In the coated lens comprising the lens substrate and the core-shell coating, the outermost surface of the shell of the core-shell coating is relative to the surface of the lens substrate comprising the core-shell coating, the surface facing away from the surface of the lens substrate. In a coated lens comprising only a lens substrate and the core-shell coating, the outermost surface of the shell of the core-shell coating is simultaneously the outermost surface of such a coated lens, i.e., if the coated lens does not comprise an additional coating on top of the core-shell coating, the outermost surface of the shell is the outermost surface of the coated lens. The outermost surface of the shell is the surface of the lens substrate comprising the core-shell coating relative to the surface of the lens substrate, the surface facing away from the lens substrate, but not necessarily the outermost surface of the coated lens. If the coated lens comprises at least one additional coating on top of the core-shell coating (i.e., on top of the surface of the shell facing away from the surface of the lens substrate comprising the core-shell coating), the outermost surface of the shell is not the outermost surface of the coated lens.

The shell of the core-shell coating covers the surface of the core that is not adjacent to the surface of the lens substrate including the core-shell coating.

The core adjacent to and directly adjacent to the surface of the lens substrate preferably adapts to the surface morphology of the surface of the lens substrate. Alternatively, the core of the core-shell coating is adjacent to but not directly adjacent to the surface of the lens substrate including the core-shell coating. In this alternative, at least one additional coating is located between the surface of the lens substrate including the core-shell coating and the core-shell coating itself.

[0291] Preferably, the surface of the core that is not immediately adjacent to the surface of the lens substrate (i.e. the surface of the core that faces away from the surface of the lens substrate comprising the core-shell coating) comprises said stamping.

The geometry of the stamping determines the optimized thickness range of the core. The shell of the core-shell coating provides the necessary protection for the stamping, and more importantly, acts as a bridge layer between the core of the core-shell coating and an adjacent coating (e.g., an anti-reflective coating) in view of the large thermal expansion difference between the core and the adjacent coating.

[0300] In the case where the shell of the core-shell coating is a hard coating as described above, the core-shell coating including a thick core and a thin shell tends to have cracking problems due to different thermal expansions; vice versa, the core-shell coating including a thin core and a thick shell not only limits the ability to implement a stamping portion, but also tends to crack due to the brittleness of the hard coating. Therefore, in order to reduce the risk of cracking, it is preferred that the shell of the core-shell coating has a thickness in the range of 0.6 μm to 10 μm, further preferably 1.5 μm to 8 μm, more preferably 2.0 μm to 7 μm, and most preferably 3 μm to 6 μm.

[0305] (iv) a surface-based fill factor, defined as a surface area ratio of: a surface area of ​​an innermost annular focusing structure among a plurality of annular focusing structures, and a sum of the surface area of ​​the innermost annular focusing structure among the plurality of annular focusing structures and an area of ​​a peripheral clear zone, wherein for a width of the plurality of annular focusing structures in a range of 0.5 mm to 0.6 mm, the surface-based fill factor is in a range of greater than 15% and equal to or less than 60%;

[0306] (v) A surface-based filling factor, defined as the surface area ratio of: a surface area of ​​an innermost annular focusing structure among a plurality of annular focusing structures, and a sum of the surface area of ​​the innermost annular focusing structure among the plurality of annular focusing structures and an area of ​​a peripheral clear zone, wherein for a width of the plurality of annular focusing structures less than 0.5 mm, the surface-based filling factor is in the range of greater than 6% and equal to or less than 50%.

[0307] The definitions and explanations given above regarding "coated lens", "lens substrate", "structure", "annular focusing structure" shall apply.

[0308] The term "width of the annular focusing structure" means the extension of the annular focusing structure along a direction perpendicular to its circumferential direction as measured from the inner and outer starting points of the annular focusing structure. The term "starting point" means the first measurable position of the annular focusing structure on the surface of the coated lens. In other words, the term "starting point" means the position on the surface of the coated lens where the surface shape, form or morphology of the annular focusing structure begins to deviate from the shape, form or morphology of the surface of the coated lens including the annular focusing structure along the width direction; or, assuming that the surface of the coated lens including the annular focusing structure has the same surface shape, form or morphology as the surface of the lens substrate, the term "starting point" means the position on the surface of the coated lens where the surface shape, form or morphology of the annular focusing structure begins to deviate from the shape, form or morphology of the surface of the lens substrate. In addition, the term "inner starting point" specifies the starting point of the annular focusing structure on one side toward the center of the coated lens, and the term "outer starting point" specifies the starting point of the annular focusing structure away from the center of the coated lens toward the periphery.

[0309] In the context of the present invention, the term "clear zone" applies to the structureless area of ​​the coated lens. The clear zone is designed so that when the wearer looks through the clear zone, the clear zone provides neither myopic defocus nor diffuse in foveal vision, provided that the coated lens is positioned according to the specified in-wear position. Furthermore, the clear zone may allow a focused image to be achieved on the fovea with the help of accommodation when necessary.

[0310] The "central clear area" is a structure-free area that is adjacent to and surrounded by the annular focusing structure.

