The diopter check device to which the present application relates will be described below with reference to fig. 1 to 4.
It should be noted that figures 1-4 are exemplary only and are not intended to be limiting as to the specific shape and configuration of the diopter inspection device. As shown in fig. 1 to 4, the diopter check device 100 is a portable autonomous check device which can perform diopter check by holding it in hand or placing it on a table or the like. The user can independently accomplish diopter inspection process through this diopter check out test set 100, need not visual chart case beyond 5 meters in the traditional inspection, also need not special doctor, nurse to can overcome the place restriction of traditional diopter inspection, and can reduce the input of manpower.
As shown in fig. 1-4, diopter check apparatus 100 may include an eyepiece 110, a barrel 120, an objective lens 130, a sighting mark display screen 140, and a diopter adjustment device 150. In some embodiments, the diopter check apparatus 100 may further include an information display screen 160, an information input device 170, and a astigmatism adjustment device 180. In some embodiments, diopter check device 100 may further include any combination of one or more of mirror 125, storage card slot 191, USB ports 192 and 193, charging system 194, and accessory device 195 (including a charger, data line, etc.). Specifically, the optotype display screen 140 may be used to display optotypes; an eyepiece 110 and an objective lens 130 are attached to the eye tube 120, and a user (examinee) can observe the optotype on the optotype display screen 140 through the eyepiece 110 and the objective lens 130. The diopter adjustment device 150 may adjust the diopter of the inspection apparatus 100 by adjusting the eyepiece 110 and/or the objective lens 130. In the embodiment of the present application, the diopter of the inspection apparatus 100 may represent the strength of the diopter action of the combination of the eyepiece 110 and the objective lens 130 on the human eye, which may be obtained by a comprehensive calculation based on the diopter of the eyepiece 110, the diopter of the objective lens 130, and the distance between the eyepiece 110 and the objective lens 130.
In some embodiments, eyepiece 110 may be a plano-optic lens or a concave lens with some optical power. For example, eyepiece 110 may be a lens with diopters of-10D to 0 (e.g., -8D, -6D, -4D, -2D, etc.). In some embodiments, eyepiece 110 may be a single lens that is fixed in diopter, or may include a set of lenses (e.g., a lens disk) that are adjustable in diopter. For example, the eyepiece 110 may be a lens disk composed of at least two lenses having different diopters. In some embodiments, the initial lens of eyepiece 110 may be a plano lens. In some embodiments, the eyepiece 110 can be adjusted by the eyepiece adjustment device 151 to change the diopter. In some embodiments, eyepiece 110 may be square in shape (as shown in fig. 1), circular in shape (as shown in fig. 4), or the like. Preferably, eyepiece 110 is circular in shape.
The view tube 120 may be used to connect the eyepiece 110, the objective lens 130, and the optotype display screen 140, so that the three are arranged in sequence. In some embodiments, objective 130 may be movable relative to view tube 120. In some embodiments, the viewing cylinder 112 may be made of a material that is opaque to light, so as to prevent interference from external light. Specifically, the material of the view tube 112 may include metal, plastic, ceramic, composite material, and the like.
The objective lens 130 may be a convex lens. For example, the objective lens 130 may be a convex lens of +3D to +10D (e.g., +5D, +6D, +8D, etc.). Diopter of the diopter check device 100 can be made different by using objective lenses 130 of different powers. In an embodiment of the present application, the objective lens 130 is movable within the barrel 120, and the diopter of the diopter check device 100 can be adjusted by moving the objective lens 130. In some embodiments, the distance between the objective 130 and the target display screen 140 may always be greater than one focal length of the objective 130, in which case the target on the target display screen 140 will be an inverted real image under the action of the objective 130. In some embodiments, the objective 130 may be moved between one focal length and two focal lengths from the target display screen 140. In some embodiments, the objective lens 130 may also be moved more than twice the focal length away from the optotype display screen 140. In order to allow the objective lens 130 to have a sufficient moving space, the length of the view tube 120 needs to be at least two times longer than the focal length of the objective lens 130, for example, the length of the view tube 120 may be set to 4 to 5 times the focal length of the objective lens 130. Meanwhile, in order to make the diopter checking apparatus 100 small and portable, the length of the barrel 120 should not be too long, and the length of the barrel may be set to be less than 1 meter. In one embodiment, the objective lens 130 may have a diopter of +5D (i.e., a focal length of 20cm), and the length of the barrel 120 may be set to about 85 cm.
