Description

200304606 Description of the invention (Invention description should be made clear ... The technical field to which the invention belongs, prior technology, content, embodiments, and drawings are briefly explained. [Technical field to which the invention belongs] Field of the invention The invention relates to glasses and contact lenses The degree determination system is 5 and this method, especially regarding the use of a distance conscious vision measurement system (how many people can measure conscious vision at the same time on the Internet or determine the power of glasses and contact lenses) The power of the lens determines the system and method. C Previous j 10 Background of the Invention To date, eyeglass models have been used to select spectacle lenses. Gullstrand's model eyes and Le-Grand's model eyes are very well known. This model eye is specifically used for the design and evaluation of spectacle lenses. When designing spectacle lenses, if you prepare a standard 15 model as the optical model of the eye, you can design lenses of various degrees for the standard eye situation. The reason for this is that, regardless of the human eye's How the structure is, the power of the spectacle lens that can be selected is 0.25D. If you actually try on the glasses, you will be able to find a spectacle lens that is suitable for correcting vision. In other words, ‘because there is a degree of freedom of choice. 20-In terms of naked eyesight or corrected vision at an ophthalmologist or optician. In recent years, for example, although an imaginary shop title has been formed on a network such as the Internet, there is no system that can measure naked eyesight and bridge vision in an eyeglass shop installed in this imaginary shopping street. . 200304606 发明 、 Explanation of the invention But when 疋 ’wants to determine the power of the human eye, if the optical model of the eye like the eyeball model is considered to be the same, the optical error will be large, and the power cannot be determined. This can only be achieved by constructing optical models of individual eyes one by one. 5 Using the conventional model eyes directly has the following problems. • The conventional model eyes are based on the measured values of Europeans and Americans. For other species, for example, if you want to build a model that is close to the measured value of the Japanese living eye, the conventional model eye cannot be used. For example, the curvature radius of the cornea is smaller than that of the Europeans and Americans. 10 'creates a model based on the average of the measured values. According to the literature, the anterior chamber depth changes with age. The shape of mild myopia, the axial length, and myopia are related. Obviously, it is necessary to build an optical model of the eyeball corresponding to each person's age and myopia. • Contrary to the unequal distribution of the refractive index of the crystalline lens, the average refractive index is used. The structure of the crystal is simply divided into two structures, which is too simplistic, which leads to a large error in the ray tracing result. On the other hand, when it is difficult to go to an ophthalmology or optician shop due to time and distance, it is expected that a system capable of measuring distance vision through the Internet will appear. ’'

In particular, the glasses or contact lenses worn today are not as clear as before. In order to determine whether it is necessary to change the glasses or hide the I glasses, 'If you can measure naked eyesight or corrected vision after a long distance, Would be extremely convenient.

In this embodiment, based on the contents of the above-mentioned document data, the following parameters are introduced for the lenses of each layer of the crystalline lens constructed by the eyeball optical model determination means. In the following, the parameters introduced for the 10 optical elements of the crystalline lens corresponding to the optical model of the eyeball will be described. The aspheric surface of the lens of each layer of the crystalline lens constructed by the optical model construction method of the sphere lens is determined as shown in the following formula [Formula 1] CY2 l + A / l- (K + l) C2Yr + A4Y + Α6γ6 + Α8Υ8 +. ··· 15 In formula 1, R is the reference spherical radius, CS 1 / R, κ is the eccentricity 52 200304606 发明, the description of the invention is based on 1 aspheric coefficient A 1 一 # μ AA / 4 A6 'As ..... The shape of the lens can be fully expressed, and the average value is 0. Each lens simulating a crystalline lens is composed of ten different materials in different parts. As shown in Fig. 36, the refractive index is expressed by (refractive index with a distance r in the direction orthogonal to the center of the lens and the optical axis of the optical axis) as shown below. [Formula 2] nr ~ Πγ0 ~ Δn (r) b However, in formula 2, nr0 is the refractive index of the lens center, and palpitation is the amount of refractive index corresponding to the decrease in distance from the center of the lens ⑴ 10 as the following formula As shown. [Formula 3] Δπ (γ)-r2 / Ks Ren, in Formula 3, Ks is a refractive index distribution coefficient, and this value indicates the degree of unevenness of the refractive index distribution of the lens. The value of this coefficient varies from lens to lens based on the data in the above C literature. Focusing on the ten heart 4 of the crystalline lens, the higher the refractive index, as shown in Table 3, the closer to the center of the optical axis direction of the complex lens, the higher the numerical value.

