Description

[Technical Field]

[0001] The present invention relates to a pair of eyeglass lenses for reducing the progression of myopia, 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 the wearer's second eye, each of which has an arrangement of micro-optical elements that induce blur. The present invention also refers to vision compensation eyeglasses 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 the wearer's second eye, each of which has an arrangement of micro-optical elements.

[0002] More precisely, the invention relates to a pair of spectacle lenses having a particular design that induces a particular blur or defocus effect. [Background technology]

[0003] Myopia of the eye is characterized by the fact that the eye focuses light from a distance in front of the retina. In other words, the myopic eye exhibits a length that is not suitable for clear vision. Myopia has both genetic and environmental origins. In the latter case, it develops, for example, due to an increase in close vision tasks, but also due to a decrease in outdoor activities.

[0004] Many solutions exist that aim to reduce the progression of myopia. For example, it is known to use a pair of lenses, each of which is positioned to be worn in front of one of the subject's eyes and has micro-optical elements configured to allow clear vision in the foveal region of the eye while inducing blur in the peripheral vision region. Although these solutions are functional, they do not distinguish between the specificities of the two eyes, such as the dominant eye, and therefore the design of these lenses is not adequately adapted to the specificities of each eye. In addition, these solutions do not take into account all the specificities of each eye of the subject, which can alter the subject's visual acuity. Summary of the Invention [Problem to be solved by the invention]

[0005] In this context, one object of the present invention is to provide a solution that allows managing myopia progression in both eyes with a better trade-off between visual acuity and myopia progression control. [Means for solving the problem]

[0006] The above object is achieved according to the present invention by providing a pair of spectacle lenses comprising a first optical lens intended to be worn in front of a first eye of a wearer and a second optical lens intended to be worn in front of a second eye of the wearer, - the first optical lens includes an arrangement of micro-optical elements; the second optical lens includes an arrangement of micro-optical elements; 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.

[0007] 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 in the symmetry areas of the first lens and the second lens, and the symmetry area of ​​the first lens is symmetrical to the symmetry area of ​​the second lens with respect to the sagittal plane of the pair of spectacle lenses.

[0008] Due to the optical design of the first and second lenses, the pair of spectacle lenses accounts for the specificities of both eyes, such as the dominant eye. Specifically, the design of each eye is adapted to the dominant or non-dominant eye, respectively. As a result, the pair of spectacle lenses offers a good trade-off between visual acuity and myopic discomfort and progression control, which are managed binocularly using the specific optical design of the first and second lenses.

[0009] According to one embodiment, the sagittal plane of a pair of spectacle lenses passes equidistantly between the first lens and the second lens.

[0010] According to one embodiment, the arrangement of the micro-optical elements of the first optical lens is different from the arrangement of the micro-optical elements of the second optical lens in accordance with the following criteria: - density of micro-optical elements, - the diopter power of the micro-optical element, - the geometry of the micro-optical elements, - refractive, diffractive or diffusive optical functions of micro-optical elements, - focal length of micro-optical elements, - diameter of the micro-optical element, - the position of the arrangement of micro-optical elements in the field of view of the first optical lens and the second optical lens, - the position of the micro-optical element in the arrangement of micro-optical elements differ in at least one of the following:

[0011] According to one embodiment, at least one of the first and second optical lenses comprises a central zone having micro-optical elements.

[0012] According to one embodiment, at least one of the first and second optical lenses comprises a central zone that is free of any micro-optical elements.

[0014] According to one embodiment, the arrangement of the micro-optical elements of at least one of the first and second optical lenses comprises at least one circular arc having its center in the central zone.

[0015] According to one embodiment, the first optical lens and the second optical lens are each divided into at least three complementary zones: a central zone, a first zone, and a second zone, and the arrangement of the micro-optical elements in the first zone of the first optical lens is different from the arrangement of the micro-optical elements in the second zone of the first optical lens, and the arrangement of the micro-optical elements in the first zone of the second optical lens is different from the arrangement of the micro-optical elements in the second zone of the second optical lens, and the arrangement of the micro-optical elements in the first zone of the first optical lens is symmetrical to the arrangement of the micro-optical elements in the first zone of the second optical lens by rotating 180 degrees around an axis passing through the sagittal plane of the pair of eyeglass lenses and perpendicular to the average plane of the pair of eyeglass lenses.

[0016] According to another embodiment, the first optical lens and the second optical lens are each divided into five complementary zones, a central zone and four 45-degree quadrants defining first, second, third and fourth zones, respectively, wherein the arrangement of the micro-optical elements in the first zone of the first optical lens is different from the arrangement of the micro-optical elements in the second, third and fourth zones of the first optical lens, the arrangement of the micro-optical elements in the first zone of the second optical lens is different from the arrangement of the micro-optical elements in the second, third and fourth zones of the second optical lens, and the arrangement of the micro-optical elements in the first and second zones of the first optical lens is symmetrical to the respective arrangement of the micro-optical elements in the first and second zones of the second lens by a 180 degree rotation around an axis passing through the sagittal plane of the pair of spectacle lenses and perpendicular to the mean plane of the pair of spectacle lenses.

[0017] Typically, the arrangement of the micro-optical elements in the second zone of the first optical lens is different from the arrangement of the micro-optical elements in the third and fourth zones of the first optical lens, and the arrangement of the micro-optical elements in the second zone of the second optical lens is different from the arrangement of the micro-optical elements in the third and fourth zones of the second optical lens.

[0018] According to a further aspect, the arrangement of the micro-optical elements in the third zone of the first optical lens is similar to the arrangement of the micro-optical elements in the fourth zone of the first optical lens, and the arrangement of the micro-optical elements in the third zone of the second optical lens is similar to the arrangement of the micro-optical elements in the fourth zone of the second optical lens.

