[Figure 3] This is an example of an inspection screen displayed on the display unit. [Figure 4] This is an example of a language selection guidance screen displayed on the display unit. [Figure 5] This is an example of a home screen displayed on the display unit. [Modes for carrying out the invention]

[0010] <Overview> The outline of the ophthalmic device of this embodiment will be described below. The items classified in <> below can be used independently or in relation to each other.

[0011] The ophthalmic device of this embodiment is a device for examining the eye under examination. For example, the ophthalmic device may be an objective optometry device that objectively measures the optical properties of the eye under examination (refractive power, axial length, corneal shape, etc.). For example, the ophthalmic device may be an ophthalmic imaging device that photographs the anterior segment of the eye under examination and acquires anterior segment image data of the eye under examination, corneal shape data of the eye under examination, etc. Alternatively, for example, the ophthalmic device may be an ophthalmic imaging device that photographs the fundus of the eye under examination and acquires frontal image data of the fundus of the eye under examination, tomographic image data of the fundus of the eye under examination, etc. That is, it may be at least one of a refractive power measuring device, a corneal curvature measuring device, a corneal shape measuring device, an intraocular pressure measuring device, an axial length measuring device, a fundus camera, OCT (Optical Coherence Tomography), SLO (Scanning Laser Ophthalmoscope), etc.

[0012] <Notification methods> The ophthalmic device of this embodiment may include an announcement means. The announcement means is a means for announcing to the subject. For example, the announcement means may be at least any one of a display means (for example, display unit 75), a voice generation means (for example, announcement output unit 89), and the like.

[0013] <Display control means> The ophthalmic device of this embodiment may include a display control means (for example, control unit 70). The display control means causes the display means to display a first language setting screen (for example, language selection guidance screen 810) for setting the language of the announcement, which is different from the condition setting screen for setting the examination conditions of the subject eye.

[0014] The condition setting screen may be a screen on which the examination conditions of the subject eye can be set. For example, the condition setting screen may be a screen on which at least any one of the following conditions can be set: input of identification information for identifying the examiner, input of identification information for identifying the subject, selection of the measured eye, and the like. For example, the condition setting screen may be a home screen (for example, home screen 900) before proceeding to the examination of the subject eye. For example, the condition setting screen may be an examination screen (for example, examination screen 800) including at least an observation image of the subject eye and a call button for calling a second language setting screen for setting the language of the announcement. That is, the condition setting screen may be a screen on which the language of the announcement can be selected by calling the second language setting screen. The second language setting screen will be described later.

[0015] The first language setting screen may include a list of a plurality of languages and be a screen on which an arbitrary language can be selected based on the list. That is, the first language setting screen may be a screen on which the language of the announcement can be selected using the list of languages on the first language setting screen.

[0016] The first language setting screen may further include guidance information (e.g., operation instruction screen 811) for guiding the selection of the announcement language, and setting buttons (e.g., language selection buttons 812) corresponding to a plurality of languages. For example, the guidance information may be icons or pictograms, or may be messages corresponding to each language.

[0017] The second language setting screen may include a list of a plurality of languages and be a screen on which any language can be selected based on the list. That is, the second language setting screen may be a screen on which the announcement language can be selected using the list of languages on the second language setting screen. In this embodiment, the second language setting screen may be provided as a screen different from the first language setting screen, or may be provided as a common screen with the first language setting screen.

[0018] The display control means may cause the display means to display the first language setting screen as the initial screen every time the examination of the subject eye ends. That is, every time the subject eye changes, the display means may display the first language setting screen as the initial screen. Thereby, the announcement language suitable for the subject can be easily set each time the examination is performed.

[0019] The display control means may cause the display means to display the condition setting screen or the first language setting screen according to the mode switched by the mode switching means described later. For example, in the first mode, when the subject cannot understand the announcement language, it can be appropriately changed from a predetermined language set in advance to the language desired by the subject. For example, in the second mode, every time the subject changes, the announcement language can be pre-selected according to the language used by the subject. Therefore, the mode can be switched according to the examination status of the subject, and the announcement language desired by the subject can be easily selected.

[0020] <Mode switching means> The ophthalmic apparatus of this embodiment may include a mode switching means (for example, a control unit 70). The mode switching means switches between a first mode in which the condition setting screen is displayed on the display means as the initial screen each time the examination of the eye is completed, and a second mode in which the first language setting screen is displayed on the display means as the initial screen each time the examination of the eye is completed.

[0021] The first mode may be a mode for the examiner to select the language of the announcements. For example, the first mode may be selected when the examiner is conducting the test while interacting with the subject. The language of the announcements may be changed if the subject does not understand the pre-set language of the announcements. The second mode may be a mode for the subject to select the language of the announcements. For example, the second mode may be selected when the subject is conducting the test on their own. The subject may change the language of the announcements to one that they can understand.

