Description

[Technical Field]

[0001] The present invention relates to eyeglass lenses and methods for manufacturing eyeglass lenses. [Background technology]

[0002] Eyeglass lens manufacturers filter a specific wavelength range of incident light, and therefore the object and lens Several products are offered that include features to correct the perceived brightness and color of the wearer's surroundings. These functions are achieved using conventional dyes, photochromic dyes, anti-reflective coatings, or similar materials. All combinations yield satisfactory results, for example, when exposed to UV (ultraviolet) light for the wearer, it darkens. The invention is configured to provide a photochromic lens that dyes as conventionally as The colored lens, photochromic lens, and the front surface is a photochromic film, and the back surface is These are stained lenses.

[0003] The observer's impression of an object's color is determined by three main factors: the light spectrum, the object's absorption, and transmission. It is affected by the reflectance spectrum and / or the sensitivity of the observer's individual photoreceptor cells. The sensitivity of an individual's photoreceptor cells depends on the wavelength and angle that provide biological input to the formation of color perception. This suggests the possibility of an incentive dependent on [something].

[0004] For those who wear eyeglass lenses, the optical characteristics of the lenses are an additional influencing factor. In other words, the reflection spectrum of an object observed by the wearer is the transmission spectrum of the eyeglass lens. It is filtered by a filter.

[0005] The optical filtering characteristics of eyeglass lenses are permanent, for example, compared to conventional eyeglass lenses with dyes. or, for example, non-permanent in eyeglass lenses having a photochromic composition. It is possible.

[0006] In the eyeglass lens industry, photochromic compositions are compositions that darken when exposed to UV radiation. They are considered substances. More specifically, eyeglasses that utilize these compounds for optical filtration. The luminous transmittance of a lens decreases when exposed to UV radiation.

[0007] The following refers to a photochromic composition, which darkens when exposed to UV radiation. In addition to photochromic compositions, so-called negative photochromic compositions are known. Positive photochromic... The optical filtration spectrum modified by the Mick composition shows reduced visual acuity when exposed to UV light. In contrast to the transmittance shown, the optical filtration spectrum modified by the negative photochromic composition When exposed to UV or VIS (visible) radiation, the culvert may also exhibit increased luminous transmittance.

[0008] The photochromic effect on both positive and negative photochromic compositions is due to the following mechanism. It can be based on one of the following. Firstly, at the molecular level, UV radiation affects organic photochromic composition. It consists of energies high enough to induce the reversible breaking of chemical bonds within the framework of an object. In this case, the forward reaction changes the size of the existing pi electron system, and as a result, the VIS (visible) region It induces the formation or transition of absorption bands of photochromic molecules within the region. The reverse reaction of the equilibrium process is: Often thermally induced. A typical example of a photochromic effect based on an organic skeleton. Examples include spiropyran, spirooxazine, diarylethene, azobenzene, and quinone. be.

[0009] A second pathway for altering the optical filtration spectrum of a photochromic composition is conformal change. The energy required for this is absorbed within the visible region of light, for example, the E- This is shown by Z isomerization (NEMOTO, K. et al. Negative pho tochromism of a blue cyanine dye,Chem.Co (See mmun., 2020, 56, 15205-15207).

[0010] Other mechanisms that produce photochromic effects may also be possible. For example, inorganic photochromic Mick composition and, for example, based on silver oxide and cerium oxide-doped lithium aluminosilicate There are products available that are named after specific substances and compositions, including photochromic materials. Furthermore, the outline describing the relevant mechanisms for the photochromic effect is by TIAN, H. .,ZHANG,J.(Ed),Photochromic Materials:Pr. eparation,Properties and Applications,20 16,Wiley-VCH Verlag GmbH&Co.KGaA,DOI:10. 1002 / 9783527683734, especially chapter 1: NAKATANI, K. et al.,Introduction:Organic Photochrom Provided by ic Molecules.

[0011] Substances exhibiting negative photochromic effects are not limited to azobenzene and spirobenzone. Spiropyran derivatives including pyran, dihydropyrenes such as dimethyldihydropyrene, ste Imidazole radica such as Nhaus salt, 1,1'-binaphthyl cross-linked imidazole dimer, etc. It contains a complex and cyanine dyes such as blue cyanine dye (BCy).

[0012] Chemical groups of negative photochromic compositions and obvious examples include, for example, dihydropyrene(phosphorus). The "illumination" effect (i.e., conversion to a colored state) caused by opening / closing the gate, 1,1'-binaf Chill-crosslinked phenoxyl-imidazolyl radical complex (by forming a radical complex) The resulting "illumination" effect and blue cyanine dye (BCy; produced by EZ isomerization) This is a "lighting" effect.

[0013] Specific examples of negative photochromic materials and compositions are, in particular, provided by YAMAGUCHI, T. et al.Fast Negative Photochromism of 1,1 '-Binaphthyl-Bridged Phenoxyl-Imidazolyl Radical Complex,J.Am.Chem.Soc.2016 138( 3),906-913,NEMOTO,K.et.al.Negative photo chromism of a blue cyanine dye,Chem.Comm un.,2020,56,15205-15207,FUNASAKO,Y.et al .Synthesis,Photochromic Properties,and C rystal structures of salts containing a Pyridinium-Fused Spiropyran:Positive and Negative Photochromism in the Solution and Solid State,J.Phys.Chem.B2020,124,33 ,7251-7257,SARKAR,R.et al.Electronic Exc. ited States and UV-Vis Absorption Spectr a of the Dihydropyrene / Cyclophanediene P hotochromic couple: a Theoretical Investi gation,J.Phys.Chem.A 2020,124,8,1567-157 It is disclosed in section 9.

