Description

[0001] Data glasses frame, data glasses and spectacle lens as well as method for assembling data glasses

[0002] The invention relates to a data glasses frame for data glasses, a spectacle lens for data glasses, data glasses, a parts set for obtaining data glasses and a method for assembling data glasses.

[0003] Data glasses are a newly emerging segment of consumer electronics, among others, in which two-dimensional image information is provided on the retina of the human eye.

[0004] Image information on the retina can be generated in a variety of ways. Both scanning and non-scanning systems are common. In scanning systems, the perceived image is generated by temporally modulating both the position and intensity of a quasi-point-like intensity distribution on the retina. An example of a scanning system is described in WO 2014 / 155288 A2. In non-scanning systems, the pixels of an extended display are projected onto the retina simultaneously.

[0005] In addition to providing additional image information, it is often desirable to also allow an unobstructed view of the surroundings (see-through wearables). The image information can preferably be displayed in the user's peripheral field of vision. This requirement prevents solutions that place an opaque imager and associated imaging optics directly in front of the eye. Therefore, the image information is usually generated outside the eye's field of vision, and the generated image is projected in front of the eye using optics in the desired viewing direction.

[0006] Typical data glasses, such as those described in DE 10 2011 007 812 A1 and US 2012 / 0 002 294 A1, comprise an image generator for generating an image, hereinafter also referred to as a display, and a spectacle lens into which an imaging beam path emanating from the image generator is coupled.

[0007] The image generated by the display is coupled into an optical fiber, reflected one or more times within the fiber by total internal reflection, and finally coupled out toward the user's eye via an output region in the lens, allowing the wearer of the data glasses to see a virtual image. The spatial area from which the virtual image is visually perceivable by the user's eye is also called the eyebox.

[0008] The imaging beam path is coupled out toward the eye using a beam-splitting coupling region so that the virtual image is superimposed on the image of the surroundings, allowing the user to perceive the virtual image in addition to the surroundings. An example of a pair of data glasses in which the imaging beam path is guided to an outcoupling structure in the lens by means of total internal reflection is described in DE 10 2013 223 963 A1 and DE 10 2013 223 964 B3.

[0009] To ensure consistently accurate positioning of the display and the lens relative to each other, state-of-the-art smart glasses typically involve gluing the components together to create a permanent, secure connection. For example, the display is glued to a display holder, which is then bonded to the lens via an adhesive bond.

[0010] Currently available smart glasses offer no or only limited correction options tailored to the user's individual needs. This means that smart glasses either offer no vision correction at all, or vision correction is only possible by attaching additional components, such as attachments, which prove to be difficult to handle and aesthetically unappealing, often resulting in poor wearing comfort. Furthermore, smart glasses generally offer no or only limited UV protection and lens tinting, and do not allow for customization of these features.

[0011] Users also expect smart glasses to look like regular glasses and, as a consumer electronics device, to be available through the electronics industry's standard online and retail channels. However, the expertise available in these areas regarding customized vision correction is considered to be limited, making it impossible or insufficient to customize the smart glasses to the user's personal vision correction needs. Consequently, the involvement of opticians and / or ophthalmologists for individual prescriptions for vision correction would also be required, which is often difficult to implement due to time and location constraints.

[0012] In summary, existing solutions have one or more of the following disadvantages:

[0013] Data glasses do not allow for individual vision correction, individual lens tinting or individual UV protection;

[0014] Smart glasses require an additional component (“add-on”) in the form of a “prescription clip” inside the glasses to correct vision, which makes them heavier and looks bulky;

[0015] Depending on the technological concept used, smart glasses require a complex scanning and fitting process for each individual user, lasting up to two hours in a retail store; then, a custom lens is manufactured, which takes a lot of time, and finally, the user must return to the store for a final fitting, which can fail and require a restart of the described process.

[0016] Against this background, the object of the invention is to provide smart glasses and components for smart glasses, as well as a method for assembling smart glasses, which enable the lens to be easily customized, for example, for individual vision correction. Preferably, the effort required to adjust the smart glasses to the user should be approximately equivalent to the effort required to adjust regular glasses.

