Description

Technical Field

[0001] The utility model belongs to the technical field of optical waveguide intelligent glasses, and in particular relates to a device for correcting and preventing amblyopia, strabismus and myopia. Background Art

[0002] With the increase of study pressure and the popularization of electronic products including mobile phones, more and more teenagers and other groups suffer from myopia. Apart from congenital genetic factors, the main cause of myopia is: long-term close-up use of the eyes, the ciliary muscles are in an overly tense state, which will increase the refractive power of the eyes over time. In addition, the eyeballs of teenagers have not yet fully developed, so they are more likely to develop myopia, amblyopia, and strabismus.

[0003] There are two main causes of amblyopia. The first is monocular strabismus during the visual development period. The second is anisometropia during the visual development period, such as a large difference in the refractive power of the two eyes, or high refractive errors, such as high hyperopia, myopia, astigmatism, etc., which may also cause amblyopia.

[0004] At present, the existing eye vision correction devices have shortcomings such as relatively single functions, inconvenient use, lack of fun, and poor prevention effect. In particular, there is no treatment device that can be worn continuously throughout the day in any occasion; for example: the device for preventing myopia cannot take into account the treatment of amblyopia, strabismus and other problems; some devices for treating amblyopia are too complicated and bulky, and are only suitable for professional treatment units and use with the cooperation of professionals, which is not convenient for treatment at home at any time; some devices for preventing myopia simply give voice prompts based on the time of eye use, or forcibly prevent eye use through a black screen, which lacks fun and cannot effectively relieve visual fatigue. Forcibly preventing eye use will also affect the safety of the wearer. Therefore, it is very necessary to provide a device that can take into account myopia prevention, amblyopia and strabismus correction. Summary of the invention

[0005] In response to the above problems, the utility model provides a device that is easy to wear and can take into account myopia prevention, amblyopia and strabismus correction. It can have the functions of myopia prevention, amblyopia and strabismus correction at the same time. The wearer can choose the corresponding mode according to needs, and it can be worn in any environment around the clock to meet the requirements of continuous treatment of glasses, so as to solve the problems raised in the above background technology.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Combined with Figure 1 , Attachment Figure 2 As shown, the utility model provides a device for correcting and preventing amblyopia, strabismus and myopia, which comprises glasses, the glasses are composed of a display carrier, a control device, a power supply device and a human-computer interaction device, the display carrier is connected to the control device, the control device is respectively connected to the power supply device and the human-computer interaction device, and the human-computer interaction device can control the display carrier to realize a preset display state through the control device;

[0031] The display carrier is installed in the frame 3 of the glasses, and is composed of a first lens and a second lens 2. The first lens is an optical waveguide lens 1, and the optical waveguide lens 1 is arranged on the surface of the second lens 2, and is used to display a preset display state while being able to fully transparently see through the real scene of the outside world;

[0032] The control device is composed of an optical machine, a main board and a sensor 5, wherein the optical machine is connected to the main board, and the main board is connected to the sensor 5;

[0033] The optical machine is arranged at the light incident side of the optical waveguide lens 1, that is, inside the lens frame 3, close to the connection between the lens frame 3 and the temples, and is used to send preset display content toward the optical waveguide lens 1;

[0034] The sensor 5 is arranged in the frame 3 structure of the glasses, and the main board is installed inside the temples hinged to the frame 3;

[0035] The power supply device and the human-machine interaction device are respectively installed inside the temples;

[0036] The power supply device is composed of a battery;

[0037] The human-computer interaction device is arranged on the outer surface of the temple and is used for external charging, status display, power on and off, and selection of display status.

[0038] The sensor 5 described in this embodiment includes a distance sensor that can detect distance, a time sensor that can detect time, a light intensity sensor that can detect light intensity, or one or more combinations of the above sensors;

[0039] The distance sensor includes a photoelectric distance detector or an infrared sensor or an accelerometer or a compass or a gyroscope or a satellite locator or a camera or one or more combinations of the above sensors;

[0040] The time sensor includes a timer;

[0041] The applications of the sensors described above are all prior art and will not be described in detail in this embodiment.

