Description

Technical Field

[0001] The invention relates to the technical field of optometry and glasses fitting, in particular to a glasses fitting and measuring frame. Background Art

[0002] Glasses are a common product for vision correction. In order to accurately fit glasses, optometry is often required. In order to obtain accurate optometry results, the optometry process involves complex optometry problems and a variety of human eye visual parameters.

[0003] From the perspective of optometry, the geometric center of the pupil of the human eye is not necessarily the optical center of the eye. The reason is that the diameter of the fovea on the retina of the fundus is about 1 millimeter (mm), which is also the focal center of the eye's optical system. The physiological characteristic of the human eye is that the fovea is not the axial end point of the eye, but it is the axial end point of the eye's optical system, and its physiological position is biased towards the temporal side.

[0004] That is, generally speaking, there is an angle between the eye axis and the visual axis, which is called the kappa angle in medical terms. In anatomy, the degree of the kappa angle varies from person to person, and this difference is an important parameter for configuring high-end lenses.

[0005] In addition to the kappa angle, accurate optometry may involve various other parameters. However, existing pupil distance measuring instruments or other measurement methods cannot accurately and conveniently measure various parameters of the human eye. Summary of the invention

[0042] As mentioned in the background art, existing pupil distance measuring instruments or other measurement methods cannot accurately measure the kappa angle of the human eye.

[0043] To solve the above technical problems, an embodiment of the present invention provides a glasses fitting and measuring frame, comprising: a main beam, the main beam having a first end and a second end opposite to each other; a nose pad assembly, connected to the main beam and located between the first end and the second end of the main beam; a first temple, connected to the first end of the main beam; a second temple, connected to the second end of the main beam; a first lens fixing frame, connected to the main beam and movable in a transverse direction and a longitudinal direction, the first lens fixing frame being located between the nose pad assembly and the first temple, the transverse direction and the longitudinal direction being perpendicular to each other, and the transverse direction being parallel to an extension direction of the main beam from the first end to the second end; a second lens fixing frame, connected to the main beam and movable in a transverse direction and a longitudinal direction, the second lens fixing frame being located between the nose pad assembly and the second temple.

[0044] This embodiment provides an improved eyeglass fitting and measuring frame, which can accurately and conveniently measure various parameters of the human eye. Specifically, the first lens fixing frame and the second lens fixing frame can independently move left and right along the lateral direction on the main beam, and during the eye test process, the positions of the left and right lenses can be flexibly adjusted, making it possible to measure different parameters of the human eye.

[0045] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0046] Figure 1 It is a schematic diagram of a glasses fitting and measuring frame according to an embodiment of the present invention.

[0047] The eyeglass fitting measurement frame of this embodiment can be applied to optometry scenarios, such as optometry scenarios for configuring high-end optical lenses such as progressive multifocal lenses, wherein the high-end optical lenses refer to the dimensional configuration of the lens diopter using one or two free-form surfaces.

[0048] Specifically, refer to Figure 1 The glasses fitting and measuring frame 1 described in this embodiment may include: a main beam 10, and the main beam 10 has a first end 10a and a second end 10b opposite to each other.

[0049] For ease of expression, the extension direction of the main beam 10 from the first end 10a to the second end 10b is recorded as the transverse direction (indicated by ±x in the figure), and the directions perpendicular to the transverse direction (indicated by ±x direction in the figure) are recorded as the longitudinal direction (indicated by ±z in the figure) and the depth direction (indicated by ±y).

[0050] When the lateral direction (±x direction in the figure) is the horizontal direction, the longitudinal direction (±z direction in the figure) is the gravity direction, and the depth direction (±y direction in the figure) is perpendicular to the plane formed by the horizontal direction and the gravity direction.

[0051] More specifically, the eyeglass fitting and measuring frame 1 may further include: a nose pad assembly 11 connected to the main beam 10 and located between the first end 10 a and the second end 10 b of the main beam 10 .

[0052] For example, the nose pad assembly 11 can be fixed to the midpoint of the main beam 10 along the transverse direction (±x direction shown in the figure), that is, the distance from the nose pad assembly 11 to the first end 10a of the main beam 10 is equal to the distance from the nose pad assembly 11 to the second end 10b of the main beam 10.

[0053] The extending direction of the nose pad component 11 may be substantially parallel to the longitudinal direction (±z direction in the figure).

[0054] One end of the nose pad component 11 along the extension direction can be fixed to the main beam 10. During eye examination, the free end of the nose pad component 11 can contact the bridge of the nose to support the glasses fitting and measuring frame 1 on the bridge of the nose of the person being tested.

[0055] Furthermore, the eyeglass fitting and measuring frame 1 may further include: a first temple 12 connected to the first end 10 a of the main beam 10 ; and a second temple 13 connected to the second end 10 b of the main beam 10 .

[0056] For example, any one of the first temple 12 and the second temple 13 can be hinged to the main beam 10, and can rotate around the hinge point with the main beam 10 in a plane formed by the transverse direction (±x direction in the figure) and the depth direction (±y direction in the figure) to switch between the closed position and the open position. Figure 1 The open position is switched before.

[0057] During eye examination, the first temple 12 and the second temple 13 are respectively rotated around their respective hinge points to Figure 1 The first temple 12 and the second temple 13 are in the open position shown in the figure. At this time, the extension direction of the first temple 12 and the second temple 13 are parallel to each other, and the extension direction is parallel to the depth direction (±y direction in the figure). If necessary, the angle between the extension direction of the temple and the longitudinal direction (±z direction in the figure) can be adjusted to improve the comfort of the glasses fitting measurement frame 1 when worn on the face of the testee. At this time, the extension direction of the temple is no longer parallel to the depth direction (±y direction in the figure).

[0058] Further, maintaining Figure 1 The eyeglass fitting and measuring frame 1 in the state shown is worn on the face of the person being tested, the ear hooks of the two temples are coupled to the corresponding ears, and the free end of the nose pad assembly 11 is supported on the bridge of the nose of the person being tested.

[0059] The first temple 12 and the second temple 13 are respectively connected to two ends of the main beam 10 through a fixing portion, and the extending direction of the fixing portion is the longitudinal direction (±z direction in the figure).

[0060] For example, the fixing portion may include a second lateral adjustment member 17 and a third lateral adjustment member 18 .

[0061] Furthermore, the glasses fitting and measuring frame 1 may also include: a first lens fixing frame 14, which is connected to the main beam 10 and can move along the lateral direction (±x direction in the figure) and the longitudinal direction (±z direction in the figure), and the first lens fixing frame 14 can be located between the nose pad assembly 11 and the first temple 12; a second lens fixing frame 15, which is connected to the main beam 10 and can move along the lateral direction (±x direction in the figure) and the longitudinal direction (±z direction in the figure), and the second lens fixing frame 15 can be located between the nose pad assembly 11 and the second temple 13.

[0062] For example, the first lens holder 14 and the second lens holder 15 can both be used to carry lenses (also called test pieces). During eye testing, by moving the first lens holder 14 and / or the second lens holder 15 in the ±x direction and the ±z direction, the spacing along the lateral direction (±x direction in the figure) and the height difference along the longitudinal direction (±z direction in the figure) of the lenses respectively carried on the two lens holders can be adjusted, so that the positions of the lenses on both sides are adapted to the positions of the eyes of the testee.

