Description
Technical Field
[0001] This utility model relates to the technical field of heterophoria detection equipment, specifically an intelligent eye position detection device. Background Technology
[0002] Latent strabismus mainly includes esophoria, exophoria, and hyperphoria. Common symptoms of latent strabismus include eye strain, such as headaches, periorbital pain, or retrobulbar pain after prolonged reading. In severe cases, nausea and vomiting may occur. These symptoms usually disappear completely when one eye is covered and only the other is used for reading. Patients with latent strabismus may also experience intermittent strabismus and diplopia after prolonged visual exertion.
[0003] Currently, existing methods for detecting heterophoria are difficult to use due to the inherent complexity of the optical instruments used in the process. Furthermore, the results require calculations and thus necessitate guidance from professionals in the relevant fields. For example, many optical shops employ a dedicated staff member to guide the test taker and perform data calculations, resulting in low testing efficiency and long waiting times for those being tested. Therefore, these methods do not meet the current needs. To address this, we propose an intelligent eye position detection device. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Example 1 aims to address the problem of low detection efficiency due to the need for professional guidance during testing, and the high production cost and inconvenience of existing eye position detection devices that display a cursor on a screen. Please refer to [link to example 1]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An intelligent eye position detection device includes an instrument housing 1, within which a main controller 3 is installed. The main controller 3 includes a control unit 30, a voice unit 31, an input port 32, and an output port 33. A polarizing composite sheet 2 is attached to a light-transmitting plate 11. A visual target layer 23 is directly printed by UV printing on the side of the polarizing composite sheet 2 away from the viewer's observation. The control unit 30 is electrically connected to the main controller 3. The voice unit 31 is connected to the main controller 3 through the input port 32 and the output port 33. The voice unit 31 broadcasts instructions issued by the main controller 3. During eye position detection, the person being tested wears linearly polarized glasses (the polarization direction of the left and right eyes of the polarized glasses corresponds to the X-axis polarization film 21 and the Y-axis polarization film 22 of the polarizing composite sheet 2). The device guides the subject to eye position detection through voice interaction. The main controller 3 is connected to the Internet of Things (IoT) 34 via communication. The IoT 34 is used to store user information. The main controller 3 is connected to a ranging unit 35 through input port 32 and output port 33. The ranging unit 35 acquires the distance between the pupil and the instrument box 1 and the interpupillary distance between the two eyes, and transmits the data signals to the main controller 3. The ranging unit 35, in cooperation with the voice unit 31 through the main controller 3, guides the subject to adjust the position, collects the detection information, and transmits it to the main controller 3 for data analysis, so that the subject can directly obtain the detection results, thereby reducing the detection difficulty through human-computer interaction.
[0032] It also includes a polarizing assembly 2, which is placed inside the instrument housing 1. The top of the instrument housing 1 has an open structure, and a light-transmitting plate 11 is provided on the top of the instrument housing 1 to close its opening. The polarizing assembly 2 placed inside the instrument housing 1 can be observed through the light-transmitting plate 11. The polarizing assembly 2 consists of an X-axis polarizing film 21 with an X-axis polarization angle and a Y-axis polarizing film 22 with a Y-axis polarization angle. The X-axis polarizing film 21 and the Y-axis polarizing film 22 are combined and spliced on the same optical plane. A target layer 23 is printed on the polarizing assembly 2. The X-axis and Y-axis markings of the target layer 23 are on the same straight optical path as the X-axis polarizing film 21 and the Y-axis polarizing film 22, respectively. The X-axis and Y-axis markings of the target layer 23 are on the corresponding optical paths of the X-axis polarizing film 21 and the Y-axis polarizing film 22, respectively, in order to replace the display of the target on the screen.
[0033] In this embodiment, the visual target layer 23 is directly printed onto the polarization assembly 2, thereby saving production costs, simplifying the overall structure of the testing equipment, and making it easy to carry and use. At the same time, the high-definition printing method makes the display of the visual target softer, which is beneficial for the tester to observe the polarization assembly 2 with a more relaxed eye. In order to relax the requirements of the tester's posture during the test, so that the tester can still observe and test even if the tester's head is slightly turned, thereby reducing the difficulty of the test, quarter-wavelength retardation films 20 with opposite polarization rotation effects can be covered on the X-axis polarization film 21 and the Y-axis polarization film 22 respectively. The quarter-wavelength retardation film 20 is used in conjunction with the X-axis polarization film 21 and the Y-axis polarization film 22 to convert linearly polarized light into circularly polarized light. At this time, during eye position testing, the tester wears circularly polarized glasses, and the left and right eye polarization detection directions of the circularly polarized glasses correspond to the rotation directions of the X-axis polarization film 21 and the Y-axis polarization film 22 of the polarization assembly 2.
