Description

1223764 发明 Description of the invention (the description of the invention should state: the prior art, the content, the embodiment, and the drawings are briefly explained in the technical field to which the invention belongs) The power determination system is based on 5 and this method, especially regarding the use of a distance conscious vision measurement system (how many people on the Internet can measure conscious vision at the same time or determine the power of glasses and contact lenses). Intact glasses and contact lenses The power of the lens determines the system and method. [Previously 3 10 Background of the Invention To date, eyeglass models have been used to select spectacle lenses. GuUstrand's model eyes and Le-Grand's model eyes are very well known. Irregular eyes are used exclusively for the design and evaluation of spectacle lenses. When designing an ophthalmic lens, if a standard 15 model is prepared as an optical model of the eye, it is possible to design lenses of various degrees in the case of the standard eye. The reason for this is that, regardless of the structure of the human eye, the degree of spectacle lenses that can be selected is in units of 25D. The actual try-on of spectacles must not be enough to find suitable spectacle lenses for correcting vision. In other words, ‘because there is a degree of freedom of choice. 20 — In terms of naked eye vision or corrected vision, it is now measured at an ophthalmology or optician. In recent years, for example, although an imaginary shopping street has been formed on a network such as the Internet, ^, there is no system that can measure naked eye vision and correct vision online in an eyeglass shop installed in this imaginary shop title. . 6 1223764 发明, description of the invention However, when trying to determine the power of the human eye, if the optical model of the eye is considered to be the same as the eyeball model, the optical error will be large. This can only be achieved by constructing optical models of each person's eyes one by one. 5 Using the conventional model eyes directly has the following problems. The model eyesight of s is based on the measured values of Europeans and Americans. For example, if you want to build a model that is close to the measured value of the living eyes of the Japanese, you cannot use the model eyes. For example, the radius of curvature of the cornea, f 幵 幵, is smaller than that of Europeans and Americans. 10 • Create a model based on the average of the measured values. According to the literature, the depth of the anterior chamber 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 structure of the water body is simply divided into two structures using an average refractive index of 15 emissivity. On the other hand, it is difficult to go to the ophthalmology or optician shop because of time and distance, etc. ^ People expect the emergence of a system for distance vision measurement through the Internet. The 20-inch is not the glasses or contact lenses currently worn. Compared with the previous ones, you can see the shape of the moon. In order to determine whether it is necessary to change the glasses or contact lenses? The determination of the words would be extremely convenient. In view of this, the main object of the present invention is to provide a system and method capable of determining the power of a spectacle / contact lens corresponding to the eyes of a person and the description of the invention.

Based on the above data, determine the bending position of the left and right temples 10 and register. 2. Based on the side photos of the user, measure the distance (L2) from the corneal vertex of the user's eye to the nose. The database management means 2005 records the average value of the left and right and manages it. Usually L2 is 12 mm. The glasses frame selection data input means 2 0 4 determines the nose of 15 glasses based on the measured values. Measure the distance to the ear (L3) based on the frontal photo of the user and the midpoint of the left and right interpupillary distance as the base point, and register this data by the database management method 2005. Based on the above-mentioned measured values, the spectacle frame selection information input means 2004 determines the opening angle of the spectacle legs, respectively, and registers them. To get the distance from the midpoint of the interpupillary distance to the ear, the interpupillary distance must be obtained first. However, because the eyewear sales service center 2002 cannot determine the interpupillary distance only based on the user's face image, the approximate value of PD can only be obtained by obtaining the distance (PD1) from the left side of the left eye to the left side of the right eye. 42 1223764 发明 、 Explanation of the invention * Yuyan's pupil-to-ear distance (L4) must also be positioned in advance. Because the pupil cannot be positioned based on the user's face image, the distance from the left ear to the right side of the left eye can be measured. (La) and the distance on the left (Lb), then calculate the distance from the pupil of the eye to the ear (L4). Measure the right eye in the same way.) The left and right opening angles of the spectacle frame are corrected by the following formula and Bend to adjust. PD / 2 + L4-L5

Ls is the front dimension of the spectacle frame (see FIG. 32). 4.

In this embodiment, by dividing the adjustment power of the eyeball of the examinee on the tension side or the relaxation side, it is possible to construct the extreme tension or relaxation of the eyeball. The state of the eye can determine the optical model of the eye 15 sphere located at the midpoint of the adjustment. The eyeball optical model is described. The eyeball optical model is an optical coefficient value model. As shown in Fig. 35, it is composed of a cornea, an anterior chamber, a crystalline lens, a vitreous body, and an omentum as an optical evaluation surface. The optical model of the eyeball is made up of the following optics: 20. Glasses and contact lens lenses: the curvature of the front of the lens is half # R1, the degree of refraction, the radius of curvature of the back of the lens R2, the cornea: the radius of curvature of the front R3, thickness, Refractive index, the radius of curvature of the German side R4. 49 1223764 发明, description of the invention, such as the room's degree of refraction, water and solar body.