[0063] In one specific implementation, reference Figure 1 and Figure 2 Any one of the first lens fixing frame 14 and the second lens fixing frame 15 may include: a supporting portion 140, the supporting portion 140 may include a longitudinal adjustment portion 141 and a first transverse adjustment portion 142, the first transverse adjustment portion 142 is connected to the main beam 10 and can move relative to the main beam 10 along a transverse direction (±x direction in the figure), the longitudinal adjustment portion 141 is connected to the first transverse adjustment portion 142 and moves with the first transverse adjustment portion 142; a lens bearing portion 143, the lens bearing portion 143 can be connected to the longitudinal adjustment portion 141, and driven by the longitudinal adjustment portion 141 to move along the longitudinal direction (±z direction in the figure).

[0064] In one specific implementation, along Figure 2 From the perspective shown, the support member 140 may be in an inverted L-shape, and the support member 140 of the first lens fixing frame 14 and the support member 140 of the second lens fixing frame 15 may be symmetrically arranged, and the axis of symmetry may be the nose pad assembly 11 .

[0065] Specifically, for the support member 140 of the first lens fixing frame 14, the first transverse adjustment member 142 can be arranged below the main beam 10 along the -z direction and between the main beam 10 and the lens bearing portion 143, and the upper end of the longitudinal adjustment member 141 along the +z direction can be connected to one end of the first transverse adjustment member 142 along the transverse direction (±x direction) close to the first temple 12.

[0066] Similarly, for the support member 140 of the second lens fixing frame 15, the first transverse adjustment member 142 can be arranged below the main beam 10 along the -z direction and between the main beam 10 and the lens bearing portion 143, and the upper end of the longitudinal adjustment member 141 along the +z direction can be connected to one end of the first transverse adjustment member 142 along the transverse direction (±x direction) close to the second temple 13.

[0067] In one specific implementation, reference Figure 3 The longitudinal adjustment portion 141 may include: a longitudinal bracket 144; a first screw 145, wherein the first screw 145 is arranged on the longitudinal bracket 144 along the longitudinal direction (±z direction as shown in the figure); a first spiral transmission portion 146, wherein the first spiral transmission portion 146 is screwed to the first screw 145, and as the first screw 145 rotates, the first spiral transmission portion 146 moves along the first screw 145, and the lens carrying portion 143 is connected to the first spiral transmission portion 146.

[0068] For example, the outer surface of the first screw 145 may have a trapezoidal thread (not shown), and the first spiral transmission part 146 has a matching internal thread, so that the first spiral transmission part 146 and the first screw 145 can realize spiral transmission. By turning the connected first knob 147, the first screw 145 rotates around its own axis, and the first spiral transmission part 146 moves up and down along the longitudinal direction (±z direction in the figure) as the first screw 145 rotates, thereby driving the lens carrying part 143 connected thereto to move up and down along the longitudinal direction (±z direction in the figure).

[0069] In a specific implementation, the front side of the longitudinal support 144 along the -y direction may have scale lines, such as Figure 2 As shown, the position of the lens carrying portion 143 in the longitudinal direction (±z direction in the figure) can be read during optometry. Accordingly, the front side of the lens carrying portion 143 along the -y direction can be provided with an indicating arrow to indicate the current longitudinal position of the lens carrying portion 143. The front side along the -y direction can be the side facing the optometrist during optometry.

[0070] In a specific implementation, continue to refer to Figure 3The longitudinal bracket 144 may include: a longitudinal bracket body 148 for supporting the first screw rod 145; a first limiting portion 149, which is arranged at one end or both ends of the longitudinal bracket body 148 and is used to limit the movement stroke of the first spiral transmission portion 146 on the first screw rod 145.

[0071] In a specific implementation, the first fixing parts 150 may be respectively provided at both ends of the longitudinal support body 148 along the longitudinal direction (±z direction in the figure) to fix the first screw 145 to the longitudinal support body 148. The first fixing part 150 may be provided with through holes (not shown) along the longitudinal direction (±z direction in the figure), and the first screw 145 sequentially passes through the through holes of each first fixing part 150 to fix the first screw 145 between the longitudinal support body 148 and the first fixing part 150 while ensuring that the first screw 145 can rotate around its own axis.

[0072] Specifically, in Figure 3 Of the two first fixing parts 150 shown, the first fixing part 150 disposed at the top along the +z direction can be used to prevent the first screw rod 145 from falling from the longitudinal bracket body 148. For example, an anti-falling part 151 can be formed at one end of the first screw rod 145 that is not connected to the first knob 147, and the diameter of the anti-falling part 151 can be larger than the diameter of the through hole of the first fixing part 150 to ensure that the first screw rod 145 does not fall from the through hole.

[0073] Further, in Figure 3 Of the two first fixing portions 150 shown, the first fixing portion 150 disposed at the lower side along the +z direction may be used to limit the upward movement of the first screw 145 along the +z direction.

[0074] Further, Figure 3 At least one of the two first fixing parts 150 shown may also integrate the function of the first limiting part 149 to limit the highest point and the lowest point of the first spiral transmission part 146 moving along the longitudinal direction (±z direction in the figure). For example, the first fixing part 150 disposed at the top along the +z direction may be used to limit the highest point of the first spiral transmission part 146 moving along the +z direction.

[0075] Furthermore, the first limiting portion 149 can also be disposed in the middle of the longitudinal support body 148, such as Figure 3 The first limiting portion 149 is located between the upper and lower first fixing portions 150. Similar to the first fixing portion 150, the first limiting portion 149 may also be provided with a through hole (not shown) along the longitudinal direction (±z direction in the figure) for the first screw rod 145 to pass through, and when the first spiral transmission portion 146 moves to abut against the first limiting portion 149, it is restricted from continuing to move.

[0076] exist Figure 3 In the illustrated arrangement, the first limiting portion 149 located in the middle of the longitudinal support body 148 can be used to limit the lowest point of the first spiral transmission portion 146 moving along the -z direction.

[0077] In practical applications, the setting position of each first limiting portion 149 can be reasonably adjusted according to the allowed movement stroke of the first spiral transmission portion 146.

[0078] The arrangement of the longitudinal adjustment member 141 on the second lens fixing frame 15 can be referred to Figure 3 The detailed description of the above-mentioned arrangement of the longitudinal adjustment member 141 on the first lens fixing frame 14 is not repeated here.

[0079] In one specific implementation, reference Figures 1 to 3 The lens carrying portion 143 may include: a hollow frame portion 152; and a plurality of buckle portions 153 disposed on the frame portion 152, wherein the plurality of buckle portions 153 are used to fix the lens (not shown).

[0080] For example, a plurality of limiting grooves 154 may be provided in parallel along the depth direction (±y direction in the figure) on one side of the buckle portion 153 facing the center of the frame portion 152 to fix a plurality of lenses at the same time.

[0081] For another example, the number of the buckle portions 153 disposed on each lens carrying portion 143 may be two. Figure 1 shown.

[0082] In a specific implementation, continue to refer to Figures 1 to 3 The lens carrying portion 143 may further include: an elastic guide portion 155, which is arranged on the frame portion 152 and is located on the same side of the frame portion 152 as the multiple snap portions 153, one end of the elastic guide portion 155 is fixed to the frame portion 152, and the other end of the elastic guide portion 155 is a free end, and at least a portion of the elastic guide portion 155 is arc-shaped.

[0083] For example, one end of the elastic guide portion 155 fixed to the frame portion 152 may extend to the buckle portion 153 so as to accurately guide the lens to the buckle portion 153 when the lens is installed.

[0084] For another example, a section of the free end of the elastic guide portion 155 may be parallel to the lateral direction (±x direction in the figure), and the free end may be close to the longitudinal bracket body 148 to serve as a scale indicator to indicate the position of the lens supporting portion 143 in the longitudinal direction (±z direction in the figure).