[0311] The optical center of the coated single vision lens (ISO 13666:2019 (E), section 3.2.15) is usually preferably located in the central clear zone. Progressive power coated spectacle lenses may include more than one, in particular two, central clear zones, located, for example, in the near vision portion (ISO 13666:2019, section 3.15.3) and the distance vision portion (ISO 13666:2019, section 3.15.1).

[0312] The "central clear zone width" is the maximum extension of the domain of the central clear zone on the lens surface of the coated lens (i.e., its front or back surface), which is limited by the two inner starting points of the innermost annular focusing structure in opposite tangential directions. Alternatively, the central clear zone width is the maximum extension of the domain of the central clear zone on the lens surface of the coated lens, which is limited by the two inner starting points of the innermost annular focusing structure along each line passing through the optical center or fitting point of the coated lens. The fitting point of the coated lens is defined similarly to ISO 13666:2019(E), section 3.2.34 as the point on the front surface of the coated lens specified by the manufacturer for positioning the coated lens in front of the eye.

[0313] The advantage of a central clear zone with a central clear zone width in the range of 6 mm to 9.4 mm is that a small clear zone (e.g., 6 mm) increases the potential efficacy of the coated lens for slowing down the progression of myopia in a wearer. At the same time, the small clear zone decreases the wearer's acceptance of the coated lens due to the reduced comfort of the wearability of the coated lens. A large clear zone (e.g., 9.4 mm) decreases the potential efficacy of the coated lens for slowing down the progression of myopia in a wearer. At the same time, the large clear zone increases the wearer's acceptance of the coated lens due to the improved comfort of the wearability of the coated lens.

[0314] The term "filling factor" must be subdivided into "length-based filling factor" and "surface-based filling factor." The length-based filling factor is used to determine the filling factor of circular focusing structures, while the surface-based filling factor is used to determine the filling factor of annular focusing structures.

[0315] The length-based fill factor is defined as the ratio of the width of the inner circular focusing structure adjacent to the clear region (“width”) and the radial distance between the inner circular focusing structure and the adjacent circular focusing structures (“pitch”):

[0316]

[0317] The "pitch" is the distance between the starting points of two adjacent circular focusing structures.

[0318] An advantage of a length-based filling factor is that it defines a balance between wearability and manufacturing of the coated lenses of the present invention including circular focusing structures. A length-based filling factor greater than 60% results in a reduction in the comfortable wearability of the coated lens, but increases the potential efficacy of the coated lens for slowing down the progression of myopia in the wearer. A length-based filling factor less than 40% results in a reduction in the potential efficacy of the coated lens for slowing down the progression of myopia in the wearer, but increases the comfortable wearability of the coated lens. In other words, a well-defined balance between wearability and manufacturing of the coated lenses of the present invention is achieved by a length-based filling factor in the range of 40% to 60%. In particular, a length-based filling factor of 50% is preferred.

[0319] The "surface-based fill factor" is determined by the surface area ratio of the innermost annular focusing structure of a plurality of annular focusing structures and the sum of the surface area of ​​the innermost annular focusing structure and the surface area of ​​the peripheral clear zone. The term "innermost" describes the annular focusing structure closest to the central clear zone. The term "peripheral clear zone" refers to the first clear zone close to the central clear zone. In the case where the lens surface of the coated lens (i.e., its front surface and / or back surface) includes one annular focusing structure, the peripheral clear zone is another domain on the corresponding lens surface that does not include one or more annular focusing structures in addition to the central clear zone. The one annular focusing structure separates the central clear zone from the peripheral clear zone. In the case where the lens surface of the coated lens includes the one annular focusing structure, the peripheral zone extends from the outer starting line of the annular focusing structure to the edge of the lens surface. The outer starting line passes along each outer starting point of the one annular focusing structure, and the outer starting line is thereby surrounded or surrounded by the peripheral clear zone. In this context, it should be understood that the inner starting line is the starting line that is preferably closer to the central clear zone, and the outer starting line is preferably further away from the central clear zone.

[0320] In the case where the lens surface of the coated lens (i.e., the front surface or the back surface thereof) includes a plurality of annular focusing structures, the peripheral clear zone is another domain on the corresponding lens surface other than the central clear zone that does not include one or more annular focusing structures. In this case, the peripheral clear zone is another domain that does not include one or more annular focusing structures closest to the central clear zone, and is separated from the central clear zone by the innermost annular focusing structure of the plurality of annular focusing structures. In the case where the lens surface of the coated lens includes the plurality of annular focusing structures, the peripheral clear zone extends from the outer starting line of the innermost annular focusing structure to the inner starting line of the most adjacent annular focusing structure of the plurality of annular focusing structures. The outer starting line passes along each outer starting point of the innermost annular focusing structure and is thereby surrounded by the peripheral clear zone. The inner starting line passes along each inner starting point of the most adjacent annular focusing structure, and the inner starting line thereby limits the expansion of the peripheral zone.

[0321] The surface area of ​​the innermost annular focusing structure is determined by the inner and outer starting lines of the innermost annular focusing structure. The inner starting line passes along each inner starting point of the innermost annular focusing structure, whereby the inner starting line surrounds or surrounds the central clear zone. The outer starting line passes along each outer starting point of the innermost annular focusing structure, whereby the outer starting line is surrounded or surrounded by the peripheral clear zone. The inner and outer starting lines of the innermost annular focusing structure enclose a surface area along the lens surface (i.e., the front surface or the back surface) of the coated lens that is free of one or more structures, which surface area is the surface area of ​​the innermost annular focusing structure.