[0017] This problem is solved by the subject matter of the independent claims. The dependent claims relate to embodiments of these inventive solutions.

[0018] A basic idea of ​​the invention is to provide data glasses whose lenses are easily replaceable, even by people without special training, and can be replaced with a lens that is individually adjusted, e.g., to the user's visual acuity. The display and any other optical elements are reused and remain in their assembled state while the lens is being replaced. To make this possible, the display is not permanently attached to the lens, as has previously been the case.

[0019] For example, the display can be attached to the frame via a holder in a variable position while the lens is inserted into the frame. The positioning of the lens relative to the display can be ensured using guide elements, such as guide pins or alignment pins. This allows for a predetermined positioning and alignment of the lens and display when the frame is closed.

[0020] A first aspect of the invention relates to a smart glasses frame for smart glasses, i.e., smart glasses can be manufactured using the smart glasses frame. The smart glasses frame has a spectacle frame designed to hold and position an interchangeable spectacle lens. Of course, the spectacle frame can also be designed to hold and position multiple spectacle lenses, in particular two spectacle lenses.

[0021] Replaceable lenses mean that the lens can be removed from the smart glasses frame without causing any damage to either the lens or the smart glasses frame and replaced with another lens, e.g., one with a different vision correction. For a more detailed explanation of the lens, please refer to the following sections.

[0022] For this purpose, the spectacle frame can partially or completely enclose the lens(es), as is customary in the trade, wherein the frames are connected to one another by means of a bridge arranged centrally, i.e. connecting the nasal sides of the frames, in order to be able to support the spectacle frame on the nose of a human viewer, so that a positioning of the lenses in front of the human eye is possible.

[0023] Temples can be arranged on the temporal sides of the spectacle frame to allow support on the ears of the human observer, i.e., a user. Other fastening options for the spectacle frame to the user's head are also possible. The temples can be connected to the spectacle frame by means of a hinge to allow the temples to be folded on and off the spectacle frame for space-saving and secure storage. The spectacle frame can, for example, be made of a plastic material or be made of a plastic material, as this is characterized by its low weight and, at the same time, a wide range of design options.

[0024] The smart glasses frame also features a display mechanically connected to the frame. The display serves as the image generator for generating the virtual image. The display can, for example, be mounted directly on the frame. Alternatively, it can be mounted on or in the hinge of the temple, or in the temple itself, so that in these cases the display is connected to the frame via the hinge or temple.

[0025] To connect the display to the eyeglass frame, a display holder can be provided, which is designed to accommodate the display and is in turn connected to the eyeglass frame, e.g., a display holder mount arranged on the eyeglass frame. Furthermore, the data glasses frame has eyeglass frame guide elements designed to position and align the display with respect to the eyeglass lens.

[0026] The eyeglass frame guide elements can be designed, for example, as locating or guiding pins, for example, with a cylindrical shape, or as a corresponding counterpart, i.e., as recesses that accommodate locating or guiding pins. A combination of locating or guiding pins and receiving recesses, or a (partial) other design of the eyeglass frame guide elements, e.g., as ribs or webs, is also possible. The precise geometric design of the guide elements depends on the geometric conditions and the construction of the data glasses frame and the spectacle lens to be inserted into it.

[0027] To enable not only positioning the display but also alignment and, for example, to prevent the display from twisting relative to the lens, at least two spectacle frame guide elements are provided, which can be combined with each other in any way, e.g., in the form of a cylindrical guide pin with a guide rib arranged thereon to ensure a specific alignment of the guide pin in a receiving recess. Preferably, the at least two spectacle frame guide elements should be arranged with the greatest possible distance from each other to enable the most precise positioning and alignment of the display relative to the lens.

[0028] The term "eyeglass frame guide element" means that the guide element is part of the smart glasses frame, in contrast to the "lens guide element" described below, which is part of the lens. The eyeglass frame guide elements can therefore be arranged, for example, on the eyeglass frame, the display, and / or the display holder.

