[0002] The present invention is based on WO 2020 / 078964 A1, which discloses an optical article comprising a base lens substrate and an abrasion-resistant coating forming at least one optical element protruding from one of the surfaces of the abrasion-resistant coating. According to paragraph

[063] of WO 2020 / 078964 A1, the abrasion-resistant coating can be prepared from a composition comprising at least one alkoxysilane and / or one of its hydrolysis products, the hydrolysis product being obtained by hydrolysis with a hydrochloric acid solution. According to paragraph

[064] , the abrasion-resistant coating can be based on an epoxysilane hydrolysis product as described in EP 0 614 957 A1, US 4,211,823, and US 5,015,523. EP 0 614 957 A1 discloses the use of methanol or colloidal silica in methanol in the respective compositions used to prepare the abrasion-resistant coating in Examples 1 to 4, Comparative Examples 5, and Examples 6 to 10, and further discloses the use of toluene in Example 11.

[0003] WO 2020 / 078964 A1 describes several methods for manufacturing optical articles, such as molding, additive manufacturing, or thermoforming. Thermoforming can be used when an optical article is to be obtained in which optical elements protrude from a surface away from the base lens substrate. Abrasion-resistant coating is applied to the surface by, for example, dip coating, UV coating, or thermosetting, and then thermoforming involving pressure and temperature is performed. The optical elements can be regularly distributed along a circle centered on the optical center of the refractive region.

The core-shell coating on the rear surface of the lens substrate includes a surface facing away from the rear surface of the lens substrate, and at least the surface of the core-shell coating includes a stamped portion. In the coated lens including 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 including the core-shell coating, and this surface faces 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 also the outermost surface of the coated lens; that is, if the coated lens does not include an additional coating on top of the core-shell coating, then 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 containing the core-shell coating that faces away from the lens substrate, but is not necessarily the outermost surface of the coated lens. If the coated lens includes 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 lens substrate that includes the core-shell coating), then the outermost surface of the shell is not the outermost surface of the coated lens. Preferably, at least the front surface of the lens substrate includes the core-shell coating, which includes a surface facing away from the front surface of the lens substrate, the surface including a stamped portion. More preferably, only the front surface of the lens substrate includes the core-shell coating.

[0289] The surface of the core-shell coating away from the lens substrate, including the surface of the core-shell coating, is preferably shaped or structured to include the stamped portion. Preferably, the shell and the core directly adjacent to the shell are shaped or structured to include the stamped portion.

[0290] The shell of the core-shell coating preferably does not surround the core, but the shell is at least directly adjacent to the surface of the core that faces away from the lens substrate, including the core-shell coating. The shell of the core-shell coating covers the surface of the core that is not immediately adjacent to the surface of the lens substrate, including the core-shell coating. The core of the core-shell coating is immediately adjacent to, and preferably directly adjacent to, the surface of the lens substrate, including the core-shell coating. The core that is immediately adjacent to and directly adjacent to the surface of the lens substrate preferably adapts to the surface morphology of the lens substrate. Alternatively, the core of the core-shell coating is immediately 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, including the core-shell coating) includes the stamped portion. A shell that is immediately adjacent to and directly adjacent to the surface of the core, including the stamped portion, adapts to the surface so as to also include the stamped portion.

[0295] The multiple focal points can be arranged at equal intervals and are preferably mainly linear or point-shaped. The multiple focal points are preferably caused by multiple adjacent small lenses to form a ring of successively connected small lenses.

[0296] The core of the core-shell coating preferably comprises the coating composition as described above.

[0297] The shell of the core-shell coating preferably comprises a hard coating, such as a hard coating as described above.

[0298] The coated lens includes a lens substrate as described above.

[0299] Preferably, the core of the core-shell coating provides a stamped portion, or a recess or protrusion that completely covers the substrate, or both. The geometry of the stamped portion determines the optimized thickness range of the core. The shell of the core-shell coating provides the necessary protection for the stamped portion and, more importantly, acts as a bridge layer between the core and adjacent coatings (e.g., anti-reflective coatings) due to the large difference in thermal expansion between them.