In this embodiment, the power distribution coefficient α is used to change the optical elements of each lens as the refractive index distribution coefficient Ks, the aspherical surface coefficient K, and the radius of curvature R. An example will be described below. When the optical elements of the eyeball optical model located at the adjustment midpoint are determined, it is assumed that adjustment is made only from the adjustment midpoint to the -aE) side (near point distance) or + aD (far point distance) side. Here D refers to the adjustment force, and the value is expressed by the reciprocal of the distance (in meters) from 15 to the focal point of the lens. On this day, for the bD adjustment only on the relaxation side, the elements of the crystalline lens of the eyeball optical model use the force distribution coefficient α, by making the refractive index distribution coefficient ks aspheric coefficient κ and the radius of curvature R of the adjustment midpoint. The value (1 + α xb / a) is doubled, and an eyeball optical model that simulates a relaxation state is determined. On the contrary, when the bD adjustment is performed only on the tension side, by doubling the value of the optical elements (l-α xb / a) at the midpoint of the adjustment, an eyeball optical model that simulates tension is determined. In this way, the initial eyeball optical model changes the above-mentioned optical elements of the crystalline lens according to the adjustment force, and an eyeball optical model indicating an arbitrary degree of relaxation or tension is constructed. 54 200304606 发明, description of the invention In an example, the lens power of the near-point distance of the optometrist is -10.2D, and the distance of the far-point distance is -02D, the lens power of the mid-point adjustment becomes -5.02 D. When the refractive index distribution coefficient Ks of each lens located at the adjustment midpoint is the value shown in the second column from the left side of Table 4, the value of α and the adjustment amount of each lens, the relaxation side and the tension The refractive index distribution coefficient Ks on the side is a value shown in Table 4.

The model's suitability verification means 4206 'adjusts the adjustment limits at the midpoint, near point, and far point 5 to verify the validity of the eyeball optical model. The eyeball optical element adjustment range determination means 4208 can determine the adjustment range of the eyeball located at the midpoint of the adjustment, and can represent an image of the eyeball optical model that determines the adjustment range of the eyeball located at the midpoint of the adjustment. The method for verifying the focusing performance of eyeball optical model 4212 corresponds to the use purpose. The focusing state of eyeball optical model at three distances determined by 1 should be tested I ·. The three distances are 0.3 meters (close distance) for reading and desktop work, 0.5 ~ 0.6m (medium distance) for computer work, and 5 meters (long distance) when driving. The eyeball optical model condensing performance verification means 4212 also has a function of comparing and verifying the condensing state of the eyeball optical model of the naked eye state. 15 The visual image forming means 4214 forms a visual image of the examinee before or after vision correction. The sharpness score forming means 4216 derives the visual sharpness score of the examinee before and after correcting vision. 56 200304606 发明 、 Explanation of the invention The user customer 4001 is a terminal device proposed by the user for vision measurement, and is implemented by a personal computer, for example. The user customer 4001 is a wheel-out device that becomes a circuit between the user and the user. Specifically, it is realized by an input device such as a keyboard and a mouse, and an output device such as a display screen. The user customer 4001 has access means such as the global information network server 30 of the eyewear sales service Lingxin 002 and the global information network browser as a circuit for data exchange. If the customer side of the user is a personal computer, the global information network browser is implemented by a program stored in the memory 10. The following describes how the system is implemented using a homepage or the like on the Internet. / For the first time, the glasses order lock service Lingxin 4002 launched the homepage on the Internet through the global information network server 30. 15 The user accesses the user information with the homepage of the glasses ordering sales service spear gunnery ~ 4002 through the access means such as the user's global information network of 4001, which is a user customer connected to the Internet. Management measures 42, require vision measurement. 20 The glasses order lock sales service center 4002, through the user authentication means owned by the Global Information Network Feeder 30, the user's pass code or the user's authentication information, after verifying that the user is a officially registered member, User information management method 42 of the glasses ordering sales service center 002. The user requests registration and sending information through the Internet to enter the user information database for management. 