[0029] The frame guide elements are used for the precise positioning and alignment of the display with respect to the lens. This enables simple and non-destructive replacement of the lens, for example by an optician or the user themselves. This makes it possible to obtain data glasses with different lenses, which allow, for example, individual vision correction, individual position of the eyebox depending on the user's pupil position, UV protection, tinting, etc. If, for example, a different vision correction is desired, only the lens needs to be replaced, while the display always remains connected to the frame. In other words, the data glasses frame can continue to be used with the display, thus saving costs and material for a new production that would otherwise be necessary. Data glasses with a particularly individual, i.e.User-specific vision correction can be achieved in a simple way without having to buy separate new data glasses and without uncomfortable and unsightly additional devices for achieving the vision correction.

[0030] The ability to easily replace the lens can also help open up new sales channels for smart glasses. This allows the smart glasses frame, possibly with a lens without vision correction, to be selected and tried on in a store, at an optician, or online. Subsequently, a replacement lens is manufactured based on the user's personal needs, e.g., with customized vision correction, customized eyebox position, UV protection, and / or tint. This replacement lens can be inserted into the smart glasses frame by the user or an optician, or replaced with the previously installed lens.

[0031] Preferably, the display can be connected to the spectacle frame in a positionally variable manner. This means that the display can be moved within narrow limits relative to the spectacle frame. The movement can be enabled laterally, i.e. essentially in the plane of the spectacle frame, and / or essentially perpendicular to the plane of the spectacle frame. For example, a floating mounting of the display relative to the spectacle frame can be implemented. Lateral movement can be enabled, for example, by dimensioning guide elements for connecting the display and spectacle frame with a predeterminable play. This allows the spectacle lens to be changed within certain tolerances without compromising the necessary precise positioning of the display and spectacle lens relative to one another. This enables the spectacle lens to be changed more easily.

[0032] To create a positionally variable connection between the display and the spectacle frame, elastically deformable elements, e.g. in the form of foam elements, can be arranged between the display and the spectacle frame.

[0033] Such elastically deformable elements can be compressed and relaxed, allowing the distance between the display and the spectacle frame to be variable while preventing unwanted movement. The elastically deformable elements can preferably enable movement of the display relative to the spectacle frame substantially perpendicular to the plane of the spectacle frame.

[0034] Depending on the design, the spectacle frame can be made up of several parts.

[0035] For example, the spectacle frame may have a front frame part and a rear frame part complementary to the front frame part.

[0036] This means that the front frame part and the rear frame part complement each other and can be assembled and connected to form the glasses frame using click connections, screw connections or similar.

[0037] The two-part design of the frame allows for easy and safe replacement of the lens by separating the front and rear frame parts and reconnecting them after the lens has been replaced.

[0038] Furthermore, the display can also be positioned between the front and rear frame sections and connected to the glasses frame. For example, the display held in the display holder can be inserted into one of the two frame sections, such as the rear frame section, and screwed to it. This allows for a protected arrangement of the display, preventing damage to the display, for example, if the data glasses are dropped.

[0039] Another possibility for a multi-part design of the spectacle frame can be for the spectacle frame to have an upper frame part and a lower frame part, which can be connected to and detached from one another, for example in the nose area and / or in the temporal area, so that in the above variant with a front and a rear frame part, the spectacle lens and / or the display can be inserted into the spectacle frame or connected to the spectacle frame. In this case, the spectacle lens or the display, if necessary together with the display holder, can be inserted into the spectacle frame with some play and then locked again by connecting the frame parts. While the spectacle lens can be locked in a fixed position, the display can preferably be locked in a variable position, as already described.

[0040] Alternatively, the spectacle frame can be designed as a single piece, for example as a single piece and rigid or as a single piece and flexible.

[0041] In a one-piece rigid design, the spectacle lens can be inserted into the spectacle frame, for example, by placing the spectacle lens on the temporal side of the spectacle frame and then pressing it nasally into the frame with a slight rotation, whereby spectacle lens guide elements arranged on the spectacle lens are inserted into the spectacle frame guide elements during this rotational movement.

[0042] If the frame is constructed as a single piece, the display can be inserted and attached from behind into the frame, optionally in a variable position.