[0085] In a specific implementation, the curvature of the arc-shaped portion of the elastic guide portion 155 may be matched with the contour of the frame portion 152 to achieve a better guiding effect.

[0086] In a specific implementation, the elastic guide portion 155 and the buckle portion 153 may both be disposed on the front side of the frame portion 152 along the −y direction.

[0087] In one variation, reference Figure 3 When worn on the face of a person being tested for an eye test, a plurality of buckle portions 153 may be provided on the side of the lens bearing portion 143 close to the face of the person, and a plurality of limit grooves (not shown) may be provided in parallel along the depth direction (±y direction shown in the figure) on the side of each buckle portion 153 facing the center of the frame portion 152, so that the lens bearing portion 143 can carry more lenses at the same time.

[0088] In one specific implementation, reference Figure 4 The main beam 10 may include: a main beam body 100, the main beam body 100 is arranged in a transverse direction (±x direction in the figure) and has a first end 100a and a second end 100b opposite to each other. The first end 100a of the main beam body 100 may correspond to the first end 10a of the main beam 10, and the second end 100b of the main beam body 100 may correspond to the second end 10b of the main beam 10.

[0089] For example, the main beam body 100 may be a sleeve, and a through hole connecting the first end 100a and the second end 100b is opened along the transverse direction (±x direction in the figure).

[0090] Alternatively, in order to improve the rigidity, the middle section of the main beam body 100 connected to the nose pad assembly 11 may be solid, and a through hole extending toward the opposite end may be respectively formed at the first end 100a and the second end 100b.

[0091] Furthermore, the main beam 10 may also include: a second screw 101, which is arranged on one side of the main beam body 100 close to the first end 100a along the lateral direction (±x direction in the figure); a second spiral transmission part 102, which is screwed to the second screw 101, and as the second screw 101 rotates, the second spiral transmission part 102 moves along the second screw 101, and the first lens fixing frame 14 is connected to the second spiral transmission part 102.

[0092] For example, the second screw rod 101 and the second screw transmission part 102 screwed thereon can extend from the first end 100a into the hollow main beam body 100, and the second knob 103 connected to the second screw rod 101 can extend from the first end 100a. The outer surface of the second screw rod 101 can have a trapezoidal thread (not shown), and the second screw transmission part 102 has a matching internal thread, so that the second screw transmission part 102 and the second screw rod 101 can realize screw transmission.

[0093] Specifically, the first lens fixing frame 14 can be connected to the second spiral transmission part 102 via a first transverse adjusting member 142. For example, at least the first transverse adjusting member 142 and the second spiral transmission part 102 can be integrally formed. Alternatively, the first transverse adjusting member 142 can be connected to the second spiral transmission part 102 by bonding.

[0094] By rotating the second knob 103, the second screw 101 rotates around its own axis, and the second spiral transmission part 102 moves left and right along the lateral direction (±x direction shown in the figure) as the second screw 101 rotates, thereby driving the first lateral adjustment member 142 connected thereto to move left and right along the lateral direction (±x direction shown in the figure).

[0095] Furthermore, the main beam 10 may also include: a third screw 104, which is arranged on one side of the main beam body 100 close to the second end 100b along the lateral direction (±x direction in the figure); a third spiral transmission part 105, which is screwed to the third screw 104. As the third screw 104 rotates, the third spiral transmission part 105 moves along the third screw 104, and the second lens fixing frame 15 is connected to the third spiral transmission part 105.

[0096] For example, the third screw rod 104 and the third screw transmission part 105 screwed thereon can extend from the second end 100b into the hollow main beam body 100, and the third knob 106 connected to the third screw rod 104 can extend from the second end 100b. The outer surface of the third screw rod 104 can have a trapezoidal thread (not shown), and the third screw transmission part 105 has a matching internal thread, so that the third screw transmission part 105 and the third screw rod 104 can realize screw transmission.

[0097] Specifically, the second lens fixing frame 15 can be connected to the third screw transmission part 105 through the first transverse adjustment member 142. For example, at least the first transverse adjustment member 142 and the third screw transmission part 105 can be integrally formed. Alternatively, the first transverse adjustment member 142 can be bonded to the third screw transmission part 105.

[0098] By rotating the third knob 106, the third screw 104 rotates around its own axis, and the third spiral transmission part 105 moves left and right along the lateral direction (±x direction shown in the figure) as the third screw 104 rotates, thereby driving the first lateral adjustment member 142 connected thereto to move left and right along the lateral direction (±x direction shown in the figure).

[0099] In one specific implementation, reference Figure 1 , Figure 2 and Figure 4 The main beam body 100 may have scale lines to read the position of the first transverse adjustment member 142 in the transverse direction (±x direction in the figure). This position can be used to indicate the position of the lenses fixed on the first lens fixing frame 14 and the second lens fixing frame 15 in the transverse direction (±x direction in the figure).

[0100] Furthermore, an indicator block 174 may be provided on the first transverse adjustment member 142 for indicating a scale position of the first transverse adjustment member 142 on the main beam body 100 .

[0101] In a specific implementation, continue to refer to Figure 4 The main beam 10 may further include: a second limiting portion 107, which is arranged on the main beam body 100, and the second limiting portion 107 is located between the first end 100a of the main beam body 100 and the nose pad assembly 11, and is used to limit the movement stroke of the second spiral transmission portion 102 on the second screw 101.

[0102] For example, the second limiting portion 107 can be arranged in the hollow main beam body 100, and a through hole for the second screw 101 to pass through is opened along the transverse direction (±x direction in the figure), and when the second spiral transmission portion 102 moves to abut against the second limiting portion 107, it is restricted from continuing to move.

[0103] In a specific implementation, the main beam body 100 may be provided with a second fixing portion 163 to fix the second screw rod 101 in the main beam body 100. For example, the second fixing portion 163 is provided with a through hole (not shown) along the transverse direction (±x direction in the figure), and the end of the second screw rod 101 extending into the main beam body 100 is formed with an anti-dropping portion 109 after passing through the second fixing portion 163, and the diameter of the anti-dropping portion 109 may be greater than the diameter of the through hole of the second fixing portion 163, so as to ensure that the second screw rod 101 will not be pulled out of the main beam body 100.

[0104] Furthermore, the second fixing portion 163 may integrate the limiting function of the second limiting portion 107 to limit the maximum rightward movement stroke of the second screw transmission portion 102 along the +x direction.

[0105] Furthermore, the second limiting portion 107 disposed between the first end 100a of the main beam body 100 and the second fixing portion 163 can be used to limit the maximum leftward movement stroke of the second spiral transmission portion 102 along the -x direction.

[0106] Similarly, the main beam 10 may also include: a third limiting portion 108, which is arranged on the main beam body 100, and the third limiting portion 108 may be located between the second end 100b of the main beam body 100 and the nose pad assembly 11, for limiting the movement stroke of the third spiral transmission portion 105 on the third screw 104.

[0107] For example, the third limiting portion 108 can be arranged in the hollow main beam body 100, and a through hole (not shown) for the third screw 104 to pass through is opened along the transverse direction (±x direction shown in the figure). When the third spiral transmission portion 105 moves to abut against the third limiting portion 108, it is restricted from continuing to move.

[0108] In a specific implementation, the main beam body 100 may be provided with a third fixing portion 164 to fix the third screw 104 in the main beam body 100. For example, the third fixing portion 164 is provided with a through hole (not shown) along the transverse direction (±x direction in the figure), and the end of the third screw 104 extending into the main beam body 100 is formed with an anti-dropping portion 109 after passing through the third fixing portion 164. The diameter of the anti-dropping portion 109 may be greater than the diameter of the through hole of the third fixing portion 164 to ensure that the third screw 104 will not be pulled out of the main beam body 100.

