[0003] The photochromic tint can depend not only on the corresponding radiation but also on other factors, such as ambient and / or lens humidity, air pressure, and especially temperature. This can lead, for example, to a situation where photochromic glasses that function as desired in a southern country with higher (maximum or average) temperatures tint too intensely in a northern country with lower (minimum or average) temperatures, even with insufficient radiation or too early. Conversely, photochromic glasses optimized for colder climates may react too weakly or too late in warmer climates. Similarly, photochromic glasses that function as desired in an average city may behave differently in the mountains with correspondingly lower air pressures and / or at sea with correspondingly higher air or lens humidity.did not react as desired.

The dependent claims relate to advantageous embodiments.

[0006] According to one embodiment of the present invention, two or more optical lenses are configured and / or provided for configuring and / or providing photochromic optical lenses, each of which - a photochromic support, preferably a substrate or a base body, and - have at least one coating which at least partially absorbs and / or reflects radiation which can excite photochromism of the substrate and which, for the sake of a more compact presentation without limiting generality, is also referred to as an attenuation coating.

[0008] According to one embodiment of the present invention, in a further development, another or more other lenses (to be configured or provided), which are preferably identical to each other overall or particularly preferably at least with regard to the photochromic substrates and corresponding (attenuating) coatings and / or different from the first lens(es), in one embodiment of the other lenses to be configured or provided, and are therefore, without limitation of generality, referred to as the second lens(es), - based on or depending on a second parameter dependency specified for these lens(es), different from the aforementioned first parameter dependency, preferably a second desired or target parameter dependency, of a photochromic tint (of the respective lens) (each) - a carrier who - a second photochromic characteristic, different from the first photochromic characteristic mentioned above, or - the first photochromic characteristic is also particularly preferred features, with - a (second) (weakening) coating, the one radiation, by which photochromism of this substrate can be stimulated, with a second attenuation characteristic, different from the first attenuation characteristic mentioned above. at least partially absorbed and / or reflected, combined.

[0009] In one embodiment, in a further development, one or more additional lenses (to be configured or provided) are / are, which are preferably identical overall or particularly preferably at least with regard to the photochromic substrates and corresponding (attenuating) coatings and / or differ from the first and second lens(es), in one embodiment from the other lens(es) to be configured or provided, and are therefore designated as the third lens(es) without limitation of generality. - based on or depending on a third parameter dependency specified for this lens(es), different from the aforementioned first and second parameter dependencies, preferably a third desired or target parameter dependency, of a photochromic tint (of the respective lens) (each) - a carrier who - a third photochromic characteristic, different from the first and second photochromic characteristics mentioned above, or - preferably also exhibits the second photochromic characteristic or especially preferably also exhibits the first photochromic characteristic, with - a (third) (weakening) coating, the one radiation, by which photochromism of this substrate can be stimulated, with a third attenuation characteristic, different from the aforementioned first and second characteristics, Attenuation characteristic at least partially absorbed and / or reflected, combined.

[0010] Similarly, in one version, one or more additional lenses can be configured and / or provided, in particular one or more fourth lens(es) based on or for a fourth parameter dependency, in a further training, one or more fifth lens(es) based on or for a fifth parameter dependency, etc.

[0011] In one embodiment, the first, second, and optionally third, fourth, and optionally fifth parameter dependencies denote or describe different dependencies on the same (one- or multi-dimensional) parameter, in particular different photochromic tints at or for the same parameter value. The parameter may, in particular, comprise one or more one- or multi-dimensional parameters of the lens itself and / or one or more one- or multi-dimensional environmental parameters, and may, for example, include ambient and / or lens humidity, air pressure, or the like, and particularly preferably ambient and / or lens temperature, and in particular specify these.

[0012] One embodiment of the present invention is based on the idea of ​​providing different parameter dependencies of a photochromic tint of lenses for different parameter values, for example, different temperatures, in particular different locations of use with different (application or environmental) parameters or temperatures, and of realizing such different, in particular desired, parameter dependencies of a photochromic tint of lenses wholly or partially by means of different (attenuation) coatings, by which radiation, by which a photochromism of the, preferably structurally identical, substrates, which preferably have the same photochromic characteristics, can be excited, is absorbed and / or reflected with different attenuation characteristics, preferably to different degrees.