[0014] A single molecule whose solvent or embedding matrix does not undergo simultaneous changes in its characteristics upon deactivation / activation. In addition to negative photochromism, macroscopic effects are also observed with deprotonating dyes (indicator dyes). This is achieved by embedding in a matrix, which is UV and / or VI. It responds to each of the S-lights.

[0015] For example, a photosensitive matrix that releases protons (pH change through photoacid in a metastable state). This can promote the protonation of colored indicator dyes, and the proton form is less colored. It is either absent or completely uncolored. Photo-induced proton release and pH-dependent absorption of the dye. An example of their effects on the photometric spectrum is found in ALGHAZWAT, O. et al., RED. -light responsive metastable-state photo As shown in Acid, Dyes and Pigments 171, 107719 .

[0016] Generally, positive photochromic compositions used in eyeglass lenses emit light in the UV range. The wearer can perceive the darkening of the eyeglass lenses (L * a * b * L of color space * value This darkening may be associated with an undesirable change in perceived color (L * a * b *Color space of a * and b * values).

[0017] As a result, the color impression and perceived contrast of the wearer of the same object can vary depending on the U V filtering conditions of the spectacle lenses.

[0018] Moreover, spectacle lenses with a positive photochromic composition cannot change the color impression of the wearer under different UV filtering conditions without changing the perceived lightness due to the change in visual transmittance. Conventional spectacle lenses containing dye substances cannot respond to different UV filtering conditions in the environment with any change in their optical filtering spectrum, for example, neither a change in perceived lightness nor a change in color.

[0019] Furthermore, a quantitative description of the contrast sensitivity is reported in the prior art by BARTEN, P. Formula for t he contrast sensitivity of the human eye , Proc. SPIE 5294 Image Quality and System Performance, 18 December 2003; doi:10.111 7 / 12.537476, where different influencing factors of the contrast sensitivity of human vision are shown (see Figure 4 of the published publication). Shadow pairs can affect the noise on the contrast sensitivity of the eye. BARTEN, P. shows that the contrast of an object is a function of the LS / L ratio, where LS is the ambient luminance and L is the luminance of the object. Therefore, it is difficult to see a dark object in an overly bright scene.

[0020] ​​​​​​​In addition, LINGELBACH, B. et al. have shown that contrast sensitivity (perception) is also spectral This indicates that it depends on the varying sensitivities of the eye directed towards different parts of the light. That is, diffused light Loudness generates a lot of "noise" through the visual system, which makes important objects appear in the background. It becomes more difficult to distinguish from (LINGELBACH, B. et al. Journey) nal of ASTM International,January 2005,V ol.2, No.1:DOI:10.1520 / JAI11972).

[0021] According to LINGELBACH, B. et al., conventional eyeglass lenses that enhance contrast This attempts to remove the "noise" in the spectrum in the background, and the different spectra of important objects. The chrominance is left as untouched as possible, thereby enhancing contrast. Regarding this, it works best under specific default lighting, for example, bright light for ski goggles. It is clear that it works. However, conventional techniques enhance the contrast of the eye. Mirror lenses are used under various conditions such as changes in the overall level of the ambient spectrum and / or brightness. It is not possible to improve the contrast sufficiently.

Parameter L * a * and b * The calculation method is D IN EN ISO / CIE 11664-4:2019,Colourimetry- Part 4: CIE 1976L * a * b * Explicitly indicated in the color space. .

[0037] The term "adjacent to each other laterally" means that two compositions are in the same plane, for example, within one coating. This refers to an arrangement in which two elements are placed in contact with or without contact with each other. For example, two compositions are arranged in a way that allows them to be placed in contact with each other. Pixels can be arranged in a xel-like form, either touching or not touching.

[0038] The term "light," when used alone, refers to electromagnetic radiation that can directly evoke human vision. Radiation (visible light) refers to electromagnetic radiation with wavelengths between 380 nm and 780 nm.

number

[0040] In other words, luminous transmittance is the amount of light that passes through a medium and can be perceived by the human eye. 65. This is a measure of the amount of electromagnetic radiation emitted from a reference light source, such as a light source.

[0041] The term "composition" refers to a chemical substance or a mixture of different chemical substances.

[0042] The term "composition exhibiting negative photochromic characteristics" is used to describe substances such as negative photochromic materials. This refers to a dynamic composition. Compositions exhibiting negative photochromic characteristics are in the UV and / or VIS range. When emitted within the surrounding area, macroscopically, it changes from a state of lower luminous transmittance to a state of higher luminous transmittance. It changes to this. This can occur if the composition actually contains negative photochromic material. A composition containing, consisting of, or exhibiting negative photochromism, at least one This is because it contains a photosensitive matrix having two indicator dye substances.

[0043] The term "composition exhibiting positive photochromic characteristics" is used to describe substances such as positive photochromic materials. This refers to a dynamic composition. Compositions exhibiting positive photochromic characteristics are in the UV and / or VIS range. When emitted within the surrounding area, macroscopically, it changes from a state of higher luminous transmittance to a state of lower luminous transmittance. It changes to this. This can occur if the composition actually contains positive photochromic material. A composition containing, consisting of, or exhibiting positive photochromism, at least one This is because it contains a photosensitive matrix having two indicator dye substances.

