Description

Technical Field

[0001] The present invention relates to a portable diopter examination instrument based on DeepSeek, which is a portable artificial intelligence technology (hereinafter referred to as AI) diopter examination device that combines the DeepSeek large data model, the diopter examination instrument lens, a tablet computer, and an electric pan-tilt. It can very conveniently provide an accurate digital refractive degree detection solution and an excellent user visual correction examination experience. Background Art

[0002] The refractive system of the human eye includes the cornea, aqueous humor, lens, and vitreous humor. Their common function is to accurately focus parallel light rays on the retina. The diopter (D) exactly describes the refractive power of the eye, and its magnitude is the reciprocal of the lens focal length (f), that is, D = 1 / f. When the diopter D = 0, it is called emmetropia, just like a camera. When the degree of the lens matches the length of the camera body, the outside scenery can pass through the lens and be focused to form a clear image on the film. Similarly, if the parallel light rays pass through the refractive system of the human eye and the focus falls in front of the retina of the naked eye, it is called myopia; if the parallel light rays pass through the refractive system of the human eye and the focus falls behind the retina of the naked eye, it is called hyperopia; if the parallel light rays pass through the refractive system of the human eye and cause the light rays not to fall on the retina, it is called astigmatism; whether it is myopia, hyperopia, amblyopia, strabismus, or astigmatism, they all belong to refractive errors, and the degrees of refractive errors are measured by diopters, which is why many people wear glasses. Because, under the current medical technology conditions, refractive errors still cannot be cured and can only be corrected by wearing glasses. The so-called refractive error is actually a problem caused by an abnormal refractive state of the eye. For example, axial myopia is caused by the elongation of the eye axis of the eye. Of course, it cannot be changed by relaxing the eye muscles, nor can the length of the internal eye axis be improved by eating pig liver or spinach.

[0003] Therefore, the refractive error caused by the malfunction of the refractive system of the human eye can only be corrected by a diopter compensation scheme. Specifically, the purpose of diopter compensation is to adjust the optical path to adapt to the dynamic changes of the refractive state of the human eye, so as to achieve accurate correction between the focal length and aberration of the human eye and ensure the accuracy and clarity of imaging. This is also the reason why many people find that their eyesight is poor and the optician's business is booming.

[0004] Currently, the internationally common refractive criterion is based on feature extraction and data classification and recognition. This is also the refractive criterion followed by the DeepSeek large model. Because DeepSeek also makes predictions based on a large amount of data learning and analysis of cases, and discovers potential patterns in the data, so as to deeply complete the associated reasoning and diagnosis tasks: 1. Myopia (hyperopia) degree: Mild: 0 - 300 degrees, Moderate: 300 - 600 degrees, High: above 600 degrees 2. Astigmatism degree and axis position: Mild: 0 - 100 degrees; Moderate: 100 - 200 degrees; Severe: 200 - 300 degrees; Ultra - high astigmatism: above 300 degrees; 3. Presbyopia degree: First, predict according to age as follows: Among them, the criteria according to age are as follows: 40 - 50 years old: Presbyopia 100 degrees; 50 - 60 years old: Presbyopia 100 - 250 degrees; 60 - 65 years old: Presbyopia above 250 degrees or use a magnifying glass.