[0013] In an advantageous embodiment, this can improve manufacturing, logistics, and / or warehousing, particularly through the use of substrates exhibiting the same photochromic characteristics. Additionally or alternatively, this can advantageously allow for different parameter dependencies of a photochromic tint in lenses, especially (also) through the use of substrates exhibiting different photochromic characteristics.

[0014] Configuration, in one execution, includes planning and / or ordering and / or requesting and / or actual or physical production; in particular, it can be planning, ordering, requesting, and / or actual or physical production. Provisioning, in one execution, includes physical making available, in particular physical production, and / or physical or planned retrieval from a warehouse and / or physical transport, in particular transport to or from a warehouse or delivery; in particular, it can be physical making available, in particular physical production, and / or physical or planned retrieval from a warehouse and / or physical transport, in particular transport to or from a warehouse or delivery.

[0015] In one embodiment, a parameter dependency of a photochromic tint specified for a lens comprises a tint, for example, an absolute or relative, in particular percentage, photochromic coloration, in particular photochromic darkening, of the lens under the same radiation that excites the photochromism of the lens support at one or more different values ​​of a parameter, in particular of the lens or the support and / or an environment, particularly preferably one or more different temperature values. In one embodiment, this includes - the first parameter dependency of a photochromic tint specified for a first lens - under a specific type of radiation that stimulates the photochromism of the lens support, for example daylight, for example according to one of the standard illuminants of class D (Daylight) of the International Commission on Illumination (CIE), for example D50 (5000 K), D55 (5500 K), D65 (6500 K), and D75 (7500 K), or its UV component, in particular its UV-A component, - at a specific value of a parameter, in a specific version, temperature of the lens or carrier and / or an environment, for example 20°C, - a first tinting, in particular darkening, for example at least 5%, in particular at least 10%, in one embodiment at least 25%, in a further development at least 50%, a (for this lens) maximum (possible) tinting or darkening and / or a reduction of a transmission of visible light by at least 5%, in particular at least 10%, in one embodiment at least 25%, in a further development at least 50%, and - the second parameter dependency of a photochromic tint specified for a second lens - under the same radiation - with the same value of this parameter, in a version of the same temperature, this lens or this carrier and / or the environment, - a second coloring, in particular darkening, which is stronger or more intense than the first coloring or darkening, for example at least 105%, in particular at least 110%, in one embodiment at least 125%, in a further development at least 150%, of the aforementioned first coloring or darkening, and optionally - the third parameter dependency of a photochromic tint specified for a third lens - under the same radiation - with the same value of this parameter, in a version of the same temperature, this lens or this carrier and / or the environment, - a third coloring, in particular darkening, which is stronger or more intense than the first and second coloring or darkening, for example at least 105%, in particular at least 110%, in one embodiment at least 125%, in a further development at least 150%, of the aforementioned second coloring or darkening, wherein the aforementioned first, second and third coloring or darkening is of course always limited upwards by the maximum (possible) coloring or darkening and, if applicable, the lower limit(s) of the other coloring(s).So, purely as an example, if the first coloration reduces the transmittance for visible light by 80%, then the second coloration, again purely as an example, can be a reduction of, for example, 84% (= 105% of the first coloration of 80%) and the third coloration, for example, a reduction of 90% (= 107% of the second coloration of 84%), but of course the third coloration can then be a maximum of 119% of the second coloration (119%·84% = reduction of 100%) and conversely the second coloration can be a maximum of 95% reduction if the third coloration is to be at least 105% of the second coloration (105%·95% = reduction of 100%).

[0016] A darkening mentioned here, in particular expressed as a percentage or %, is in one embodiment a reduction, damping, or attenuation of a transmission, in particular a transmittance T or τ or light transmission value, in the visible spectral range, preferably at a specific wavelength in the visible spectral range, for example at wavelengths in the range between 400 nm and 500 nm, between 500 nm and 600 nm, between 600 nm and 700 nm, or between 700 nm and 780 nm, or an average or averaged transmittance (degree / value) in the visible spectral range, preferably convolved or weighted with the eye sensitivity curve or the relative spectral luminous efficacy V(λ).