[0322] In the case where the lens surface of the coated lens (i.e., the front surface and / or the back surface thereof) includes a plurality of annular focusing structures, the surface area of ​​the peripheral clear zone is determined by the outer starting line of the innermost annular focusing structure and the inner starting line of the nearest annular focusing structure, wherein the inner starting line of the nearest annular focusing structure passes along each inner starting point of the nearest annular focusing structure, and the inner starting line thus surrounds or encircles the peripheral clear zone.

[0323] The outer starting line of the innermost annular focusing structure and the inner starting line of at least one adjacent annular focusing structure enclose a surface area along the surface of the coated lens including the multiple annular focusing structures, which surface area is the surface area of ​​the peripheral clear zone.

[0324] An advantage of a surface-based filling factor is that it defines a balance between wearability and manufacturing of a coated lens comprising an annular focusing structure. A surface-based filling factor greater than 59.2% results in a reduction in comfortable wearability of the coated lens, but increases the potential efficacy of the coated lens for slowing myopia progression in a wearer. A surface-based filling factor less than 56.1% results in a reduction in the potential efficacy of the coated lens for slowing myopia progression in a wearer, but increases the comfortable wearability of the coated lens. In other words, a well-defined balance between wearability and manufacturing of the coated lens of the present invention is achieved by a surface-based filling factor in the range of 34.6% to 59.2%. In particular, a surface-based filling factor of 46.4% to 47.7% is preferred.

[0325] Preferably, the stamped portion of the coating is further characterized in that the one or more widths of the at least one annular focusing structure are within at least one range selected from the following group of ranges:

[0326] (i) the width is greater than 0.2 mm and equal to or less than 0.7 mm;

[0327] (ii) the width is greater than 0.3 mm and equal to or less than 0.7 mm;

[0328] (iii) the width is equal to or less than 0.6 mm;

[0329] (iv) the width is greater than 0.2 mm and equal to or less than 0.6 mm;

[0330] (v) the width is greater than 0.3 mm and equal to or less than 0.6 mm;

[0331] (vi) the width is equal to or less than 0.5 mm;

[0332] (vii) the width is greater than 0.2 mm and equal to or less than 0.5 mm;

[0333] (viii) The width is greater than 0.3 mm and equal to or less than 0.5 mm.

[0334] The advantage is a well-defined balance between wearability and manufacturing of the coated lens. A reduction in the width of the annular focusing structure makes the wearability of the coated lens more comfortable. An increase in the width of the annular focusing structure enables easier manufacturing of the coated lens.

[0335] Preferably, the coated lens is further characterized by having a central clear zone width within at least one range selected from the following group of ranges:

[0336] (i) the width of the central clear area is greater than 6 mm and less than or equal to 7 mm;

[0337] (ii) The width of the central clear area is greater than 7 mm and less than or equal to 9.4 mm.

[0338] The advantage of a central clear zone with a central clear zone width in the range of 6 mm to 7 mm is that a small clear zone (e.g., 6 mm) increases the potential efficacy of the coated lens for slowing down the progression of myopia in a wearer. At the same time, the small clear zone may reduce the wearer's acceptance of the coated lens due to reduced comfort of wearability of the coated lens. The advantage of a central clear zone with a central clear zone width in the range of 7 mm to 9.4 mm is that a large clear zone (e.g., 9.4 mm) increases the wearer's acceptance of the coated lens due to improved comfort of wearability of the coated lens.

[0339] Preferably, the coated lens is characterized in that the at least one annular focusing structure provides additional power compared to the central clear zone in at least one range of the following group of ranges:

[0340] (i) the additional power is greater than 6 diopters and equal to or less than 12 diopters;

[0341] (ii) the further power is greater than 7 diopters and equal to or less than 11 diopters;

[0342] (iii) the additional power is greater than 8 diopters and equal to or less than 10 diopters.

[0343] In the context of this specification, the term "additional power" applies to an optical power added to the optical power of a coated lens in at least one meridian, wherein the optical power of the coated lens will provide a focused image on the fovea with the aid of accommodation, and when added to the optical power of the coated lens, the additional power provides myopic through focus. This additional power is not to be confused with the additional power of a progressive multifocal lens.

[0344] The term "optical power" is a collective term for the spherical vertex power of a spectacle lens, which brings a paraxial parallel beam to a single focus and which is usually considered in prescriptions with the "sphere" value or the abbreviation "sph", and the cylindrical vertex power, which brings a paraxial parallel beam to two separate focal lines at right angles to each other (ISO 13666:2019(E), section 3.10.2), and which is usually considered in prescriptions with the "cylinder" value or the abbreviation "cyl").

[0345] An advantage of this further advantageous embodiment is that a balance between wearability and manufacturing of the coated lens is defined. An additional power between 10 diopters and 12 diopters will increase the possible efficacy of the coated lens for slowing down the progression of myopia in the wearer. An additional power between 6 diopters and 8 diopters will increase the comfortable wearability of the coated lens. In other words, a well-defined balance between wearability and manufacturing of the coated lens is achieved by an additional power in the range of 6 diopters to 8 diopters. In particular, an additional power of 10 diopters is preferred.

