  With reference to the drawings, the lens for electronic glasses and the one for electronic glasses according to the present invention will be described below. However, it should be noted that the technical scope of the present invention is not limited to these embodiments, but extends to the invention described in the claims and equivalents thereof.

  FIG. 1 is a partial schematic view of the electronic glasses 1.

  As shown in FIG. 1A, an electronic spectacle 1 includes a spectacle frame 2, an armored portion 3, a hinge 4, a temple 5, a bridge 6, and a pad 7. The spectacle frame 2 incorporates a lens 100 for electronic spectacles. It is. The armor section 3 includes spring connectors 10 and 20 for electrical connection with the liquid crystal lens structure 50 of the electronic spectacle lens 100, a voltage supply section 30 including a battery as a power supply section connected to the spring connectors 10 and 20, and a dip switch 31. Etc. are built-in.

  FIG. 1B is a diagram showing the direction of the spring connectors 10 and 20 from the inside of the spectacle frame 2. As shown in FIG. 1B, the spring connectors 10 and 20 are disposed so as to be insertable into a first recess 113 and a second recess 123 of an electronic spectacle lens 100 described later.

  As will be described later, a liquid crystal lens structure 50 including a first transparent electrode 101 disposed on the surface of the Fresnel lens and a second transparent electrode 102 facing the first transparent electrode 101 is provided at the center of the electronic spectacle lens 100. Is formed. When no voltage is applied between the first transparent electrode 101 and the second transparent electrode 102, the liquid crystal lens structure 50 does not operate, and the electronic spectacles 1 can obtain the lens power that the electronic spectacle lens 100 originally has. When a predetermined voltage is applied from the voltage supply unit 20 between the first transparent electrode 101 and the second transparent electrode 102, the liquid crystal lens structure 50 operates as a lens having a predetermined power. In a portion where the lens structure 50 is present, the liquid crystal lens structure 50 operates so that the focal length of the lens that the electronic spectacle lens 100 originally has is variable.

  For example, when the electronic spectacle lens 100 itself has a lens shape capable of obtaining a power that focuses on a far point, and the liquid crystal lens structure 50 does not operate, the electronic spectacles act as a far point spectacle, and the liquid crystal lens It can be envisaged that when the structure 50 is operated, the electronic glasses are designed to act as near-point glasses. If ON / OFF of voltage application to the liquid crystal lens structure is performed by the dip switch 31 of the electronic glasses 1, it is possible to provide the bifocal electronic glasses 1 that can be arbitrarily switched by the dip switch 31. . Note that the types of spectacles that can be provided by the electronic spectacle lens are not limited to those described above, but various types, for example, hyperopic electronic glasses that can switch the power for hyperopia in multiple stages, and multiple levels of myopia power. It can be applied to astigmatism or presbyopia, which can be switched with

  2 and 3 are diagrams for explaining the electronic spectacle lens 100. FIG.

  FIG. 2A shows an electronic spectacle lens 100 ′ before edging at a dotted line B by matching the outer shape of the electronic spectacle lens 100 mounted on the electronic spectacle 1 shown in FIG. 1 with the spectacle frame 2 of the electronic spectacle 1. FIG. 2B is a side view of the electronic spectacle lens 100 ′ before edging.

  3A shows the first transparent substrate 110, and FIG. 3B shows the second transparent substrate 120. The first transparent substrate 110 and the second transparent substrate 120 are columnar substrates. The first transparent substrate 110 and the second transparent substrate 120 are processed so that the outer shape has a lens shape (for example, a concave lens) after the sealing member 131, the liquid crystal layer 130, and the like are bonded to each other. As shown to (a), it becomes the lens 100 'for electronic spectacles before edging. Details of the manufacturing method will be described later with reference to FIG.

  As shown in FIG. 3A, a first recess 113 is formed on the first transparent substrate 110 on the side connected to the second transparent substrate 120. In addition, on the Fresnel lens structure 116 disposed on the first transparent substrate 110, the first transparent electrode 111 formed of ITO (indium tin oxide) as a material by a sputtering method and the first transparent electrode 111 are connected. A first connection line 112 is also arranged.