In this embodiment, the value of the living body measurement data of the subject and the document data The value is based on the standard, and an eyeball optical model is constructed in advance as a standard type. 1〇 The following is an example of literature data applicable to the construction of optical models of eyeballs. (i) About the depth of the anterior chamber According to the Japanese Journal of Ophthalmology, Vol. 62, No. 11 (1958) Aizawa Kei's paper "Research on the depth of the anterior chamber", the relationship between the depth of the anterior chamber and age is ^ 5 8-15 years old 3.66mm 16 -30 years old 3.71 jobs * 31_51 years old 3.51mm 51-77 years old 3.18mm That is, the depth of the mortuary has increased from the beginning of adolescence to 20 ′ as the body develops, and it becomes the deepest in adulthood, which becomes shallower with the aging of the body in the future. tendency. (ϋ) About the axial length According to the paper of the Japanese Academy of Ophthalmology, Vol. 63, No. 7 (1959), "Study on the Real State of Myopia, Part 1", in the case of mild myopia, the axial length ik is near myopia. Deepening and getting longer 'are closely related. 50 1223764 发明 、 Explanation of the invention (iii) About the weight of the water crystal According to the book title · The eye, the publisher: New York, London,

Academic Press, author directory: Davson, Hugh, 1909, Graham, LT ·, Jr. The weight of the crystal is as follows: 5 20 years old-39 years old 174mg 40 years old-59 years old 204mg 80 years old-99 years old 266mg as the age increases And gain weight. (iv) About the diameter of the crystalline lens 10 According to "New Clinical Ophthalmology Book 3A" (edited by Ichikawa Hiroshi et al., Kanehara Publishing 1993), the thickness of the crystalline lens increases with age. An eyeball optical model constructed in advance using the values of the above-mentioned documents and the values measured by the living body is used as the initial eyeball optical model. & The beginning eyeball optical model focuses on the common eyeball characteristics when the age and the estimated lens power are the same. For all ages and the estimated lens power combination, it is not a starting ball model, with age as the vertical The axis is based on the approximate lens power as the horizontal axis, and an eyeball optical model is constructed in advance at the central value of the horizontal and vertical axis. If the vertical axis is divided into equal parts, and the horizontal axis is divided into N parts, an initial eyeball optical model is constructed. In other words, in the table with the age as the vertical axis 20 and the approximate lens power as the horizontal axis table, a starting ball optical model of the center value of each division is constructed in advance. In the following, some values of the optical elements of the initial eyeball model constructed in this embodiment will be described by way of example. W is an anterior chamber depth value from which correlation between age and estimated lens power is applied. 51 1223764 Rose, description of invention Table 1 \\ Estimated lens power in the low-age area 0 -2 -4 -6 18 (10-26) 3.58 3.75 3.87 3.98 36 (27-44) 3.42 3.57 3.70 3.80 47 (45-49) 3.10 3.25 3.37 3.44 55 (50-59) 2.94 3.10 3.23 —----— Λ Ο 1 j.

In this embodiment, based on the content of the above-mentioned file 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 eyeball optical model construction method is determined as shown in the following formula [Formula 1] z CY2 · + Α4Υ4 + Α6Υ64-Α8Υ8 15 In Formula 1, R is the reference spherical radius, ( : Yes 1/11, κ is eccentricity 52 1223764 发明, description of the invention. However, because the aspherical coefficient a4, VIII, 6, ..... of the i-th item can fully represent the shape of the lens, all values are 0. Simulation Each lens of the crystalline lens is made of a substance having a different refractive index at different locations. As shown in Figure 36, the refractive index nr (the distance from the center of each lens to the direction orthogonal to the optical axis in five directions is the refractive index) is shown in the following formula. [Formula 2 Πγ = nr0-An (r) In formula a, nr0 is the refractive index at the center of the lens, and Δ ^ ⑴ is the amount of refractive index corresponding to the decrease in distance from the center of the lens. [Formula 3]

An (r) = r2 / ks In Equation 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 literature data mentioned above. Looking at the center of the crystalline lens, the higher the near refractive index, as shown in Table 3, the closer to the center of the optical axis direction of the complex lens of the crystalline lens, the higher the value. Table 3 Lens Γ ~ ——- Refractive index profile f R5-R6 250 R8-R9 290 R11-R12 325 R13-R14 360 R17-R18 400 R19-R20 ^ ---- 360 R22-R23 ------ 300 ----------- 53 发明, description of the invention Therefore, for example, when the refractive index nr0 of the lens center of a lens having a refractive index distribution coefficient Ks of 200 is 141 °, the distance from the lens center to nm The refractive index is 1405, and it is 1.399 when it is 1.5 from the center of the lens. The construction method of the eyeball optical model is like adjusting the refractive index of the eyeball through tension or relaxation. Using the force coefficient α describing the distribution of the withering force per unit length of each lens that simulates the crystal, the optical elements are calculated to simulate the relaxation and tension of the crystal. In that way, the optical elements are decided. In this embodiment, the value of the distribution of the unit number α to change the optical elements of each lens is used as the refractive index distribution unit Ks, the aspheric coefficient κ, 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 -aD side (near point distance) or + aD (far point distance) side. 〇 here refers to the adjustment force, the value is expressed by 15 inverse distance from the reference point of the lens to the focus (in meters). At the time of attack, for the bD adjustment only on the relaxation side, the elements of the crystalline lens of the eyeball optical model use the power distribution coefficient α, by making the adjustment midpoint refraction ¥ distribution coefficient Ks aspheric coefficient κ and the value of the radius of curvature r (1 + q xb / a) is doubled, and an eyeball optical model that simulates a relaxed state is determined. On the other hand, when the bD adjustment is performed only on the tension side, by doubling the value of the optical 7L (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 1223764 发明, description of the invention Here is an example. The lens power of the near point of the optometrist is 疋 10.2D 'When the distance of the far point is · 0.2D, the lens power of the midpoint will be O.02D . 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 the cymbal diaphragm, the relaxation side, and The number Ks of refractive index knives on the tension side is the value shown in Table 4. 10 Relaxation side inflection Distribution coefficient 1 Tension side Distribution coefficient κ

The aspheric coefficient κ also has a value not shown in Table 399.9 5.