[0346] The coated lens described above may be available as a physical entity or as a digital twin of the coated lens, the digital twin of the coated lens being available for the purpose of using the digital twin to manufacture the coated lens. The digital twin of the coated lens should be defined similarly as in ISO 13666:2019(E), Section 3.18.1 (Coated lenses) as a digital twin of an eyeglass lens to which one or more surface layers have been digitally added to change one or more properties of the digital twin of the eyeglass lens. The digital twin of the coated lens is available for the purpose of using the digital twin to manufacture the coated lens. The digital twin of the coated lens is a mathematical description of the lens surface of the front surface of the coated lens, a mathematical description of the lens surface of the back surface of the coated lens, the mathematical description including the relative orientation of the lens surface of the front surface relative to the lens surface of the back surface and the refractive index of the digital twin of the lens substrate.

[0347] The digital twin of the coated eyeglass lens for the purpose of use for manufacturing the coated eyeglass lens can be stored on a computer-readable data carrier or converted into a data carrier signal.

[0348] The coated ophthalmic lens according to the present invention may be in the form of computer readable instructions for the production of the coated ophthalmic lens stored on a computer readable data carrier.

[0349] The coated lens designed according to the principles of the present invention described above can also be implemented in the form of computer-readable data stored on a computer-readable data carrier.

[0350] The coated ophthalmic lens according to the present invention may be in the form of computer readable instructions for the production of the coated ophthalmic lens transformed into a data carrier signal.

[0351] The coated mirror designed according to the principles of the present invention described above can also be implemented in the form of a data carrier signal.

[0352] The coated lenses according to the present invention may be in the form of a digital data set.

[0353] The coated lens according to the present invention may be in the form of a data signal that transmits a digital data set.

[0354] The coated ophthalmic lens according to the invention may be in the form of a data carrier storing a digital data set.

[0355] According to the present invention, the method for producing a coated lens comprises at least the following steps:

[0356] - Stamping coating composition.

[0357] The coating composition is a coating composition as described in detail above. The stamped portion, preferably a structure in the form of at least one protrusion and / or at least one recess obtained by stamping the coating composition, has been described above.

[0358] The method for producing a coated lens is characterized by the following steps

[0359] - stamping the coating composition such that the surface power in the domain of the stamping is different from the surface power of the lens surface comprising said coating composition outside said domain of said stamping.

[0360] Compared to WO 2020 / 078964 A1 on which the present invention is based, stamping the coating composition has at least one of the following advantages:

[0361] - No bubbles and curing problems during curing compared to WO 2020 / 078964 A1. All hard coating compositions listed in WO 2020 / 078964 A1 are solvent-based hard coating compositions, and stamping such hard coating compositions leads to problems such as slow curing speed and bubbles due to the inevitable solvent limitation of the laminated lens substrate and stamp,

[0362] - Compared to WO 2020 / 078964 A1, there are no restrictions on the geometry of the stamped structure of the coating composition. Stamped hard coatings have limitations on the compressibility of the hard coating (usually for volume <10%, which means for thickness <3%, CE Weir, Journal of Research of the National Bureau of Standards, Vol. 46, No. 3, March 1951, pp. 207-212; RR Warfield, Compressability of Bulk Polymers, Polymer Engineering and Science, Vol. 6 (2) - April 1, 1966, pp. 176-180),

[0363] - Compared to WO 2020 / 078964 A1, the coating composition is not temporarily stamped. Stamping a hard coating at high temperature and pressure will only be temporary, since the crosslinked coating composition will tend to recover its original shape due to its elastic properties,

[0364] - Compared to WO 2020 / 078964 A1, there is no deformation of the lens substrate even when based on plastic material. Punching the hard coating at high temperature and high pressure would not allow selectively punching the hard coating without deforming the lens substrate based on plastic material.

[0365] - Compared to WO 2020 / 078964 A1, there is no cracking in the coating composition and the resulting coating after curing. Punching under high deformation, high temperature and high pressure, brittle hard coatings lead to cracking of the hard coating.

[0366] Stamping a coating composition shall mean that, compared to US2021 / 0263194 A1, a coating composition has been applied to the lens surface of the lens substrate (i.e., its front surface and / or back surface) and then stamped and transferred to the lens surface via a stamp. As described below, at least one of the coating composition or the coating can be transferred via a stamp to an already existing coating composition on the lens surface of the lens substrate, i.e., to an already existing coating composition on its front surface and / or back surface, while stamping the already existing coating composition. Therefore, compared to US 2021 / 0263194A1, both the transferred coating composition and the already existing coating composition or both the transferred coating and the already existing coating composition include a stamped portion, not just the transferred coating composition or the transferred coating.

[0367] Preferably, the stamping provides a surface power for a lens surface including the stamping (i.e., the front and / or back surface of the coated lens) in the domain of the stamping that is different from the surface power of the lens surface outside the domain of the stamping. Preferably, the difference in surface power is within at least one range selected from the following ranges:

[0368] - the difference in surface power is in the range of greater than 3 diopters and equal to or less than 14 diopters;

[0369] - the difference in surface power is in the range of greater than 5 diopters and equal to or less than 13 diopters;

[0370] - The difference in surface power is in the range of greater than 6 diopters and equal to or less than 12 diopters.