[0019] Advantageously, at least one micro-optical element of the first and second optical lenses is adjacent.

[0020] According to a further aspect, the arrangement of the micro-optical elements of the optical lenses is configured such that the first optical lens and the second optical lens each comply with an optical criterion based on a modulation transfer function.

[0021] Advantageously, the optical fiducial of the first optical lens differs from the optical fiducial of the second optical lens in a different range of spatial frequencies, for example comprised 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.

[0022] Advantageously, the first optical lens and the second optical lens each comprise an optical axis and a horizontal axis and a vertical axis both transverse to the optical axis, and at least one optical metric of the first optical lens and the second optical lens exhibits a variation along the horizontal axis and a variation along the vertical axis, said variation along the vertical axis being different from the variation along the horizontal axis.

[0023] According to a particular advantageous aspect, the arrangement of the micro-optical elements of at least one of the first and second optical lenses comprises: a refractive micro-lens, a diffractive or diffusing micro-lens, a pyramidal Fresnel micro-lens, a micro-prism, a micro-diffuser, a micro-diffraction grating, a scattering dot, a Fresnel structure or a toroidal structure.

[0024] According to a particular advantageous aspect, the arrangement of the micro-optical elements of the first and second optical lenses is adapted based on the dominant eye of the wearer.

[0025] According to a particular advantageous aspect, at least one of the optical lenses has at least one predetermined refractive power so as to provide a refractive correction to the wearer's eye.

[0026] The invention further relates to vision compensation spectacles for managing the progression of myopia, comprising a frame as disclosed above and a pair of spectacle lenses.

[0029] In this description, terms such as "horizontal," "vertical," "upper," "lower," "front," "rear," "left," "right," or other words indicating relative positions may be used, which should be understood in the context of wearing a pair of eyeglass lenses according to the present disclosure.

[0030] definition FIG. 12 is a diagram of the top half of a first lens 10 and a first eye of a wearer, or the top half of a second lens 20 and a second eye of a wearer, illustrating the definitions used herein.

[0031] In FIG. 12, a first lens 10 is placed in front of a first eye, or respectively a second lens 20 is placed in front of a second eye of the wearer.

[0032] At least one of the first lens and the second lens has at least one predetermined refractive power that provides refractive correction for the corresponding eye of the wearer.

[0033] In the following example, the first lens 10 has an ophthalmic lens center V10 and the second lens 20 has an ophthalmic lens center V20, respectively. The center of an ophthalmic lens may be the optical center or the geometric center of the ophthalmic lens. The posterior surface of the first lens 10 or the second lens 20 is the surface of the first lens 10 or the second lens 20 that is closest to the wearer's eye.

[0034] The 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).

[0035] The central vision gaze direction is defined by two angles (αC, βC) that represent the rotation of the eye from the main gaze direction. More precisely, the angles βC and αC represent the horizontal and vertical rotation angles applied to the eye rotation center ERC in the Fick system to move the eye from the main gaze reference axis to the gaze axis. A third torsional rotation of the eye derived from these two angles is applied, so that the gaze axis respects the List law. Figure 12 shows an example of the angles αC and βC relative to the eye rotation center ERC and the first lens 10. The central vision gaze direction can be represented by a line passing through the eye rotation center ERC.

[0036] The angle αC is defined in a vertical plane passing through the eye's center of rotation ERC, and the angle βC is defined in a horizontal plane passing through the eye's center of rotation ERC. The angle αC is defined as positive when the wearer's eye looks down and negative when the wearer's eye looks up. The angle βC is defined as positive when the wearer's eye looks nasally and negative when the wearer's eye looks temporally. The pantoscopic angle is the angle in the vertical plane between the normal to the rear surface of the first or second optical lens 10, 20 and the visual axis of the eye (axis z1, z2) in its primary position, defined as the horizontal direction, when the wearer gazes straight ahead at infinity.

[0037] The cornea-to-lens distance is the distance along the visual axis of the eye between the cornea and the back surface of the first or second lens 10,20 at its primary position.

[0038] FIG. 13 shows a first lens 10 and a second lens 20 mounted in a frame 70 of vision compensation glasses. The frame 70 includes temples 71. Herein, the sagittal plane 30 of the glasses is defined as a plane equidistant from the vertical sides of two rectangular boxes, and the first and second lenses are inscribed when mounted in the frame 70. Typically, when a wearer wears a pair of glasses in front of their eyes, the sagittal plane 30 of the glasses merges with the wearer's sagittal plane. Herein, the mean plane of the pair of glasses lenses is defined as the plane located the smallest distance from the rear surfaces of the two lenses 10 and 20. An axis 50 is defined that passes through the sagittal plane 30 of the pair of glasses lenses and is perpendicular to the mean plane of the pair of glasses lenses. Herein, the secondary axis 40 of the glasses lenses is defined as an axis that passes through the ophthalmic lens centers V10 and V20 of the two lenses 10 and 20 and intersects the sagittal plane 30. Of course, when the first lens 10 and the second lens 20 are mounted in the frame 70, the sagittal plane 30 of the pair of spectacle lenses corresponds to the sagittal plane of the wearer.

[0039] The expression sagittal plane of the wearer refers to the median plane of the segment whose end is the centre of rotation of the eye.

[0040] In this disclosure, the sagittal plane of the eyeglasses is aligned with the sagittal plane of the wearer.

[0041] 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.

