- Such conventional, production-related and/or environmentally-related deviations can in particular comprise relative deviations of a maximum of approximately 20%, preferably a maximum of approximately 10%, more preferably a maximum of approximately 5%.
- conventional, production-related and/or environmentally-related deviations can comprise absolute deviations, for example of a maximum of approximately 2 mm, preferably of a maximum of approximately 1 mm, more preferably of a maximum of approximately 0.1 mm, and/or for example of a maximum of approximately 2°, preferably of a maximum of approximately 1°, more preferably of a maximum of approximately 0.1°.
- the method for producing the customized output spectacle frame is in particular not limited to a specific method of producing the customized output spectacle frame. Rather, it is known to the person skilled in the art that a variety of manufacturing methods can be used to produce spectacle frames, and thus also for the customized output spectacle frame, e.g. casting methods, injection molding methods, 3D printing methods and/or cutting methods.
- this makes it possible to refrain from further adjustment of the adjusted spectacle frame, for example when the spectacle frame is handed over to the wearer, since it already essentially has the second shape.
- the wearer can thus be given an already completely individualized and/or biometrically adjusted spectacle frame. This can be used to avoid differences in the adjustment of the spectacle frame between an original, first adjustment and a final adjustment. This also enables further reorders of additional adjusted spectacle frames without the need for further adjustments, e.g. by an optician.
- the method for producing the customized output spectacle frame further comprises determining centering data for the customized physical model spectacle frame for the spectacle wearer.
- the centering data can comprise at least an eye distance, a deflection angle, a viewing height, a pupil distance (see DIN EN ISO 13666:2019-12, section 3.2.28), a corneal vertex distance (see DIN EN ISO 13666:2019-12, section 3.2.40), a frame lens angle (see DIN EN ISO 8624:2020-11, section 3.2.13), a forward inclination of the customized physical model spectacle frame (see DIN EN ISO 13666:2019-12, section 3.2.37) and/or an eye rotation point.
- the centering data can be determined or measured using a centering data measuring device.

- a An example of calculating the lenses taking the centering data into account is described in Dipl.-Ing. (FH) Georg Esser, PD Dr. Dietmar Uttenweiler: “The performance of individual progressive lenses”, DOZ 12/2005, page 38.
- the production of the lenses can also include, for example, manufacturing the lenses and/or edging the lenses.
- the method for producing the customized output spectacle frame further comprises inserting the spectacle lenses into the customized output spectacle frame.
- the method for producing the customized output spectacle frame after inserting the spectacle lenses can comprise adjusting the customized spectacle frame with inserted spectacle lenses in such a way that the customized spectacle frame essentially has the second shape after inserting the spectacle lenses.
- the method is not limited to this. Rather, the spectacle lenses can also be inserted into an output spectacle frame blank (as described below, for example). In particular, the spectacle lenses can be inserted into the output spectacle frame blank before and/or after a shape of the output spectacle frame blank has been adapted, taking the adaptation parameters into account.
- differences between the adapted physical model spectacle frame and the adapted output spectacle frame can have a significant undesirable influence on the corrective effect of the individualized spectacles, since centering data for the adapted physical model spectacle frame are also included in the calculation of the spectacle lenses.
- centering data can differ from one another due to these differences between the adapted physical model spectacle frame and the adapted output spectacle frame, which has an influence on the correspondingly calculated spectacle lenses.
- the method for producing the adapted output spectacle frame includes, for example, producing the adapted output spectacle frame taking into account the determined adaptation parameters in such a way that the adapted output spectacle frame has the second shape within further tolerances or taking the further tolerances into account.
- the other tolerances can include, for example, quality tolerances.
- Quality tolerances can be understood as tolerances that influence the optical quality of the corrective effect, for example due to changes in corneal vertex distances.
- the quality tolerances can be dependent in particular on the corrective effect of the glasses, in the same way that errors in determining the centering data affect the optical quality of the corrective effect. For example, an error in adjusting the temple length to the bow (e.g. 1 mm too long) during the manufacture of the adjusted output glasses frame can have a direct effect on the fit of the adjusted output glasses frame on the nose, which can change the corneal vertex distance by a similar amount and the adjusted output glasses frame can also slide down slightly along the nose of the wearer.
- an error in adjusting the frame lens angle, the bridge width and/or the inclination angle can affect a pupil distance and/or a forward inclination.
- the Quality tolerances can be selected in such a way as to define a maximum acceptable deviation from the second form.
- individual refraction data of the respective spectacle wearer can also be taken into account when defining the quality tolerances. For example, a corneal vertex distance of around 13mm, a pupil distance of around 64mm, a forward inclination of around 9 degrees and/or a frame lens angle of around 5 degrees can be used as a reference value for the quality tolerances.
- the further tolerances can also include determination tolerances for determining the centering data.
- the determination tolerances can be taken into account when determining the centering data.
- the determination tolerances can be selected in particular to define a maximum acceptable inaccuracy or a maximum acceptable measurement error or determination error when determining the centering data.