  As shown in FIG. 3B, the second transparent substrate 120 has a second recess 123 formed on the side connected to the first transparent substrate 110. The first recess 113 is disposed at a position facing the second connection line 122, and the second recess 123 is disposed at a position facing the first connection line 112. On the second transparent substrate 120, a second transparent electrode 121 formed of ITO by a sputtering method and a second connection line 122 connected to the second transparent electrode 121 are disposed.

  In addition, since the shape of the 1st transparent substrate 110 and the 2nd transparent substrate 120 which formed the recessed part in the step before forming a transparent conductive film etc. is the same, the process of film-forming on each board | substrate is also the same. A process can be used, and formation of the lens 100 'for electronic glasses before edging can be easily performed at a relatively low cost.

  As shown in FIG. 2B, the first spring connector 10 provided on the spectacle frame 2 is inserted into the second recess 123 from the end side of the electronic spectacle lens 100 and is arranged inside the second recess 123. The first connection line 112 is contacted. The side surface of the tip 11 of the first spring connector 10 is pressed against the first connection line 112 disposed inside the second recess 123 by the spring spring built in the first spring connector 10. Conductivity with one connection line 112 is ensured (see FIG. 6A).

  As shown in FIG. 2 (b), the second spring connector 20 provided on the spectacle frame 2 is inserted into the first recess 113 from the end side of the electronic spectacle lens 100 and is arranged inside the first recess 113. The second connection line 122 is contacted. Since the side surface of the distal end portion 21 of the second spring connector 20 is pressed against the second connection line 122 arranged inside the first recess 113 by the spring spring built in the second spring connector 20, the second spring connector 20 and the second spring connector 20 Conductivity with the two connection lines 122 is ensured (see FIG. 6A).

  In addition, although the 1st recessed part 113 and the 2nd recessed part 123 were each formed in the rectangle of length w1, the length and shape of the 1st recessed part 113 and the 2nd recessed part 123 are not limited to these, For example, shape May be other polygonal shapes such as circular, elliptical, triangular, etc. Further, the width of the recess can be appropriately selected according to the diameter of the spring connector to be inserted.

  FIG. 4 is a cross-sectional view taken along the line AA ′ of FIG.

  As shown in FIG. 4, the electronic spectacle lens 100 includes a first transparent substrate 110, a second transparent substrate 120, a liquid crystal layer 130 sandwiched between the first and second transparent substrates 110 and 120, and a seal member 131, and the like. Consists of As the liquid crystal layer 130, homogeneous alignment type liquid crystal is used, but vertical alignment type liquid crystal or twisted nematic liquid crystal may be used.

On the first transparent substrate 110, a first gas barrier layer 114 (SiO ₂ , film thickness 200 nm) for preventing gas generated from the transparent substrate from entering the liquid crystal layer 130, a Fresnel lens structure 116, and a Fresnel lens structure 116. A first transparent electrode 111 (ITO, film thickness 50 nm) disposed above, a first alignment film 115 (film thickness 50 nm) disposed on the first transparent electrode 111, and the like are disposed. Note that the first gas barrier layer 114 may be disposed on the Fresnel lens structure 116.

On the second transparent substrate 120, a second gas barrier layer 124 (SiO ₂ , thickness 200 nm) for preventing the gas generated from the transparent substrate from entering the liquid crystal layer 130, and the transparent facing the first transparent electrode 111. A second transparent electrode 121 (ITO, film thickness 50 nm) that is a planar electrode, a second alignment film 125 (film thickness 50 nm) disposed on the second transparent electrode 121, and the like are disposed.

  In order to keep the distance between the first transparent electrode 111 and the second transparent electrode 121 constant, a plurality of spacers (diameter: 10.5 μm) made of resin or silica are arranged in the seal member 131 (see FIG. Not shown). The outer peripheral portion of the sealing member 131 is filled with a transparent resin 134.

  The first and second transparent substrates 110 and 120 use columnar polycarbonate having a thickness of 5 mm as a material, but are not limited to the thickness, and glass may be used as a material. The Fresnel lens structure 116 uses acrylic as a material, but includes a cyclic olefin-based transparent resin, a radical polymerization type acrylic US cured resin, a chaotic polymerization type epoxy US cured resin, a thermosetting resin, and an inorganic-organic material. An optical material such as a hybrid material may be used.

  In the figure, w2 indicates the portion of the liquid crystal lens structure 50. In the example of FIG. 4, w2 = 20 mm. In the figure, w3 indicates the external dimensions of the electronic spectacle lens 100 ′ before edging. In the example of FIG. = 75 mm. However, the above values are merely examples, and other values can be adopted.

