Description

Technical field

[0001] The present invention relates to a pair of spectacle lenses for reducing myopia progression, the pair of spectacle lenses comprising a first optical lens intended to be worn in front of a wearer's first eye and a second optical lens intended to be worn in front of a wearer's second eye, wherein both the first lens and the second lens have an arrangement of micro-optical elements to induce defocus. The present invention also relates to vision compensation spectacles, the vision compensation spectacles comprising a frame, a first optical lens intended to be worn in front of a wearer's first eye and a second optical lens intended to be worn in front of a wearer's second eye, wherein both the first lens and the second lens have an arrangement of micro-optical elements.

[0002] More precisely, the present invention relates to a pair of spectacle lenses having a specific design to induce a specific defocus or defocusing effect. Background art

[0003] Myopia of the eye is characterized in that the eye focuses light from a distant object in front of the retina. In other words, the eye of a myopic person has a length that is not suitable for clear vision. Myopia has both genetic and environmental causes. In the latter case, its development is due to, for example, an increase in near vision tasks and also due to a decrease in outdoor activities.

[0004] There are many solutions aimed at reducing myopia progression. For example, it is known to use a pair of lenses, each lens being arranged to be worn in front of one eye of a subject and having micro-optical elements configured to induce defocus in the peripheral visual area of the eye while achieving clear vision in the foveal area of the eye. These solutions are practical, but do not distinguish the particularities of the two eyes (such as the dominant eye), so the design of these lenses does not well adapt to the particularities of each eye. In addition, in these solutions, the visual acuity of the subject may change because all the particularities of each eye of the subject are not taken into account. Summary of the invention

[0005] In this context, an object of the present invention is to provide a solution capable of managing myopia progression binocularly, which provides a better compromise between visual acuity and myopia progression control.

[0006] According to the present invention, the above object is achieved by providing a pair of spectacle lenses, the pair of spectacle lenses comprising a first optical lens intended to be worn in front of a wearer's first eye and a second optical lens intended to be worn in front of a wearer's second eye, wherein:

[0007] - The first optical lens includes an arrangement of micro-optical elements, and

[0008] - The second optical lens includes an arrangement of micro-optical elements,

[0009] The arrangement of the micro-optical elements of the first optical lens and the arrangement of the micro-optical elements of the second optical lens are asymmetric with respect to the sagittal plane of the pair of spectacle lenses.

[0010] In other words, the arrangement of the optical elements of the first lens and the arrangement of the optical elements of the second lens present a difference between the symmetric regions of the first lens and the symmetric regions of the second lens, and the symmetric region of the first lens and the symmetric region of the second lens are symmetric with respect to the sagittal plane of the pair of spectacle lenses.

[0011] Due to the optical design of the first lens and the second lens, the pair of spectacle lenses takes into account the particularities of both eyes (such as the dominant eye). Specifically, the design of each eye is adapted to the dominant eye or the non-dominant eye. Therefore, the pair of spectacle lenses presents a good compromise between visual acuity and myopia discomfort and evolution control, and the myopia discomfort and myopia evolution are binocularly managed using the specific optical design of the first lens and the second lens.

[0012] According to an embodiment, the sagittal plane of the pair of spectacle lenses passes at an equal distance between the first lens and the second lens.

[0013] According to an embodiment, the arrangement of the micro-optical elements of the first optical lens differs from the arrangement of the micro-optical elements of the second optical lens in at least one of the following indicators:

[0014] - The density of the micro-optical elements;

[0015] - The diopter of the micro-optical elements;

[0016] - The geometry of the micro-optical elements;

[0017] - The refractive optical function, diffractive optical function or diffusive optical function of the micro-optical elements;

[0018] - The focal length of the micro-optical elements;

[0019] - The diameter of the micro-optical elements;

[0020] - The position of the arrangement of the micro-optical elements in the field of view of the first optical lens and the field of view of the second optical lens;

[0021] - The position of the micro-optical elements in the arrangement of the micro-optical elements.

[0022] According to an embodiment, at least one of the first optical lens and the second optical lens includes a central region having micro-optical elements.

[0023] According to an embodiment, at least one of the first optical lens and the second optical lens includes a central region without any micro-optical elements.

[0024] According to an embodiment, the arrangement of the micro-optical elements of at least one of the first optical lens and the second optical lens includes a plurality of micro-optical element rings having increasing diameters around a central region.

[0025] According to an embodiment, the arrangement of the micro-optical elements of at least one of the first optical lens and the second optical lens includes at least one circular arc centered on the central region.

[0026] According to an embodiment, both the first optical lens and the second optical lens are divided into at least three complementary regions, namely a central region, a first region, and a second region. The arrangement of the micro-optical elements in the first region of the first optical lens is different from the arrangement of the micro-optical elements in the second region of the first optical lens, and the arrangement of the micro-optical elements in the first region of the second optical lens is different from the arrangement of the micro-optical elements in the second region of the second optical lens. The arrangement of the micro-optical elements in the first region of the first optical lens is symmetric with the arrangement of the micro-optical elements in the first region of the second optical lens by rotating 180 degrees about an axis passing through the sagittal plane of the pair of spectacle lenses and perpendicular to the median plane of the pair of spectacle lenses.

[0027] According to another embodiment, both the first optical lens and the second optical lens are divided into five complementary regions, namely a central region and four quadrants at 45 degrees respectively defining a first region, a second region, a third region, and a fourth region. The arrangement of the micro-optical elements in the first region of the first optical lens is different from the arrangements of the micro-optical elements in the second, third, and fourth regions of the first optical lens, and the arrangement of the micro-optical elements in the first region of the second optical lens is different from the arrangements of the micro-optical elements in the second, third, and fourth regions of the second optical lens. The arrangements of the micro-optical elements in the first and second regions of the first optical lens are symmetric with the corresponding arrangements of the micro-optical elements in the first and second regions of the second lens by rotating 180 degrees about an axis passing through the sagittal plane of the pair of spectacle lenses and perpendicular to the median plane of the pair of spectacle lenses.

[0028] Typically, the arrangement of the micro-optical elements in the second region of the first optical lens is different from the arrangements of the micro-optical elements in the third and fourth regions of the first optical lens, and the arrangement of the micro-optical elements in the second region of the second optical lens is different from the arrangements of the micro-optical elements in the third and fourth regions of the second optical lens.

[0029] According to another aspect, the arrangement of the micro-optical elements in the third region of the first optical lens is similar to the arrangement of the micro-optical elements in the fourth region of the first optical lens, and the arrangement of the micro-optical elements in the third region of the second optical lens is similar to the arrangement of the micro-optical elements in the fourth region of the second optical lens.

[0030] Advantageously, the micro-optical elements of at least one of the first optical lens and the second optical lens are contiguous.

[0031] According to another aspect, the arrangement of the micro-optical elements of the optical lens is configured such that both the first optical lens and the second optical lens meet the optical specifications based on the modulation transfer function.

[0032] Advantageously, for example, in different spatial frequency ranges between 1 and 7 cycles per degree and / or between 10 and 20 cycles per degree and / or between 20 and 30 cycles per degree, the optical specifications of the first optical lens are different from those of the second optical lens.

[0033] Advantageously, both the first optical lens and the second optical lens include an optical axis and a horizontal axis and a vertical axis transverse to the optical axis, and at least one of the optical specifications of the first optical lens and the second optical lens exhibits a variation along the horizontal axis and a variation along the vertical axis, and the variation along the vertical axis is different from the variation along the horizontal axis.

[0034] According to a particular and advantageous aspect, the arrangement of the micro-optical elements of at least one of the first optical lens and the second optical lens includes the following: refractive microlenses, diffractive microlenses or diffusive microlenses, π-Fresnel microlenses, microprisms, microdiffusers, microdiffraction gratings, scattering points, Fresnel structures or toric structures.

[0035] According to a particular and advantageous aspect, the arrangement of the micro-optical elements of the first optical lens and the second optical lens is adapted based on the wearer's dominant eye.

[0036] According to a particular and advantageous aspect, at least one of the optical lenses has at least one prescription refractive power in order to provide refractive correction for the wearer's eyes.

[0037] The present invention further relates to vision compensation glasses for managing myopia progression, which vision compensation glasses include a frame and a pair of spectacle lenses as disclosed above. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] In this specification, terms such as "horizontal", "vertical", "above", "below", "front", "rear", "left", "right", etc. or other words indicating relative positions may be used. These terms should be understood under the wearing conditions of the spectacle lens according to the present disclosure.

[0057] Definition

[0058] Figure 12 Is a diagram of the upper half of the first lens 10 and the wearer's first eye or the upper half of the second lens 20 and the wearer's second eye, showing the definitions used in the specification.

[0059] In Figure 12 On, the first lens 10 is positioned in front of the wearer's first eye, or correspondingly, the second lens 20 is positioned in front of the wearer's second eye.

[0060] At least one of the first lens and the second lens has at least one prescription refractive power to provide refractive correction for the corresponding eye of the wearer.

[0061] In the following example, the first lens 10 includes an ophthalmic lens center V10, and correspondingly, the second lens 20 includes an ophthalmic lens center V20. The ophthalmic lens center may be the optical center or the geometric center of the ophthalmic lens. The rear surface of the first lens 10 or the second lens 20 is the surface of the first lens 10 or the second lens 20 closest to the wearer's eye.

[0062] The line segment connecting the ophthalmic lens center V10 of the first lens to the ophthalmic lens center V20 of the second lens 20 is generally equal to the interpupillary distance (IPD).

[0063] The central visual fixation direction is defined by two angles (αC, βC), which represent the eye rotations starting from the primary fixation direction. More precisely, the angle βC and the angle αC represent the horizontal rotation angle and the vertical rotation angle respectively, applied at the eye rotation center ERC in the Fick system to move the eye from the primary fixation reference axis to the eye fixation axis. A third torsion of the eye, derived from these two angles, is applied such that the eye fixation axis complies with Listing's law. Figure 12 Examples of the angles αC and βC with respect to the eye rotation center ERC and the first lens 10 are shown. The central visual fixation direction can be represented by a line passing through the eye rotation center ERC.

[0064] The angle αC is defined in the vertical plane passing through the eye rotation center ERC, while the angle βC is defined in the horizontal plane passing through the eye rotation center ERC. When the wearer's eyes look downwards, the angle αC is defined as positive, and when the wearer's eyes look upwards, the angle αC is defined as negative. When the wearer's eyes look towards the nose side, the angle βC is defined as positive, and when the wearer's eyes look towards the temple side, the angle βC is defined as negative. The rake angle is the angle in the vertical plane between the normal to the rear surface of the first optical lens 10 or the second optical lens 20 and the visual axis (axes z1, z2) of the eye in the primary eye position (which is defined as horizontal when the wearer looks straight ahead at infinity).

[0065] The corneal-to-lens distance is the distance along the visual axis of the eye in the primary eye position between the cornea and the rear surfaces of the first lens 10 and the second lens 20.

[0066] Figure 13 The first lens 10 and the second lens 20 mounted on the frame 70 of the vision compensation glasses are shown. The frame 70 includes temple pieces 71. In this document, the sagittal plane 30 of the glasses is defined as the plane passing at an equal distance from the vertical sides of two rectangular frames, within which the first lens and the second lens are inscribed when mounted in the frame 70. Generally, when the wearer wears the pair of spectacle lenses in front of their eyes, the sagittal plane 30 of the glasses coincides with the sagittal plane of the wearer. The median plane of the pair of spectacle lenses is defined in this document as the plane located at the minimum distance from the rear surfaces of the two lenses 10, 20. We define an axis 50 passing through the sagittal plane 30 of the pair of spectacle lenses and perpendicular to the median plane of the pair of spectacle lenses. The secondary axis 40 of the spectacle lenses is defined in this document as the axis passing through the ophthalmic lens centers V10, V20 of the two lenses 10, 20 and transverse to the sagittal plane 30. Of course, when the first lens 10 and the second lens 20 are mounted on the frame 70, the sagittal plane 30 of the pair of spectacle lenses corresponds to the sagittal plane of the wearer.