- the determination tolerances can include inclination angle tolerances, wherein the inclination angle can be determined, for example, with an accuracy or inclination angle tolerance of approximately or approximately 1°, for example using a template or a template element or an inclination angle template element.
- the determination tolerances can include bracket length to bow tolerances, whereby the bracket length to bow can be determined with an accuracy or bracket length to bow tolerance of approximately 1 mm.
- the quality tolerances and the determination tolerances a particularly good overall optical performance of the adjusted output spectacle frame or of the spectacles handed over to the customer can be achieved, since the overall optical performance can be particularly dependent on at least both a quality of the centering data determination and a quality of the adjusted output spectacle frame.
- the additional tolerances can include, for example, tolerances specific to the wearer of glasses.
- tolerances specific to the wearer of glasses can be understood as tolerances beyond which the wearer of glasses no longer perceives the adjusted output glasses frame as being equivalent to the adjusted physical model glasses frame and could, for example, request a different, more precise adjustment from the optician (for example, because the adjusted output glasses frame is uncomfortable on the nose for the wearer of glasses and/or causes pressure points due to an incorrectly transferred adjusted temple length to the nose).
- the additional tolerances can specify one or more corresponding tolerance intervals for each of the determined adjustment parameters.
- one or more quality tolerances, one or more determination tolerances and/or one or more wearer-specific tolerances can also be specified.
- an incorrect frame lens angle can not only have a direct effect on the optical correction effect, but can also cause a different offset from the nose pad to the front temple ends, for example by affecting the length of the temples.
- the method for producing the adapted output spectacle frame further comprises determining individual, in particular objective and/or subjective, refraction data of the spectacle wearer, wherein the individual refraction data are also taken into account when producing the spectacle lenses.

- the individual refraction data can be determined or measured using a refraction data measuring device.
- a refraction data measuring device which allows a particularly efficient and precise determination of the individual refraction data is the Rodenstock DNEye® scanner.
- the method for producing the customized output spectacle frame further comprises determining individual parameters of the spectacle wearer, wherein the determined individual parameters are also taken into account when producing the spectacle lenses.
- the individual parameters of the spectacle wearer can, for example, comprise one or more of the following parameters: pupil distance, corneal vertex distance, centering height, forward inclination and/or frame lens angle.
- the individual refraction data, the centering data, the adjustment parameters and/or the individual parameters can be stored digitally and thus be reusable, e.g. for reordering additional adjusted spectacle frames.
- the production of the adapted output spectacle frame comprises 3D printing the adapted output spectacle frame taking into account the determined adaptation parameters.
- the 3D printing can be designed to produce the adapted output spectacle frame taking into account the determined adaptation parameters, so that the 3D-printed, adapted output spectacle frame essentially has the second shape. This makes it possible in particular to take the adaptation parameters into account when producing the adapted output spectacle frame, which can eliminate the need for subsequent adaptation.
- the use of 3D printing enables the adapted output spectacle frame to be produced at essentially any location, provided that a 3D printing device is available. Furthermore, this can also make it possible to produce the adapted output spectacle frame essentially immediately after the adaptation parameters have been determined.
- the desired customized spectacle frame could be produced on site, e.g. at the optician's and/or during the first visit to the optician.
- the production of the customized output spectacle frame can include milling the customized output spectacle frame from a material blank, e.g. from wood, taking into account the determined adaptation parameters.

This makes it particularly easy to take into account the adjustment parameters when producing the adjusted output spectacle frame, since these already represent at least a spatial difference between the first form and the second form.
- the output spectacle frame blank may have a third shape, wherein the third shape is substantially different from the first shape, wherein in particular the third shape and the first shape have substantially the same geometry.
- the output spectacle frame blank and the physical model spectacle frame may differ from each other, while having substantially the same geometry.
- Two spectacle frames can have the same geometry if the contact points of the respective spectacle frames with the head of the wearer are the same and/or the weight and/or weight distribution of the respective spectacle frames differ insignificantly.
- two spectacle frames can have essentially the same geometry, but differ from one another, for example in their color and/or in their plastic ornamentation and/or in their respective lens shapes.
- two spectacle frames could have essentially the same geometry, but differ from one another, for example in their material properties.
- the physical model spectacle frame could consist of an inferior and/or bendable material, e.g. a metal alloy, while the output spectacle frame blank consists of a higher-quality and/or more robust or rigid material, e.g. a gold and/or platinum alloy.
- the physical model spectacle frame could have inferior ornamentation and/or decorative stones, while the output spectacle frame blank has higher-quality ornamentation and/or decorative stones or gemstones. This enables, for example, simplified adaptation of the physical model spectacle frame.

- the method comprises producing the adapted output spectacle frame taking into account the determined adaptation parameters such that that the customized output eyeglass frame substantially has the second shape, wherein the customized output eyeglass frame has substantially the same geometry as the customized physical model eyeglass frame.
- this makes it possible for the physical model spectacle frame to at least not completely match a model spectacle frame desired by the spectacle wearer.
- This makes it possible to minimize the number or range of model spectacle frames from which the spectacle wearer can select a desired model spectacle frame.
- this makes it possible to group spectacle frames, e.g. a range of an optician and/or frame manufacturer, into adjustment categories. At least one spectacle frame can be assigned to each adjustment category and/or each spectacle frame can be assigned to at least one adjustment category. All spectacle frames assigned to a respective adjustment category can in particular have essentially the same geometry.
- the determined adjustment parameters can also be transferred or applied to output spectacle frames and/or output spectacle frame blanks which, while having essentially the same geometry, differ in shape from the physical model spectacle frame or from the first shape.
- a large number of differently shaped output spectacle frames and/or output spectacle frame blanks can be adjusted taking into account the same determined adjustment parameters.
- a respective physical model spectacle frame can be provided for each adjustment category, which enables the optician, for example, to offer a large selection of adjusted output spectacle frames without having a separate spectacle frame available for each spectacle frame model for determining the adjustment parameters, since the adjustment parameters can be transferred to each model from an adjustment category.