[0022] <Control means> The ophthalmic apparatus of this embodiment may include control means (for example, a control unit 70). Based on an operation signal from an operation means for selecting the language of the announcement, the control means outputs an announcement in the selected language from a notification means and proceeds with the examination of the eye under examination. For example, the control means may output an announcement and proceed with the examination based on an operation signal from an operation means operated by the examiner. Alternatively, for example, the control means may output an announcement and proceed with the examination based on an operation signal from an operation means operated by the subject. The operation means may be a button or the like provided on at least one of the ophthalmic apparatus body, a controller connected to the ophthalmic apparatus by wired or wireless communication, etc., or a button or the like displayed on a display means.

[0023] The control means may output an announcement in the selected language from the notification means based on an operation signal from a setting button (e.g., a language selection button 812) included in the first language setting screen, and proceed with the eye examination. Alternatively, the control means may output an announcement in the selected language from the notification means based on an operation signal from a setting button included in the second language setting screen, and proceed with the eye examination.

[0024] The control means may set the announcement language to a preset initial language each time the eye examination is completed. For example, the control means may set the announcement language to the initial language each time the eye examination is completed in the first mode. Alternatively, for example, the control means may set the announcement language to the initial language each time the eye examination is completed in the second mode. This reduces the effort required for the examiner to revert the announcement language back to its original setting after the eye examination is completed, and also shortens the time required to revert the announcement language.

[0025] If the second mode is set, the control means may change the operation control for prohibiting the operation of the ophthalmic device after the announcement language has been selected. For example, the operation control for prohibiting the operation of the ophthalmic device may be a control that prohibits the transmission or reception of operation signals from the operation means. In other words, the input of operation signals from the operation means may be disabled. Alternatively, for example, the operation control for prohibiting the operation of the ophthalmic device may be a control that outputs a message to the subject prohibiting operation. For example, the message may be announced by a notification means. Alternatively, for example, the operation control for prohibiting the operation of the ophthalmic device may be a control that changes the display of the display means. For example, the condition setting screen may be changed to a different screen, such as blacking out the condition setting screen. Alternatively, for example, the operation control for prohibiting the operation of the ophthalmic device may be a control that accepts an input signal from the chin rest detection means (e.g., chin rest sensor 3c). In this case, the input signal from the detection means may be disabled before the announcement language is selected, and the input signal from the detection means may be enabled after the announcement language is selected.

[0026] Furthermore, the above-mentioned control mechanisms may be implemented individually or in combination. For example, this reduces the possibility that the examination of the eye may not proceed properly due to the subject operating the ophthalmic device or changing its settings, thereby allowing the examination to proceed appropriately.

[0027] This disclosure is not limited to the apparatus described in this embodiment. For example, terminal control software (program) that performs the functions of the above embodiment can be supplied to the apparatus or system via a network or various storage media, and the control device (e.g., CPU) of the apparatus or system can read and execute the program.

[0028] <Examples> An embodiment of the ophthalmic device according to this embodiment will be described below. In the following description, an ophthalmic device will be described using an eye refractive power measuring device as an example.

[0029] <Device configuration> Figure 1 is an external view of the eye refractive power measuring device 1. The eye refractive power measuring device 1 comprises a base 2, a face support unit 3, a drive unit 4, a display unit 75, an operation unit 76, an announcement unit 89, a face imaging unit 90, and a measurement unit 100, etc. The face support unit 3 is fixed to the base 2 and supports the subject's face. The face support unit 3 comprises a forehead rest 3a, a chin rest 3b, a chin rest sensor 3c, a chin rest drive unit 3d, etc. The forehead rest 3a supports the subject's forehead. The chin rest 3b supports the subject's chin. The chin rest sensor 3c detects whether the chin is resting on the chin rest 3b. The chin rest drive unit 3d moves the chin rest 3b up and down to adjust its height. The drive unit 4 drives the measurement unit 100 in the XYZ directions relative to the base 2. The display unit 75 displays various information (for example, an image of the subject's face, an image of the anterior segment of the eye being examined, measurement results of the eye being examined, etc.). The operation unit 76 is used for various settings. In this embodiment, the display unit 75 with a touch panel also serves as the operation unit 76. The operation unit 76 may be any human interface such as a touch panel, joystick, mouse, keyboard, trackball, or buttons. The announcement unit 89 makes announcements to the subject or examiner. In this embodiment, the announcement unit 89 is an audio output unit such as a speaker. Of course, the announcement unit 89 may also be a display unit such as a monitor. The face imaging unit 90, for example, captures a photograph of the face of the eye being examined. The face imaging unit 90 captures a photograph of the face including at least one of the left or right eyes being examined. The measurement unit 100 houses the optical system described later.

[0030] Figure 2 is a schematic diagram of the optical system and control system of the refractive power measuring device 1. The measurement unit 100 includes a measuring optical system 200, a fixation target optical system 300, an indicator projection optical system 400, an observation optical system 500, a face illumination optical system 600, a face imaging optical system 700, etc. The measuring optical system 200 objectively measures the refractive power of the eye E under test (e.g., spherical power, cylindrical power, astigmatism axis angle, etc.). The fixation target optical system 300 presents a fixation target to the eye E under test. The indicator projection optical system 400 projects an alignment indicator onto the eye E under test. The observation optical system 500 images the anterior segment of the eye E under test. The face illumination optical system 600 illuminates the face of the subject. The face imaging optical system 700 images the face of the subject. A beam splitter 230 is positioned in front of the eye E under test. The beam splitter 230 directs the measurement beam from the fixation target optical system 300 to the eye under examination E. The beam splitter 230 also directs the reflected beam from the anterior segment of the eye under examination E to the observation optical system 500.