[0044] The term "photosensitive matrix" is used to incorporate, for example, embed indicator dyes. This refers to a chemical composition that reacts in response to the emission of light in the UV and / or VIS range. For example, this involves the release of protons due to a pH change through a metastable photoacid. Obtain. The response is an indicator dye substance that results in a macroscopic presentation of positive or negative photochromism. The equilibrium between the protonated and deprotonated forms, or the negative and / or positive photochromic It can be used to influence the equilibrium between the active and inactive states of a substance. ru.

[0045] The term "photochromism" is induced by the absorption of UV radiation and / or VIS radiation. For example, the reversible transformation of the chemical species between two forms or states of an isomer, such as a molecule. This refers to the two forms, which differ in the visible part of the electromagnetic spectrum, i.e., 380 nm to 780 nm. Absorption spectra can essentially be shown, or they represent two forms of a different chemical species or Each state can be transformed between the other, and these two forms or states are visible in the electromagnetic spectrum. The parts exhibit different absorption spectra.

[0046] The two states or forms are, respectively, active states or forms (in the UV and / or VIS range). This is referred to as the post-emission state and the inactive state or form (before emission in the UV and / or VIS range). The process of changing an inactive state or form to an active state or form is called activation, and the active state The process of changing a state or form into an inactive state or form is called deactivation.

[0047] The required wavelengths of UV and / or VIS radiation to induce this deformation are electric to the antibonding orbitals. It depends on the energy required to launch the offspring. Therefore, the wavelength is related to the molecule. It is specific to [the substance]. Along with the absorption spectrum, the luminous transmittance is affected accordingly. Both The visible light transmittance for spectacle lenses containing photochromic material in this state is DIN EN A standard as described in ISO 8980-3:2014-03, Section 7.5. It can be determined by a standard procedure. For luminous transmittance after UV and / or VIS irradiation. The ratio of luminous transmittance in that thermodynamically stable state is called the photochromic response. (DIN EN ISO 8980-3:2014-03,Section6.4.1 (See reference). Thus, the photochromic composition (photochromic material) is further A composition whose luminous transmittance can be reversibly changed depending on the illuminance and wavelength of the optical radiation falling on it. Yes (DIN EN ISO 13666:2019-12, Section 3.3.5) (See reference), photochromic eyeglass lenses respond to the illuminance and wavelength of the optical radiation they are exposed to. These are eyeglass lenses that depend on and reversibly change their luminous transmittance (DIN EN ISO See 13666:2019-12, Section 3.5.11.

[0048] "Positive photochromism" refers to the luminous transmittance of a composition in its active state being lower than in its inactive state. This means that activation occurs via emission in the UV and / or VIS range. Therefore, the photochromic response is positive. In relation to this, the terms "higher" and "more" "Low" is a relative concept used only to compare the luminous transmittance of two states. Please note that absolute recommendations regarding luminous transmittance are not permitted.

[0049] "Negative photochromism" refers to the phenomenon where the active state of a composition exhibits a higher luminous transmittance than the inactive state. This means that activation occurs via emission in the UV and / or VIS range. Therefore, the photochromic response is negative. This is because the thermally stable colored form (inactive state) When irradiated with light, the (state) isomerizes into a metastable colorless form (active state), and the resulting colorless form is This is a photochromic reaction that thermally reverts to the initial colored form.

[0050] The term "negative photochromic material" refers to a substance that exhibits negative photochromism due to its chemical structure. This refers to a chemical substance that exhibits qualitative characteristics. Its molecular structure is, for example, its emission in the UV and / or VIS range. When activated, it changes from a state of lower luminous transmittance to a state of higher luminous transmittance. Lower luminous transmittance corresponds to a thermodynamically stable state.

[0051] The term "positive photochromic material" refers to a substance that exhibits positive photochromism due to its chemical structure. This refers to a chemical substance that exhibits qualitative characteristics. Its molecular structure is, for example, its emission in the UV and / or VIS range. When activated, it changes from a state of higher luminous transmittance to a state of lower luminous transmittance. The state with higher luminous transmittance corresponds to the thermodynamically stable form.

[0067] A composition exhibiting negative photochromic properties is, for example, one of the lens substrates for eyeglass lenses. Alternatively, it may be present on multiple surfaces, and / or it may be incorporated into an eyeglass lens substrate. ru.

[0068] Compositions exhibiting negative photochromic characteristics include dye substances and / or positive photochromic compositions. Compared to conventional eyeglass lenses containing only material, they differ in radiation conditions in the UV and / or VIS range. Under certain lighting conditions, the achievable visual effects include color shift, color stability, contrast adaptation, and other factors. It can be widened. Therefore, these eyeglass lenses can absorb light according to the wearer's individual needs. You can customize the clef better.

[0069] Specifically, compositions exhibiting negative photochromic characteristics are emitting light in the UV and / or VIS range. When illuminated, it is possible to shift the color without changing the brightness or with little to no change. To obtain. Brightness is, for example, L * a * b * L in color space * By observing the parameters, It can be produced. In other words, L * a * b * a in the color space * and b * The parameter is L * Without changing or with minimal change to the parameters, under different UV radiation conditions It is possible to obtain it.