  In FIG. 4, for convenience of explanation, the scales of the thicknesses of the respective substrates and layers are changed, and accordingly, the electronic spectacle lens 100 has a predetermined size as shown in FIG. Note that the lens shape is not described. Further, the above-described values of the thicknesses of the respective substrates and layers are examples, and are not limited to the above values.

  FIG. 5 is a view for explaining the structure of the Fresnel lens surface by the liquid crystal lens structure.

  FIG. 5 shows a cross section of the Fresnel lens surface in the radial direction with the vertex of the Fresnel lens surface (that is, the point of the lens surface on the optical axis) as the origin. In the figure, the horizontal axis indicates the position in the radial direction, and the vertical axis indicates the position in the optical axis direction.

  A dotted line 116 ′ in FIG. 5 represents a lens surface that is a source of lens characteristics of the liquid crystal lens structure. The lens surface is designed as a continuous aspect of the central object with respect to the optical axis, like a general lens. Therefore, by providing a step on the lens surface so that the position along the optical axis of the lens surface is the same as the apex, the cross-sectional shape of the Fresnel structure 116 shown in FIG. 5 is obtained (for convenience, in the drawing). The slope of the Fresnel 116 is a straight line, but is actually a curved line like a dotted line 116 '). As a result, a Fresnel lens surface having a plurality of annular zones separated by steps is formed. Although the Fresnel lens structure 116 in FIGS. 3 to 5 has four annular zones, the number of annular zones is an example, and the invention is not limited to this.

  In the electronic eyeglass lens 100 ′ before edging described above, the electronic eyeglass lens 100 can be processed anywhere between the widths w1 of the first recess 113 and the second recess 123 shown in FIG. A connection with a spring connector can be obtained from the end side of the lens 100 (see FIG. 6A). Therefore, as described in the related art, it is possible to cope with spectacle frames having various shapes without predetermining the outer shape of the electronic spectacle lens 100. In addition, the outer peripheral portion of the seal member 131 is filled with the transparent resin 134 before the edging between the first and second transparent substrates 110 and 120. The transparent resin 134 is formed between the substrates using a capillary phenomenon. Therefore, when the concave portion is provided in advance on the substrate, the transparent resin 134 does not enter the entire concave portion region. Therefore, after the edging, regardless of the outer shape of the electronic spectacle lens 100, the connection line provided corresponding to the position of the recess is always exposed and is electrically connected to the spring connector. It becomes possible.

  FIG. 6 is a diagram illustrating a connection state between the electronic spectacle lens 100 and the spring connector.

  FIG. 6A is an enlarged view of a portion surrounded by a dotted line M of the electronic spectacle lens 100 shown in FIGS. As described above, the side surface of the distal end portion 11 of the first spring connector 10 is pressed against the first connection line 112 disposed inside the second recess 123 by the spring spring built in the first spring connector 10, so that the first Electrical connection between the spring connector 10 and the first connection line 112 is ensured. Similarly, since the side surface of the distal end portion 21 of the second spring connector 20 is pressed against the second connection line 122 disposed inside the first recess 113 by the spring spring built in the second spring connector 20, the second spring connector 20 is ensured between the second connection line 122 and the second connection line 122.

  FIG. 6B shows a modification of the connection portion. In the example of FIG. 6B, the transparent resin 65 is filled inside the first recess 113. The transparent resin 65 is filled up to the place where the tip of the inserted second spring connector 20 reaches. Similarly, the transparent resin 66 is filled inside the second concave portion 123 up to a position where the tip 11 of the first spring connector 10 to be inserted reaches. If there is a space in the recess, an air layer is generated, and the part with the air layer and the part with no air (resin part) are clearly distinguished, which is not desirable when the lens is observed from the outside. May give. Therefore, after the edging of the lens for electronic glasses, a transparent resin is filled from the end of the substrate to the inside of the first recess 113 and the inside of the second recess 123 so as to eliminate such a problem.

