Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to an infrared wearing device for eye therapy. Background Art

[0002] Infrared therapy is a mature eye therapy method. The basic principle is: infrared can penetrate eye tissue, produce a warming effect, promote blood circulation, relieve eye pain, and improve blood supply; infrared can stimulate cell metabolism, accelerate the repair and regeneration of damaged cells, and facilitate the recovery of fundus diseases; through the soothing effect of infrared, it can relax eye muscles, relieve eye fatigue and tension, and reduce intraocular pressure. Therefore, infrared therapy has many applications in fundus diseases. For example, in the application of auxiliary therapy for macular degeneration, infrared can promote blood circulation in the macular area, slow down the progression of macular degeneration, and help protect the retina; in the application of retinal disease rehabilitation, infrared can improve the oxygen supply of the retina, promote retinal cell repair, and accelerate the recovery process; in the application of glaucoma treatment, infrared therapy can effectively reduce intraocular pressure, help relieve symptoms of glaucoma patients, and reduce pain and visual impairment.

[0003] In order to promote infrared therapy and make it not limited to professional medical equipment, wearable products with infrared therapy functions have appeared on the market, combining infrared emission sources with daily necessities to meet the needs of users at home. For example, the irradiation device disclosed in patent application number CN201680070809.9 discloses a glasses-type device, in which the light source is arranged at the junction of the glasses leg and the glasses frame, and the light of the light source is directed toward the wearer's eyeball. An ear-hanging device is also disclosed, in which the extended end of the ear-hanging bracket is placed in front of the eyeball, and a light source is arranged at the end, and the light is directed toward the eyeball.

[0004] The above two products have their own advantages and disadvantages. The glasses-type irradiation device hides the light source on both sides of the eyeball, and will not block the wearer's front vision during use. However, the light source of this style of product is offset, and the infrared light has a small coverage range for the eyeball. The ear-hanging type irradiation device places the light source in front of the eyeball, so that the coverage range of the emitted light for the eyeball is increased, but the light source of this style of product will block part of the wearer's field of vision.

[0005] The above problems are worth solving. Utility Model Content

[0006] In order to overcome the problem that the existing infrared eye therapy wearable device cannot achieve a large coverage of the eyeball by the infrared light source of the device without blocking the wearer's front field of vision, the utility model provides an infrared wearable device for eye therapy.

[0007] The technical solution of the utility model is as follows:

[0033] like Figures 1 to 4 As shown, an infrared wearable device for eye therapy includes a frame, a nose pad 2 and temples. The inner side of the temple near the frame is provided with an infrared light emitting source 1. The infrared light emitting source 1 can emit infrared light with a wavelength of 800 nanometers to 820 nanometers. The infrared light in this band can be used to improve eye fatigue caused by long-term use of the eyes, and has a relieving and repairing effect on the condition of yellow spots in the eyes. Figure 3 At point A and point B, two infrared light emitting sources 1 on the left and right temples emit infrared light from outside to inside, from A to C, or from B to D. In this embodiment, the infrared light emitting source 1 is an LED lamp bead, and its optical power is less than 0.39 milliwatts, which ensures safety while providing effective infrared light heating effect.

[0034] In order to increase the coverage of the infrared light to the eyes, the nose pad 2 is provided with a first reflective surface 21 for reflecting infrared light. Specifically, the side of the nose pad 2 facing the temple is coated with a reflective layer, which may be a silver layer, an aluminum layer or a gold layer. The nose pad 2 and the infrared light emitting source 1 are located at the same level. The infrared light emitted by the infrared light emitting source 1 can hit the first reflective surface 21 of the nose pad 2. The nose pad 2 has a certain curvature, so that the first reflective surface 21 becomes a concave mirror. The infrared light is diffused after being reflected by the first reflective surface 21, thereby increasing the coverage of the infrared light. Figure 3 In the figure, the infrared light is emitted from point A and reflected at point C. The propagation path of the infrared light in front of the eye increases, covering most of the area, thereby improving the coverage of the eye by the infrared light. Figure 4 , the figure magnifies the light propagation path of the AC part. Similarly, there is also infrared light going back and forth between point B and point D in the figure, and there is a certain light diffusion effect.