[0067] The term "sagittal plane of the wearer" refers to the median plane of a line segment, the ends of which are the centers of rotation of the eyes.

[0068] In the present disclosure, the sagittal plane of the glasses is aligned with the sagittal plane of the wearer.

[0069] The wrap angle of the lens frame 70 is the angle in the horizontal plane between the normal to the rear surface of the first or second lens and the visual axis of the eye in the primary position of gaze.

[0070] The interpupillary distance (denoted as IPD) is the distance between the centers of the pupils of the two eyes of the wearer in the primary position of gaze when the direction of gaze of the eyes does not converge (e.g., when looking at infinity along the horizontal line in the sagittal plane of the wearer (whose head is in an upright position)) (see Figure 13 ).

[0071] In the present application, a micro-optical element refers to various types of micro-optical elements, each of which is made to have a relatively small size, for example, less than 2.5 mm. Micro-optical elements include, for example, lenses, π-Fresnel lenses, prisms, diffusers, beam splitters, or diffraction gratings. The term "micro-optical element" refers to a set of several similar micro-optical elements, including from about ten micro-optical elements to hundreds or thousands of micro-optical elements, depending on their individual size and on various arrangements. Micro-optical elements are typically formed by lithography, holography, molding, machining, or encapsulation.

[0072] Hereinafter, a pair of spectacle lenses is arranged to control myopia progression.

[0073] Device

[0074] In combination Figures 1 to 4 and Figure 11 A first embodiment of a pair of spectacle lenses 100 according to the present disclosure is described.

[0075] Figure 1 The pair of spectacle lenses 100 thereon includes a first optical lens 10 and a second optical lens 20.

[0076] The first optical lens 10 is intended to be disposed in front of the first eye of the wearer, and the second optical lens 20 is a lens intended to be disposed in front of the second eye of the wearer. For example, the first eye refers to the left eye of the wearer, and the second eye refers to the right eye of the wearer.

[0077] Hereinafter, the first optical lens 10 is referred to as the first lens 10, and the second optical lens 20 is referred to as the second lens 20.

[0078] Figure 11An example of the first optical lens 10 or the second optical lens 20 is shown. The first lens 10 or the second lens 20 is a biconvex lens here, but may alternatively be a meniscus lens or a plano-convex lens.

[0079] Figure 11 The first lens 10 or the second lens 20 shown has two opposite optical surfaces, namely the front surface F1 facing the object side and the rear surface F2 closest to the wearer's eye. The first lens 10 or the second lens 20 presents centers V10, V20, which are typically the optical center or the geometric center of the first lens 10 or the second lens 20. In the present disclosure, the first lens 10 is defined as having a first orthogonal reference system (V10, x1, y1, z1), and the second lens 20 is defined as having a second orthogonal reference system (V20, x1, y1, z1), as Figure 1 and Figure 11 shown.

[0080] The first lens 10 has an optical design including a macro-optical component and a micro-optical component.

[0081] The micro-optical component of the optical design (also referred to as the "micro-optical design") of the first lens 10 is made up of a number of micro-optical elements 1 arranged on at least one of the front and rear surfaces (preferably the convex front surface) of the first lens 10.

[0082] The macro-optical component of the optical design (also referred to as the "macro-optical design") of the first lens 10 provides a macro-optical function of providing at least one overall refractive power over most or all of the effective surface area of the first lens 10 to provide refractive correction suitable for the refractive correction needs of the wearer's eyes under wearing conditions. Thus, the macro-optical component of the first lens 10 has at least one predetermined refractive power in order to provide a first refractive correction for the first eye of the wearer. For example, this macro-optical function is provided by the geometry of the front surface F1 or the geometry of the rear surface F2 or the geometries of both surfaces, typically by adapting the radius of curvature of one or both surfaces of the first lens 10. The refractive power of the first lens 10 generally ranges between ±0.25 diopters and ±15 diopters.

[0083] The overall refractive power provided by the macro-optical design of the first lens 10 includes at least the spherical power and / or the cylindrical power and the prism deviation power according to the correction needs of the wearer determined by an eye care professional in order to correct the visual defects of the wearer. Typically, the overall refractive power corresponds to the refractive correction based on the prescription of the wearer (e.g., under standard wearing conditions). For example, the prescription of a refractive error wearer includes the dioptric power values for distance and / or near vision and / or the astigmatic values including the cylinder and axis. Preferably, the overall refractive power of the first lens 10 includes a spherical-compound curve refractive power.

[0084] The term "prescription" shall be understood to mean a set of characteristics determined by an eye care practitioner, having optical power, astigmatism (e.g., of the spherical S, cylindrical C, and axis A type), and / or prism deviation, in order to correct the visual defect of a wearer. For example, the prescription of a refractive error wearer includes optical power values and astigmatism values (S, C, A) for distance and / or near vision.

[0085] The wearing conditions shall be understood as the positions of the first lens 10 and the second lens 20 in the frame 70 worn by the wearer relative to the eyes of the wearer. The wearing conditions are defined hereinafter based on physiological parameters of the wearer when wearing the frame 70 or parameters of the frame 70. For example, the wearing conditions include, for example, the tilt angle, the corneal-to-lens distance, the pupil-to-cornea distance, the distance from the eye rotation center (ERC) to the pupil, and the wrap angle.

[0086] An example of standard wearing conditions can be defined by a tilt angle of -8 degrees for adults or 0° to 5° for children, a corneal-to-lens distance of 12 mm, a pupil-to-cornea distance of 2 mm, a distance from the ERC to the pupil of 11.5 mm, and a wrap angle of 0°.

[0087] Each micro-optical element 1 has its own optical function and has a small size of less than 2 mm, preferably less than 1 mm. Each micro-optical element 1 is constituted, for example, by a microlens, a π-Fresnel lens, a prism, a diffuser, a beam splitter, or a diffraction grating. Micro-optical elements are typically formed by lithography, holography, molding, machining, or encapsulation.

[0088] The micro-optical elements 1 of the first lens 10 form an arrangement 11 of micro-optical elements.

[0089] This arrangement 11 of all the micro-optical elements provides a micro-optical function that is different from and in addition to the macro-optical function of the first lens 10. Thus, the global optical function of the first lens 10 is the sum of its macro-optical function and its micro-optical function provided respectively by the macro-optical component and the micro-optical component of the optical design of the first lens 10. The micro-optical function of the first lens 10 is the optical function provided by the first lens 10 without a macro-optical design (that is, without any overall refractive power over most or all of the effective surface area of the first lens 10). The macro-optical function of the first lens 10 is the optical function provided by the first lens 10 without its micro-optical design (that is, without any micro-optical elements).

[0090] Similarly, the second lens 20 has an optical design including macro-optical components and micro-optical components as described above.

[0091] Preferably, the overall refractive power of the second lens 20 includes spherical-compound surface refractive power.

[0092] The micro-optical elements 1 of the second lens 20 form an arrangement 21 of micro-optical elements.

[0093] Such an arrangement 21 of all the micro-optical elements provides a micro-optical function that is different from and in addition to the macro-optical function of the second lens 20. Thus, the overall optical function of the second lens 20 is the sum of its macro-optical function and its micro-optical function provided respectively by the macro-optical component and the micro-optical component of the optical design of the second lens 20. The micro-optical function of the second lens 20 is the optical function provided by the second lens 20 without a macro-optical design (that is, without any overall refractive power on most or all of the effective surface area of the second lens 20). The macro-optical function of the second lens 20 is the optical function provided by the second lens 20 without its micro-optical design (that is, without any micro-optical elements).

[0094] The arrangement 11 of the micro-optical elements 1 of the first lens 10 has characteristics, and the arrangement 21 of the micro-optical elements of the second lens 20 has characteristics.

[0095] Typically, the arrangement 11 of the micro-optical elements of the first lens 10 and the arrangement 21 of the micro-optical elements of the second lens 20 depend on the following characteristics:

[0096] - The shape of the micro-optical elements;

[0097] - The density of the micro-optical elements or the number or quantity of the micro-optical elements in each optical element arrangement;

[0098] - The diopter of the micro-optical elements;

[0099] - The geometry of the micro-optical elements;

[0100] - The refractive optical function, diffractive optical function or diffusive optical function of the micro-optical elements;

[0101] - The type of the micro-optical elements: refractive microlenses, diffractive microlenses or diffusive microlenses, π-Fresnel microlenses, diffraction gratings, single-focus microlenses, bifocal microlenses, multi-focus microlenses, scattering points, Fresnel structures or toric structures;

[0102] - The focal length of the micro-optical elements;

[0103] - The size or diameter of the micro-optical elements;

[0104] - The position of the arrangement of the micro-optical elements in the field of view of the first lens and the field of view of the second lens;

[0105] - The position of the micro-optical elements in each arrangement of micro-optical elements;

[0106] - The geometric structure or random structure of each arrangement of micro-optical elements.

[0107] To this end, the features described above include the optical features of the micro-optical elements. Typically, the optical features of each micro-optical element include at least one of the following parameters: the diopter of the micro-optical element, the refractive optical function, the diffractive optical function or the diffusive optical function, the focal length, the diameter, the geometry.

[0108] In the present disclosure, each micro-optical element belonging to the arrangement 11 of the first lens 10 or to the arrangement of the second lens 20 has a size between 0.1 mm and 2.5 mm and a surface shape such as, for example, a spherical surface shape or an aspherical surface shape or a toric surface shape.

[0109] Each micro-optical element provides a refractive function, a diffractive function or a diffusive function.

[0110] In an embodiment, some or all of the micro-optical elements of the arrangement 11 of the first lens 10 or of the arrangement 21 of the second lens 20 are refractive micro-optical elements. Each refractive micro-optical element of the arrangement 11 of the first lens 10 or of the arrangement 21 of the second lens 20 may include a single-focus spherical diopter or a bifocal spherical diopter.

[0111] The refractive micro-optical element may be a single-focus micro-optical element or a bifocal micro-optical element.

[0112] For example, the refractive micro-optical element includes a refractive bifocal micro-optical element having a spherical shape or an aspherical shape.

[0113] The diffractive micro-optical element includes, for example, a diffractive π-Fresnel micro-optical element. The diffractive π-Fresnel micro-optical element has a phase function that exhibits a π phase jump at the nominal wavelength λ0. Typically, for human eye vision applications, the wavelength λ0 is considered to be 550 nm. The diffractive Pi Fresnel micro-optical element presents an optical axis perpendicular to its face and passing through the optical center of the micro-optical element. The micro-optical element arrangement having the diffractive π-Fresnel micro-optical element diffracts mainly in two diffractive orders associated with two diopters P0(λ0) and P1(λ0). Thus, when receiving collimated light, the micro-optical element focuses the light on two different regions on its axis. Typically, the diopter P1(λ0) may have a spherical function or an aspherical function for the "+1" diffractive order, and the diopter P0(λ0) may have a spherical function or an aspherical function for the zero diffractive order.

[0114] For example, the diopter P0(λ0) is included in the range of the spherical power of the predetermined refractive power of the first lens or the second lens plus / - 0.12 diopters, which spherical power, for example, originates from the prescription of the wearer.

[0115] According to an embodiment, the absolute value of the diopter P1(λ0) is between 1 diopter and 10 diopters. Preferably, the diopter P1(λ0) is between ±2 diopters and ±6 diopters.

[0116] The diffractive micro-optical element has a diffractive optical function. This means that the diffractive optical element is configured to scatter light. For example, collimated light is scattered in a cone with an apex angle range of + / -1° to + / -40°. In an example, the diffractive micro-optical element is arranged to scatter light locally, i.e., at the intersection between a given micro-optical element and the wavefront arriving at the given micro-optical element. The micro-optical element having a diffractive optical function can be similar to the micro-optical element described in document US10302962.