[0034] In this embodiment, various units are connected through the input port 32 and output port 33 of the main controller 3. The voice unit 31 uses a speaker and microphone connected to a voice processing chip for input and playback, respectively, and can be integrated into the instrument housing 1. The ranging unit 35 uses a camera or light detection sensor to acquire data. The ranging unit 35 can also be connected to the main controller 3 through the input port 32 and output port 33 and can be integrated into the instrument housing 1. It is only necessary to let its detection end pass through the outer wall of the instrument housing 1 to ensure the accuracy of the detection results. The main controller 3 is powered by a battery directly installed on the instrument housing 1. The highly integrated instrument housing 1 can greatly improve its portability.
[0035] It should be noted that the shape of the X-axis polarizing film 21 and the Y-axis polarizing film 22, as well as the structure at the splicing point, can be adjusted and changed according to the actual situation to achieve better splicing and facilitate the printing of more content.
[0036] Example 2 aims to address how to reduce data errors caused by improper operation during self-service measurement. Do not wear the corresponding testing glasses during measurement. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 1 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The instrument housing 1 is equipped with a backlight device 10, which consists of several LEDs 100. The LEDs 100 are evenly distributed along the XY axis of the XY target layer 23. The backlight device 10, composed of LEDs 100, emits light that can illuminate the corresponding target and pass through the light-transmitting plate 11 on the instrument housing 1. A polarization detection device is provided on the side closer to the eye in the optical path between the instrument housing 1 and the pupil. The polarization detection device works on the same principle as the linear polarized glasses in Embodiment 1. A cut-in lens is provided in the optical path between the instrument housing 1 and the pupil to increase refractive adjustment in the optical path. A cut-in prism is also provided in the optical path between the instrument housing 1 and the pupil. A liquid crystal light valve is also provided in the optical path between the instrument housing 1 and the pupil. The liquid crystal light valve is controlled to close and open, which is equivalent to closing and opening the eyes, reducing measurement errors.
[0037] In this embodiment: no special testing glasses are required during measurement. Instead, the measurement is performed using a polarized light detection device. The detection distance is relatively fixed. In a bright environment, the backlight device 10 composed of LED lights 100 can remain off. External light shines through the light-transmitting plate 11 onto the polarization assembly 2. The optotype layer 23 on the polarization assembly 2 reflects the light, allowing the user to use the intelligent eye position detection device in a bright environment. In a dim environment, the backlight device 10 composed of LED lights 100 emits light, which illuminates the corresponding optotype and shines through the light-transmitting plate 11 on the instrument housing 1, enabling the user to use the intelligent eye position detection device in the absence of a light source or in dim light.
[0038] It should be noted that when using the prism method for detection, the corresponding optical path between the lens of the polarizing detection device and the instrument box 1 can be achieved by setting a prism to meet the hardware requirements of the prism method for detection.
[0039] The working principle of this utility model is as follows: First, the splicing area between the X-axis polarizing film 21 and the Y-axis polarizing film 22 coincides with the XY markings of the visual target layer 23. The X-axis polarizing film 21 and the X-axis markings of the visual target layer 23 work together to detect esophoria / exophoria. The positive half-axis of the X-axis marking indicates the convergence of esophoria, and the negative half-axis indicates the convergence of exophoria. The Y-axis polarizing film 22 and the Y-axis markings of the visual target layer 23 work together to detect left / right hypertropia. The positive half-axis of the Y-axis marking indicates left-eye hypertropia, and the negative half-axis indicates right-eye hypertropia.
[0040] This intelligent eye position detection device can simultaneously detect horizontal and vertical eye positions. The visual distance between the examiner's eye and the polarizing filter 2 is 6m or 40cm. The distance between the examiner's eye and the polarizing filter can be adjusted by an incisional lens, such as a convex lens, to allow for close-range adjustment between the examiner's eye and the polarizing filter 2. Moreover, depending on the detection needs, incisional lenses, liquid crystal light valves, and prisms can be selectively installed. The incision method can be a rotary incision with multiple devices, or an incision in the up, down, left, and right directions. At the same time, the device can select whether to turn on the backlight device 10 and adjust the brightness of the backlight device 10 according to the brightness of the detection environment. In addition, additional accessories, such as high-precision measuring instruments and scanning devices, can be installed on the input port 32 and output port 33 reserved on the main controller 3.
[0041] During the test, the subject observes the polarization combination plate 2 through the polarization detection device. Based on the principle of polarization, the light waves polarized by the target polarization plate can only pass through the corresponding lens of one of the left or right eyes corresponding to the test plate, thus achieving separate vision for the left and right eyes. The lens of the polarization detection device is composed of the corresponding X-axis polarization film 21 or Y-axis polarization film 22. Subsequently, the ranging unit 35 in the instrument box 1 detects the distance between the pupil and the instrument box 1 and transmits the detected data signal to the main controller 3. The main controller 3 issues voice commands through the voice unit 31 to guide the test. Then, the subject transmits the observed information to the main controller 3 through the voice unit 31. After processing and calculating the data, the main controller 3 directly announces the calculation results through the voice unit 31.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