Fork-shaped female virginity verification method 4206 verifies the validity of the optical model of the eyeball at the adjustment limits at the midpoint, near-point side, and far-point 5 side. The eyeball optical element adjustment range determination means 4208 can determine the adjustment range of the eyeball located at the adjustment midpoint, and can represent an image of the eyeball optical model that determines the adjustment range of the eyeball located at the adjustment midpoint. The means for verifying the focusing performance of the eyeball optical model 4212 corresponds to the intended use, and verifies the light-gathering state of the eyeball optical model at three determined distances. The three distances are 0.3 meters (near distance) mainly 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 light 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 42 16 derives the visual sharpness scores of the examinee before and after correcting vision. 56 1223764 发明.

Myopia refers to the formation of parallel light entering the eye in front of the omentum when the glasses are not adjusted. The degree of myopia is represented by the reciprocal of the distance of the far point. The number of j is not expressed (for example, the distance of the far point = 50 cm, 1 / 0.5 = 2D). The relationship between the degree of myopia and vision is shown in Table 7. 15 Table 7 Naked Eye Myopia Correction Vision Naked Eye Vision ----------- Myopia Vision-~~~ --_ Corrected Vision 0.8 -0.5 1.2 0.07--5.0 1.2 0.5 -0.1 1.2 0.06 -6.0 0.9 0.3 -1.5 Γ 1.2 --0.05 '7.0 r 〇.7 0.2 -2.0 1.2 0.04 ~ 8.〇0.6 0.1 -3.0 1.2 0.03 -9.0 ---_ 0.5 Mild myopia (-4D), moderate myopia (n7D), intensity myopia ㈣ to -10D), the most intense myopia (more than _iod) The treatment of myopia is to wear a suitable concave lens. 20 The degree of hyperopia, the type of hyperopia, and the treatment method of hyperopia are registered in Far 59 1223764 Kan, Invention Description Vision Information Database and managed. The so-called hyperopia refers to the parallel light entering the eye in the omentum without any adjustment of the eye. Rear imaging. The types of π hyperopia are shown below. Mild hyperopia (+ 4D), moderate hyperopia (up to + 7D), and intensity hyperopia 5 (+ 7D). Hyperopia is treated with suitable convex lenses. The degree of astigmatism, the type of astigmatism, and the method of treatment are registered in the astigmatism information database and managed. The so-called astigmatism means that the parallel rays of light entering the eye are not imaged at one point without any adjustment of the eye. The types of astigmatism are shown below. 10 Positive astigmatism (unevenness in the inflection plane is symmetrical). Incorrect astigmatism (different curvatures in the same meridian, not imaging). The treatment of astigmatism is shown below. Unisex astigmatism (with appropriate cylindrical lenses). Refolding astigmatism (wearing cylindrical lenses and spherical lenses) 15 Incorrect astigmatism (wearing contact lenses) In the relationship between age and the adjustment power of the eyeballs, for example, as shown in Figure 37, the average corresponding to each age The regulatory power is recorded and managed. In the original eyeball optical model database, an eyeball optical model in which the vertical axis is the age and the horizontal axis is the approximate lens power 'was calculated in advance at the center of each axis. Therefore, if the vertical axis is divided into M divisions and the horizontal axis is divided into N divisions, there are M × N initial eyeball optical models that are recorded and managed.

The visual image database records and manages the visual image of the examinee before and after correction and the sharpness record Q. Next, a method for measuring vision by the long-distance vision measurement system 4010 will be made 60 1223764 发明 Description of the invention. First, the measurement of naked eye vision will be described. User customer 400 1-Connects to the glasses ordering sales service center 4002 and sends 1] 〇 number input screen as the user authentication screen. The user identification card is a screen that prompts the input of user authentication information. The user customer 4001 receives and displays the user authentication day and day, enters the user authentication information, and sends the fish to the eye sales service center 4002. User authentication information includes information such as pass codes and user IDs. The glasses order sales service center 4002 receives user authentication information, and based on this, it uses the database management means 4232 and the user information management means 4230 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. The user customer 4001 receives the service type screen and displays it. Next, on the service type screen If you want to measure the naked eye vision, the user only needs to click "nude eye vision measurement". 20

