths and widths. During use, the user can be directly told which slit level number of slits 4053 to use, and the user can turn the first paddle 409 to align it with the corresponding slit level number.

[0078] like Figure 7As shown, the filtering mechanism 406 comprises a filter wheel, which includes a circular filter disc 4061 and a second annular flange 4062 located at the edge of the filter disc 4061 and perpendicularly connected to the filter disc 4061. The filter disc 4061 has multiple holes, with the centers of the holes distributed along a circle concentric with the filter disc 4061. Each hole houses a filter 4063 of a different color. Light passing through a filter 4063 of a different color becomes light of a different color. Preferably, five holes are evenly distributed on the circular surface of the upper half of the filter disc 4061, each housing a filter 4063 capable of transmitting red-free light, blue light, green light, red light, and white light. For example, light passing through the red-free filter 4063 becomes red-free light, while light passing through the blue filter 4063 becomes blue light, and so on. More filters 4063 of different colors can also be provided as needed.

[0079] The inner diameter of the second annular flange 4062 matches the outer diameter of the second positioning ring 4012. The second positioning ring 4012 can be inserted into the second annular flange 4062 and rotate relative to the second positioning ring 4012, thereby driving the entire filter wheel to rotate relative to the second positioning ring 4012. A plurality of second grooves 4064 are defined on the inner surface of the second annular flange 4062. The inner diameter of the second grooves 4064 matches the diameter of the second locking balls 4016, and the upper portions of the second locking balls 4016 can enter the second grooves 4064. The second grooves 4064 correspond one-to-one with the filter plates 4063. When viewed along the central axis of the filter wheel, the centerline of each second groove 4064 and the centerline of its corresponding filter plate 4061 lie on the same radius. A second latching groove 4065 is provided on the outer surface of the second annular flange 4062. One end of a second paddle 410 can be inserted into the second latching groove 4065. The width of the second paddle 410 matches the inner diameter of the second semi-annular hole 408, so that the second paddle 410, when inserted into the second latching groove 4065, can restrict the axial movement of the filter wheel. Preferably, the second latching groove 4065 is opposite the middle second groove 4064 among all the second grooves 4064, that is, the second latching groove 4065 is located in the middle of the upper half of the first annular flange 4052. In this way, the centermost filter wheel 4061 can be indicated by the second paddle 410. Of course, the second latching groove 4065 can also be located opposite any second groove 4064.

[0080] Preferably, the outer wall of the main body 401 is marked with a color name, and the color name is marked on one side of the second semi-annular hole 408. The color name corresponds to the filter disk 4061 one by one. For example, the color names are red-free, blue, green, red, and white (of course, numbers can also be used to correspond to colors, for example, 1 for red-free, 2 for blue, and so on), corresponding to red-free light, blue light, green light, red light, and white light, respectively. In this way, the five color filters 4063 of red-free, blue, green, red, and white are evenly distributed on the upper half of the circular surface of the filter disk 4061, and the second card slot 4065 is aligned with the green filter 4063 corresponding to green.

[0081] During installation, the filter wheel is placed into the inner cavity of the main body 401 from the rear end of the main body 401, and the second annular flange 4062 on the filter wheel is installed on the second positioning ring 4012, and the filter wheel is rotated so that the second slot 4065 of the second annular flange 4062 is located at the center of the second semi-annular hole 408. At this time, the second locking ball 4016 enters the second groove 4064 corresponding to the middle filter 4063, and then one end of the second paddle 410 is inserted into the second slot 4065, and the other end of the second paddle 410 is located outside the main body 401, completing the installation of the filter wheel. At this time, the second paddle 410 is aligned with the green filter disk 4061, and light can pass through the green filter disk 4061. To adjust the color, the filter wheel can be rotated by turning the second paddle 410. As the filter wheel rotates, the second locking ball 4016 is pressed into the second blind hole, preventing the filter wheel from rotating. When another second groove 4064 (e.g., the second groove 4064 corresponding to the blue color) of the filter wheel aligns with the second blind hole, the second locking ball 4016 enters the second groove 4064, locking the filter wheel. The filter wheel no longer rotates, allowing light to pass through the blue filter 4063. The filter wheel can then be rotated by turning the second paddle 410 to obtain the desired color of light. Light passing through different filters 4063 will have different colors. During use, the user can be directly told which color filter 4063 to use by turning the second paddle 410 to select the corresponding color name.

