Description

Technical Field

[0001] This invention belongs to the field of lens fitting technology, specifically relating to a positioning device for auxiliary marking of lens frames and a method for fitting progressive lenses. Background Technology

[0002] Progressive lenses are a type of multifocal lens whose refractive power gradually transitions from the distance vision zone at the top of the lens to the near vision zone at the bottom, with a progressive transition zone in between. The fitting requirements for progressive lenses are much higher than those for ordinary single vision lenses, requiring precise measurements of parameters such as monocular pupillary height, monocular pupillary distance, tilt angle, lens-to-eye distance, and near pupillary distance.

[0003] However, existing progressive lens fitting equipment is limited in function, measuring only parameters for the distance or near vision zones on a single device. It cannot simultaneously measure multiple visual parameters of the human eye, making operation cumbersome and affecting accuracy. Furthermore, traditional measurement equipment cannot combine the actual parameters of the frame with the user's wearing habits for the production of actual progressive lenses. Production often directly uses values ​​from generic frames and average user data, failing to provide personalized manufacturing for individual frames and different users. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies in the prior art and provide a positioning device for auxiliary marking of eyeglass frame lenses. The positioning device for auxiliary marking of eyeglass frame lenses can obtain various data of the distance and near vision zones of progressive lenses, which is beneficial for personalized customization for different eyeglass frames and different wearers' usage habits, thereby improving the accuracy of progressive lens fitting and wearing comfort.

[0005] This invention is achieved through the following technical solution:

[0006] A positioning device for auxiliary marking of eyeglass frame support includes an eyeglass frame holder, two sliding test blocks, and a verticality marking device. The eyeglass frame holder includes a horizontal bar and two vertical bar assemblies, with the two vertical bar assemblies respectively disposed at both ends of the horizontal bar. The two sliding test blocks are movably disposed on the vertical bar assemblies, and the two sliding test blocks can move vertically along the extension direction of the vertical bar assemblies and horizontally. Each sliding test block includes a high-beam test slider and a near-beam test slider arranged sequentially from top to bottom and connected to each other in the vertical direction. The high-beam test slider is provided with a cross mark, and a high-beam pupil positioning hole is provided through the intersection of the cross mark. The near-beam test slider is provided with a near-beam pupil positioning ring and a horizontal marking groove communicating with the positioning hole. The horizontal marking groove is disposed above the positioning hole and tangent to the positioning hole. The verticality marking device is disposed in the middle of the eyeglass frame holder.

[0007] This invention provides a positioning device for auxiliary marking of eyeglass frame support lenses. Two sliding test blocks are movably disposed on a vertical rod assembly. The two sliding test blocks can move vertically along the extension direction of the vertical rod assembly and horizontally. The high-beam zone test slider is provided with a cross mark, and a high-beam zone pupil positioning hole is provided through the intersection of the cross mark. The near-beam zone test slider has a near-beam zone pupil positioning ring and a horizontal marking groove communicating with the positioning hole. The horizontal marking groove is disposed above the positioning hole and tangent to it. The wearer installs the eyeglass frame with the lens to be installed onto the positioning device for auxiliary marking of eyeglass frame support lenses. When obtaining the parameters of the high-beam zone, the wearer looks straight ahead. A verticality marking device is used to ensure that the pupil positioning hole of the far-light zone on the positioning device worn by the wearer is parallel to the ground. At this time, by moving the sliding test block, the wearer's pupil is aligned with the pupil positioning hole of the far-light zone. Marking is made on the frame support through the pupil positioning hole of the far-light zone to obtain the position of the fitting point of the far-light zone, the pupillary height of one eye, and the pupillary distance of one eye. When obtaining the parameters of the near-light zone, the wearer is in a reading posture with their head down. At this time, by moving the sliding test block, the wearer's pupil is aligned with the pupil positioning ring of the near-light zone. The positioning device used for auxiliary marking on the frame support is removed. Marking is made on the frame support through the pupil positioning hole of the near-light zone and the horizontal marking groove to obtain the position of the near-light zone, the inward displacement of the near-light zone relative to the far-light zone, and the length of the asymptotic channel. This invention uses a positioning device for auxiliary marking of the lens frame to obtain various data on the distance and near vision zones of progressive lenses. This facilitates personalized customization for different frames and different wearers' usage habits, improving the accuracy of progressive lens fitting and wearing comfort.