[0109] Furthermore, the third fixing portion 164 may integrate the limiting function of the third limiting portion 108 to limit the maximum leftward movement stroke of the third spiral transmission portion 105 along the −x direction.

[0110] Furthermore, the third limiting portion 108 disposed between the second end 100 b of the main beam body 100 and the third fixing portion 164 can be used to limit the maximum rightward movement stroke of the third spiral transmission portion 105 along the +x direction.

[0111] In one specific implementation, reference Figure 4, a slot body (not shown) connected to the hollow area of ​​the main beam body 100 may be provided at the lower end of the main beam body 100 along the -z direction, and the extension direction of the slot body may be parallel to the transverse direction (±x direction shown in the figure). Furthermore, the second spiral transmission part 102 located in the main beam body 100 may extend from the slot body to the main beam body 100 to connect with the corresponding first transverse adjustment member 142 located below the main beam body 100 along the -z direction. Similarly, the third spiral transmission part 105 located in the main beam body 100 may extend from the slot body to the main beam body 100 to connect with the corresponding first transverse adjustment member 142 located below the main beam body 100 along the -z direction. Thus, the slot body may also play a limiting role to ensure that the spiral motion of the screw can be effectively converted into transverse motion.

[0112] In one specific implementation, reference Figure 5 and Figure 6 The nose pad assembly 11 may include: an extension arm 183, which is connected to the main beam 10 and is located between the first end 10a and the second end 10b of the main beam 10; an adjustment mechanism 184 and a nose pad 112, wherein the nose pad 112 is connected to the extension arm 183 via the adjustment mechanism 184, and the nose pad 112 has a contact surface (such as the first surface 118a of the nose pad main body 118 shown in the figure) that contacts a human nose (such as the nose of a test subject), and the adjustment mechanism 184 is used to adjust the shape of the contact surface of the nose pad 112.

[0113] In a specific implementation, the extension arm 183 may include: a fixing portion 110, connected between the first end 10a and the second end 10b of the main beam 10, and extending along the longitudinal direction (±z direction as shown in the figure); a connecting and adjusting portion 111, connected to the fixing portion 110 and movable relative to the fixing portion 110 along the longitudinal direction (±z direction as shown in the figure); and the adjusting mechanism 184 is connected to the end 111b of the connecting and adjusting portion 111 away from the fixing portion 110.

[0114] In a specific implementation, the fixing portion 110 can be hinged to the main beam 10 and can rotate in a first plane, which is perpendicular to the transverse direction (±x direction in the figure). Thus, the distance between the plane where the lens is located (which can be called the frame plane) and the eye of the testee in the depth direction (±y direction in the figure) can be adjusted.

[0115] For example, refer to Figure 1 , Figure 5 and Figure 6A bracket 113 may be provided on the front side of the main beam body 100 along the -y direction. The bracket 113 may include a front wall 113a parallel to a third plane, the third plane is parallel to a plane formed by the transverse direction (±x direction in the figure) and the longitudinal direction (±z direction in the figure), and a pair of side walls 113b parallel to the first plane.

[0116] Specifically, the pair of side walls 113 b are spaced apart along the lateral direction (±x direction shown in the figure), and one side of the pair of side walls 113 along the depth direction (±y direction shown in the figure) is connected to the front wall 113 a respectively, and the other side is connected to the main beam body 100 respectively.

[0117] In a specific implementation, the fixing portion 110 has a first end 110a and a second end 110b opposite to each other along the longitudinal direction (±z direction in the figure), and the first end 110a of the fixing portion 110 extends into a space enclosed by the front wall 113a and a pair of side walls 113b of the bracket 113, and is hinged to the pair of side walls 113b, and the hinge point is recorded as hinge point A. The front wall 113a of the bracket 113 is provided with a through hole for the pin 114 to pass through.

[0118] Furthermore, the pin 114 can move in the through hole toward or away from the fixing portion 110 , so that the fixing portion 110 can rotate in the first plane with the hinge point A as the axis.

[0119] In a specific implementation, a spring sheet 117 may also be provided on the side of the front wall 113a of the bracket 113 facing the fixed portion 110. One end 117a of the spring sheet 117 may be fixed to the side of the front wall 113a facing the fixed portion 110 by laser welding, and the other end 117b of the spring sheet 117 is abutted against the first end 110a of the fixed portion 110.

[0120] For example, the other end 117 b of the spring sheet 117 may abut against a protrusion 165 of the fixing portion 110 . The protrusion 165 may be disposed on a surface of the first end 110 a of the fixing portion 110 facing the front wall 113 a of the bracket 113 .

[0121] Therefore, through the cooperation of the pin 114 and the spring sheet 117, a restoring force of the fulcrum can be provided to ensure that the fixing portion 110 can be stabilized at a suitable position when it is moved to the appropriate position in the first plane by the action of the pin 114.

[0122] In a specific implementation, continue to refer to Figure 5 and Figure 6The fixing portion 110 may be a hollow structure, and an opening exposing its internal hollow structure is provided at the second end 110b, and one end 111a of the connecting adjusting portion 111 extends into the fixing portion 110 from the opening, and is threadedly connected to a fixing portion screw 115 extending from the first end 110a of the fixing portion 110 into the fixing portion 110.

[0123] Specifically, one end 111 a of the connection adjustment portion 111 may be provided with a coupling portion 175 to be threadedly connected to the fixing portion screw 115 and to be movable up and down along the fixing portion screw 115 .

[0124] For example, the coupling portion 175 may be a coupling hole opened inwardly from the first end 111a of the connection adjustment portion 111 along the longitudinal direction (±z direction in the figure), the coupling hole has an internal thread, and the surface of the fixing portion screw 115 has an external thread connection. Inside the fixing portion 110, the fixing portion screw 115 extends into the coupling hole to achieve thread connection.

[0125] Furthermore, one end of the fixing screw 115 extending from the first end 110a of the fixing part 110 can be connected to the sixth knob 176. Rotating the sixth knob 176 can drive the fixing screw 115 to rotate around its own axis to adjust the threaded length in the coupling hole.

[0126] Therefore, by rotating the sixth knob 176 , the length of the portion of the connecting adjustment portion 111 extending into the interior of the fixing portion 110 can be adjusted to achieve the effect of adjusting the distance between the nose pad 112 and the fixing portion 110 .

[0127] Furthermore, both the fixing portion 110 and the connection adjustment portion 111 may be square tubes.

[0128] Furthermore, a supporting component, such as a spring 116, may be provided in the fixing portion 110. The spring 116 is provided in the hollow structure of the fixing portion 110, and one end of the spring 116 along the extension direction abuts against the first end 110a of the fixing portion 110, and the other end is connected to one end 111a of the connection adjustment portion 111, so as to optimize the overall stability when adjusting the distance between the nose pad 112 and the fixing portion 110, and play a rebound and stabilizing role.

[0129] In a specific implementation, continue to refer to Figure 5 The nose pad 112 may include: a nose pad body 118 for contacting a human nose; and a deformation portion 119, wherein the deformation portion 119 is attached to the nose pad body 118 and has elasticity.

[0130] For example, the nose pad body 118 can be made of an elastic stainless steel sheet as a base sheet and covered with a silicone coat.

[0131] The nose pad body 118 has a first surface 118 a and a second surface 118 b opposite to each other, wherein the first surface 118 a may be adapted to form the contact surface and contact with a human nose.