[0070] For example, in interior spaces such as offices, negative photochromic features, i.e., eyeglass lenses, are yellow Using a composition that may appear colored, eyeglass lenses that absorb blue light It may be desirable to have it. However, light conditions include outdoor sunlight conditions including UV radiation. As a result, changes occur, for example, when a person wearing eyeglass lenses leaves the office, the building of the office... When going outside, exposure to UV radiation can change the absorption spectrum of eyeglass lenses. This process causes a decrease in blue light absorption, meaning that eyeglass lenses have a yellowish tint. It doesn't appear colorless; rather, it appears colorless.

[0071] Examples of compositions exhibiting negative photochromic characteristics and compositions exhibiting positive photochromic characteristics include For example, they could be arranged in a line like small droplets, or, for example, layer by layer or pixel by pixel. They can be stacked so that each one is layered on top of the others.

[0072] Combining a composition exhibiting negative photochromic characteristics with a composition exhibiting positive photochromic characteristics By combining them, conventional methods containing only dye substances and / or positive photochromic compositions are available. Compared to eyeglass lenses, it can produce even more different visual effects.

[0073] Furthermore, compositions exhibiting negative photochromic characteristics and compositions exhibiting positive photochromic characteristics Eyeglass lenses containing materials adjust their optical filtering characteristics accordingly, thereby controlling ambient light emission. Dynamic contrast absorption under various conditions such as changes in the overall level of luminance and / or brightness. It is possible to capture it. In other words, the composition exhibiting negative photochromic characteristics contained within the spectacle lens. Compositions exhibiting material and positive photochromic properties are used to improve contrast. It is possible.

[0074] For example, the color of eyeglass lenses becomes more reddish when the sun is low and whiter when the sun is high. While it can vary in its bluish emission spectrum, it maintains a nearly constant luminous transmittance. This is because eyeglass lenses have the characteristic of enhancing their contrast under a wider variety of ambient light conditions. It can be maintained.

[0075] At the same time, while the illuminance changes, for example, for an observer moving from the sun to the shade while driving... In contrast, maintaining that spectrum makes it equally possible to improve contrast. In such situations, compositions exhibiting negative photochromic characteristics and positive photochromic characteristics Eyeglass lenses containing the characteristic composition can adjust their light transmission while maintaining their color tone. This is possible. Therefore, compared to conventional eyeglass lenses that enhance contrast, eyeglass lenses can do this. This has the advantage of working under a much wider range of lighting conditions.

[0076] For example, a composition exhibiting negative photochromic features has at least one positive photochromic It may contain a substance. In other words, one or more compositions exhibit positive photochromic characteristics. It contains or may consist of a positive photochromic material. The realization of positive photochromic properties allows, in the simplest case, to create a single material, i.e., one positive f Because photochromic materials are required, it has the advantage of a simple and practical implementation.

[0077] For example, at least one positive photochromic material is TIAN, H., ZHANG, J. (Ed), Photochromic Materials: Preparation. n,Properties and Applications,2016,Wiley -VCH Verlag GmbH&Co.KGaA,DOI:10.1002 / 978 It may be a substance like those disclosed in 3527683734. In other words, one or more The substances described can be used as compositions exhibiting positive photochromic characteristics.

[0078] In certain advanced forms of these spectacle lenses, compositions exhibiting negative photochromic characteristics and positive photochromic characteristics are used. Compositions exhibiting tochromic features are adjacent to each other laterally, for example, side by side on spectacle lens surfaces. On the surface, for example, the front and / or rear, specifically, at least on the front for the reasons mentioned above. It is possible.

[0079] To obtain a laterally adjacent arrangement, a composition exhibiting negative photochromic characteristics and positive photochromic characteristics are used. Compositions exhibiting tochromic characteristics can be obtained, for example, by using an inkjet printing method. The surface can be coated at a pixel-by-pixel level. For example, the coating exhibits negative photochromic properties. The pixel may alternately contain pixels of a composition and a composition exhibiting positive photochromic characteristics. The elements can be arranged in contact with each other or separately.

[0080] For example, negative photochromic material and positive photochromic material are adjacent to each other in the lateral direction. It can then be placed on the surface of the spectacle lens material.

[0081] The described lateral adjacent arrangement may contain negative photochromic particles that may affect color and / or brightness. To reduce or avoid the interaction between compositions exhibiting photochromic properties and compositions exhibiting positive photochromic properties. This has the advantage of allowing the following changes to the filter spectrum. This increases the degree of freedom. Moreover, in a side-by-side arrangement, the overall spectrum is not simply added together. Therefore, the calculation and simulation of the resulting overall spectrum are easier. This has the advantage of a further specific development of the spectacle lens of the present invention, negative pho Compositions exhibiting tochromic properties, photosensitive matrix having at least one indicator dye substance The filter spectrum, or smear spectrum, allows for the macroscopic observation of negative photochromism. The effects of matrix changes induced by illumination within the UV and / or VIS range. It may contain a substance that is subject to light, or its photosensitive matrix, i.e., it may consist of that substance. Dipene dyes can be incorporated into the photosensitive matrix.

[0082] A photosensitive material having at least one indicator dye substance to obtain a negative photochromic effect. The main advantage of using a matrix is ​​that it takes into account the specific needs of eyeglass lenses and their manufacture. The ability to adjust the properties of the matrix is, for example, It can be adjusted to adhere well to the surface of the spectacle lens substrate. Furthermore, Matri The tools are related to the manufacturing process, including cleaning, polishing, spinning, and further coating. It can be modified to improve resistance to image manipulation.