[0043] A one-piece frame design offers the advantage of simpler manufacturing. Furthermore, stability can be increased compared to a multi-piece design, as there are no joints between the frame parts. A one-piece, flexible frame design may allow the frame to be opened and closed again, for example, in the nasal and / or temporal region. With a suitably flexible frame design, it can then be deformed in such a way that the lens and / or display can be inserted into the frame and secured by closing the frame.

[0044] Another aspect of the invention relates to an interchangeable spectacle lens for smart glasses. The spectacle lens comprises a spectacle lens shell, an optical fiber configured to guide a light path for a virtual image, and spectacle lens guide elements configured to position and align the spectacle lens relative to a display of a smart glasses frame.

[0045] The spectacle lens can be combined, in particular, with a smart glasses frame as described above, i.e., the display of a smart glasses frame can be the display of the smart glasses frame explained above. Reference is made to the above explanations in this regard. The advantages of the smart glasses frame are correspondingly linked to the spectacle lens.

[0046] The lens shell can, for example, be a corrective shell, i.e., a lens shell designed to correct a visual defect or to correct vision. Alternatively or additionally, the lens shell can, for example, have UV protection and / or a tint. Other customized designs are also possible, e.g., adjusting the eyebox position to the pupil position of the eye looking through the lens with fiber optic cable, i.e., the lens shell can dictate the position of the eyebox. The pupil position can, for example, be determined based on the interpupillary distance between the right and left eye and / or, for one eye, as the monocular pupil distance to the center of the nosepiece of the frame.

[0047] The lens shell is not limited to a specific geometric shape and can be made of, for example, a plastic material or glass, possibly with one or more coatings. The lens shell can also be constructed from multiple parts.

[0048] The lens shell can have a coupling region for coupling an image generated by the display into the optical fiber. Furthermore, the lens shell can have an output region with an output structure for outputting an image generated by the display and reflected within the optical fiber toward the user's eye when the lens is in use. For this purpose, known input and output structures can be used, for example; the invention is not limited to a specific input or output structure.

[0049] In addition to the lens shell, the lens features an optical waveguide that guides the light path for a virtual image. This means that, when the lens is in use, it guides an image generated by the display to the output coupling structure by means of total internal reflection. The optical waveguide is also referred to as a waveguide.

[0050] In addition, the lens has lens guide elements. These are designed to position and align the lens relative to the display and are therefore particularly complementary to the frame guide elements described above.

[0051] The lens guide elements can be designed, for example, as locating or guiding pins, for example, cylindrical, or as a corresponding counterpart, i.e., as recesses that accommodate locating or guiding pins. A combination of locating or guiding pins and receiving recesses, or a (partial) other design of the lens guide elements, e.g., as ribs or webs, is also possible. The precise geometric design of the guide elements depends on the geometric conditions and the construction of the lens and the data glasses frame into which the lens is to be inserted.

[0052] In order to enable not only positioning the lens but also alignment and, for example, to prevent it from twisting, at least two lens guide elements are provided, which can be combined with each other in any desired way, e.g., in the form of a cylindrical guide pin with a guide rib arranged thereon to ensure a specific alignment of the guide pin in a receiving recess. Preferably, the at least two lens guide elements should be arranged with the greatest possible distance from each other to enable the most precise positioning and alignment of the lens with respect to the display.

[0053] The lens guide elements serve to precisely position and align the lens with respect to the display. This enables simple and non-destructive replacement of the lens, for example by an optician or the user themselves. This makes it possible to obtain data glasses with different lenses, which allow, for example, individual vision correction, adaptation to the individual pupil position, UV protection, tinting, etc. If, for example, a different vision correction is desired, only the lens needs to be replaced, while the display always remains connected to the frame. In other words, the data glasses frame can continue to be used with the display, thus saving costs and material for a new production that would otherwise be necessary. Data glasses with a particularly individual, i.e.User-specific vision correction can be achieved in a simple way without having to buy separate new data glasses and without uncomfortable and unsightly additional devices for achieving the vision correction.