[0031] <Measurement optical system> The measuring optical system 200 has a light-emitting optical system 210 and a light-receiving optical system 220 in the transmission direction of the beam splitter 230. The light-emitting optical system 210 includes a light source 211, a relay lens 212, a hall mirror 213, a prism 214, an objective lens 216, etc. The light source 211 is positioned optically conjugate to the fundus of the eye. The aperture of the hall mirror 213 is positioned optically conjugate to the pupil. The prism 214 is positioned away from the position optically conjugate to the pupil, causing the light beam passing through the prism 214 to be eccentric with respect to the optical axis N1. The prism 214 is rotated around the optical axis N1 by a drive unit 215. Alternatively, a parallel plane plate may be placed diagonally on the optical axis N1 instead of the prism 214.

[0032] The light-receiving optical system 220 includes an objective lens 216, a prism 214, a hall mirror 213, a relay lens 221, a total internal reflection mirror 222, a light-receiving diaphragm 223, a collimator lens 224, a ring lens 225, an image sensor 226, and the like. In the light-receiving optical system 220, the objective lens 216, the prism 214, and the hall mirror 213 are shared with the light-emitting optical system 210. The light-receiving diaphragm 223 is positioned optically conjugate to the fundus. The ring lens 225 is positioned optically conjugate to the pupil. The image sensor 226 is positioned optically conjugate to the fundus.

[0033] In this configuration of the measurement optical system 200, the measurement light beam emitted from the light source 211 passes through the relay lens 212, the hall mirror 213, the prism 214, the objective lens 216, and the beam splitter 230, and is projected onto the fundus as a spot-shaped light beam. This forms a point light source image on the fundus. At this time, the prism 214 is rotated around the optical axis N1, and the pupil projection image (projected light beam on the pupil) at the aperture of the hall mirror 213 is rapidly eccentrically rotated. The reflected light beam, which is the measurement light beam reflected from the fundus, is reflected back to the hall mirror 213 via the beam splitter 230, the objective lens 216, and the prism 214. The reflected light beam is further reflected by the relay lens 221 and the total internal reflection mirror 222, and is focused at the position of the light receiving aperture 223, where it is imaged onto the image sensor 226 as a ring-shaped image (ring image) by the collimator lens 224 and the ring lens 225. The output signal from the image sensor 226 is input to the control unit 70, where the refractive power of the eye is calculated.

[0034] <Fixation target optical system> The fixation target optical system 300 includes a light source 301, a fixation target plate 302, a projection lens 303, a total internal reflection mirror 304, a half mirror 305, an objective lens 306, etc., in the reflection direction of the beam splitter 230. The fixation target plate 302 is illuminated by the light source 301, presenting the fixation target to the eye under examination E. The fixation target plate 302 is used to have the eye under examination E fixate on it and to measure its refractive power. The drive unit 307 can move the presentation position of the fixation target to the eye under examination E by moving the fixation target plate 302 in the direction of the optical axis N2. In addition, the drive unit 307 can create a haze over the eye under examination E by moving the light source 301 and the fixation target plate 302 in the direction of the optical axis N2.

[0035] The drive unit 307 may change the presentation position of the fixation target by moving the projection lens 303 in the direction of the optical axis N2 relative to the fixation target plate 302. Therefore, the drive unit 307 may add a cloud effect to the eye under examination E by moving the projection lens 303 in the direction of the optical axis N2 relative to the fixation target plate 302.

[0036] <Indicator projection optical system> The index projection optical system 400 comprises a first index projection optical system and a second index projection optical system. The first index projection optical system projects an alignment index at infinity onto the cornea of ​​the eye E under examination. The second index projection optical system projects an alignment index at a finite distance onto the cornea of ​​the eye E under examination.

[0037] The first indicator projection optical system includes point light sources 401a and 401b, collimator lenses 402a and 402b, etc. The point light sources 401a and 401b emit near-infrared light. The collimator lenses 402a and 402b convert the light beams emitted by the point light sources into parallel light beams (approximately parallel light beams). For example, multiple of these point light sources and collimator lenses are arranged at 45-degree intervals on concentric circles with respect to the optical axis N1, and are symmetrical on both sides of a vertical plane passing through the optical axis N1.

[0038] The second indicator projection optical system has point light sources 403a and 403b. Point light sources 403a and 403b emit near-infrared light. For example, multiple of these point light sources are arranged at a narrower angle than the point light source of the first indicator projection optical system, and symmetrically across a vertical plane passing through the optical axis. The second indicator projection optical system can also be used as an anterior segment illumination to illuminate the anterior segment of the eye E under examination, as an indicator for measuring the corneal shape of the eye E under examination, etc.