[0083] In a second aspect, the present invention provides a further spectacle lens. The spectacle lens is negative photo The composition includes a composition exhibiting chromicity. The composition exhibiting negative photochromicity includes at least One indicator dye, i.e., the filter spectrum, exhibits macroscopically negative photochromism. A matrix can be made to be illuminated by UV and / or VIS light so that it can be activated It contains a photosensitive matrix having a substance that is affected by color change. The indicator dye substance is photosensitive. It can be incorporated into the sex matrix.

[0084] A photosensitive material having at least one indicator dye substance to obtain a negative photochromic effect. The main advantage of using a matrix is ​​that it takes into account the specific needs of eyeglass lenses and their manufacture. The ability to adjust the properties of the matrix is, for example, It can be adjusted to adhere well to the surface of the spectacle lens substrate. Furthermore, Matri The tools are related to the manufacturing process, including cleaning, polishing, spinning, and further coating. It can be modified to improve resistance to image manipulation.

[0085] Compositions exhibiting negative photochromicity are dye substances and / or positive photochromic compounds. Compared to conventional spectacle lenses containing only the material, different lighting conditions within the UV and / or VIS range Under certain conditions, you can expand the range of achievable visual effects such as color shift, color stabilization, and contrast adaptation. Therefore, with these eyeglass lenses, the absorption spectrum of the eyeglass lens is tailored to the individual wearer. It can be better customized to meet specific needs.

[0086] Specifically, compositions exhibiting negative photochromicity are exposed to UV and / or VIS range light. It may be possible to enable color shifts in bright conditions without changing or significantly changing the brightness. Brightness is, for example, , L * a * b * L in color space * It can be detected by observing the parameters. In other words, L * a * b * a in the color space * Parameter and b * The parameter is L * Parame It can be changed under different UV radiation conditions without changing or slightly changing the type. ru.

[0087] For example, in interior spaces such as offices, compositions exhibiting negative photochromicity are used. Eyeglass lenses absorb blue light, meaning that eyeglass lenses can appear yellowish. This may be desirable in some cases. However, if the light conditions are similar to outdoor sunlight conditions including UV radiation... If this changes, for example, if a person wearing eyeglass lenses leaves the office, the office building... When going outside, the absorption spectrum of eyeglass lenses changes due to exposure to UV radiation. This results in a decrease in the absorption of blue light, meaning that eyeglass lenses will have a yellowish tint. Instead, it appears colorless.

[0088] In a particular evolution of the spectacle lens according to the first or second aspect of the present invention, a negative photochromic A composition exhibiting mic properties may contain at least one negative photochromic substance.

[0089] In other words, a composition exhibiting negative photochromicity is one or more negative photochromic properties. It may contain or be composed of photochromic materials. Negative photochromic materials To achieve photochromicity, in the simplest case, only one material is needed, namely one negative photochromic Since it only requires chromic substances, it has the advantage of being easy to implement and practical.

[0090] For example, at least one negative photochromic material is a negative photochromic material and Specific examples of compositions are disclosed in the references cited in the background section. It could be such a substance.

[0091] In other words, one or more of the substances mentioned are compositions that exhibit negative photochromicity. It can be used as such.

[0092] In a further specific development of the spectacle lens according to the first or second aspect of the present invention, the spectacle lens The composition may include an eyeglass lens substrate, and exhibits negative photochromicity, and the eyeglass lens base It can be placed on the surface of a board.

[0093] For example, a composition exhibiting negative photochromicity may be used on one or more surfaces of an eyeglass lens substrate. It may exist as a coating on a surface, for example, its front and / or rear surface. In particular, negative photo The chromic composition can be placed at least on the front surface of the spectacle lens substrate. This allows the effects induced by illumination within the UV and / or VIS range to be controlled by UV The spectacle lens substrate contains a UV absorber that prevents radiation from passing through the spectacle lens substrate. It can be caused even in this case.

[0094] Compositions exhibiting negative photochromicity are directly coated onto the surface of spectacle lens substrates. It can be, that is, it can be placed in direct contact with the material of the spectacle lens substrate or the spectacle lens substrate A material and a coating comprising or consisting of a composition exhibiting negative photochromicity. One or more other coatings may be present between them. In any case, the spectacle lens base When viewed from the board, the surface has negative photochromic properties such as anti-reflective coatings and hard coats. One or more additional coatings comprising or consisting of a composition exhibiting the above may be arranged. ru.

[0095] A composition exhibiting negative photochromicity is placed in direct contact with the surface of an eyeglass lens substrate. This can improve the adhesion and durability of the coating.

[0096] Placing a composition exhibiting negative photochromicity on the surface of an eyeglass lens substrate requires, For example, known coating procedures can be used, making it easy to implement and practical. This has the advantage of allowing the optical structure of the spectacle lens substrate to be realized in advance. This makes it possible to semi-complete the coating process with compositions exhibiting negative photochromicity. Lens blanks or finished lens blanks can be used. Therefore, several The same semi-finished or finished lens blanks are produced simultaneously, and in a later stage... For example, it is possible to coat it in a different way with a different composition that exhibits negative photochromicity. can.

[0097] Instead of placing a composition exhibiting negative photochromicity on the surface of the spectacle lens substrate, Alternatively, compositions exhibiting negative photochromicity may be incorporated into spectacle lens substrates. .

