Description

[0001] Description

[0002] Configuring and / or providing photochromic optical lenses

[0003] The present invention relates to a method for configuring and / or providing photochromic optical lenses, a group of photochromic carriers for carrying out a method described here, and a system, a computer program or computer program product for carrying out a method described here.

[0004] Photochromic lenses change color under the influence of corresponding electromagnetic radiation.

[0005] In addition to the corresponding radiation, the photochromic tint can also depend on other influences, such as ambient and / or lens humidity, air pressure, etc., and in particular, temperature. This can lead, for example, to self-tinting glasses that function as intended in a southern country with higher (maximum or average) temperatures, failing in a northern country with lower (minimum or average) temperatures.

[0006] This could mean that at (average) temperatures, the lenses already react with (too) little radiation or too early (too) strongly, or conversely, self-tinting glasses optimized for colder climates react too weakly or too late in warmer climates. Likewise, for example, self-tinting glasses that function as intended in an (average) city may react differently or not as intended in (high) mountains with correspondingly lower air pressures and / or at sea with correspondingly higher air or lens humidity.

[0007] One object of an embodiment of the present invention is to improve photochromic optical lenses and / or the configuration and / or provision of photochromic optical lenses. This object is achieved by a method having the features of claim 1. Claims 10-13 protect a group of carriers configured or used for configuring and / or providing photochromic optical lenses, or a system, computer program, or computer program product for carrying out a method described herein. The subclaims relate to advantageous developments.

[0008] According to one embodiment of the present invention, for configuring and / or providing photochromic optical lenses, two or more optical lenses are configured and / or provided, each

[0009] - a photochromic carrier, preferably a substrate or a base or

[0010] Base body, and

[0011] - at least one coating which at least partially absorbs and / or reflects radiation by which a photochromism of the carrier can be excited and is also referred to here as an attenuation coating for the sake of more compactness without restricting generality.

[0012] According to one embodiment of the present invention, in a further development, one or more of these lenses, which are preferably identical overall or particularly preferably at least with regard to the photochromic carriers and corresponding (attenuation) coatings, are / are different from one another and / or from the other lens(es) to be configured or provided and are therefore referred to as first lens(es) without restriction of generality,

[0013] - based on or depending on a (first) dependency on a (value of a) one- or multi-dimensional parameter(s) (parameter dependency), preferably a desired or target parameter dependency, of a photochromic tint (of the respective lens) (each)

[0014] - a support having a (first) photochromic characteristic, with

[0015] - a (first) (attenuation) coating which combines at least partially absorbing and / or reflecting radiation by which a photochromicity of this carrier can be excited, with a (first) attenuation characteristic.

[0016] According to one embodiment of the present invention, in a further development, in another or several other of the lens(es) (to be configured or provided), which are preferably overall or particularly preferably at least with regard to the photochromic carriers and corresponding (attenuation) coatings, identical to one another and / or different from the first lens(es), in one embodiment of the other of the lens(es) to be configured or provided, and are therefore referred to as second lens(es) without restriction of generality,

[0017] - based on or depending on a second parameter dependency specified for this lens(es), which is different from the above-mentioned first parameter dependency, preferably a second desired or target parameter dependency, of a photochromic tint (of the respective lens) (each)

[0018] - a carrier who

[0019] - a second photochromic characteristic different from the first photochromic characteristic mentioned above, or

[0020] - particularly preferably also has the first photochromic characteristic, with

[0021] - a (second) (attenuation) coating which at least partially absorbs and / or reflects radiation, by means of which a photochromicity of this carrier can be excited, with a second attenuation characteristic which is different from the aforementioned first attenuation characteristic. In one embodiment, in one or more further lenses (to be configured or provided), which are preferably overall or particularly preferably at least with regard to the photochromic carriers and corresponding (attenuation) coatings are identical to one another and / or different from the first and second lens(es), in one embodiment of the other lens(es) to be configured or provided, and are therefore referred to as third lenses without restriction of generality, - on the basis of ordepending on a third parameter dependency, preferably a third desired or target parameter dependency, specified for this lens(es), which is different from the above-mentioned first and second parameter dependency, of a photochromic tint (of the respective lens) (in each case).