[0371] Preferably, after curing the coating composition to produce the coating, the stamping portion

[0372] Providing the coating with an additional focal power, the additional focal power being within at least one range selected from the following ranges:

[0373] - the additional focal power (ADD) is in the range of greater than 3 diopters and equal to or less than 14 diopters;

[0374] - the additional focal power (ADD) is in the range of greater than 5 diopters and equal to or less than 13 diopters;

[0375] - the additional focal power (ADD) is in the range of greater than 6 diopters and equal to or less than 12 diopters.

[0376] Preferably, in the domain of the stamping, the surface power is different from the surface power of the lens surface comprising a further coating outside said domain of said stamping, the difference in surface power preferably being within at least one range selected from the following ranges:

[0377] - the difference in surface power is in the range of greater than 6 diopters and equal to or less than 12 diopters;

[0378] - the difference in surface power is in the range of greater than 7 diopters and equal to or less than 11 diopters;

[0379] - The difference in surface power is in the range of greater than 8 diopters and equal to or less than 10 diopters.

[0380] Preferably, an additional coating composition is applied to the coating, the additional coating composition being the outermost coating composition and being selected from the group consisting of:

[0381] - a hard coating composition,

[0382] - said coating composition, which preferably has a refractive index difference of at least 0.01 with said coating,

[0383] - the coating composition and a hard coating composition, the hard coating composition being the outermost portion thereof.

[0384] The advantage of applying an additional coating composition (e.g., a hard coating composition that produces a hard coating after curing) is that there is an outermost coating layer for protecting the coating layer, and at least one of the following can be applied to obtain a high quality coated lens:

[0385] - Anti-reflective coating

[0386] -Anti-reflective coating and anti-fog coating, the anti-fog coating is its outermost layer,

[0387] -Anti-reflective coating and a clear coating, the clear coating being the outermost layer thereof.

[0388] Preferably, said further coating is adapted to said coating.

[0389] Preferably, the stamping provides the further coating with a further focal power, the further focal power being within at least one range selected from the following ranges:

[0390] - the additional focal power (ADD) is in the range of greater than 6 diopters and equal to or less than 12 diopters;

[0391] - the additional focal power (ADD) is in the range of greater than 7 diopters and equal to or less than 11 diopters;

[0392] - the additional focal power (ADD) is in the range of greater than 8 diopters and equal to or less than 10 diopters.

[0393] Preferably, the method comprises at least the following steps in a given order:

[0394] (a) applying the coating composition to at least one of:

[0395] - the front surface of the lens substrate,

[0396] - the rear surface of the lens substrate,

[0397] (b) applying the surface of the stamp to at least one of:

[0398] - said front surface comprising said coating composition, and

[0399] - said rear surface comprising said coating composition,

[0400] The coating composition is thereby stamped between at least one of:

[0401] - said front surface and said surface of said stamp, and

[0402] - said rear surface and said surface of said stamp,

[0403] or

[0404] (a') applying a coating composition to the surface of the stamp,

[0405] (b') applying at least one of the front surface of the lens substrate and the back surface of the lens substrate to the surface of the stamp including the coating composition,

[0406] The coating composition is thereby stamped between at least one of:

[0407] - said front surface and said surface of said stamp,

[0408] - said rear surface and said surface of said stamp,

[0409] (c), (c') pre-curing the coating composition to produce a pre-cured coating,

[0410] (d), (d') removing the stamp from the pre-cured coating,

[0411] (e), (e') curing the pre-cured coating to produce a coating, wherein the coating includes a stamped portion.

[0412] The thickness of the coating can be affected by:

[0413] a) Geometry of the stamping part

[0414] b) Viscosity of the coating composition

[0415] c) Total load (weight of impression / lens and additional pressing force) and time

[0416] d) The difference in surface curvature between the lens substrate and the impression.

[0417] The surface area to be covered by the coating composition is affected by:

[0418] a) Volume of coating composition

[0419] b) Total load and time

[0420] c) Viscosity of the coating composition

[0421] d) The base curve of the surface. The steeper the base curve, the more difficult it is to cover a large area.

[0422] From a process perspective, once the stamping geometry is determined, the next step is to define the optimized coating thickness and combine "viscosity", "weight load and time", and "volume of coating composition" to achieve this optimized coating thickness.

[0423] The stamp or at least the surface of the stamp structured or shaped to provide a stamping portion to the adjacent surface of the coating is preferably based on a material with high thermal stability, high UV durability and high transparency. The surface of the stamp should exhibit the characteristics of low water absorption, solvent resistance and low chemical reactivity so that the stamp can be easily removed from the adjacent surface of the aforementioned coating composition. The stamp can be any type of material that can be formed to have a low surface roughness (Ra<1μm), preferably the stamp is an optically transparent plastic.

[0424] The stamp component may be a thermoset or a thermoplastic, for thermosets preferably the stamp is produced by a casting and moulding process, for thermoplastics preferably the stamp is produced by an injection moulding process.

[0425] For the stamping provided, the structure of the stamping may be produced by a casting or injection process of the mould, or separately by further processes, ie laser engraving and single point diamond machining.

[0426] The stamp produced by the above process preferably has no residual chemical functional groups like C=C, -COOH, -OH, -CONH2, -SH, -CO-, -COH, -SO3H, -NH2.