[0117] In Figure 11 In the example shown, the micro-optical element of the first lens 10 or the second lens 20 is located on the front surface F1 of the first optical lens 10 or the second optical lens 20.

[0118] Alternatively, at least a part or all of the micro-optical elements of the first lens 10 or the second lens 20 are located on the rear surface F2 of the first lens 10 or the second lens 20, or are located on both the front surface F1 and the rear surface F2 of the first lens 10 or the second lens 20 simultaneously.

[0119] Alternatively, all or part of the micro-optical elements of the first lens 10 or the second lens 20 are embedded in the thickness between the front surface and the rear surface of the first lens 10 or the second lens 20.

[0120] Yet alternatively, at least a part or all of the micro-optical elements of the first lens 10 or the second lens 20 are formed on a film, which is in the form of a patch deposited on at least one of the front surface and the rear surface of the first lens 10 or the second lens 20.

[0121] In a variant, at least a part or all of the micro-optical elements are formed by laminating on at least one of the front surface and the rear surface of the first lens 10 or the second lens 20.

[0122] In fact, the micro-optical element and the rest of the first lens 10 or the second lens 20 are formed as a single integral part (typically by injection molding, compression molding, rolling or machining), or alternatively, are formed on a film (formed by patching or lamination) applied on one or both of the front surface F1 and the rear surface F2 of the first lens 10 or the second lens 20.

[0123] Hereinafter, the term "zone" of the lens is relative to the first optical lens or the second optical lens in the same projection plane (i.e., Figures 1 to 10The region defined in the (plane of). Thus, when comparing the region of the first optical lens 10 with the region of the second optical lens 20, the two regions are defined in the same projection plane. The projection plane means the flat plane of the first lens 10 or the second lens 20, regardless of the curvature of the lens under consideration.

[0124] In a non - limiting example, the arrangement 11 of the micro - optical elements of the first lens 10 has the characteristic of providing a first evolution control function for myopia for the first eye of the wearer. Typically, the first evolution control function for myopia is achieved through the micro - optical function of the micro - optical components of the first lens 10. The arrangement 21 of the micro - optical elements of the second lens 20 has the characteristic of providing a second evolution control function for myopia for the second eye of the wearer. Typically, the second evolution control function for myopia is achieved through the micro - optical function of the micro - optical components of the second lens 20. In other words, both the micro - optical elements of the first lens 10 and the micro - optical elements of the second lens 20 have characteristics suitable for controlling the progression of myopia.

[0125] To this end, the arrangement of the micro - optical elements of the first lens 10 is adapted to provide a specific defocus spatial distribution, and the micro - optical elements of the second lens 20 have the characteristic of being adapted to provide another different defocus spatial distribution (also known as the defocus effect). Thus, the arrangement 11 of the micro - optical elements of the first lens 10 has the characteristic of providing a first defocus spatial function, and the arrangement 21 of the micro - optical elements of the second lens 20 has the characteristic of providing a first defocus spatial function. In an exemplary embodiment, the micro - optical elements include microlenses that provide refractive power.

[0126] In a variant, the micro - optical elements provide a diffractive optical function or a diffusive optical function. When the micro - optical elements provide a diffusive optical function, the light entering the wearer's eye is scattered (e.g., unfocused).

[0127] Due to the first evolution control function and the second evolution control function, the light beams (constituted by light rays) passing through the first lens 10 and the second lens 20 respectively are divided into two parts:

[0128] - The first part, which corresponds to the light rays that are deviated by the macro - optical components of a given lens (the first lens 10 or the second lens 20) and are not affected by the arrangement of the micro - optical elements. Typically, the first part corresponds to the light rays that do not pass through one of the micro - optical elements in the arrangement of the micro - optical elements;

[0129] - The second part, which corresponds to the light rays that are affected by the micro - optical components (i.e., the arrangement of the micro - optical elements) and the macro - optical components of a given lens.

[0130] Typically, the second part of the light beam is referred to as the myopia control signal. The myopia control signal can be quantified by the light intensity (hereinafter referred to as the intensity of the myopia control signal).

[0131] The myopia control signal depends on the characteristics of the micro-optical element and is based here on a given evolution control function of myopia (the first evolution control function or the second evolution control function of myopia). Typically, the myopia control signal depends on the refractive optical function, the diffractive optical function, or the diffusive optical function of the micro-optical element. To this end, the myopia control signal is as follows:

[0132] - If the micro-optical element has a diffusive function, it is a diffusive signal. As described above, the diffusive signal corresponds to a non-focused signal, typically a scattered signal;

[0133] - If the micro-optical element has a diffractive function, it is a diffractive signal. As described above, the diffractive signal corresponds to a non-focused signal, typically a scattered signal;

[0134] - If the micro-optical element has a diffusive function (due to the defocusing effect of a given defocus spatial function), it is a refractive signal. The refractive signal corresponds to a focused signal. Typically, in this case, the light entering the wearer's eye is focused in front of the surface of the retina, on a defocus plane located in front of the surface of the retina. In contrast, with respect to the first part of the light beam, the macro-optical function of a given lens providing the prescription refractive power for a given eye focuses the light entering the eye on the surface of the retina of the eye.

[0135] In the Figure 1 example, the first lens 10 includes a central zone 12 bounded by a circular contour 31. In this example, the central zone 12 of the first lens 10 does not have any micro-optical elements and has a circular shape, for example a circular shape with a radius (defined in this example between the ophthalmic lens center V10 of the first lens 10 and the circular contour 31 of the central zone 12) of 4 millimeters.

[0136] The second optical lens 20 includes a central zone 22 bounded by a circular contour 41. In this example, the central zone 22 of the second lens 20 does not have any micro-optical elements and has a circular shape, for example a circular shape with a radius (defined in this example between the ophthalmic lens center V10 of the first lens 10 and the circular contour 41 of the central zone 22) of 4 millimeters.

[0137] The central zones 12, 22 without any optical elements are configured to maximize the visual acuity of the wearer in this zone, since this zone does not include micro-optical elements.

[0138] Of course, in other embodiments, the central region 12 of the first lens 10 and / or the central region of the second lens 20 may have different shapes (e.g., hexagonal shape, or oval shape, or octagonal shape, or triangular shape, or polygonal shape, or asymmetric shape) and different sizes (e.g., a lateral size or diameter between 2 millimeters and 6 millimeters).

[0139] The first lens 10 further includes a first peripheral region 13 disposed around the central region 12 of the first lens 10. The first peripheral region 13 is bounded internally by an inner contour that coincides with the outer contour 31 of the central region 12 and externally by an outer contour 32. In Figure 1 the example of, the arrangement 11 of the micro-optical elements of the first lens 10 is provided on the first peripheral region 13 of the first lens 10.

[0140] The first lens 10 further includes a second peripheral region 18 disposed around the first peripheral region 13. The second peripheral region 18 is bounded internally by an inner contour that coincides with the outer contour 32 of the first peripheral region 13 and externally by an outer contour 33 that coincides with the outer edge 33 of the first lens 10.

[0141] The central region 12, the first peripheral region 13, and the second peripheral region 18 are concentric.

[0142] The second lens 20 further includes a first peripheral region 23 disposed around the central region 22 of the second lens 20. The first peripheral region 23 is bounded internally by an inner contour that coincides with the outer contour 41 of the central region 22 and externally by an outer contour 42. In Figure 1 the example of, the arrangement 21 of the micro-optical elements of the second lens 20 is provided on the first peripheral region 23 of the second lens 20.

[0143] The second lens 20 further includes a second peripheral region 28 disposed around the first peripheral region 23. The second peripheral region 28 is bounded internally by an inner contour that coincides with the outer contour 42 of the first peripheral region 23 and externally by an outer contour 43 that coincides with the outer edge 43 of the second lens 20.

[0144] The central region 22, the first peripheral region 23, and the second peripheral region 28 are concentric.

[0145] The first peripheral region refers to a specific region of the first lens 10 or the second lens 20.

[0146] The second peripheral region refers to a specific region of the first lens 10 or the second lens 20 that is arranged to be fixed to the frame 70 of the spectacle lens. The second peripheral region does not have any optical elements.

[0147] In Figure 1In the example, the first peripheral region 13 of the first lens 10 has the same size as the first peripheral region 23 of the second lens 20.

[0148] In this embodiment, the first peripheral region 13 of the first lens 10 and the first peripheral region 23 of the second lens 20 are symmetric with respect to the sagittal plane 30 of the spectacle lens 100.

[0149] The sagittal plane 30 is perpendicular to the projection plane ( Figure 1 , Figure 7 , Figure 8 and Figure 10 plane). When the first lens 10 and the second lens 20 are mounted on the frame 70 worn by the wearer under standard wearing conditions, the sagittal plane 30 is arranged in the sagittal plane of the wearer. The sagittal plane of the wearer is a physiological plane. The sagittal plane of the wearer corresponds to the vertical median plane of the wearer's head. The sagittal plane of the wearer is a plane orthogonal to the Frankfurt plane passing through the middle of the two rotation centers of the first eye and the second eye (right eye and left eye). Here, the sagittal plane of the wearer is perpendicular to the line segment passing through the rotation centers of the wearer's two eyes and passing through the middle of this line segment. When the wearer holds his head in a straight position, the sagittal plane of the wearer is vertical.

[0150] The arrangement 11 of the micro-optical elements of the first lens 10 (arranged in the first peripheral region 13 of the first lens 10 in this example) is different from the arrangement 21 of the micro-optical elements of the second lens 20 (arranged in the first peripheral region 23 of the second lens 20 in this example).

[0151] More precisely, the arrangement 11 of the micro-optical elements of the first lens 10 and the arrangement 21 of the micro-optical elements of the second lens 20 are not symmetric with respect to the sagittal plane 30 of the spectacle lens 100.

[0152] Asymmetry means that the arrangement of the micro-optical elements of the first lens is different from the arrangement 21 of the micro-optical elements of the second lens 20. This means that the characteristics of the arrangement 11 of the micro-optical elements of the first lens 10 are different from the characteristics of the arrangement 21 of the micro-optical elements of the second lens 20.

[0153] According to the present disclosure, the arrangement 11 of the micro-optical elements of the first lens 10 is different from the arrangement 21 of the micro-optical elements of the second lens 20 in at least one of the following parameters:

[0154] - The shape of the micro-optical elements;

[0155] - The density of the micro-optical elements or the number or quantity of the micro-optical elements in each optical element arrangement;

[0156] - The diopter of the micro-optical elements;

[0157] - Geometric shape of the micro-optical element;

[0158] - Refractive optical function, diffractive optical function or diffusive optical function of the micro-optical element;

[0159] - Type of the micro-optical element: refractive microlens, diffractive microlens or diffusive microlens, π-Fresnel microlens, diffraction grating, bifocal microlens, multifocal microlens, scattering point, Fresnel structure or toric structure;

[0160] - Focal length of the micro-optical element;

[0161] - Size or diameter of the micro-optical element;

[0162] - Position of the micro-optical element in the field of view of the first lens and the field of view of the second lens;

[0163] - Position of the micro-optical element in the arrangement of the micro-optical elements;

[0164] - Position of the micro-optical element in each arrangement of the micro-optical elements;

[0165] - Geometric structure or random structure of each arrangement of the micro-optical elements.

[0166] For example, the micro-optical elements of the first lens 10 and the second lens 20 include micro-optical elements such as microlenses having a disk shape. According to this embodiment, the value of the diameter of the micro-optical element of the first lens 10 is 1 mm, while the value of the diameter of the micro-optical element of the second lens 20 is 2 mm. The value of the optical power of the micro-optical element of the first lens 10 is +2 diopters, while the value of the optical power of the micro-optical element of the second lens 20 is +4 diopters. Additionally, the number of micro-optical elements of the first lens 10 is configured to cover 60% of the surface of the first peripheral region 13 of the first lens 10, while the number of micro-optical elements of the second lens 20 is configured to cover 40% of the surface of the first peripheral region 23 of the second lens 20.