[0300] When 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 expansion; conversely, the core-shell coating, including a thin core and a thick shell, not only limits the ability to form stamped parts, but also tends to crack due to the brittleness of the hard coating. Therefore, in order to reduce the risk of cracking, the shell of the core-shell coating preferably has a thickness in the range of 0.6 μm to 10 μm, more preferably 1.5 μm to 8 μm, more preferably 2.0 μm to 7 μm, and most preferably 3 μm to 6 μm.

[0301] The coated lens according to the invention comprises a coating and / or additional coatings, the coating and / or the additional coatings comprising a stamped portion, the stamped portion comprising at least one annular focusing structure, i.e., one or more annular focusing structures. Preferably, the coated lens comprises a lens substrate as described above, the lens substrate having at least a front surface and a rear surface. The lens substrate comprises at least one coating on at least one of the front surface and the rear surface. The at least one coating on the front surface of the lens substrate comprises a surface facing away from the front surface, at least the surface comprising a stamped portion comprising at least one annular focusing structure. The at least one coating on the rear surface of the lens substrate comprises a surface facing away from the rear surface, at least the surface comprising a stamped portion comprising at least one annular focusing structure.

[0304] (iii) A surface-based fill factor, defined as the surface area ratio of the innermost annular focusing structure among a plurality of annular focusing structures, and the sum of the surface area of ​​the innermost annular focusing structure among the plurality of annular focusing structures and the area of ​​the surrounding clear area, wherein the surface-based fill factor is greater than 17% and equal to or less than 70% for the width of the plurality of annular focusing structures in the range of 0.6 mm to 0.7 mm.

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

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

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

[0308] The term "width of the annular focusing structure" refers to the extension of the annular focusing structure along a direction perpendicular to its circumferential direction, as measured from its inner and outer starting points. The term "starting point" refers to the first measurable location of the annular focusing structure on the surface of the coated lens. In other words, the term "starting point" refers to the location 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 its 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" refers to the location 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. Furthermore, the term "inner starting point" specifies the starting point of the annular focusing structure on the side facing 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 towards the periphery.

[0309] In the context of this invention, the term "zone of clarity" applies to the unstructured area of ​​a coated lens. The zone of clarity is designed such that, when the coated lens is positioned according to a specified wearing position, it neither provides myopic defocus nor diffuses in foveal vision when the wearer views through it. Furthermore, the zone of clarity allows for a focused image to be achieved on the fovea with the aid of accommodation when needed.

[0310] The “central clear area” is an unstructured area that is adjacent to and surrounded by the annular focusing structure.

[0311] The optical center (ISO 13666:2019(E), Section 3.2.15) of a coated single-vision lens is generally preferably located within the central zone of sharpness. Progressive power coated spectacle lenses may include more than one, particularly two, central zones of sharpness 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 central clear zone on the lens surface (i.e., its front or rear surface) of the coated lens, limited by 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 central clear zone on the lens surface of the coated lens, limited by 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 similarly defined in 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 width ranging from 6 mm to 9.4 mm is that a smaller clear zone (e.g., 6 mm) increases the potential effectiveness of the coated lens in slowing myopia progression in the wearer. However, the smaller clear zone also reduces wearer acceptance of the coated lens due to decreased wearability and comfort. Conversely, a larger clear zone (e.g., 9.4 mm) reduces the potential effectiveness of the coated lens in slowing myopia progression in the wearer. However, the larger clear zone increases wearer acceptance of the coated lens due to improved wearability and comfort.

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

[0315] The length-based fill factor is defined as the ratio of the width of the inner circular focus structure adjacent to the area of ​​sharpness (“width”) and the radial distance between the inner circular focus structure and the adjacent circular focus structure (“pitch”):

[0316]

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

[0318] The advantage of a length-based fill factor is that it defines a balance between the wearability and manufacturability of the coated lens of the present invention, including its circular focusing structure. A length-based fill factor greater than 60% results in a decrease in the comfortable wearability of the coated lens but increases its potential efficacy in slowing myopia progression in the wearer. A length-based fill factor less than 40% results in a decrease in the potential efficacy of the coated lens in slowing myopia progression in the wearer but increases its comfortable wearability. In other words, a well-defined balance between the wearability and manufacturability of the coated lens of the present invention is achieved through a length-based fill factor in the range of 40% to 60%. In particular, a length-based fill factor of 50% is preferred.