[0005] 4. Measure the axial length of the eye and compare it with the normal axial length of peers of the same age to determine whether it is too long or too short; Measure the corneal base curve degree for use with contact lenses; Measure the pupillary distance for use with frame glasses; Due to technological limitations, currently, there is no machine in the world that can automatically dispense glasses using a computer. The problem of refractive error of the human eye requires an ophthalmologist to perform lens - inserting operations to prescribe glasses, which also brings an efficient entry opportunity for DeepSeek. Because DeepSeek, as an assistant to a virtual ophthalmologist, has deep - learning capabilities. It can quickly and accurately identify and analyze the refractive data of people wearing glasses according to the internationally common refractive criteria. It can also predict the risk of refractive error of patients by reading a large amount of medical record data of patients, thus adding an intelligent forward - looking element to the ophthalmology industry. Obviously, it also makes the applicant and inventor of this patent think about a problem. The high - profile intervention of DeepSeek under the big - data model has actually brought high technology to the traditional ophthalmology industry of refractive power adjustment. Since then, it has opened a corner of the innovation of artificial intelligence technology in the optical glasses industry. Therefore, the advent of the portable refractive power examination and diagnosis instrument based on DeepSeek has important practical significance. At least, it has brought a revolution in line with the times to the ophthalmology field. Summary of the Invention

[0006] The specific content is as follows: The portable refractive power examination and diagnosis instrument based on DeepSeek consists of a base, a handle, operation buttons, an LCD step, pan - tilt stepper motor A, pan - tilt stepper motor B, pan - tilt stepper motor C, pan - tilt stepper motor D, a tablet computer, a support link of the tablet computer, and a refractive power examination and diagnosis instrument lens. The key points are as follows: The portable refractive power examination and diagnosis instrument based on DeepSeek is a refractive power examination and diagnosis device using a four - axis pan - tilt. This device can be operated by an ophthalmologist or optometrist holding the handle, or can be fixed on the examination table through the base for operation. For this reason, the handle is specially engraved with anti - slip convex dot surfaces; An operation button and an LCD step are also extended from the handle, and a power button, a direction control button, a camera diagnosis button, a tracking button, and an LCD display panel are arranged on the operation button and the LCD step; The handle also has a calibration lock key, a zoom adjustment knob, and a TYPE-C socket Q that communicates with the TYPE-C socket L of the tablet computer. At the same time, the TYPE-C socket L and the TYPE-C socket Q also serve as charging ports for the tablet computer and the four-axis gimbal respectively. The core components of the portable diopter based on DeepSeek are three: the head component is the diopter lens, the diagnostic analysis component based on DeepSeek is a tablet computer, and the four-axis pan-tilt device controlled by the pan-tilt stepper motor connected to the handle supports the three-dimensional movement of the diopter. The lens of the diopter diagnostic instrument is connected to the CCD lens on the tablet computer through a hook. The lens of the diopter diagnostic instrument is an objective lens, responsible for the first imaging magnification to form an inverted real image, and the CCD lens on the tablet computer is an eyepiece, which can form an upright virtual image. The lens of the diopter diagnostic instrument is equipped with an aperture adjustment knob, and the aperture adjustment knob has five outputs, namely, large aperture, small aperture, slit, center grid and red-free filter; The lens of the diopter diagnostic instrument also has a diopter compensation sheet slot, which can be inserted with 25 diopter compensation sheets, namely: 0D, ±1D, ±2D, ±3D, ±4D, ±5D, ±6D, ±8D, ±10D, ±12D, ±15D, ±20D, -25D, -35D. This shows that due to the limitation of technology level, there is no machine in the world that can automatically match glasses with computers at