[0039] The index projection optical system 400 may be configured to project at least one of the following: a point-shaped index, a ring-shaped index (such as a Mayer ring), a line-shaped index, etc.

[0040] <Observation Optical System> The observation optical system 500 has an objective lens 306, a half mirror 305, an imaging lens 501, an image sensor 502, etc., in the reflection direction of the beam splitter 230. The image sensor 502 is in an optically conjugate positional relationship with the anterior segment of the eye E under examination and receives the reflected light beam from the anterior segment. This captures an image of the anterior segment of the eye E under examination (a frontal image of the anterior segment). A transillumination image, which is a type of anterior segment image, may also be captured. The output signal from the image sensor 502 is input to the control unit 70 and the display unit 75. The observation optical system 500 also serves as an optical system for detecting an alignment index image formed on the cornea of ​​the eye E under examination, and the control unit 70 detects the position of the alignment index image.

[0041] <Facial Illumination Optics> The face illumination optical system 600 includes an illumination light source 601, etc. The illumination light source 601 may be a light source with low directionality. The illumination light source 601 may also be a light source that emits infrared light.

[0042] <Facial imaging optics> The face imaging optical system 700 includes an imaging lens 701, an image sensor 702, and the like. The image sensor 702 receives reflected light from the face. This captures a face image that includes at least one of the left and right eyes of the eye being examined E. The output signal from the image sensor 702 is input to the control unit 70 and the display unit 75.

[0043] In this embodiment, the face imaging optical system 700 is equipped with a wide-angle lens as the imaging lens 701, allowing the subject's face to be captured with a wide field of view. For example, the field of view may be 87° or more. This makes it easier for both of the subject's eyes to be included in the face image. In this embodiment, a visible light cut filter may also be placed in the optical path of the face imaging optical system 700. This limits visible light noise when capturing the subject's face. Here, the reflected infrared light from the face is detected by the image sensor 702, but in this case, there is a possibility that infrared light noise may be incident. For this reason, the gain of the image sensor 702 may be adjusted to reduce the influence of infrared light noise.

[0044] <Department Head> The control unit 70 includes a CPU (processor), RAM, ROM, etc. The CPU controls the operation of each part of the eye refractive power measuring device 1. The RAM temporarily stores various types of information. The ROM stores various programs executed by the CPU. The control unit 70 may be composed of multiple control units (i.e., multiple processors).

[0045] The control unit 70 is electrically connected to the drive unit 4, the display unit 75 (operation unit 76), the non-volatile memory 72 (hereinafter referred to as memory 72), the announcement unit 89, etc. In addition, the control unit 70 is electrically connected to the light sources, image sensors, drive units, etc. of the measurement unit 100.

[0046] Memory 72 is a non-transient storage medium that can retain its contents even when the power supply is interrupted. For example, memory 72 can be a hard disk drive, flash ROM, USB memory, etc. Memory 72 may store the measurement results of the eye under examination E (for example, refractive power, eye position information, etc.).

[0047] <Control operation> The control operation of the refractive power measuring device 1, which has the above configuration, will now be explained.

[0048] In this embodiment, the eye refractive power measuring device 1 outputs voice announcements to guide the subject's examination and objectively measures the refractive power of the subject's eye by fully automating the process from alignment between the subject's eye E and the measuring unit 100 to acquiring measurement data.

[0049] Furthermore, the refractive power measuring device 1 in this embodiment can be configured to select either the first mode or the second mode as appropriate, depending on the subject's examination situation. For example, the first mode may be set when the examiner is present during the subject's examination and guides the subject to the device while interacting with them. Alternatively, the second mode may be set when the subject operates the device themselves and allows the examination to proceed automatically.

[0050] <When the examiner is present during the examination of the subject (Mode 1)> The following describes the case where the examiner is present during the examination of the subject (first mode). In this embodiment, when the eye refractive power measuring device 1 is started, the first mode is selected as the initial setting, and the voice announcement is set to the initial language such as the official language (in this case, "English"). For example, in the first mode, the examination screen is displayed on the display unit 75.

[0051] Figure 3 shows an example of an inspection screen displayed on the display unit. Figure 3(a) shows the state where the voice announcement language is set to the initial language. Figure 3(b) shows the state where the list of voice announcement languages ​​that can be set on the inspection screen is displayed. The inspection screen 800 has a mode switching button 802, a language call button 803, an announcement language screen 804, a setting change button 805, etc. The mode switching button 802 is a button for switching from the first mode to the second mode, which will be described later. The language call button 803 is a button for changing the voice announcement from the initial language to a desired language. For example, by operating the language call button 803, the announcement language screen 804 is called up. The announcement language screen 804 is a screen that displays a list of voice announcement languages ​​that the device can output. For example, by selecting a desired language from the list of languages, the voice announcement is set to the desired language. The setting change button 805 is a set of buttons for changing various settings. For example, buttons may be provided to change various settings, such as selecting the eye to be examined (measured eye) and changing the test items. The observation image 801 is at least one of the following: a facial image of the subject taken by the facial imaging unit 90, an anterior segment image taken by the measurement unit 100, etc. For example, the observation image 801 is captured and displayed when the subject places their face on the chin rest.