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

[0320] When the lens surface of a coated lens (i.e., its front or rear surface) includes multiple annular focusing structures, the peripheral zone of sharpness is another region on the corresponding lens surface that does not include one or more annular focusing structures, in addition to the central zone of sharpness. In this case, the peripheral zone of sharpness is another region that does not include one or more annular focusing structures closest to the central zone of sharpness, and is separated from the central zone of sharpness by the innermost annular focusing structure of the multiple annular focusing structures. When the lens surface of the coated lens includes the multiple annular focusing structures, the peripheral zone of sharpness extends from the outer starting line of the innermost annular focusing structure to the inner starting line of the nearest annular focusing structure of the multiple annular focusing structures. The outer starting line passes through each outer starting point of the innermost annular focusing structure and is thus surrounded by the peripheral zone of sharpness. The inner starting line passes through each inner starting point of the nearest annular focusing structure, thereby limiting the extension of the peripheral zone.

[0321] The surface area of ​​the innermost annular focusing structure is determined by its inner and outer starting lines. The inner starting line passes through each inner starting point of the innermost annular focusing structure, thereby surrounding or encircling the central area of ​​focus. The outer starting line passes through each outer starting point of the innermost annular focusing structure, thereby being surrounded or encircling the peripheral area of ​​focus. The inner and outer starting lines of the innermost annular focusing structure enclose the surface area of ​​the coated lens surface (i.e., the front or rear surface) without any one or more structures, which is the surface area of ​​the innermost annular focusing structure.

[0322] In cases where the surface of a coated lens (i.e., its front and / or rear surfaces) comprises multiple annular focusing structures, the surface area of ​​the peripheral clear region is determined by the outer starting line of the innermost annular focusing structure and the inner starting line of the nearest annular focusing structure. The inner starting line of the nearest annular focusing structure passes through each inner starting point of the nearest annular focusing structure, thereby surrounding or encircling the peripheral clear region.

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

[0324] The advantage of surface-based fill factor is that it defines a balance between the wearability and manufacturability of the coated lens, including the annular focusing structure. A surface-based fill factor greater than 59.2% results in reduced wearability comfort of the coated lens but increases its potential efficacy in slowing myopia progression in the wearer. A surface-based fill factor less than 56.1% results in reduced potential efficacy of the coated lens in slowing myopia progression in the wearer but increases its wearability comfort. In other words, the well-defined balance between wearability and manufacturability of the coated lens of the present invention is achieved through a surface-based fill factor in the range of 34.6% to 59.2%. Specifically, a surface-based fill factor of 46.4% to 47.7% is preferred.

[0325] Preferably, the stamped portion of the coating is further characterized in that the width of the at least one annular focusing structure is within at least one range selected from the group consisting of:

[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 lies in the well-defined balance between the wearability of the coated lens and its manufacturing process. The reduced width of the annular focusing structure results in greater comfort and wearability of the coated lens. The increased width of the annular focusing structure makes it easier to manufacture 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 group consisting of:

[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 area with a width in the range of 6mm to 7mm is that a smaller clear area (e.g., 6mm) increases the potential effectiveness of the coated lens in slowing the progression of myopia in the wearer. However, this smaller clear area also reduces wearer acceptance of the coated lens due to decreased wearing comfort. The advantage of a central clear area with a width in the range of 7mm to 9.4mm is that a larger clear area (e.g., 9.4mm) increases wearer acceptance of the coated lens due to improved wearing comfort.

[0339] Preferably, the coated lens is characterized in that, compared to the central area of ​​focus, the at least one annular focusing structure provides additional focal power within at least one range of the following groups:

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

[0341] (ii) The additional diopter is greater than 7 diopters and equal to or less than 11 diopters;

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

[0343] In the context of this specification, the term "additional power" refers to the optical power added to the optical power of a coated lens along at least one meridian, wherein the optical power of the coated lens, with the aid of accommodation, provides a focused image on the fovea, while the additional power, when added to the optical power of the coated lens, provides myopic defocus. This additional power should not be confused with the additional power of a progressive multifocal lens.