present. Therefore, ophthalmologists have to manually insert the sheets to obtain the patient's recognition of the refractive compensation. Fortunately, the lens of the diopter diagnostic instrument has reserved such a slot; In order to further see the patient's pupil condition, the diopter diagnostic instrument lens is equipped with a focus adjustment knob and two super luminescent diodes SLD with a wavelength of 1050nm. The super luminescent diode SLD is an auxiliary light source between laser and ordinary light emitting diode, with the characteristics of high brightness, low phase interference and excellent light penetration. However, the wavelength and power density of the super luminescent diode SLD will cause certain damage to the eyes, because after the high-power density SLD light enters the pupil, it can not only allow the doctor to see the internal condition of the pupil, but also gather a large amount of light energy on the patient's retina, thereby The temperature of the retinal photoreceptor layer rises rapidly, causing photoreceptor cell burns or coagulation, degeneration and necrosis, resulting in irreversible visual damage and even clouding of the lens and cornea. Therefore, in order to eliminate the potential dangers of high-energy light emitted by SLD, the eyes of the examinee only need to be placed about 25 cm in front of the lens of the diopter diagnostic instrument. In addition, a super-luminescent diode SLD dimming knob is specially arranged on the lens of the diagnostic instrument to facilitate the doctor's intervention at any time. In addition, the portable diopter diagnostic instrument based on DeepSeek also has the function of automatically limiting the SLD irradiation time to less than 500 seconds. The tablet computer based on the diagnostic analysis component of DeepSeek is connected to the four-axis gimbal through the tablet computer's supporting rod. A very thin NdFeB magnet suction cup is attached to the surface of the tablet computer's supporting rod. This strong NdFeB magnet suction cup is attracted to the rotating shaft H, which can ensure that the tablet computer and the tablet computer's supporting rod can be removed from the rotating shaft H at any time. During the examination, the TYPE-C socket L on the tablet is connected to the TYPE-C socket Q on the handle through a double TYPE-C plug cable. The tablet is a tablet that supports artificial intelligence chips, uses a multi-core processor, integrates an ultra-low power coprocessor (ULP), supports edge computing and accelerated reasoning capabilities in DeepSeek mode, and provides a hardware-supported artificial intelligence service system for patients' refractive power detection. In this way, the doctor only needs to press the calibration lock button and the camera diagnosis button on the handle in turn, and the tablet can extract the refractive power features from the data classification according to the internationally accepted refractive criteria, including: The criteria for myopia or hyperopia are: mild is 0-300 degrees, moderate is 300-600 degrees, and severe is above 600 degrees. The criteria for the degree and axis of astigmatism are: mild is 0-100 degrees, moderate is 100-200 degrees, severe is 200-300 degrees, and extreme astigmatism is more than 300 degrees. The criterion for the degree of presbyopia is first predicted based on age as follows: 40-50 years old: 100 degrees of presbyopia, 50-60 years old: presbyopia 100-250 degrees, Ages 60 - 65: Presbyopia of over 250 degrees or with a magnifying glass, Measure the axial length of the eye and compare it with the normal axial length of peers of the same age to determine if it is too long or too short; measure the corneal base arc degree for use in wearing contact lenses; measure the pupillary distance for use in wearing frame glasses; then, DeepSeek gives clinical diagnostic opinions on the screen through a tablet computer for doctors' reference; The four - axis gimbal supports the three - dimensional movement of the diopter examination instrument. The operation of the four - axis gimbal is associated with the control buttons on the handle. Among them, the power button controls the on - off operation, the direction control buttons control the up, down, left, and right movement of the gimbal, and the zoom adjustment knob controls the gimbal's stepper motor B to make a forward or backward movement, which is equivalent to adjusting the height of the gimbal.