[0167] Preferably, the arrangement of the micro-optical elements of the first lens and the arrangement of the micro-optical elements of the second lens depend on the dominant eye of the wearer. The spectacle lenses according to the present disclosure are designed such that the dominant eye receives fewer myopia control signals via the (as described above) evolution control function than the non-dominant eye to provide maximum visual acuity to the wearer's both eyes. For example, if the dominant eye is the first eye, at least one parameter of the arrangement of the micro-optical elements of the first lens 10 is adapted to provide a lower defocusing effect in the first peripheral region 13 than the defocusing effect provided by the arrangement of the micro-optical elements of the second lens 20 in the first peripheral region 23.

[0168] The dominant eye can be evaluated using methods known to those skilled in the art. For example, the dominant eye can be evaluated using the binocular rivalry paradigm disclosed in the following document: Qiu et al., 2020, "Binocular rivalry from luminance and contrast", Vision Research, https: / / doi.org / 10.1016 / j.visres.2020.06.006.

[0169] Figures 2 to 4 Several examples of various arrangements of the micro-optical elements of the first lens 10 and / or the second lens 20 are shown. It must be understood that Figure 2 the optical design of the shown lens is combined with Figure 3 or Figure 4 the optical design of the presented lens to form the spectacle lens 100. The same applies to Figure 3 and Figure 4 the shown embodiments.

[0170] In Figure 2 each optical element 1 in the micro-optical element arrangement is contiguous with other micro-optical elements in this arrangement. In other words, Figure 2 the micro-optical elements in the shown arrangement are in contact with each other at the edge level of the micro-optical elements.

[0171] This contiguous arrangement of micro-optical elements provides a higher density of micro-optical elements 1 on the first peripheral zone 13 of the first lens 10 or on the second peripheral zone 23 of the second lens 20. High density should be understood as the coverage density, which is defined as the ratio between the total surface of the micro-optical elements and the surface area of the lens or the surface area of the zone including the said arrangement of micro-optical elements. For example, the density of the contiguous micro-optical elements 1 is greater than or equal to 60% or 80% on the surface. In this example, the density of the micro-optical elements on the first peripheral zones 13, 23 is 100%. This means that the micro-optical elements cover the entire area of the first peripheral zones 13, 23.

[0172] In another embodiment, Figure 2 all the micro-optical elements shown are the same. This means that Figure 2 all the micro-optical elements in the shown micro-optical element arrangement exhibit the same parameters. For example, Figure 2 the presented micro-optical elements are spherical microlenses and each has a diameter, for example, between 1 mm and 2 mm and a diopter of +2 diopters. Figure 2 and Figure 15 the micro-optical elements 1 shown are preferably diffractive micro-optical elements or refractive micro-optical elements. In Figure 2 andFigure 15 In the example of, the structure of the arrangement of the micro-optical elements has a hexagonal pattern. Alternatively, the structure of the arrangement may have a square pattern or a rectangular pattern as shown in Figure 16 .

[0173] As Figure 2 shown, the arrangement of the micro-optical elements includes single-focus microlenses or multi-focus microlenses. When the micro-optical elements are single-focus, they may have different surface shapes: spherical, aspherical, or toric.

[0174] Figure 3 Another example of the arrangement of the micro-optical elements is shown. Figure 3 The micro-optical elements shown have a shape similar to that of the micro-optical elements shown in Figure 2 . Additionally, Figure 3 the micro-optical elements shown have a diopter similar to that of the micro-optical elements shown in Figure 2 .

[0175] In Figure 3 the example of, the micro-optical elements are not contiguous. The diameter of each optical element in the arrangement of the micro-optical elements is 1 mm and is spaced apart from the adjacent micro-optical elements by at least 0.1 mm. For example, the edge of one of the optical elements 1 in the arrangement of the micro-optical elements is spaced apart from the edge of the adjacent optical element by 0.5 mm.

[0176] For example, the density of the arrangement of the micro-optical elements in the first peripheral regions 13, 23 is less than 80%, for example, it is 60%.

[0177] With this arrangement of the micro-optical elements, the spacing between adjacent micro-optical elements is adapted to provide a specific defocusing effect. In fact, with this arrangement, Figure 3 the density of the micro-optical elements shown is less than that of the micro-optical elements shown in Figure 2 . This means that the defocusing effect provided by the arrangement of the micro-optical elements in the first peripheral region is less than the defocusing effect provided by the arrangement of the micro-optical elements in Figure 3 . Therefore, the visual acuity provided by the first lens 10 or the second lens 20 with the optical design shown in Figure 2 is different from the visual acuity provided by the optical design provided in the example of Figure 3 . Figure 2

[0178] In the first embodiment, the first lens 10 (preferably the first peripheral region 13 of the first lens 10) includes the arrangement of the micro-optical elements shown in Figure 2 , while the second lens 20 (preferably the first peripheral region 23 of the second lens 20) includes the arrangement of the micro-optical elements shown in Figure 3Arrangement of the micro-optical elements shown. This design of the spectacle lens pair 100 allows each eye to obtain two different types of visual acuity and defocusing effects.

[0179] Figure 4 Another embodiment of the arrangement of the micro-optical elements of the first lens 10 or the second lens 20 is shown.

[0180] In this example, the arrangement of the micro-optical elements includes a plurality of rings of micro-optical elements having an increasing diameter around a central region. In this example, these rings of optical elements are concentric. Each ring of micro-optical elements is, for example, spaced edge-to-edge from an adjacent ring by at least 0.5 mm, for example 2 mm.

[0181] These rings of micro-optical elements are included in the first peripheral region 13 of the first lens 10 or the first peripheral region 23 of the second lens 20.

[0182] Figure 4 The density of the micro-optical elements in the shown arrangement of the micro-optical elements is greater than 30%, preferably 40%, on the first peripheral regions 13, 23 of the first lens 10 or the second lens 20.

[0183] In a non-limiting embodiment, Figure 1 the first lens 10 of Figure 4 includes the arrangement of the micro-optical elements shown, and Figure 1 the second lens 20 of Figure 2 or Figure 3 includes the arrangement of the micro-optical elements of

[0184] Figure 5 Shows Figure 1 the modulation transfer function (MTF) of the first lens in the spectacle lens pair 100 shown, and Figure 6 shows the modulation transfer function of the second lens 20. Such a modulation transfer function enables the evaluation of the defocusing effect caused by the lens having the microlens arrangement, depending on the spatial region of the lens.

[0185] The modulation transfer functions of these examples are for the first lens 10 (for Figure 5 ) or the second lens 20 (for Figure 6) is calculated on a specific zone Zo. To this end, the zone Zo has a circular shape with a diameter between 3 millimeters and 10 millimeters. According to the present disclosure, the specific zone Zo of the first lens 10 or the second lens 20 can be defined over the entire area of the first lens 10 or the second lens 20. The specific zone Zo of the first lens 10 or the second lens 20 includes micro-optical elements. Typically, the density of the micro-optical elements in the zone Zo is higher than 40%. In the following disclosure, the modulation transfer function can be directly measured using an optical system S as described in Figure 14 is described.

[0186] The system S includes a light trapping device C; a light emitting device I configured to generate a collimated beam CB; and an aperture P that is positioned on or very close to the first lens 10 or the second lens 20 and serves as a diaphragm to define the specific zone Zo of the first lens 10 or the second lens 20 (on which the modulation transfer function is measured). Only the light rays in the collimated beam that pass through the aperture P reach the light trapping device. Here, the aperture P is positioned on the front F1 or in front of the first lens 10 or the second lens 20. Of course, in a variant of the system S, the aperture P can be positioned on the back F2 of the first lens 10 or the second lens 20, or behind the back F2 of the first lens 10 or the second lens 20.

[0187] In Figure 14 , the first lens 10 or the second lens 20 is positioned between the light emitting device I and the light trapping device C. The light emitting device I, the aperture P, the first lens 10 or the second lens 20, and the light trapping device C are aligned.

[0188] The light source I is a laser source that emits in a monochromatic visible spectrum or a polychromatic visible spectrum between 400 nm and 780 nm (λ), with a high quality factor M 2 close to 1. Advantageously, the wavelength of the collimated beam emitted by the light source I is between 540 nm and 560 nm, preferably the wavelength is 550 nm.

[0189] The light emitting device I generates a collimated beam CB along an axis A that is clearly perpendicular to the normal plane of the surface of the first lens 10 or the second lens 20 and is centered on the center of the specific zone Zo of the first lens 10 or the second lens 20. As shown in Figure 14 , the collimated beam irradiates the entire area of the specific part Zo of the first lens 10 or the second lens 20.

[0190] In Figure 14 , the first lens 10 or the second lens 20 can be moved along a plane perpendicular to the axis A to select different specific zones Zo of the first lens 10 and the second lens 20, thereby measuring the modulation transfer function on different parts of the first lens 10 and the second lens 20.

[0191] When the first lens 10 or the second lens 20 is irradiated with a collimated beam, the distance between the light-emitting device I and the first lens 10 or the second lens 20 can be varied while substantially not changing the determined modulation transfer function.

[0192] The light-trapping device C includes at least a lens L and an image sensor Sb. The positions of the lens L and the sensor Sb can be adjusted to take into account different analysis planes, for example, by scanning the first lens 10 or the second lens 20 along the axes z1 or z2.

[0193] The sensor Sb is configured to capture an image obtained from the collimated beam generated by the light source I and passing through the first lens 10 or the second lens 20. Based on this captured image, the point spread function (PSF) can be determined, and then the modulation transfer function of the region Zo of the first lens 10 or the second lens 20 can be determined by calculating the Fourier transform of the point spread function.

[0194] In another embodiment, the modulation transfer function of the region Zo of the first lens 10 or the second lens 20 is determined by measuring the surface undulation of the surface of the first lens 10 or the second lens 20 that includes the micro-optical elements (here, the front surface F1 of the considered lens). Typically, the surface undulation of this surface can be determined using an interferometer. The difference in the optical path lengths of two points belonging to the region Zo is determined. For this purpose, the difference in the surface undulations of two different points of the region Zo can be multiplied by a value equal to the refractive index of the given lens (i.e., the refractive index of the macro-optical function). In a variant, the point spread functions in different planes of the given lens can be calculated, and then the modulation transfer function can be calculated.

[0195] In a variant, the simulated modulation transfer function is calculated. In this case, a specific region Zo of the given lens is selected by positioning a simulated aperture P' (i.e., a diaphragm) on the optical design of the first lens 10 or the second lens 20 or by projecting the pupil P' of the eye onto the first lens 10 or the second lens 20. In both cases, the diaphragm P' or the projection is centered on the central visual fixation direction, which is defined by Figure 12 the two angles (αC, βC) shown.

[0196] Regarding the method described above, the simulated modulation transfer function on different specific regions Zo of the first lens 10 or the second lens 20 can be calculated by spatially scanning the field of view of the first lens 10 or the second lens 20 using the simulated aperture P' or the projection P' defined for several central visual fixation directions. This method allows the measurement of the modulation transfer function for different eccentricities of the visual fixation direction.

[0197] Calculate the point spread function (PSF), which gives the degree of spread (blur) of the image of a point object over the entire considered portion Zo of the first lens 10 or the second lens. The point spread function is calculated by simulation known to those skilled in the art, using a point source that emits light in the monochromatic visible spectrum or the polychromatic visible spectrum between 400 nm and 780 nm (λ), typically in the form of an ideal Gaussian (M 2 = 1), centered on the ophthalmic lens centers V10, V20 of the first lens 10 or the second lens 20. For each wavelength λ, the point spread function is calculated as the squared magnitude of the inverse Fourier transform of the aperture function P'(x 1;2 , y 1;2 ), which is defined as P'(x 1;2 , y 1;2 ) = A(x 1;2 , y 1;2 ) exp(ikW(x 1;2 , y 1;2 )) for simulating the simulated aperture P', where k is the wave number (2π / λ), λ is the wavelength of the point source (preferably equal to 550 nm), A(x 1;2 , y 1;2 ) is the apodization function (which can be equal to 1), and W(x 1;2 , y 1;2 ) corresponds to the optical path difference provided by the first lens 10 or the second lens 20. Then, the modulation transfer function is calculated based on the Fourier transform of the calculated point spread function.