Here-the 'wearing condition input screen will be sent by the glasses ordering and sales service center 4002 to the user customer through the global information network server 3G for the wearing condition. I want to wear glasses. The purpose of contact lenses (for example , Look at the near, distant, when driving, etc., when you want to wear and so on) and depending on the environment (usually in what range to see how many distance things are more, do you do more computer work at work, etc.). The glasses ordering sales service center sends the user information through the global information network server 30 and enters the written form. 61 1223764 发明, invention description User information input screen prompts the user to enter the user's personal information (user number, 1D, pass code, address, name, date of birth, etc.), purpose of use, far distance, far point Distance, age, anterior degrees, binocular vision at anterior degrees, left-right balance at anterior degrees, 5 years of use of front glasses, type of contact lenses (when used with glasses), hope for correction of vision, presence or absence of eyes Data on diseases. Next, the eyewear ordering and sales service center 4002 sends naked eyesight measurement daytime to the user customer 4001 through a global information network server. First, the astigmatism index shown in Fig. 38 will be displayed, and the visual acuity will be checked while changing the distance within the range of 10 meters. The user covers one eye with his hand and looks at the daytime surface with the other eye. On the day-to-day vision of naked eye measurement, a portrait or target for single eye measurement is displayed. Next, the user fixed the head and neck and kept a certain distance from the surface of the naked eye. For example, hold your cheeks with your palms and place your elbows on the table. Then, the near-point distance is measured. The shortest distance between the eye and the screen when the eye can see the image on the screen is the near point distance. Next, the far point distance is measured. The eyes can see the image on the screen clearly. The longest distance between the eyes of the sun guard and the daytime surface is the far point distance. Measure the distance between the day and the eye horizontally with a ruler and enter it. Next, a method for determining the power of glasses and contact lenses will be described based on the flowchart shown in the figure. First, as the information about the state of the eye of the examinee, the near-point distance, far-point distance, wearing conditions, and the like are measured on the input hand 62 1223764 玖, invention description section 4202 through a global information network device, and Enter the age. The 5th week of the year, especially the elasticity of the crystalline lens, is related to the 'adjustment power' decreases with age (see Figure 37). The reason is that the elasticity of the crystal 5 body decreases with age, and it is difficult to change the meandering force in response to the change in distance. Although the adjustment power decreases with age, it can be assumed that people of the same age have approximately the same adjustment power. Secondly, based on information such as age, near point distance, and far point distance, 10 = determines the approximate lens power of the lens ‘contact lens’. You can calculate the adjustment midpoint position based on the degree of different lens powers. For example, suppose the distance at the far point is calculated and the distance at the near point is 25 cm. The lens power required for correction at the far point is m, and the lens power required for correction at the near point is _4 cents. The estimated lens power of 15 is (-1-4) /2=-2.5D. The distance at this time 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. 20 "The starting eyeball optical model is an eyeball optical model created in advance with the riding age on the vertical axis and the approximate lens power on the horizontal 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, the age axis is used as the vertical axis (for example, 5 years old up to 20 years old is 63 1223764 玖, invention description, 20 years or older is used as 10 years old units), and the approximate lens power is used as the horizontal axis (for example, In the table of L0D), the initial eyeball optical model of the combination of the intermediate values of each division (for example, 35 years old) is necessary to correct the amount of correction of the lens power of _25 [). As long as the specific age of someone, the estimated lens power, you can choose one from the MxN starting eyeball optical models. The selected initial eyeball optical model is used as an initial value when the optical system is automatically designed for the purpose of constructing the person's inherent eyeball optical model. Compared with the optical and automatic design processing using a separate starting eyeball optical model that does not pass through age and approximate lenses, the starting eyeball optical model has a fast convergence of automatic design processing, can shorten the processing speed, and can be used on the Internet. It has high reliability (such as the optical elements with the highest condensing state). Here, the method of determining the initial eyeball optical model will be described. (1) A group of combinations is assumed from the distinction of the degree of lens power and the distinction of age. Regarding the adjustment of the midpoint position as the median state of the person's adjustment function, it is assumed that the estimated lens power is to correct the tortuous force of the eye of the person in the neutral state, and the adjusted midpoint position is calculated based on the estimated lens power. (2) Using this initial eyeball optical model, let the light enter the eyes from the adjusted midpoint position, evaluate the light condensing state on the light retina, and make the optimal light condensing state. The elements change to determine the best solution (optical elements). This is the same as "the construction of an optical model of the eyeball of a person at the midpoint of the adjustment 64 1223764 发明, description of the invention processing". ⑺Using the relationship table of the average adjustment range corresponding to age, at the assumed age, as the age-specific average adjustment range, derive the eye tortuosity at the upper and lower limits of the adjustment range, and then derive the near point distance of 5 Far distance. ⑷ Check the initial eyeball light at the adjustment limit (near point side) and far point side: pull-type femininity. If it is appropriate, determine the initial eyeball optical model. If the light concentration is not good, return (3 ), Riding and then processing. (5) Perform the above processing on M × N, and make M × N initial eyeball 10 optical models. (6) For the optical elements of the MxN eyeball optical model, the overall examination is centered on the contradiction, the connection, and the 'besson', and the correction is made. Try again from (2) as appropriate. Dou inch is the decision of the refractive index distribution of the crystalline lens. Next, 'construct the eyeball optical model of the examinee located at the adjustment midpoint. Model 0 The construction of the eyeball optical model located at the adjustment midpoint is based on the automatic design and calculation of the optical system.' The state 20 evil becomes the best state 'automatically determines the human eyeball optical elements. The automatic design calculation of the optical system here refers to the automatic decision-making process of optical elements through the use of lens automatic " ray tracing and program counting. As a representative example of this second-hand method, there is the Durnpecj Least Squares Method. In this embodiment, the method is used to perform the correction processing of the moving difference from 65 1223764 发明 and the invention to maximize the recording state. good. ίο 15

