Abstract
Description
Technical Field
[0001] The present invention relates to the fields of ophthalmology, electronic optical imaging, microelectronic machinery, computer science and artificial intelligence, and in particular to a glasses system for acquiring myopia factors and a method for judging the failure of orthokeratology lenses. Background Art
[0002] With the development of electronic products, electronic products (such as mobile phones and tablet computers) have penetrated into people's daily lives, but watching the screen of electronic products for a long time will make users feel eye fatigue, dryness, blurred vision, dizziness and other problems. In addition, when looking at the screen of electronic products, it is difficult for users (especially children) to always maintain the correct posture and appropriate distance. Watching at a closer distance often brings users a better viewing experience (such as more shocking). Gradually, the continuous shortening of the distance will force the user's eye accommodation to increase, and even affect eye health. Whether these changes in modern environmental factors will aggravate users' myopia in the long run, there is still insufficient scientific evidence. However, the reality is that the current incidence of myopia is much higher than before, which makes people have to doubt the harmfulness of these electronic products to the eyes.
[0003] Clinical practice has found that the prevalence of myopia among students who are engaged in certain special courses may increase, and it can be speculated that myopia is related to the child’s daily learning content. After the doctor examines the child’s current myopia, he obtains the child’s daily activities through the parents’ description, and determines the main and secondary causes of the child’s myopia. The doctor then develops prevention, improvement or treatment plans based on the causes of myopia. However, parents do not stay with their children all day and always record the time of their children’s different sports, resulting in inaccurate activity data provided by parents. This method cannot objectively reflect the child’s true situation. Inaccurate eye use data and activity data will affect the doctor’s judgment of the factors that cause myopia, which also leads to a high failure rate in myopia treatment.
[0004] In order to prevent the rapid development of myopia, a kind of anti-myopia glasses accessory (or glasses) has gradually emerged on the market, which can determine the eye fatigue of the wearer (hereinafter referred to as the user) according to the eye usage, and promptly remind the user to relax the eyes and relieve fatigue. Or when the user uses an incorrect reading posture, the user is reminded to correct it in time.
[0005] The defects of this type of product are quite obvious, namely: judging whether the user is reading only by obtaining the distance of the object in front of the user, or judging the user's eye fatigue only by the light intensity. The impact of these parameters on the onset of myopia has not been fully recognized in the medical community, and people have a variety of reading habits. The above methods alone cannot accurately obtain the user's eye usage data. Summary of the invention
[0006] In view of this, the problem to be solved by the present invention is to provide an eyeglass system for acquiring myopia factors and a method for judging the failure of orthokeratology lenses, which can accurately judge whether the user is really reading and the stimulation of the eyes by the environment, and at the same time detect the user's vision changes based on the user's actual eye movement data and emotional change data, and promptly remind the user to make improvements. It is also convenient for doctors to accurately judge the user's myopia factors based on environmental parameters, activity parameters, electrophysiological parameters (EEG data), eye parameters and vision data.
[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0008] The invention discloses an eyeglass system for acquiring myopia factors and a method for judging the failure of orthokeratology lenses, comprising a sensor module, wherein the sensor module comprises an environmental spectrum sensor for accurately acquiring environmental parameters, a distance sensor, an angular momentum sensor, an acceleration sensor, an eye movement sensor, and an electroencephalogram sensor for acquiring data on changes in user emotions.
[0009] Furthermore, the system includes a power supply module, and the power supply module includes a first power supply battery installed on the glasses frame and a second power supply battery arranged in the glasses box;
[0010] The frame of the glasses is provided with a first charging contact point, and the glasses box is provided with a corresponding second charging contact point. A wireless charging solution can also be adopted.
[0011] Furthermore, the first power supply battery is a flexible battery.
[0012] Furthermore, the spectacle frame includes a spectacle frame and spectacle legs, and a power contact is provided at the connection between the spectacle frame and the spectacle legs, and power is supplied to the sensor module by opening the spectacle legs.
[0013] Furthermore, the sensor module data is obtained to generate environmental parameters, activity parameters, electrophysiological parameters (EEG data) and eye parameters, wherein the eye parameters include reading distance and reading posture data, and it is determined whether the reading distance and reading posture data reach a set warning threshold. If not, the reading distance and reading posture data are recorded; if yes, the user is reminded to improve and record the reading distance and reading posture data.
[0014] Furthermore, the reading distance data and reading posture data are distance data collected by two distance sensors combined with angular velocity sensor data, and the method for obtaining eye parameters includes: obtaining sensor module data and judging whether it is in a reading or observation state through an AI self-learning module, if not, not recording eye parameters;
[0015] If yes, the EEG sensor data is obtained and whether it meets the set threshold is determined. If no, the eye parameters are not recorded. If yes, feedback of being in the reading or observation state is given and the current sensor data is recorded to generate the eye parameters.