[0054] The customized spectacle lens, for example with vision correction, can be manufactured at a first location. It can then be transported to the location where the spectacle lens is to be inserted into a smart glasses frame, for example, at an optician's or at the user's location. Alternatively, a semi-finished spectacle lens can be manufactured at a first location and then sent to an optician or similar location where the lens is to be replaced or inserted. The optician can then process the semi-finished spectacle lens, e.g., incorporate a customized vision correction, and then replace the lens or insert it into the smart glasses frame. It should be ensured that the spectacle lens guarantees transparency and that the virtual image is displayed correctly.

[0055] The lens shell and lens guide elements can preferably form a single-piece component, i.e., they can be manufactured monolithically, e.g., by injection molding. This enables simple and reproducible production of the lens and can increase the accuracy of the positioning and alignment of the lens relative to the display. Alternatively, the lens guide elements can also be manufactured separately from the lens shell and then connected to the lens shell, with or without an integrated optical fiber.

[0056] Another aspect of the invention relates to data glasses. The data glasses comprise a data glasses frame with a frame configured to hold and position an interchangeable lens, and a display connected to the frame and configured to generate a virtual image. The display can be connected to the frame in a positionally variable manner, e.g., by arranging elastically deformable elements between the display and the frame to form a positionally variable connection.

[0057] Furthermore, the data glasses have an interchangeable lens arranged in the data glasses frame, with a lens shell and an optical fiber configured to guide a light path for the virtual image. The lens shell can preferably be configured to correct a visual defect.

[0058] The smart glasses frame and / or the lens can be designed according to the above description. In this respect, reference is made to these explanations of the smart glasses frame and the lens. The advantages of the smart glasses frame and the lens are correspondingly associated with the smart glasses. The smart glasses are characterized by the interchangeability of the lens(es), so that adaptation to individual needs can be achieved in a simple manner by reusing the smart glasses frame. For example, a non-destructive exchange of lenses with different properties regarding individual vision correction, adjustment of the eyebox position to the individual pupil position, different UV protection and / or different tint can be carried out. Even if a lens is defective, it can be easily replaced non-destructively.

[0059] The interchangeability of the lens is made possible by connecting the display and, if necessary, other optical elements to the data glasses frame, e.g., by attaching them to the frame or hinge. The display can be mounted in a position-free manner, i.e., positionally variable, as required. For example, the lens can be connected to the display only by means of appropriate guide elements, e.g., the frame and lens guide elements described above, or indirectly, e.g., via a display holder.

[0060] Alternatively or in addition to such a guide, the spectacle lens and the display can be connected to one another by means of an easily removable connection, e.g., by means of a so-called peelable adhesive. For example, the adhesive can be designed to be mechanically removable, e.g., by peeling off, physically by dissolving it using a suitable solvent, and / or thermally from the connecting surface. In other words, the spectacle lens can be bonded to the smart glasses frame by means of an adhesive that is non-destructively removable, at least with respect to the smart glasses frame, preferably with respect to the smart glasses frame and the spectacle lens. To remove the adhesive, the smart glasses can, for example, be heated to a suitable temperature.

[0061] Attaching the lens using an easily removable adhesive can enable secure and simple positioning and alignment of the lens relative to the display. Another aspect of the invention relates to a kit of parts for obtaining smart glasses. The kit comprises a smart glasses frame and at least one lens as described above. For a more detailed explanation of the smart glasses frame and the lens, reference is made to the above explanations; the kit combines the advantages of the smart glasses frame and the lens.

[0062] Optionally, the parts kit may include instructions for replacing the lens or for inserting the lens. Such instructions may, for example, include an explanation of the method for assembling data glasses described below.

[0063] Another aspect of the invention relates to a method for assembling smart glasses. The method comprises: providing a smart glasses frame with a frame configured to hold and position an interchangeable lens, and a display connected to the frame, configured to generate a virtual image; providing an interchangeable lens with a lens shell and an optical fiber configured to guide a light path for the virtual image; positioning and aligning the lens and display relative to one another; and securing the lens in the smart glasses frame.

[0064] Using this method, one of the data glasses described above can be mounted. In this respect, reference is made to the above explanations. The advantages of data glasses are associated with this method.

[0065] The lens can be attached to the data glasses frame mechanically and / or using a non-destructively removable adhesive.