The automatic correction correction process is to meet the final performance conditions (here, 'Qing adjusts the starting point of an infinitely small point object, for the pupil diameter of the eyeball optical model, the complex light changes the incident height into the light, Perform light tracing so as to achieve a state of forming a point on the omentum and achieve a good light-condensing performance.) The optical elements-edges are still slightly changed in order to shift the positions of the reaching points on the omentum. The amount of self-multiplication is minimized and corrected. X, in the case of spherical lenses, when the radius of curvature of the lens and the interval between the lenses are changed in the opticians of the eyeball optical model, and in the case of aspherical lenses, 'the radius of curvature of the reference spherical surface of the lens and the aspheric surface Countless changes occur because the shrinkage of the solution has been judged to proceed rapidly. In this embodiment, in various situations, the above-mentioned optical elements are constituted for automatic error correction. Secondly, according to the model suitability verification method 4206, the validity of the eyeball optical model of the adjustment limit (near point side) was checked.

The properness check is to increase the tortuosity of the eyeball only under the adjustment power possessed by the human eyeball, and to automatically design and calculate according to the optical system to confirm a good light-condensing state. Here, the so-called increase of the tortuosity of 20 eyeballs only under the adjustment power of human eyeballs means the following. Assuming that the distance between the far point is 1 meter (-i.OD) and the distance between the near points is 25cm (_4〇D), the adjustment of the midpoint position is 40cm (-2.5D), compared with the adjustment of the midpoint position. It is necessary to increase the amount of U.5D correction. In order to enhance the -1.5D equivalent eyeball tortuosity, as described above, the optical elements of the 66-nano, dry-type optical element of the invention are enhanced by a xb times, while controlling the light to the boundary condition of automatic design. From a small object with a helmet limit at a distance of 25 cm from the near point, the pupil diameter of the eyeball optical model (for example, 3 mm in diameter) 'changes the incident height of a plurality of rays to make it enter the light, and traces the rays into, Make it a point on the omentum to change the optical elements, and implement the automatic design of the optical system. i If the result reaches a state of condensing to a point, it can be judged that the simulation of the optical model of the adjustment limit has been successful, and the optical model of the eyeball of the person at the midpoint of the adjustment is appropriate. Next, through the model validity verification means 4206, the validity of the eyeball optical model at the far-end side of the joint limit was checked. The properness check is to reduce the tortuosity of the eyeball only under the adjustment power possessed by the human eyeball, and to automatically confirm the good light-condensing state based on the automatic design calculation of the optical system. The so-called reduction of the tortuosity of the eyeball only under the adjustment power possessed by the human eyeball is as follows. Assume that the far-point distance is ^ claw 1 · 0 D) 'The near-point distance 隹 is 2 5 cm (-4 · 0 D), and the adjustment mid-point position is 40 cm (-2.5D). Compared with the point position, it is necessary to reduce the eye tortuosity equivalent to the correction amount of + 1 · 5 D. As mentioned above, in order to reduce the eye tortuosity equivalent to + 1.5D, the optical elements of the eyeball optical model must be increased by (1-a xb / a) times, while controlling the realm of automatic design of the optical system, the On an infinitely small point object with a distance of 1 m, the pupil diameter (for example, 3 mm in diameter) of the optical model of the eyeball changes the incident height of a plurality of light rays to make it enter the light, and the light rays are traced, and the invention is traced. Reach the state where the junction image is a little on the omentum, change the optical elements, and implement automatic design of the optical system. If you look at the state of focusing on one point, you can think that the simulation of the optical model at the adjustment limit state is successful, and you can judge that the optical model of the person's eyeball at the midpoint of the adjustment is appropriate. Furthermore, according to the model suitability verification means 4206, the validity of the eyeball optical model outside the adjustment limits of the near point side and the far point side, that is, outside the adjustment range of the eyeball, was checked. Next, through the eyeball optical element adjustment range determination means 4208, 10. For the eyeball optical model located at the adjustment midpoint position, determine the eyeball optical element adjustment range. The adjustment of the optical elements is determined as follows.

According to the model suitability verification means 4206, the eye spot stop λ on the f 15 point side, the transport point side, and λ: 丨 丨 a λ, 丨 &68; 2323764, the description of the invention is determined by the process of checking. … If the above privacy is confirmed, the eye adjustment corresponding to the object distance can be simulated. In other words, according to the means for generating an optical model image of the eyeball 10, the determined optical model image of the eyeball, such as the generation of a cross-sectional view of the eyeball, can be described in one piece. Thirdly, according to the eyeball optical model light-condensing performance verification means 4212, the light-condensing performance can be calculated and verified with the three distance adjustments of the naked eye state of the examinee. 10 According to the model suitability verification means 4206, the process of checking the suitability of the eyeball optical model located at the adjustment limit (near point side, far point side), and the same as this process, to obtain the distance from the adjustment from the adjustment The amount of tortuosity of the eyeball at the point position is increased or decreased, and the automatic design of the optical system is implemented while controlling the limit conditions of the automatic design of the optical system. 15 The 14 optical elements obtained represent the state of the eye when the virtual eyeball is focused. Iterative calculations are performed until the condensing state cannot become better, and the final optical elements are regarded as the optimal condensing state of the object distance. For the evaluation of condensing performance, from the infinitely small point object 20 located at a certain distance, the pupil diameter (for example, 3 mm in diameter) of the eyeball optical model was used to uniformly disperse hundreds of light rays into the light, Ray tracing, calculating where the omentum is imaged. For the evaluation of the degree of blurring, the spatial frequency characteristic (OTF) is calculated based on the two-dimensional transformation of the intensity distribution of the point image on the omentum, and the image is evaluated. 69, invention description 3 distances called 3 distances.疋 The choice of observation method may change greatly. Observation (close range), 0.5 ~ 0.6m (middle distance), 5m (distant distance). When the object is farther away, Ύ checks the focusing performance through the adjustment force at the distance of the transport point. Closer point of object distance% ", I τ ′ is obtained through the adjustment force at the near point distance