[0008] Furthermore, the high-beam zone testing slider is a transparent testing slider, with cross marks on both sides. The high-beam zone pupil positioning hole penetrates through the transparent testing slider. Because the high-beam zone testing slider is transparent and has cross marks on both sides, when acquiring high-beam zone parameters, the wearer looks straight ahead, and the observer is positioned opposite the wearer. When the cross marks on both sides of the transparent testing slider are aligned, combined with the perpendicularity marking device, it indicates that the wearer's line of sight is level, which helps improve the accuracy of acquiring high-beam zone parameters.

[0009] Furthermore, the vertical rod assembly includes a vertical track, which is vertically disposed on the horizontal rod; the two sliding test blocks are respectively movably disposed on the vertical track in the vertical direction, and can move horizontally on the vertical track.

[0010] Furthermore, the verticality marking device includes a verticality display and a verticality pointer. The verticality display is vertically positioned in the middle of the horizontal bar. An angle scale is provided at the lower part of the verticality display, with a vertical mark on the scale. The reading on the angle scale gradually increases outwards along the horizontal bar. One end of the verticality pointer is rotatably mounted on the verticality display, and the other end extends towards the angle scale. When acquiring parameters for the high beam area, the wearer looks straight ahead, and the verticality pointer points vertically downwards. When the verticality pointer coincides with the vertical mark, it indicates that the wearer's line of sight is at eye level.

[0011] Furthermore, the vertical rod assembly also includes a vertical fixing rod, which is vertically fixed to the horizontal rod. The vertical track is rotatably disposed on the horizontal rod and can rotate relative to the vertical fixing rod to form a certain angle, or rotate until it is in contact with the vertical fixing rod. When obtaining parameters of the far-light zone, the wearer looks straight ahead. At this time, the vertical track is rotated towards the outside of the horizontal rod so that the vertical track forms a certain angle with the vertical fixing rod, until the verticality pointer coincides with the vertical mark, indicating that the pupil positioning hole of the far-light zone of the positioning device worn by the wearer is parallel to the ground. Keeping the wearer in a straight-ahead state, the vertical track is rotated in the direction towards the inside of the horizontal rod until the vertical track is in contact with the vertical fixing rod. Since the verticality pointer remains vertically downward during the rotation and the angle scale of the verticality display rotates synchronously, the angle formed between the vertical track and the vertical fixing rod can be measured by observing the reading of the verticality pointer. This angle is recorded as the forward tilt angle of the frame.

[0012] Furthermore, a vertically moving block is provided on the vertical track, and the vertically moving block can move along the extension direction of the vertical track; the sliding test block is fixedly connected to the vertically moving block, and the sliding test block is positioned relative to the vertically moving block on the inner side near the horizontal bar, and the sliding test block and the vertically fixed rod are located on the same plane. The fixed connection between the sliding test block and the vertically moving block enables movement on the vertical track; the positioning of the sliding test block relative to the vertically moving block on the inner side near the horizontal bar, and the positioning of the sliding test block and the vertically fixed rod on the same plane, allows the sliding test block to be as close as possible to the support piece on the frame.

[0013] Furthermore, the positioning device for auxiliary marking of the eyeglass frame support also includes a horizontal moving device, which protrudes from the side of the vertical rod assembly facing outwards. The sliding test block is connected to the horizontal moving device, which drives the sliding test block to move horizontally and can move until it abuts against the edge of the vertical rod assembly. The sliding test block and the vertical rod assembly are located on the same plane. The horizontal moving device drives the sliding test block to move horizontally and can move until it abuts against the edge of the vertical rod assembly to increase the range of motion of the sliding test block in the horizontal direction and avoid interference from the vertical moving block, which would prevent the test from being performed according to the wearer's specific face shape.