[0042] The interpupillary distance, denoted IPD, is the distance between the centers of the pupils of the wearer's eyes in their primary position when the head is in an upright position and the gaze direction is not focused along the horizon in the wearer's sagittal plane, e.g., when looking at infinity (see Figure 13).

[0043] In this application, the term "micro-optical element" refers to various types of micro-optical elements, each fabricated with relatively small dimensions, e.g., less than 2.5 mm. Micro-optical elements include, for example, lenses, pyro-Fresnel lenses, prisms, diffusers, beam splitters, or diffraction gratings. The term "micro-optical element" refers to a set of multiple similar micro-optical elements, ranging from about 10 micro-optical elements to hundreds or thousands of micro-optical elements, depending on their individual sizes and various arrangements. Micro-optical elements are generally formed by photolithography, holography, molding, machining, or encapsulation.

[0044] Below, a pair of spectacle lenses is placed to control the progression of myopia.

[0045] device A first embodiment of a pair of eyeglass lenses 100 according to the present disclosure will be described with reference to FIGS. 1 to 4 and 11. FIG.

[0046] The pair of eyeglass lenses 100 of FIG. 1 includes a first optical lens 10 and a second optical lens 20 .

[0047] The first optical lens 10 is intended to be placed in front of a first eye of a wearer, and the second optical lens 20 is intended to be placed in front of a second eye of a wearer, where the first eye refers to, for example, the left eye of the wearer, and the second eye refers to, for example, the right eye of the wearer.

[0048] Hereinafter, the first optical lens 10 will be referred to as the first lens 10, and the second optical lens 20 will be referred to as the second lens 20.

[0049] 11 shows an example of the first optical lens 10 or the second optical lens 20. The first lens 10 or the second lens 20 is here a biconvex lens, but may alternatively be a concave-convex lens or a plano-convex lens.

[0050] The first lens 10 or the second lens 20 shown in Figure 11 has two opposing optical surfaces, a front surface F1 facing the object side and a rear surface F2 closest to the wearer's eye. The first lens 10 or the second lens 20 typically presents a center V10, V20 that is the optical or geometric center of the first lens 10 or the second lens 20. In the present disclosure, as shown in Figures 1 and 11, the first lens 10 is defined in a first Cartesian reference coordinate system (V10, x1, y1, z1) and the second lens 20 is defined in a second Cartesian reference coordinate system (V20, x1, y1, z1).

[0051] The first lens 10 has an optical design that includes macro- and micro-optical components.

[0052] The micro-optical components of the optical design (also called "micro-optical design") of the first lens 10 are made up of several micro-optical elements 1 arranged on at least one of the front and rear surfaces of the first lens 10, preferably on the convex front surface.

[0053] The macro-optical components of the optical design of the first lens 10 (also referred to as "macro-optical design") provide a macro-optical function that provides at least one overall refractive power over most or all of the useful surface area of ​​the first lens 10, providing a refractive correction to the wearer's eye that matches the wearer's refractive correction needs under wearing conditions. Thus, the macro-optical components of the first lens 10 have at least one predetermined refractive power that provides a first refractive correction for the wearer's first eye. For example, this macro-optical function is provided by the geometry of the front surface F1 or the back surface F2, or both, 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 is generally comprised between ±0.25 and ±15 diopters.

[0054] The overall refractive power provided by the macro-optical design of the first lens 10 includes at least spherical and / or cylindrical powers and prism deviation powers depending on the wearer's corrective needs as determined by an eye care professional to correct the wearer's vision defects. Typically, the overall refractive power corresponds to the refractive correction based on the wearer's prescription, for example, under standard wearing conditions. For example, a prescription for a wearer with refractive error includes values ​​for power and / or astigmatism, including cylinder and distance and / or near vision axes. Preferably, the overall refractive power of the first lens 10 includes a spherical toroidal power.

[0055] The term "prescription" should be understood to mean a set of refractive power, astigmatism (e.g., type of sphere S, cylinder C, and axis A), and / or prismatic deviation characteristics determined by an eye care practitioner to correct a wearer's vision deficiency. For example, a prescription for an ametropic wearer will include values ​​of refractive power and astigmatism (S, C, A) for distance and / or near vision.

[0056] The wearing conditions should 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 wearer's eye. The wearing conditions are defined below according to physiological parameters or parameters of the frame 70 when the frame 70 is worn by the wearer. For example, the wearing conditions include, for example, the angle of anteversion when worn, the distance from the cornea to the lens, the distance from the pupil to the cornea, the distance from the eye rotation center (ERC) to the pupil, and the angle of rotation.

[0057] An example of a standard wearing condition may be defined by a forward tilt angle of -8° for adults or 0°-5° for children, a cornea-to-lens distance of 12 mm, a pupil-to-cornea distance of 2 mm, an ERC-to-pupil distance of 11.5 mm, and a wrap angle of 0°.

[0058] Each micro-optical element 1 has its own optical function and has a small dimension of less than 2 mm, preferably less than 1 mm. Each micro-optical element 1 may be, for example, a microlens, a pyramidal Fresnel lens, a prism, a diffuser, a beam splitter, or a diffraction grating. Micro-optical elements are typically formed by photolithography, holography, molding, machining, or encapsulation.

[0059] The micro-optical elements 1 of the first lens 10 form an arrangement 11 of micro-optical elements.

[0060] This arrangement of all micro-optical elements 11 provides a micro-optical function that is separate from and in addition to the macro-optical function of the first lens 10. Thus, the overall optical function of the first lens 10 is the addition of its macro-optical function and its micro-optical function, respectively, provided by the macro-optical and micro-optical components 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 its macro-optical design, i.e., without any overall optical power over most or all of the useful 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, i.e., without any micro-optical elements.