[0022] - a carrier who

[0023] - a third photochromic characteristic different from the first and second photochromic characteristics mentioned above, or

[0024] - preferably also has the second photochromic characteristic or particularly preferably also has the first photochromic characteristic, with

[0025] - a (third) (attenuation) coating which at least partially absorbs and / or reflects radiation by which a photochromicity of this carrier can be excited, with a third attenuation characteristic different from the above-mentioned first and second attenuation characteristics.

[0026] Analogously, in one embodiment, one or more further lenses can be configured and / or provided, in particular one or more fourth lenses based on or for a fourth parameter dependency, in a further development one or more fifth lenses based on or for a fifth parameter dependency, etc.

[0027] In one embodiment, the first and second and optionally third and optionally fourth and optionally fifth parameter dependencies designate 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 can in particular comprise, in particular be, a one- or multi-dimensional parameter of the lens itself and / or a one- or multi-dimensional environmental parameter, for example, an ambient and / or lens humidity, an air pressure, or the like, and particularly preferably comprise, in particular specify, an ambient and / or lens temperature.

[0028] 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 (use or ambient) parameters or temperatures, and of realizing such different, in particular desired, parameter dependencies of a photochromic tint of lenses entirely or partially by different (attenuation) coatings, by means of which radiation, by means of which a photochromicity of the preferably structurally identical carriers, which preferably have the same photochromic characteristic, can be excited, is absorbed and / or reflected with different attenuation characteristics, preferably with different strengths.

[0029] In an advantageous embodiment, this can improve production, logistics and / or warehousing, in particular by using carriers that have the same photochromic characteristics. Additionally or alternatively, this can advantageously achieve different parameter dependencies of a photochromic tint of lenses, in particular (also) by using carriers that have different photochromic characteristics. In one embodiment, configuring comprises planning and / or ordering and / or requesting and / or actual or physical production, and can in particular be planning, ordering, requesting and / or actual or physical production. In one embodiment, providing comprises physical making available, in particular physical production, and / or physical or planned retrieval from a warehouse and / or physical transport, in particular delivery or onward transport ora delivery can in particular be a physical making available, in particular a physical production, and / or physical or planned retrieval from a warehouse and / or a physical transport, in particular a delivery or onward transport or a delivery.

[0030] A parameter dependency of a photochromic tint specified for a lens comprises, in one embodiment, a tint, for example an absolute or relative, in particular percentage, photochromic coloration, in particular photochromic darkening, of the lens under the same or the same radiation stimulating the photochromicity of the wearer of the lens at one or more different values ​​of a parameter, in particular of the lens or the wearer and / or an environment, particularly preferably one or more different temperature (values). In one embodiment,

[0031] - the first parameter dependence of a photochromic tint specified for a first lens

[0032] - under a specific radiation which stimulates the photochromism of the wearer of the lens, 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 UV-A component,

[0033] - at a certain value of a parameter, in one embodiment temperature, of the lens or the wearer and / or an environment, for example 20°C,

[0034] - a first coloration, 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) coloration or darkening and / or a reduction of a transmittance for 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

[0035] - the second parameter dependence of a photochromic tint specified for a second lens

[0036] - under the same radiation

[0037] - at the same value of this parameter, in a version of the same temperature, this lens or this support and / or the environment,

[0038] - a second coloration, in particular darkening, which is stronger or more intense than the first coloration 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 above-mentioned first coloration or darkening, and optionally

[0039] - the third parameter dependence of a photochromic tint specified for a third lens

[0040] - under the same radiation

[0041] - at the same value of this parameter, in a version of the same temperature, this lens or this support and / or the environment,

[0042] - a third coloration, in particular darkening, which is stronger or more intensive than the first and second coloration 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 above-mentioned second coloration or darkening, wherein the above-mentioned first, second and third coloration or darkening is of course always (also) limited upwards by the maximum (possible) coloration or darkening and optionally the lower limit(s) of the other coloration(s).So if, purely by way of example, the first coloration is a reduction of the transmittance for visible light by 80%, the second coloration can, again purely by way of example, be a reduction of, for example, 84% (= 105% of the first coloration of 80%) and the third coloration can, for example, be a reduction of 90% (= 107% of the second coloration of 84%), but of course the third coloration can then still be a maximum of 119% of the second coloration (119%-84% = reduction of 100%) and conversely the second coloration can be a maximum of a reduction of 95% if the third coloration is to be at least 105% of the second coloration (105%-95% = reduction of 100%).