[0007] Furthermore, the handles are all injection - molded from safe, environmentally friendly, and flame - retardant engineering plastics.

[0008] Furthermore, under the control of the direction control buttons and the zoom adjustment knob, the four - axis gimbal drives the clamping link M to make a 360 - degree horizontal rotation through the gimbal stepper motor A, drives the rotating shaft E to make a forward or pitching movement through the gimbal stepper motor B, drives the rotating shaft G and the clamping link N on the rotating shaft G to make a 360 - degree horizontal rotation under the forward or pitching angle through the gimbal stepper motor C, and drives the rotating shaft H and the clamping link of the connected tablet computer through the gimbal stepper motor D, making the tablet computer rotate on the horizontal plane.

[0009] Furthermore, the control of the gimbal stepper motor uses a domestic high - performance dual - core processor ESP32 - S3 with 32 bits. This chip uses a QFN56 package and a low - power supply method, and supports fixed - point, floating - point, DSP, Bluetooth, and WiFi operations.

[0010] Furthermore, after pressing the tracking button, the four - axis gimbal can automatically track the patient's wandering gaze. When the wandering distance is too large, the tablet computer can also emit sound through the sound output hole via the APP voice applet to remind the patient not to move.

[0011] Furthermore, the display division of labor between the screen on the tablet computer and the LCD display panel on the handle is as follows: The screen on the tablet computer shows the patient's diopter data and the diagnostic opinions based on DeepSeek intervention. There is also a complete prescription for optometry and glasses fitting, including myopia and hyperopia degrees, astigmatism degree and axis, presbyopia degree, pupil distance and base curve, and eye axis data. The degrees of myopia, hyperopia, and astigmatism are given according to mild, moderate, and severe levels respectively. And DeepSeek makes a beneficial assessment based on the detection results. Whether the patient can undergo laser surgery. If the patient is suitable for wearing frame glasses, DeepSeek will recommend the possibility of wearing daily contact lenses or contact lenses that can correct high astigmatism. Therefore, the appearance of DeepSeek greatly reduces the outpatient pressure on doctors, and patients can also clearly understand their eye conditions and solve the problems faced by traditional doctors in seeing patients through DeepSeek; the LCD display panel shows the current operating conditions of the four-axis cloud platform.

[0012] Furthermore, the diopter detector is powered by 18650 type lithium iron phosphate batteries and complies with YY 9706.102-2021 "Medical Electrical Equipment - Part 1-2: General Requirements for Basic Safety and Essential Performance - Collateral Standard: Electromagnetic Compatibility - Requirements and Tests" issued by the National Medical Products Administration. This standard is equivalent to IEC 60601-1-2:2007 and will not cause electromagnetic interference to other electrical equipment.

[0013] Furthermore, in order to ensure the safety and performance of the device in the electromagnetic environment and reduce the market access threshold, the four-axis cloud platform of the portable diopter detector is not controlled by traditional permanent magnet brushless micro-motors or servo motors, but is driven by a two-phase six-step stepper motor with an amorphous alloy body as the core material. Since the amorphous alloy body has very low coercivity and high magnetic permeability, and the stepper motor belongs to an open-loop control mechanism, its start, stop, and reverse are rapid, and it has good stability during low-speed operation, thus greatly reducing the complexity of the system and its external electromagnetic interference is small.

[0017] The following combines with the attached drawings to illustrate the detailed implementation manner of the present invention. It should be noted that for simplicity, all installation screws and the internal composition of the stepper motors in the four - axis pan - tilt are omitted in the views.