[0061] Similarly, the second lens 20 has an optical design including macro- and micro-optical components as described above.

[0062] Preferably, the overall refractive power of the second lens 20 includes a spherical toroidal power.

[0063] The micro-optical elements 1 of the second lens 20 form an arrangement 21 of micro-optical elements.

[0064] This arrangement 21 of all micro-optical elements provides a micro-optical function that is separate from and in addition to the macro-optical function of the second lens 20. Thus, the total optical function of the second lens 20 is the addition of its macro-optical function and its micro-optical function, respectively, provided by the macro-optical and micro-optical components 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 its macro-optical design, i.e., without any overall optical power over most or all of the useful 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, i.e., without any micro-optical elements.

[0065] The arrangement 11 of micro-optical elements 1 of the first lens 10 has features, and the arrangement 21 of micro-optical elements of the second lens 20 has features.

[0066] Typically, the micro-optical element arrangement 11 of the first lens 10 and the micro-optical element arrangement 21 of the second lens 20 have the following characteristics: - the shape of the micro-optical elements, - the density of the micro-optical elements or the number or quantity of the micro-optical elements in each arrangement of optical elements; - the diopter power of the micro-optical element, - the geometry of the micro-optical elements, - refractive, diffractive or diffusive optical functions of micro-optical elements, - the type of micro-optical element, i.e. refractive, diffractive or diffusing micro-lenses, Pi-Fresnel micro-lenses, diffraction grating monofocal, bifocal, multifocal micro-lenses, scattering dots, Fresnel structures or toroidal structures, - focal length of micro-optical elements, - the size or diameter of the micro-optical element, - the position of the arrangement of micro-optical elements in the field of view of the first lens and the second lens, - the position of the micro-optical elements in each arrangement of the micro-optical elements; - Geometric or random structure of each arrangement of micro-optical elements Depends on.

[0067] For this purpose, the aforementioned characteristics include the optical characteristics of the micro-optical elements, which typically include at least one of the following parameters: dioptric power, refractive, diffractive or diffractive optical function, focal length, diameter, and geometric shape of the micro-optical element.

[0068] In the present disclosure, each micro-optical element belonging to the first lens 10 arrangement 11 or the second lens 20 arrangement has a size and surface shape comprised between 0.1 and 2.5 millimeters, for example a spherical, aspherical or toroidal surface shape.

[0069] Each micro-optical element provides a refractive, diffractive or diffusing function.

[0070] In one embodiment, some or all of the micro-optical elements of the first lens 10 arrangement 11 or the second lens 20 arrangement 21 are refractive micro-optical elements. Each refractive micro-optical element of the first lens 10 arrangement 11 or the second lens 20 arrangement 21 may include a monofocal or bifocal spherical dioptric power.

[0071] The refractive micro-optical element can be a monofocal or bifocal micro-optical element.

[0072] For example, refractive micro-optical elements include refractive bifocal micro-optical elements having spherical or aspherical shapes.

[0073] The diffractive micro-optical element includes, for example, a diffractive pi Fresnel micro-optical element. The diffractive pi Fresnel micro-optical element has a phase function that exhibits a π phase jump at a nominal wavelength λ, which is considered to be 550 nm for human eye vision applications. The diffractive pi Fresnel micro-optical element exhibits an optical axis that is perpendicular to its surface and passes through the optical center of the micro-optical element. A micro-optical element arrangement including a diffractive pi Fresnel micro-optical element diffracts light primarily in two diffraction orders associated with two diopter powers, P(λ) and P(λ). Thus, when receiving collimated light, the micro-optical element concentrates the light into two distinct regions on their axes. Typically, the diopter power P(λ) may have a spherical or aspherical function for the "+1" diffraction order, and the diopter power P(λ) may have a spherical or aspherical function for the zero diffraction order.

[0074] For example, the diopter power P0(λ0) is included within a range of + / −0.12 diopters in addition to the spherical power of the given refractive power of the first or second lens, derived for example from the wearer's prescription.

[0075] According to one embodiment, the diopter power P1(λ0) is comprised in absolute values ​​between 1 diopter and 10 diopters. Preferably, the diopter power P1(λ0) is comprised between ±2 diopters and ±6 diopters.

[0076] A diffusive micro-optical element has a diffusive optical function. This means that the diffusive optical element is configured to scatter light. For example, collimated light is scattered in a cone with an apex angle ranging from + / -1° to + / -40°. In one example, the diffusive micro-optical element is positioned to scatter light locally, i.e., at the intersection between a given micro-optical element and the wavefront reaching the given micro-optical element. A micro-optical element with a diffusive optical function can be similar to the micro-optical element described in U.S. Pat. No. 10,302,962.

[0077] In the example shown in FIG. 11, the micro-optical elements of the first lens 10 or the second lens 20 are arranged on the front surface F1 of the first optical lens 10 or the second optical lens 20.

[0078] Alternatively, at least some or all of the micro-optical elements of the first lens 10 or the second lens 20 are arranged on the rear surface F2 of the first lens 10 or the second lens 20, or on both the front surface 11 and the rear surface 12 of the first lens 10 or the second lens 20.

[0079] Alternatively, all or part of the micro-optical elements of the first lens 10 or the second lens 20 are embedded in the thickness of the first lens 10 or the second lens 20 between its front and rear surfaces.

[0080] Further alternatively, at least some or all of the micro-optical elements of the first lens 10 or the second lens 20 are formed on a film in the form of patches deposited on at least one of the front and rear surfaces of the first lens 10 or the second lens 20.

[0081] In a variant, at least some or all of the micro-optical elements are formed by lamination onto at least one of the front and rear faces of the first or second lens 10,20.