[0016] Furthermore, the activity parameter acquisition method includes: acquiring sensor module data, angular momentum and acceleration module data, determining the exercise type through an AI self-learning module, recording the user's daily exercise type and generating activity parameters.
[0017] Furthermore, the user's vision data is estimated by obtaining eye movement and EEG data, and the method for determining the vision data is as follows: obtaining eye movement data collected by an eye movement sensor and emotional change data collected by an EEG sensor, determining eye movement conditions (squinting or blinking) and emotional changes during the reading interval, estimating whether myopia is adequately corrected, and if not, reminding the user to wear or replace glasses with prescription;
[0018] Record environmental parameters, activity parameters, electrophysiological parameters (EEG data), eye parameters and vision data within a set time period so that doctors can determine the main factors leading to myopia and develop corresponding correction and treatment (including exercise or medication) plans.
[0019] Furthermore, the glasses with prescription are of a separate lens structure, and the lenses can be detachably mounted on the glasses frame.
[0020] Furthermore, the environmental parameters, activity parameters, eye parameters and vision data are collected for no less than three months, and six months is recommended.
[0021] The advantages and positive effects of the present invention are:
[0022] By installing an ambient spectrum sensor on the frame, we can obtain the light intensity data of red, green, blue, near-ultraviolet and near-infrared components in the environment, and accurately calculate the illumination, brightness and color temperature information of the ambient light based on the above data. The ambient light flicker information is calculated through an algorithm (based on exposure time and signal gain), and then accurately determine the stimulation of the ambient light to the eyes.
[0023] The frame is equipped with an EEG sensor, which determines the time when the user's brain is focused during reading, so as to accurately determine the actual reading time of the user. In addition, the electrophysiological parameters, eye parameters, activity parameters and environmental influencing factors are combined to comprehensively judge and find evidence with sufficient confidence that affects the rapid development of myopia in the human eye, filling the gap in evidence-based medicine in the field of myopia in optometry.
[0024] The first charging contact is installed on the glasses frame, and the second charging contact is set at the corresponding position in the glasses case. The glasses frame is charged in a contact manner, and there is no need to set a charging interface for connecting wires on the glasses frame, which ensures the aesthetics of the glasses and facilitates the charging of the glasses frame (the glasses frame will automatically start charging when it is put back into the glasses case). A wireless charging solution is also available.
[0025] Based on the user's eye movement data and EEG data when actually reading, the vision changes are estimated based on the eye movement and emotional changes. When the OK glasses become ineffective, the user is reminded to wear myopia glasses in time to improve the user's eye use. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0036] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a component centered. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0038] The present invention provides a glasses system for acquiring myopia factors and a method for judging the failure of orthokeratology lenses, such as Figure 3 As shown, the system includes a sensor module for acquiring data, a transmission module for wireless data transmission, a positioning module 5 for positioning, a mobile terminal for receiving data, and a data center for comprehensive data analysis and processing. The data acquired by the sensor module and the positioning module 5 are sent to the mobile terminal through the transmission module. The mobile terminal gives environmental parameters, activity parameters, electrophysiological parameters (EEG data) and eye parameters based on the received data. The mobile terminal transmits the above parameters to the data center for comprehensive analysis and processing for the doctor's reference and intervention plan. The data center sends the intervention plan given by the doctor to the mobile terminal, and the mobile terminal converts the intervention plan into rules and transmits them to the sensor through the wireless data transmission module as the reminder threshold judgment logic of each sensor.
[0039] like Figure 1 and Figure 2As shown, the sensor module includes an acceleration sensor 3, an angular momentum sensor, a distance sensor 2, an eye movement sensor, an environmental spectrum sensor 4 and an electroencephalogram sensor. The acceleration sensor 3 is used to obtain acceleration data in different directions of the glasses to sense the wearer's movement; the angular momentum sensor is used to obtain the tilt of the glasses and sense the wearer's head posture; the distance sensor 2 is used to obtain the distance between the front object and the glasses, the eye movement sensor is used to obtain the movement of the eyeball and eyelid, and the environmental spectrum sensor 4 is used to obtain the light intensity data of red light, green light, blue light, near ultraviolet light, and near infrared components, as well as the ambient light stroboscopic data, so as to accurately obtain the ambient light parameters of the eyes. The electroencephalogram sensor can be used to obtain the user's emotional change (such as attention) data, to obtain the user's actual eye parameters, to determine the user's actual reading situation and to predict the vision changes in combination with the eye movement sensor.