[0018] The portable diopter examination instrument based on DeepSeek is composed of a base (1), a portable diopter examination instrument handle (2), operation keys and an LCD step (3), a pan - tilt stepper motor A (4), a pan - tilt stepper motor B (5), a pan - tilt stepper motor C (6), a pan - tilt stepper motor D (7), a tablet computer (8), a clamping link for the tablet computer (7 - 2), and a diopter examination instrument lens (9). The key points are as follows: The portable refraction diagnostic instrument based on DeepSeek is a refraction diagnostic device using a four-axis gimbal. The device can be operated by an ophthalmologist or optometrist by holding a handle (2), or can be placed on a diagnosis and treatment table for fixed operation via a base (1). For this purpose, the handle (2) is specially engraved with a handle anti-slip convex surface (2-1); An operation button and an LCD step (3) are also extended from the handle (2), and the operation button and the LCD step (3) are provided with a power button (3-1), a direction control button (3-2), a camera diagnosis button (3-3), a tracking button (3-4), and an LCD display panel (3-5); The handle (2) is also provided with a calibration lock key (3-6), a zoom adjustment knob (3-7), and a TYPE-C socket Q (3-8) for communicating with a TYPE-C socket L (8-1) of a tablet computer (8); at the same time, the TYPE-C socket L (8-1) and the TYPE-C socket Q (3-8) also serve as charging ports for the tablet computer (8) and the four-axis gimbal, respectively; The core components of the portable diopter diagnostic instrument based on DeepSeek are three: the head component is the diopter diagnostic instrument lens (9), the diagnostic analysis component based on DeepSeek is a tablet computer (8), and the four-axis pan-tilt device controlled by the pan-tilt stepper motor connected to the handle (2) supports the three-dimensional movement of the diopter diagnostic instrument; The diopter diagnostic instrument lens (9) is connected to the CCD lens (8-3) on the tablet computer via a hook (9-2); the diopter diagnostic instrument lens (9) is an objective lens responsible for first imaging magnification to form an inverted real image; the CCD lens (8-3) on the tablet computer is an eyepiece to form an upright virtual image; The diopter diagnostic instrument lens (9) is provided with an aperture adjustment knob (9-4), and the aperture adjustment knob (9-4) is divided into five outputs, namely, a large aperture, a small aperture, a slit, a central grid and a red-free filter; The refractive diagnostic instrument lens (9) also has a refractive compensation sheet slot (9-6) into which 25 types of refractive compensation sheets can be inserted, namely: 0D, ±1D, ±2D, ±3D, ±4D, ±5D, ±6D, ±8D, ±10D, ±12D, ±15D, ±20D, -25D, -35D. This indicates that, due to the limitation of the technical level, there is no machine in the world that can automatically fit glasses using a computer. Therefore, ophthalmologists have to manually insert the sheet to obtain the patient's recognition of the refractive compensation. Fortunately, such a slot is reserved on the refractive diagnostic instrument lens (9); To further clarify the condition of the patient's pupils, the diopter examination instrument lens (9) is equipped with a focus adjustment knob (9-3) and two superluminescent diodes SLDs (9-1) with a wavelength of 1050 nm. The superluminescent diode SLD (9-1) is an auxiliary light source between a laser and an ordinary light-emitting diode, featuring high brightness, low phase interference, and excellent light penetration. However, the wavelength and power density of the superluminescent diode SLD will cause certain damage to the eyes. Because after the high-power density SLD light enters the pupil, it can enable the doctor to see the internal condition of the pupil, but it will also accumulate a large amount of light energy on the patient's retina, causing the temperature of the photoreceptor cell layer of the retina to rise rapidly, resulting in the burning or coagulation and necrosis of photoreceptor cells, causing irreversible vision damage, and even leading to lens and corneal opacity. Therefore, to eliminate the potential danger brought by the high-energy light emitted by the SLD, the eyes of the examinee only need to be placed about 25 centimeters in front of the diopter examination instrument lens (9). Moreover, a superluminescent diode SLD dimming knob (9-5) is specifically arranged on the examination instrument lens (9) for the doctor to intervene at any time. In addition, the portable diopter examination instrument based on DeepSeek also has the function of automatically limiting the irradiation time of the SLD within 500 seconds; The diagnostic analysis component tablet computer (8) based on DeepSeek is connected to the four-axis gimbal through the tablet computer's clamping link (7-2). A very thin neodymium iron boron magnet suction cup (7-3) is surface-mounted on the tablet computer's clamping link (7-2). This powerful neodymium iron boron magnet suction cup (7-3) is attracted to the rotating shaft H (7-1), which can ensure that the tablet computer (8) and the tablet computer's clamping link (7-2) can be removed from the rotating shaft H (7-1) at any time; During the examination work, the TYPE-C socket L (8-1) on the tablet computer (8) is connected to the TYPE-C socket Q (3-8) on the handle (2) through a double TYPE-C plug cable. The tablet computer (8) is a tablet computer that supports an artificial intelligence chip, uses a multi-core processor, integrates an ultra-low power co-processor (ULP), and supports edge computing and accelerated inference capabilities in the DeepSeek mode, thus providing an artificial intelligence service system based on hardware support for the diopter detection of patients. In this way, as long as the doctor presses the calibration lock key (3-6) and the photographic diagnosis key (3-3) on the handle (2) in sequence, the tablet computer (8) can extract diopter features from the data classification according to the internationally common diopter criteria, where: The criteria for myopia and hyperopia degrees are: mild is 0-300 degrees, moderate is 300-600 degrees, and high is above 600 degrees, The criteria for astigmatism degree and axis are as follows: mild is 0 - 100 degrees, moderate is 100 - 200 degrees, severe is 200 - 300 degrees, and ultra-high astigmatism is above 300 degrees. The criteria for presbyopia degree are predicted according to age as follows. 40 - 50 years old: presbyopia of 100 degrees. 50 - 60 years old: presbyopia of 100 - 250 degrees. 60 - 65 years old: presbyopia above 250 degrees or with a magnifying glass. Measure the axial length of the eye and compare it with the normal axial length of peers of the same age to determine whether it is too long or too short; measure the corneal base curve degree for use in wearing contact lenses; measure the pupil distance for use in wearing frame glasses; then, DeepSeek gives clinical diagnosis opinions on the screen through the tablet computer (8) for doctors' reference. The four-axis gimbal supports the three-dimensional movement of the diopter examination instrument. The operation of the four-axis gimbal is associated with the control buttons on the handle (2). Among them, the power button (3 - 1) controls the power-on and power-off operations, the direction control button (3 - 2) controls the up, down, left, and right movement of the gimbal, and the zoom adjustment knob (3 - 7) controls the gimbal stepping motor B (5) to make a forward or backward movement, which is equivalent to adjusting the height of the gimbal.