[0017] Accordingly, the first parameter dependency of a photochromic tint specified for a first lens can, in particular, comprise a reduction, attenuation, or weakening of such transmission (degree / value) (under a specific radiation that excites the photochromism of the lens support and at a specific value of a parameter, in a specific embodiment, at a specific temperature of the lens or the support, and / or in an environment), in particular, be at least 5%, in particular at least 10%, in one embodiment at least 25%, in a further development at least 50%, of a maximum (possible) reduction, attenuation, or weakening (for this lens), and / or a reduction, attenuation, or weakening of such transmission.The attenuation of such a transmission (degree / value) (compared to such a transmission without this excitation radiation) is at least 5%, in particular at least 10%, in one embodiment at least 25%, and in a further development at least 50%. The second parameter dependence of a photochromic tint specified for a second lens can accordingly be at least 105%, in particular at least 110%, in one embodiment at least 125%, and in a further development at least 150%, of such a reduction or attenuation. The third parameter dependence of a photochromic tint specified for a third lens can in particular be at least 110%, in one embodiment at least 125%, and in a further development at least 150%, of such a reduction or attenuation as mentioned above.

[0018] In one embodiment, the photochromic characteristic of a substrate is achieved by a single- or multi-layered and / or one- or two-sided photochromic coating, in particular with photoresist or the like, and / or a photochromic substrate material. This characteristic can, in particular, include the thickness and / or material of such a coating or such a substrate material. Thus, in one embodiment, substrates exhibiting the same, in particular the first, photochromic characteristic have the same photochromic coating and / or the same substrate material.

[0019] In one embodiment, radiation which can excite photochromism of a substrate comprises UV light, in particular UV-A light, or light with a wavelength in the range of 100 - 420 nm, preferably 315 - 420 nm, in particular 315 - 380 nm, and can in particular be such.

[0020] In one embodiment, one or more of the (attenuation) coatings are (each) single- or multi-layered and / or on one or both sides of the respective substrate or on its eye and / or object side; in another embodiment, on the substrate itself, in a further development, on its possibly present photochromic coating; and / or an interferometric coating or interference coating, in a further development, an antireflective coating (AR coating), or part of an interferometric or interference coating, in a further development, an antireflective coating; or has an interferometric coating or interference coating, in a further development, an antireflective coating. Through the intentional use of different interferometric orInterference coatings, in particular antireflective coatings, in combination with, preferably similar, photochromic substrates for varying the parameter dependence of a photochromic tint, can advantageously also improve the comfort and / or utility of the lens. The lenses can have additional coatings, in particular dirt-repellent or care coatings and / or scratch-resistant or hard coatings. An attenuation coating can be arranged, in particular, between a base body and a photochromic coating of a substrate and / or on a side, in particular a surface, of a photochromic coating of a substrate facing away from the base body and / or on a side, in particular a surface, of a base body of a substrate facing away from a photochromic coating of a substrate. Preferably, an attenuation coating is located relative to a photochromic coating on the object- or environment-side.a photochromic coating relative to an attenuation coating on the eye or eyepiece side, or an attenuation coating in the (light or image) direction of incidence in front of a photochromic coating.

[0021] In one embodiment, two or more of the (attenuation) coatings, which at least partially absorb and / or reflect radiation that can excite photochromism of the respective substrate of the respective lens, have different materials and / or different thicknesses. In a further embodiment, the first and second coatings have different materials and / or different thicknesses, in particular minimum, maximum, and / or average thicknesses, and optionally the first and third coatings and / or the second and third coatings have different materials and / or different thicknesses, in particular minimum, maximum, and / or average thicknesses. This allows the desired different attenuation characteristics to be realized particularly advantageously, especially quickly, precisely, and / or reliably.

[0022] In one embodiment, configuring and / or providing a lens includes providing and / or forming the corresponding (attenuation) coating based on the parameter dependency of a photochromic tint specified for that lens, in particular configuring and / or providing a first lens includes providing and / or forming the first (attenuation) coating based on the first parameter dependency of a photochromic tint specified for that lens, configuring and / or providing a second lens includes providing and / or forming the second (attenuation) coating based on the second parameter dependency of a photochromic tint specified for that lens, and optionally configuring and / or providing a third lens includes providing and / or forming the third (attenuation) coating based on the third parameter dependency of a photochromic tint specified for that lens.In a training course, this configuration and / or provision of a lens includes providing the appropriate carrier from a plurality of carriers that have the same photochromic characteristics.

