Description

[Technical Field]

[0001] The present invention relates to the field of eyewear, and more particularly to the field of personalized eyewear. [Background technology]

[0002] It is known that users select their preferred eyewear from an existing eyewear catalog.

[0003] It is also known to adapt existing eyewear, for example using additive manufacturing, to change the eyewear according to the morphology of a person's face.

[0004] It is also known to use additive manufacturing to build eyewear from scratch.

[0005] However, once a user selects eyewear to suit their preferences, the selected eyewear may not be specifically suited for a particular activity that was not intended for the selected eyewear at the time of its conception. Similarly, the user may not be able to incorporate certain features into the selected eyewear.

[0006] Therefore, a need exists to provide a way to modify existing eyewear so that it becomes compatible with particular activities or functions for which it was not originally specifically adapted.

[0007] Particular functions or activities may include outdoor and sun activities, sporting activities, and the like.

[0008] To this end, the present invention allows for the generation of modified manufacturing data for eyeglass frames based on existing eyeglass frames and target specific activities or functions. Summary of the Invention [Means for solving the problem]

[0009] Therefore, the object of the present invention is to a. providing a plurality of eyeglass frames; b. selecting a frame from a plurality of eyeglass frames; c. determining data associated with the selected frame; d. Modifying the determined data while respecting at least one predetermined concept rule to obtain modified data; e. calculating the modified data obtained by the modification to generate modified manufacturing data for the eyeglass frame; The present invention provides a method for generating manufacturing data for modified eyeglass frames, comprising:

[0010] Manufacturing data refers to all data necessary to manufacture a modified eyeglass frame. Manufacturing data may include or be derived from pantoscopic angles, face form angles, base curves, temple shapes, wrap angles, etc.

[0011] In certain embodiments, methods according to the present disclosure provide fully or partially customized eyeglass frames to human individuals in a fully automated manner.

[0012] In particular, steps (d) and (e), and in one embodiment step (c), are modified and calculated fully automated, and thus in one embodiment, determinations are made using at least one processor to generate modified manufacturing data for the eyeglass frames based on the predetermined concept rules.

[0013] The steps of providing and selecting allow for the provision of existing eyeglass frames. The existing eyeglass frames may be eyeglass frames that are already in use and have corresponding lenses designed to correct vision. In this case, the plurality of eyeglass frames from which one selected frame is selected corresponds to the plurality of existing eyeglass frames from which the user selected the eyeglass frame he or she wishes to change.

[0014] Alternatively, the existing eyeglass frames may be new eyeglass frames selected from among a number of eyeglass frames, for example at an eyeglass store or in a catalogue. In that case, at the time of selection, the eyeglass frames may be fitted with mere demonstration lenses that are not designed to correct the wearer's vision. In the case of a catalogue selection, wearing the eyeglasses may not even be important at the time step b is performed.

[0015] The data determined in the determining step (step c) and modified in the modifying step (step d) may include any data related to the aspects or features of the eyeglass frame, such as pantoscopic angle, face form angle, base curve, temple shape, wrap angle, etc.

[0016] At least one concept rule of the modification step is intended to maintain the aesthetics or spirit of the existing eyeglass frame while keeping the modification possible. For example, it may be important to modify several parameters together to respect certain proportions, or to ensure that some angles remain below a certain threshold so that the eyeglass frame can stand on the nose, etc.

[0017] The concept rules will depend on the specific activity and / or function of the target.

[0018] For example, sports or outdoor / sun activity parameters can be changed to increase face coverage and improve sun protection (UV, glare...), the pantoscopic angle, face form angle, base curve, Z thickness can be changed to fit the face shape to limit light entering the eye from the top, bottom or sides, and the temple shape can be changed to reduce the amount of light entering from the sides.

[0019] Similarly, for driving activities, the base curve, pantoscopic angle, and wrap angle can be modified to increase the wearer's field of view and limit back reflections from car headlights at night, and the temple thickness can be reduced to increase peripheral visibility.

[0020] In the case of electrochromic lenses, or more generally eyewear that integrates electronic components, the temples can be modified to include slots that would accommodate electronic boards, batteries, wiring, etc. The face of the eyewear can also be modified to include wiring, sensors, etc.

[0021] The concept rule for step d may include keeping the front 2D projection of the selected frame unchanged.