[0042] The installation position of the sensor 5 in this embodiment is as follows:

[0043] In the middle part of the frame 3 described in this embodiment, a sloped protrusion structure 4 is provided at the connection between the left lens and the right lens, and the sensor 5 is installed on the sloped protrusion structure 4. The sensor 5 is arranged at the sloped protrusion structure 4 with a certain angle, which is in line with the eye distance monitoring in actual usage scenarios, and is particularly suitable for usage scenarios when teenagers lower their heads or tilt their heads while studying.

[0044] The preset display states in this embodiment include the following three:

[0045] The first display state is: myopia prevention mode. In this display state, the sensor 5 can be a time sensor, which can be a timer, to detect the wearing time of the user. When the user wears the glasses for more than a preset time, the main board controls the optical machine, and the optical machine sends a preset display content toward the optical waveguide lens 1. The preset display content displayed by the optical waveguide lens 1 is: text or static image or dynamic image or video or a combination of the above contents.

[0046] The preset value in this embodiment can be personalized according to different user groups and application scenarios. For example, for a teenager learning scenario, the preset value can be set at 30 minutes; for a toddler reading scenario, the preset value can be set at 10 to 20 minutes; for an adult working at a desk, the preset value can be set at 60 minutes.

[0047] The preset display content can be set at a distance of 5 meters to 100 meters in front of the user's eyes, simulating the distant viewing function of both eyes, helping the user to relax and adjust the eye muscles, thereby reducing visual fatigue and further controlling the development of myopia.

[0048] The use of this embodiment can reduce visual fatigue and effectively prevent the further development of myopia. When the user stares at close objects for a long time, such as computer screens, mobile phones, etc., and the staring time exceeds a preset value, the optical waveguide lens of this embodiment will display preset display content, which will produce a visual effect of simulating looking into the distance, thereby helping the user relax the eye muscles and reduce eye fatigue.

[0049] Furthermore, the utility model can also prevent and control myopia by monitoring distance;

[0050] When the distance information detected by the sensor 5, which may be a photoelectric distance detector or an infrared sensor or an accelerometer or a compass or a gyroscope or a satellite locator or a camera or a combination of one or more of the above sensors, is less than a preset value, the mainboard controls the optical machine to send a preset display content toward the optical waveguide lens 1; when the distance information detected by the sensor 5 is greater than the preset value, the mainboard controls the optical machine to stop sending the preset display content to the optical waveguide lens 1, and the preset display content is used to prompt the user that the eye distance is too close. At this time, the user will be affected by the display content of the optical waveguide lens 1 and change the eye distance. If the user does not change the eye distance, the display content in the optical waveguide lens 1 will still exist, affecting the user's line of sight and forcing the user to change the eye distance.

[0051] The distance information described in this embodiment refers to the distance between the sensor 5 and the nearest object it can detect, which can be regarded as the eye distance in practical applications.

[0052] The preset value in this embodiment can be set individually according to different application scenarios. For example, for a teenager learning scenario, the preset value can be set between 20 cm and 30 cm.

[0053] For adults working at a desk, the preset value can be set at 40cm.

[0054] Furthermore, the utility model can also prevent and control myopia by monitoring light intensity;

[0055] The sensor 5 may be a light intensity sensor for detecting the light intensity of the user's environment. When the user wears the glasses and the light intensity is lower than the lowest preset value or higher than the highest preset value, the mainboard controls the optical machine, and the optical machine sends a preset display content toward the optical waveguide lens 1. The preset display content displayed by the optical waveguide lens 1 is: text or static image or dynamic image or video or a combination of the above contents.