[0023] Thus, in one embodiment, preferably identical carriers are pre-coated or provided with corresponding different (attenuation) coatings with different attenuation characteristics, depending on the specified parameter dependency of a photochromic tint of the lens to be configured or provided. This allows for improvements in manufacturing, logistics, and / or transport.

[0024] In one embodiment, configuring and / or providing a lens includes selecting a combination of a carrier with a (pre-existing) coating from a plurality of combinations of carriers, which preferably have the same photochromic characteristics, with different coatings based on the parameter dependency of a photochromic tint specified for this lens.

[0025] Thus, in one embodiment, preferably identical carriers are pre-coated with different attenuation characteristics and then selected from this stock according to the specified parameter dependency of a photochromic tint for the lens to be configured or provided. This allows the lenses to be configured or provided particularly advantageously, and especially more quickly.

[0026] In one embodiment, a predetermined parameter dependency of a photochromic tint, in particular the first and second, and optionally third, fourth, and optionally fifth parameter dependencies, each comprise a predetermined temperature dependency of this photochromic tint. Additionally or alternatively, in a further embodiment, a parameter dependency of a photochromic tint is based on a predetermined local area, in an embodiment an ordering location, an ordering country, an ordering climate zone, or the like, at or in which the lens is or has been ordered, or based on a preferably selectable or selected place of use, a preferably selectable or selected country of use, or a preferably selectable or selectedThe selected operating climate zone or the like, in one version a one- or multi-dimensional environmental parameter value assigned to this area, in a further development at least one temperature assigned to this area, for example a, preferably statistical, maximum temperature, minimum temperature and / or average temperature for a specific period, for example one year, the summer months or several years, for example an annual (average / maximum / minimum) temperature, optionally determined over several years. Here, "order" refers to a range of an order or request for the lens, which can facilitate the specification. "Usage" refers to a use of the lens, which can be specified or planned, in particular by selection, thereby improving its practical benefit.In general, a parameter dependency of a photochromic tint in the sense of the present invention can be specified directly or indirectly, in particular by specifying one of several discrete classes or the like, in one embodiment by specifying a parameter value range for which the lens exhibits or is intended to exhibit a certain, in particular advantageous or desired, photochromism or (self-)tinting behavior, for example analogous to "comfort zones" such as those known from sleeping bags or the like, i.e., in particular a (particularly) advantageous parameter range, in one embodiment a temperature range in which the lens exhibits or is intended to exhibit (particularly) advantageous photochromism or (self-)tinting behavior, and / or a parameter range, in one embodiment a temperature range in which the lens (still) exhibits sufficient photochromism or(Self-)tinting behavior is exhibited or intended to be exhibited. The specification of the parameter dependency of a photochromic tint can additionally or alternatively be further abstracted or more indirect, for example "warm" / "cold", "warm" / "temperate" / "cold", or the like.

[0027] The present invention is particularly advantageous for spectacle lenses or spectacle lens blanks, especially corrective or prescription spectacle lenses or prescription spectacle lens blanks.

[0028] According to one embodiment of the present invention, a group of carriers for configuring and / or providing photochromic optical lenses is set up, provided, or used according to a method described herein. Accordingly, one or more, preferably all, carriers of the group have a photochromic characteristic.

[0029] According to one embodiment of the present invention, - one or more of the carriers of a, in particular a, group of, preferably similar, carriers, each (already) with a (first) (attenuation) coating by which radiation, by which photochromism of the respective carrier can be excited, is at least partially absorbed and / or reflected with a first attenuation characteristic, combined and assigned to a predetermined first parameter dependence of a photochromic tint for a lens; and - one or more other carriers of this group, each (already) with a (second) (attenuation) coating, by which radiation, by which photochromism of the respective carrier can be excited, is at least partially absorbed and / or reflected with a second attenuation characteristic, combined and assigned to a predetermined second parameter dependence of a photochromic tint for a lens; and in a further development - one or more further carriers of this group, each (already) with a (third) (attenuation) coating, by which radiation, by which a photochromism of the respective carrier can be excited, is at least partially absorbed and / or reflected with a third attenuation characteristic, combined and assigned to a predetermined third parameter dependence of a photochromic tint for a lens.