[0344] The term "optical power" is a collective term for the spherical power (which brings a paraxial parallel beam to a single focal point and is usually referred to in prescriptions as the "spherical" value or the abbreviation "sph") and the cylindrical power (which brings a paraxial parallel beam to two separate focal lines perpendicular to each other (ISO 13666:2019(E), Section 3.10.2) and is usually referred to in prescriptions as the "cylindrical" value or the abbreviation "cyl").

[0345] This additional advantageous embodiment has the benefit of defining a balance between the wearability and manufacturing of the coated lens. An additional power between 10 and 12 diopters increases the potential effectiveness of the coated lens in slowing the progression of myopia in the wearer. An additional power between 6 and 8 diopters increases the comfortable wearability of the coated lens. In other words, a well-defined balance between the wearability and manufacturing of the coated lens is achieved through an additional power in the range of 6 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 for the purpose of manufacturing the coated lens using the digital twin. The digital twin of the coated lens should be defined similarly to that 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 alter one or more properties of the digital twin of the lens. The digital twin of the coated lens is for the purpose of manufacturing the coated lens using the digital twin. The digital twin of the coated lens is a mathematical description of the lens surface of the front surface of the coated lens and a mathematical description of the lens surface of the rear 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 rear surface and the refractive index of the digital twin of the lens substrate.

[0347] A digital twin of a coated lens for the purpose of manufacturing a coated lens may be stored on a computer-readable data carrier or transformed into a data carrier signal.

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

[0350] The coated lens according to the present invention can be in the form of computer-readable instructions for the production of the coated lens, which are converted into data carrier signals.

[0351] The coated lens 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 lens according to the present invention can be in the form of a digital dataset.

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

[0354] The coated lens according to the present invention can be in the form of a data carrier for storing digital datasets.

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

[0356] - Stamping coating composition.

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

[0358] The method for manufacturing coated lenses is characterized by the following steps:

[0359] - A stamping coating composition, such that the surface focal length in the stamping region is different from the surface focal length of the lens surface including the coating composition outside the stamping region.

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

[0361] - Compared to WO 2020 / 078964 A1, there are no bubbles or curing issues during curing. All hard coating compositions listed in WO 2020 / 078964A1 are solvent-based hard coating compositions. Stamping such hard coating compositions inevitably leads to problems such as slow curing speed and bubbles due to the unavoidable limitations of the solvent on 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 (typically 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; RW Warfield, Compressibility of Bulk Polymers, Polymer Engineering and Science, Vol. 6(2), April 1, 1966, pp. 176-180.

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

[0364] - Compared to WO 2020 / 078964 A1, the lens substrate did not deform even when based on plastic materials. Stamping a hard coating under high temperature and pressure would not allow for selective stamping of the hard coating without deforming the plastic-based lens substrate.

[0365] - Compared to WO 2020 / 078964 A1, no cracking was observed in the coating composition and the resulting cured coating. Under high deformation, high temperature, and high pressure stamping, brittle hard coatings can lead to cracking.

[0366] The term "stamped coating composition" is intended to refer to, as in US 2021 / 0263194 A1, a coating composition that has been applied to the lens surface (i.e., its front and / or rear surfaces) of a lens substrate and then stamped and transferred to the lens surface via a die. As described below, at least one of the coating compositions or coatings can be transferred via a die to an existing coating composition on the lens surface of the lens substrate, i.e., to an existing coating composition on its front and / or rear surfaces, while simultaneously stamping the existing coating composition. Therefore, as in US 2021 / 0263194 A1, both the transferred coating composition and the existing coating composition, or both the transferred coating and the existing coating composition, include a stamping portion, and not just the transferred coating composition or the transferred coating.