[0132] In a specific implementation, an inserting portion 156 is provided at a position near the end of the nose pad body 118 on the second surface 118b of the nose pad body 118. For any inserting portion 156, an inserting opening 166 for the deforming portion 119 to extend into is provided on the side of the inserting portion 156 facing the other inserting portion 156; an opening 157 for the deforming portion 119 to extend out is provided on the side of the inserting portion 156 away from the other inserting portion 156; and an adapting hole 158 is provided on the surface of the inserting portion 156 to couple with the deforming portion 119.

[0133] Thus, the insertion portion 156 can ensure that the deformation portion 119 is attached to the nose pad body 118 , and the shape of the contact surface can be changed by the elasticity of the deformation portion 119 .

[0134] In a specific implementation, the adjustment mechanism 184 may include: a through-screw 160 disposed at the end of the extension arm 183 .

[0135] For example, one end of the through screw 160 may be fixed to an end 111 b of the connection adjustment portion 111 away from the fixing portion 110 .

[0136] For another example, the angle between the extension direction of the through screw 160 and the extension direction of the extension arm 183 is greater than 90 degrees and less than 180 degrees, so that the position of the nose pad 112 is more consistent with the physiological characteristics of the human face.

[0137] Furthermore, the adjustment mechanism 184 may also include: an adjustment nut 161, which is screwed to the through screw 160 and can move up and down along the through screw 160, and the adjustment nut 161 pushes or releases the nose pad 112 to change the shape of the contact surface.

[0138] For example, the adjusting nut 161 may be a wide-mouthed nut member with an inner curvature.

[0139] In a specific implementation, a through hole 162 may be formed at the end of the screw rod 160 away from the extension arm 183 .

[0140] Furthermore, a surface of the through hole 162 that contacts the deformation portion 119 has an inner curvature, so that the deformation portion 119 disposed through the through hole 162 can rotate smoothly on the first plane.

[0141] For example, the via hole 162 may be a square hole with an inner curvature.

[0142] For another example, the via hole 162 may be opened along the lateral direction (±x direction in the figure).

[0143] In a specific implementation, the deformation portion 119 may be an elastic connecting steel sheet, and protrusions 159 are respectively provided at both ends of the deformation portion 119 along the extension direction.

[0144] After the adjusting nut 161 is screwed to the through screw 160, the deformation portion 119 passes through the through hole 162, and both ends of the deformation portion 119 extend into the corresponding insertion portions 156 respectively, and the protrusion 159 is coupled with the corresponding adapter hole 158 to fix the nose pad body 118 and the deformation portion 119 as a whole.

[0145] As the adjusting nut 161 rotates up and down on the through screw 160, the opening and closing degree of the deformation portion 119 can be changed, thereby adjusting the shape of the first surface 118a of the nose pad body 118, so that the deformation degree of the nose pad body 118 is more in line with the raised height of the nose bridge.

[0146] While the nose pad body 118 continues to close with the deformation portion 119 , both ends of the deformation portion 119 can extend out from the opening 157 to ensure that the nose pad body 118 can always fit well with the deformation portion 119 .

[0147] Specifically, the starting point for measuring the face of the glasses fitting and measuring frame 1 in this embodiment is the midline of the bridge of the nose, so the design of the nose pad assembly 11 focuses on stability and comfort. In view of the physiological characteristics of Asians, the height of the midline of the bridge of the nose is relatively low, so in this embodiment, the nose pad 112 can better fit the bridge of the nose through the cooperation of the nose pad body 118, the deformation part 119, the through screw 160 and the adjustment nut 161.

[0148] In a specific implementation, since the surface of the through hole 162 that contacts the deformation portion 119 has an inner curvature, the nose pad body 118 can rotate in the first plane around the portion where the deformation portion 119 contacts the through hole 162 to adjust the inclination angle of the nose pad 112 .

[0149] In a specific implementation, continue to refer to Figure 1 and Figure 7 Any one of the first temple 12 and the second temple 13 may include: a temple body 120, connected to the first end 10a or the second end 10b of the main beam 10; an ear hook 121, connected to the temple body 120 and movable forward and backward relative to the temple body 120 along the extension direction of the temple body 120; and a first locking portion 122, used to limit the relative movement between the ear hook 121 and the temple body 120.

[0150] For example, the temple body 120 can be a hollow frame, and a reading indication point is set at a suitable position of the frame. Correspondingly, the straight section of the ear hook 121 can extend into the hollow frame and move forward and backward in the frame, and the straight section of the ear hook 121 can be provided with a scale line. Thus, the overall length of the temple can be adjusted by moving the ear hook 121. After the ear hook 121 is moved to a suitable position, the ear hook 121 and the temple body 120 are locked by the first locking part 122 to prevent the two from unexpected displacement during the optometry process. At this time, the length of the temple can be read by the reading indication point and the scale line on the ear hook 121.

[0151] In one specific implementation, reference Figure 2 and Figure 4 The glasses fitting and measuring frame 1 may further include: a second transverse adjustment member 17, which is connected to the main beam 10 and can move relative to the main beam 10 along a transverse direction (±x direction in the figure), and the first temple 12 is connected to the main beam 10 through the second transverse adjustment member 17, and the first temple 12 moves with the second transverse adjustment member 17.

[0152] For example, the main beam 10 may also include: a fifth screw rod 170, which is arranged on one side of the main beam body 100 close to the first end 100a along the lateral direction (±x direction shown in the figure); a fourth spiral transmission part 171, which is screwed to the fifth screw rod 170. As the fifth screw rod 170 rotates, the fourth spiral transmission part 171 moves along the fifth screw rod 170, and the second lateral adjustment member 17 is connected to the fourth spiral transmission part 171.

[0153] One end of the fifth screw rod 170 can extend into the main beam body 100, and the other end can be connected to the fourth knob 167. Rotating the fourth knob 167 can cause the fifth screw rod 170 to rotate around its own axis.

[0154] The extension direction of the second transverse adjustment member 17 can be parallel to the longitudinal direction (±z direction in the figure), the upper end of the second transverse adjustment member 17 along the +z direction is connected to the fourth screw transmission part 171, and the lower end of the second transverse adjustment member 17 along the -z direction is connected to the first temple 12.

[0155] The second transverse adjustment member 17 and the fourth spiral transmission part 171 may be integrally formed. Figure 8 and Fig. 9 shown.

[0156] In a specific implementation, the fifth screw rod 170 may be provided with a through hole (not shown) along the axial direction, and the second screw rod 101 is disposed in the through hole of the fifth screw rod 170. Thus, by sleeve-arranging the fifth screw rod 170 outside the second screw rod 101 and arranging them together in the main beam body 100, the diameter of the main beam body 100 can be minimized, which is beneficial to the miniaturization design of the device.

[0157] In a specific implementation, the eyeglass fitting and measuring frame 1 may further include: a second locking portion 172 for limiting the relative movement between the second transverse adjustment member 17 and the main beam 10 .

[0158] For example, a through hole (not shown) may be provided at the top of the main beam body 100 in the +z direction near the first end 100a, and the second locking portion 172 extends from the through hole into the main beam body 100. The second locking portion 172 may be a screw, and when the screw is rotated in the -z direction to interfere with the fifth screw rod 170, the fifth screw rod 170 is locked, so that the second transverse adjustment member 17 can no longer move relative to the main beam 10 in the transverse direction (±x direction in the figure).

[0159] Similarly, the eyeglass fitting and measuring frame 1 may further include: a third transverse adjustment member 18, wherein the third transverse adjustment member 18 is connected to the main beam 10 and can move relative to the main beam 10 along a transverse direction (±x direction in the figure), and the second temple 13 is connected to the main beam 10 through the third transverse adjustment member 18, and the second temple 13 moves with the third transverse adjustment member 18.