The visual target display 140 may be used to display visual target, color chart, astigmatism map, etc. in some embodiments, the visual target may include E, C, J, etc. shaped visual target or any combination thereof, for example, the visual target may be an E-shaped visual target on an international standard visual target, the visual target display 140 may be used to display visual targets of different sizes and/or opening directions, depending on whether the visual target is seen by the user at the time of detection, the visual targets of different sizes may correspond to 0.1-2.0 (or 4.0-5.3), respectively, in some embodiments, the visual target display 140 may only display one visual target at a time so that the user can recognize the one visual target, in some alternative embodiments, two or more visual targets may be displayed on the visual target display 140 each time, for example, the visual target display 140 may display 4 visual targets at a time, the 4 visual targets may be arranged symmetrically with respect to each other, up and down, left and right, and up, and down, if the visual target display is a visual target display of a high visual target brightness, a visual target, a high visual target visual display, a visual target visual display 140, a visual target visual display, a visual target visual display, a visual target visual.
In some embodiments, the centers of eyepiece 110, objective lens 130, and optotype display screen 140 may be located on a straight line. In some embodiments, as shown in fig. 2-3, a pair of reflectors 125 may be further included in the viewing cylinder 120, and the light rays of the optotype are directed to the eyepiece by reflection of the reflectors 125. By providing the pair of mirrors 125, the light transmission distance between the eyepiece 110 and the objective lens 130 can be increased without increasing the length of the barrel by using the principle of light translation (periscope principle), thereby contributing to reduction in size of the diopter inspection apparatus 100.
The diopter adjustment device 150 may adjust the diopter of the inspection apparatus 100 by adjusting the eyepiece and/or the objective lens. In some embodiments, the diopter adjustment device 150 may include an eyepiece adjustment device 151, an objective lens adjustment device 152, a manipulation device 153, a controller 154, and the like, or any combination thereof.
The eyepiece adjusting device 151 can adjust the diopter of the eyepiece 110 by adjusting the lens of the eyepiece 110. For example, the eyepiece adjustment device 151 may be a screw knob or dial or the like that switches the lens disk to a different lens by rotating the pointer to a different diopter label. In some embodiments, the user can change the diopter of eyepiece 110 by manually adjusting eyepiece adjustment device 151. In some embodiments, eyepiece adjustment device 151 may establish communication with controller 154, and the eyepiece adjustment device may automatically adjust the diopter of eyepiece 110 under the control of controller 154.
The objective lens adjusting means 152 may adjust the diopter of the diopter check device 100 by adjusting the distance of the objective lens 130 with respect to the optotype display screen 140. In some embodiments, the user may adjust the position of the objective 130 by manually adjusting the objective adjustment device. For example, the objective lens adjusting means 152 may be a focus screw knob, and the user may adjust the distance of the objective lens 130 with respect to the optotype display screen 140 by manually screwing the focus screw knob to a different numerical scale line. In some embodiments, objective lens adjustment device 152 may be in communication with controller 154, and objective lens adjustment device 152 may automatically adjust the position of objective lens 130 under the control of controller 154. For example, the objective lens adjusting device 152 may include a motor and a transmission mechanism, and the controller 154 may control the motor to rotate, and the motor may further move the objective lens 130 through the transmission mechanism such as a wire transmission, a gear transmission, and the like. In some embodiments, the controller 154 may control the moving speed (e.g., 0.1mm/s, 0.5mm/s, 1mm/s, 3mm/s, etc.), the moving range (e.g., 15cm, 20cm, etc.), the distance of each movement, and/or the moving direction (e.g., a direction away from and a direction closer to the target display screen), etc. of the objective 130 through the objective adjustment device 152.