[0082] In practice, the micro-optical elements are formed either as a single integral part with the rest of the first lens 10 or second lens 20 (typically by injection molding, press molding, rolling or machining), or alternatively on a film (forming a patch or laminate) applied to one or both of the front surface 11 and back surface 12 of the first lens 10 or second lens 20.

[0083] In the following, the expression "zone" of a lens refers to an area of ​​a first or second optical lens that is defined in the same projection plane (i.e., the plane of Figures 1 to 10). Consequently, when comparing a zone of a first optical lens 10 with a zone of a second optical lens 20, the two zones are defined in the same projection plane. By projection plane is meant a flat, planar surface of the first lens 10 or the second lens 20, without taking into account the curvature of this considered lens.

[0084] In a non-limiting example, the micro-optical element arrangement 11 of the first lens 10 has features that provide a first myopic progression control function to a first eye of the wearer. Typically, the first myopic progression control function is achieved by a micro-optical function of the micro-optical components of the first lens 10. The micro-optical element arrangement 21 of the second lens 20 has features that provide a second myopic progression control function to a second eye of the wearer. Typically, the second myopic progression control function is achieved by a micro-optical function of the micro-optical components of the second lens 20. In other words, the micro-optical elements of the first lens 10 and the micro-optical elements of the second lens 20 have respective features adapted to control the progression of myopia.

[0085] For this purpose, the arrangement of micro-optical elements of the first lens 10 is adapted to provide a particular spatial distribution of blur, and the micro-optical elements of the second lens 20 have characteristics adapted to provide another different spatial distribution, also called the defocus effect. Thus, the arrangement of micro-optical elements 11 of the first lens 10 has characteristics providing a first defocus spatial function, and the arrangement of micro-optical elements 21 of the second lens 20 has characteristics providing a second defocus spatial function. In an exemplary embodiment, the micro-optical elements include micro-lenses providing refractive power.

[0086] In a variant, the micro-optical elements provide a diffractive or diffusive optical function. When the micro-optical elements provide a diffusive optical function, light incident on the wearer's eye is scattered (e.g., unfocused).

[0087] Due to the first and second propagation control functions, the light beam (composed of light rays) passing through the first lens 10 and the second lens 20 respectively is divided into two parts: a first portion corresponding to light rays deflected by the macro-optical components of a given lens (first lens 10 or second lens 20) and not affected by the arrangement of micro-optical elements. Typically, the first portion corresponds to light rays that do not pass through one of the micro-optical elements of the arrangement of micro-optical elements; - a second part corresponding to the light rays affected by the micro-optical components (i.e. the arrangement of micro-optical elements) and macro-optical components of a given lens; It can be divided into:

[0088] Typically, the second portion of the light beam is referred to as a myopia control signal, which can be quantified by a light intensity, hereinafter referred to as the intensity of the myopia control signal.

[0089] The myopia control signal depends on the characteristics of the micro-optical element, here based on a given myopic progression control function (first or second myopic progression control function). Typically, the myopia control signal depends on the refractive, diffractive or diffusive optical function of the micro-optical element. For this purpose, the myopia control signal is as follows: - Diffuse signal, if the micro-optical element has a diffusing function. As explained above, a diffusive signal corresponds to an unfocused signal, typically a scattered signal. - Diffraction signals, if the micro-optical elements have a diffusing function. As explained above, the diffraction signals correspond to unfocused signals, typically scattered signals. - a refraction signal, if the micro-optical element has a diffusion function (a defocus effect via a given defocus spatial function). The refraction signal corresponds to a focusing signal. Typically, in this case, light rays entering the wearer's eye are imaged in front of the retinal surface onto a poorly focused plane located in front of the retinal surface. In contrast, for a first portion of the light rays, the macro-optical function of a given lens, which provides the prescribed refractive power for the refractive correction of a given eye, images the light rays entering the eye onto the retinal surface of the eye.

[0090] 1, the first lens 10 comprises a central zone 12 bounded by a circular contour 31. In this example, the central zone 12 of the first lens 10 is free of any micro-optical elements and has a circular shape with a radius of, for example, 4 millimeters (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).

[0091] The second optical lens 20 comprises a central zone 22 bounded by a circular contour 41. In this example, the central zone 22 of the second lens 20 is free of any micro-optical elements and has a circular shape with a radius of, for example, 4 millimeters (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).

[0092] The central zone 12, 22, which does not contain any optical elements, is configured to maximize the wearer's vision in this zone, as this zone does not contain any micro-optical elements.

[0093] Of course, in other embodiments, the central zone 12 of the first lens 10 and / or the central zone of the second lens 20 may have a different shape, for example a hexagonal, or elliptical, or octagonal, or triangular, or polygonal or asymmetrical shape, and a different size, for example a lateral size or diameter comprised between 2 mm and 6 mm.

[0094] The first lens 10 further comprises a first peripheral zone 13 arranged around the central zone 12 of the first lens 10. The first peripheral zone 13 is bounded internally by an inner contour that coincides with the outer contour 31 of the central zone 12 and externally by an outer contour 32. In the example of Figure 1, the arrangement 11 of micro-optical elements of the first lens 10 is arranged on the first peripheral zone 13 of the first lens 10.

[0095] The first lens 10 further comprises a second peripheral zone 18 disposed around the first peripheral zone 13. The second peripheral zone 18 is bounded internally by an inner contour that coincides with the outer contour 32 of the first peripheral zone 13, and externally by an outer contour 33 that coincides with the outer edge 33 of the first lens 10.

[0096] The central zone 12, the first peripheral zone 13 and the second peripheral zone 18 are concentric.