[0160] For example, the main beam 10 may further include: a sixth screw rod 180, wherein the sixth screw rod 180 is disposed on one side of the main beam body 100 close to the second end 100b along the transverse direction (±x direction in the figure);

[0161] The fifth spiral transmission part 181 is screwed to the sixth screw rod 180 . As the sixth screw rod 180 rotates, the fifth spiral transmission part 181 moves along the sixth screw rod 180 . The third transverse adjustment member 18 is connected to the fifth spiral transmission part 181 .

[0162] One end of the sixth screw rod 180 can extend into the main beam body 100, and the other end can be connected to the fifth knob 168. Rotating the fifth knob 168 can cause the sixth screw rod 180 to rotate around its own axis.

[0163] The extension direction of the third transverse adjustment member 18 can be parallel to the longitudinal direction (±z direction in the figure), the upper end of the third transverse adjustment member 18 along the +z direction is connected to the fifth spiral transmission part 181, and the lower end of the third transverse adjustment member 18 along the +z direction is connected to the second temple 13.

[0164] The third transverse adjustment member 18 and the fifth spiral transmission part 181 may be integrally formed. Figure 8 and Fig. 9 shown.

[0165] In a specific implementation, the sixth screw rod 180 may be provided with a through hole (not shown) along the axial direction, and the third screw rod 104 is disposed in the through hole of the sixth screw rod 180 , so that the diameter of the main beam body 100 can be minimized, which is beneficial to the miniaturized design of the device.

[0166] The eyeglass fitting and measuring frame 1 may further include: a third locking portion 182 for limiting the relative movement between the third transverse adjustment member 18 and the main beam 10 .

[0167] For example, a through hole (not shown) may be provided at the top of the main beam body 100 in the +z direction near the second end 100b, and the third locking portion 182 extends from the through hole into the main beam body 100. The third locking portion 182 may be a screw, and when the screw is rotated in the -z direction to interfere with the sixth screw rod 180, it locks the sixth screw rod 180, so that the third transverse adjustment member 18 can no longer move relative to the main beam 10 in the transverse direction (±x direction in the figure).

[0168] Thus, the spacing between the first temple 12 and the second temple 13 along the transverse direction (±x direction in the figure) is adjustable through the second transverse adjustment member 17 and the third transverse adjustment member 18, which is conducive to adjusting the temples to a suitable position according to the head circumference width of the test subject. In addition, the width value of the test subject's head circumference (i.e., the cranial temporal distance) can be read based on the scale lines drawn on the main beam 10.

[0169] In one specific implementation, reference Figure 1 , Figure 7 , Figure 8 and Fig. 9 The eyeglass fitting and measuring frame 1 of this embodiment may further include: a rotating connector 19, through which the first temple 12 and the second temple 13 are respectively connected to the first end 10a and the second end 10b of the main beam 10.

[0170] Specifically, the rotating connector 19 can be used to drive the temple to rotate within a preset angle range in a rotation plane, wherein the rotation plane is perpendicular to the lateral direction (±x direction in the figure).

[0171] For example, the temple body 120 can be connected to the main beam 10 via the rotating connector 19 .

[0172] Therefore, according to the individual characteristics of the height of the ear position of a person, the downward inclination angle of the frame surface can be adjusted by rotating the connecting piece 19, and the two temples can be adjusted independently, which is of great significance in the later correction process of the eyeglass frame.

[0173] In a specific implementation, the preset angle range may be [-10, 30] degrees, and the preset angle refers to the angle between the extension direction of the temple and the depth direction (±y direction in the figure).

[0174] For example, when the extension direction of the temple is parallel to the depth direction (±y direction in the figure), that is, the extension direction of the temple is perpendicular to the longitudinal direction (±z direction in the figure), the preset angle is 0 degrees.

[0175] For another example, when the temple rotates along the +z direction driven by the rotating connector 19, the value of the preset angle is a positive number, and the value increases as the temple rotates in the +z direction.

[0176] For another example, when the temple rotates along the -z direction driven by the rotating connector 19, the value of the preset angle is a negative number, and the value increases as the temple rotates in the -z direction.

[0177] In practical applications, those skilled in the art can adjust the preset angle range as needed. For example, the preset angle range can also be [-45, 45] degrees, [-15, 30] degrees, [-90, 90] degrees, etc.

[0178] In a specific implementation, the rotating connector 19 may include: a connecting portion 192, which can rotate around a fulcrum, and the connecting portion 192 is fixedly connected to the temple to drive the temple to rotate; and a driving portion, which is used to drive the connecting portion 192 to rotate around the fulcrum.

[0179] In a specific implementation, the driving part may include: a driving part screw 190, which is arranged on the second lateral adjustment member 17 (or the third lateral adjustment member 18) along the longitudinal direction (±z direction shown in the figure); a driving part spiral transmission part 191, which is screwed to the driving part screw 190. As the driving part screw 190 rotates, the driving part spiral transmission part 191 moves along the driving part screw 190 to drive the connecting part 192 to rotate around the fulcrum.

[0180] In a specific implementation, one end of the connecting portion 192 may have a convex head portion 193 protruding outward, and the convex head portion 193 extends into a notch 194 opened on the spiral transmission portion 191 of the driving portion to couple with the notch 194, so that the spiral motion of the driving portion screw 190 can be converted into linear motion via the spiral transmission portion 191 of the driving portion and then transmitted to the connecting portion 192.

[0181] In a specific implementation, the eyeglass fitting and measuring frame 1 may include a mounting shaft fixed to the main beam 10, the mounting shaft has a mounting portion 179, the connecting portion 192 is pin-connected to the mounting portion 179 via a transverse inner pin 195, and the transverse inner pin 195 is the fulcrum.

[0182] For example, the mounting axis may be formed by the second transverse adjustment member 17 (or the third transverse adjustment member 18 ).

[0183] In a specific implementation, the transverse inner pin 195 passes through the locking hole 196 opened in the connecting portion 192 and the hinge hole 197 opened in the mounting portion 179 in sequence to hinge the connecting portion 192 to the mounting portion 179, and the connecting portion 192 can rotate in the rotation plane with the transverse inner pin 195 as a fulcrum.

[0184] Thus, the driving knob 177 connected to the driving screw 190 is rotated, and the driving spiral transmission part 191 moves in the longitudinal direction. Under the coupling action of the notch 194 and the convex part 193, the connecting part 192 is driven to rotate in the rotation plane with the fulcrum locked by the horizontal inner pin 195 as the axis.

[0185] Furthermore, the connecting portion 192 and the temple body 120 are connected and locked via the straight pin 198, thereby driving the temple portion to produce a linkage effect, causing the frame surface to change its tilt angle.

[0186] For example, the connecting portion 192 is provided with a second connecting hole 173 along the longitudinal direction, and the temple body 120 is provided with a first connecting hole 169 adapted thereto along the longitudinal direction, and the length of the temple body 120 along the longitudinal direction may be less than the length of the connecting portion 192 along the longitudinal direction. During assembly, the temple body 120 extends into the connecting portion 192 and makes the positions of the first connecting hole 169 and the second connecting hole 173 coincide, and the straight pin 198 passes through the second connecting hole 173 and the first connecting hole 169 in sequence, so as to realize the fixed connection between the connecting portion 192 and the temple body 120.

[0187] In a specific implementation, the mounting portion 179 may be provided with an angle dial and an inclination angle pointer 199 for indicating the rotation angle (ie, the inclination angle) of the first temple 12 (or the second temple 13) on the rotation plane.