57 200304606 发明 、 Explanation of the invention At this time, when judging that the user is using the vision measurement system for the first time, enter the basic information such as the address name, date of birth, phone number, etc., the condition of the glasses (I can't see clearly near them). The data such as the request is sent to the user's customer's face through the input screen such as the basic situation, and the user inputs the necessary items through the user: 5 The customer's face is sent to the glasses custom lock service center 4002. The user registers the pass code and ID, and the user information management means 4230 inputs user information into the user information database and manages it through the Internet. '10 The structure of each database managed by the database management means 4232 in the glasses order sales service center 4002 is as follows. In the user information database, as the specific user information, it contains the basic information such as user number, ID, user pass code, address, name, date of birth, phone number, etc., and stores user information. 15 Some user information is data (input from the user information registration day and day sent from the user information management device 4230 to the user customer 4001). The user number is registered and registered. For the Wang # project, the data does not have to be fully registered. The ID and pass code are based on the user information obtained through the out-of-line method, and can be determined by the service center or automatically assigned when the user first visits. User's purpose of use, near-point distance, far-point distance, age, monthly degree of both eyes, left-right balance of front degree, years of use of front glasses, type of contact lens, vision correction, presence or absence of vision-related diseases Etc. 58 200304606 发明, description of the invention. First, the measurement of naked eye vision will be described. User customer 4001-Connected to the glasses ordering sales service center 4002 and sent the ID number input screen from the user 5 screen. The user recognizes the 5 ° standing face, which prompts the user to enter user authentication information. The user customer 4001 receives and displays the user authentication screen, enters the user authentication information, and sends it to the glasses order sales service center 4002. User authentication information includes information such as pass codes and users 1] 〇. The glasses order sales service center 4002 receives the user authentication information, and based on this, it uses the database management means 4232 and the user information management means 4 230 to retrieve and authenticate the user information database. The glasses order sales service center 4002 sends the service type screen as the user member homepage to the user customer 4001 through the database management means "M 15" The user customer 40001 receives the service type day and day and displays it.- If you want to measure naked-eye vision in the daytime service category, you only need to click "Bare-eye vision measurement". In this case, the wearing condition input screen will be sent by the glasses ordering and selling service center 4002 to the customer's customer via Global Capital Cotai. As the wearing conditions, there are the purpose of wearing glasses and contact lenses (for example, when looking at the near, distant, driving, etc., when do you want to wear, etc.) and the visual environment (normally how much distance to see in what range) There are a lot of things, do you have a lot of computer work at work, etc.? Hun sales service center 4002 please send user information through the global information network server n round in 61 200304606 发明, invention description user information input screen prompts users to enter users Personal information (user number, 1D, pass code, address, name, date of birth, etc.), purpose of use, far point distance, far point distance, age, anterior degrees, binocular vision at anterior degrees, anterior degrees The left and right balance at the time, the number of years of use of the front glasses, the type of contact lenses (when used with glasses), the hope of correcting vision, the presence or absence of eye-related diseases, etc. Next, the glasses order sales service center 4002 Send the naked eye vision measurement daytime surface to the user customer 001 through the global information network server. First, the astigmatism index shown in Fig. 38 will be displayed. Check the vision while changing the distance within the range 10. The user covers his hand with one eye and looks at the measurement screen with the other eye. On the naked eye vision measurement screen, an image or visual target for measuring one eye is displayed. Next, The user fixes the head and neck in a fixed distance from the 15-day vision measurement with naked eyes. For example, hold the fat part with the palm of your hand and place your elbow on the table. Then, measure the near point distance. The eye can see the picture clearly The shortest distance between the eye, the moon, and the screen at the time of the image above is the near point distance. Then, the far point distance is measured. The eye can see clearly the picture on the screen. The distance is the far point distance. Measure the distance between the screen and the eye horizontally with a ruler and enter it. Next, how to determine the power of the glasses and contact lenses will be explained based on the flowchart shown in Figure 39. First, as the information about the state of the eye of the examinee, the near-point distance to be measured is entered on the input hand 62 200304606 发明, invention description 又 4 2 02 through a global information web browser. Far point distance, wearing conditions, and age input.