The manipulation device 153 may be used to obtain feedback information of the user. The control device 153 may have a signal connection to the controller 154. In some embodiments, the manipulation device 153 may include a manipulation handle, a manipulation button, a voice recognition device, and the like, or any combination thereof. For example, the control device 153 may be a control handle/control button, and the user may select and confirm the current opening direction of the sighting target through the control handle/control button. For another example, the user may directly speak the current optotype opening direction to be recognized by the voice recognition apparatus. In some embodiments, the user's feedback information may include the user's feedback on being able to see the clear optotype. For example, when the diopter scale of the diopter check device 100 is changed (e.g., the objective lens 130 is moved) to the point where the user can see the clear icon, the user can control the diopter scale stop change (e.g., the objective lens 130 stops moving) by manipulating the button; or the user may say "stop" to control the diopter stop change by the voice recognition means. For another example, when the objective lens 130 moves to a position beyond "see-through", the user may push the corresponding control button for moving the objective lens 130 back, or directly speak a command corresponding to moving the objective lens 130 back, so as to move the objective lens 130 back. In some embodiments, the user may select or simulate a current color vision check indicator (e.g., numbers, characters, words, letters, graphics, etc.) by manipulating the handle, or the user may speak the color vision check indicator directly for recognition by the speech recognition device. In some embodiments, the user's feedback information may also include user feedback on the unobtrusive optotype. For example, the user's feedback of the invisible visual target may include a user's misjudgment of the opening direction of the visual target, a user's failure to respond to the visual target within a preset time threshold, and the like. In some embodiments, the user's feedback information may also include user feedback on recognizable color vision check marks and user feedback on unrecognizable color vision check marks. The user's feedback of the recognizable color vision test identifier may include the user recognizing the color vision test identifier within a predetermined time threshold, and the user's feedback of the unrecognizable color vision test identifier may include the user misrecognizing the color vision test identifier within the predetermined time threshold, the user not responding to the color vision test identifier within the predetermined time threshold, and the like. The control device 153 may have a signal connection with the controller 154, so that feedback information from the user may be transmitted to the controller 154.
In the embodiment of the present application, as shown in fig. 1-3, the manipulation device 153 may be a trigger-like manipulation button. By designing the manipulation button in the shape of a trigger, the manipulation by a user (examinee) can be facilitated. For example, when a user holds diopter inspection device 100 for inspection, the trigger can just be "pulled" with a finger. In some embodiments, the objective 130 can be moved from far (the distance of the objective relative to the eyepiece) to near, and when the user can see the eye mark clearly, the user can stop the movement of the objective 130 by "pulling" the trigger, and the diopter of the inspection device 100 is the diopter of the user corresponding to the eye to be inspected. In this embodiment, the examinee only needs to perform one operation (i.e., "pull" the trigger), which is simple and easy to use. In some embodiments, a trigger-like manipulation button may also be jogged up, down, left, and right. For example, a manipulation button like a trigger may be jogged left and right, and a user may dial the trigger left and right to autonomously control the movement of the objective lens 130.
The controller 154 may be used to execute the instructions of the present application. In particular, the controller 154 may implement methods, procedures, objects, components, data structures, procedures, modules, and functions that perform the particular functions described herein. For example, the controller 154 may be configured to control the eyepiece 110 (e.g., control the eyepiece to switch lenses) and/or the objective 130 (e.g., control the objective movement) to adjust the diopter of the inspection apparatus 100 based on user feedback information obtained by the manipulation device 153. In some embodiments, when the user feedback information indicates that the user can see the eye mark clearly, the controller 154 may stop controlling the eyepiece adjusting device 151 and/or the objective lens adjusting device 152 to adjust the eyepiece 110 and/or the objective lens 130, and calculate the diopter scale of the diopter scale checking apparatus 100 based on the parameter information (such as the diopter scale of the eyepiece 110 and the objective lens 130, the distance between the eyepiece 110 and the objective lens 130, and the like) of the diopter scale checking apparatus 100, where the diopter scale is the diopter scale of the user's eye. In some embodiments, when the user feedback is that the user is unable to see the legible target (or no feedback is obtained from the user that the user is able to see the legible target), the controller 154 may control the eyepiece adjusting device 151 to switch the lens of the eyepiece 110 and/or control the objective lens adjusting device 152 to move the position of the objective lens 130 until the manipulation device 153 obtains feedback from the user that the user is able to see the legible target.
