Embodiments of the present application are described in detail below.
The application provides a refraction detection method, as shown in fig. 5, which is a flowchart of the refraction detection method provided by the embodiment of the application, comprising S101-S104.
S101, obtaining objective refraction degree of eyes of a user.
In the embodiment of the application, the imaging position of the fundus or cornea reflected light of the user can be measured through a computer optometry instrument or a vision screening instrument based on the photographic optometry principle, so that the refraction state can be determined.
Specifically, during detection, the user may look at the target in the machine according to the system prompt, so that the instrument detects the objective refraction degree of the eyes of the user. The application can embody the optometry principle through an optical system in the instrument, and then obtains the degree required by correcting vision after being processed by an electronic computer. The method for obtaining the objective optometry degree of the user by the vision screening instrument based on the computer optometry instrument or the photographic optometry principle has the advantages of high speed, no pain, easy acceptance of the user, easy mastering and the like. And obtaining the objective refraction degree so as to further perform subjective refraction test on the user based on the objective refraction degree, so as to more accurately determine the refraction state of the eyes of the user.
In one possible implementation, to ensure that the user can perform refractive testing, it is necessary to determine that the eye condition of the user is normal before obtaining the objective refractive power of the user's eye, so as to ensure the accuracy of the refractive testing result.
Specifically, before objective refraction degrees of eyes of a user are obtained, an eyeball movement test instruction and a pupil size test instruction are sent to the user; determining the eye state of the user according to the eye movement test result and the pupil size test result of the user, wherein the eye movement test result is obtained by the user according to the eye movement test instruction, and the pupil size test result is obtained by the user according to the pupil size test instruction; and when the eye state of the user is normal, sending an objective Qu Guangce test indication to the user.
Whether the eye state of the user is normal or not can be judged through the eye movement test and the pupil size test, and an eye movement test instruction can be issued to the user by displaying a moving target on a screen to prompt the user to move with the moving target, so that an eye movement test result of the user is obtained. Pupil size testing results may be obtained by measuring the diameter of the pupil.
In one possible implementation, the original eye information of the user may be obtained before the objective prescription of the user's eye is obtained. Based on the original eye information of the user, the original eye condition of the user, such as whether the eye state of the user is normal, the original refraction degree, astigmatism degree and the like, can be obtained. Based on the original eye information of the user, a certain reference can be provided for the subsequent refraction detection of the user, and the accuracy of the refraction detection result is improved.
S102, responding to a first observation result of a user on the character visual chart, adjusting the degree of an initial lens to be the initial refraction degree, and obtaining an adjusted lens, wherein the first observation result is obtained by the user observing the character visual chart through the initial lens, and the degree of the initial lens corresponds to the objective refraction degree.
Specifically, after obtaining the objective prescription, a lens adjustment command may be sent to the phoropter lens control group, which provides the user with an initial lens having a prescription corresponding to the objective prescription. While the corresponding character's visual chart is displayed on the screen, whereby the user can observe the character's visual chart through the initial lens. According to a first observation result fed back by a user, the initial diopter number can be obtained according to logic, and the comprehensive optometry lens control group can adjust the power of the initial lens to the initial diopter power, so that the adjusted lens is obtained.
Illustratively, taking an "E" character visual chart as an example, after obtaining the objective refraction degree of the eyes of the user, the "E" character with a corresponding size can be displayed on the screen according to the objective refraction degree of the eyes of the user. The user can feed back the first observation result through voice, gestures or handle remote control and the like. Wherein the first observation may include the opening direction or sharpness of the "E" letter, etc.
It should be noted that, in the present application, the number of "E" marks displayed in each screen is not specifically limited, and, for example, a row of "E" marks may be displayed on the screen each time, or a single "E" mark may be displayed on the screen, where the opening direction of the "E" marks is a random direction.
In one possible implementation manner, when the feedback of the user on the opening direction of the first character in the character visual chart is an error result, the first character is switched to the second character; and when the feedback of the user to the opening direction of the second character in the character vision chart is a correct result, adjusting the degree of the initial lens to be the initial refraction degree according to the size of the second character, and obtaining the adjusted lens.
Wherein the size of the second word mark is larger than the size of the first word mark. That is, when the feedback of the user to the opening direction of the first word mark in the word mark visual acuity chart is an error result, the size of the first word mark is indicated to be smaller for the user, the user cannot see the first word mark, and the size of the word mark needs to be increased to find the word mark which the user can just see, so as to obtain the initial refraction degree. And switching the first word mark into a second word mark, when the feedback of the user on the opening direction of the second word mark in the word mark visual acuity chart is a correct result, indicating that the user can see the second word mark clearly, and adjusting the degree of the initial lens to the initial refraction degree according to the size of the second word mark at the moment to obtain the adjusted lens.
Specifically, as shown in fig. 6, the figure is a flowchart for obtaining an initial refractive power based on a word mark visual acuity chart according to an embodiment of the present application.