[0066] The data glasses frame and the lens can be designed as described above. The alignment and positioning of the lens and display can then be achieved using the lens guide elements and the frame guide elements.

[0067] Further features, properties, and advantages of the present invention are explained in more detail below using exemplary embodiments with reference to the accompanying figures. Figure 1 shows an exploded view of an exemplary data glasses;

[0068] Figure 2 is a schematic representation of an exemplary

[0069] spectacle lens;

[0070] Figure 3 is a schematic representation of an exemplary

[0071] display holder;

[0072] Figure 4 is a schematic representation of an exemplary one-piece data glasses frame;

[0073] Figure 5 is a diagram illustrating the insertion of a spectacle lens into a spectacle frame; and

[0074] Figure 6 shows a flow chart of an exemplary method for assembling data glasses.

[0075] Figure 1 shows a schematic exploded view of data glasses 100 with a data glasses frame 10 and a lens 50. The assembly of such a data glasses 100 is explained in more detail below with reference to Figure 6.

[0076] The data glasses frame 10 has a two-part frame 11 with a front frame part 15 and a rear frame part 16. The front frame part 15 and the rear frame part 16 are complementary to one another and, when assembled, form the frame 11. The frame 11 serves to hold and position the interchangeable lens 50. Figure 1 shows only a single lens 50, which is or will be inserted into the right lens opening 22. Another interchangeable lens (not shown) designed to be mirrored to the lens 50 shown can be or will be inserted into the left lens opening 23. The frame area surrounding the right and left lens openings 22, 23 are connected to one another by means of a nose bridge 25.

[0077] Connected to the eyeglass frame 11 is a display 12 designed to generate a virtual image. The display 12 has a connector for connecting to the ribbon cable 19, which in turn is connected to a battery for power supply (not shown), as well as a flexible circuit board. The display 12 is mounted in a display holder 17, e.g., pushed into corresponding guide elements and / or glued to the display holder 17. The display 12 and the display holder 17 together form a display-display holder element 24.

[0078] The display holder 17 is connected to the display holder mount 18 via click-in connecting elements 20a, 20b (see Figure 4). Alternatively or additionally, further connecting elements can be provided to connect the display holder 17 and the display holder mount 18. Two elastically deformable elements 14a, 14b, e.g., foam or elastomer elements, are arranged between the display holder 17 and the display holder mount 18. The elastically deformable elements 14a, 14b enable a certain movement of the display-display holder element 24 in the forward and backward direction, i.e., when using the data glasses 100, toward the surroundings and toward the user's face.

[0079] The display holder mount 18 has two positioning pins (not shown) that are inserted into designated recesses (not shown) in the rear frame part 16. The display holder mount 18 can be secured to the rear frame part 16 via an additional screw connection (screw 21).

[0080] In addition to the data glasses frame 10, the data glasses 100 have the replaceable lens 50. The lens 50 is a monolithic data glasses lens element comprising a lens shell 51 and an optical fiber 52.

[0081] The lens shell 51 can optionally be designed with prescription correction and / or include UV protection. Alternatively or additionally, the lens shell 51 can be tinted. Further customizations, e.g., adaptation to the individual pupil position of the eye looking through the lens 50 with optical fiber 52, are possible. Furthermore, the lens shell 51 comprises a coupling region and / or a coupling structure (not shown separately) for coupling the image generated by the display 12 into the optical fiber 52, and an output structure (not shown separately) for outputting the image generated by the display 12 from the optical fiber 52 toward the user's eye. The optical fiber 52 guides the light path of the virtual image from the display 12 to the output structure of the lens shell 51.Optionally, the coupling and / or the decoupling structure can be formed as separate elements from the spectacle lens shell 51 or as part of the optical waveguide 52.

[0082] As shown in Figure 2, the spectacle lens 50 has two spectacle lens guide elements 53a, 53b, which in the exemplary embodiment are designed as guide cylinders. However, the invention is not limited to a specific embodiment of the spectacle lens guide elements 53a, 53b and the spectacle frame guide elements 13a, 13b described below. The spectacle lens guide elements 53a, 53b are located laterally on the spectacle lens 50 in the area in which the optical fiber 52 is connected or arranged to the display holder 17. The spectacle lens shell 51 and the spectacle lens guide elements 53a, 53b form a one-piece component and can be manufactured together, for example, by injection molding.