[0043] A darkening mentioned here, in particular expressed as a percentage or in %, is in one embodiment a reduction or attenuation or weakening of a transmission, in particular a transmittance T or T or light transmission value, in the visible spectral range, preferably at a specific wavelength in the visible spectral range, for example at a wavelength 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 of an average or mean transmission (degree / value) in the visible spectral range, preferably convolved or weighted with the eye sensitivity curve or the relative spectral luminosity level V(X).

[0044] Accordingly, the first parameter dependency of a photochromic tint specified for a first lens can in particular comprise a reduction or attenuation or weakening of such a transmission (degree of transmission Z value) (under a specific radiation which excites the photochromism of the wearer of the lens and at a specific value of a parameter, in one embodiment a specific temperature, of the lens or of the wearer and / or of 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 (for this lens) maximum (possible) (such) reduction or attenuation or weakening and / or a reduction or attenuation orAttenuation of such a transmission (degree of transmission Z value) (compared to such a transmission (degree of transmission / value) without this stimulating radiation) by at least 5%, in particular at least 10%, in one embodiment at least 25%, in a further development at least 50%. The second parameter dependency of a photochromic tint specified for a second lens can accordingly be in particular at least 105%, in particular at least 110%, in one embodiment at least 125%, in a further development at least 150%, of such a reduction or attenuation or attenuation, the third parameter dependency of a photochromic tint specified for a third lens can in particular be at least 110%, in one embodiment at least 125%, in a further development at least 150%, of such a reduction or attenuation or attenuation or attenuation.

[0045] A photochromic characteristic of a carrier is achieved in one embodiment by a single- or multi-layer and / or single- or double-sided photochromic coating, in particular with photoresist or the like, and / or a photochromic base material of the carrier. In particular, this can include, in particular be, a thickness and / or a material of such a coating or such a base material. Thus, in one embodiment, carriers that have the same, in particular first, photochromic characteristic have, in one embodiment, the same photochromic coating and / or the (same base or base body made of) the same base material.

[0046] In one embodiment, radiation by which a photochromism of a carrier can be excited 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.

[0047] In one embodiment, one or more of the (attenuation) coatings is / are (each) arranged in one or more layers and / or on one or both sides of the respective wearer or on its eye and / or object side, in one embodiment on the wearer itself, in a further development on its photochromic coating, if present, and / or an interferometric coating or interference coating, in a further development an anti-reflective coating (AR coating), or part of an interferometric or interference coating, in a further development an anti-reflective coating, or has an interferometric coating or interference coating, in a further development an anti-reflective coating. Through the deliberate use of different interferometric orInterference coatings, in particular anti-reflective coatings, in combination with, preferably similar, photochromic carriers for varying a parameter dependency of a photochromic tint can advantageously also improve the comfort and / or benefit of the lens. The lenses can have additional coatings, in particular dirt-repellent or care coatings and / or scratch-resistant or hard layers. An attenuation coating can be arranged, in particular, between a base body and a photochromic coating of a carrier and / or on a side, in particular surface, of a photochromic coating of a carrier facing away from the base body and / or on a side, in particular surface, of a base body of a carrier facing away from a photochromic coating of a carrier. An attenuation coating is preferably on the object side or environment side ora photochromic coating arranged relative to an attenuation coating on the eye or ocular side or an attenuation coating arranged in front of a photochromic coating in the (light or image) direction of incidence.