… Age is related to the adjustment power of glasses, especially the elasticity of the lens. The adjustment power decreases with age (see Figure 37). The reason is that the crystal 5 The body's 5 early strength decreases with age, and the change in zigzag force becomes difficult due to the change in distance. Although the tuning force decreases with age, it can be estimated that the same age People have roughly the same adjustment power. Second, based on age, near-point distance, and far-point distance, you can determine the approximate lens power of glasses and contact lenses. Then you can calculate the adjustment midpoint position based on the approximate lens power. For example , The distance between the far point is i meters, and the distance between the near points is cm. The lens power required for correction at the far point is _100, and the lens power required for correction at the near point is portable. The estimated lens power of 15 is (-1-4) /2=-2.5D. The distance of k% is 40 cm. This 40 cm distance is the midpoint of the adjustment. Next, the eyeball optical model determination means 4204 determines the initial eyeball optical model based on age and likelihood. ί〇 The initial eyeball optical model is an eyeball optical model created in advance with age as the vertical axis and estimated lens power as the horizontal axis, with intermediate values in each axis. If the vertical axis is divided into M equal parts and the horizontal axis is divided into N equal parts, there are M × N initial eyeball optical models. That is to say, with age as the vertical axis (for example, 5 years old up to 20 years old, 63 200304606), the description of the invention 'fuzzy portrait, the degree of blurring is N (minimum 3), repeated considerations, can be processed by the number of times Adjustment. Regarding the processed image ', determine the degree of blurring through spatial frequency analysis, and calculate the score of the sharpness of 5 degrees by calculating the score of the sharpness (A) above. Prepare a few with sharpness. The image corresponding to the score. At the same time, calculate the score value corresponding to the image that has been subjected to a specific smoothing process for the prepared image. For example, if the score value is calculated by calculating the score of the sharpness in the preface (A) 1 〇, according to the score value, or call up the corresponding portrait, or take care of processing, so that the resulting image and sharpness score are consistent and expressed. Further, according to visual image generation means 4214, the lenses are exchanged, and the prompt is at 3 distances. The day image of the viewing method makes it possible to compare. That is, changing the power of the lens and performing optical simulation when wearing glasses and contact lenses. 15 In order to change the optical elements in the adjustment range of the eyeball, resulting in the best condensing performance, calculate the sharpness score at this time. In addition, according to the specific power of the specific lens power of the lens power selection means 4218 If the degree score has been calculated, the data can be used directly. 20 As mentioned above, the glasses ordering and sales service center 4002 uses the global information network of the 4220 output means to generate the sharpness of the face image of the viewing method. The score is sent to the customer who is the user 400j. The subjective vision measurement result prepared separately is sent to the user's customer through the screen of the subjective vision measurement result and displayed. The subjective vision measurement 72 200304606 The results include the following: msT (remote power), Read (remote power), SPH (represents aspheric power), CYL (represents astigmatism), AXIS (represents axis), PD (represents between eyes) Distance). 5 In addition, distance power and near power, both of which indicate the right eye and the left eye. The current computer optometry is best for distance vision After the lens is selected, after the optometry, the lens is actually worn, and the selected lens power is adjusted with reference to the wearing situation. According to the invention, the objective is to calculate the sharpness through the viewing method of the complex distance H when wearing a lens. Score, so referring to the initial input of the wearing conditions, the balance of the viewing methods at three distances can suggest the best degree of wearing comfort. In other words, the current situation is a self-conscious inspection to confirm the actual "wear condition". Although it is necessary, it can be omitted here. Choose the most suitable for online shopping. 15 In addition, in the implementation form, an eyeball optical model of the adjustment center of the examinee was constructed. Not limited to this, an eyeball optical model of an arbitrary point between the near-point distance and the m-point distance of the examinee may be constructed. In this case, according to the adjustment position of the eyeball optical model, by assigning the “weekly” force on the tension side or the slow side, the moon dagger can build an eyeball optical model on the near side & far distance side of the adjustment 20 limit. In the above implementation state, as the initial value of the automatic design process for the purpose of constructing the examinee's unique eyeball optical model, the age is divided into M's and the approximate lens is divided into N's based on the core. The initial eyeball optical model is not limited to this, but the eyeball optical model that is most suitable for the data input by the examiner 73 200304606 发明 and the inventor may be used as the initial value of the optical automatic leafing process. The estimated lens power corresponding to the sum of ^ input by the examinee is based on the difference from the central value of the difference! The eyeball optical model corresponding to the state of the examinee's eyeball is used as the initial value. , Using the initial eyeball optical model constructed in advance from the central value, compared with automatic error correction Difference correcting.