[0035] In the present invention, not only the first reflection surface 21 is provided, but also the inner surface of the lens is coated with an aluminum oxide film to form a second reflection surface 3 for reflecting infrared light. Aluminum oxide (Al2O3) is an inorganic material with a high refractive index, which can effectively reflect light of a specific wavelength. The aluminum oxide film is coated on the inner surface of the lens, and its main function is to reflect infrared light, especially infrared light in the 800-820 nanometer band. The aluminum oxide film has a high transmittance to visible light, achieving high reflectivity to infrared light and high transmittance to visible light. This means that, despite the presence of an aluminum oxide film on the surface of the lens, the lens remains highly transparent to the wearer, and does not affect their observation of the outside world; at the same time, when the infrared light emitting source 1 is working, the aluminum oxide film can effectively reflect infrared light to the eyeball, thereby increasing the coverage of the eye.

[0036] In the present invention, for the visible light band of 400 nanometers to 700 nanometers, the optical film thickness (i.e., the product of physical thickness and refractive index) of the aluminum oxide film is designed to be an odd multiple of one quarter of the wavelength of light, and the interference effect of visible light inside the aluminum oxide film will lead to destructive interference, thereby reducing reflection and increasing transmission. In a specific embodiment, the physical thickness of the aluminum oxide film ranges from 50 nanometers to 200 nanometers.

[0037] like Figure 2 As shown, by adopting the above scheme, the infrared light emitting source 1 emits scattered infrared light with a light output angle of not less than 120°. The infrared light that is laterally divergent, the part that is laterally directed inward is directed toward the eye, and the part that is laterally directed outward is directed toward the inner surface of the lens, and then is reflected to the eye by the second reflection surface 3. Therefore, the second reflection surface 3 can utilize the light directed outward toward the lens to increase the utilization rate of the infrared light. The infrared light that is longitudinally divergent from the infrared light emitting source 1 has a certain coverage area on the mirror surface. The light that reaches the first reflection surface 21 is reflected again and passes in front of the mirror surface again. The two round-trip diffusion lights make the infrared light fully cover the area in front of the eye.

[0038] It can be seen that the utility model increases the propagation path of the infrared light in front of the eye by arranging the first reflective surface 21 at the position of the nose pad 2, and the coverage area of ​​the infrared light in front of the eye is denser, and the coverage area is increased; the utility model also arranges the second reflective surface 3 on the mirror surface, which increases the infrared light irradiated from the mirror surface to the eye direction, and the infrared light received by the eye is denser, further improving the coverage effect of the infrared light on the eye area; and the lens has a high transmittance to visible light, and the lens still maintains a high degree of transparency, which does not affect the wearer's observation of the outside world.

[0039] In a preferred embodiment, a curved reflector 5 is provided on the top of the nose pad 2, and the concave surface of the curved reflector 5 is used to reflect the infrared light of the infrared light emitting source 1 on the same side. For example, a first curved reflector is provided above the nose pad 2 at point C, and the first curved reflector reflects part of the infrared light emitted from the infrared light emitting source 1 at point A; similarly, a second curved reflector is provided above the nose pad 2 at point D, and the second curved reflector reflects part of the infrared light emitted from the infrared light emitting source 1 at point B. It can be seen that the function of the curved reflector 5 is to extend the reflective surface of the nose pad 2, reflect part of the light emitted from the infrared light emitting source 1 above, and further improve the utilization rate of the infrared light.

[0040] In an optional embodiment, the arc reflector 5 is made of aluminum, silver, or gold, and its concave arc surface is polished to remove tiny surface defects and irregularities, reduce light scattering and absorption, and ensure efficient reflection of infrared light.

[0041] In an optional embodiment, the curved reflector 5 uses plastic as a substrate. Plastic has the advantages of low cost, light weight, and easy processing and molding. However, the reflectivity of plastic itself is not as good as that of metal. Therefore, it is necessary to perform metal plating on the surface of the plastic substrate, such as plating with a silver layer, an aluminum layer, or a gold layer. The silver-plated layer usually has the highest reflectivity, the aluminum-plated layer has good corrosion resistance and better cost-effectiveness, and the gold-plated layer has excellent chemical stability to maintain long-term reflective performance.