[0019] Furthermore, the handle (2) is formed by injection molding of safe, environmentally friendly, and flame-retardant engineering plastics.

[0020] Furthermore, under the control of the direction control button (3 - 2) and the zoom adjustment knob (3 - 7), the four-axis gimbal drives the clamping link M (4 - 1) to make a 360-degree horizontal rotation through the gimbal stepping motor A (4), drives the rotating shaft E (5 - 1) to make a forward or pitching movement through the gimbal stepping motor B (5), drives the rotating shaft G (6 - 1) and the clamping link N (6 - 2) on the rotating shaft G (6 - 1) to make a 360-degree horizontal rotation at a forward or pitching angle through the gimbal stepping motor C (6), and drives the rotating shaft H(7 - 1) and the clamping link (7 - 2) of the connected tablet computer through the gimbal stepping motor D (7), so that the tablet computer (8) makes a rotation on the horizontal plane.

[0021] Furthermore, the control of the gimbal stepping motor uses a 32-bit domestic high-performance dual-core processor ESP32-S3. This chip uses a QFN56 package and a low-power supply method, and supports fixed-point, floating-point, DSP, Bluetooth, and WiFi operations.

[0022] Furthermore, after pressing the tracking button (3 - 4), the four-axis gimbal can automatically track the patient's wandering eyes. When the wandering distance is too large, the tablet computer (8) can also emit sound through the sound output hole (8 - 2) through the APP voice applet to remind the patient not to move.

[0023] Furthermore, the display division of labor between the screen on the tablet computer (8) and the LCD display panel (3-5) on the handle (2) is as follows: the screen on the tablet computer (8) presents the diopter data of the patient and the diagnostic opinions based on DeepSeek intervention. There is also a complete prescription for optometry and glasses fitting, including myopia, hyperopia degrees, astigmatism degrees and axes, presbyopia degrees, pupil distance and base curve, and eye axis data. And it gives the degrees of myopia, hyperopia, and astigmatism according to mild, moderate, and severe levels respectively. And DeepSeek makes a beneficial assessment based on the detection results on whether the patient can undergo laser surgery. If the patient is suitable for wearing frame glasses, DeepSeek will recommend the possibility of wearing daily contact lenses or contact lenses that can correct high astigmatism. Therefore, the appearance of DeepSeek greatly reduces the outpatient pressure on doctors, and patients can also clearly understand their eye conditions, solving the problems faced by traditional doctors in seeing patients. The LCD display panel shows the current operating conditions of the four-axis gimbal.