[0048] In one embodiment, two or more of the (attenuation) coatings, which at least partially absorb and / or reflect radiation by which photochromism of the respective wearer of the respective lens can be excited, comprise different materials and / or different thicknesses. In a further development, the first and second coatings comprise different materials and / or different, in particular minimum, maximum and / or average, thicknesses. Optionally, the first and third coatings and / or the second and third coatings comprise different materials and / or different, in particular minimum, maximum and / or average, thicknesses. As a result, the desired different attenuation characteristics can be realized particularly advantageously, in particular quickly, precisely and / or reliably.In one embodiment, configuring and / or providing a lens comprises providing and / or forming the corresponding (attenuation) coating on the basis of the parameter dependency of a photochromic tint specified for this lens, in particular configuring and / or providing a first lens comprises providing and / or forming the first (attenuation) coating on the basis of the first parameter dependency of a photochromic tint specified for this lens, configuring and / or providing a second lens comprises providing and / or forming the second (attenuation) coating on the basis of the second parameter dependency of a photochromic tint specified for this lens, and optionally configuring and / or providing a third lens comprises providing and / or forming the third (attenuation) coating on the basis of the third parameter dependency of a photochromic tint specified for this lens.In a further development, this configuring and / or providing a lens comprises providing the corresponding carrier from a plurality of carriers having the same photochromic characteristic.

[0049] 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 can, in particular, improve production, logistics, and / or transport.

[0050] In one embodiment, configuring and / or providing a lens comprises selecting a combination of a carrier with an (already) formed coating from a plurality of combinations of carriers, which preferably have the same photochromic characteristic, with different coatings based on the parameter dependency of a photochromic tint specified for this lens. Thus, in one embodiment, preferably similar carriers are already pre-provided or provided with different (attenuation) coatings with different attenuation characteristics and then selected from this stock depending on the specified parameter dependency of a photochromic tint of the lens to be configured or provided. This allows the lenses to be configured or provided particularly advantageously, in particular more quickly.

[0051] In one embodiment, in a further development, a predetermined parameter dependency of a photochromic tint, in particular the first and second and optionally third and optionally fourth and optionally fifth parameter dependency (each) comprises a predetermined temperature dependency of this photochromic tint. Additionally or alternatively, in a further development, a parameter dependency of a photochromic tint in one embodiment is based on a predetermined local area, in one 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 on the basis of a, preferably selectable or selected, place of use, a, preferably selectable or selected, country of use, a, preferably selectable orselected, usage climate zone or the like, in one embodiment a one- or multi-dimensional environmental parameter value assigned to this range, in a further development at least one temperature assigned to this range, for example a, preferably statistical, maximum temperature, minimum temperature and / or average temperature for a specific period of time, for example one year, the summer months or several years, for example an annual (average / maximum / minimum) temperature, possibly determined over several years or over several years. "Order" refers to a range of an order or request for the lens, which can make specification easier. "Use" refers to a use of the lens, in particular one that can be specified or planned through the selection, whereby the practical benefit can be improved.In general, a parameter dependency of a photochromic tint within the meaning of the present invention can be or become predetermined directly or indirectly, in particular by specifying one of several discrete classes or the like, in one embodiment by prescribing or specifying a parameter value range for which or in which the lens has or should have a certain, in particular advantageous or desired, photochromism or (self-)tinting (behavior), for example analogous to "comfort zones" as are known from sleeping bags or the like, i.e. in particular a (particularly) advantageous parameter range, in one embodiment temperature range in which the lens has a (particularly) advantageous photochromism or

[0052] (Self-)tinting (behavior) has or should have, and / or a parameter range, in one embodiment, a temperature range in which the lens (still) has or should have sufficient photochromism or (self-)tinting (behavior). The specification of the parameter dependency of a photochromic tint can additionally or alternatively be even more abstracted or indirect, for example "warmTcold", "warm'7" moderate'7" cold", or the like.

[0053] The present invention is particularly advantageous for spectacle lenses or spectacle lens blanks, in particular corrective or prescription spectacle lenses or prescription spectacle lens blanks.

[0054] According to one embodiment of the present invention, a group of carriers is configured, provided, or used for configuring and / or providing photochromic optical lenses according to a method described herein. Accordingly, one or more, preferably all, carriers of the group have a first photochromic characteristic.

[0055] According to one embodiment of the present invention

[0056] - one or more of the supports of a, in particular, group of, preferably similar, supports each (already) provided with a (first) (attenuation) coating, by which radiation, by which a photochromism of the respective support can be excited, is at least partially absorbed and / or reflected, combined with a first attenuation characteristic, and assigned to a predetermined first parameter dependency of a photochromic tint for a lens; and

[0057] - one or more other carriers of this group each (already) with a (second) (attenuation) coating, by means of which radiation, by means of which a photochromism of the respective carrier can be excited, is at least partially absorbed and / or reflected, combined with a second attenuation characteristic and assigned to a predetermined second parameter dependency of a photochromic tint for a lens; and in a further development

[0058] - one or more further carriers of this group each (already) with a (third) (attenuation) coating, by means of which radiation, by means of which a photochromism of the respective carrier can be excited, is at least partially absorbed and / or reflected, combined with a third attenuation characteristic and assigned to a predetermined third parameter dependency of a photochromic tint for a lens.