[0082] Light from light source 404 is positioned above the central axis of the housing, while the central axis of the reflective prism is positioned above the central axis of the housing. After adjusting the slit grating 405 and filter mechanism 406, light from light source 404 sequentially passes through filter 4063 of a selected color on filter disk 4061, slits 4053 of a selected size on grating disk 4051, and the reflective prism before exiting. This allows light from light source 404 to be tailored to specific observation or imaging needs, providing the necessary illumination for eye examinations and applicable to a variety of eye examinations.

[0083] The reflecting prism adopts an existing reflecting prism. After the light from the slit grating passes through the reflecting prism, on the one hand, the direction of the light can be changed (because the reflecting prism can accurately reflect the light to a new direction, which allows the light to be directed to a specific part of the eye), and on the other hand, the layout of the optical system can be made more compact (because by using a reflecting prism to change the light path, a more compact and flexible optical system can be designed, which is crucial for the portability and operability of the device). The angle of the reflecting prism is determined according to the required optical path design and imaging target, so that the light is emitted in a direction at a certain angle to the central axis of the shell, which is helpful for directing the light to a specific part of the eye rather than directly into the eye.

[0084] Reflective prisms are typically made of high-quality optical glass and wear-resistant and scratch-resistant materials to ensure maximum optical performance and device durability. Considering its application in eyewear, lightweight and durable materials such as BK7 glass or other highly transparent optical plastics may be selected.

[0085] In actual use, the adjustment process of the flexible rod 3 is as follows: first, determine the number of slit gears and the color of the filter required for illumination according to the shooting requirements, then turn the first paddle 409 and the second paddle 410 in sequence to rotate the grating disk 4051 to the corresponding slit gear position and the filter disk 4061 to the corresponding color name, and then adjust the flexible rod 3 to the appropriate position so that the light outlet hole 411 of the light-emitting component 4 is aligned with the user's eye. Because different test items may require light to illuminate different areas of the eye, the position of the flexible rod 3 is adjusted according to the actual test needs to ensure that the light is accurately irradiated to the required eye area. The device of the present invention can be used to perform comprehensive eye examinations, including but not limited to corneal, anterior chamber, pupil light reflex, iris and fundus retinal testing.

[0086] Furthermore, the glasses are equipped with a communication device comprising a microphone and a speaker. Two microphones are located on the frames outside the two lenses 102, respectively, to receive voice commands or feedback from the subject. For example, the subject can control the functions of the device by speaking commands such as "take a photo" or "record a video." The subject can also control the device to perform eye testing or training on the subject by speaking commands such as "test" or "train." The subject can also select and control the immersive media content displayed and played by the device by speaking commands such as "play," "pause," or "switch." After receiving the subject's voice commands or feedback, the microphones convert them into recognizable signals and transmit them to the control unit of the device. The control unit, using a voice recognition module, converts the signals into executable commands and performs the corresponding operations based on the commands. The control unit also uses the voice recognition module to convert the output voice information into playable sound, which is played back to the subject through the speaker of the device. This allows the subject to conveniently use and control the device through voice interaction. These techniques are well-established and will not be elaborated upon here. A pair of speakers are provided on the glasses for outputting sound information or prompts to the subject; the two speakers are respectively provided on the temples 103 and close to the free ends of the temples 103. After the user wears the glasses, the speakers are located in front of the ears and can transmit sound to the inner ear of the subject through bone conduction.

[0087] Furthermore, the glasses are also provided with a gyroscope for collecting head posture and motion data of the subject. The gyroscope can be provided on the inner side of the temple 103.

[0088] Furthermore, an accelerometer is provided on the glasses to detect the acceleration and movement of the subject's head. The accelerometer can be provided on the inner side of the temple 103, and the accelerometer can adopt an existing micro accelerometer.

[0089] Furthermore, the glasses are equipped with a magnetometer to detect the orientation and position of the subject's head. The magnetometer can be placed on the outside of the frame. By fusing data from the gyroscope with other sensors such as an accelerometer and a magnetometer, the angular velocity and angular displacement of the subject's head relative to the gravity reference plane or the device coordinate system can be calculated. The specific calculation method can use existing algorithms and is not within the scope of protection of this invention.

[0090] Furthermore, a wireless communication module is provided on the glasses for communicating with the subject's smartphone or other devices; the wireless communication module can be provided on the temple 103 .

[0091] Furthermore, a battery is provided on the glasses to provide power to the above components, and the battery can be provided on the temple 103 .

[0092] Furthermore, a controller is provided on the glasses to control the display or function of the glasses, which can adopt different forms and interaction methods, such as buttons, touch pads, gestures, voice, etc. The controller can be provided on the frame or the temples 103.