[0042] In an optional embodiment, the material of the arc reflector 5 is glass, and the concave surface of the arc reflector 5 is coated with a metal oxide coating, and the metal oxide coating is an aluminum oxide coating, a magnesium oxide coating, a zirconium oxide coating or a nickel oxide coating.

[0043] In a preferred embodiment, the first reflective surface 21 of the nose pad 2 is inclined to the mirror surface. Specifically, the first reflective surface 21 is inclined toward the direction of the eyes instead of facing the infrared light emitting source 1, so that the light reflected by the first reflective surface 21 is biased toward the eye side, ensuring that the infrared light can be effectively guided to the eye area of ​​the wearer, thereby improving energy utilization efficiency.

[0044] Embodiment 2

[0045] An infrared wearable device for eye therapy, the rest of the structure is the same as the first embodiment, the difference is that: the temple is embedded with a working mainboard, the working mainboard is provided with the infrared light emitting source 1, the microcontroller and the inductive sensor 4, and the infrared light emitting source 1 and the inductive sensor 4 are both electrically connected to the microcontroller. The inductive sensor 4 is used to sense the face of a person and transmit the signal to the microcontroller, and the microcontroller automatically turns on the infrared light emitting source 1 according to the signal. When the user wears the device, the inductive sensor 4 senses the side of the user's face and sends a signal to the microcontroller, which responds to the signal and starts the infrared light emitting source 1. The device of this embodiment has a high degree of automation, simplifies the use steps, and provides convenience for the user's operation.

[0046] In this embodiment, the working mainboard is also provided with a gravity sensor, and the gravity sensor is connected to the microcontroller. The gravity sensor continuously monitors the direction and acceleration of the glasses relative to the earth's gravity. When the user wears the glasses, the acceleration detected by the gravity sensor is mainly composed of gravity and the user's head movement. When the glasses are placed on the desktop, the acceleration detected by the gravity sensor will be significantly reduced, because the glasses are in a stationary state at this time, and there is no acceleration generated by the head movement. Based on this principle, by analyzing the data of the gravity sensor, it can be determined whether the glasses are in a horizontal position. Once it is detected that the glasses are placed on the desktop, the built-in microcontroller triggers a power-off command, thereby realizing automatic shutdown when the glasses are placed on the desktop.

[0047] In this embodiment, the microcontroller has a built-in timer. After the infrared light emitting source 1 is started, the timer starts counting according to the preset time. When the preset time is over, the microcontroller will automatically turn off the infrared light emitting source to end the physical therapy. In addition, the user can preset the time, such as 5 minutes, 10 minutes, etc., through the supporting mobile application or the physical button set on the wearable device.

[0048] In an optional embodiment, the work board is integrated with a Bluetooth communication module, and the infrared wearable device can be connected to a Bluetooth headset or other electronic devices with Bluetooth communication function through the Bluetooth communication module to achieve Bluetooth connection between the infrared wearable device and other electronic devices.

[0049] In the utility model, the infrared wearing device is designed in the shape of glasses, and the lenses of the glasses can be plain lenses, myopia lenses or hyperopia lenses according to the needs of users.

[0050] Embodiment 3

[0051] like Figure 5As shown, an infrared wearable device for eye therapy, the rest of the structure is the same as that of the first embodiment, except that: the upper edge and the lower edge of the frame are provided with a second emission source 6, the second emission source 6 is used to emit infrared light of 800 nanometers to 820 nanometers. The light emitting angle of the second emission source 6 is 120 degrees.

[0052] In this embodiment, the second emission source 6 is provided to increase the infrared light density in the area above and below the lens, thereby further improving the coverage of the infrared light in the eye area. It should be noted that the second emission source 6 is provided inside the frame, and the position area of ​​the second emission source is indicated by rectangular inclined hatching in the figure; the concentric circles at the lens indicate the coverage effect of the infrared light, which is not a specific structure visible in the actual product.

[0053] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