[0098] Such integration can be achieved, for example, by a diffusion process. For example, negative An eyeglass lens substrate can be immersed in a bath containing a composition exhibiting photochromic properties, thereby A composition exhibiting negative photochromic properties can be diffused into a substrate material.

[0099] Compared to coating, embedding into a substrate may offer advantages in terms of mechanical stability. .

[0100] In a further specific development of the spectacle lens according to the first or second aspect of the present invention, the spectacle lens The dye may contain dye substances. For example, dye substances may be aprotonable, exhibiting only one state. It can be a dye substance that changes its absorption spectrum when illuminated in the UV and / or VIS range. That is not possible.

[0101] For example, eyeglass lenses may contain a composition exhibiting negative photochromicity and a dye substance. However, the composition does not contain positive photochromicity, or the spectacle lens does not contain negative photochromicity. A composition exhibiting tochromic properties, a dye substance, and a composition exhibiting positive photochromic properties It may include.

[0102] Suitable dyes include, for example, Dianix Yellow AM-42, Serile ne Scarlet G-LS, Dianix Turquoise S-BG, Te rasil Blue 3 RL-01, Teratop Blue GLF, Doro spers Red KKR, Teratop Pink 3G, Dianix Ora nge SG and CRX powder dyes, e.g., fluorescent yellow 5944, lemon yellow 80 43, Gold Yellow 3441, Orange 5945, Orange 3439, Scarlet 3443, Red 8153, Pink 3442, Fuchsia 8168, Purple 3735, Mo Blue 3449, Aubergine 8169, Blue 3437, Night 3438, Blue 57 70, Sky 8170, Anise Green 6755, Green 3450, Green 3467 Dark Green 8171, Ocher 8172, Brown Pink 3466, Olive Brown Un 3446, Smoke 3447, Brown 6785, Neutral Gray 3444, A Ian Grey 8173, Grey Blue 3445, Grey Green 5661, Black 58 It is 94.

[0103] If the spectacle lens further contains a dye substance, the dye substance and / or positive photochromic composition Compared to conventional eyeglass lenses that only contain material, it is possible to obtain many more different visual effects. ru.

The method is as follows: The process includes steps: providing an eyeglass lens substrate; and demonstrating negative photochromicity. A composition is placed on the surface of an eyeglass lens substrate and / or exhibits negative photochromicity. Steps include: incorporating the product into an eyeglass lens substrate; and creating a composition exhibiting positive photochromicity. A composition that is disposed on the surface of an eyeglass lens substrate and / or exhibits positive photochromicity is used for eyeglass lenses. Steps to integrate it into the circuit board.

[0105] Compositions exhibiting negative photochromicity and / or positive photochromicity Placing it on the surface of the spectacle lens substrate is done by spin coating, dip coating Achieved through coating procedures such as spray coating and inkjet printing. Obtainable. Incorporation into spectacle lens substrates is, for example, a composition exhibiting negative photochromicity. Diffusion processes that may lead to the physical incorporation of compositions exhibiting / or positive photochromicity This can be appropriately achieved by, for example, absorption or chemical bonding to the material of the spectacle lens substrate.

This manufacturing method can be used to produce. Therefore, specific examples and positive photocri Negative photochromicity includes compositions and / or combinations with dye substances that exhibit photochromicity. The description of the composition shown is equally applicable to this manufacturing method. Therefore, refer to the eyeglass lens. The advantages mentioned above are related to the manufacturing method.

Compositions exhibiting tochromic properties and compositions exhibiting positive photochromic properties include, for example, droplets. They can be arranged side by side or stacked as a structure, for example, layer by layer.

[0108] In a specific evolution of the method according to a third aspect of the present invention, negative photochromicity is exhibited. The composition may include a photosensitive matrix having at least one indicator dye substance.

[0109] In a fourth aspect, the present invention provides a further method of manufacturing an ophthalmic lens.

The composition exhibiting negative photochromic properties comprises a photosensitive matrix having at least one indicator dye substance. Disposing the composition exhibiting negative photochromic properties on the surface of the ophthalmic lens substrate can be achieved by coating procedures such as spin coating, dip coating, spray coating, inkjet printing, etc. Incorporation into the ophthalmic lens substrate can be appropriately achieved, for example, by a diffusion process, such as a diffusion process leading to physical uptake of the composition exhibiting negative photochromic properties, for example, by absorption or chemical bonding to the material of the ophthalmic lens substrate. Illustratively, the manufacturing method can be used to manufacture an ophthalmic lens according to the second aspect of the present invention as described above, i.e., an ophthalmic lens comprising a composition exhibiting negative photochromic properties, which comprises a photosensitive matrix having at least one indicator dye substance. Therefore, the description of the composition exhibiting negative photochromic properties, including specific examples and combinations with compositions and / or dye substances exhibiting positive photochromic properties, is equally applicable to the present manufacturing method. Thus, the advantages described above in reference to the ophthalmic lens are relevant to the manufacturing method.

[0116] Exemplary embodiments of the present spectacle lens will be described with reference to FIGS. 1 to 9. The spectacle lens 1 of the exemplary embodiment contains a composition 2 that exhibits negative photochromism, respectively.