[0427] The stamp preferably has a water absorption in the range of 0% to 0.5%, more preferably in the range of 0% to 0.1%, most preferably in the range of 0% to 0.01%.

[0428] The stamp preferably has a high transmittance in the previously described UV wavelengths, more preferably a transmittance above 50%, most preferably above 80%.

[0429] For example, the structured or shaped stamp, or at least the surface of the stamp, may be based on cyclic block copolymers, such as commercially available as ViviOn (CBC) from USI Corporation.

[0430] According to the present invention, the method for producing a coated lens comprises at least the following steps:

[0431] - stamping the first coating composition, thereby transferring at least one of the second coating composition and the second coating to the first coating composition.

[0432] The method for producing a coated lens is characterized by the following steps:

[0433] - Stamping a first coating composition, thereby transferring a second coating composition and at least one of the second coatings to the first coating composition, such that in the domain of the stamped portion, the surface focal length is different from the surface focal length of the lens surface including the first coating composition and at least one of the second coating composition and the second coating outside the domain of the stamped portion.

[0434] Preferably, the difference in surface power is selected from at least one range in the following group of ranges:

[0435] - the difference in surface power is in the range of greater than 6 diopters and equal to or less than 12 diopters;

[0436] - the difference in surface power is in the range of greater than 7 diopters and equal to or less than 11 diopters;

[0437] - The difference in surface power is in the range of greater than 8 diopters and equal to or less than 10 diopters.

[0438] The method for producing a coated lens is characterized by the following steps:

[0439] - stamping the first coating composition, thereby transferring at least one of the second coating composition and the second coating to the first coating composition, such as the stamping portion comprises an annular structure or a plurality of annular structures.

[0440] The domains, surface powers and annular structures are preferably as described previously.

[0441] With regard to the first coating composition, the explanations given above with regard to the coating composition apply. With regard to the stamping method of the coating composition and the resulting stamped part, the foregoing applies. The second coating is preferably a hard coating.

[0442] Preferably, since in the domain of the stamping, the stamping provides a surface power for the lens surface comprising the second coating, preferably a hard coating (i.e., the front surface and / or the back surface of the coated lens), which surface power is different from the surface power of the lens surface outside the domain of the stamping, the difference in surface power is preferably within at least one range selected from the following ranges:

[0443] - the difference in surface power is in the range of greater than 6 diopters and equal to or less than 12 diopters;

[0444] - the difference in surface power is in the range of greater than 7 diopters and equal to or less than 11 diopters;

[0445] - The difference in surface power is in the range of greater than 8 diopters and equal to or less than 10 diopters.

[0446] As mentioned previously, at least one of the following may further be applied or deposited thereon:

[0464] In the attached picture:

[0465] Figure 1 A coated single vision lens having multiple annular focusing structures in accordance with an embodiment of the present invention is shown.

[0466] Figure 2 Shown according to Figure 1 A cross-sectional view of a coated single vision lens is provided to demonstrate how to determine the width of the annular focusing structure, the pitch of two adjacent annular focusing structures, and the central clear zone width.

[0467] Figure 3 A cross-sectional view of a coated lens according to Example 19 of the present invention is shown, wherein 1 is a lens substrate, 2 is a coating based on a coating composition comprising an epoxy component and an acrylate component, and 3 is a hard coating, an antireflective coating, and a cleaning coating not shown.

[0468] about Figure 1 and Figure 2An exemplary embodiment of the invention is described, and the figures show a coated single vision lens 100. The coated single vision lens 100 comprises a central clear zone 110. In this embodiment, the central clear zone 110 has an optical power designed to correct the wearer's existing myopia. In this exemplary embodiment, the coated single vision lens 100 further comprises five circular focusing structures 101 to 105 of equal cross-section. Circular refers to a ring shape having a circular outline in a front view.

[0469] The circular focusing structures 101 to 105 are formed so that an additional optical power of 12 diopters is provided compared to the optical power of the central clear zone 110. This additional optical power is recognized by the wearer as blur and is demonstrated, for example, in: X. Li, C. Ding, Y. Li, EW: Lim, Y. Gao, B. Fermigier, A. Yang, C. Chen, J. Bao, Influence of Lenslet Configuration on Short-Term Visual Performance in Myopia Control Spectacle Lenses, Front. Neurosci. 2021, 15: 667329, doi: 10.3389 / fnins.2021.667329. This additional optical power slows down the progression of myopia in the wearer.

[0470] Figure 1 and 2 The coated single vision lens 100 shown in has a diameter of 7 cm. Therefore, Figure 1 The coated lens 100 needs to be subjected to an edging process in order to be assembled into a corresponding spectacle frame. The coated single-vision lens 100 includes five circular focusing structures 101 to 105. The circular focusing structures 101 to 105 are arranged concentrically toward the optical center of the coated single-vision lens 100. In addition, the circular focusing structure 101 surrounds a central clear zone 110, and the circular central clear zone width cw110 of the central clear zone is 7.0 mm. The width w101 of the circular focusing structure 101 is 0.5 mm. The adjacent circular structure 102 is arranged concentrically with the inner circular structure 101 surrounding the circular central clear zone 110, wherein the pitch p101 is 1.0 mm. The ratio of the width w101 to the pitch p101 results in a length-based filling factor of 50.0% and a surface-based filling factor of 46.9%.