Based on the objective refraction degree, after the character vision chart is displayed on the screen, a query is sent to the user, such as displaying in the screen, or a voice is output to ask whether the E' character direction is clear. If the user feedback is unclear or the opening direction of the wrong E word mark is fed back, reducing the positive lens power (+ 0.25D); if the user feedback is clear and the correct opening direction of the E word mark is fed back, judging whether the E word mark reaches 5.0. If the E word mark reaches 5.0, the detection is finished, and the current sphere power is the initial refraction power; if the E character does not reach 5.0, the character is added, namely the next row of the E character visual chart is jumped, and the inquiry is continued until the user feeds back the correct opening direction of the E character when the E character reaches 5.0.
S103, displaying an optometry table based on the initial refraction degree and the astigmatism degree of the user, wherein the optometry table comprises at least one of a red-green test table and an astigmatism test table.
S104, responding to a second observation result of the user on the optometry table, and obtaining the diopter number of the user, wherein the second observation result is obtained by the user through observation of the optometry table through the adjusted lens.
In one possible implementation manner, based on the acquired original eye information of the user, the astigmatic condition of the user can be obtained, and if the astigmatism exists in the user, the astigmatic degree of the user is detected; if the user has no astigmatism, the diopter of the user is detected based on a red-green test table.
In one possible implementation, the degree of astigmatism of the user needs to be detected when it is not determined whether or not astigmatism exists in the eyes of the user, i.e. the original eye information of the user is not acquired, or the astigmatism is not included in the original eye information of the user.
Specifically, if the objective refraction degree of the user is smaller than the preset objective refraction degree threshold, the refraction table is a red-green test table, the second observation result is red and clear, and the responding to the second observation result of the user on the refraction table, the obtaining the refraction degree of the user includes: reducing the initial diopter number of the adjusted lens by a preset degree in response to a second observation result of the user on the optometry table, and obtaining a reduced lens; and responding to a clear consistency result obtained by the observation of the optometry table through the reduced lens by the user, and taking the degree of the reduced lens as the refraction degree of the user.
And if the objective refraction degree of the user is smaller than the preset objective refraction degree threshold value, the user is considered to have no astigmatism. Illustratively, a user is considered to be free of astigmatism when the objective prescription is less than 1.0 DC. In this case, as shown in fig. 7, the flow chart of the refraction detection based on the red-green test table according to the embodiment of the application is shown.
The electronic device displays a red-green test chart on the screen, sends a query to the user, such as in the screen, or outputs the voice "whether the visual target definitions of the green background and the red background coincide. If the user feedback is inconsistent and the feedback is clear, i.e., the second observation is clear, the electronic device reduces the red background (+0.25d) and again queries. If the electronic equipment obtains a definition consistent result fed back by a user, reducing the initial diopter by a preset degree to obtain a reduced lens, and taking the degree of the reduced lens as the refraction degree of the user; if the electronic equipment obtains that the definition result of the user feedback is still red and clear, the red background is continuously reduced (+0.25D) until the definition of the user feedback is consistent. If the degree deviation exceeds the preset value, reporting errors, namely exiting, and prompting the user to consult the manual service.
In response to a second observation result of the user on the optometry table, increasing the initial diopter number of the adjusted lens by a preset degree to obtain an increased lens; and responding to a clear consistency result obtained by the observation of the optometry table through the added lens by the user, and taking the degree of the added lens as the refraction degree of the user.
If the user feedback is inconsistent and the feedback is clear, i.e., the second observation is clear, the electronic device will increase the green background (+0.25d) and query again. If the electronic equipment obtains a definition consistent result fed back by a user, increasing the initial diopter by a preset degree to obtain an increased lens, and taking the degree of the increased lens as the refraction degree of the user; if the electronic equipment obtains that the definition result of the user feedback is still green and clear, the green background is continuously increased (+0.25D) until the definition of the user feedback is consistent. If the degree deviation exceeds the preset value, reporting errors or prompting the user to consult with the manual service.
And if the objective refraction degree of the user is greater than or equal to the preset objective refraction degree threshold value, the user is considered to have astigmatism. Illustratively, a user is considered astigmatic when the objective refraction number is greater than or equal to 1.0 DC. The prescription is an astigmatism chart comprising an astigmatism disc and a cellular optotype, the obtaining the diopter number of the user in response to the second observation of the prescription by the user comprises: responding to a sub-first observation result obtained by the user through the adjusted lens and observing the astigmatism disc, and obtaining the corresponding power of the astigmatism disc; and responding to a sub-second observation result obtained by the user through the astigmatic lens and observing the honeycomb optotype, and obtaining the refraction degree of the user.
Specifically, in response to a sub-first observation result obtained by the user observing the astigmatism disc through the adjusted lens, adjusting the degree of the adjusted lens according to the label corresponding to the clear line fed back by the user to obtain an adjusted astigmatism lens; and responding to a line definition consistency result obtained by the observation of the user through the adjusted astigmatic lens, and taking the power of the adjusted astigmatic lens as the refraction power of the user.
Exemplary, as shown in fig. 8, the figure is a flowchart of a refractive detection based on a scattered optical disc according to an embodiment of the present application.