[0097] The second lens 20 further comprises a first peripheral zone 23 arranged around the central zone 22 of the second lens 20. The first peripheral zone 23 is bounded internally by an inner contour that coincides with the outer contour 41 of the central zone 22 and externally by an outer contour 42. In the example of Figure 1, the arrangement 21 of micro-optical elements of the second lens 20 is arranged on the first peripheral zone 23 of the second lens 20.

[0098] The second lens 20 further comprises a second peripheral zone 28 disposed around the first peripheral zone 23. The second peripheral zone 28 is bounded internally by an inner contour that coincides with the outer contour 42 of the first peripheral zone 23, and externally by an outer contour 43 that coincides with the outer edge 43 of the second lens 20.

[0099] The central zone 22, the first peripheral zone 23, and the second peripheral zone 28 are concentric.

[0100] By first peripheral zone is meant a specific area of ​​the first lens 10 or the second lens 20 .

[0101] The second peripheral zone refers to a specific area of ​​the first lens 10 or the second lens 20 that is arranged to be fixed to the spectacle lens frame 70. The second peripheral zone does not have any optical elements.

[0102] In the example of FIG. 1, the first peripheral zone 13 of the first lens 10 has the same size as the first peripheral zone 23 of the second lens 20 .

[0103] In this embodiment, the first peripheral zone 13 of the first lens 10 is symmetrical to the first peripheral zone 23 of the second lens 20 with respect to the sagittal plane 30 of the pair of spectacle lenses 100 .

[0104] The sagittal plane 30 is perpendicular to the projection plane (the plane of Figures 1, 7, 8, and 10). When the first lens 10 and the second lens 20 are attached to a frame 70 worn by a wearer under standard wearing conditions, the sagittal plane 30 is located in the wearer's sagittal plane. The wearer's sagittal plane is a physiological plane. The wearer's sagittal plane corresponds to the vertical median plane of the wearer's head. The wearer's sagittal plane is a plane perpendicular to the Frankfurt plane passing through the centers of rotation of the first eye and the second eye (right eye and left eye). Here, the wearer's sagittal plane passes through the centers of rotation of both of the wearer's eyes and is perpendicular to the segment passing through the center of this segment. The wearer's sagittal plane is vertical when the wearer holds their head in a straight position.

[0105] The arrangement 11 of the micro-optical elements of the first lens 10, which in this example is arranged in the first peripheral zone 13 of the first lens 10, is different from the arrangement 21 of the micro-optical elements of the second lens 20, which in this example is arranged in the first peripheral zone 23 of the second lens 20.

[0106] More precisely, the arrangement 11 of micro-optical elements of the first lens 10 and the arrangement 21 of micro-optical elements of the second lens 20 are asymmetric with respect to the sagittal plane 30 of the pair of spectacle lenses 100 .

[0107] Asymmetric means that the arrangement of micro-optical elements of the first lens is different from the arrangement of micro-optical elements 21 of the second lens 20. This means that the characteristics of the arrangement of micro-optical elements 11 of the first lens 10 are different from the characteristics of the arrangement of micro-optical elements 21 of the second lens 20.

[0108] According to the present disclosure, the micro-optical element arrangement 11 of the first lens 10 is configured to have a similar arrangement 21 of the micro-optical elements of the second lens 20 to the following parameters: - the shape of the micro-optical elements, - the density of the micro-optical elements or the number or quantity of the micro-optical elements in each arrangement of optical elements; - the diopter power of the micro-optical element, - the geometry of the micro-optical elements, - refractive, diffractive or diffusive optical functions of micro-optical elements, - type of micro-optical element, i.e. refractive, diffractive or diffusing micro-lenses, bi-Fresnel micro-lenses, diffraction gratings, bifocal, multifocal micro-lenses, scattering dots, Fresnel or toric structures, - focal length of micro-optical elements, - the size or diameter of the micro-optical element, - the position of the arrangement of micro-optical elements in the field of view of the first lens and the second lens, - the position of the micro-optical element in the arrangement of micro-optical elements; - the position of the micro-optical elements in each arrangement of the micro-optical elements; - Geometric or random structure of each arrangement of micro-optical elements differ in at least one of the following:

[0109] For example, the micro-optical elements of the first lens 10 and the second lens 20 include micro-optical elements such as micro-lenses having a disk shape. According to this embodiment, the diameter value of the micro-optical elements of the first lens 10 is 1 millimeter, and the diameter value of the micro-optical elements of the second lens 20 is 2 millimeters. The refractive power value of the micro-optical elements of the first lens 10 is +2 diopters, and the refractive power value of the micro-optical elements of the second lens 20 is +4 diopters. In addition, the number of micro-optical elements of the first lens 10 is configured to cover 60 percent of the surface of the first peripheral zone 13 of the first lens 10, and the number of micro-optical elements of the second lens 20 is configured to cover 40 percent of the surface of the first peripheral zone 23 of the second lens 20.

[0110] 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 wearer's dominant eye. Spectacle lenses according to the present disclosure are designed so that the dominant eye receives less myopia control signals than the non-dominant eye via the advancement control function (as described above) to provide maximum visual acuity for both eyes of the wearer. 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 defocus effect in the first peripheral zone 23 than the defocus effect in the first peripheral zone 23 provided by the arrangement of the micro-optical elements of the second lens 20.

[0111] The dominant eye can be assessed using processes known to those skilled in the art. For example, the dominant eye can be assessed in a binocular rivalry paradigm such as that disclosed in Qiu et al. 2020, "Binocular rivalry from luminance and contrast," Vision Research, https: / / doi.org / 10.1016 / j.visres.2020.06.006.