Check the focusing performance. When the object distance is between the near point and the far point, only the adjusting force of the point A changes the eye tortuosity and checks the light focusing performance. According to the method for verifying the focusing performance of the optical model of the eyeball, the person calculates and verifies the focusing performance of the three distances following the bridge of the pair of glasses and contact lenses.

That is, the actual lens (the radius of curvature of the 刖 plane of the lens, the radius of curvature of the plane, and the lens with a known glass refractive index) is placed in front of the eyeball optical model, and the same calculation is performed as in the case of naked eye-like evil light. . Determine the appropriate imaginary lens based on the estimated lens power and wearing conditions, and perform optical simulations on the light-condensing performance when wearing glasses and contact lenses. Further, when the balance of the sharpness scores at three distances is not good, the power of the lens is slightly changed, and the optical simulation is performed again. (A) Calculation of the sharpness score Next, based on the freshness score generation means 4206, the optical elements of the eye within the adjustment force range are changed. Optimum state of light-condensing performance 70 1223764 发明 Description of the invention ′ Calculate the score of freshness at this time. The sharpness score is calculated by evaluating the light-condensing state. From an infinitely small point object at a certain distance, aiming at the pupil diameter of the optical model of the eyeball (for example, 3mm in diameter), hundreds of rays are made uniform, scattered into five places, and ray tracing is performed to calculate the ray tracing on the omentum. Where is the imaging ·. The value obtained by transforming the two-dimensional intensity distribution of the point image is called the spatial frequency characteristic (OTF). If the intensity distribution on the omentum is investigated, the degree of blurring can be evaluated. The so-called space frequency is a value indicating how fine the stripe pattern is, and is defined by the number of 10 stripes per unit length. In the visual system, it is expressed by the number of stripes at each angle of view. For example, when the interval of the stripes is w (degree), u = a / w (CyCies / deg). The value of ~ used to determine the degree of blur can be determined from the decomposition of the omentum, and the sharpness score is calculated from the u value at this time. 15 The "*" person determines the recommended lens according to the selection method 42 1 8 of the film power. _ Then ’according to the visual § tolerance image generation means 2 14 to generate visual images of 3 distances after the recommended lens correction and before correction. That is, the method of viewing in the state of the naked eye and when wearing the recommended lens is suggested. In addition, the score of the sharpness of the previous 20 is indicated in the visual image (as shown in Fig. 41). (B) Generation or selection of visual images According to visual image generation means 42 14, three-distance images are prepared for high-resolution photography. For this image, smooth the size of the pixel unit N × N, and take care of it. 发明, description of the invention Blur portrait, the degree of blur is N (minimum 3), repeated care, can be adjusted through the number of processing times. After considering the processed image, blurring degree is determined by spatial frequency analysis, and the correspondence of the sharp 5 degree score obtained by calculating the sharpness score of the preamble (A) is obtained. Prepare several day images that correspond to the sharpness score. At the same time, a score corresponding to an image subjected to a specific smoothing process for the prepared image is calculated. For example, if the score value is calculated by calculating the score of the sharpness in the preface (A), then 10, according to the score value, either call up the corresponding portrait, or take care to make the resulting portrait and sharpness score match and give Means. Further progress' According to the visual image generation means 4214, the lens is exchanged, and the image of the visual method at 3 distances is suggested so that it can be compared. In other words, the power of the lens is changed, and the optical simulation in the state of wearing glasses and contact lenses is performed. Then, the optical elements in the adjustment range of the eyeball are changed to obtain a state in which the light focusing performance is excellent, and the sharpness score at this time is calculated. If the freshness score of a specific lens power according to the lens power selection means 4218 has been calculated, the data can be used directly. 20 As mentioned above, Shenxin 4002, an ordering and sales service for eyeglasses, sends the generated image of the viewing method to the customer 4001 as a user through the global information network of 4220. In addition, the visual acuity measurement result prepared separately is sent to the user's customer and displayed on the screen of the visual acuity measurement result. Conscious vision test 72 1223764 发明, description of the invention The final result includes the following content. DIST (represents distance power), READ (represents near power), spH (represents spherical power), CYL (represents astigmatism power), AXIS (represents axis), PD (represents interpupillary distance). 5 In addition, the distance power and the near power both indicate the right eye and the left eye. The current computer optometry is to select the lens with the best distance vision. After the optometry, wear it continuously and adjust the power of the selected lens with reference to the wearing situation. According to this invention, since a sharpness score can be calculated through a viewing method with a complex distance of 10 when wearing a certain lens, the balance of the viewing methods at three distances is studied with reference to the wearing conditions inputted initially, Can improve the best degree of comfort without wearing. In other words, the current status is a conscious check to confirm the actual "wearing condition". Although it is necessary, it can be omitted here. Choose the most suitable for online shopping. 