[0040] Preferably: because the glasses frame is a symmetrical structure, in order to ensure that the weight of the glasses frame (including the frame and two temples) is stable after the sensors are installed, the acceleration sensor 3, the angular momentum sensor, and the environmental spectrum sensor 4 are usually installed at the center beam of the frame to ensure the stability of the glasses frame structure.
[0041] The eye movement sensors are installed on the two ends of the frame and the inside of the two nose pads, and both face the eyeballs on the corresponding side. The brain electrodes 6 of the EEG sensor are respectively installed at the nose pads of the frame and the tails of the two temples (to ensure that the electrodes are in contact with the skin). The installation positions are symmetrically set to make the weight of the two frames consistent. The distance sensor 2 is respectively installed on the two ends of the frame and faces outward. According to the difference in distance between the two sides, the left and right head tilt can be calculated.
[0042] The wireless module can be a Bluetooth device or an NB-IoT device. The mobile terminal is usually a mobile phone with an APP installed. Users can view environmental parameters, activity parameters, and eye parameters in the APP. The data center is a cloud service that is used to analyze, process, and permanently store all user data, making it convenient for doctors to access remotely. After the doctor gives the relevant intervention plan, the data center is responsible for sending it to the user's APP, and then setting the prompt threshold judgment logic for each sensor.
[0043] The power supply module includes a first power supply battery 8 installed in the frame and a second power supply battery arranged in the glasses case. In order to ensure that the appearance and structure of the glasses frame are smooth and compact, and not affect the wearing and use of the glasses, the first power supply battery 8 is a flexible battery, and a contact charging first charging contact 1 (contact charging) is arranged on the glasses frame; a second charging contact is arranged in the glasses case correspondingly, and the glasses frame is placed in the glasses case. Since the position of the glasses case is fixed, the position of the glasses frame in contact with the glasses case is fixed, so the first power supply battery 8 is guaranteed to supply power normally. If economic conditions permit, users can also choose wireless charging to charge the first power supply battery 8.
[0044] For example, the ends of the suspended ends of the temples and the lower edge of the frame are also provided with second charging contacts at corresponding positions in the glasses case. When the glasses frame is placed in the glasses case, the first charging contact 1 contacts the second charging contact, and the first power supply battery 8 is automatically charged. The user only needs to charge the glasses case, which is convenient for charging without increasing the size of the frame, thereby ensuring the aesthetics and practicality of the frame. Preferably, the second power supply battery is charged by wired charging to ensure charging efficiency.
[0045] Preferably, the size of the first power supply battery 8 is 4x4x50MM, and the capacity is not less than 30mAh. Because the overall volume of the frame is relatively small, if a charging connector is installed, the overall volume of the frame will increase, affecting the appearance structure and smoothness of the frame. There are Micro USB, Type-C and Apple's Lightning interfaces on the market. The Micro USB interface is flat and can only be inserted on one side. The Type-C interface is characterized by being insertable on both sides and has a hollow oval shape. Apple's Lightning interface also supports both sides. The shape of the phone is a solid oval. Because the types and sizes of charging connectors on the market are fixed, they occupy a large amount of space inside the frame, increasing the volume and affecting the integration space of other sensors.
[0046] In order to prevent the first power supply battery 8 from still supplying power to the sensor on the eyeglass frame when the user is not wearing the eyeglass frame, a power supply contact 7 is provided at the connection between the temple and the frame. When the temple is opened, the first power supply battery 8 is connected to the sensor, and the sensor works normally; when the temple is folded, the power supply is automatically disconnected. By obtaining the working time of the sensor, the length and time period of the user wearing the glasses every day can be recorded.
[0047] Furthermore: the user's living habits and office habits can be determined based on the time period when the user wears glasses and the eye usage during this period, so that the diagnosis end can formulate corresponding evaluation suggestions based on the user's glasses wearing habits.
[0048] For example, if a user only wears glasses during the day and is always reading, it can be determined that the user works or studies during the day, but not at night, and wears glasses only for work or study. If a user wears glasses all day, and reads, exercises, and participates in indoor and outdoor activities after wearing glasses, it indicates that the user is highly dependent on glasses. The diagnosis end gives evaluation suggestions based on the user's actual myopia situation to reduce the probability of rapid development of myopia in the user.