[0030] Thus, in particular, a group of lenses or their use is protected, each of which already has a photochromic substrate and a (attenuating) coating described herein, wherein different lenses of the group, preferably different subsets of the group, each with one or preferably several lenses, have different (attenuating) coatings and preferably identical substrates, wherein different predefined parameter dependencies of a photochromic tint are assigned to these different lenses or subsets. In this way, the lenses can be advantageously configured or provided, particularly due to the identical substrates, and / or, particularly due to the assignment, lenses with corresponding parameter dependencies of a photochromic tint can be advantageously selected.

[0031] An assignment of lenses with carriers that are (already) combined or provided with a corresponding (attenuating) coating, and a predetermined parameter dependency of a photochromic tint for the respective lens comprises, in one embodiment, marking the respective lens with an identifier of the respective parameter dependency of the photochromic tint, preferably arranged on the lens, for example "for warm countries / climates / operating conditions", "for temperate countries / climates / operating conditions", "for cold countries / climates / operating conditions" or "for temperatures / maximum temperatures / minimum temperatures / average temperatures in a range between x°C and y°C" or the like, and / or corresponding storage, for example in different storage locations assigned to the different parameter dependencies or the like.

[0032] A computer program product may, in one embodiment, include a storage medium, in particular a computer-readable and / or non-volatile medium, for storing a program or instructions, or with a program or instructions stored thereon. In one embodiment, the execution of this program or these instructions by a system or a controller, in particular a computer or an arrangement of several computers, causes the system or the controller, in particular the computer(s), to execute a procedure described herein or one or more of its steps, or the program or instructions are configured for this purpose.

[0033] In one embodiment, one or more, in particular all, steps of the procedure are fully or partially computer-implemented, or one or more, in particular all, steps of the procedure are fully or partially automated, in particular by the system or its means.

[0034] In one version, the system features the group of carriers.

[0035] As mentioned elsewhere, temperature dependence is a particularly advantageous feature of the present invention, which is therefore explained in detail with reference to this feature, but is not limited to it. Rather, the parameter on which the photochromic tint of the first and second, and optionally third, fourth, and optionally fifth lens(es) depends (first / second / third... parameter dependence of a photochromic tint) can additionally or alternatively include other components or influencing factors affecting the photochromic tint.

[0036] Further advantages and features will become apparent from the dependent claims and the exemplary embodiments. These are shown, in part schematically: Fig. 1: a system or method or group of carriers according to an embodiment of the present invention; Fig. 2: a system or method according to a further embodiment of the present invention; and Fig. 3: a method according to an embodiment of the present invention.

[0037] Fig. Figure 1 shows a system 100, 110 or a method or a group of carriers 10 according to an embodiment of the present invention.

[0038] A user orders a photochromic spectacle lens or a photochromic spectacle lens blank via an input interface 110, which is to be used in a climate zone or a location or country that can be specified at the input interface 110.

[0039] A device 100, designed to simplify in Fig. 1 is represented uniformly, but in one embodiment may also be distributed across several stations, selects one of several lenses based on the parameter dependency specified by the given climate zone or location or country, in one embodiment temperature dependency, of a photochromic tint for the ordered lens, each of which has the same carrier 10 with the same photochromic coatings 11, but different antireflective coatings 20-22, which have different materials and / or thicknesses and thus partially reflect UV radiation, by which the photochromic coating 11 or photochromism of the carrier 10 can be excited, with different attenuation characteristics.

[0040] For example, the anti-reflective coating 20 reflects the least UV radiation, especially UV-A radiation, compared to the other lenses, and allows the most UV-(A) radiation to pass through, so that the Fig. The left lens is suitable for warmer climates because the photochromic coating 11 darkens less at warmer temperatures under the same UV-(A) radiation than at lower temperatures. The antireflective coating 22, for example, reflects UV radiation, especially UV-A radiation, most strongly compared to the other lenses and transmits the least UV-(A) radiation, so that the Fig. The right lens is suitable for colder climates because the photochromic coating 11 darkens more at lower temperatures under the same UV-(A) radiation than at warmer temperatures. The antireflective coating 21 reflects UV radiation, especially UV-A radiation, more strongly than the antireflective coating 20 and less strongly than the antireflective coating 22, and allows more UV-(A) radiation to pass through than the antireflective coating 20 and less UV-(A) radiation than the antireflective coating 22, so that the Fig. One medium lens is suitable for medium climates. Of course, other lenses with different anti-reflective coatings and / or several lenses identical to lens 20, several lenses identical to lens 21, and / or several lenses identical to lens 22, or even just two different anti-reflective coatings, may be provided.