[0367] Preferably, the stamping portion provides surface power (i.e., the front and / or rear surfaces of the coated lens) within the domain of the stamping portion to a surface power that differs from the surface power of the lens surface outside the domain of the stamping portion. Preferably, the difference in surface power is within at least one range selected from:

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

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

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

[0371] Preferably, after the coating composition has been cured to produce a coating, the stamping portion...

[0372] The coating is provided with additional focal length, which is selected from at least one of the following ranges:

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

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

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

[0376] Preferably, within the stamping region, the surface power differs from the surface power of a lens surface outside the stamping region, which includes an additional coating, and the difference in surface power is preferably within at least one range selected from:

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

[0378] - The difference in surface diopter is greater than 7 diopters and equal to or less than 11 diopters;

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

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

[0381] - Hard coating composition

[0382] -The coating composition preferably has a refractive index difference of at least 0.01 with the coating.

[0383] -The coating composition and the hard coating composition, wherein the hard coating composition is the outermost layer.

[0384] The advantage of applying an additional coating composition (e.g., a hard coating composition that produces a hard coating upon curing) is that it has an outermost coating to protect the coating, 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, with the anti-fog coating being its outermost layer.

[0387] -Anti-reflective coating and a cleaning coating, which is its outermost layer.

[0388] Preferably, the additional coating is adapted to the coating.

[0389] Preferably, the stamping portion provides additional focal density to the additional coating, the additional focal density being selected from at least one of the following ranges:

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

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

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

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

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

[0395] -The front surface of the lens substrate.

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

[0397] (b) Applying the surface of the impression to at least one of the following:

[0398] - Including the front surface of the coating composition, and

[0399] -The rear surface including the coating composition,

[0400] The coating composition is thus stamped between at least one of the following:

[0401] -The front surface and the surface of the impression, and

[0402] -The rear surface and the surface of the impression.

[0403] or

[0404] (a') Apply the coating composition to the surface of the mold.

[0405] (b') Applying at least one of the front surface and the rear surface of the lens substrate to the surface of the impression comprising the coating composition.

[0406] The coating composition is thus stamped between at least one of the following:

[0407] -The front surface and the surface of the impression.

[0408] -The rear surface and the surface of the impression.

[0409] (c) and (c') pre-cur the coating composition to produce a pre-cured coating.

[0410] (d) and (d') remove the impression from the pre-cured coating.

[0411] (e) and (e') cure the pre-cured coating to produce a coating, the coating including a stamped portion.

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

[0413] a) Geometry of the stamping section

[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 mold.

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

[0418] a) Volume of the coating composition

[0419] b) Total load and time

[0420] c) Viscosity of the coating composition

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

[0422] From a process perspective, once the geometry of the stamping part is determined, the next step is to define an optimized coating thickness, which is achieved by combining factors such as viscosity, weight load and time, and volume of the coating composition.

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

[0424] The mold component can be thermosetting or thermoplastic. For thermosetting, the mold is preferably produced by casting and molding processes, and for thermoplastic, the mold is preferably produced by injection molding processes.

[0425] For the mold providing the stamping portion, the structure of the stamping portion can be produced by casting or injection molding of the mold, or separately by other processes (i.e., laser engraving and single-point diamond machining).

[0426] The impression produced by the above process preferably does not have residual chemical functional groups, such as C=C, -COOH, -OH, -CONH2, -SH, -CO-, -COH, -SO3H, -NH2.

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

[0428] The mold preferably has high transmittance in the previously described UV wavelengths, more preferably higher than 50%, and most preferably higher than 80%.

[0429] For example, the structured or shaped mold, or at least the surface of the mold, can be based on a cyclic block copolymer, such as ViviOn (CBC), which is commercially available from USI Corporation.

[0430] According to the present invention, a method for manufacturing a coated lens includes 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 manufacturing coated lenses is characterized by the following steps:

[0433] - 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 that, in the domain of the stamping portion, the surface power is different from the surface power of the lens surface outside the domain of the stamping portion, which includes the first coating composition and the second coating composition and at least one of the second coating.