[0198] In the examples of Figure 5 and Figure 6 , the modulation transfer function is calculated or measured at a wavelength of 550 nm, through a zone Zo with a diameter of 4 mm, and for a fixation direction (α c , β c ). For the example shown in Figure 5 , this fixation direction exhibits an eccentricity of 6.6 mm relative to the ophthalmic lens center V10 of the first lens 10, or for Figure 6In the example shown, the gaze direction presents an eccentricity of 6.6 millimeters with respect to the ophthalmic lens center V20 of the second lens 20. In the present disclosure, the term "eccentricity" refers to the distance between the ophthalmic lens centers V10, V20 of the lens under consideration and the point on the given lens corresponding to the center of the zone Zo. In another embodiment, when there are no micro-optical elements in the central zones 12, 22 of the first or second lens, the modulation transfer function can be estimated for different eccentricities (e.g., eccentricities between 4 millimeters and 26 millimeters). If the central zones 12, 22 of the first or second lens include micro-optical elements, the modulation transfer function can be further estimated for lower eccentricities (e.g., between 0 millimeters (central gaze direction) and 4 millimeters).

[0199] Figure 5 The horizontal axis curve of the modulation transfer function of the first lens 10 and the vertical axis curve of the modulation transfer function of the first lens 10 are shown.

[0200] In this example, the first lens 10 has contiguous micro-optical elements, as Figure 2 shown. In this embodiment, the micro-optical elements can be, for example, π-Fresnel micro-optical elements with a diameter of 2 millimeters and a diopter between 0 diopters and 10 diopters. Preferably, in this example, the π-Fresnel micro-optical elements of the first lens 10 have a diopter P0(λ0) equal to 0 diopters and a diopter P1(λ0) equal to 4 diopters.

[0201] In the present disclosure, the horizontal axis curve of the modulation transfer function corresponds to the variation of the modulation transfer function estimated or calculated along the horizontal axis x1 of the first lens 10 or correspondingly along the horizontal axis x2 of the second lens 20. Hereinafter, this curve is referred to as the horizontal modulation transfer function. The horizontal modulation transfer function corresponds to a cross-section of the Fourier transform of the point spread function along the horizontal axis x1 of the first lens 10 or correspondingly along the horizontal axis x2 of the second lens 20. In contrast, the vertical axis curve of the modulation transfer function corresponds to the variation of the modulation transfer function calculated or estimated along the vertical axis y1 of the first lens 10 or correspondingly along the vertical axis y2 of the second lens 20. Hereinafter, this curve is referred to as the vertical modulation transfer function. The vertical modulation transfer function corresponds to a cross-section of the Fourier transform of the point spread function along the vertical axis y1 of the first lens 10 or correspondingly along the vertical axis y2 of the second lens 20.

[0202] At Figure 5 this point, the vertical modulation transfer function and the horizontal transfer function follow the same variation and they are superimposed on each other. This means that the optical design of the first lens 10 provides the same optical function along the vertical axis y1 and along the horizontal axis x1. Therefore, for Figure 5In the example shown, the present disclosure uses only the term "modulation transfer function" when referring to the vertical modulation transfer function and the horizontal modulation transfer function.

[0203] According to this embodiment, the modulation transfer function exhibits values greater than or equal to 0.60, 0.65, 0.70, 0.75, 0.80, 0.85, 0.90, 0.95 (a.u.) in a spatial frequency range between 0 and 7 cycles per degree, preferably between 0 and 5 cycles per degree.

[0204] In Figure 5 Regarding the first lens 10, the modulation transfer function at a spatial frequency of 5 cycles per degree is less than or equal to 0.4, preferably less than 0.35. According to this example, the modulation transfer function reaches a minimum value of 51 (a.u.) within a spatial frequency range between 3 and 5 cycles per degree.

[0205] The modulation transfer function exhibits values less than or equal to 0.50, 0.45, 0.40, 0.35 (a.u.) in a spatial frequency range between 2 and 7 cycles per degree.

[0206] In addition, the modulation transfer function of the first lens 10 exhibits attenuation at a spatial frequency between 4 and 5 cycles per degree. Then, for spatial frequencies between 6 and 12 cycles per degree, the modulation transfer function of the first lens 10 exhibits values greater than 0.4, preferably greater than 0.35. Therefore, the modulation transfer function exhibits a peak 52 in a spatial frequency range between 6 and 11 cycles per degree. For this spatial frequency range, for a spatial frequency equal to 9 cycles per degree, the modulation transfer function reaches a maximum value of 53. Then, for spatial frequencies greater than 9 cycles per degree, Figure 5 the modulation transfer function on

[0207] The modulation transfer function exhibits values greater than or equal to 0.30, 0.35, 0.40, 0.41 in a spatial frequency range between 6 and 12 cycles per degree.

[0208] For intermediate spatial frequencies, specifically for spatial frequencies between 5 and 10 cycles per degree, the first lens 10 provides good visual performance.

[0209] Figure 6 The horizontal axis curve 63 of the modulation transfer function of the second lens 20 and the vertical axis curve 64 of the modulation transfer function of the second lens 20 are shown.

[0210] The second lens 20 of the embodiment of the spectacle lens 100 includes, for example, as Figure 10The arrangement of the micro-optical elements shown, the characteristics (parameters) presented by this arrangement vary depending on each of the four quadrants at 45 degrees. In this embodiment, the micro-optical element is a single-focus contiguous micro-optical element with a diameter of 0.6 mm and a diopter between 3.5 diopters and 6 diopters.

[0211] In this example, the horizontal axis curve 63 of the modulation transfer function of the second lens 20 and the vertical axis curve 64 of the modulation transfer function of the second lens 20 are estimated or calculated using an aperture P', P with a diameter of 4 mm and for a fixation direction (α c , β c ) presenting an eccentricity of 6.6 mm (relative to the ophthalmic lens center V20 of the second lens 20).

[0212] In Figure 6 's example, the vertical modulation transfer function and the horizontal transfer function do not follow the same variation. This means that the optical design of the second lens 20 provides different optical functions along the vertical axis y2 and along the horizontal axis x2.

[0213] In Figure 6 's case, the horizontal modulation transfer function 63 presents multiple peaks and multiple valleys. Specifically, Figure 6 's horizontal modulation transfer function 63 reaches:

[0214] - A maximum value 65a, which has a value greater than 0.9 at a spatial frequency of 0 cycles per degree;

[0215] - A maximum value 65b, which has a value between 0.85 and 0.75 for a spatial frequency between 18 and 21 cycles per degree;

[0216] - A maximum value 65c, which has a value between 0.65 and 0.55 for a spatial frequency between 35 and 42 cycles per degree;

[0217] - A maximum value 65d, which has a value between 0.50 and 0.40 for a spatial frequency between 54 and 57 cycles per degree.

[0218] The horizontal modulation transfer function 63 exhibits values greater than or equal to 0.33 in the spatial frequency range between 18 and 21 cycles per degree, values greater than or equal to 0.3 in the spatial frequency range between 35 and 42 cycles per degree, and values greater than or equal to 0.2 in the spatial frequency range between 54 and 57 cycles per degree. Preferably, the maximum value 65 of the horizontal transfer function 63 is greater than or equal to 0.6 in the spatial frequency range between 18 and 21 cycles per degree, the maximum value 65 of the horizontal transfer function 63 is greater than or equal to 0.5 in the spatial frequency range between 35 and 42 cycles per degree, and the maximum value 65 of the horizontal transfer function 63 is greater than or equal to 0.35 in the spatial frequency range between 54 and 57 cycles per degree.

[0219] The horizontal modulation transfer function 63 exhibits values greater than or equal to 0.60, 0.65, 0.70, 0.75, 0.80, 0.85, 0.90, 0.95 in the spatial frequency range between 0 and 7 cycles per degree, preferably between 0 and 5 cycles per degree.

[0220] The horizontal modulation transfer function exhibits values greater than or equal to 0.60, 0.65, 0.70, 0.75, 0.80 in the spatial frequency range between 15 and 23 cycles per degree. Additionally, according to this embodiment, the horizontal modulation transfer function 63 exhibits values greater than or equal to 0.40, 0.45, 0.50, 0.55, 0.60 in the spatial frequency range between 33 and 43 cycles per degree. Then, the horizontal modulation transfer function 63 exhibits values greater than or equal to 0.30, 0.35, 0.40, 0.42 in the spatial frequency range between 53 and 57 cycles per degree.

[0221] Additionally, in Figure 6 the example of, the horizontal modulation transfer function 63 attenuates around 10 cycles per degree, 28 cycles per degree, and 47 cycles per degree. Preferably, Figure 6 the horizontal modulation transfer function 63 of reaches:

[0222] - a minimum value 67a, which has a value between 0.40 and 0.30 for the spatial frequency between 8 and 12 cycles per degree;

[0223] - a minimum value 67b, which has a value between 0.30 and 0.20 for the spatial frequency between 25 and 32 cycles per degree;

[0224] - a minimum value 67c, which has a value between 0.25 and 0.15 for the spatial frequency between 41 and 52 cycles per degree.

[0225] The horizontal modulation transfer function 63 exhibits values less than or equal to 0.5, preferably less than or equal to 0.4, in the spatial frequency range between 8 and 12 cycles per degree, values less than or equal to 0.35 in the spatial frequency range between 25 and 32 cycles per degree, and values less than or equal to 0.3, preferably less than or equal to 0.26, in the spatial frequency range between 41 and 52 cycles per degree. Preferably, the minimum value 67 of the horizontal transfer function 63 is less than or equal to 0.35 in the spatial frequency range between 8 and 12 cycles per degree, the minimum value 67 of the horizontal transfer function 63 is less than or equal to 0.28 in the spatial frequency range between 25 and 32 cycles per degree, and the minimum value 67 of the horizontal transfer function 63 is less than or equal to 0.24 in the spatial frequency range between 41 and 52 cycles per degree.

[0226] According to this embodiment of the present disclosure, the horizontal modulation transfer function 63 exhibits values less than or equal to 0.50, 0.45, 0.40, 0.35 in the spatial frequency range between 6 and 12 cycles per degree, preferably between 8 and 12 cycles per degree. Additionally, the horizontal modulation transfer function 63 exhibits values less than or equal to 0.45, 0.40, 0.35, 0.30, 0.28 in the spatial frequency range between 25 and 35 cycles per degree, preferably between 25 and 32 cycles per degree. Then, the horizontal modulation transfer function 63 exhibits values less than or equal to 0.40, 0.35, 0.30, 0.25, 0.23, 0.20 in the spatial frequency range between 41 and 54 cycles per degree, preferably between 45 and 52 cycles per degree.

[0227] On Figure 6 the vertical modulation transfer function 64 exhibits a peak and multiple valleys. Specifically, Figure 6 the vertical modulation transfer function 64 of

[0228] According to this embodiment, the vertical modulation transfer function 64 exhibits values greater than or equal to 0.60, 0.65, 0.70, 0.75, 0.80, 0.85, 0.90, 0.95 in the spatial frequency range between 0 and 7 cycles per degree, preferably between 0 and 5 cycles per degree.

[0229] According to this embodiment, the vertical modulation transfer function 64 exhibits values greater than or equal to 0.40, 0.45, 0.50, 0.55, 0.60, 0.63, 0.65 in the spatial frequency range between 28 and 38 cycles per degree, preferably between 30 and 35 cycles per degree.