In some embodiments, controller 154 may send adjustment instructions and/or data to eyepiece adjustment device 151 and objective adjustment device 152, respectively. For example, the controller 154 may control the objective lens adjusting device 152 to adjust the objective lens 130, and then control the eyepiece lens adjusting device 151 to adjust the eyepiece lens 110. For another example, the controller 154 may control the eyepiece adjusting device 151 to adjust the eyepiece 110 first, and then control the objective lens adjusting device 152 to adjust the objective lens 130. In some embodiments, controller 154 may also control eyepiece adjustment device 151 and objective adjustment device 152 to simultaneously adjust eyepiece 110 and objective 130. In some embodiments, the controller 154 may send parameters (e.g., a moving speed, a moving range, a distance per movement, a moving direction, etc.) and instructions (e.g., a start movement instruction, a stop movement instruction, etc.) associated with the movement of the objective lens 130 to the objective lens adjustment device 152 to cause the objective lens adjustment device 152 to control the movement of the objective lens 130. In some embodiments, controller 154 may send parameters associated with eyepiece adjustment device 151 (e.g., diopter of eyepiece 110) and instructions (e.g., selection instructions, switching instructions, etc.) to eyepiece adjustment device 151 to cause eyepiece adjustment device 151 to select the desired eyepiece 110. In some embodiments, controller 154 may also be used to control optotype display screen 140. For example, the controller 154 may control the optotype display screen 140 to change the opening direction of the optotype periodically (e.g., 3 seconds, 5 seconds, etc.). For another example, the controller 154 may control the optotype display screen to display a color vision test mark, an astigmatism map, and the like. In some embodiments, the controller 154 may include at least one hardware processor, such as a microcontroller, microprocessor, Reduced Instruction Set Computer (RISC), Application Specific Integrated Circuit (ASIC), application specific instruction set processor (ASIP), Central Processing Unit (CPU), Graphics Processing Unit (GPU), Physical Processing Unit (PPU), microcontroller unit, Digital Signal Processor (DSP), Field Programmable Gate Array (FPGA), high order RISC machine (ARM), Programmable Logic Device (PLD), any circuit or processor capable of performing at least one function, or the like, or any combination thereof.

For example, the optotype display screen 140 may be provided as a movable screen, and when performing a visual acuity test, the optotype display screen 140 may be moved into a viewing tube to display optotypes; before or after the visual acuity test, the sighting target display screen 140 can be moved out of the visual cylinder to be used as an information display screen. In some embodiments, the information display screen 160 has a signal connection with the controller 154. The controller 154 may control the content displayed on the information display screen 160.
The information input device 170 may be used to input user information and/or examination eye information. In some embodiments, information input device 170 may be a stand-alone key. For example, as shown in fig. 1 and 4, the information input device 170 may include a transmission key 171, an on-off key 172, a reset key 173, a function key 174, and the like. Specifically, the transmission key 171 may be used for the diopter check device 100 to transmit a signal to the outside, and for example, the controller 154 may transmit the diopter check result to a server, a terminal, or the like through the transmission key 171. The switch keys 172 may be used to turn the diopter check device 100 on and off. The reset key 173 may be used to return various types of parameters and/or settings of the diopter check device to the original parameters and/or settings, or preset parameters and/or settings. For example, when a user has finished examining one eye, the examination device may be reset via reset key 173 to examine the other eye of the user. For another example, when a user finishes the examination, the reset key 173 may reset the examination device for the next user to perform the examination. The function keys 174 can be used for selection, determination, implementation, and the like of functions such as diopter examination, color vision examination, astigmatism examination, eye disease examination, and the like. It is noted that the number, location, shape, function, etc. of the keys 171 and 174 shown in fig. 1 and 4 are for illustrative purposes and do not constitute any limitation of the present application. For example, the function keys 174 may also include a separate diopter check key, a color vision check key, and the like. For another example, the information input device 170 may be disposed below and/or above the information display screen 160. In some embodiments, the information input device 170 may also be touch screen keys on the information display screen 160, a voice input device, or any combination thereof. In some embodiments, the information input device 170 may input the user's name, gender, age, identification number, certificate, affiliated entity, social identity, medical history, and the like, or any combination thereof. For example, in a student's visual acuity testing activity at a school organization, the information input device 170 may input the name, gender, age, school number, school of the student, grade, class, etc., or any combination thereof. In some embodiments, the information input device 170 may also input examination eye information. For example, the user may input whether the current eye to be checked is the left eye or the right eye through the information input device 170. In some embodiments, examining the eye information may further include examining an initial diopter of the eye. The initial diopter of the inspection eye may be the diopter measured by the user at the previous diopter inspection. When the user inputs the initial diopter strength of the inspection eye, the controller 140 may adjust the inspection apparatus 100 to an appropriate diopter strength according to the initial diopter strength to start the diopter strength inspection process, thereby contributing to an improvement in the diopter strength inspection efficiency. In some embodiments, the eye information may also include the wearing state of the user, e.g., whether to wear glasses, when to wear glasses, the degree of wear, etc.