[0052] <Language settings for voice announcements> The examiner interacts with the subject and guides them to the device. If the examiner determines that the subject does not understand the initial language, they confirm the language the subject understands and then change the language of the voice announcement from the initial language to the desired language. For example, the examiner presses the language call button 803 on the examination screen 800. The control unit 70 displays the announcement language screen 804 based on the input signal from the language call button 803. For example, the examiner selects any language the subject understands from the list of languages ​​on the announcement language screen 804. The control unit 70 changes the voice announcement from the initial language to the desired language based on the input signal from the announcement language screen 804. As a result, the language of the voice announcement is changed to the desired language.

[0053] Once the control unit 70 has finished setting the language for the voice announcement, it closes the announcement language screen 804 and displays the selected language on the language call button 803. For example, in this embodiment, when "Japanese" is selected from the list of languages, "Japanese" is displayed on the language call button 803, and the voice announcement switches to Japanese.

[0054] The examiner changes the language of the voice announcement and, if necessary, changes various settings of the examination, then presses an examination start button (not shown) to begin the examination of the subject's eye. The control unit 70, in response to the input signal from the examination start button, causes the announcement unit 89 to output a Japanese voice announcement instructing the subject to rest their face on the chin rest. The subject rests their face on the chin rest in accordance with the voice announcement.

[0055] <Objective measurement> Based on the detection result of the chin rest sensor 3c provided on the chin rest 3b of the face support unit 3, the control unit 70 detects that the subject's face is placed on the chin rest 3b and outputs a Japanese voice announcement to the announcement unit 89 instructing the subject to fixate on the fixation target. The control unit 70 also turns on the light source 301 of the fixation target optical system 300, the light source of the indicator projection optical system 400, and the illumination light source 601 of the face illumination optical system 600. As a result, the subject's face is illuminated and an image of the subject's face is captured. The control unit 70 displays the face image as an observation image 801 on the display unit 75.

[0056] When the control unit 70 detects the eye under examination from the observation image 801 (face image), it moves the imaging unit 100 in the XYZ direction based on the three-dimensional position information of the eye under examination, completing the rough alignment of the imaging unit 100 with respect to the eye under examination. This allows an anterior segment image of the eye under examination E to be captured. The control unit 70 switches the observation image 801 from the face image to the anterior segment image and displays it on the display unit 75. Subsequently, when the control unit 300 detects the eye under examination from the observation image 801 (anterior segment image), it uses the alignment index image to move the imaging unit 100 in the XYZ direction, completing the fine alignment of the imaging unit 100 with respect to the eye under examination.

[0057] The control unit 70 controls the measurement optical system 200 based on an input signal indicating the completion of alignment of the eye under examination, irradiates the fundus of the eye under examination with measurement light, and measures the refractive power of the eye under examination based on the detection result of the measurement light reflected by the fundus. For example, the control unit 70 may identify the position of the ring image in each meridian direction and approximate it using the least squares method or the like, and determine the refractive power based on the approximated shape of the ring image. Once the measurement of one eye under examination is completed, the control unit 70 moves the measurement unit 100 to the other eye and performs alignment and refractive power measurement on that eye as well.

[0058] <Initialization> When the measurement of the refractive power of the eye under examination is complete, the control unit 70 outputs the measurement results (measurement data). For example, the control unit 70 may display the measurement results on the examination screen 800, print them out, or output them to an external device wirelessly or via a wired connection. The examiner confirms the measurement results of the eye under examination E and presses an examination end button (not shown) to end the examination of the eye under examination. In response to the input signal from the examination end button, the control unit 70 clears the measurement results displayed on the examination screen 800. Also, in response to the input signal from the examination end button, the control unit 70 returns the language of the voice announcement to the initial language (i.e., from Japanese to English in this embodiment) and displays the examination screen 800 (see Figure 3a) with the voice announcement set to the initial language on the display unit 75. This completes the initialization of the refractive power measuring device 1.

[0059] For example, when the first mode is set, for subjects who can understand the initial language of the voice announcement, there is no need to set (change) the language of the voice announcement, and the examination can be conducted smoothly. For subjects who cannot understand the initial language of the voice announcement, the announcement language screen 804 can be called up using the language call button 803 as appropriate, and the voice announcement can be changed to the desired language from the list of languages ​​on the announcement language screen 804, making it easy to set an announcement language suitable for the subject. Furthermore, when the voice announcement is changed from the initial language to a different language, the voice announcement will be set back to the initial language after the examination is completed, reducing the effort required to readjust the language of the voice announcement. In addition, the time required for such operations is reduced.