[0049] The positioning module 5 is used to obtain the user's geographical location, because different geographical locations may have different effects on myopia. The air humidity and light intensity in the north and south are different, and the effects on myopia are not exactly the same. The evaluation end can obtain the user's location information and adjust the evaluation suggestions and warning thresholds according to different geographical locations. When the glasses are used by children, because children do not carry mobile phones (cannot be located by mobile phones), a positioning chip can be added to the frame. Every time the child goes out to play (the glasses send location information to the parent's mobile phone via Bluetooth or NB-IoT devices (NB-IoT devices can view the location in real time)), parents can check the child's activity path (this function can be turned on selectively).
[0050] Similarly, in order to ensure the symmetry of the weight of the frame, the positioning module 5 and the wireless module are arranged at the middle beam of the frame.
[0051] Users do not go to the hospital for eye examinations very frequently, but their activities and myopia conditions are constantly changing (such as whether myopia is progressing or not), and their eye environment (seasonal changes, home, campus, and outdoors, etc.) and eye habits (lifestyle habits) are changing. Doctors can also give corresponding adjustment suggestions remotely and in a timely manner to reduce the probability of rapid development of myopia in users.
[0052] The system is also equipped with an evaluation terminal, which can also be an online doctor. The mobile terminal uploads the user's eye parameters to the data center, and the evaluation terminal can obtain them. The evaluation terminal determines whether myopia has worsened or whether new living habits have affected myopia based on the eye parameters, and adjusts the evaluation suggestions and warning thresholds on the APP application based on the above factors.
[0053] The evaluation suggestions include suggestions on eye habits, exercise duration, diet, and even medication. The warning threshold is the threshold of bad eye parameters (activity parameter threshold of new living habits) or the threshold of eye time in harmful light environments. Users adjust their living and eating habits accordingly based on the evaluation suggestions to avoid the rapid development of myopia.
[0054] When users go to the hospital for an eye examination, the doctor will develop a reasonable correction or treatment plan based on the actual examination results of myopia, and appropriately modify the evaluation recommendations and warning thresholds on the APP.
[0055] Correction solutions include: doctors select and wear appropriate frame glasses based on the actual eye examination results (the eyeglass system of the present invention is also a high-precision frame glasses). Or select appropriate OK lenses to achieve the purpose of slowing down the progression of myopia. Usually, OK lenses are worn at night, and vision is normal during the day, but when OK lenses fail, frame glasses are used. Or low-concentration atropine is used to slow down the progression of myopia. Or a combination of frame glasses and low-concentration atropine or a combination of OK lenses and low-concentration atropine.
[0056] Evaluation suggestions: reasonable reading time, reading distance, reading posture, ambient lighting, diet and lifestyle suggestions for users. Warning thresholds: reading distance threshold, reading posture threshold, reading time threshold, ambient light illumination threshold, ambient light brightness threshold, ambient light spectrum component threshold, ambient light color temperature threshold, ambient light flicker threshold, and activity duration threshold.
[0057] A method for preventing myopia, improving or treating the rapid development of myopia, such as Figure 4 As shown, the sensor module and positioning module 5 data are obtained to determine the user's environmental parameters, activity parameters, electrophysiological parameters (electroencephalogram data) and eye parameters. Environmental parameters include: ambient light illumination, brightness, color temperature, spectral components and ambient light strobe. Figure 5 As shown, the acquisition method is: obtain data from the ambient spectral sensor 4, which includes light intensity data of red light, green light, blue light, near ultraviolet light, and near infrared components (spectral span 360nm~1060nm), and calculate the illumination, brightness, spectral components, color temperature, and ambient light flicker of the ambient light for the eyes based on the above component data.
[0058] Activity parameters include: running, walking, jumping, football, basketball, badminton, table tennis, reading paper books, looking at display screens, playing piano, playing violin, etc.
[0059] like Figure 6 As shown, the method for obtaining activity parameters: the data obtained by the positioning module 5 can also be used in conjunction with the data of the sensor module. The AI self-learning module obtains the data of the positioning module 5 and generates the user's movement trajectory data. The user's activity area is constructed according to the user's stay time, exercise and reading conditions at different times and locations. Different areas correspond to different activity conditions (such as indoor areas, outdoor areas)
[0060] The AI self-learning module determines the user's current activity (whether he is exercising) based on the sensor module data, and determines the user's location based on the user's location information, and determines whether the area is an activity area. If yes, the activity parameters of the user's current exercise are recorded; otherwise, no data is recorded.
[0061] Using the same method, it is possible to determine whether the user is eating, running, playing the piano, etc., and record and generate corresponding activity parameters so that doctors can determine the user's myopia factors based on the user's living habits.