The astigmatism adjustment means 180 may perform astigmatism check by adjusting an astigmatism mirror. The astigmatic lens may be a set of lenses (e.g., a lens disk) for adjusting the astigmatism of the diopter check device 100. For example, the astigmatic lenses may be 0-4D diopters of astigmatic lenses. In some embodiments, an astigmatic lens may be mounted adjacent to eyepiece 110. In some embodiments, the astigmatic lens may be mounted in the same lens disk as the lens of eyepiece 110. Accordingly, the astigmatism adjustment device 180 may be independent of the eyepiece adjustment device 151, or may be integrated in the eyepiece adjustment device 151. Similar to the eyepiece adjusting device 151, the cylindrical adjustment device 180 can be a screw knob or dial or the like that can be switched to a different lens by turning the pointer to a different cylindrical label. Alternatively, the astigmatism adjustment device 180 may establish communication with the controller 154, and the controller 154 may send adjustment instructions and/or data to the astigmatism adjustment device 180 based on its astigmatism mirror adjustment mechanism/program, so that the astigmatism adjustment device 180 performs a corresponding adjustment action (i.e., switches the lenses of the astigmatism mirror according to the instructions and/or data) to adjust the astigmatism of the astigmatism mirror. For example, the astigmatism adjustment device 180 may select a desired lens from a lens tray including at least two lenses and switch the current lens with the desired lens.
In some embodiments, the diopter check device 100 may also include a storage card slot 191, USB ports 192 and 193, a charging system 194, and accessory devices 195 (e.g., a charger, a data line, etc.). The storage card slot 191 and the USB ports 192 and 193 may be used to connect peripheral devices such as a USB disk, a computer, a mobile hard disk, a card reader, an iPad, a printer, a facsimile machine, a camera, a charger, a mobile phone, a mouse, a keyboard, etc., or any combination thereof. In some embodiments, a peripheral device such as described above may establish communication with diopter check device 100 through storage card slot 191 and USB ports 192 and 193. For example, the diopter check apparatus 100 may store the obtained diopter check data of the user in an inserted usb disk, or transmit it to a connected computer, or perform print processing by a connected printer. For another example, data, such as user information, may be input to the diopter check device 100 through a connected camera, keyboard, mouse, fingerprint recognizer, or the like. The charging system 194 may be used to provide electrical power support to the refraction examination device 100. The accessory device 195 may include a charger, a data line, etc. In some embodiments, the diopter check device 100 may further include a voice broadcasting device, and the voice broadcasting device may be used to send an action prompt to the examinee, broadcast a vision check result, and the like. For example, the voice broadcast device may prompt the examinee to input information, feed back visual target information, switch between left and right eyes, and the like by voice.
Figure 5 is an exemplary flow chart of a diopter check method according to some embodiments of the present application. As shown in fig. 5, the diopter check method may include:
In some embodiments, controller 154 (or diopter adjustment module 610) may send adjustment instructions and/or data to eyepiece adjustment device 151 and/or objective adjustment device 152, respectively, such that objective adjustment device 152 adjusts objective lens 130 and eyepiece adjustment device 151 adjusts eyepiece 110. In some embodiments, the user may also manually adjust eyepiece 110 and/or objective 130 to change the diopter of inspection device 100. For more details regarding the eyepiece 110, the objective lens 130, the eyepiece adjustment device 151, the objective lens adjustment device 152, the controller 154, diopter adjustment, etc., reference may be made to fig. 1-4 and its associated description.
In some embodiments, the manipulation device 153 may be used to obtain feedback information of the user. The information acquiring module 620 may receive the feedback information of the user acquired by the manipulation device 153. In some embodiments, the user feedback information may include user feedback on a legible target, user feedback on a direction of an opening of the target, user feedback on a non-legible target, user feedback on a recognizable color vision test mark, user feedback on a non-recognizable color vision test mark, and the like, or any combination thereof. For more details regarding the manipulation device 153 and obtaining user feedback information, reference may be made to fig. 1-4 and the associated description.
In step 530, the diopter of the user is determined according to the feedback information of the user. In particular, step 530 may be performed by diopter determination module 630.