[0060] <When the subject conducts the examination themselves (Mode 2)> The following describes the case where the subject conducts the examination themselves (second mode). In this embodiment, the first mode is selected as the initial setting when the eye refractive power measuring device 1 is started, but the setting can be switched from the first mode to the second mode by pressing the mode switching button 802 on the examination screen 800 (see Figure 3(a)). In the second mode, the subject is asked to select a language they understand each time the subject changes, so it is not necessary for the voice announcement to be set to the initial language such as the official language.

[0061] For example, when the examiner is examining various subjects with different native languages, they may press the mode switching button 802 on the examination screen 800 to set a second mode. Based on the input signal from the mode switching button 802, the control unit 70 changes the display on the display unit 75 from the examination screen 800 to the language selection guidance screen. For example, the language selection guidance screen is a screen that allows the subject to select the language of the voice announcement themselves.

[0062] Figure 4 shows an example of a language selection guidance screen displayed on the display unit. For example, the language selection guidance screen 810 includes an operation instruction screen 811, a language selection button 812, a mode switching button 813, etc. The operation instruction screen 811 is a screen that shows operation instructions (guidance information) for the subject to select the language of the voice announcement. For example, the operation instructions may be text written in each language that the device can output, indicating that the desired language should be selected. The language selection button 812 is a button for the subject to select the desired language of the voice announcement. For example, the language selection button 812 may be a list of multiple buttons corresponding to the text in each language in the operation instructions. The mode switching button 813 is a button for switching from the second mode to the first mode described above. Note that the mode switching button 813 may be locked to prevent operation by the subject.

[0063] <Language settings for voice announcements> For example, the subject sits in front of the refractive power measuring device 1, following the examiner's instructions, and checks the display unit 75 which shows the language selection guidance screen 810. For example, the control unit 70 keeps the language selection guidance screen 810 displayed as a standby screen until an input signal is detected from the language selection button 812. The examiner selects the language selection button 812 corresponding to the desired language that the subject understands, following the operation instructions on the operation instruction screen 811. The control unit 70 sets the language of the voice announcement based on the input signal from the language selection button 812. For example, if the subject checks the operation instruction screen 811 and understands the Japanese text instructing them to select the desired language, the "1. Japanese" button is pressed from the list of language selection buttons 812. The control unit 70 sets the language of the voice announcement to Japanese based on the input signal from the language selection button 812.

[0064] Once the language setting for the voice announcement is complete, the control unit 70 switches the display on the display unit 75 from the language selection guidance screen 810 to the examination screen 800 and automatically starts the examination. For example, the control unit 70 outputs a Japanese voice announcement to the announcement unit 89 instructing the subject to place their face on the chin rest. The subject places their face on the chin rest in accordance with the voice announcement.

[0065] <Objective measurement> For example, when the control unit 70 detects that the subject's face is placed on the chin rest 3b, it displays the observation image 801 on the examination screen 800 and performs measurements of the alignment and refractive power of the subject's eye. This is the same as in the first mode, so no further explanation is provided. Note that the selection of the eye to be measured and the examination items (various settings for the examination) in objective measurements may be set in advance when the examiner sets the second mode.

[0066] Here, for example, if the subject accidentally operates any of the buttons on the examination screen 800, the device may malfunction, the device settings may be changed, or the measurement of refractive power may stop. For this reason, the control unit 70 may, for example, detect the input signal from the language selection button 812, set the language for the announcement, and then disable the input of operation signals from the examination screen 800 (display unit 75). In other words, it may prohibit the change of settings or the execution of actions based on operation signals. Alternatively, for example, the control unit 70 may overlay a message screen (guidance or instructions, etc.) such as "Measurement in progress" or "Do not touch the screen" on the examination screen 800. Of course, the device may also announce via voice announcement that the input of operation signals to the examination screen 800 is disabled. This reduces the possibility of the device malfunctioning, the device settings being changed, or the measurement of refractive power stopping, allowing the examination to be conducted smoothly.

[0067] <Initialization> Once the measurement of the refractive power of the eye being examined is complete, the control unit 70 outputs the test results (measurement data). Furthermore, after a certain period of time has elapsed since the end of the measurement, the control unit 70 displays the language selection guidance screen 810 again on the display unit 75. At this time, the control unit 70 releases the deactivation of the operation signal input on the display unit 75. This completes the initialization of the refractive power measuring device 1.

[0068] When the next subject takes over, the next subject selects the desired language for the voice announcement from the language selection button 812. For example, the "3. Italiano (Italian)" button is pressed from the list of language selection buttons 812. Based on the input signal from the language selection button 812, the control unit 70 changes the language setting of the voice announcement from Japanese, which was selected by the previous subject, to Italian, which was selected by the next subject. Of course, the control unit 70 may also clear the language setting selected by the previous subject before displaying the language selection guidance screen 810 on the display unit 75.

[0069] For example, when the second mode is set, the subject can easily set the language of the voice announcements they can understand by checking the operation instruction screen 811 of the language selection guidance screen 810. Also, when the examination of the previous subject is completed and it is time to move on to the next subject, the language selection guidance screen 810 is displayed, so the examiner does not need to change the language of the voice announcements, and it is possible to efficiently handle situations such as when the subject's native language is different.