[0041] The carriers 10 of the group of carriers, which are combined with the coatings 20-22, are assigned to the respective predetermined temperature dependence of a photochromic tint for the respective lens, which in Fig. 1 is indicated by corresponding identifiers 30-31. Identifier 30 symbolizes, for example, photochromic suitability for warmer temperatures or a corresponding predefined temperature dependence of a photochromic tint; identifier 31 symbolizes, for example, photochromic suitability for medium temperatures or a corresponding predefined temperature dependence of a photochromic tint; and identifier 32 symbolizes, for example, photochromic suitability for colder temperatures or a corresponding predefined temperature dependence of a photochromic tint. Of course, the classification can also be achieved additionally or alternatively through appropriate sorting, particularly in a warehouse, or in other ways.

[0042] Depending on the specified climate zone, location, or country, and the resulting parameter or temperature dependency of a photochromic tint for the ordered lens, the appropriate lens is selected and made available to the customer.

[0043] Fig. 2 shows in Fig. In the corresponding representation, a system 100', 110' or a method according to an embodiment of the present invention is shown. Corresponding features are identified by identical reference numerals, optionally differentiated by an apostrophe', so that reference is made to the preceding description and differences are discussed below.

[0044] During the execution of the Fig. 2 are the identical carriers 10, which already have the identical photochromic coatings 11 and thus the same first photochromic characteristic, not yet combined with the antireflective coating.

[0045] Upon receipt of a corresponding order, instead of selecting a lens with one of several different anti-reflective coatings 20-22 (see version of the Fig. 1) the corresponding antireflective coating is formed and thereby combined with one of the carriers 10, which already has the photochromic coating 11 (in Fig. 2. For example, the anti-reflective coating 20).

[0046] Fig. Figure 3 shows a method according to one embodiment of the present invention. In step S10, a desired parameter dependence, in one embodiment a temperature dependence, of a photochromic tint is specified, for example, as explained above, by specifying a climate zone or a country or location in which the lens or spectacles with the lens, optionally further processed, are to be used (mainly). Then, in step S20, either as above with reference to Fig. 1 explains, a suitable lens in which one of several identical photochromic substrates is already combined with a suitable one of different antireflective coatings 20-21, is selected or, as above with reference to Fig. 2 explains, one of several identical photochromic substrates is provided with or combined with a corresponding antireflective coating. By following steps S10, S20, as in Fig. As indicated in step 3, the process is repeated several times, specifying different parameter dependencies in step 10, temperature dependencies in one version, and selecting different lenses or applying antireflective coatings in step S20, thus configuring or providing the first, second, and, if necessary, third lenses.

[0047] In the present disclosure, "has an X" does not generally imply an exhaustive list, but is a shorthand for "has at least one X" and also includes "has two or more X" as well as "has Y in addition to X". Although exemplary implementations were explained in the preceding description, it should be noted that a multitude of variations are possible. Furthermore, it should be noted that the exemplary implementations are merely examples and are not intended to limit the scope of protection, applications, or structure in any way.Rather, the preceding description provides the skilled person with a guide for implementing at least one exemplary embodiment, whereby various modifications, particularly with regard to the function and arrangement of the described components, can be made without leaving the scope of protection as defined by the claims and these equivalent combinations of features.

[0048] The particularly preferred variant has been explained here, in which the substrates exhibit the same primary photochromic characteristic. This offers the particular advantage that uniform substrates, especially identical photochromic coatings, can be used. As already explained, in a modification, the substrates can also exhibit different photochromic characteristics, which advantageously allows for the precise and / or variable adjustment of desired temperature dependencies of the photochromic tint of the respective lens.

[0049] Likewise, in addition to or as an alternative to one or more of the antireflective coatings 20-22, another interferometric coating or interference coating can also be used, in particular a mirror coating.

[0050] As already mentioned several times, a (predetermined) temperature (dependence) represents a (predetermined) parameter (dependence) of a photochromic tint in the sense of the present invention, for which the present invention can be used particularly advantageously, but without being limited to this.