The electronic device displays the hash disk on the screen, sends a query to the user, such as in the screen, or outputs a voice "whether all lines are clearly consistent". If the feedback definition is consistent when the user inquires for the first time, the verification is finished, and the user has no astigmatism; if the user feedback is inconsistent, the user feedback is responded, the user feedback is displayed in a screen, or the voice 'line is the clearest' is output, and the degree of the adjusted lens is adjusted according to the label corresponding to the clear line fed back by the user, so that the adjusted astigmatic lens is obtained.
Specifically, after the label corresponding to the clear line fed back by the user, multiplying 30 by the sharpest smaller label fed back by the user to obtain a calculation result, taking the calculation result as the axial direction, and gradually increasing the lens power with 0.25DC as the gradient until the definition of the line fed back by the user is consistent. By way of example, the user feedback is most clear for lines numbered 2 and 8, and 60 is obtained based on 2×30, with 60 ° as the axial direction, i.e. the cylindrical astigmatism direction of the eye is 60 °. If the power of +0.25DS is adjusted 4 times, each time, 4 times is 100 degrees, the user can be determined to have astigmatism.
After the clarity of the feedback lines of the user is consistent, the electronic device judges whether the astigmatism degree and the objective refraction degree differ by less than or equal to 30 degrees. If the angle is larger than 30 degrees, reporting errors so that the user can consult the manual service; if less than or equal to 30 °, the user may be further subjected to refractive detection based on the cellular optotype.
Fig. 9 is a flowchart for determining the axial position of a cylindrical lens based on a cellular vision standard according to an embodiment of the present application.
Specifically, in determining the axial position of the cylinder, the electronic device displays a cellular optotype on the screen, and issues a query to the user, such as in the screen, or whether the output voice "A, B face is as clear. If the user feedback is not clear, judging whether the absolute value of the cylindrical lens is smaller than 1.0D. If the absolute value of the cylindrical lens is smaller than 1.0D, the electronic equipment performs fine adjustment on the basis of the clear surface, and when the feedback A surface of the user is clear, the axial position of the cylindrical lens is reversed by 10 degrees; the B-plane is clear in response to user feedback and the cylinder axis is rotated 5 ° clockwise. If the absolute value of the cylindrical lens is larger than or equal to 1.0D, the electronic equipment performs fine adjustment on the basis of the clear surface, and when the feedback A surface of the user is clear, the axial position of the cylindrical lens is reversed by 5 degrees; the B-plane is clear in response to user feedback and the cylinder axis is rotated clockwise by 2.5 °.
After the axial position of the cylindrical lens is adjusted, judging whether the phase difference between the axial position of the adjusted cylindrical lens and the initial axial position is larger than 30 degrees. If the angle is larger than 30 degrees, the astigmatism change of eyes of the user is larger, and error reporting can be carried out, so that the user can consult with manual service. If the axial position is smaller than or equal to 30 degrees, the axial position of the cylindrical lens of the user is determined by the adjusted axial position. On this basis, the refractive power of the user may be further determined based on the cellular optotype.
Fig. 10 is a flowchart of refractive detection based on a cellular optotype according to an embodiment of the present application.
The electronic device displays a cellular optotype on the screen and sends a query to the user, such as in the screen, or outputs the voice "A, B as clear as possible. And if the feedback definition of the users is consistent, determining the axial position of the cylindrical lens. On this basis, the cell optotype is still on the screen, and a query is sent to the user, as displayed in the screen, or whether the output voice "A, B face is as clear. If the feedback A surface of the user is clear, adding-0.25 DC to the cylindrical lens, judging whether the absolute value of the added degree is greater than or equal to 1.0DC, if so, reporting errors so that the user can consult manual service; if not, continuing to inquire whether the A, B surface is as clear or not until the feedback definition of the user is consistent. If the feedback B surface of the user is clear, the cylindrical lens is reduced by-0.25 DC, whether the absolute value of fewer degrees is larger than or equal to 1.0DC is judged, if yes, error reporting is carried out, and therefore the user can conveniently consult manual service; if not, continuing to inquire whether the A, B surface is as clear or not until the feedback definition of the user is consistent.
In one possible implementation manner, in order to further improve accuracy of the refraction detection result, the binocular vision balance test can be performed on the user after determining the axial position and the power of the cylindrical lens.

If the right eye is clear, judging whether the walking eye is a dominant eye, if the right eye is the dominant eye, the degree of the right eye is unchanged, the degree of the left eye is increased by 0.25DC, and if the left eye is the dominant eye, the degree of the right eye is unchanged, and the degree of the left eye is also unchanged; if the left eye is clear, the degree of the left eye is increased by 0.25DC, and then information prompt is output again, if the right eye is clear, the degree of the left eye is increased by 0.5DC under the condition that the right eye is a dominant eye, the degree of the right eye is unchanged, and under the condition that the right eye is not the dominant eye, the degree of the left eye is increased by 0.25DC, and the degree of the right eye is unchanged.