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

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

[0436] - The difference in surface diopter is greater than 7 diopters and equal to or less than 11 diopters;

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

[0438] The method for manufacturing coated lenses is characterized by the following steps:

[0439] - Stamping a first coating composition, thereby transferring at least one of a second coating composition and a second coating to the first coating composition, such that the stamping portion includes one or more annular structures.

[0440] The domain, surface foci, and ring structure are preferably as described above.

[0441] Regarding the first coating composition, the foregoing description of the coating composition shall apply. Regarding the stamping method of the coating composition and the resulting stamped portion, the foregoing description shall also apply. The second coating is preferably a hard coating.

[0442] Preferably, since the stamping portion provides surface power to the lens surface (i.e., the front and / or rear surfaces of the coated lens) including the second coating, preferably a hard coating, within the domain of the stamping portion, the surface power differs from the surface power of the lens surface outside the domain of the stamping portion, and the difference in surface power is preferably within at least one range selected from:

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

[0444] - The difference in surface diopter is greater than 7 diopters and equal to or less than 11 diopters;

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

[0446] As mentioned above, at least one of the following may be further applied or deposited on it:

[0447] - Anti-reflective coating

[0448] -Anti-reflective coating and anti-fog coating, with the anti-fog coating being its outermost layer.

[0449] -Anti-reflective coating and a cleaning coating, which is its outermost layer.

[0450] Preferably, the method includes at least the following steps:

[0451] (a) Applying the first coating composition to at least one of the following:

[0452] -The front surface of the lens substrate.

[0453] -The rear surface of the lens substrate,

[0454] (b) Applying an impression comprising another coating to at least one of the following:

[0455] -The front surface including the first coating composition,

[0456] -The rear surface including the first coating composition,

[0457] This process involves stamping the coating composition and transferring the other coating onto the coating composition.

[0458] or

[0459] (a') Applying the first coating composition to the surface of the mold, the surface of the mold comprising another coating.

[0460] (b') Applying at least one of the front surface and the rear surface of the lens substrate to the surface of the impression comprising the second coating composition or the second coating.

[0462] (c)(c') Curing the first and second coating compositions to produce the first and second coatings,

[0463] (d)(d') Remove the mold from the second coating.

[0464] In the attached diagram:

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

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

[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 epoxide component and an acrylate component, and 3 is a hard coating, an anti-reflective coating, and a cleaning coating not shown.

[0468] about Figure 1 and Figure 2Exemplary embodiments of the present invention are described, and these figures illustrate a coated single-vision lens 100. The coated single-vision lens 100 includes a central region of clarity 110. In this embodiment, the central region of clarity 110 has an optical power designed to correct the wearer's existing myopia. In this exemplary embodiment, the coated single-vision lens 100 further includes five circular focusing structures 101 to 105 having equal cross-sections. A circle refers to an annulus having a circular outline in a front view.

[0469] Circular focusing structures 101 to 105 are formed to provide an additional 12 diopters of optical power compared to the optical power of the central clear zone 110. This additional optical power is perceived as blurry by the wearer and has been 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 ControlSpectacle Lenses, Front. Neurosci. 2021, 15:667329, doi:10.3389 / fnins.2021.667329. This additional optical power slows the progression of myopia in the wearer.

[0470] Figure 1 and 2 The coated single-vision lens 100 shown has a diameter of 7 cm. Therefore, Figure 1 The coated lens 100 requires an edge-grinding process for fitting into a corresponding eyeglass frame. The coated single-vision lens 100 includes five circular focusing structures 101 to 105. The circular focusing structures 101 to 105 are arranged co-centered toward the optical center of the coated single-vision lens 100. Furthermore, the circular focusing structure 101 surrounds a central clear region 110, the circular width cw110 of which is 7.0 mm. The width w101 of the circular focusing structure 101 is 0.5 mm. Adjacent circular structures 102 are co-centered with the inner circular structures 101 surrounding the circular central clear region 110, with a pitch p101 of 1.0 mm. The ratio of width w101 to pitch p101 results in a length-based fill factor of 50.0% and a surface-based fill factor of 46.9%.