[0230] Additionally, on Figure 6In the example, the vertical modulation transfer function 64 decays between 10 and 26 cycles per degree and between 40 and 60 cycles per degree. Preferably, Figure 6 the vertical modulation transfer function 64 reaches:

[0231] - a minimum value 68a, which has a value between 0.35 and 0.25 for spatial frequencies between 10 and 28 cycles per degree;

[0232] - a minimum value 68b, which has a value between 0.25 and 0.15 for spatial frequencies between 40 and 60 cycles per degree.

[0233] According to this example, the vertical modulation transfer function 64 exhibits a value less than or equal to 0.33 in the spatial frequency range between 10 and 26 cycles per degree, and exhibits a value less than or equal to 0.3 in the spatial frequency range between 10 and 26 cycles per degree.

[0234] In this embodiment, the vertical modulation transfer function 64 exhibits values less than or equal to 0.45, 0.40, 0.35, 0.34, 0.33, 0.32 in the spatial frequency range between 6 and 28 cycles per degree, preferably between 10 and 16 cycles per degree. Then, the vertical modulation transfer function 64 exhibits values less than or equal to 0.35, 0.30, 0.25, 0.20, 0.19, 0.18 in the spatial frequency range between 37 and 60 cycles per degree, preferably between 40 and 60 cycles per degree.

[0235] The second lens 20 exhibits a vertical modulation transfer function, and the vertical modulation transfer function has multiple peaks and multiple valleys. This design provides good visual performance for high spatial frequencies, specifically for frequencies between 20 and 30 cycles per degree.

[0236] For the pair of spectacle lenses 100 according to the present disclosure, the vertical modulation transfer function of the first lens 10 is different from that of the second lens 20. Additionally, the horizontal modulation transfer function of the first lens 10 is different from that of the second lens 20. Thus, the first lens 10 exhibits good optical performance for a specific frequency range, and the second lens 20 exhibits good optical performance for other specific frequency ranges.

[0237] According to this embodiment, the curves of the modulation transfer functions of the first lens 10 and the second lens 20 can be adapted to the dominant eye of the wearer.

[0238] For example, if the wearer's second eye is the dominant eye and the wearer needs a pair of spectacle lenses for reading small print, the optical design of the second lens 20 (due to the characteristics of the micro-optical elements) is selected to provide a high modulation transfer function (i.e., greater than 0.4, preferably greater than 0.5) in the spatial frequency range between 20 and 30 cycles per degree, and a low modulation transfer function in the spatial frequency range between 5 and 10 cycles per degree. In contrast, the optical design of the first lens 10 is selected to provide a high modulation transfer function in the spatial frequency range between 5 and 10 cycles per degree, and a low modulation transfer function in the spatial frequency range between 20 and 30 cycles per degree. Thus, the second lens 20 provides a different defocus effect from the first lens 10.

[0239] Combined Figures 2 to 4 and Figure 7 describes a second embodiment of a pair of spectacle lenses 200 according to the present disclosure.

[0240] Figure 7 Shows a pair of spectacle lenses 200 having a first lens 10 and a second lens 20. The second lens 20 in this pair of spectacle lenses 200 is the same as the second lens 20 included in the pair of spectacle lenses 100. Therefore, only the differences from Figure 1 this pair of spectacle lenses 100 will be described.

[0241] In this embodiment, the central region 12 of the first lens 10 includes micro-optical elements 1. Thus, the arrangement 11 of the micro-optical elements of the first lens 10 extends over the central region 12 of the first lens 10. This embodiment allows for obtaining a first lens 10 that is completely covered by the micro-optical element arrangement. The first lens 10 does not contain any regions without micro-optical elements. Therefore, the arrangement of the micro-optical elements in the second region 15 of the first lens 10 and the arrangement of the micro-optical elements in the second region 25 of the second lens 20 are asymmetric with respect to the sagittal plane 30 of the pair of spectacle lenses.

[0242] Preferably, the micro-optical elements 1 arranged in the central region 11 of the first lens 10 have an arrangement similar to that of the micro-optical elements 1 arranged on the first peripheral region 13 of the first lens 10. This means that the micro-optical elements of the first lens 10 have a similar pattern on the central region 12 and the first peripheral region 13. This optical design provides a first lens 10 that is easy to manufacture, thereby limiting the cost of the pair of spectacle lenses 200. This optical design is meaningful, for example, because in the case of astigmatism correction, the manufacturing process of the first lens 10 does not need to consider the cylinder axis position, thereby improving the time and ease of the manufacturing process.

[0243] Combined Figures 8 to 9 describes a third embodiment of a pair of spectacle lenses 300 according to the present disclosure.

[0244] In this embodiment, the first lens 10 and the second lens 20 include central regions 12, 22. The central region 12 of the first lens 10 does not have any micro-optical elements, and the central region 22 of the second lens 20 does not have any micro-optical elements.

[0245] In this embodiment, both the first lens 10 and the second lens 20 are divided into at least three complementary regions, namely central regions 12, 22, first regions 14, 24, and second regions 15, 25. The first region 14 and the second region 15 of the first lens 10 constitute the first peripheral region 13 of the first lens 10, and correspondingly, the first region 24 and the second region 25 of the second lens 20 constitute the first peripheral region 23 of the second lens 20.

[0246] The first region 14 of the first lens 10 is disposed above the secondary axis 40, and the first region 24 of the second lens 20 is disposed below the secondary axis 40, and correspondingly, the second region 15 of the first lens 10 is disposed below the secondary axis 40, and the second region 25 of the second lens 20 is disposed above the secondary axis 40. Of course, in a variant, the first region 14 of the first lens 10 may be disposed below the secondary axis 40, and the first region 24 of the second lens 20 may be disposed above the secondary axis 40, and correspondingly, the second region 15 of the first lens 10 may be disposed above the secondary axis 40, and the second region 25 of the second lens 20 may be disposed below the secondary axis 40.

[0247] In a preferred embodiment, the first region 14 of the first lens 10 is the same as the first region 24 of the second lens 20, and correspondingly, the second region 15 of the first lens 10 is the same as the second region 25 of the second lens 20. For this purpose, the first region 14 of the first lens 10 is symmetric with the first region 24 of the second lens 20 by rotating 180 degrees about an axis 50 perpendicular to Figure 8 the plane (i.e., perpendicular to the median plane of the lens), and the axis 50 is in the sagittal plane 30 of the spectacle lens 300. Similarly, the second region 15 of the first lens 10 is symmetric with the second region 25 of the second lens 20 by rotating 180 degrees about an axis 50 perpendicular to Figure 8 the plane (i.e., perpendicular to the median plane of the lens), and the axis 50 is in the sagittal plane 30 of the spectacle lens 300. Both the first region 14 and the second region 15 of the first lens 10 include an arrangement of micro-optical elements, and correspondingly, both the first region 24 and the second region 25 of the second lens 20 include an arrangement of micro-optical elements.

[0248] This means that both the first lens 10 and the second lens 20 have an optical design that includes the macro-optical components as described above and two micro-optical components respectively referred to as the first micro-optical component and the second micro-optical component.

[0249] The first micro-optical component of the first lens 10 is defined in the first region 14 of the first lens 10, and the second micro-optical component of the first lens 10 is defined in the second region 15 of the first lens 10. The first micro-optical component of the second lens 20 is defined in the first region 24 of the second lens 20, and the second micro-optical component of the second lens 20 is defined in the second region 25 of the second lens 20.

[0250] The characteristics of the micro-optical elements in the first region 14 of the first lens 10 are different from those of the micro-optical elements in the second region 15 of the first lens 10. For example, the number of micro-optical elements in the first region 14 of the first lens 10 is less than the number of micro-optical elements in the second region 15 of the first lens 10. In another example, the size of the micro-optical elements in the first region 14 is less than the size of the micro-optical elements in the second region 15 of the first lens 10.

[0251] Correspondingly, the characteristics of the micro-optical elements in the first region 24 of the second lens 20 are different from those of the micro-optical elements in the second region 25 of the second lens 20. For example, the number of micro-optical elements in the first region 24 of the second lens 20 is less than the number of micro-optical elements in the second region 25 of the second lens 20. In another example, the size of the micro-optical elements in the first region 24 is less than the size of the micro-optical elements in the second region 25 of the second lens 20.

[0252] On Figure 8 this, the first micro-optical component of the first lens 10 is similar to the first micro-optical component of the second lens 20. For this purpose, this means that:

[0253] - The arrangement of the micro-optical elements included in the first region 14 of the first lens 10 is similar to the arrangement of the micro-optical elements included in the first region 24 of the second lens 20, and

[0254] - The characteristics of the micro-optical elements in the first region 14 of the first lens 10 are similar to the characteristics of the micro-optical elements included in the first region 24 of the second lens 20.

[0255] In other words, the arrangement of the micro-optical elements in the first region 14 of the first lens 10 is symmetric to the arrangement of the micro-optical elements in the first region 24 of the second lens 20 by rotating 180 degrees around an axis 50 passing through the sagittal plane 30 and perpendicular to the midplane of the pair of spectacle lenses.

[0256] The second micro-optical component of the first lens 10 is similar to the second micro-optical component of the second lens 20. For this purpose, this means that:

[0257] - The arrangement of the micro-optical elements included in the second region 15 of the first lens 10 is the same as the arrangement of the micro-optical elements included in the second region 25 of the second lens 20, and

[0258] - The characteristics of the micro-optical elements in the second zone 15 of the first lens 10 are similar to the characteristics of the micro-optical elements included in the second zone 25 of the second lens 20.

[0259] In other words, the arrangement of the micro-optical elements in the second zone 15 of the first lens 10 is symmetric with the arrangement of the micro-optical elements in the second zone 25 of the second lens 20 by rotating 180 degrees about an axis 50 passing through the sagittal plane 30 and perpendicular to the median plane of the pair of spectacle lenses.

[0260] This embodiment provides a pair of spectacle lenses 300 that are easy to manufacture because the first lens 10 is similar to the second lens 20, and the second lens 20 is rotated 180 degrees about the axis 50.

[0261] However, compared with the arrangement of the micro-optical elements in the second zone 25 of the second lens 20, the arrangement of the micro-optical elements in the first zone 14 of the first lens 10 presents a difference in said characteristics. Similarly, compared with the arrangement of the micro-optical elements in the first zone 24 of the second lens 20, the arrangement of the micro-optical elements in the second zone 15 of the first lens 10 presents a difference in said characteristics.

[0262] Therefore, the arrangement of the micro-optical elements in the first zone 14 of the first lens 10 (or the first micro-optical function of the first lens 10) and the arrangement of the micro-optical elements in the second zone 25 of the second lens 20 (or the second micro-optical function of the second lens 20) are asymmetric with respect to the sagittal plane 30 of the pair of spectacle lenses 100.

[0263] Similarly, the arrangement of the micro-optical elements in the second zone 15 of the first lens 10 (or the second micro-optical function of the first lens 10) and the arrangement of the micro-optical elements in the second zone 25 of the second lens 20 (or the first micro-optical function of the second lens 20) are asymmetric with respect to the sagittal plane 30 of the pair of spectacle lenses 100.

[0264] In this example, the characteristics of the micro-optical elements in the first zone 14 of the first lens 10 and correspondingly in the second zone 14 of the second lens 20, as well as the characteristics of the micro-optical elements in the second zone 15 of the first lens 10 and correspondingly in the second zone 25 of the second lens 20, are all suitable for controlling myopia progression. Typically, the characteristics of the first zone 14 of the first lens 10 provide a first evolution control function for myopia for the wearer's first eye, and the characteristics of the second zone 15 of the first lens 10 provide a second evolution control function for myopia for the wearer's first eye. The characteristics of the first zone 24 of the second lens 20 provide a first evolution control function for myopia for the wearer's second eye, and the characteristics of the second zone 25 of the second lens 20 provide a second evolution control function for myopia for the wearer's second eye.