[0059] Thus, in particular, a group of lenses or the use thereof is protected, each of which already has a photochromic carrier and an (attenuation) coating described here, wherein different lenses of the group, preferably different subsets of the group each with one or preferably more lenses, have different (attenuation) coatings and preferably identical carriers, wherein different lenses or subsets are each assigned different predetermined parameter dependencies of a photochromic tint. In this way, in particular due to the identical carriers, the lenses can be advantageously configured or provided, and / or, in particular due to the assignment, lenses with corresponding parameter dependencies of a photochromic tint can be advantageously selected.

[0060] An assignment of lenses with carriers that are (already) combined or provided with a corresponding (attenuation) coating and a predetermined parameter dependency of a photochromic tint for the respective lens comprises, in one embodiment, a marking of the respective lens with an identifier, preferably arranged on the lens, of the respective parameter dependency of the photochromic tint, for example "for warm countries / climate zones / operating conditions", "for medium countries / climate zones / operating conditions", "for cold countries / climate zones / 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 a corresponding storage, for example in different storage locations assigned to the different parameter dependencies or the like.

[0061] In one embodiment, a computer program product can comprise, in particular be, a storage medium, in particular a computer-readable and / or non-volatile one, for storing a program or instructions or with a program or instructions stored thereon. In one embodiment, execution of this program or these instructions by a system or a controller, in particular a computer or an arrangement of multiple computers, causes the system or the controller, in particular the computer(s), to carry out a method described here or one or more of its steps, or the program or the instructions are configured to do so.

[0062] In one embodiment, one or more, in particular all, steps of the method are fully or partially computer-implemented or one or more, in particular all, steps of the method are fully or partially automated, in particular by the system or its means.

[0063] In one embodiment, the system comprises the group of carriers.

[0064] As mentioned elsewhere, a temperature dependence is a particularly advantageous embodiment of the present invention, which is therefore also explained specifically with reference to this, but is not limited thereto. Rather, the parameter on which the photochromic tint of the first and second, and optionally third, and optionally 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 variables that influence the photochromic tint.

[0065] Further advantages and features emerge from the subclaims and the exemplary embodiments. The following shows, partly schematically:

[0066] Fig. 1 : a system or method or a group of carriers according to an embodiment of the present invention;

[0067] Fig. 2: a system or method according to a further embodiment of the present invention; and

[0068] Fig. 3: a method according to an embodiment of the present invention.

[0069] Fig. 1 shows a system 100, 110 or a method or a group of carriers 10 according to an embodiment of the present invention.

[0070] 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.

[0071] A device 100, which for the sake of simplicity is shown as a unit in Fig. 1, but in one embodiment can also be distributed over several stations, selects one of several lenses for a photochromic tint for the ordered lens on the basis of the parameter dependency specified by the specified climate zone or the specified location or the specified country, in one embodiment temperature dependency, which lenses each have the same carrier 10 with the same photochromic coatings 11, but different anti-reflective 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.

[0072] For example, the anti-reflective coating 20 reflects UV radiation, particularly UV-A radiation, the least compared to the other lenses and transmits the most UV(A) radiation, so that the lens on the left in Fig. 1 is suitable for warmer climates, since the photochromic coating 11 darkens less at warmer temperatures with the same UV(A) radiation than at lower temperatures. The anti-reflective coating 22 reflects UV radiation, particularly UV-A radiation, the most compared to the other lenses and transmits the least UV(A) radiation, so that the lens on the right in Fig. 1 is suitable for colder climates, since the photochromic coating 11 darkens more at lower temperatures with the same UV(A) radiation than at warmer temperatures.The anti-reflective coating 21 reflects UV radiation, in particular UV-A radiation, for example more strongly than the anti-reflective coating 20 and more weakly than the anti-reflective coating 22, and transmits more UV-(A) radiation than the anti-reflective coating 20 and less UV-(A) radiation than the anti-reflective coating 22, so that the middle lens in Fig. 1 is suitable for moderate climates. Of course, further lenses with other anti-reflective coatings and / or several lenses identical to the lens with the anti-reflective coating 20, several lenses identical to the lens with the anti-reflective coating 21, and / or several lenses identical to the lens with the anti-reflective coating 22, or even just two different anti-reflective coatings, can be provided.