[0014] Furthermore, the vertical center line of the near-vision pupil positioning ring is offset towards the center of the frame relative to the vertical center line of the far-vision pupil positioning hole. In the use of progressive lenses, the wearer's pupil position differs in the near and far vision zones. To accommodate different usage scenarios, the near-vision pupil positioning ring is offset towards the center of the frame relative to the far-vision pupil positioning hole, minimizing the need for adjustment of the sliding test block during testing and reducing operation time.

[0015] Furthermore, the positioning device for auxiliary marking of the frame support also includes a support clamping component, a lens eye distance measuring device, and a lens angle measuring component; one end of the support clamping component is rotatably disposed on the horizontal bar and located inside the vertical bar assembly; a support clamping space is formed between the support clamping component and the vertical bar assembly, and the support clamping component can be opened or closed relative to the vertical bar assembly; the lens eye distance measuring device is disposed at one end of the horizontal bar; the lens eye distance measuring device includes a lens eye distance measuring ruler and a horizontal fixing frame, the lens eye distance measuring ruler is movably disposed on the horizontal fixing frame and extends from one end of the horizontal bar in a direction close to the inside of the horizontal bar; the lens angle measuring component is disposed at the other end of the horizontal bar, and the lens angle measuring component includes a horizontally disposed lens angle measuring ruler. The support clip and the vertical rod assembly form a support clip clamping space. The support clip can be opened or closed relative to the vertical fixed rod to clamp the eyeglass frame. The lens-to-eye distance measuring scale is movably mounted on the horizontal fixed frame and extends from one end of the horizontal rod in a direction close to the inside of the horizontal rod. When testing the wearer's lens-to-eye distance, the lens-to-eye distance measuring scale is adjusted so that its front end is tangent to the front end of the wearer's cornea. At this time, the distance between the front end of the lens-to-eye distance measuring scale and the inside of the lens can be obtained, thus obtaining the lens-to-eye distance. The lens angle measuring component is mounted on the other end of the horizontal rod. The lens angle measuring component includes a horizontally mounted lens angle measuring scale. When the eyeglass frame is fixed on the horizontal rod, the observer can look down at the scale value of the lens angle measuring scale to obtain the lens angle.

[0016] The present invention also provides a method for fitting progressive lenses using a positioning device for auxiliary marking of the lens frame, comprising the following steps: The eyeglass frame with the lens to be installed is mounted on the crossbar; the wearer wears the eyeglass frame holder; wherein, a support piece is installed at the lens position of the eyeglass frame; The wearer looks straight ahead into the distance and uses a verticality marking device to confirm that the pupil positioning hole in the far-light zone of the positioning device worn by the wearer is parallel to the ground; Adjust one of the sliding test blocks to move the far-light zone test slider horizontally and / or vertically until the wearer's pupil is aligned with the far-light zone pupil positioning hole. Mark the support plate through the far-light zone pupil positioning hole, and record the marked point as the first far-light zone fitting point. Adjust the other sliding test block and repeat the above operation, and record the marked point as the second far-light zone fitting point. Obtain the monocular pupillary height and monocular pupillary distance through the first and second far-light zone fitting points. Use a reflective mirror as an auxiliary observation tool and place it flat on a table. The reflective mirror is marked with circles. The wearer observes the circles on the reflective mirror in a reading posture. The observer is positioned opposite the wearer and observes the wearer's pupils through the reflection of the mirror. Adjust one of the sliding test blocks so that the near-light zone test slider moves horizontally and / or vertically until the wearer's pupil is aligned with the near-light zone pupil positioning ring, and keep the position of the sliding test block still; adjust the other sliding test block and repeat the above operation, keeping the position of the sliding test block still; The wearer removes the positioning device and the frame used for auxiliary marking of the frame support; The pupil positioning rings of the two near-light zone test sliders are marked on the support plate and are respectively denoted as the first near-light zone marking ring and the second near-light zone marking ring. The position of the near-light zone and the inward displacement of the near-light zone relative to the far-light zone are obtained through the center point of the first near-light zone marking ring and the center point of the second near-light zone marking ring. Mark the support plate with horizontal marking slots on the two near-light zone test sliders, and record them as the first progressive channel endpoint and the second progressive channel endpoint, respectively; measure the distance from the first far-light zone fitting point to the first progressive channel endpoint, and record it as the first progressive channel length; measure the distance from the second far-light zone fitting point to the second progressive channel endpoint, and record it as the second progressive channel length.