In some embodiments, the controller 154 (or diopter determination module 630) may control the diopter adjustment means 150 to stop the adjustment operation according to the first feedback information of the user; and determines the diopter scale of the diopter check device 100 at the time when the diopter scale means stops the scale operation as the diopter scale of the user. Specifically, the first feedback information of the user may be feedback of the user on the visual target capable of being seen clearly. In some embodiments, the controller 154 may also display the diopter check result on the information display screen 160.
In some embodiments, the controller 154 (or diopter determination module 630) may control the diopter adjustment device 150 to stop the adjustment operation according to the first feedback information of the user. On this basis, the controller 154 (or diopter determination module 630) may control the optotype display screen to switch optotypes; and determines a further adjusting operation of the diopter adjusting means 150 according to the second feedback information of the user. Specifically, the controller 154 may switch the optotype on the optotype display screen to a smaller optotype (e.g., switch the optotype for vision 1.0 to the optotype for vision 1.2). The second feedback information of the user may include feedback of the user on the switched optotype direction. When the visual target direction fed back by the second feedback information of the user is correct, the visual target which can be 'seen' by the user for 1.2 of vision can be reflected, and then the visual target which can be 'seen' by the user for 1.0 of vision can be further confirmed; in this case, the controller 154 may determine the diopter scale (i.e., the visual target corresponding to 1.0 can be seen) of the diopter check apparatus 100 at the time when the diopter scale adjustment device stops the adjustment operation as the user's diopter scale (i.e., without further adjustment of the diopter scale adjustment device). When the direction of the visual target fed back by the second feedback information of the user is incorrect, the visual target of which the vision is 1.2 is not clearly seen by the user can be reflected, and then the fact that the user only sees the visual target of which the vision is 1.0 and does not see the visual target of which the vision is 1.0 clearly can be further inferred. In this case, controller 154 may control eyepiece adjustment device 151 and/or objective adjustment device 152 to continue adjusting eyepiece 110 and/or objective 130 to further determine the diopter of the eye of the user being examined.
In some embodiments, the diopter check device 100 may determine the user's color vision information and astigmatism information in addition to the user's diopter. Specifically, the controller 154 may control the diopter adjustment device 150 to stop the adjustment operation according to the first feedback information of the user, which indicates that the user can at least "see" the optotype. On the basis, the controller 154 can control the optotype display screen 140 to display the color vision inspection identifier; and determining color vision information of the user according to the third feedback information of the user. Specifically, the third feedback information of the user may include a recognition result of the color vision examination identifier by the user. The color vision information of the user may include color vision normality and color vision abnormality, wherein the color vision abnormality may further include color weakness including full color weakness and partial color weakness (e.g., red weakness, green weakness, blue-yellow weakness, etc.), color blindness including full color blindness and partial color blindness (e.g., red blindness, green blindness, blue-yellow blindness, etc.), and the like. In some embodiments, when the user can recognize the color vision check mark (e.g., the user recognizes the color vision check mark correctly), the controller 154 may determine that the color vision information of the user is normal; when the user cannot recognize the color vision test identification or recognizes an error (e.g., the user's recognition result of the color vision test representation is incorrect), the controller 154 may determine that the user's color vision information is abnormal. In some embodiments, based on determining that the color vision information of the user is color vision anomaly, the optotype display screen 140 may further display inspection identifiers for different color vision anomalies (e.g., color weakness and/or color blindness, or more specifically, full color blindness and partial color blindness (e.g., red blindness, green blindness, blue-yellow blindness, etc.), and/or full color weakness and partial color weakness (e.g., red weakness, green weakness, blue-yellow weakness, etc.)) to determine what color vision anomaly the user is. In some embodiments, if both the diopter scale and the color vision information of the user need to be determined, the user diopter scale may be determined first, and then the controller 154 may control the eyepiece adjusting device 151 and/or the objective lens adjusting device 152 to stop the adjusting operation and cause the optotype display screen 140 to display the color vision examination mark for color vision examination. In some embodiments, if only the color vision information of the user needs to be determined, the diopter of the diopter check device 100 does not need to be adjusted to the user's diopter precisely, but only needs to be adjusted roughly until the user can see the optotype on the optotype display screen 140, and then the controller 154 may control the eyepiece adjusting device 151 and/or the objective adjusting device 152 to stop the adjustment operation and control the optotype display screen 140 to display the color vision checking mark for color vision checking.