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

[0472] Figure 2 This demonstrates how to determine the inner starting point io101 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 between two adjacent circular focusing structures, and the width cw110 of the central sharp region. For simplicity, [the text is incomplete and ends abruptly]. Figure 1 Compared to 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 and outer starting points of the circular focusing structure is explained exemplarily. The inner starting point io101 of the circular focusing structure 101 is the point directly adjacent to the central clear area 110. The outer starting point oo101 of the circular focusing structure 101 is the point radially arranged from 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 and io103 and the outer starting points oo102 and 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 width cw110 of the central clear zone 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 provides better reception response for the wearer compared to the prior art. Furthermore, the length-based fill factor lf101 and pitch p101 are designed to achieve better wearer comfort and reception response compared to the prior art.

[0478] In summary, the design features of the coated lens 100 with specific characteristics, wearer satisfaction, and visual acuity when viewed through the peripheral vision of the lens are as follows:

[0479] -Pitch width: 1mm

[0480] - Cylinder width: 0.5mm

[0481] -ADD focal length: 8D

[0482] - Diameter of the clear area: 9.4mm

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

[0484] - Wearer satisfaction (scale 1-10, where participants in the study rated the design feature on a scale of 1 to 10, where 10 equals the best possible wearability of the coated lens (e.g., a length-based fill factor of 0%), and 1 equals the worst possible wearability of the coated lens (e.g., a length-based fill factor of 100%). A wearability satisfaction score greater than or equal to 4.0 was considered sufficient so that children might accept such lenses with the stated wearability satisfaction and might not tend to discard such coated lenses): 6.1

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

[0486] Manufacturing of coated lenses

[0487] Examples 1 to 6

[0488] A transparent mold comprising a structure formed by precision machining into a recess in the concave surface of the transparent mold is provided. The concave surface of the thus obtained transparent mold is configured to provide five annular focusing structures to a coating composition. Each annular focusing structure forms a ring of successively connected small lenses on the coating composition. The transparent mold is made of ViviOn, a cyclic block copolymer from Taiwan Polymer Corporation. TM Made of 1325. The concave radius of the transparent mold is 175mm.

[0489] The 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. Coating compositions of the corresponding volumes given in the table below were applied as droplets to the concave surface of the impression. The front surface of the corresponding lens substrate, as given in the table below, was placed on the coating composition on the impression. 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 rear surface of the corresponding lens substrate, thereby spreading the coating composition to cover the entire convex front surface of the corresponding lens substrate and fill the recesses in the concave surface of the transparent impression. After UV pre-curing of the coating composition through the impression using a Delorlux 20 LED curing lamp at a wavelength of 365 nm with the times and UV doses given in the table below, the impression was separated from the thus coated lens. The resulting coated lens included at least one annular focusing structure in the form of a protrusion extending from the outermost surface of the pre-cured coating composition. The pre-cured coating composition was heat-cured at 100°C for 2 hours.

[0490]

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

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

[0493] In a vacuum, an anti-reflective coating is deposited onto the thus-obtained coated lens, resulting in a five-layer stack, which, starting from the outermost surface of each hard coating, consists of SiO2 (30 nm), CrO2 (30 nm), SiO2 (20 nm), CrO2 (60 nm), and SiO2 (90 nm).

[0494] Finally, the coated lens thus obtained is coated on each outermost stack of the antireflective coating with COTECH GmbH's Cotec 300+ clean coating composition to produce a 1 nm thick clean coating.

[0495] Examples 7 to 12

[0496] A transparent mold comprising a structure formed by precision machining into a recess within a convex surface of the transparent mold. The convex surface of the thus obtained transparent mold is configured to provide at least one annular focusing structure to a coating composition. The transparent mold is made of ViviOn, a cyclic block copolymer from Taiwan Polymer Corporation. TM Made of 1325. The convex radius of the transparent mold is 175mm.