[0062] like Figure 7As shown, the method for judging the eye parameters is as follows: the AI self-learning module obtains the data of distance sensor 2, angular momentum sensor and eye movement sensor to judge whether the user is in a reading state. If not, feedback information is given and the eye parameters are not recorded. If yes, the EEG sensor data is obtained and judged whether it meets the set threshold (determine whether the user is reading). If yes, feedback of being in a reading state is given and the current sensor data is recorded to generate eye parameters and electrophysiological parameters (EEG data), and the reading time is recorded to obtain the daily reading time.
[0063] Since people have limited attention span, their brains will be idle for a period of time during the reading process. In order to more accurately obtain the user's daily reading time, the user's emotional changes collected by the EEG sensor are used to analyze the concentration level, and the time is further corrected to generate the actual reading time.
[0064] Correction solutions include the use of frame glasses, contact lenses (such as orthokeratology lenses) or therapeutic drugs (such as low-concentration atropine). When users use orthokeratology lenses, they can always monitor changes in vision during the day.
[0065] Because the rate of corneal shape change varies from user to user, the time of failure of orthokeratology lenses to correct vision is uncertain (the cornea will slowly return to its original state, causing the correction to fail). Correction failure occurs slowly, not suddenly, and doctors cannot make an accurate judgment. When the correction fails, users cannot wear spare myopia glasses in time, which affects the user's eye use and further affects work or study.
[0066] The method for determining whether the user's myopia is sufficiently corrected includes: obtaining eye movement data collected by an eye movement sensor and emotional change data collected by an EEG sensor, determining eye movement conditions (squinting or blinking) and emotional changes during the reading interval, estimating whether the myopia is sufficiently corrected, and if so, reminding the user to wear or replace glasses (spare myopia glasses), and recording the time when vision loss occurs.
[0067] Preferably, the lens on the frame is detachable. After the orthokeratology lens correction fails, the user can wear a lens with a degree to avoid affecting the user's normal activities.
[0068] When the user goes to the hospital to check his vision, the doctor will adjust the degree of the user's spare myopia glasses based on the user's actual vision and the data on the time when vision will expire. By accurately obtaining the changes in the user's vision after wearing orthokeratology lenses (expiration time), the doctor can configure appropriate spare myopia glasses (appropriate degree to avoid overcorrection and worsening myopia) and the user can wear the spare myopia glasses in time, thereby reducing the probability of rapid development of myopia in the user.
[0069] Because the rate of myopia progression is not fixed, doctors can quickly and objectively analyze the factors that cause myopia for different users based on the recorded eye environment parameters, activity parameters, electrophysiological parameters (EEG data), eye usage, and myopia progression, and formulate corresponding correction or treatment plans.
[0070] Preferably: the collection time of eye environment parameters, activity parameters, electrophysiological parameters (EEG data), and eye usage conditions is no less than three months, and six months is recommended.
[0071] Furthermore, when reading, users will not maintain a fixed posture for a long time, but will change postures from time to time. However, sometimes the myopia problem will be further aggravated due to the incorrect reading posture for a long time. Therefore, a vibrator or buzzer is added to the frame. When the user has an incorrect reading posture, the buzzer or vibrator will remind the user. The buzzer or vibrator is usually installed on the two sides of the glasses to ensure the stability of the glasses' gravity and prevent the glasses from falling off during vibration. It can also provide prompts for different situations by changing left and right.
[0072] After determining that the user is in a reading state, the distance sensor 2, angular momentum sensor and auxiliary eye movement sensor are used to determine whether the user has a bad reading posture and record the number of times. After determining that the user is in a reading state, the distance sensor 2, angular momentum sensor and eye movement sensor data are used to determine whether the user has amblyopia or strabismus.
[0073] The distinction between indoor and outdoor is usually made by judging whether the user is in natural light or lighting. The method for obtaining the indoor and outdoor residence time is as follows: the data collected by the environmental spectrum sensor 4 is obtained, and the data includes the light intensity data of red light, green light, blue light, near ultraviolet light, and near infrared components (spectral span 360nm~1060nm), and the ambient light illumination, brightness, color temperature and flicker are calculated based on the above component data. Because the color temperature and illumination of different lighting equipment are different, the user is judged whether he is indoors or outdoors by judging the range of illumination, brightness, color temperature and flicker (there is generally no flicker outdoors).
[0074] If the user must stay indoors for a long time, the different components of ambient light data are obtained, and the degree of damage to the user's eyes caused by ambient light is calculated based on the range of illuminance, brightness, color temperature and flicker, so as to remind the user to avoid it in time and reduce the probability of rapid development of myopia. When it is detected that the user is working in a high-illuminance and high-brightness environment (according to individual differences, a doctor must assist in setting the threshold), the user is reminded to adjust the brightness, illuminance, color temperature and flicker of the ambient light in time.
[0075] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of this patent.