Figures 1-3The positioning device for auxiliary marking of the frame support includes a frame fixing frame 1, two sliding test blocks 2 and a verticality marking device 3; The eyeglass frame fixing bracket 1 includes a horizontal bar 11 and two vertical bar assemblies 12, with the two vertical bar assemblies 12 respectively disposed at both ends of the horizontal bar 11; Two sliding test blocks 2 are movably disposed on the vertical rod assembly 12. The two sliding test blocks 2 can move vertically along the extension direction of the vertical rod assembly 12 and can also move horizontally. The sliding test block 2 includes a high beam test slider 21 and a low beam test slider 22 that are arranged sequentially from top to bottom and connected to each other in a vertical direction; The high beam zone test slider 21 is provided with a cross mark 211, and a high beam zone pupil positioning hole 212 is provided through the intersection of the cross mark 211; The near beam test slider 22 has a near beam pupil positioning ring 221 and a horizontal marking groove 222 that communicates with the positioning through hole. The horizontal marking groove 222 is located above the positioning through hole and is tangent to the positioning through hole. The verticality marking device 3 is located in the middle of the horizontal frame.

[0029] This invention provides a positioning device for auxiliary marking of eyeglass frame lenses. Two sliding test blocks 2 are movably disposed on a vertical rod assembly 12. The two sliding test blocks 2 can move vertically along the extension direction of the vertical rod assembly 12 and horizontally. The high-light zone test slider 21 is provided with a cross mark 211, and a high-light zone pupil positioning hole 212 is provided through the intersection of the cross mark 211. The near-light zone test slider 22 is provided with a near-light zone pupil positioning ring 221 and a horizontal marking groove 222 communicating with the positioning through hole. The horizontal marking groove 222 is disposed above the positioning through hole and is tangent to the positioning through hole. When the wearer installs the eyeglass frame to be fitted with lenses into the positioning device for auxiliary marking of eyeglass frame lenses, and when obtaining the parameters of the high-light zone, the wearer looks straight ahead. The verticality marking device 3 ensures that the wearer's line of sight is level. At this time, by moving the sliding test block 2, the wearer's pupil is aligned with the pupil positioning hole 212 in the far-light zone. By marking the frame support with the pupil positioning hole 212 in the far-light zone, the position of the fitting point in the far-light zone, the pupillary height of one eye, and the pupillary distance of one eye can be obtained. When obtaining the parameters of the near-light zone, the wearer is in a reading posture with their head down. At this time, by moving the sliding test block 2 and observing with the reflector, the wearer's pupil is aligned with the pupil positioning ring 221 in the near-light zone. The positioning device used for auxiliary marking on the frame support is removed. By marking the frame support with the pupil positioning hole 212 in the far-light zone and the horizontal marking groove 222, the position of the near-light zone, the inward displacement of the near-light zone relative to the far-light zone, and the length of the progressive channel can be obtained. This invention uses a positioning device for auxiliary marking of the lens frame to obtain various data on the distance and near vision zones of progressive lenses. This facilitates personalized customization for different frames and different wearers' usage habits, improving the accuracy of progressive lens fitting and wearing comfort.

[0030] In this embodiment, "inner side" refers to the side of the locator closest to the eye after the locator for auxiliary marking of the eyeglass frame is worn.