[0188] Specifically, the tilt angle pointer 199 is coaxially arranged with the transverse inner pin 195 to ensure that the tilt angle pointer 199 can rotate synchronously when the temple rotates, so as to accurately indicate the rotation angle of the temple.

[0189] For example, the tilt angle pointer 199 may have a slot 199a, and the locking hole 196 of the connecting portion 192 may have a matching fixing bayonet 199b. The mounting portion 179 may have a first surface 17a and a second surface 17b opposite to each other, the connecting member 192, the driving portion screw 190 and the driving portion spiral transmission portion 191 may be located on the first surface 17a, and the tilt angle pointer 199 and the angle plate may be located on the second surface 17b.

[0190] After the tilt angle pointer 199 passes through the hinge hole 197 from the second surface 17b, the slot 199a is locked with the fixed bayonet 199b of the connecting portion 192, and the transverse inner pin 195 passes through the locking hole 196 and the hinge hole 197 from the first surface 17a in sequence and then couples with the tilt angle pointer 199, so as to achieve the effect of locking the tilt angle pointer 199 and the connecting portion 192. Thus, during the rotation of the rotation plane, the first temple 12 or the second temple 13 drives the tilt angle pointer 199 to rotate synchronously, making it possible to read the angle between the first temple 12 or the second temple 13 and the depth direction.

[0191] By using the eyeglass fitting and measuring frame 1 described in this embodiment, the pupil distance and visual axis distance between the eyes of the test subject can be measured synchronously during the optometry process. Its working principle is to use the basic theory of face recognition and optometry theory as the basis, based on the instrument to fix the midline of the nose bridge, combined with the modulation behavior of the auxiliary lens, so that the optical center of the lens is geometrically positioned in the frame, and its accuracy can reach an optical element that meets the physiological needs of the eyeball.

[0192] Taking the design of progressive multifocal lenses as an example, the progressive multifocal lenses can be divided into several areas: far-field use, near-field use, and zoom transition. When a person's eyes change from looking far to looking near, the line of sight convergence and line of sight downward movement will be used, and the line of sight change trajectory at this time needs to be tracked and identified. The glasses fitting measurement frame 1 of this embodiment can accurately track and identify the line of sight change trajectory of the human eye during this period.

[0193] The basis of face recognition is to use the geometric features of the human face as the measurement points. The main test targets of this project are the width of the human head circumference, the horizontal distance between the pupil centers of both eyes and the vertical difference, the height of the bridge of the nose, the height of the ear, the distance between the ear and the eye, and other various glasses fitting parameters. The glasses fitting measurement frame 1 described in this embodiment can accurately measure the aforementioned various glasses fitting parameters.

[0194] In a typical application scenario, the above Figures 1 to 9 The optometry process of the glasses fitting and measuring frame 1 may include the following steps:

[0195] First, the nose pad assembly 11 and the rotating connector 19 can be adjusted so that the nose pad 112 fits better to the nose bridge of the test subject. The extension direction of the nose pad assembly 11 is basically parallel to the longitudinal direction, and the extension direction of the main beam body 100 is basically parallel to the transverse direction.

[0196] Under the premise of determining the nose pad midline reference and the height reference, adjust the fifth screw 170 and the sixth screw 180 to adjust the second transverse adjustment member 17 and the third transverse adjustment member 18 to a suitable position, and then respectively lock the positions of the two temples along the transverse direction through the second locking portion 172 and the third locking portion 182, and record the position information of the second transverse adjustment member 17 and the third transverse adjustment member 18 on the main beam body 100, and the position information represents the head circumference width of the test subject. Indicator blocks can be respectively provided on the second transverse adjustment member 17 and the third transverse adjustment member 18 to cooperate with the scale lines on the main beam body 100 to indicate the position information.

[0197] Then, use Fig.10 The cross-slit lens 2 (also referred to as a cross reference test piece) is inserted into the lens bearing portion 143 of the first lens holder 14 at an angle of 45° along the +x and +z directions, and / or, is inserted into the lens bearing portion 143 of the second lens holder 15 at an angle of 45° along the -x and +z directions. The cross-slit lens 2 is fixed to the lens bearing portion 143 by using the elastic guide portion 155 in combination with the buckle portion 153. In addition, ensure that the first reference scale 20 of the cross-slit lens 2 is aligned with the horizontal and vertical scales 178 of the lens bearing portion 143, as shown in FIG. Fig.13 shown.

[0198] In a specific implementation, the cross-slit lens 2 may include a first lens body 25, and the periphery of the first lens body 25 may be covered with a first frame 21 for protection. A first handle 22 may be formed on one side of the first frame 21 for the user to take.

[0199] Specifically, the first lens body 25 can be made of opaque resin material, and the first frame body 21 can be made of engineering plastics.

[0200] Furthermore, a pupil positioning hole 23 with a diameter of 5 mm may be formed at the center of the first lens body 25. In practical applications, the positive and negative errors of the diameter of the pupil positioning hole 23 may be within 0.06 mm.

[0201] Furthermore, the first lens body 25 may be provided with orthogonal cross-shaped slits 24 , and the two slits 24 are orthogonal at the pupil locating hole 23 .

[0202] For each slit 24 , the length L1 of the slit 24 may be 14 mm, and the positive and negative errors may be within 0.05 mm. The slit 24 may be a through groove that penetrates through two surfaces of the first lens body 25 .

[0203] For each crack 24 , the width D2 of the crack 24 may be 1 mm, and the positive and negative errors may be within 0.02 mm.

[0204] That is, the first lens body 25 is shielded from light in the area other than the pupil positioning hole 23 and the cross-shaped slit 24 .

[0205] Furthermore, the end 24a of the slit 24 away from the pupil locating hole 23 may be arc-shaped, the diameter of the semicircle may be 1 mm, and the positive and negative errors may be within 0.04 mm.

[0206] Further, the first reference scale 20 provided on the first frame 21 may correspond to the cross-shaped crack 24. That is, the extending directions of the cross-shaped crack 24 coincide with the first reference scale 20 respectively.

[0207] After the cross-slit lens 2 is fixed, the second screw 101 and the third screw 104 are adjusted to move the first lens holder 14 and the second lens holder 15 in the lateral direction (±x direction in the figure), so as to adjust the pupil center of the subject. At this time, if the reflection point where the corneal vertex is linearly illuminated is at the center of the pupil positioning hole 23, the position of the first lateral adjustment member 142 on the main beam body 100 can be used to observe and measure the parameters of the pupil distance of one eye or two eyes.

[0208] Furthermore, if the reflective point is deviated, the position of the deviation can be observed in the cross-shaped slit 24, and timely adjustments can be made (such as adjusting the first screw 145, the second screw 101 and / or the third screw 104). Through the scales on the longitudinal adjustment member 141 and the main beam body 100, the vector difference in the geometric dimensions between the pupils of the test subject's eyes can be observed.

[0209] To improve the accuracy, the horizontal reference can be lowered or raised through the lens bearing portion 143 so that the reflective point enters the crack 24 .

[0210] Thus, the condition of the test subject's corneal reflection point at the center of the pupil positioning hole 23 can be observed. If there is a deviation, the slit 24 can be used to make quantitative adjustments in the horizontal and vertical dimensions (corresponding to the horizontal direction and the longitudinal direction respectively).

[0211] Based on the determination of the interpupillary distance between the two eyes, Fig.11The pinhole lens 3 (which may be referred to as a pinhole reference measuring piece) is inserted into the lens carrier 143 at the same 45° angle. Also, ensure that the second reference scale 30 of the pinhole lens 3 is aligned with the horizontal and vertical scales 178 of the lens carrier 143, as shown in FIG. Fig.14 shown.