[0117] FIG. 1 shows a pair of spectacles 100 having two single vision spectacle lenses 1, one for the wearer's right eye and one for the left eye. The two spectacle lenses 1 are attached to a spectacle frame 101 and separated by a bridge 102 of the spectacle frame 101. The spectacle lenses 1 can be, according to the needs of the wearer, thus zero, plus or minus lenses.

[0118] FIGS. 2a to 2e show different embodiments of the spectacle lens 1 that can be incorporated into the spectacles 100 as shown in FIG. 1. are shown.

[0119] In the first embodiment (not included in the gist of the claims) according to FIG. 2a, the spectacle lens The first element includes, for example, a spectacle lens substrate 6 made of a polymer material. Plate 6 shows the position of the wearer's eye 10 when the spectacle lens 1 is worn in front of the wearer's eye. It has a front 7a and a rear 7b as defined accordingly. However, unless otherwise specified, A change to the surface of the front 7a can be replaced with a change to the rear 7b, and vice versa.

[0120] In the front surface 7a of the spectacle lens substrate 6, the composition 2 exhibiting negative photochromicity is, for example, For example, they are arranged in the form of separate droplets or continuous layers. Negative photochromicity is negative Composition 2 obtained by photochromic material 3, i.e., exhibiting negative photochromicity. And negative photochromic material 3 is the same. Composition exhibiting negative photochromicity 2 may cover the entire front surface 7a or only a part of it.

[0121] Furthermore, one or more additional coatings (not shown), such as anti-reflective coatings, may be applied. And / or a hard coat may be applied. Such additional coatings , between surfaces 7a, 7b and composition 2 exhibiting negative photochromicity or negative photochromicity It can be placed on top of composition 2 which exhibits locking properties.

[0122] Figure 2b shows another embodiment of the eyeglass lens 1. The embodiment described in relation to Figure 2a is different from the embodiment described in Figure 2a. In contrast, composition 2, which exhibits negative photochromicity, contains a negative photochromic substance 3. First, it includes a photosensitive matrix 4 having an indicator dye substance 11 instead.

Therefore, negative The properties of composition 2 exhibiting photochromicity and composition 8 exhibiting positive photochromicity To use both to change the optical properties of eyeglass lens 1 without affecting each other. It is possible.

[0125] Figure 2d shows another embodiment of the eyeglass lens 1. Hereinafter, the embodiment described with respect to Figure 2a In comparison to the morphology, composition 8, which exhibits positive photochromicity, is further arranged on the front surface 7a. Composition 8, which exhibits positive photochromicity, consists of a positive photochromic substance 5.

[0126] Composition 2 exhibiting negative photochromicity and composition 8 exhibiting positive photochromicity are They are arranged as a stack on the surface 7 of the spectacle lens substrate 6. In Figure 2d, negative photochromic The layer containing composition 2 exhibiting photochromic properties is directly placed on the front surface 7a, while the positive photochromic layer Composition 8 exhibiting negative photochromicity is a layer on top of the layer containing composition 2 exhibiting negative photochromicity. They are arranged. However, the order is changeable, i.e., exhibiting positive photochromicity. A layer containing composition 8 can be placed directly on the front surface 7a, while exhibiting negative photochromicity. Composition 2 is positioned as a layer on top of a layer containing composition 8 which exhibits positive photochromicity. By depositing it as a layer, it became possible to use conventional coating procedures. Therefore, it is easy to implement.

[0127] Figure 2e shows another embodiment of the eyeglass lens 1. The embodiment described in relation to Figure 2a is different from the embodiment described in Figure 2a. In contrast, the spectacle lens substrate 6 contains a dye substance 9 that leads to the permanent color of the spectacle lens 1. As shown in Figure 2e, the spectacle lens substrate 6 containing the dye substance 9 is similar to Figure 2b and Please note that this can be combined with the embodiment described with respect to Figure 2c.

[0128] The optical effects obtainable with this spectacle lens 1 are described below with reference to Figures 3 to 8. To clarify, Figure 3 shows the optical characteristics of a conventional spectacle lens 1 according to the current state of technology, and Figures 4 to 8 are For example, the optical properties of the spectacle lens 1 are shown as in Figures 2a to 2e. The UV-VIS spectra in Figures 4-8 represent the transmittance as a percentage of the wavelength in nanometer units. The dependence, that is, when illuminated using a D65 light source, is known to the wearer through the eyeglass lens. This indicates the transmittance in the visible range, which affects perceived brightness and the color of the observed object.

[0129] Figure 3 shows a clear spectacle lens with no coating (Sample A) for comparison. The UV-VIS absorption spectrum of ) (the spectrum labeled "State A 1") is shown. The sharp drop in transmittance at the "edge," or approximately 400 nm, is due to the presence of the spectacle lens substrate. This is due to UV absorbers. Under UV-VIS illumination, spectral changes do not occur. do not have.

[0130] Furthermore, Figure 3 shows eyeglass lenses based on current technology, i.e., gray Zeiss Photo lenses. Fusion eyeglass lens (Sample B), i.e., a coating that shows a positive photochromic effect. In two different active states (state 1 and state 2) of an eyeglass lens having a coating, The UV-VIS absorption spectrum is shown with increased illumination time in the UV-VIS range. The spectrum labeled "State 1" is in a slightly darkened state, i.e., the UV-VIS range. This corresponds to the UV-VIS absorption spectrum shortly after illumination. It is labeled "B state 2". The spectrum is in a dimmer state, i.e., long after illumination in the UV-VIS range. This corresponds to the UV-VIS absorption spectrum. The "UV edge" at approximately 400 nm is UV absorption of the photochromic composition of the coating and UV absorption contained in the spectacle lens material This is due to absorbing agents. As can be concluded from Figure 3, UV exposure causes absorption P. This leads to a simultaneous increase in the q, meaning that absorption is enhanced throughout almost the entire visible spectral range. This leads to a corresponding decrease in light transmittance.