[0031] In this embodiment, the high-beam zone test slider 21 is a transparent test slider, with cross marks 211 on both sides. The high-beam zone pupil positioning hole 212 passes through the transparent test slider. Because the high-beam zone test slider 21 is transparent and has cross marks 211 on both sides, when acquiring high-beam zone parameters, the wearer looks straight ahead, and the observer is positioned opposite the wearer. When the cross marks 211 on both sides of the transparent test slider are aligned, combined with the perpendicularity marking device 3, it indicates that the wearer's line of sight is straight ahead, which helps improve the accuracy of acquiring high-beam zone parameters.

[0032] In one embodiment, a cross mark 211 is provided on both sides of the transparent test slider, and the cross mark 211 is a cross-shaped print. In another embodiment, a cross mark 211 is provided on both sides of the transparent test slider, and the cross mark 211 is a cross-shaped groove.

[0033] Please see Figures 1-2 In this embodiment, the vertical rod assembly 12 includes a vertical track 121, which is vertically arranged on the horizontal rod 11; two sliding test blocks 2 are respectively movably arranged on the vertical track 121 in the vertical direction and can move in the horizontal direction on the vertical track 121.

[0034] Figure 4 This is a structural diagram of the verticality marking device. Please refer to [link / reference]. Figures 1-2 and Figure 4 In this embodiment, the verticality marking device 3 includes a verticality display 31 and a verticality pointer 32. The verticality display 31 is vertically disposed in the middle of the horizontal bar 11. An angle scale is provided at the lower part of the verticality display 31, wherein the angle scale has vertical markings, and the reading of the angle scale gradually increases outwards along the horizontal bar. One end of the verticality pointer 32 is rotatably disposed on the verticality display 31, and the other end extends towards the direction of the angle scale. When acquiring parameters of the far-light zone, the wearer looks straight ahead, and the verticality pointer 32 points vertically downwards, indicating that the pupil positioning hole 212 of the far-light zone is parallel to the ground at this time.

[0035] In one embodiment, the verticality display 31 is provided with an angle scale, which gradually increases from 0° along the horizontal bar 11 outwards, and the 0° scale line is set vertically, serving as a vertical marker. When acquiring parameters of the far-light zone, the wearer looks straight ahead, and the verticality pointer 32 points vertically downwards, coinciding with the 0° scale line, indicating that the wearer's line of sight is at eye level.

[0036] Please see Figures 1-2In this embodiment, the vertical rod assembly 12 further includes a vertical fixing rod 122, which is vertically fixed to the horizontal rod 11. The vertical track 121 is rotatably disposed on the horizontal rod 11 and can rotate relative to the vertical fixing rod 122 to form a certain angle, or rotate until it is in contact with the vertical fixing rod 122 until the verticality pointer 32 coincides with the vertical mark, indicating that the pupil positioning hole 212 in the far-light zone is parallel to the ground. Keeping the wearer in a level gaze position, the vertical track 121 is rotated in the direction toward the inside of the horizontal rod 11 until the vertical track 121 is in contact with the vertical fixing rod 122. Since the verticality pointer 32 remains vertically downward during the rotation, and the angle scale of the verticality display 31 rotates synchronously, the angle formed between the vertical track 121 and the vertical fixing rod 122 can be measured by observing the reading of the verticality pointer 32. This angle is recorded as the forward tilt angle of the frame.

[0039] In one embodiment, the sliding test block 2 and the vertical fixed rod 122 are located on the same plane. The horizontal moving device 4 drives the sliding test block 2 to move in the horizontal direction and can move to abut against the edge of the vertical rod assembly 12, so as to increase the range of motion of the sliding test block 2 in the horizontal direction and avoid interference from the vertical moving block 123, which would prevent the test from being performed according to the wearer's specific face shape.

[0040] In one embodiment, the horizontal moving device 4 protrudes from the side of the vertical track 121 facing outwards.

[0041] Figure 5This is a structural diagram of the positioning device used for auxiliary marking of the frame support at another angle. Please refer to [link / reference].

The sliding test block 2 is disposed on the inner side of the horizontal bar 11 relative to the vertical moving block 123 and is located on the same plane as the vertical fixed rod 122.