  FIG. 6C shows still another modified example of the connection portion. In FIG. 6B, the transparent resin 65 and 66 are filled inside the first recess 113 and the second recess 123, leaving a gap for inserting the tip of the spring connector. However, in the example of FIG. 6C, the conductive material 67 is filled so that the gap into which the tip of the spring connector of FIG. 6B is inserted, that is, the first recess 113 is completely filled. Similarly, the conductive material 68 was filled so as to completely fill the second recess 123. The conductive material 68 and the distal end portion 11 of the first spring connector 10 are in contact with each other, and the conductive material 67 and the distal end portion 21 of the second spring connector 20 are in contact with each other. Note that the conductive material 67 and the conductive material 68 are formed of metal, conductive paste, transparent conductive ink, or the like. By disposing the conductive material 67 and the conductive material 68, the connection line and the spring connector can be more reliably connected. When the conductive material is opaque, it is preferable that the conductive material is disposed at the outermost peripheral position of the electronic spectacle lens 100 so as to be hidden by the spectacle frame 2 as much as possible.

  FIG. 6D shows still another modified example of the connection portion. The difference between the example of FIG. 6D and the example of FIG. 6C is that, in the example of FIG. 6D, the conductive material 68 illustrated in FIG. That is, the first connection portion 183 and the second connection portion 184 that are in contact with the conductive material 67 are formed. In addition, the width formed by the first connection portion 183 and the second connection portion 184 is set to the full width of the end face of the electronic spectacle lens 100. In the example of FIG. 6D, the other parts are the same as in the example of FIG. By forming the first connection portion 183 and the second connection portion 184 widely as described above, it is possible to increase the degree of freedom in arranging the two spring connectors. In addition, the width | variety of the 1st connection part 183 and the 2nd connection part 184 is not limited to this.

  In the example of FIGS. 6B to 6D, the first recess 113 and the second recess 123 are almost filled with a transparent resin or a conductive material, so that no air layer is formed. Therefore, in the examples of FIGS. 6B to 6D, there is no problem due to the formation of the air layer. In the examples of FIGS. 6C and 6D, the conductive material 67 and the conductive material 68 can increase the area in contact with the tip of the spring connector, so that the first connection line 112 and the second connection are connected. It is preferable to make the width of the line 122 as small as possible to make it unnoticeable.

  FIG. 7 is a diagram for explaining a manufacturing process of the electronic spectacle lens 100. Hereinafter, the manufacturing process of the lens for electronic glasses will be described with reference to FIG.

  First, a first recess 113 is formed by cutting in a cylindrical (thickness 5 mm) first transparent substrate 110, and a second recess 123 is cut in a cylindrical (thickness 5 mm) second transparent substrate 120. Form (S10).

  Next, a first gas barrier layer 114 and a second gas barrier layer 124 are formed on the first transparent substrate 110 and the second transparent substrate 120, respectively, with a SiO2 film having a thickness of 200 nm (S11).

  Next, the Fresnel lens structure 116 is disposed on the first transparent substrate 110 (S12). The Fresnel lens structure 116 is separately formed using a UV curable acrylic resin or the like, and is bonded and fixed onto the first transparent substrate 110. However, similarly to the first recess 113, the first transparent substrate may be formed by cutting or the like, or may be formed by integrally molding with the transparent substrate itself by casting or injection molding.

  Next, an ITO film is formed and patterned on the first transparent substrate 110 on which the Fresnel lens structure 116 is disposed, thereby forming the first transparent electrode 111 and the first connection line 112. Similarly, the ITO film is formed and patterned on the second transparent substrate 120 to form the second transparent electrode 121 and the second connection line 122 (S13).

  Next, a first alignment film 115 is formed on the first transparent electrode 111 of the first transparent substrate 110, and a seal member 131 is formed after rubbing. Further, the second alignment film 125 is formed on the second transparent electrode 121 of the second transparent electrode 120 and rubbed. Then, after dropping the liquid crystal forming the liquid crystal layer 130 in the seal member 131, the first transparent substrate 110 and the second transparent substrate 120 are bonded together in a vacuum atmosphere, and the outside of the seal member 131 (the liquid crystal layer is formed). The blank resin (the state in which the lens outer shape is not formed) is completed by filling the transparent resin 134 with the capillary phenomenon in the non-existing portion (S14).

  Next, the outer shape of the blank lens is processed to form a lens shape, and a finished lens (lens 100 ′ for electronic spectacles before edging) is completed (S15). The lens shape is formed on each side, but only one side is called a semi-finished lens.

