Description

Technical Field

[0001] This utility model relates to the field of eyewear technology, and more particularly to a virtual simulation eyewear that can be used for ciliary muscle detection. Background Technology

[0002] With the rapid development of virtual reality (VR) and augmented reality (AR) technologies, virtual reality glasses have been widely applied in various fields such as healthcare, education and training, and entertainment. In the healthcare field, especially in eye health monitoring, the ciliary muscle, as a key muscle regulating the curvature of the lens, is closely related to eye diseases such as myopia and eye strain. Studies have shown that the functional state of the ciliary muscle is not only affected by factors such as eye habits and ambient light, but also significantly correlated with local eye temperature. Temperature changes alter the metabolic rate, blood circulation, and muscle contraction ability of the ciliary muscle, thereby affecting its regulatory function. Precise monitoring and regulation of ciliary muscle temperature can provide important evidence for eye health assessment.

[0003] Virtual reality glasses, as wearable devices, are designed for prolonged close contact with the eyes, providing an ideal platform for real-time monitoring and intervention of ciliary muscle health. However, current virtual reality glasses generally lack dedicated functional modules for ciliary muscle health detection. On the one hand, the heat generated during operation may raise the local temperature of the eye, affecting the normal function of the ciliary muscle and interfering with the test results. On the other hand, they cannot actively regulate eye temperature, making it difficult to simulate the effects of different temperature environments on the ciliary muscle, thus limiting the comprehensive assessment of ciliary muscle function.

[0004] Therefore, this application proposes a virtual simulation glasses that can be used for ciliary muscle detection. Utility Model Content

[0005] To address the aforementioned issues, this invention provides a virtual simulation glasses device for ciliary muscle detection. This device enables real-time monitoring of ciliary muscle health, ensuring the patient's eye health during use and reducing potential risks.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A virtual simulation glasses for ciliary muscle detection includes a glasses body, wherein the glasses body is provided with a detection mechanism.

[0008] Preferably, the detection mechanism includes an infrared imaging module and a miniature probe, which are connected to the nose pad.

[0009] Preferably, the main body of the glasses is equipped with a warning mechanism, which includes an LED, a vibration motor, and electrode pads.

[0010] Preferably, the main body of the glasses is provided with a lens adjustment mechanism, which includes a front lens plate and a rear lens plate. The front lens plate is connected to the rear lens plate through a positioning shaft, and the positioning shaft is connected to a stencil. The positioning shaft is located on a sliding groove.

[0011] Preferably, the front mirror plate is provided with an annular rack, which meshes with a gear.

[0012] Preferably, the temples of the glasses body are provided with capacitive touch strips, which are communicatively connected to the temperature adjustment mechanism.

[0014] Preferably, the main body of the glasses is provided with a flow channel, and a piezoelectric pump is provided in the flow channel. The piezoelectric pump is communicatively connected to the capacitive touch strip.

[0015] Preferably, the temple is provided with a wireless charging mechanism, which includes a charging coil.

[0016] Preferably, the main body of the glasses is provided with a flexible conductive film, which is connected to the lens interlayer and electrically connected to the charging coil.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. This application uses a miniature probe and infrared imaging module installed on the nose pad to perform health detection on the ciliary muscle. The warning institution will provide vibration prompts to the patient based on the detection results, reminding the patient that they are currently in an overuse state. The low-frequency pulses released by the electrode patch will inhibit the over-excitation of the ciliary muscle.

[0019] The lens adjustment mechanism can increase the lens diameter to expand the field of vision and enhance immersion; it can also reduce the diameter to improve the clarity of the central area and reduce edge distortion, making it suitable for applications that require precise vision.

[0020] 2. By reducing the heat generated during the operation of the glasses through the temperature regulation structure, the risk of affecting the normal function of the ciliary muscle and interfering with the test results due to the local temperature rise of the eye is reduced. In addition, the temperature regulation structure can change the metabolic rate, blood circulation and muscle contraction ability of the ciliary muscle, thereby affecting its regulatory function.