[0056] When the sensor 5, the light intensity sensor, detects that the light intensity of the user wearing the glasses is between the lowest preset value and the highest preset value, the mainboard controls the optical machine to stop sending the preset display content to the optical waveguide lens 1;

[0057] In this embodiment, the minimum preset value can be set to 250 lumens, and the maximum preset value can be set to 500 lumens;

[0058] This embodiment adopts a myopia prevention and control method that integrates fully transparent lenses with optical waveguide display prompts. It will not cause any interference to the outside world in terms of sound or vibration. It can be worn in private spaces, in class, study, work, and life, which is safe and convenient.

[0059] The second display state is: a mode for correcting amblyopia. In this display state, the main board controls the optical machine, and the optical machine sends a preset display content toward the optical waveguide lens 1. The preset display content displayed by the optical waveguide lens 1 is: text or a static image or a dynamic image or a 3D image or a combination of the foregoing contents.

[0060] 3D image display training can help the amblyopic eye and the normal eye work better together, thereby improving visual perception and depth perception.

[0061] The use of the unilateral optical waveguide lens 1 can force the patient to use the amblyopic eye to observe, identify, track, and focus on the display content on the optical waveguide, thereby improving the coordination, contrast, and sensitivity of the eyes, and helping the amblyopic eye to develop and enhance better. Compared with covering the eyes, this method will not cause inconvenience to the user's daily life.

[0062] The third display state is: a strabismus correction mode. In this display state, the main board controls the optical machine, and the optical machine sends a preset display content toward the optical waveguide lens 1. The preset display content displayed by the optical waveguide lens 1 is: text or a static image or a dynamic image or a 3D image or a combination of the above contents;

[0063] The preset display content is displayed in the waveguide lens 1 in a manner that is offset from the horizontal direction within a range of 90 degrees to 0 degrees, and is always directly in front of the patient's pupil distance. Even if the patient tilts his head, the eyeball will not be offset, and the patient's eyeball is forced to always look straight ahead. This embodiment is not only suitable for corrective treatment of mild strabismus, but also for recovery training of patients with severe strabismus after surgery.

[0064] The optical waveguide lens 1 of this embodiment can be set on one side of the second lens 2 of the glasses, can be set on the left side of the second lens 2, can be set on the right side of the second lens 2, or can be set on both sides of the second lens 2, and can be set as needed according to the user's eye correction condition.

[0065] The content displayed in the optical waveguide lens 1 in this embodiment may be text, images, videos or 3D images, and the content of the text, images, videos or 3D images may be customized according to the usage mode or different user groups or usage scenarios;

[0066] For example, for the myopia prevention mode, the preset display content may be: a riddle, a joke, or a subject content that needs to be memorized, etc.;

[0067] The image content can be funny animated pictures, monochrome background pictures, or myopia prevention and control training pictures, etc.

[0068] For the amblyopia correction mode, the preset display content may be image materials or text materials suitable for different ages and different amblyopia degrees, according to the training requirements in terms of vision, space, color, etc.;

[0069] For the strabismus correction mode, the preset display content may be training materials with large color contrast and dynamic transformation in 3D space.

[0070] The diversity of preset display content and the personalized customization features in this embodiment increase the interest of the utility model, improve the wearer's interest in use, and can further enhance the correction and prevention effect.

[0071] The second lens 2 in this embodiment can be a plane lens, a myopia lens, an astigmatism lens or other known corrective lenses. The patient can configure the lens he needs according to the actual conditions of his eyes.

[0072] The temples of the present embodiment are also provided with charging interfaces for charging the glasses. The charging interfaces are simultaneously connected to the mainboard and can also be used as data interfaces to connect to the smart terminal.

[0073] The present embodiment also includes a smart terminal, and the glasses are connected to the smart terminal;

[0074] The intelligent terminal includes a smart phone, a tablet computer or a computer;

[0075] The smart terminal can be connected to the charging interface via a data cable, thereby connecting to the mainboard to import and delete display content;