In some embodiments, diopter check device 100 may also be used to check the user's astigmatism. Specifically, the controller 154 (or the diopter determination module 630) may control the diopter adjustment means 150 to stop the adjustment operation according to the first feedback information of the user. On this basis, the controller 154 can control the astigmatism adjusting means 180 to adjust the astigmatism of the examination apparatus 100; and determining the astigmatism information of the user according to the fourth feedback information of the user. The fourth feedback information may be feedback information of the user on the optotype or the astigmatism map or the like in the process of adjusting the astigmatic lens. For example, the controller 154 may control the astigmatism adjustment device 180 to switch the astigmatic lens to adjust the astigmatism of the diopter check apparatus 100; the user can give feedback on the situation where he sees the most clearly, in which case the degree of astigmatism of the examination device 100 is the degree of astigmatism of the user. For another example, the controller 154 may control the astigmatism adjustment device 180 to rotate the astigmatic lens to adjust the astigmatism axis of the diopter inspection apparatus, and the user may give feedback on the clearest view of the user, in which case the astigmatism axis of the inspection apparatus 100 is the user's astigmatism axis. If the information fed back by the user is that the visual target or the astigmatism graph seen in the process of the rotation of the astigmatic lens is rather blurred, and the situation that the conversion of different axis positions is not improved, the user can be determined to have no astigmatism.
In some embodiments, the diopter check device 100 may also perform a user's eye disease check. For example, when the first feedback information of the user is feedback of the user on being able to see the clear optotype, the controller 154 may control the eyepiece adjusting device 151 and/or the objective lens adjusting device 152 to stop the adjustment operation, and control the optotype display screen 140 to display the amsler grid table, if the grid seen by the user is shaded by a black shadow, the grid size of the unit is different, or the lines are deformed, it indicates that the eye examined by the user may have maculopathy.
It should be noted that the above description related to the flow 500 is only for illustration and explanation, and does not limit the applicable scope of the present application. Various modifications and changes to flow 500 may occur to those skilled in the art upon review of the present application. However, such modifications and variations are intended to be within the scope of the present application. For example, in performing a diopter check, controller 154 may control inspection apparatus 100 to perform a wide range of one-way diopter adjustments (e.g., from 0D to-10D) to allow the visual target seen by a user with myopia (e.g., -5D myopia) to be both clear and blurred from blur; on this basis, the examination apparatus 100 again adjusts the diopter reversely so that the optotype viewed by the user gradually changes from blurred to clear. Since the user already knows the process of the whole sighting target change, the user can more easily feed back the relatively clearest position seen by the user. For another example, when determining the astigmatism information of the user, the controller 154 may first make the chart displayed on the sighting target display 140, and then obtain the feedback corresponding to the user (e.g., which direction line is clearer) from the control device 153 to make a pre-determination on the astigmatism information of the user.
Figure 6 is a block diagram of a diopter check system 600 according to some embodiments of the present application. As shown in fig. 6, the diopter check system 600 may include a diopter adjustment module 610, an information acquisition module 620, and a diopter determination module 630. In some embodiments, the diopter check system 600 may also be executed by the controller 154, and the diopter adjustment module 610, the information acquisition module 620, and the diopter determination module 630 may be respective modules in the controller 154.
The diopter adjustment module 610 may be used to adjust the diopter of the diopter check device 100. In some embodiments, the diopter adjustment module 610 may adjust the eyepiece 110 and/or the objective lens 130 using the diopter adjustment device 150 to change the diopter of the inspection apparatus 100. For example, the diopter adjustment module 610 may send adjustment instructions and/or data to the eyepiece adjustment device 151 and/or the objective lens adjustment device 152, respectively, such that the objective lens adjustment device 152 adjusts the objective lens 130 and the eyepiece adjustment device 151 adjusts the eyepiece 110.
The information acquisition module 620 may be used to acquire various information/data during the diopter check. In some embodiments, the information acquisition module 620 may acquire feedback information of the user. For example, the information acquiring module 620 may receive feedback information of the user acquired by the manipulating device 153. In some embodiments, the information obtaining module 620 may also obtain information input by the user (e.g., user information input by the information input device 170, eye examination information, etc.) or obtain information (e.g., user information, etc.) from a server, database, memory, etc.