[0112] 2-4 show some examples of various arrangements of micro-optical elements in the first lens 10 and / or the second lens 20. It should be understood that the optical design of the lens shown in FIG. 2 can be combined with the optical design of the lens shown in FIG. 3 or 4 to form a pair of eyeglass lenses 100. The same applies to the embodiments shown in FIGS. 3 and 4.

[0113] In Fig. 2, each optical element 1 of the arrangement of micro-optical elements is adjacent to another micro-optical element of this arrangement, in other words, the micro-optical elements of the arrangement shown in Fig. 2 are in contact with each other at the level of their edges.

[0114] Such a continuous arrangement of micro-optical elements provides a higher density of micro-optical elements 1 over the first peripheral zone 13 of the first lens 10 or over the second peripheral zone 23 of the second lens 20. High density is understood to mean the coverage density, defined as the ratio between the total surface area of ​​the micro-optical elements to the surface area of ​​the lens or zone containing said arrangement of micro-optical elements. For example, the density of adjacent micro-optical elements 1 within the surface is 60 percent or more, or 80 percent or more. In this example, the density of micro-optical elements on the first peripheral zone 13, 23 is 100 percent. This means that the micro-optical elements cover the entire area of ​​the first peripheral zone 13, 23.

[0115] In another embodiment, all micro-optical elements shown in FIG. 2 are identical. This means that all micro-optical elements in the arrangement of micro-optical elements shown in FIG. 2 exhibit the same parameters. For example, the micro-optical elements shown in FIG. 2 are spherical micro-lenses, each having a diameter of, for example, 1 to 2 millimeters and a diopter power of +2 diopters. The micro-optical elements 1 shown in FIGS. 2 and 15 are preferably diffractive or refractive micro-optical elements. In the examples of FIGS. 2 and 15, the structure of the arrangement of micro-optical elements has a hexagonal pattern. Alternatively, the structure of the arrangement can have a square or rectangular pattern, as shown in FIG. 16.

[0116] The micro-optical element arrangement includes monofocal or multifocal micro-lenses, as shown in Figure 2. If the micro-optical elements are monofocal, they can have different surface shapes, i.e., spherical, aspherical, or toric.

[0117] Figure 3 shows another example of the arrangement of micro-optical elements. The micro-optical elements shown in Figure 3 have a similar shape to the micro-optical elements shown in Figure 2. In addition, the micro-optical elements shown in Figure 3 have a similar dioptric power to the micro-optical elements shown in Figure 2.

[0118] In the example of Figure 3, the micro-optical elements are not adjacent. Each optical element in the micro-optical element array has a diameter of 1 millimeter and is spaced at least 0.1 millimeters from an adjacent micro-optical element. For example, one edge of optical element 1 in the micro-optical element array is spaced 0.5 millimeters from the edge of an adjacent optical element.

[0119] For example, the density of the arrangement of micro-optical elements on the first peripheral zone 13, 23 is less than 80 percent, for example 60 percent.

[0120] With such an arrangement of the micro-optical elements, the spacing between adjacent micro-optical elements is adapted to provide a specific defocus effect. Indeed, with such an arrangement, the density of the micro-optical elements shown in FIG. 3 is lower than the density of the micro-optical elements shown in FIG. 2. This means that the defocus effect in the first peripheral zone provided by the arrangement of the micro-optical elements in FIG. 3 is lower than the defocus effect in the first peripheral zone provided by the arrangement of the micro-optical elements in FIG. 2. As a result, the visual acuity provided by the first lens 10 or the second lens 20 having the optical design shown in FIG. 3 is different from the visual acuity provided by the optical design provided in the example of FIG. 2.

[0121] In a first embodiment, the first lens 10, preferably the first peripheral zone 13 of the first lens 10, comprises the arrangement of micro-optical elements shown in Figure 2, and the second lens 20, preferably the first peripheral zone 23 of the second lens 20, comprises the arrangement of micro-optical elements shown in Figure 3. Such a design of a pair of spectacle lenses 100 makes it possible to obtain two different types of vision and defocus effects for each eye.

[0122] FIG. 4 shows another embodiment of the arrangement of the micro-optical elements of the first lens 10 or the second lens 20. In FIG.

[0123] In this example, the micro-optical element arrangement includes multiple rings of micro-optical elements, the rings having increasing diameters around a central zone. In this example, the rings of optical elements are concentric. Each ring of micro-optical elements is spaced, for example, edge-to-edge from an adjacent ring by at least 0.5 millimeters, e.g., 2 millimeters.

[0124] The ring of micro-optical elements is comprised in the first peripheral zone 13 of the first lens 10 or in the first peripheral zone 23 of the second lens 20 .

[0125] The micro-optical element density of the arrangement of micro-optical elements shown in FIG. 4 is greater than 30 percent, preferably 40 percent, on the first peripheral zone 13, 23 of the first lens 10 or second lens 20.

[0126] In a non-limiting embodiment, the first lens 10 of Figure 1 includes the arrangement of micro-optical elements shown in Figure 4, and the second lens 20 of Figure 1 includes the arrangement of micro-optical elements of Figure 2 or Figure 3. Such a design of a pair of spectacle lenses 100 makes it possible to obtain two different types of vision and defocus effects for each eye.

[0127] Figure 5 shows the modulation transfer function (MTF) of the first lens and Figure 6 shows the modulation transfer function of the second lens 20 of the pair of spectacle lenses 100 shown in Figure 1. The modulation transfer functions make it possible to evaluate the defocus effect induced by a lens with an arrangement of microlenses as a function of the spatial zone of the lens.