[0070] As explained above, for example, the ophthalmic device of this embodiment displays a first language setting screen (e.g., a language selection guidance screen 810) for setting the announcement language, which is different from the condition setting screen for setting the examination conditions of the eye under examination. Based on the operation signal from the operation means for selecting the announcement language, the announcement is output from the notification means in the selected language, and the examination of the eye under examination proceeds. The first language setting screen is a screen on which any language can be selected from a list of multiple languages, and the first language setting screen is displayed as the initial screen each time the examination of the eye under examination is completed. For example, in an ophthalmic device where the announcement language is set to a predetermined language (for example, an official language), if the subject does not understand the announcement language, it is necessary to change the announcement language setting and perform the examination. Furthermore, after the examination is completed, it is necessary to change the changed announcement language setting back to the original language (official language). However, in the ophthalmic device of this embodiment, the first language setting screen is displayed each time the examination of the eye under examination is completed, and the desired language can be selected each time the subject changes before starting the examination, making it easy to set an announcement language suitable for the subject.

[0071] Furthermore, in the ophthalmic device of this embodiment, for example, the first language setting screen includes guidance information (e.g., operation instruction screen 811) for guiding the selection of the announcement language and setting buttons (e.g., language selection button 812) that support multiple languages. Based on the operation signal from the setting button, the announcement is output in the selected language, and the examination of the eye under test proceeds. This allows, for example, the announcement language suitable for the subject to be easily set using the guidance information, thus enabling the examination to proceed smoothly.

[0072] Furthermore, the ophthalmic device of this embodiment includes, for example, a first mode in which the condition setting screen is displayed as the initial screen each time the examination of an eye is completed, and a second mode in which the first language setting screen is displayed as the initial screen each time the examination of an eye is completed. Depending on the selected mode, either the condition setting screen or the first language setting screen is displayed. For example, in the first mode, if the subject does not understand the language of the announcement, it is possible to change it as appropriate from a predetermined language to the language desired by the subject. For example, in the second mode, each time the subject changes, the language of the announcement can be selected in advance to match the language used by the subject. In this way, the ophthalmic device of this embodiment allows the subject to easily select the language of the announcement desired by the subject by switching modes according to various examination situations, thus enabling smooth examinations.

[0073] Furthermore, in the ophthalmic device of this embodiment, for example, the first mode is a mode for the examiner to select the language of the announcements, and the second mode is a mode for the patient to select the language of the announcements. For example, when the examiner is conducting the examination while interacting with the patient, the first mode may be selected, and the language may be changed if the patient does not understand the pre-set announcement language. Alternatively, for example, when the patient is conducting the examination themselves, the second mode may be selected, and the patient may change the announcement language to one that they can understand and proceed with the examination according to the changed voice announcement. This allows for the mode to be switched appropriately depending on whether or not an examiner is present, enabling the examination to proceed smoothly.

[0074] Furthermore, in the ophthalmic device of this embodiment, for example, the condition setting screen is an examination screen (e.g., examination screen 800) that includes at least an observation image of the eye under examination and a call button to call up a second language setting screen (e.g., announcement language screen 804) for setting the language of announcements. For example, while setting the examination conditions on the examination screen, if the subject does not understand the pre-set announcement language, the examiner can easily set a language suitable for the subject by pressing the call button.

[0075] Furthermore, for example, the ophthalmic device of this embodiment sets the announcement language to a pre-set initial language each time the examination of the patient's eye is completed. For example, if the patient does not understand the initial announcement language (for example, the official language) and changes the announcement language setting, it is necessary to change it back to the original language (official language) after the examination is completed, which creates extra work. However, with the ophthalmic device of this embodiment, the announcement is set to the initial language each time the examination of the patient's eye is completed, thus reducing the effort required to change the announcement language setting back to the initial language each time it is changed. In addition, the time required for such operations is reduced.

[0076] Furthermore, for example, in this embodiment, when the second mode is set, the ophthalmic device changes its operation control to prohibit operation of the ophthalmic device after the announcement language is selected. For example, if the subject operates the ophthalmic device or changes its settings, the examination of the subject's eye may not proceed properly. However, by changing the operation control to prohibit operation according to the setting of the second mode, the examination of the subject's eye can be carried out properly.

[0077] <Example of transformation> In this embodiment, the configuration in which the inspection screen 800 and the language selection guidance screen 810 (see Figure 4) are displayed on the same display unit 75 has been described as an example, but the system is not limited to this. For example, the inspection screen 800 and the language selection guidance screen 810 may be displayed on different display units. For example, a first display unit (display unit 75) and a second display unit different from the first display unit may be provided, and the language selection guidance screen 810 may be displayed on the second display unit.

[0078] Furthermore, in this embodiment, we have described an example configuration in which the subject changes the language of the voice announcements used to guide the examination of the subject's eye E by operating the language selection button 812 on the language selection guidance screen 810, but we are not limited to this. For example, if instructions or guidance for the subject are displayed as messages on the display unit 75, the system may be configured so that the subject changes the language of such messages by operating the language selection button 812.