[0497] DELO PHOTOBOND PS4130 pressure-sensitive acrylic adhesive from Delolo was applied as a coating composition in droplet form at a given volume to the recessed surface of the corresponding lens substrate, the volume and the corresponding lens substrate being given in the table below. The radius of the recessed 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 clear impression, i.e., to the surface of the clear impression excluding the structure, thereby spreading the coating composition to cover the entire recessed surface of the corresponding lens substrate. The coating composition was UV pre-cured through the impression using a Delolo LED curing lamp (Delolux 20) at a wavelength of 365 nm for the time and UV dose given in the table below, after which the impression was separated from the thus coated lens. The resulting coated lens included at least one annular focusing structure in the form of a protrusion extending from the outermost surface of the pre-cured coating composition. The pre-cured coating composition was heat-cured at 100°C for 2 hours.

[0498]

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

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

[0501] In a vacuum, an anti-reflective coating is deposited onto the thus-obtained coated lens, resulting in a five-layer stack, which, starting from the outermost surface of each hard coating, consists of SiO2 (30 nm), CrO2 (30 nm), SiO2 (20 nm), CrO2 (60 nm), and SiO2 (90 nm).

[0502] Finally, the coated lens thus obtained is coated on each outermost stack of the antireflective coating with COTECH GmbH's Cotec 300+ clean coating composition to produce a 2nm thick clean coating.

[0503] Examples 13 to 18

[0504] The coated lenses according to Examples 13 to 18 were prepared as the coated lenses according to Examples 1 to 6, except that instead of a primer coating composition and a hard coating composition, only the hard coating composition (e.g., the hard coating composition according to Example 2 of EP 2 578 649A1) was applied to the obtained coated lens by dip coating, that is, applied to the outermost surface of the coating included on the rear surface and the front surface of the respective lens substrate. The hard coating composition was heat-cured at 110°C for 3 hours to produce a hard coating with a thickness of 1.2 μm on the front and rear surfaces of the resulting coated lens.

[0505] Example 19

[0506] The hard coating composition according to Example 2 of EP 2 578 649 A1 was applied by spin coating to the concave surface of the transparent impression provided according to Examples 1 to 6. The applied hard coating composition was pre-cured at 60°C for 10 minutes, thereby producing a pre-cured hard coating with a thickness of 2.7 μm, which does not take into account the filling of the concave portion in the concave surface of the transparent impression.

[0507] The coating composition, comprising 58g trimethylolpropane triglycidyl ether, 38g pentaerythritol tetraacrylate, and 4g triarylsulfonium hexafluorophosphate (50% in propylene carbonate), was stirred until homogeneous. 0.7ml of the coating composition was applied dropwise to the pre-cured hard coating. The front surface of a lens substrate with a front surface radius of 175mm (based on 1.60MR-8 (uncut lens)) was placed on the coating composition. A pressing force of 400g was applied to the rear surface of the lens substrate, thereby spreading the coating composition to cover the entire surface of the pre-cured hard coating. A Deloloux 20 LED curing lamp was used, with a wavelength of 365nm for 80s and 10.5J / cm². 2 After UV pre-curing of the coating composition by means of a UV dose through an imprint, the imprint is separated from the lens thus coated. The resulting coated lens includes at least one annular focusing structure in the form of a protrusion extending from the outermost surface of the pre-cured hard coating composition. The pre-cured coating composition is then heat-cured at 100°C for 2 hours.

[0508] The hard coating composition according to Example 2 of EP 2 578 649 A1 was applied to the rear surface of the lens substrate by spin coating and thermally cured at 110°C for 3 hours, thereby producing a hard coating with a thickness of 3.0 μm.

[0546] Characterization of II-coated lenses

[0547]

[0548]

[0549] The appearance of the coated lens was determined by visual inspection, based on the examples and comparative examples.

[0550] The adhesion between the coating and the coated lens was evaluated using a cross-cut test. This test involves applying pressure-sensitive adhesive tape (3M Scotch 600) to two cuts made in the coating and substrate and then removing it. The cuts were made using a blade tool with six parallel blades, creating 25 1mm x 1mm grids through vertical cutting. Grading was based on the percentage of delamination area relative to the grid area, according to the BYK Gardner catalog "QC solutions for coatings and plastics," 2018, page 158. If the delamination area was greater than 5%, the adhesion was considered unacceptable.