[0265] To this end, the intensity of the myopia control signal provided by the myopia second evolution control function of the micro-optical elements in the second zone 15 of the first lens 10 is, for example, greater than the intensity of the myopia control signal provided by the myopia first evolution control function of the micro-optical elements in the first zone 14 of the first lens 10. This is achieved, for example, by differences in the density and / or size and / or diopter of the micro-optical elements. Similarly, the intensity of the myopia control signal provided by the myopia second evolution control function of the micro-optical elements in the second zone 25 of the second lens 20 is greater than the intensity of the myopia control signal provided by the myopia first evolution control function of the micro-optical elements in the first zone 24 of the second lens 20. Thus, good visual acuity is provided for the eye (i.e., the first eye) located on one side of the first lens 10 in the upper half of the first lens 10 to ensure good visual performance of this eye, while providing a defocusing effect or a diffusive optical function to the other eye (i.e., the second eye). In contrast, good visual acuity is provided for the other eye located on one side of the second lens 20 in the lower half of the second lens 20 to ensure good visual performance of this other eye, while providing a defocusing effect or a diffusive optical function to the first eye.

[0266] According to this example, the characteristics (or parameters) of the first zone 14 of the first lens 10 and the second zone 25 of the second lens 20 can be selected to provide good visual performance when the wearer views an object located at a long distance from him (i.e., for example, an object located more than 5 meters from the wearer's eyes). Thus, in this example, the first zone 14 of the first lens 10 and the second zone 25 of the second lens 20 can be dedicated to distance vision.

[0267] In contrast, the characteristics of the second zone 15 of the first lens 10 and the first zone 24 of the second lens 20 can be selected to provide good visual performance when the wearer views an object located at a short distance and / or an intermediate distance from him (e.g., an object located less than 5 meters from the wearer's eyes). Thus, the second zone 15 of the first lens 10 and the first zone 24 of the second lens 20 can be dedicated to near vision and / or intermediate vision.

[0268] This embodiment allows taking into account the dominant eye that can change according to distance vision. Thus, this embodiment is configured to provide better visual acuity to the dominant eye according to distance vision.

[0269] Figure 9 An example of a pair of spectacle lenses 400 of the third embodiment disclosed above is shown. Thus, only the differences from Figure 8 the pair of spectacle lenses 300 shown will be disclosed. Figure 8 the pair of spectacle lenses 300 shown will be disclosed.

[0270] In Figure 9Above, the arrangement of the micro-optical elements in the first zone 14 of the first lens 10 and the arrangement of the micro-optical elements in the first zone 24 of the second lens 20 are each composed of three arcs centered on the optical centers 19, 29 of the central zones 12, 22. In this example, under standard wearing conditions, when looking straight ahead at infinity, the optical center 19 of the central zone is aligned with the visual axis of the wearer's first eye, and the optical center 29 of the central zone of the second lens 20 is aligned with the visual axis of the wearer's second eye.

[0271] In contrast, the arrangement of the micro-optical elements in the second zone 15 of the first lens 10 and the arrangement of the micro-optical elements in the second zone 25 of the second lens 20 are each composed of five arcs centered on the optical centers of the central zones 19, 29.

[0272] In Figure 9 above, the number of micro-optical elements in the second zone 15 of the first lens 10 is greater than the number of micro-optical elements in the first zone 14 of the first lens 10, and correspondingly, the number of micro-optical elements in the second zone 25 of the second lens 20 is greater than the number of micro-optical elements in the first zone 24 of the second lens 20.

[0273] In addition, the size (i.e., diameter) of the micro-optical elements included in the first zone 14 of the first lens 10 and the micro-optical elements included in the first zone 24 of the second lens 20 is smaller than the size of the micro-optical elements included in the second zone 15 of the first lens 10 and the micro-optical elements included in the second zone 25 of the second lens 20.

[0274] For example, the micro-optical elements included in the second zone 15 of the first lens 10 and the micro-optical elements included in the second zone 25 of the second lens 20 have a diameter of 1 mm, and the micro-optical elements included in the first zone 14 of the first lens 10 and the micro-optical elements included in the first zone 24 of the second lens 20 have a diameter of 2 mm.

[0275] Combined Figure 10 A fourth embodiment of a pair of spectacle lenses 500 according to the present disclosure is described.

[0276] In this embodiment, the first lens 10 and the second lens 20 include central zones 12, 22. The central zone 12 of the first lens 10 does not have any optical elements, and the central zone 22 of the second lens 20 does not have any optical elements.

[0277] In this embodiment, both the first lens 10 and the second lens 20 are divided into five complementary regions, namely, the central regions 12, 22 and four quadrant regions at 45 degrees respectively defining the first regions 14, 24, the second regions 15, 25, the third regions 16, 26 and the fourth regions 17, 27. The first regions 14, second regions 15, third regions 16 and fourth regions 17 of the first lens 10 constitute the first peripheral region 13 of the first lens 10, and correspondingly, the first regions 24, second regions 25, third regions 26 and fourth regions 27 of the second lens 20 constitute the first peripheral region 23 of the second lens 20. In addition, each of the four quadrants of the first lens 10 includes an arrangement of micro-optical elements, and correspondingly, each of the four quadrants of the second lens 20 includes an arrangement of micro-optical elements. The four quadrants of the first lens 10 are defined within the first peripheral region 13 of the first lens 10, and the four quadrants of the second lens 20 are defined within the first peripheral region 23 of the second lens 20. In this example, the first peripheral region 13 of the first lens 10 is divided into four quadrants having two orthogonal axes (referred to as the first axis 81 and the second axis 82 of the first lens 10). The first axis 81 of the first lens 10 is inclined 45 degrees with respect to the axis 40 by rotating 45 degrees (counterclockwise) about the ophthalmic lens center V10 of the first lens 10, and the second axis 82 of the first lens 10 is inclined 45 degrees with respect to the axis 40 by rotating 45 degrees (clockwise) about the ophthalmic lens center V10 of the first lens 10. Similarly, the first peripheral region 23 of the second lens 20 is divided into four quadrants having two orthogonal axes (referred to as the first axis 91 and the second axis 92 of the second lens 20). The first axis 91 of the second lens 20 is inclined 45 degrees with respect to the axis 40 by rotating 45 degrees (counterclockwise) about the ophthalmic lens center V20 of the second lens 20, and the second axis 92 of the second lens 20 is inclined 45 degrees with respect to the axis 40 by rotating 45 degrees (clockwise) about the ophthalmic lens center V20 of the second lens 20.

[0278] On Figure 10 the upper part of the first lens, the first region 14 of the first lens is disposed in the upper part of the first lens 10, and correspondingly, the second region 25 of the second lens is disposed in the upper part of the second lens 20. The second region 15 of the first lens is disposed in the lower part of the first lens 10, and correspondingly, the first region 24 of the second lens is disposed in the lower part of the second lens 20. The third region 16 of the first lens 10 is disposed on the temporal side of the pair of spectacle lenses, and correspondingly, the third region 26 of the second lens 20 is disposed on the temporal side of the pair of spectacle lenses. The fourth region 17 of the first lens 10 is disposed on the nasal side of the pair of spectacle lenses, and correspondingly, the fourth region 27 of the second lens 20 is disposed on the nasal side of the pair of spectacle lenses.

[0279] The first zone 14 of the first lens is positioned above the ophthalmic lens center V10 of the first lens 10, and the second zone 15 of the first lens 10 is symmetric with the first zone 14 by rotating 180 degrees about an axis z1 (transverse axis z) that passes through the ophthalmic lens center V10 of the first lens 10 and is transverse to the axis 40. The third zone 16 of the first lens 10 is positioned on the right side of the ophthalmic center V10 of the first lens 10, and the fourth zone 17 of the first lens 10 is symmetric with the third zone 16 by rotating 180 degrees about an axis z1 that passes through the ophthalmic lens center V10 of the first lens 10 and the eye rotation center of the eye covered by the first lens 10. i ) Rotating 180 degrees makes it symmetric with the first zone 14. The third zone 16 of the first lens 10 is positioned on the right side of the ophthalmic center V10 of the first lens 10, and the fourth zone 17 of the first lens 10 is symmetric with the third zone 16 by rotating 180 degrees about an axis z1 that passes through the ophthalmic lens center V10 of the first lens 10 and the eye rotation center of the eye covered by the first lens 10.

[0280] On Figure 10 the first zone 24 of the second lens 20 is positioned below the ophthalmic lens center V20 of the second lens 20, and the second zone 25 of the second lens 20 is symmetric with the first zone 24 by rotating 180 degrees about an axis z2 (transverse axis) that passes through the ophthalmic lens center V20 of the second lens 20 and is transverse to the axis 40. The third zone 26 of the second lens 20 is positioned on the left side of the ophthalmic center V20 of the second lens 20, and the fourth zone 27 of the second lens 20 is symmetric with the third zone 26 by rotating 180 degrees about a transverse axis z2 that passes through the ophthalmic lens center V20 of the second lens 10 and the eye rotation center of the eye covered by the second lens 20.

[0281] The first zone 14 of the first lens 10 is the same as the first zone 24 of the second lens 20, the second zone 15 of the first lens 10 is the same as the second zone 25 of the second lens 20, the third zone 16 of the first lens 10 is the same as the third zone 26 of the second lens 20, and correspondingly, the fourth zone 17 of the first lens 10 is the same as the fourth zone 27 of the second lens 20. For this reason, the first zone 14 of the first lens 10 is symmetric with the first zone 24 of the second lens 20 by rotating 180 degrees about an axis 50 perpendicular to Figure 10 the plane (i.e., perpendicular to the median plane of the lens), and the axis 50 is in the sagittal plane 30 of the spectacle lens 500. Similarly, the second zone 15 of the first lens 10 is symmetric with the second zone 25 of the second lens 20 by rotating 180 degrees about an axis 50 perpendicular to Figure 10 the plane. The third zone 16 of the first lens 10 is symmetric with the third zone 26 of the second lens 20 by rotating 180 degrees about an axis 50 perpendicular to Figure 10 the plane, and the fourth zone 17 of the first lens 10 is symmetric with the fourth zone 27 of the second lens 20 by rotating 180 degrees about an axis 50 perpendicular to Figure 10 the plane.

[0282] The first zone 14, second zone 15, third zone 16, and fourth zone 17 of the first lens 10 each include an arrangement of micro-optical elements, and correspondingly, the first zone 24, second zone 25, third zone 26, and fourth zone 27 of the second lens 20 each include an arrangement of micro-optical elements.

[0283] This means that both the first lens 10 and the second lens 20 have an optical design that includes the macro-optical components as described above and fourth micro-optical components respectively referred to as the first micro-optical component, second micro-optical component, third micro-optical component, and fourth micro-optical component.

[0284] The first micro-optical component of the first lens 10 is defined in the first zone 14 of the first lens 10, the second micro-optical component of the first lens 10 is defined in the second zone 15 of the first lens 10, the third micro-optical component of the first lens 10 is defined in the third zone 16 of the first lens 10, and the fourth micro-optical component of the first lens 10 is defined in the fourth zone 17 of the first lens 10. The first micro-optical component of the second lens 20 is defined in the first zone 24 of the second lens 20, the second micro-optical component of the second lens 20 is defined in the second zone 25 of the second lens 20, the third micro-optical component of the second lens 20 is defined in the third zone 26 of the second lens 20, and the fourth micro-optical component of the second lens 20 is defined in the fourth zone 27 of the second lens 20.

[0285] On Figure 10 this, the first micro-optical component of the first lens 10 is similar to the first micro-optical component of the second lens 20. For this reason, this means that:

[0286] - The arrangement of the micro-optical elements included in the first zone 14 of the first lens 10 is similar to the arrangement of the micro-optical elements included in the first zone 24 of the second lens 20, and

[0287] - The characteristics of the micro-optical elements in the first zone 14 of the first lens 10 are similar to the characteristics of the micro-optical elements included in the first zone 24 of the second lens 20.