[0030] Example 1

[0031] Please see Figures 1-6 As shown, this utility model relates to a virtual simulation glasses that can be used for ciliary muscle detection, including a glasses body 1, wherein a detection mechanism is provided on the side of the glasses body 1 near the lens, that is, near the nose pad;

[0032] Specifically, the detection mechanism includes an infrared imaging module 2 and a miniature probe 3.

[0033] Specifically, the micro probe 3 of this application adopts a laser speckle contrast imaging (LSCI) micro probe 3, wherein the micro probe 3 includes a VCSEL light source, a SPAD detector array and a synthetic aperture algorithm module. The micro probe 3 analyzes the micro-movement of the ciliary muscle by emitting low coherence laser (wavelength 785nm) and analyzing the changes in speckle pattern.

[0034] The testing agency and the warning agency are connected in communication. When the test result of the testing agency exceeds the threshold, the warning agency will issue a real-time warning to the user through the feedback of the testing agency. The user will be alerted to fatigue through the vibration motor 5 and LED 4.

[0035] Electrode patches 6 are provided on the main body 1 of the glasses. The electrode patches 6 are attached to the temples and infraorbital foramen around the eyes to release low-frequency pulses of 0.5-2mA and 10-50Hz to inhibit excessive excitation of the ciliary muscle.

[0036] A lens adjustment mechanism is provided at the lens, specifically including a front lens plate 7 and a rear lens plate 8. The front lens plate 7 is connected to the rear lens plate 8 through a positioning shaft 9. The positioning shaft 9 is connected to a shielding plate 10. The positioning shaft 9 is located on a sliding groove 11 and is slidably connected to the sliding groove 11. The sliding groove 11 is distributed on the front lens plate 7 and the rear lens plate 8.

[0037] Furthermore, both the front lens plate 7 and the rear lens plate 8 are provided with through holes for accommodating lenses, wherein the lenses are snapped into the through holes. The front lens plate 7 is provided with an annular rack 12, which is meshed with a gear 13. By rotating the gear 13, the blocking plate 10 is moved, thereby adjusting the field of view of the lens.

[0038] Specifically, a capacitive touch strip 14 is also provided on the main body 1 of the glasses. The capacitive touch strip 14 adopts a pressure-sensitive design, specifically including:

[0039] Position selection: The outer side of the temple 15 is the area where the user naturally holds the glasses, which is ergonomic and can be operated blindly without shifting the gaze.

[0040] Pressure-temperature mapping logic:

[0041] Short press: Switch temperature control mode (cooling / heating / off).

[0042] Long sliding: Stepless adjustment of temperature intensity (the higher the pressure value, the faster the temperature change rate).

[0043] Accidental touch prevention mechanism: The operation is triggered by a pressure threshold (e.g., >0.5N) to avoid accidental adjustment due to accidental touch.

[0044] Specifically, the capacitive touch strip 14 is communicatively connected to the temperature adjustment mechanism, which includes a thermoelectric cooling element, a temperature sensor, and a heat sink. A flow channel 16 is provided inside the glasses body 1, and a piezoelectric pump 17 is provided inside the flow channel 16. The piezoelectric pump 17 is communicatively connected to the capacitive touch strip 14.

[0045] The semiconductor cooling chip is integrated on both sides or top of the frame, and together with the flow channel 16, it forms a directional airflow, thereby forming a heat dissipation channel. The temperature sensor adopts an NTC thermistor or an infrared non-contact sensor to avoid physical contact interference.

[0046] Flexible electrothermal film: Embedded in the edge of the lens or the contact area of ​​the nose pad, it uses carbon nanotube / PTC material to achieve uniform heating and prevent the lens from fogging up.

[0047] The main body of the glasses 1 is provided with a flexible conductive film, wherein the flexible conductive film is embedded in the edge of the lens or the nose pad contact area, the flexible conductive film is connected to the lens interlayer, and a wireless charging mechanism is provided at the temple 15, the wireless charging mechanism includes a charging coil, wherein the flexible conductive film is electrically connected to the charging coil.

[0048] Specifically, the flexible conductive film uses carbon nanotubes / PTC materials to achieve uniform heating and prevent the lens from fogging up.

[0049] Example 2

[0050] Based on the above embodiment 1, the temperature sensors in the temperature regulation mechanism are distributed on the lens surface (monitoring environmental condensation), the core circuit area (chip temperature), and the facial contact area (epidermal temperature).