[0079] Furthermore, in this embodiment, the configuration was described using a different screen for the announcement language screen 804, which displays a list of voice announcement languages ​​in the first mode, and the language selection guidance screen 810, which displays a list of voice announcement languages ​​in the second mode. However, the embodiment is not limited to this configuration. For example, the announcement language screen 804 in the first mode may be the same screen as the language selection guidance screen 810 in the second mode. In this case, when the examiner presses the language call button 803 in the first mode, the control unit 70 may display the language selection guidance screen 810 on the display unit 75 based on the input signal from the language call button 803. As a result, the language selection button 812 is displayed along with the operation instructions on the operation instructions screen 811, so the examiner can use the language selection button 812 to change the voice announcement from the initial language to the desired language. When the setting of the voice announcement language is complete, the control unit 70 closes the language selection guidance screen 810 and displays the inspection screen 800 on the display unit 75. For example, even when the first mode is set, the language selection guidance screen 810 can be used to change the language of the voice announcement, making it easy to set a language of voice announcement that is suitable for the subject.

[0080] Furthermore, in this embodiment, the case in which the desired language is selected by operating the language call button 803 on the examination screen 800 (see Figure 3(a)) before starting the examination of the eye E in the first mode was described as an example, but it is not limited to this. For example, the language call button 803 may always be displayed on the examination screen 800, and it is possible to operate the language call button 803 even after the examination of the eye E has started. For this reason, the examiner may change the language of the voice announcement while checking the situation, such as whether the examination of the eye E is progressing.

[0081] Furthermore, in this embodiment, in the second mode, an operation explanation screen 811 is displayed on the language selection guidance screen 810 (see Figure 4) to allow the subject to select their desired language, but the embodiment is not limited to this. For example, the operation explanation screen 811 may be displayed on the language selection guidance screen 810, and the contents of the operation explanation screen 811 may be output as an audio announcement to the announcement unit 89. For example, an audio announcement such as "On this screen, select the audio guidance language. Please press the button for the desired language." or "On this screen, select the audio guidance language. The currently selected language is number 1." may be output sequentially in each language.

[0082] Furthermore, in this embodiment, in the second mode, the configuration was described as one in which the operation instructions are displayed in text in each language as the operation instructions screen 811 of the language selection guidance screen 810 (see Figure 4), but the embodiment is not limited to this. For example, the operation instructions on the operation instructions screen 811 may be indicated by icons or the like that can guide the subject to select the language of the announcement.

[0083] Furthermore, in this embodiment, the switching between the first mode and the second mode was described using a configuration in which the mode switching button 813 provided on the examination screen 800 and the language selection guidance screen 810 is performed by operating them, but the system is not limited to this configuration. For example, the switching between the first mode and the second mode may be performed by operating a button or icon placed on the home screen that awaits the examiner's input.

[0084] Figure 5 shows an example of the home screen displayed on the display unit 75 of the eye refractive power measuring device 1. In this embodiment, the home screen 900 may be displayed on the display unit 75 when the eye refractive power measuring device 1 is started up. For example, the home screen 900 is the basic screen for screen transitions. For example, the home screen 900 is the screen before transitioning to another screen. For example, the home screen 900 can transition to various screens.

[0085] The home screen 900 displays an ID input button 910, a measurement eye selection button 911, a mode selection button 914, a screen transition button 912, etc. The ID input button 910 is for entering an ID. When the ID input button 910 is pressed, the control unit 70 displays an input screen (for example, a keyboard screen) for entering the ID. The measurement eye selection button 911 is for selecting binocular or monocular measurement. The mode selection button 914 is for setting the first mode or the second mode. When the mode selection button 914 is pressed, the control unit 70 displays an input screen for selecting one of the modes. Of course, the mode selection button 914 can also be selected directly on the home screen 900, like the measurement eye selection button 911. The screen transition button 912 is for transitioning the home screen 900 to a screen corresponding to the first mode or the second mode.

[0086] The examiner sets the examination conditions for the eye E being examined by operating various buttons and presses the screen transition button 912. Based on the input signal from the screen transition button 912, the control unit 70 transitions to the examination screen 800 if the first mode is set, and to the language selection guidance screen 810 if the second mode is set. In the eye refractive power measuring device 1 of this embodiment, the first mode and the second mode may be selected via the home screen 900 in this way. To switch between each mode, the home screen 900 can be called up from the examination screen 800 or the language selection guidance screen 810.

[0087] In this embodiment, in the first mode, an inspection screen 800 having an observation image 801 and a language call button 803 is displayed on the display unit 75 as a screen on which inspection conditions, including the language of the voice announcement, can be set. However, the embodiment is not limited to this. For example, in the first mode, the aforementioned home screen 900 may be displayed on the display unit 75 as a screen on which inspection conditions can be set. In this case, a language selection button 913 may be displayed on the home screen 900, and by operating the language selection button 913, a list of voice announcement languages ​​that the device can output may be displayed.