[0024] Furthermore, the diopter detector is powered by 18650 type lithium iron phosphate batteries and complies with YY9706.102-2021 "Medical Electrical Equipment - Part 1-2: General Requirements for Basic Safety and Essential Performance - Collateral Standard: Electromagnetic Compatibility - Requirements and Tests" issued by the National Medical Products Administration. This standard is equivalent to IEC60601-1-2:2007 and will not produce electromagnetic interference to other electrical equipment.

[0025] Furthermore, to ensure the safety and performance of the device in the electromagnetic environment and reduce the market access threshold, the four-axis gimbal of the portable diopter detector is not controlled by a traditional permanent magnet brushless micro-motor or servo motor, but is driven by a two-phase six-step stepper motor with an amorphous alloy body as the core material. Since the amorphous alloy body has a very low coercivity and high magnetic permeability, and the stepper motor belongs to an open-loop control mechanism, its start, stop, and reverse are rapid, and it has good stability during low-speed operation, thus greatly reducing the complexity of the system and its external electromagnetic interference. Beneficial Effects

[0026] 1. This invention application combines the DeepSeek data large model, the diopter detector lens, the tablet computer, and the electric gimbal into one, which can very conveniently provide patients with an accurate digital diopter detection solution and an excellent user vision correction detection experience; in the field of ophthalmology, this is an unprecedented AI-based enabling innovation.

[0027] 2. As an excellent assistant to virtual ophthalmologists, DeepSeek has deep learning capabilities. It can quickly and accurately identify and analyze the refractive power data of people wearing glasses according to internationally common refractive criteria. It can also predict the risk of refractive errors in patients by reading a large amount of medical record data of patients, thus adding an intelligent forward-looking element to the ophthalmology industry. Obviously, it also makes the patent applicant and inventor think about a problem. The high-profile intervention of DeepSeek under the big data model has actually brought high technology to the traditional ophthalmology industry of refractive power adjustment. Since then, in the regular optical glasses industry, a corner of artificial intelligence technology innovation has been opened. Therefore, the advent of the portable refractive power detector based on DeepSeek has important practical significance. At least, it has brought a truly contemporary revolution to the current ophthalmology field.

[0028] 3. This invention application has increased the intensity of digital update and the latest artificial intelligence technology in traditional refractive power detection. It uses a tablet computer to perform data modeling and analysis with the DeepSeek model to form a real glasses prescription. Patients can conveniently go to a glasses store to fit glasses based on this prescription.

[0029] 4. Obviously, the emergence of DeepSeek technology is equivalent to having a newly employed digital "AI doctor" in the ophthalmology industry. Although it is virtual, cannot make decisions alone, and is not a real ophthalmologist in the true sense, it can assist professional doctors in providing treatment services, thus greatly reducing the outpatient pressure on ophthalmologists. Combining the age and vision conditions of the examinee, doctors will make further user-friendly treatment opinions with the deep intervention of the DeepSeek portable refractive power detector; more significantly, the DeepSeek portable refractive power detector also provides an AI-based inspection report for underage patients, predicting how many years later the examinee will develop myopia, hyperopia, and astigmatism, and predicting how many years later middle-aged and elderly people will still need to have myopia surgery. By using artificial intelligence to predict the future vision change trend of patients, patients can pay attention to eye care and make psychological preparations in advance.

[0030] 5. More realistically, using the DeepSeek portable refractive power detector to treat refractive eye diseases such as myopia, hyperopia, and astigmatism also eliminates the trouble of patients queuing up to see a doctor shoulder to shoulder in the hospital. Therefore, the application prospect of this device is very broad and will surely win the welcome of hospitals, adolescent ophthalmology treatment centers, medical workers, and patients.