[0042] Please see Figure 5 In this embodiment, the positioning device for auxiliary marking of the frame support further includes a support clamping member 5. One end of the support clamping member 5 is rotatably disposed on the horizontal bar 11 and located inside the vertical bar assembly 12. A support clamping space is formed between the support clamping member 5 and the vertical bar assembly 12, and the support clamping member 5 can be opened or closed relative to the vertical bar assembly 12.

[0045] Please see Figure 3In this embodiment, the vertical center line of the near-vision pupil positioning ring 221 is offset towards the center of the frame holder 1 relative to the vertical center line of the far-vision pupil positioning hole 212. When using progressive lenses, the wearer's pupil position differs between the far-vision and near-vision zones. When looking at near objects, the pupil shifts inward. To adapt to different usage scenarios, the near-vision pupil positioning ring 221 is offset towards the center of the frame holder 1 relative to the vertical center line of the far-vision pupil positioning hole 212. During the switching between far-vision and near-vision testing, it can be quickly positioned by moving vertically, followed by fine adjustments. This minimizes the need for adjustments to the sliding test block 2 during testing, reducing operation time.

[0046] In one embodiment, the near-light pupil positioning ring 221 is offset by 2.5mm ± 0.5mm from the vertical center line of the far-light pupil positioning hole 212 towards the center of the frame holder 1.

The lens-to-eye distance measuring device 6 includes a lens-to-eye distance measuring ruler 61 and a horizontal fixing frame 62, the lens-to-eye distance measuring ruler 61 is movably disposed on the horizontal fixing frame 62, and extends from one end of the crossbar 11 in a direction close to the inside of the crossbar 11. When testing the lens-to-eye distance of the wearer, the lens-to-eye distance measuring ruler 61 is adjusted so that its front end is tangent to the front end of the wearer's cornea. At this time, the distance between the front end of the lens-to-eye distance measuring ruler 61 and the inside of the lens can be obtained, thus obtaining the lens-to-eye distance.

[0048] In one embodiment, the horizontal mounting bracket 62 is movably mounted on the crossbar 11 in the horizontal direction to adjust the measurement position of the eye distance according to the user's specific situation.

[0050] Example 2 This embodiment provides a method for fitting progressive lenses using a positioning device for auxiliary marking of the lens frame as described in Embodiment 1. Figure 7 This is a flowchart of the progressive lens fitting process using a positioning device for auxiliary marking of the frame support lens in Example 2. Please refer to [link / reference]. Figure 7 The method for fitting progressive lenses using a positioning device for auxiliary marking of the frame support includes the following steps: Step S1: Install the eyeglass frame with the lens to be installed onto the crossbar 11; allow the wearer to wear the eyeglass frame holder 1; wherein, a support piece is installed at the lens position of the eyeglass frame; Step S2: The wearer looks straight ahead into the distance and confirms that the pupil positioning hole 212 is parallel to the ground using the verticality marking device 3; Adjust one of the sliding test blocks 2 so that the far-light zone test slider 21 moves horizontally and / or vertically until the wearer's pupil is aligned with the far-light zone pupil positioning hole 212. Mark the support plate through the far-light zone pupil positioning hole 212, and record the marked point as the first far-light zone fitting point. Adjust the other sliding test block 2 and repeat the above operation, and record the marked point as the second far-light zone fitting point. Through the first far-light zone fitting point and the second far-light zone fitting point, obtain the position of the far-light zone fitting point, the monocular pupillary height, and the monocular pupillary distance.

[0051] In this embodiment, the first and second high-beam fitting points are obtained by marking points using the "high-beam pupil positioning hole 212".

[0052] Step S3: Take a reflector as an auxiliary observation tool and place it flat on the table; there are circles marked on the reflector; the wearer observes the circles on the reflector in a reading posture; the observer is opposite the wearer and observes the wearer's pupils through the reflection of the reflector. Adjust one of the sliding test blocks 2 so that the near vision test slider 22 moves horizontally and / or vertically until the wearer's pupil is aligned with the near vision pupil positioning ring 221, and keep the position of the sliding test block 2 unchanged; adjust the other sliding test block 2 and repeat the above operation, keeping the position of the sliding test block 2 unchanged.