[0083] The spectacle lens guide elements 53a, 53b serve to position and align the spectacle lens 50 with respect to the display 12. For this purpose, the spectacle lens guide elements 53a, 53b engage in spectacle frame guide elements 13a, 13b of the data glasses frame 10.

[0084] In the exemplary embodiment, the spectacle frame guide elements 13a, 13b are designed in the form of recesses and, as shown in Figure 3, are arranged on the display holder 17. Furthermore, the recesses of the spectacle frame guide elements 13a, 13b are widened in a funnel shape, i.e., they have an enlarged diameter in the front area. This enables easy insertion of the spectacle lens guide elements 53a, 53b, since precise positioning of the spectacle frame guide elements 13a, 13b and the spectacle lens guide elements 53a, 53b is not necessary. The tolerance range during assembly or replacement of the spectacle lens 50 is thereby increased, so that this process can also be performed by less specialized personnel and, if necessary, even by the user themselves.

[0085] The spectacle frame guide elements 13a, 13b, together with the spectacle lens guide elements 53a, 53b, ensure a secure and precise positioning and alignment of the display 12 and the spectacle lens 50 to one another, so that the virtual image generated by the display 12 can be reliably perceived in the eyebox.

[0086] At the same time, replacement of the spectacle lens 50 is possible, since it is not firmly connected to the display 12, but the spectacle frame guide elements 13a, 13b and the

[0087] Lens guide elements 53a, 53b can be detached from each other non-destructively if necessary. For example, a first lens 50 without vision correction can be exchanged for a second lens 50 with vision correction.

[0088] In the assembled data glasses 100, the spectacle lens 50 is inserted into the rear frame part 16, with the spectacle frame guide elements 13a, 13b and the spectacle lens guide elements 53a, 53b engaging with each other. The spectacle frame guide elements 13a, 13b and the

[0089] Lens guide elements 53a, 53b are designed to ensure precise positioning. Due to the connection between the rear frame part 16 and the front frame part 15, the lens 50 is pressed against the display / display holder element 24. The display / display holder element 24 is, in turn, pressed against the display holder mount 18, thereby holding the lens 50 in position.

[0090] The connection of the front and rear frame parts 15, 16 can be realized by hooks arranged on the two frame parts 15, 16, which hook into grooves arranged on the lower edge of the spectacle lens 50 (not shown). In addition, screw connections can be provided in the upper region of the spectacle frame 11 (not shown). Alternative, repeatedly detachable connection options for the front and rear frame parts 15, 16 are of course possible. To replace or install the spectacle lens 50, the front and rear frame elements 15, 16 are separated from one another. The spectacle lens 50 can then be removed and replaced with another spectacle lens 50, or a new spectacle lens 50 can be inserted. After the spectacle lens 50 has been replaced or inserted, the two frame parts 15, 16 are reconnected.This process requires no special tools, and optical inspection is also unnecessary. Therefore, these steps can also be performed by personnel not specialized in smart glasses, such as an optician or, if necessary, the user themselves.

[0091] Figure 4 shows a further exemplary data glasses frame 10 with a one-piece glasses frame 11 and two associated glasses lenses 50. Also shown are two glasses temples 29 which are connected to the glasses frame 11 by means of hinges 28. The replacement or installation of the glasses lenses 50 can essentially take place as described above with reference to Figures 1 to 3. The lower frame part 26 and the upper frame part 27 can, as shown in Figure 4, be detached from one another in the region of the nose bridge 25. Alternatively or additionally, detachment in the temporal region, i.e. on the outer sides of the glasses frame 11, would also be possible. After opening the glasses frame, existing glasses lenses 50 can be removed. Subsequently, spectacle lenses 50 can be inserted into the opened spectacle frame 11, possibly with play, whereby the spectacle lens guide elements 53a, 53b engage in the spectacle frame guide elements 13a, 13b.The lenses 50 are then locked in position by connecting the upper and lower frame parts 26, 27.