[0051] The piezoelectric pump 17 drives the cooling fluid to flow through the guide channel 16, absorb the heat of the lens body, and discharge it through the temple 15 or the heat sink of the lens frame. The piezoelectric pump 17 has a size of ≤10mm×5mm×2mm and is embedded in the temple 15 or the side of the lens frame. It is made of multilayer piezoelectric oscillator (PZT film thickness 10-50μm) using MEMS technology. The specific cooling liquid includes ethylene glycol aqueous solution and nanofluids.

[0052] Furthermore, the interior of the frame features a hollowed-out layer design to guide airflow around the core heating area, preventing direct airflow onto the user's face.

[0053] Furthermore, a humidity sensor is installed on the nose pad to detect the user's breathing or the humidity of the environment, and to trigger the temperature adjustment mechanism to prevent condensation on the lenses. The part of the nose pad that contacts the face uses thermally conductive silicone and a micro heating wire to maintain a physiologically comfortable temperature of 32-34℃ and prevent low-temperature burns or overheating erythema.

[0054] Furthermore, a protective shell 18 is provided on the side of the main body 1 near the lens, wherein the protective shell 18 is provided with several heat dissipation holes, and the temple 15 is filled with paraffin-based PCM to absorb instantaneous heat under high load, delay the active heat dissipation start frequency, and reduce noise.

[0055] Preferably, this application can wirelessly connect to a terminal to achieve remote control and monitoring, and dynamically adjust the heat dissipation / heating power based on sensor data, such as activating gradient heat dissipation when the ambient temperature is >25℃ and activating low-power heating when the ambient temperature is <10℃.

[0056] By recording usage time and environmental changes on the terminal, temperature requirements can be predicted (such as cooling down the device before high-load gaming).

[0057] The terminal has a user interface that allows users to manually switch power supply modes (energy saving / performance / custom) via physical buttons / touch area. For example, in sleep mode, the power saving mode is used during standby to maintain only basic sensing. When wearing is detected, the full functions are activated.

[0058] The terminal includes a mobile app, which allows users to remotely view temperature status, set thresholds, and receive high-temperature warnings.

[0059] Furthermore, a tungsten oxide (WO3) film is coated on the lens surface, and a voltage is applied to change the light transmittance (adjustable from 10% to 90%), simultaneously adjusting the amount of light entering the eye and the screen brightness.

[0060] A high-precision ambient light sensor (ALS) is embedded on the outer side of the virtual simulation glasses (upper edge / both sides of the frame), supporting dual-band detection of visible light (400-700nm) and infrared (850nm), avoiding interference from local light sources for a single sensor.

[0061] A wide-angle scattering filter is applied to the surface of the ambient light sensor to expand the range of light incident angles (>120°) and improve the accuracy of omnidirectional ambient light detection.

[0062] As a preferred option, an ultra-thin flexible electrode or strain sensor is attached to the skin around the eye to detect minute deformations caused by blinking or ciliary muscle movement. The strain sensor detection results are fed back to the warning mechanism and the detection mechanism, and adjustments are made in real time based on the feedback results.

[0063] Example 3

[0064] In this embodiment, the testing mechanism is connected to the terminal, and the terminal obtains the testing results from the testing mechanism. The testing mechanism further includes:

[0065] Tonometry: The tonometry is a non-contact tonometry. It uses the pressure generated by air pulses to flatten the cornea, and calculates intraocular pressure by measuring the time of corneal flattening and the pressure change.

[0066] A tonometer captures minute pressure changes caused by ciliary muscle activity by continuously recording intraocular pressure fluctuations. Abnormalities in the ciliary muscle (such as spasm or inflammation) can lead to disturbances in aqueous humor dynamics, which manifest as abnormal fluctuations in intraocular pressure, such as accommodative hypertension.

[0067] When using the eyes at close range, the ciliary muscle contracts and the lens thickens, which may momentarily increase intraocular pressure (physiological fluctuation of about 2-4 mmHg). Abnormal intraocular pressure fluctuations (such as sustained high pressure or violent oscillations) can be detected by an intraocular tonometer to indicate ciliary muscle dysfunction or early signs of glaucoma. The ciliary muscle over-tension can be indicated by detecting the accommodative intraocular pressure peak.