[0093] Microphones, speakers, gyroscopes, accelerometers, magnetometers, wireless communication modules, batteries, and controllers are all mature products and will not be discussed in detail here.

[0094] The eye detection device can be used to perform the following detection and training:

[0095] 1. Testing of wearing orthokeratology lenses:

[0096] Adjust the flexible rod 3 according to the requirements of corneal photography so that light is irradiated on the eye area to be photographed, and use the camera to take corneal photos. The corneal photos are input into the existing software through the controller for analysis, and then the corneal surface can be evaluated for abnormalities.

[0097] 2. Retinal disease health monitoring:

[0098] The flexible rod 3 is adjusted according to the requirements of retinal photography so that light is irradiated on the eye area to be photographed. The fundus photograph is taken by the camera, and the fundus photograph is input into the existing software through the controller for analysis, thereby obtaining the condition of retinal diseases, such as identifying macular degeneration or diabetic retinopathy.

[0099] 3. Neurological monitoring:

[0100] According to the requirements of the nervous system shooting, the flexible rod 3 is adjusted so that the light is irradiated on the eye area to be photographed. The eye is recorded using a camera (i.e., tracking eye movements and eye-through reactions). The image is then sent to the existing software for analysis through the controller, thereby obtaining pupil light reaction and eye movement tracking data.

[0101] 4. Cardiovascular system monitoring:

[0102] According to the requirements of cardiovascular system shooting, the flexible rod 3 is adjusted so that light is irradiated on the eye area to be photographed. The fundus vascular image is captured by the camera, and then the fundus vascular image is sent to the existing software for analysis through the controller. Then, the vascular changes can be obtained, and the health status of the vascular system can be evaluated based on the vascular changes.

[0103] 5. Visual training:

[0104] Training content is customized based on the user's vision condition and displayed through lens 102 to help the user train their eyes. For example, when a subject selects eye training, the training content is displayed on lens 102. The subject moves their head or eyes to align their gaze with the training content and confirms finding the target image in the training content through voice commands or touch operations. During this process, the camera captures real-time images or videos of the subject's eyes, which are then used to perform various eye tests.

[0105] 6. The present invention can be used to obtain pupillary light reflexes. Doctors can use this information to determine whether a subject has neurological diseases such as abnormal pupillary sensitivity or pupillary dysfunction. The specific method for determining this is beyond the scope of this invention. A database of images of normal subjects can be collected in advance to establish a normal range of variation. The device of the present invention can then be used to capture images of the patient. The subject's eye images and data can be transmitted to a smartphone or other device via a wireless communication module. By comparing the patient's images with those of normal subjects, the patient's specific condition can be determined. Alternatively, a beam of visible light can be emitted from light source 404 into the subject's eye, and an optical sensor can receive the reflected or scattered light from the subject's eye. The data collected by the optical sensor can be used to determine whether the subject has iris diseases such as iris pigmentation abnormalities, iritis, or iris neovascularization. Alternatively, light source 404 can be used to continuously emit a series of light beams of varying wavelengths and intensities into the subject's eye, and an optical sensor can record the subject's pupil size under light stimulation. Simultaneously, retinal photographs can be taken to record retinal nerve fiber layer and vascular morphological parameters. Using pupil size and retinal photographs to record fiber layer and morphological parameters is possible. This is achieved using various existing methods and is beyond the scope of this invention. VR, AR, and XR glasses have an open software platform. This platform is open source and relevant programs can be written based on existing algorithms to implement these judgments.

[0106] The utility model utilizes a light source module to illuminate the subject's eyes, and utilizes an acquisition module to acquire images and light signals from the subject's eyes. The images and light signals acquired by the utility model can be used to obtain eye biological indicators such as pupil diameter, pupil light reflex, iris texture, fundus retinal blood vessels, retinal neurovascular coupling reaction, and so on, thereby realizing the function of a "digital eye" capable of performing eye detection and training.

[0107] In addition, the present invention achieves precise tracking and positioning of the subject's head posture and movement, thereby achieving high-precision viewing angle control and scene switching; moreover, the present invention realizes data transmission and control with smartphones or other devices to achieve functions such as data synchronization, cloud storage, and remote diagnosis; in addition, the present invention can use an open source software platform to provide subjects with various eye gaze training, strabismus and amblyopia training and other applications, and the application platform can be infinitely expanded to help subjects improve their visual function and eye health.