[0022] In fact, the 2D projection of the selected frame corresponds to the image seen by someone standing in front of the wearer, so keeping this 2D projection the same maintains the spirit and identity of the eyeglass frame.

[0023] Finally, a calculation step (step e) involves calculating these modified data so that they can actually be used as input by the eyeglass frame manufacturer.

[0024] The method according to the invention may further comprise a step c1 consisting of providing a target class of target activity or frame for which the modified spectacle frame is intended, or selecting from a plurality of activity or frame classes.

[0025] Depending on the goal class of a given activity or frame, different concept rules can be selected.

[0026] Preferably, the activities for which the modified eyeglass frames are intended are selected from among sporting activities, activities in the sun, and driving.

[0027] The concept rules for the varying step may also include holding constant eyewear features selected from among temple size, size of connection to temple, nose bridge size, and nose shape.

[0028] These features are unique to some wearers and, if altered, may prevent the wearer from wearing the eyeglass frames.

[0029] The concept rules for the modification step may also include holding constant selected frame features, chosen from color, transparency, opacity, pattern, and decorative features, which may allow the spirit and identity of the modified eyeglass frames to be maintained.

[0030] The concept rules for the modification step may also include adapting the eyeglass frame to the 3D measurements of the wearer's head.

[0031] Such a fitting makes it possible to personalize the eyeglass frames as much as possible for the wearer and to offer the best possible wearing experience.

[0032] The concept rules for the modifying step may also include modifying data selected from among the pantoscopic angle, base curve, wrap angle, front surface thickness, and temple thickness.

[0033] The concept rules for the modifying step may also include modifying selected data from among the pantoscopic angle, base curve, wrap angle, front thickness, and temple thickness while keeping the projected view of the front surface of the eyeglass frame fairly constant.

[0034] These data, as discussed above, can have a very dramatic impact on the possible uses of eyeglass frames.

[0035] At least one of the eyeglass frames provided from among the plurality of eyeglass frames in step a may be a digital frame.

[0036] Using a digital frame as a starting point allows for material savings, which can be particularly important in the case of expensive eyeglass frames.

[0037] At least one of the eyeglass frames provided from the plurality of eyeglass frames in step a may be a physical frame.

[0038] The use of physical frames may allow for a more accurate and reliable selection for the wearer and may allow for the wearer to actually try on the eyeglass frames.

[0039] At least one of the eyeglass frames provided from the plurality of eyeglass frames in step a may be an image of the frame.

[0040] Such photographs can be user-provided or can come from any source, such as a magazine or a movie.

[0041] The plurality of eyeglass frames in the providing step (step a) can, of course, include any combination of digital frames, physical frames, and images of frames.

[0042] Preferably, the manufacturing data for the modified eyeglass frame allows the modified eyeglass frame to integrate complex electronic components.

[0043] The invention can be better understood on reading the following detailed examples, which constitute non-limiting embodiments of the invention, and on examining the accompanying drawings, in which: [Brief explanation of the drawings]

[0044] [Figure 1] FIG. 10 is a curvature diagram of the outer frame shape of half. [Figure 2] Figure 1 shows three different sizes of the same frame design. [Figure 3]Four views of the classic and sport frames are shown. [Figure 4] Shows early eyewear for clear lenses. [Figure 5] 5 shows the eyewear of FIG. 4 modified to improve its protective light properties for outdoor sun activities. [Figure 6] 1 is a summary of an example of a process according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0045] A processor within the terms of this disclosure may include dedicated hardware as well as hardware capable of executing software in association with appropriate software. It may consist of a single dedicated processor, a single shared processor, or multiple individual processors, some of which may be shared. Furthermore, the explicit use of the term "processor" should not be construed to refer exclusively to hardware capable of executing software, but rather refers in a general manner to a processing device, which may include, for example, a computer, a microprocessor, an integrated circuit, or a programmable logic device (PLD). Additionally, instructions and / or data enabling the execution of the relevant and / or resulting functions may be stored on any processor-readable medium, such as, for example, an integrated circuit, a hard disk, an optical disk such as a CD (compact disc) or a DVD (digital versatile disc), a RAM (random access memory), or a ROM (read-only memory). The instructions may be recorded in particular hardware, software, firmware, or any combination thereof.

[0046] A computer-implemented method according to the present disclosure is for providing eyeglass frames.