[0212] Specifically, the pinhole lens 3 may include: a second lens body 31 , a through hole 33 may be opened at the center of the second lens body 31 ; and a second frame 32 , covering the outer side of the second lens body 31 to play a protective role.

[0213] Furthermore, the radius of the through hole 33 may be 0.48 to 0.52 mm.

[0214] For example, the second lens body 31 may be made of a light-proof resin material, and the second frame body 32 may be made of engineering plastics.

[0215] A second handle 35 may be formed on one side of the second frame body 32 for the user to hold.

[0216] The number of the through hole 33 may be one, and the area of ​​the second lens body 31 other than the through hole 33 is light-shielded.

[0217] In a specific implementation, the second lens body 31 may be provided with a first scale scratch 36 and a second scale scratch 37 , and the first scale scratch 36 and the second scale scratch 37 are orthogonal at the through hole 33 .

[0218] In a specific implementation, the end of the first scale mark 36 may have scales 34 , and the interval D1 of the scales 34 is 1 mm.

[0219] In a specific implementation, the second frame 32 may be provided with a second reference scale 30, and the second reference scale 30 corresponds to the first scale mark 36 and the second scale mark 37. That is, the extension directions of the first scale mark 36 and the second scale mark 37 respectively coincide with the second reference scale 30. The second reference scale 30 may include a horizontal reference scale and a vertical reference scale.

[0220] By using the pinhole imaging principle, the optical axis system of the eyeball can be formed with the center point of the retinal fovea in theory, that is, the line of sight structure of the eye. Due to the kappa angle of the human eye, the point of departure of most people's line of sight on the upper surface of the cornea will deviate from the center position of the vertex of the cornea, and this deviation can be verified by the pinhole lens 3.

[0221] Furthermore, the through hole 33 can also be used to increase the depth of field. In the case of mild refractive error, without adding a corrective lens, the detection operation can be completed based on the pinhole lens 3. For those with moderate to high refractive error, a single ball lens (not shown) can be used for auxiliary detection. The front and rear sides of the lens bearing part 143 of the eyeglass fitting measurement frame 1 described in this embodiment have three inserting slots (i.e., the limiting slots 154) for multiple lenses to be used together.

[0222] When both eyes look at a single target in the distance through the through hole 33, the visual center of the brain will guide the fusion operation. If two images are seen, it means that the fusion mechanism of the macula center is not sound and there is a tendency of strabismus or latent strabismus, so it is necessary to start checking the binocular vision function.

[0223] The variable angle of binocular fusion can also be found by moving the horizontal and / or vertical vectors (i.e., the positions in the horizontal and longitudinal directions) of the pinhole lens 3 by adjusting the first screw 145, the second screw 101, and / or the third screw 104. When reconstructing binocular fusion, the required movement amount is observed, and the variable at this time can be provided as the angle conversion of kappa.

[0224] Therefore, the visual axis base point of the human eye and the difference between the visual axis base points of the binocular eyes can be measured through the pinhole lens 3.

[0225] In a typical application scenario, when fitting progressive multifocal lenses, it is usually necessary to locate the distance center and near center on the lens surface. However, due to heterophoria or poor or abnormal coordination and synchronization between accommodation and convergence, the near center usually causes deviation in the convergence intersection position. In the lens manufacturing process, especially in high-end personalized design, the parameter content option needs to specify the monocular near vision center inward displacement. At this time, it becomes important to measure the downward angle projected by the eye's line of sight.

[0226] Fig.12 The cross-hole lens 4 shown (which may be called a cross-star lens or a cross-hole test lens) provides a testing method for this operation. The design principle of the cross-hole lens 4 may be that Fig.10 On the basis of the cross-slit lens 2 shown, a peephole 40 with a radius of 1.5 mm is provided at the end 24a of one of the slits 24, and the movement trajectory of the reflective point on the cornea can be observed through the pair of peepholes 40. Among them, the peephole 40 located above the illustrated angle is used as the distance coordinate positioning, and the peephole 40 below is used as the projection point position of the lower viewing angle.

[0227] The positive and negative errors of the radius of the peephole 40 may be within 0.02 mm.

[0228] Specifically, the cross-shaped fissure 24 may include a first fissure 241 and a second fissure 242. Fig.15 When the cross-hole lens 4 is mounted on the glasses fitting and measuring frame 1, the extension direction of the first slit 241 is parallel to the longitudinal direction (±z direction in the figure), and the extension direction of the second slit 242 is parallel to the transverse direction (±x direction in the figure).

[0229] Furthermore, the peepholes 40 are provided at both ends of the first slit 241 along the extension direction. Fig.15 The peephole 40 located at the top along the longitudinal direction (±z direction as shown in the figure) is used for remote coordinate positioning, and the peephole 40 located at the bottom along the longitudinal direction (±z direction as shown in the figure) is used as the projection point position of the lower viewing angle.

[0230] Furthermore, the first lens body 25 is shielded from light in areas other than the pupil positioning hole 23 , the first slit 241 , the second slit 242 and the peephole 40 .

[0231] In a variation, the shape of the peephole 40 can be rectangular, polygonal, etc.

[0232] Taking the aforementioned adjustment base point based on the cross-slit lens 2 as a reference, when the subject is doing close-range work, due to the collective effect of the eye axes of both eyes, the degree of adduction of the visual axis varies from person to person. By observing and adjusting the position of the corneal reflection point in the peephole 40, the change in the inward movement trajectory of the subject's eye axis in the close-range state can be measured.

[0233] The advantage of the glasses fitting and measuring frame 1 described in this embodiment is that it can be adjusted up and down at the vertical reference position. This is used to judge which type of lens with a gradient channel length is suitable for the wearer. The channel length of a progressive focus lens usually has three specifications: long, medium and short.

[0234] In a desktop environment, the reflective mirror effect of the mirror can be used to track in real time whether the corneal reflection point of the person being tested is in the channel of the cross fissure. If there is any deviation, it can be adjusted in time.

[0235] When the glasses fitting and measuring frame 1 is worn on the face, it is necessary to observe that the rear surface of the test piece should be kept at a position of 12 mm from the front apex of the cornea.

[0236] Specifically, the pin 114 can be rotated to move the nose pad assembly 11 forward and backward on the first plane, so that the vertical surface of the lens bearing portion 143 is perpendicular to the cornea in front of the eye.

[0237] However, human eyes have a certain downward viewing angle. At this time, the inner inclination of the entire mirror surface can be adjusted by the rotating connector 19. When adjusted to a suitable angle, the frame scale of the rotating connector 19 will indicate the downward inclination angle of the first temple 12 and the second temple 13. The inclination angle pointer 199 can be used as a fulcrum pointer of the downward inclination lever.

[0238] In a typical application scenario, the height of a person's ear is individual, and the downward tilt angle of the frame varies due to different ear positions. Most individuals also have left and right ear deviations. In the later correction process of the glasses frame, understanding the height of the ear is of great clinical significance.

[0239] The ear position is not only high or low, but also front or back. The head shape will affect the front and back position of the ear position. Through the sliding rod function of the temple body 120 and the ear hook 121, the ear position of the testee can be measured to determine the specifications of the frame leg length required for fitting the glasses. At the same time, the first locking portion 122 can be used to fix the overall test frame to improve the stability of the overall test frame.

[0240] The common methods for measuring pupil distance are all carried out in a passive manner, and the accuracy of the measurement depends on the user of the method. The apparatus of the present invention can be used on the basis of combining active and passive methods, with subjective facts as a guide, and the method is more clinically practical.

[0241] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