[0092] Figure 5 shows another exemplary data glasses frame 10 with a one-piece glasses frame 11 and an associated spectacle lens 50. In contrast to the one-piece glasses frame 11 according to Figure 4, the glasses frame according to Figure 5 is not divisible. The display / display holder element 24, together with the display holder mount 18, is inserted into the glasses frame 11 from behind and is preferably fastened in a variable position, e.g., screwed or glued at one point and plugged onto guide elements, e.g., guide pins, of the glasses frame 11 at at least one other point. The glasses lens 50 is placed on the temporal side from behind the glasses frame 11 and then pressed nasally into the glasses frame 11 with a slight rotation. During this rotating movement, the glasses lens guide elements 53a, 53b are inserted into the glasses frame guide elements 13a, 13b.

[0093] Figure 6 shows an exemplary flow chart of a method 200 for assembling data glasses 100. The data glasses 100 can, for example, be one of the data glasses 100 explained above with reference to Figures 1 to 5.

[0094] After starting the method, the data glasses frame 10 with glasses frame 11 and display 12 connected to the glasses frame 11 (step S1) as well as a replaceable spectacle lens 50 with spectacle lens shell 51 and optical fiber 52 (step S2) are provided.

[0095] In step S3, the spectacle lens 50 and the display 12 are positioned and aligned relative to each other. For this purpose, the spectacle lens guide elements 53a, 53b and the spectacle frame guide elements 13a, 13b can be positioned and aligned relative to each other. In step S4, the spectacle lens is secured in the data glasses frame 10.

[0096] The overall assembly process of the data glasses 100 shown in Figure 1 can, for example, be described as follows:

[0097] The display 12 is mounted on the display holder 17.

[0098] The display holder 17 is connected to the display holder support 18 via click-connecting elements 20a, 20b. Elastically deformable elements 14a, 14b are inserted between the display holder 17 and the display holder support 18.

[0099] The display 12 with display holder 17 and display holder mount 18 is inserted into the rear frame part 15 of the spectacle frame 11 and secured by means of screw 21. The display / display holder element 24 is mounted in a floating manner as described above. The spectacle lens 50 is inserted into the rear frame part 15. Simultaneously, the spectacle lens 50 and the display / display holder element 24 are guided via the spectacle frame guide elements 13a, 13b arranged on the display holder 17 and the

[0100] Spectacle lens guide elements 53a, 53b are connected to each other.

[0101] - The front and rear frame parts 15, 16 are joined together.

[0102] - By joining the two frame parts 15, 16, the spectacle lens 50 is pressed against the display-holder element 24. The display-holder element 24 is in turn pressed against the display holder mount 18, thereby holding the spectacle lens 50 in position. The front and rear frame parts 15, 16 are connected by hooks arranged on the two frame parts 15, 16, which are hooked into grooves arranged on the lower edge of the spectacle lens 50. In addition, a screw connection is provided in the upper area of ​​the spectacle frame 11.

[0103] The described assembly process can be modified depending on the specific circumstances. For example, the specified process steps may be performed in a different order, or additional process steps may be added. Further deviations may arise for assembly-related reasons, e.g., if the exact connecting, joining, and / or guiding elements are designed differently.

[0104] The figures are not necessarily detailed or to scale and may be enlarged or reduced to provide a better overview. Therefore, functional details disclosed herein are not to be understood as limiting, but merely as an illustrative basis for providing guidance to those skilled in the art for variously employing the present invention. In the figures, identical or similar elements are designated by identical reference numerals where appropriate.

[0105] The term "and / or" as used here, when used in a series of two or more elements, means that any of the listed elements can be used on its own, or any combination of two or more of the listed elements can be used. For example, the term "UV protection and / or tint" includes UV protection alone, tint alone, or UV protection and tint in combination. Directional terminology, such as "back," "from," "below," and "above," refers to the orientation of smart glasses when used as intended, i.e., when worn by the user. "Back" therefore means toward the user's face, "front" means toward the environment, i.e., opposite the user's face, "below" means toward the ground, and "above" means toward the sky.

[0106] Unless otherwise stated, connections can be made in different ways, e.g. as clip, adhesive or screw connections.