[0471] Figure 2A cross-sectional view of a coated single vision lens 100 is shown. The front surface 131 of the coated single vision lens 100, which is the outermost surface of the coating, and the front surface 133 of the lens substrate are spherical shapes. Within the scope of the present invention, the shapes of the front surface 131 and the front surface 133 of the coated single vision lens 100 are not limited to spherical shapes, and may also be aspherical, toric, non-toric or even free-form surfaces to meet the individual needs of the wearer.

[0472] Figure 2 It shows how to determine the inner starting point io101 of the circular focusing structure 101 and the outer starting point oo101 of the circular focusing structure 101, the widths w101 to w103 of the circular focusing structure, the pitch p101 of two adjacent circular focusing structures, and the central clear area width cw110. Figure 1 Compared with the five circular focusing structures 101 to 105 shown, Figure 2 Only three circular focusing structures 101 to 103 are shown.

[0473] For the circular focusing structure 101, the determination of the inner starting point and the outer starting point of the circular focusing structure is explained exemplarily. The inner starting point io101 of the circular focusing structure 101 is a point directly adjacent to the central clear area 110. The outer starting point oo101 of the circular focusing structure 101 is a point radially arranged with the inner starting point io101 and directly adjacent to the peripheral clear area 120.

[0474] The width w101 of the circular focusing structure 101 is the radial distance between the inner starting point io101 and the outer starting point oo101. Accordingly, the widths w102 and w103 are determined using the inner starting points io102, io103 and the outer starting points oo102, oo103.

[0475] The pitch p101 of the circular focusing structure 101 is the radial distance between the inner starting point io101 of the circular focusing structure 101 and the inner starting point io102 of the circular focusing structure 102. Accordingly, the pitch w102 is determined using the inner starting points io102 and io103.

[0476] The central clear zone width cw110 of the coated single vision lens 100 is the diameter of the central clear zone 110 .

[0477] according to Figure 1 and 2 The coated single vision lens 100 of the embodiment discloses a central clear zone width cw110, which enables a better acceptance response of the wearer compared to the prior art. In addition, the length-based filling factor lf101 and the pitch p101 are designed to achieve better comfort and acceptance response of the wearer compared to the prior art.

[0478] In summary, the design features and wearer satisfaction of the coated lens 100 having specific characteristics and visual acuity when viewing through the periphery of the lens are as follows:

[0479] - Pitch width: 1mm

[0480] - Cylindrical lens width: 0.5mm

[0481] -ADD focal length: 8D

[0482] - Clear area diameter: 9.4mm

[0483] - Length-based fill factor: 50%

[0484] - Wearer Satisfaction (scale 1-10, study subjects rated the design features on a scale of 1 to 10, where 10 equals the best possible wearability of the coated lens (e.g., a coated single vision lens with a length-based fill factor of 0%) and 1 equals the worst possible wearability of the coated lens (e.g., a coated single vision lens with a length-based fill factor of 100%). A wearability satisfaction score greater than or equal to 4.0 is considered adequate, so that children are likely to accept such lenses with the stated wearability satisfaction score and are likely not inclined to discard such coated lenses): 6.1

[0485] - Visual acuity at 20°: 0.0 log MAR.

[0486] I. Manufacture of coated lenses

[0487] Examples 1 to 6

[0488] A transparent stamp is provided which includes a structure which is made in the form of a recess in the concave surface of the transparent stamp by precision machining. The concave surface of the transparent stamp thus obtained is configured to provide five annular focusing structures to the coating composition. Each annular focusing structure forms a ring of successively connected small lenses on the coating composition. The transparent stamp is made of ViviOn, a cyclic block copolymer of Taiju Corporation. TM 1325. The concave radius of the transparent stamp is 175mm.

[0489] A coating composition comprising 58 g of trimethylolpropane triglycidyl ether, 38 g of pentaerythritol tetraacrylate and 4 g of triarylsulfonium hexafluorophosphate (50% in propylene carbonate) was stirred until homogeneous. The corresponding volume of the coating composition given in the table below was applied to the concave surface of the stamp in the form of drops. The front surface of the corresponding lens substrate given in the table below was placed on the coating composition on the stamp. The radius of the convex front surface of the corresponding lens substrate was 175 mm. A pressing force as given in the table below was applied to the back surface of the corresponding lens substrate, thereby spreading the coating composition to cover the entire convex front surface of the corresponding lens substrate and filling the concave portion in the concave surface of the transparent stamp. After UV pre-curing the coating composition through the stamp with a wavelength of 365 nm for the time and UV dose given in the table below using a LED curing lamp Delolux 20 from Delolux, the stamp was separated from the lens thus coated. The coated lens obtained includes at least one annular focusing structure in the form of a protrusion protruding from the outermost surface of the precured coating composition. The precured coating composition was thermally cured at a temperature of 100° C. for 2 hours.

[0490]

[0491] The coated lens thus obtained is further coated with a primer coating composition by dip coating on the outermost surface of the coating included on the back surface of the lens substrate and on the front surface of the corresponding lens substrate.