  Next, the finished lens is edged in accordance with the shape of the spectacle frame 2 to complete the edged lens (lens 100 for electronic spectacles) (S16), and the liquid crystal lens structure 50 and the spring connectors 10 and 20 are electrically connected. As shown in FIG. 5, the electronic spectacles 1 are completed by attaching them to the spectacle frame 2 (S17). If necessary, after the edging (S16), the transparent resins 65 and 66 to the first recess 113 and the second recess 123 as shown in FIGS. 6B to 6D described above, and The conductive materials 67 and 68 are filled, and further, the first connection portion 183 and the second connection portion 184 are formed.

  In the present invention, one of the reasons why a recess (or an opening to be described later) is necessary is when the first transparent substrate 110 and the second transparent substrate 120 are bonded together in a vacuum atmosphere and the resin is filled around the sealing material. In addition, the connection line is also filled with resin, which makes it difficult to conduct from the side surface side of the lens for electronic glasses. In the present invention, by arranging a recess (or an opening described later) at a position corresponding to the connection line, a space for taking electrical conduction from the side of the lens for electronic glasses is secured, and such a problem is solved. doing.

  In the present invention, the term “electronic spectacle lens” in a broad sense includes all of the blank lens, semi-finished lens, finished lens, and lens after edging that have the liquid crystal lens structure 50. In the narrow sense, the term “electronic spectacle lens” refers to, for example, the electronic spectacle lens 100 that is actually attached to the spectacle frame.

  FIG. 8 is a diagram showing a modification of the electron lens 100 ′ before edging.

  In the example of FIGS. 2 and 3, the first recess 113 and the second recess 123 have a “width w <b> 1” that extends to the outer edges of the first transparent substrate 110 and the second transparent substrate 120. However, in the example of FIG. 8, the second recess 140 has a width w4 (<w1) and does not reach the outer edge of the second transparent substrate 120. Although not shown, the first concave portion of the first transparent substrate 110 corresponding to the second transparent substrate 120 shown in FIG. 8 similarly has a width w4. Note that the electronic spectacle lens after edging along the dotted line B has the same configuration as the above-described electronic spectacle lens 100 in the case shown in FIG.

  FIG. 9 is a diagram showing another modification of the electronic lens 100 ′ before edging.

  FIG. 9A shows a plan view of a second transparent substrate constituting another modified example of the electronic lens 100 ′ before edging, and FIG. 9B shows the electronic glasses that are edged from the electronic lens 100 ′. An enlarged view of the end face of the lens 150 is shown.

  In the second transparent substrate 120 shown in FIG. 9A, a recess 152 is also formed in a portion where the second connection line 122 is disposed. The second connection line 122 is formed of ITO by a sputtering method, but can be formed even if there is a three-dimensional shape of the recess 152 due to the wraparound phenomenon of ITO particles. In addition, an enlarged partial cross section of a portion C in FIG. As shown in D, since the tip of the recess 152 is not an acute angle but is rounded, the second connection line 122 is prevented from being disconnected at the recess 152. Although not shown, in the first transparent substrate 110 corresponding to the second transparent substrate 120 shown in FIG. 9, similarly, a recess 151 is formed in a portion where the first connection line 112 is disposed. The tip of the recess 151 is not an acute angle but is rounded.

  As shown in FIG. 9B, when the first transparent substrate 110 and the second transparent substrate 120 are bonded together with a sealant or the like, a recess 152 is disposed at a position facing the first recess 113, and the second recess The recessed part 151 will be arrange | positioned in the position facing 123. FIG. Therefore, the first spring connector 10 and the second spring connector 20 are inserted into the space formed between the first recess 113 and the recess 152 and the space formed between the second recess 123 and the recess 151, respectively. The Here, if the depths of the first concave portion 113 and the concave portion 152 and the second concave portion 123 and the concave portion 151 are appropriately adjusted, the position where the second spring connector 20 is inserted immediately above the position where the first spring connector 10 is inserted. Can be arranged. Therefore, there is an advantage that the positions of the first spring connector 10 and the second spring connector 20 formed on the spectacle frame 2 need not be shifted from each other in the vertical direction as shown in FIG.

  In the enlarged partial cross section D shown in FIG. 9A, the tip of the spring connector is in contact with the first connection line 152 (refer to the location “N”) arranged at the portion where the rounded portion of the recess 152 is formed.