One step further. In this embodiment, the value of W using fuzzy judgment can be determined from the decomposition of the omentum. Although the number of sharp and sharp knives obtained from the U value at this time is calculated, alas, it is not limited to this and can be used. Calculate the number of sharpness in other methods. For example, if the spatial frequency of the incident light is changed and the TF value is 70%, find the value of the spatial frequency at this time. At this time, the spatial frequency of the incident light is changed within a certain range within a certain period of time, the lowest spatial frequency is 0, and the highest spatial frequency is 100. 〇 developed to 100 sharpness.

In addition, in the implementation state, the inspected person is allowed to view the visual image generated by the visual image generating hand 216 and 216 as it is, but it is not limited to this. After correcting the degree of blurring of the image, it can also be viewed by The inspector prompts the image. This is because when a person sees an object / landscape and similar objects / landscapes 20, even if it is a blurred image, the person's memory of the object / landscape that has been seen only once supplements the image information and feels visual recognition. Image tends to look very clearly. Therefore, specifically, for a large number of examinees, the difference between the image generated by the visual image generation means 216 and the blur degree actually felt when the examinee visually recognized it was verified. Created based on the verification results 74 10 200304606 玖, description of the invention The four directions are known because even in the four directions, it is possible to select the glasses and judge the ancient dagger to be practical enough. Because it is the examinee's own detail, it is necessary to make the determination as easy and error-free as possible. ‘People ’s relatives, regarding the selected orientation selected by the subject, the visual acuity of the chosen orientation is shown in Table ⑽), and the visual inspection limit / presence of visual inspection-existing threshold data obtained is obtained). The paste is an example of a far-sighted vision measurement screen, and Fig. 49 is an example of a far-sighted vision measurement screen. As shown in the figure, the visual acuity measurement table is a linear shading portrait composed of 3 black lines and 2 self-lines with a fixed line width. Corresponding to visual acuity, the line width is changed from the [] stage to the 20 stage. ). In response to this, the three smallest symbols that the examinee ^ month b saw were prompted. In this way, because the selection looks like three symbols, like a visual chart circle ring, it is easy for the examinee to judge the single gap. In addition, the distance between the subject and the arm of the computer screen is used to measure the far-sighted vision. ^ Is because the length of the arm is roughly proportional to the height. Based on the height data input in advance, the subject and the vision can be measured. The distance between the tables. In this way, because the subject does not need to measure the distance from the computer screen, and it is not necessary to adjust the size of the daytime display, the measurement can be easily performed. Similarly, in order to measure the visual acuity of the far point with respect to the selected orientation selected by the subject and the orthogonal 20 orientation, a visual acuity measurement table (S22) showing the selected orientation and orthogonal orientation is acquired, and the visual recognition limit selected by the subject is obtained and saved. In the second visual limit data (S24). Next 'is to measure the near point distance of the azimuth selected by the subject, indicating the near point distance measurement table for selecting the orientation (S26), and the near point input by the subject

77 200304606 玖 、 Explanation of invention The distance is stored in the near-point distance data (S28). Fig. 50 is an example of a daylight surface at the near-point distance measurement, and Fig. 5 is an example of a near-point distance measurement screen. As shown in the figure, the near-point distance measurement table is composed of three black lines set in a green background.