[0492] The coated lens thus obtained is further coated with a hard coating composition (e.g. a hard coating composition according to Example 2 of EP 2 578649 A1) by dip coating, and the primer coating composition and the hard coating composition are thermally cured at a temperature of 110° C. for 3 h, thereby producing a primer coating thickness of 0.5 μm each and a hard coating thickness of 2.0 μm each.

[0493] To the coated lens thus obtained, an antireflective coating was deposited under vacuum, resulting in a five-layer stack of SiO2 (30 nm), CrO2 (30 nm), SiO2 (20 nm), CrO2 (60 nm), SiO2 (90 nm), starting from each outermost surface of the hard coating.

[0494] Finally, the coated lens thus obtained was coated on each outermost stack of antireflective coating layers with the clear coating composition Cotec 300+ from COTECH GmbH, resulting in a clear coating with a thickness of 1 nm.

[0495] Examples 7 to 12

[0496] A transparent stamp is provided which includes a structure which is made in the form of a recess in the convex surface of the transparent stamp by precision machining.

The transparent stamp is made of ViviOn, a cyclic block copolymer of Taiju Corporation. TM 1325. The convex radius of the transparent stamp is 175mm.

[0497] DELO PHOTOBOND PS4130, a pressure-sensitive acrylate-based adhesive from DELO, was applied as a coating composition in the form of drops to the concave rear surface of the corresponding lens substrate in the corresponding volume, the volume and the corresponding lens substrate being given in the table below. The radius of the concave rear surface of the corresponding lens substrate was 175 mm. A pressing force as given in the table below was applied to the opposite surface of the transparent stamp, i.e., to the surface of the transparent stamp not including the structure, thereby spreading the coating composition to cover the entire concave rear surface of the corresponding lens substrate. After UV pre-curing the coating composition through the stamp using a LED curing lamp Delolux 20 from DELO with a wavelength of 365 nm for the time and UV dose given in the table below, the stamp was separated from the lens thus coated. The obtained coated lens includes at least one annular focusing structure in the form of a protrusion protruding from the outermost surface of the pre-cured coating composition. The pre-cured coating composition was thermally cured at a temperature of 100° C. for 2 hours.

[0498]

[0499] The coated lens thus obtained is further coated with a primer coating composition by dip coating on the front surface of the lens substrate and on the outermost surface of the coating included on the back surface of the respective lens substrate.

[0500] The coated lens thus obtained is further coated with a hard coating composition (e.g. a hard coating composition according to Example 2 of EP 2 578649 A1) by dip coating, and the primer coating composition and the hard coating composition are thermally cured at a temperature of 110° C. for 3 h, thereby producing a primer coating thickness of 1.5 μm each and a hard coating thickness of 3.0 μm each.

[0501] To the coated lens thus obtained, an antireflective coating was deposited under vacuum, resulting in a five-layer stack of SiO2 (30 nm), CrO2 (30 nm), SiO2 (20 nm), CrO2 (60 nm), SiO2 (90 nm), starting from each outermost surface of the hard coating.

[0502] Finally, the coated lens thus obtained was coated on each outermost stack of antireflective coating layers with the clear coating composition Cotec 300+ from COTECH GmbH, resulting in a clear coating with a thickness of 2 nm.

The applied hard coating composition was pre-cured at a temperature of 60° C. for 10 minutes, thereby producing a pre-cured hard coating with a thickness of 2.7 μm, which thickness does not take into account the filled recesses in the concave surface of the transparent stamp.

[0507] A coating composition comprising 58 g of trimethylolpropane triglycidyl ether, 38 g of pentaerythritol tetraacrylate and 4 g of triarylsulfonium hexafluorophosphate (50% in propylene carbonate) was stirred until uniform. 0.7 ml of the coating composition was applied to the pre-cured hard coating in the form of droplets. The convex front surface of a lens substrate based on 1.60MR-8 (uncut lens) with a convex front surface radius of 175 mm was placed on the coating composition. A pressing force of 400 g was applied to the back surface of the lens substrate, thereby spreading the coating composition to cover the entire surface of the pre-cured hard coating. Using a LED curing lamp Delolux 20 from Delolux, a wavelength of 365 nm was used at 80 s and 10.5 J / cm 2 After UV pre-curing the coating composition with a UV dose of 1000 μg / cm2 through the stamp, the stamp was separated from the lens thus coated. The obtained coated lens included at least one annular focusing structure in the form of a protrusion protruding from the outermost surface of the pre-cured hard coating composition. The pre-cured coating composition was thermally cured at a temperature of 100° C. for 2 hours.

[0546] II Characterization of coated lenses

[0547]

[0548]

[0549] The appearance of the coated lenses according to the Examples and Comparative Examples was determined by visual inspection.

[0550] The adhesion of the coating to the coated lens is evaluated by a cross-cut test. This test applies a pressure-sensitive tape (3M Scotch 600) over two cuts made in the coating and substrate and removes it. The cuts are made by a blade tool with 6 blades mounted in parallel, forming 25 grids measuring 1 mm x 1 mm by vertical cuts. According to the BYK Gardner catalog "QC solutions for coatings and plastics", 2018, page 158, the grading is based on the percentage of the delamination area to the grid area. If the delamination area is greater than 5%, the adhesion is considered unqualified.