[0068] By capturing changes in pupil size and adjusting micro-tremors using a high frame rate camera (>200fps), and combining this with algorithms to infer the activity state of the ciliary muscle.

[0069] Optical coherence elastography (OCE): By illuminating the ciliary muscle region with low-coherence light, the phase change of the reflected light is analyzed to estimate the elastic modulus of the tissue (reflecting muscle tension).

[0070] High-frequency ultrasound sensor: It emits sound waves and uses the echoes to image the morphology of the ciliary muscle;

[0071] Miniaturized optical coherence tomography (OCT):

[0072] Optical signal transmission: The miniature swept frequency light source emits near-infrared light, which is split into reference light and sample light by an optical fiber splitter.

[0073] Tissue scanning: MEMS galvanometers control the sample light to scan the retina or cornea laterally, and the reflected signal carries tissue tomography information.

[0074] Interference and detection: The reflected light interferes with the reference light, and the interference spectrum is captured by an integrated detector.

[0075] Data processing: The frequency domain signal is converted into depth information through Fourier transform to generate a high-resolution tomographic image, which is then sent to the terminal.

[0076] The health status of the ciliary muscle is determined based on the tomographic images from the terminal.

[0077] Example 4

[0078] Based on the above embodiments, the working principle of this application can be derived as follows:

[0079] When wearing virtual simulation glasses, the micro probe 3 on the nose pad emits low coherence laser and analyzes the micro-movement of the ciliary muscle by speckle pattern changes to determine whether the ciliary muscle is abnormal, whether the user's ciliary muscle is overly tense or the eyes are fatigued, and the infrared imaging module 2 detects the blood flow and deformation of the ciliary muscle during contraction by changes in reflected light intensity to determine the health status of the ciliary muscle.

[0080] When the detection results of the miniature probe 3 and the infrared imaging module 2 exceed the threshold, the miniature probe 3 and the infrared imaging module 2 will feed back the detection results to the warning structure, activate the vibration motor 5 and the LED 4, so that the simulated glasses are in an alert state, reminding the patient that the use time is too long;

[0081] Simultaneously, the electrode patch 6, attached to the temples and infraorbital foramen around the eyes, is activated to release low-frequency pulses of 0.5-2mA and 10-50Hz, inhibiting excessive excitation of the ciliary muscle.

[0082] The temperature sensor detects the heat of the main body 1 of the simulated glasses. When the temperature is lower or higher than a preset value, the temperature adjustment mechanism is activated by touching the capacitive touch strip 14 on the outside of the temple 15. Specifically:

[0083] Short press: Switch temperature control mode (cooling / heating / off); Long slide: Stepless adjustment of temperature intensity (the higher the pressure value, the faster the temperature change rate);

[0084] By integrating semiconductor cooling chips on both sides or top of the frame, and using the flow channel 16 to form a directional airflow, a heat dissipation channel is formed. The piezoelectric pump 17 drives the cooling fluid to flow through the flow channel 16, absorbing the heat of the lens body and dissipating it through the temple 15 or the frame heat sink. The flexible conductive film embedded in the lens edge or nose pad contact area prevents the lens from fogging.

[0085] Based on the differences in the user's face shape, eye distance, and nose bridge height, the user rotates gear 13. Through the meshing connection between gear 13 and rack, the front lens plate 7 is rotated, causing the positioning shaft 9 connected to the shielding plate 10 to move on the slide groove 11, thereby realizing the adjustment of the lens's field of vision. By adjusting the size and diameter of the lens, it can better fit the face, reduce pressure, and enhance the seal to prevent light leakage.

[0086] Adjust the lens size flexibly according to the usage scenario. For example, increasing the lens diameter can expand the field of view and enhance the sense of immersion; while reducing the diameter may improve the clarity of the central area and reduce edge distortion, which is suitable for scenarios that require precise vision. That is, in scenarios that require high precision, reduce the diameter to improve the central resolution, and in entertainment scenarios, increase the diameter to enhance the sense of immersion.

[0087] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