15 In addition, in the embodiment, an eyeball optical model of the adjustment center of the examinee is constructed. Not limited to this, an eyeball optical model of an arbitrary point between the near-point distance and the far-point distance of the examinee may be constructed. In this case, according to the adjustment position where the eyeball optical model is constructed, it is possible to construct an eyeball optical model on the near- or far-point-side adjustment limit by allocating the adjustment force on the tension side or the retardation side. In the above state of implementation, as an 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 pieces, and the approximate lens is divided into N pieces. Based on the central value of the nuclear division, a pre-built structure is used. The initial eyeball optical model is not limited to this, and the eyeball optical model most suitable for the data input by the inspected 73 1 ^ 23764 玖 and the inventor may be used as the initial value of the automatic optical design process. In this case, the eyeball optical module corresponding to the state of the eyeball of the examinee is type 5 according to the age of the examinee and the estimated lens power calculated, based on the difference between the central value of the difference and the difference. Used as an initial value. According to this, using the start-eye optical model constructed in advance from the central value, it is possible to perform automatic error correction in less time than automatic error correction. Furthermore, in this embodiment, the value of w using fuzzy judgment can be determined from the decomposition of the omentum. Although the sharp 10-degree score obtained from the value at this time is calculated, it is not limited to this and can be calculated by other methods Sharpness score. For example, if the spatial frequency of the incoming light is changed and the OTF value is 70%, find the value of the spatial frequency at this time. At this time, the spatial frequency of the incident light rays is changed within a certain range within a certain period of time, the minimum spatial frequency is 0, and the maximum spatial frequency is 100. By obtaining a spatial frequency of TF value of 15 70%, we can obtain Sharpness from 0 to 100. In addition, in the implementation state, the inspected person can view the visual image generated by the visual image generation means 216 as it is, but it is not limited to this. After correcting the degree of blurring of the image, the inspected person can also be inspected. Prompt image. This is because when a person sees an object, a landscape, and similar objects, a landscape 20, even if it is a blurred image, from the person ’s memories of the object, the landscape, and the landscape that has only been seen once to supplement the image information I feel the visual image tends to be seen clearly. Therefore, specifically, for most of the examinees, the difference between the image generated by the visual image generation means 216 and the blur degree actually perceived by the examinee is verified. Created based on the verification results 74 1223764 发明, description of the invention The correction coefficient table is used to correct the degree of blurring based on the correction coefficient table. Based on the correction result, the subject is presented with an image. again. In the case of Xuan Λ%, the examinee used the naked eye vision measurement screen 'actually measures the distance that can be away from the beginning of the screen, and turns in the data of the far point distance to calculate the approximate lens power. Calculate the far point distance. In Fig. 3, each of the far-distance vision calculations from the above § far-distance vision calculation shows other implementations of the astigmatism axis, far-sight vision measurement, and near-point distance measurement. First, it is shown that in order to obtain the examinee's attribute input screen of the examinee's 10 attributes (S10), the obtainment of the examinee's input attributes is stored as the examinee's data (S12). The attributes of the subject include personal information such as age, gender, and height, as well as information on the wearing conditions of the main use place for glasses and contact lenses. Fig. 44 is an example of a display screen when acquiring personal information, and Fig. 45 is an example of a display screen when acquiring wearing conditions. Here, "reading" and "desktop work", which are intended to determine the wearing conditions, are for close range, "personal computer" is for medium distance, and "driving" is for long distance use. Next, the astigmatism axis determination table (S14) for astigmatism axis determination is shown, the selected orientation of the subject is obtained, and the selected orientation data is saved (S16) 2O. Fig. 46 is an example of an explanation screen for determining the astigmatism axis, and Fig. 47 is an example of the astigmatism axis. As shown in the figure, the astigmatism axis determination table is composed of a plurality of parallel lines, and is composed of linear groups in four directions of 45 degrees, 90 degrees, 35 degrees, and 80 degrees. The subject has astigmatism, because there is a clear visible position and it is difficult to see 75 玖, invention description 疋 azimuth, prompted to click on the range of different viewing methods. In this way, the different orientations of the viewing direction are chosen because the direction of astigmatism corresponding to the distance between objects can be clearly seen. The astigmatism may be changed if the orientation that can be clearly seen from the beginning is set. Axis judgment may be wrong. Therefore, the present invention does not determine the main axis of the astigmatism axis at this stage, and it is cleared by seeking the distance of the far point later. ’There are also bright subjects, because in principle they should look uniform in all directions

Same, treat all subjects who are the same or do not understand as no astigmatism, and perform the level measurement with the following measuring instrument.