[0131] Table 1 shows the L of sample B. * a * b * Corresponding L in the color space * a * b * Values ​​and parameters This provides an overview of the light transmittance, abbreviated as "x", "y", and "LTM". Parameter "L * " corresponds to perceived brightness, and parameter "a * " corresponds to the blue-yellow axis, and the parameter " b * This corresponds to the red-green axis. The parameters "x" and "y" are in the CIE1931 color space. These are chromaticity coordinates.

[0132] [Table 1]

[0133] Zeiss PhotoFusion eyeglass lenses (already partially activated) When activated, the light transmittance decreases from 73.59% to 31.03%. VIS range (Co The maximum absorption band in the ting (which includes a mixture of different photochromic materials) is approximately The wavelengths are 580nm and 465nm. When a photochromic material is activated, the transmittance increases. It decreases across the entire IS range. * The parameter value decreases from 88.73 to 62.53 (knowledge) (The perceived luminosity). * The parameter value changes from -1.11 to -0.06, which corresponds to the red color. It accommodates a very slight shift in the target color. * Parameter values ​​range from -0.11 to -7.9 It changes to 6, which corresponds to a clearly perceptible shift in color from yellow to blue.

A simulated spectacle lens 1 (Sample C) having a coating containing the composition 2 shown. The UV-VIS absorption spectrum is shown. Here, the composition exhibits negative photochromicity. 2 is a 1,1'-binaphthyl-crosslinked phenoxyl-imidazo having the following chemical formula (1). It is a lyl radical complex. [ka]

[0135] The transmission spectrum of sample C is from YAMAGUCHI, T. et al. Fast N egative Photochromism of 1,1'-Binaphthyl -Bridged Phenoxyl-Imidazolyl Radical Com Figure from plex, J.Am.Chem.Soc.2016 138(3),906-913 The spectrum was derived by using the left and center of 2a. The disclosed spectrum is 2 mm UV-VIS filter spectrum of uncoated clear eyeglass lenses (Sample A) The transmission spectrum of sample C was obtained by multiplying by the given factor.

[0136] The spectrum labeled "C state 1" represents the inactive state, i.e., illuminated in the UV-VIS range. Corresponds to UV-VIS absorption spectra without activation. Due to negative photochromism. This inactive state corresponds to a "dark" or "yellowish" state.

[0137] The spectrum labeled "C state 2" represents the active state, i.e., the U after illumination in the UV-VIS range. This corresponds to the V-VIS absorption spectrum. This active state is due to negative photochromism. This corresponds to the "colorless" state. The "UV edge" at approximately 400nm is probably the coating. This is caused by UV absorption by the coating and UV absorbers contained in the lens.

[0140] In the active state of sample C, the light transmittance is 89.87%. In the inactive state, the light transmittance is... The rate drops only slightly to 86.25%. This is because the absorption maximum is approximately at 460nm. This is the presence of a prominent absorption band. This is precisely the spectrum that humans perceive as blue. This is the beginning part. * The parameter value is -0.29 in the activated state (approximately shown on the blue-yellow axis).

[0144] The spectrum labeled "D state 2" represents the active state, i.e., the U after illumination in the UV-VIS range. This corresponds to the V-VIS absorption spectrum. This active state is due to negative photochromism. This corresponds to a "bright" or "colorless" state. The "UV edge" at approximately 400 nm is, This is likely caused by the UV absorption of the coating and the UV absorbers contained in the lens.

[0146] [Table 3]

[0147] In the inactive state (state 1), there is a broad absorption maximum from 580 nm to 660 nm. A more clearly defined absorption band is at 480 nm. In the active state (state 2), one absorption The absorption band shifts from approximately 480nm to 500nm. At the same time, the second absorption band shifts to 580nm. The decrease occurs in the range from nm to 660 nm.

[0148] During the transition from the inactive state to the active state, the following occurs: light transmittance changes from 13.76% to 29%. It increased to 0.09%, L * The parameter value also increases from 43.93 to 60.84. * Para The meter value increased from -24.86 to 6.79, which corresponds to a color shift from green to red.

The disclosed spectrum was obtained using 2mm uncoated clear glasses. The UV-VIS filter spectrum of lens (Sample A) is multiplied, and coating I is obtained. The transmission spectrum of spectacle lens I was obtained.

[0152] The transmission spectrum of the spectacle lens with coating II is shown for sample B, i.e., gray. This is the spectrum of a Zeiss PhotoFusion eyeglass lens.

Eyeglass lens 1 is a * and b * This shows extreme changes in parameter values: a * It increased from -10.01 to -0.20 ( (shift towards red), b* It decreases from 26.64 to -1.82 (shift towards blue). This is because the light transmittance of sample E, when activated, is different from that of a normal photochromic lens. This means that it behaves in this way. Therefore, light transmittance decreases when activated. However, transmittance increases in a certain wavelength range, namely 380nm to 470nm, and in another wavelength range... Because the color shift decreases in the range of 470nm to 780nm, the color shift is much larger.