[0053] Step S4: The wearer removes the positioning device and the frame used for auxiliary marking of the frame support; The pupil positioning rings 221 of the two near-light zone test sliders 22 are marked on the support plate and are respectively denoted as the first near-light zone marking ring and the second near-light zone marking ring; the center position of the near-light zone and the inward displacement of the near-light zone relative to the far-light zone are obtained through the center point of the first near-light zone marking ring and the center point of the second near-light zone marking ring. Markings are made on the support plate using the horizontal marking slots 222 of the two near-light zone test sliders 22, which are respectively recorded as the first progressive channel endpoint and the second progressive channel endpoint; the distance from the first far-light zone fitting point to the first progressive channel endpoint is measured and recorded as the first progressive channel length; the distance from the second far-light zone fitting point to the second progressive channel endpoint is measured and recorded as the second progressive channel length.

[0054] In this embodiment, a first near-light zone marking circle and a second near-light zone marking circle are obtained by drawing a circle with the near-light zone pupil positioning circle 221. Then, the center point is found within the first near-light zone marking circle and the second near-light zone marking circle to obtain the position of the near-light zone and the inward displacement of the near-light zone relative to the far-light zone.

[0055] In step S2, when acquiring parameters for the far-light zone, the wearer looks straight ahead, and the observer is positioned opposite the wearer. When the crosshairs 211 on both sides of the transparent test slider are aligned, combined with the verticality marking device 3, it indicates that the pupil positioning hole for the far-light zone is parallel to the ground at this time. Specifically, the verticality pointer 32 points vertically downwards. When the verticality pointer 32 coincides with the vertical mark, it indicates that the wearer's line of sight is at eye level.

[0056] In step S2, when obtaining the parameters of the far-light zone, the wearer looks straight ahead. At this time, the vertical track 121 is rotated towards the outside of the horizontal bar 11 so that the vertical track 121 and the vertical fixing rod 122 form a certain angle until the verticality pointer 32 coincides with the vertical mark, indicating that the pupil positioning hole 212 of the far-light zone is parallel to the ground. After obtaining the first and second far-light zone fitting points, the wearer is kept looking straight ahead, and the vertical track 121 is rotated towards the inside of the horizontal bar 11 until the vertical track 121 is in contact with the vertical fixing rod 122. Since the verticality pointer 32 remains vertically downward during the rotation and the angle scale of the verticality display table 31 rotates synchronously, the angle formed between the vertical track 121 and the vertical fixing rod 122 can be measured by observing the reading of the verticality pointer 32. This angle is recorded as the forward tilt angle of the frame.

[0057] The method for fitting progressive lenses using the positioning device for auxiliary marking of the frame support lens in Example 1 further includes the following steps: Step S5: When testing the wearer's lens-to-eye distance, adjust the lens-to-eye distance measuring ruler 61 so that its front end is tangent to the front end of the wearer's cornea. At this time, the distance between the front end of the lens-to-eye distance measuring ruler 61 and the inner side of the lens can be obtained, thus obtaining the lens-to-eye distance. When the frame is fixed on the horizontal bar 11, the observer looks down and looks at the scale value of the lens angle measuring ruler to obtain the lens angle.

[0058] The positioning device for auxiliary marking of lens frames provided in this embodiment determines accurate parameters such as the actual distance vision zone position, near vision zone position, and channel length based on different frames selected by different wearers. This facilitates personalized customization of progressive lenses based on the correct refractive power, frame shape, and available light zone position, and allows for the selection of suitable frames. By judging the size of the frame's tilt angle, lens-to-eye distance, and lens angle, it determines whether the selected frame is suitable for fitting progressive lenses. The positioning device for auxiliary marking of lens frames obtains multiple parameters required for lens fitting, improving lens fitting efficiency.