Astigmatism axis judgment table, the background color is the color recording, the color of the line is black, the line field is 2 deniers, and the line width is 3 days. Since the background color is white, the brightness is not clear, the pupils are narrowed, the depth of the written world is deepened, and there is a problem that the viewing method of the four layers is poor. The green system suitable for the eye is used to suppress the brightness. The color of the line is based on the results of an eye test performed on a large number of subjects. The line width takes into account that when the screen is a CRT, the electric shock grabs the focus and blurs the phenomenon. Because there is only one day, the horizontal, vertical, and oblique viewing methods will differ. The minimum is 2 pixels. For the determination of astigmatism, if the distance to the table is very short, the astigmatism axis will change, and erroneous determination may occur. Therefore, setting the line width 20 can identify the distance from lm to the gap between the lines. Visual acuity of 1.0 (1 minute of viewing angle) is the ability to recognize an incision of 0.29mm at a distance of lm. Using a 14-inch LCD screen or a Π-inch CRT is equivalent to approximately 1 day. Therefore, two-day voxels are equivalent to about 0.5 vision. Depending on the eye examiner's need for glasses, the interval is further extended to use three pixels. 76 1223764 发明 、 Explanation of the invention The orientation of the astigmatism axis is 4 directions, because even in the 4 directions, the glasses and contact lenses can be selected in a practical manner. Because it is the subject's own judgment, it is necessary to make the judgment as easy and error-free as possible. Next, in order to measure the selected orientation selected by the subject, a visual acuity measurement table indicating the selected orientation (S18) is obtained, and the visual recognition limit selected by the subject is obtained and stored in the first visual limit data (S20). Fig. 48 is an example of an explanation screen for far-sightedness measurement, and Fig. 49 is an example of far-sightedness measurement daytime surface. As shown in the figure, the visual acuity measurement table is a linear shading image composed of 3 black lines and 2 self-lines with a certain line width. Corresponding to visual acuity, it is a complex chart showing the change of line width from ^ to 10 segments (from丨 〇 stage to 20 stage). In response to this, the subject was prompted to click on the three smallest symbols that could be seen. 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 vision at a distance of 15 points. This is because the length of the arm is approximately proportional to the height. Based on the height data input in advance, it is possible to predict the difference between the subject and the eye chart. Distance. # Nothing, because the subject does not need to measure the distance from the computer screen, and there is no need to adjust the screen display size, which can be easily measured. Similarly, in order to measure the far-sightedness of the selected orientation and orthogonal 20 orientations selected by the subject, a visual acuity measurement table showing the selected orientation and orthogonal orientation '(S22) is obtained, and the visual recognition limit selected by the subject is obtained and saved In the second visual limit data (S24). Next, in order to measure the near point distance of the azimuth selected by the subject, the near point distance measurement table (S26) showing the selected azimuth is selected. The near point 77 1223764 entered by the subject is stored. In the point distance data (S28). Fig. 50 is an example of a screen for explaining the near-point distance measurement, and Fig. 51 is an example of the 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. According to the description of the screen, for the subject, first try to get as close as possible to the daytime surface, and then away from the computer daytime surface, until the three black lines can be seen clearly. In addition, the near-point distance measurement table is visually recognized near the computer, and a thin line is used as compared with the visual acuity measurement table described above. However, because of the difference in resolution due to different ages, young people use thin lines, and "old people use several thick lines." 10 Similarly, in order to measure the near-point distance of the selected orientation and the orthogonal orientation selected by the subject, the near-point distance measurement table (s30) indicating the selected orientation is stored, and the near-point distance input by the subject is stored in the first place. 2 Near-point distance data command (S32). Secondly, the far-point distance is obtained from the first visual limit data, the near-point distance data, and the subject's 15 limit data. Stored at the 1st farthest distance (S34). Similarly, the far-point distance is obtained from the second visual limit data, the second near-point distance data, and the subject's limit data, and is stored in the second far-point distance data (S36). The new network, which most of the examinees studied, was carried out on the 20th channel. Figure 52 shows the composition of the new network using the far-point distance calculation as shown in the figure. The input layer consists of the far-sightedness of stage I and the near distance of j-stage. The age and sex are used as the number because the subject's follow-up tone changes accordingly. In addition, the height is as described above. The distance between the subject and the daytime surface is expressed by the length of the arm, and the body is proportional to the length of the arm. 78 1223764 发明 Description of the invention High substitute parameter. As a learning method, the background method is adopted. Here, the near-point distance of the input parameter and the far-point distance of the calculation result are all converted to the power of the lens in units of m, which are converted into the reciprocal of the distance D to be treated. 5 In addition, the generation of the new network, the selection of the orientation of the astigmatism axis, and the selection of orthogonal orientations of the two independent learning models are calculated individually. In addition, because the method of viewing the daytime surface changes with the type of screen, depending on whether the screen is a liquid crystal or a CRT, a new network with independent learning is used for calculation. In addition, in the embodiment described above, the approximate lens power is calculated from the far point distance, but it is not limited to this, and the approximate lens power may be determined from the input far-sightedness. In this case, a correspondence table prepared based on statistical data and memorizing the approximate lens power corresponding to the value of far-sighted vision is used. 15 Based on this correspondence table, the approximate lens power is determined. In the above-mentioned embodiment, in the process of determining the power of the lens, the eyeball optical model of three distances of the short distance (0.3m), the middle distance (0.5 to 0.6m), and the long distance (5m) was verified. The light-condensing performance is not limited to this, and the light-condensing performance may be verified at a distance other than these. It is not necessary to verify the light-concentrating performance of near-distance 20, middle-distance, and long-distance. The possibility of use is based on this invention, because the eyeball optical model inherent to the examinee is constructed, which can determine glasses and contact lenses that match the power of each person's eyes. 0 79 1223764 FIG. 1 is a diagram showing a system configuration example of a glasses / contact lens selection system according to an embodiment of the present invention.