[0288] In other words, the arrangement of the micro-optical elements in the first zone 14 of the first lens 10 is symmetric with the arrangement of the micro-optical elements in the first zone 24 of the second lens 20 by rotating 180 degrees about an axis 50 passing through the sagittal plane 30 and perpendicular to the median plane of the pair of spectacle lenses.

[0289] The second micro-optical component of the first lens 10 is similar to the second micro-optical component of the second lens 20. For this reason, this means that:

[0290] - The arrangement of the micro-optical elements included in the second zone 15 of the first lens 10 is the same as the arrangement of the micro-optical elements included in the second zone 25 of the second lens 20, and

[0291] - The characteristics of the micro-optical elements in the second zone 15 of the first lens 10 are similar to those of the micro-optical elements included in the second zone 25 of the second lens 20.

[0292] In other words, the arrangement of the micro-optical elements in the second zone 15 of the first lens 10 is symmetric to the arrangement of the micro-optical elements in the second zone 25 of the second lens 20 by rotating 180 degrees around an axis 50 passing through the sagittal plane 30 and perpendicular to the median plane of the spectacle lens.

[0293] The third micro-optical component of the first lens 10 is similar to the third micro-optical component of the second lens 20. For this purpose, this means that:

[0294] - The arrangement of the micro-optical elements included in the third zone 16 of the first lens 10 is similar to the arrangement of the micro-optical elements included in the third zone 26 of the second lens 20, and

[0295] - The characteristics of the micro-optical elements in the third zone 16 of the first lens 10 are similar to those of the micro-optical elements included in the third zone 26 of the second lens 20.

[0296] In other words, the arrangement of the micro-optical elements in the third zone 16 of the first lens 10 is symmetric to the arrangement of the micro-optical elements in the third zone 26 of the second lens 20 by rotating 180 degrees around an axis 50 passing through the sagittal plane 30 and perpendicular to the median plane of the spectacle lens.

[0297] The fourth micro-optical component of the first lens 10 is similar to the fourth micro-optical component of the second lens 20. For this purpose, this means that:

[0298] - The arrangement of the micro-optical elements included in the fourth zone 17 of the first lens 10 is the same as the arrangement of the micro-optical elements included in the fourth zone 27 of the second lens 20, and

[0299] - The characteristics of the micro-optical elements in the fourth zone 17 of the first lens 10 are similar to those of the micro-optical elements included in the fourth zone 27 of the second lens 20.

[0300] In other words, the arrangement of the micro-optical elements in the second fourth 17 of the first lens 10 is symmetric to the arrangement of the micro-optical elements in the fourth zone 27 of the second lens 20 by rotating 180 degrees around an axis 50 passing through the sagittal plane 30 and perpendicular to the median plane of the spectacle lens.

[0301] The characteristics of the micro-optical elements in the first zone 14 of the first lens 10 are different from those of the micro-optical elements in the second zone 15 of the first lens 10, different from those of the optical elements in the third zone 16 of the first lens 10, and different from those of the micro-optical elements in the fourth zone 17 of the second lens 20.

[0302] Correspondingly, the characteristics of the micro-optical elements in the first zone 24 of the second lens 20 are different from those of the micro-optical elements in the second zone 25 of the second lens 20, different from those of the micro-optical elements in the third zone 26 of the second lens 20, and different from those of the micro-optical elements in the fourth zone 27 of the second lens 20.

[0303] In other words, this means that:

[0304] - The arrangement of the micro-optical elements in the first zone 14 of the first lens 10 and the arrangement of the micro-optical elements in the second zone 25 of the second lens 20 are asymmetric with respect to the sagittal plane 30 of the pair of spectacle lenses;

[0305] - The arrangement of the micro-optical elements in the second zone 15 of the first lens 10 and the arrangement of the micro-optical elements in the first zone 24 of the second lens 20 are asymmetric with respect to the sagittal plane 30 of the pair of spectacle lenses.

[0306] In Figure 10 terms, the characteristics of the micro-optical elements in the first zones 14, 24 of the first lens 10 and the second lens 20, the characteristics of the micro-optical elements in the second zones 15, 25 of the first lens 10 and the second lens 20, the characteristics of the micro-optical elements in the third zones 16, 26 of the first lens 10 and the second lens 20, and the characteristics of the micro-optical elements in the fourth zones 17, 27 of the first lens 10 and the second lens 20 are all suitable for controlling myopia progression.

[0307] Typically, the first zone 14 of the first lens 10 is characterized by providing a first myopia evolution control function for the first eye of the wearer, the second zone 15 of the first lens 10 is characterized by providing a second myopia evolution control function for the first eye of the wearer, the third zone 16 of the first lens 10 is characterized by providing a third myopia evolution control function for the first eye of the wearer, and the fourth zone 17 of the first lens 10 is characterized by providing a fourth myopia evolution control function for the first eye of the wearer.

[0308] Similarly, the first zone 24 of the second lens 20 is characterized by providing a first myopia evolution control function for the second eye of the wearer, the second zone 25 of the second lens 20 is characterized by providing a second myopia evolution control function for the second eye of the wearer, the third zone 26 of the second lens 20 is characterized by providing a third myopia evolution control function for the second eye of the wearer, and the fourth zone 27 of the second lens 20 is characterized by providing a fourth myopia evolution control function for the second eye of the wearer.

[0309] To this end, the intensity of the myopia control signal provided by the myopia second evolution control function of the micro-optical elements in the second zone 15 of the first lens 10 is greater than the intensity of the myopia control signal provided by the myopia first evolution control function of the micro-optical elements in the first zone 14 of the first lens 10. This is achieved, for example, by differences in the density and / or size and / or diopter of the micro-optical elements.

[0310] In this example, the characteristics of the micro-optical elements in the third zone 16 are the same as those of the micro-optical elements in the fourth zone 17 of the first lens 10. With such characteristics, the arrangement of the micro-optical elements in the third zone 16 and the arrangement of the micro-optical elements in the fourth zone 17 are similar, thus making the manufacturing process of the pair of spectacle lenses 500 easier. In addition, the intensity of each of the myopia control signals provided by the myopia third evolution control function and the myopia fourth evolution control function of the micro-optical elements in the third zone 16 and the fourth zone 17 of the first lens 10 is greater than the intensity of the myopia control signal provided by the myopia first evolution control function of the micro-optical elements in the first zone 14 of the first lens 10. This is achieved, for example, by differences in the density and / or size and / or diopter of the micro-optical elements.

[0311] The intensity of each of the myopia control signals provided by the myopia third evolution control function and the myopia fourth evolution control function of the micro-optical elements in the third zone 16 and the fourth zone 17 of the first lens 10 is less than the intensity of the myopia control signal provided by the myopia second evolution control function of the micro-optical elements in the second zone 15 of the first lens 10. This is achieved, for example, by differences in the density and / or size and / or diopter of the micro-optical elements.

[0312] Therefore, the quadrant related to the first zone 14 of the first lens 10 provides good visual acuity when the wearer views an object located at a long distance from him (i.e., for example, an object located more than 5 meters away from the wearer's eyes), thus allowing to ensure good visual performance. Therefore, the first part 14 of the first lens 10 can be dedicated to distance vision. In contrast, the second zone 15 of the first lens 10 can be dedicated to myopia evolution control growth, like the third zone 16 and the fourth zone 17 of the first lens 10.

[0313] In this example, the characteristics of the micro-optical elements in the third zone 26 can be the same as those of the micro-optical elements in the fourth zone 27 of the second lens 20. With such characteristics, the arrangements of the micro-optical elements in the third zone 26 and the fourth zone 27 are similar. Additionally, the intensities of the myopia control signals provided by the myopia third evolution control function and the fourth evolution control function of the micro-optical elements in the third zone 26 and the fourth zone 27 of the second lens 20 are each greater than the intensity of the myopia control signal provided by the myopia second evolution control function of the micro-optical elements in the first zone 24 of the second lens 20. This is achieved, for example, by differences in the density and / or size and / or diopter of the micro-optical elements.

[0314] Then, the intensities of the myopia control signals provided by the myopia third evolution control function and the fourth evolution control function of the micro-optical elements in the third zone 26 and the fourth zone 27 of the second lens 20 are each less than the intensity of the myopia control signal provided by the myopia second evolution control function of the micro-optical elements in the second zone 25 of the second lens 20. This is achieved, for example, by differences in the density and / or size and / or diopter of the micro-optical elements.

[0315] Therefore, the quadrant in the second lens 20 related to the first zone 24 of the second lens 20 provides good visual acuity, for example, when the wearer views an object positioned at a short distance and / or intermediate distance from him (i.e., an object positioned, for example, less than 5 meters from the wearer's eyes), thus allowing for ensuring good visual performance. Therefore, the first part 24 of the second lens 20 can be dedicated to near vision and / or intermediate vision. In contrast, the second zone 25 of the second lens 20, like the third zone 26 and the fourth zone 27 of the second lens 20, can be dedicated to myopia evolution control.

[0316] Typically, the first zones 14, 24 of the first lens 10 and the second lens 20 each include contiguous micro-optical elements (microlenses) with a diameter of 1 mm and a diopter between 0 diopters and 10 diopters, preferably equal to 4 diopters.

[0317] The second zones 15, 25 of the first lens 10 and the second lens 20 each include microlenses with a diameter of 1 mm and a diopter between 1 diopter and 10 diopters, preferably equal to 4 diopters. Each micro-optical element in the second zones 15, 25 of the first lens 10 and the second lens 20 is spaced edge-to-edge from an adjacent micro-optical element by at least 0.1 mm, typically 1 mm. The density of the arrangement of the micro-optical elements on the second zones 15, 25 of the first lens 10 and the second lens 20 is 50%.

[0318] The third zones 16, 26 and fourth zones 17, 27 of the first lens 10 and the second lens 20 include microlenses having a diameter of 1 mm and a diopter between 1 diopter and 10 diopters, preferably equal to 4 diopters. Each micro-optical element in the third zones 16, 26 and fourth zones 17, 27 of the first lens 10 and the second lens 20 is spaced edge-to-edge from an adjacent micro-optical element by at least 0.1 mm, typically 1 mm. The density of the arrangement of the micro-optical elements on the third zones 16, 26 and fourth zones 17, 27 of the first lens 10 and the second lens 20 is 30%.

[0319] This embodiment also allows for the dominant eye, which can vary according to distance vision, to be taken into account. Thus, this embodiment is configured to provide better visual acuity to the dominant eye according to distance vision. Since more zones are defined in the optical design of the first lens 10 and the second lens 20, the correction according to the dominant eye is improved.

[0320] In a variant, it should be noted that Figures 1 to 4 the optical design of the first lens 10 in the pair of spectacle lenses disclosed can be combined with Figure 10 the optical design of the second lens 20 in the pair of spectacle lenses disclosed, as Figure 5 and Figure 6 explained. Additionally, Figures 1 to 4 the optical design of the first lens 10 in the pair of spectacle lenses disclosed can be combined with Figures 8 to 9 the optical design of the second lens 20 in the pair of spectacle lenses disclosed to form a fifth embodiment (not shown) of a pair of spectacle lenses. Similarly, Figures 1 to 4 the optical design of the second lens 20 in the pair of spectacle lenses disclosed can be combined with Figures 8 to 9 or Figure 10 the optical design of the first lens in the pair of spectacle lenses disclosed to form a sixth embodiment (not shown) of a pair of spectacle lenses.

[0321] Therefore, it should be understood that any optical design of the first lens 10 disclosed in this disclosure can be combined with any optical design of the second lens 20 disclosed in this disclosure, provided that the arrangement of the micro-optical elements of the first lens is asymmetric with respect to the arrangement of the micro-optical elements of the second lens.

[0322] Additionally, the form of the lens or zone is not limited to the examples shown in the drawings.