[0073] The carriers 10 of the group of carriers combined with the coatings 20-22 are assigned to the respective predefined temperature dependence of a photochromic tint for the respective lens, which is indicated in Fig. 1 by corresponding identifiers 30-31. In this case, the identifier 30 exemplifies a photochromic suitability for warmer temperatures or a corresponding predefined temperature dependence of a photochromic tint, the identifier 31 exemplifies a photochromic suitability for medium temperatures or a corresponding predefined temperature dependence of a photochromic tint, and the identifier 32 exemplifies a photochromic suitability for colder temperatures or a corresponding predefined temperature dependence of a photochromic tint. Of course, the assignment can additionally or alternatively be realized by appropriate sorting, in particular in a warehouse, or in another way.

[0074] Depending on the given climate zone or given location or country and the resulting parameter or temperature dependence of a photochromic tint for the ordered lens, the corresponding lens is selected and made available to the customer.

[0075] Fig. 2 shows a system 100', 110' or a method according to an embodiment of the present invention in a representation corresponding to Fig. 1. Corresponding features are identified by identical reference numerals, possibly differentiated by an apostrophe ', so that reference is made to the above description and differences are discussed below.

[0076] In the embodiment of Fig. 2, the identical carriers 10, which already have the identical photochromic coatings 11 and thus the same first photochromic characteristic, are not yet combined with the anti-reflective coating.

[0077] After receipt of a corresponding order, instead of selecting a lens with one of several different anti-reflective coatings 20-22 (cf. embodiment of Fig. 1 ), the corresponding anti-reflective coating is formed and thereby combined with one of the carriers 10 which already has the photochromic coating 11 (in Fig. 2, the anti-reflective coating 20 is shown as an example).

[0078] Fig. 3 shows a method according to one embodiment of the present invention. In a step S10, a desired parameter dependency, in one embodiment temperature dependency, of a photochromic tint is specified, for example, as explained above by specifying a climate zone or a country or location in which or at which the lens or a pair of glasses with the, optionally further processed, lens is to be (mainly) used. Then, in a step S20, either, as explained above with reference to Fig. 1, a corresponding lens in which one of several identical photochromic carriers is already combined with a corresponding one of different anti-reflective coatings 20-21 is selected, or, as explained above with reference to Fig. 2, one of several identical photochromic carriers is provided or combined with a corresponding anti-reflective coating. By carrying out steps S10, S20, as shown in Fig.3, are run through several times and in step 10 different parameter dependencies, in one embodiment temperature dependencies, are specified and in step S20 different lenses are selected or anti-reflective coatings are formed, first and second and optionally third lenses are configured or provided.

[0079] In the present disclosure, "has an X" generally does not imply an exhaustive list, but is a shortened form of "has at least one X" and also includes "has two or more Xs" and "has Y in addition to X." Although exemplary embodiments have been explained in the foregoing description, it should be noted that numerous modifications are possible. Furthermore, it should be noted that the exemplary embodiments are merely examples and are not intended to limit the scope, applications, or construction in any way.Rather, the foregoing description provides the person skilled in the art with a guide for the implementation of at least one exemplary embodiment, whereby various changes, in particular with regard to the function and arrangement of the described components, can be made without departing from the scope of protection as it results from the claims and combinations of features equivalent to these.

[0080] In the present case, the particularly preferred variant was explained in particular, in which the carriers have the same first photochromic characteristic, which offers the particular advantage that uniform carriers, in particular identical photochromic coatings, can be used. As already explained, in a modification, the carriers can also have different photochromic characteristics, which advantageously allows the desired temperature dependence of a photochromic tint of the respective lens to be adjusted, in particular precisely and / or variably.