[0047] In certain embodiments, methods according to the present disclosure provide fully or partially customized eyeglass frames to human individuals in a fully automated manner.

[0048] In the context of this example, a method is provided, comprising: 1) The user selects existing eyewear (either physical eyewear, digital eyewear, or an image of eyewear). The selection is based on design or aesthetic criteria. The selection process can be done via a physical try-on or a virtual try-on, for example, using augmented reality technology. The selection can be based on the shape, size, color or pattern of the eyewear, decoration, material characteristics, brand, etc. 2) The user is then asked to provide an activity for which the eyewear is intended, or an activity they will use the glasses for, or an additional function not provided by the initial eyewear. The activity may be one of various sports activities, outdoor and sun activities, driving activities, etc. The wearer may provide a coefficient to weight each provided activity based, for example, on the time spent on the activity or the importance of the activity. An additional function may be the inclusion of smart components in the eyewear, such as electrochromic lenses or electronic components. 3) The existing eyewear is then modified according to the selected activity / additional features, but the design of the eyewear remains the same. The global design of the face is maintained.

[0049] For example, the 2D frame design, i.e., the front projection view, remains the same during the modification, and / or some specific eyewear features remain constant. Some locations on the eyewear have a specific slope or curvature, or a change in curvature that can be maintained. The size of the temple connection, the size of the nose bridge, and the nose shape remain constant, ensuring wearer comfort similar to the original eyewear.

[0050] To maintain the global design of the surface, there is a need for a set of locations within the eyewear where changes in slope or curvature must be maintained relative to the inner or outer frame shape.

[0051] Figure 1 shows the curvature diagram of half the outer frame shape. This design fingerprint can be used to resize the frame while retaining the design.

[0052] Figure 2 shows three different sizes of the same frame design.

[0053] Preferably, but optionally, decorative features such as color, transparency / opacity, pattern, metal or inserts are kept the same.

[0054] Other parameters are then changed to conform to the desired activity or additional functionality.

[0055] For example, for sporting activities, the size of the temple connections and the size of the endpoints can be increased to improve robustness.

[0056] The geometry of the temples can also be modified to improve stability for sports activities, as shown in Figure 3. Figure 3 includes four views of a classic frame corresponding to the existing frame to be modified, and a sports frame corresponding to the target frame after the data has been modified based on the concept rules.

[0057] Alternatively, several different modifications can be made to improve the sun protection characteristics for outdoor sun activities. Clear eyewear would then be transformed into sun eyewear. However, these modifications are related to the lenses, and additional modifications related to the frame may not be required. Early eyewear for clear lenses typically has a low base curve, a low wrap angle, and limited face coverage, as shown in Figure 4.

[0058] As shown in FIG. 5, the modified eyeglass frame can have a modified wrap angle, a modified pantoscopic angle, and a modified base curve to provide more facial coverage.

[0059] The global process is summarized in Figure 6. Existing eyewear is first selected by the wearer (top row box). Optionally, a three-dimensional head measurement is taken on the wearer (second row right box). Previously introduced activity profiles or unavailable features are provided by the wearer (second row middle box).

[0060] Based on the aforementioned inputs, eyewear modification data is provided to maintain a similar design while providing the desired functionality (third row box).

[0061] Based on this data, it is then possible to manufacture the modified eyewear, which can be done using additive manufacturing, or 3D printing.

[0062] Preferably, the method according to the invention is computer-implemented, i.e. a computer program product comprising one or more instruction sequences accessible to a processor, which may be at least one of the above-mentioned processors, which, when executed by the processor, cause the processor to perform the steps of the method for providing eyeglass frames as described above.

[0063] The method according to the present disclosure may be implemented in a calculation engine, i.e., said at least one processor comprises software and / or hardware that enables whatever change requested by the user in any item or in any location or region or area of ​​the frame to automatically perform an instantaneous recalculation of all parameters and variables of the frame, including parameters that were not requested by the user but that have changed as a result of the change requested by the user.

[0064] It is understood that the described embodiments are not limiting and that the invention can be improved without departing from its framework.

[0065] Unless otherwise specified, the word "or" is equivalent to "and / or." Similarly, the word "1" is equivalent to "at least one" unless specified to the contrary. Unless otherwise specified, all percentages are by weight.