[0128] The modulation transfer functions in these examples are calculated over a specific zone Zo of the first lens 10 (in the case of FIG. 5) or the second lens 20 (in the case of FIG. 6). For this purpose, the zone Zo has a circular shape with a diameter comprised between 3 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 contains micro-optical elements. Typically, the density of the micro-optical elements within the zone Zo is greater than 40 percent. In the following disclosure, the modulation transfer function can be measured directly using the optical system S described in FIG. 14.

[0129] The system S comprises a light capture device C, a light emitting device I configured to generate a collimated beam of light CB, and an aperture P located on or very close to the first lens 10 or the second lens 20 and used as a stop to delimit a specific zone Zo of the first lens 10 or the second lens 20 for which the modulation transfer function is measured. Only rays of the collimated beam that pass through the aperture P reach the light capture device. Here, the aperture P is located on or in front of the front surface F1 of the first lens 10 or the second lens 20. Of course, in variants of the system S, the aperture P may also be located on the back surface F2 of the first lens 10 or the second lens 20 or behind the back surface F2 of the first lens 10 or the second lens 20.

[0130] 14, the first lens 10 or the second lens 20 is disposed between the light emitting device I and the light capturing device C. The light emitting device I, the aperture P, the first lens 10 or the second lens 20, and the light capturing device C are aligned.

[0131] The light source I is a monochromatic or polychromatic visible spectrum light source with a wavelength between 400 nm and 780 nm (λ) and a high quality factor M 2 is a laser source with a λ close to 1. Advantageously, the collimated beam emitted by the light source I has a wavelength of 540-560 nm, preferably 550 nm.

[0132] A collimated beam CB is generated by the light-emitting device I along an axis A that is nominally perpendicular to a plane normal to the surface of the first lens 10 or the second lens 20, and is centered at the center of a particular zone Zo of the first lens 10 or the second lens 20. As shown in Figure 14, the collimated beam illuminates the entire area of ​​the particular portion Zo of the first lens 10 or the second lens 20.

[0133] In FIG. 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 to measure the modulation transfer functions on different parts of the first lens 10 and the second lens 20.

[0134] Since the first lens 10 or the second lens 20 is illuminated by a collimated beam, the distance between the light-emitting device I and the first lens 10 or the second lens 20 can be changed without substantially changing the determined modulation transfer function.

[0135] The light capture device C includes at least a lens L and an image sensor Sb. The position of the lens L and the position of the sensor Sb can be adjusted to take into account different analytical planes, for example, to scan the first lens 10 or the second lens 20 along the axis z1 or z2.

[0136] The sensor Sb is configured to capture an image obtained by a collimated light 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 modulation transfer function of the zone Zo of the first lens 10 or the second lens 20 can be determined by calculating the point spread function (PSF) and then the Fourier transform of the point spread function.

[0137] In another embodiment, the modulation transfer function of the zone Zo of the first lens 10 or the second lens 20 is determined by measuring the surface relief of the surface of the first lens 10 or the second lens 20 that includes the micro-optical elements, the front surface F1 of the lens under consideration. Typically, the surface relief of the surface can be determined using an interferometer. The difference in the optical path length of two points belonging to the zone Zo is determined. For this purpose, the difference in the surface relief of two different points of the zone 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 features). In a variant, the point spread function can be calculated at different planes of the given lens, and then the modulation transfer function can be calculated.

[0138] In a variant, a simulated modulation transfer function is calculated, in which case a specific zone Zo of a given lens is selected by a simulated aperture P' (i.e., diaphragm) placed 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 in the direction of central gaze, defined by two angles (αC, βC) shown in Figure 12.

[0139] With regard to the method described above, by spatially scanning the field of view of the first lens 10 or the second lens 20 using simulated apertures P' or projections P' defined for several central gaze directions, it is possible to calculate the modulation transfer function on different specific zones Zo of the simulated first lens 10 or the second lens 20, thereby making it possible to measure the modulation transfer function for different eccentricities of the visual gaze direction.

[0140] A point spread function (PSF) is calculated, giving the degree of spread (blurring) of the image of a point object over the considered portion Zo of the first lens 10 or the second lens. The point spread function is a function of the ophthalmic lens center V10, V20 of the first or second lens 10, 20, typically an ideal Gaussian (M 2 The point spread function is calculated by simulations known to those skilled in the art using a point source emitting in the monochromatic or polychromatic visible spectrum from 400 nm to 780 nm (λ) in the form (λ = 1). For each wavelength λ, the point spread function is calculated as the squared magnitude (x 1;2 , y 1;2 ) to P'(x 1;2 , y 1;2 )=A(x 1;2 , y 1;2 )exp(ikW(x 1;2 , y 1;2 )), where k is the wavenumber (2π / λ), λ is the wavelength of the point source, preferably equal to 550 nm, and A(x 1;2 , y 1、2 ) is the apodization function, which may be equal to 1, and W(x 1;2 , y 1;2 ) corresponds to the difference in optical path length provided by the first lens 10 or the second lens 20. The modulation transfer function is then calculated based on the Fourier transform of the calculated point spread function.

[0141] In the examples of Figures 5 and 6, the modulation transfer function is calculated for a wavelength of 550 nm for a zone Zo of 4 mm diameter and a gaze direction (α) which exhibits a decentration of 6.6 mm relative to the ophthalmic lens center V10 of the first lens 10 in the example shown in Figure 5 or the ophthalmic lens center V20 of the second lens 20 in the example shown in Figure 6. c , β c ) is calculated or measured. In the present disclosure, the expression decentration refers to the distance between the ophthalmic lens center V10, V20 of the considered lens and the point on the given lens corresponding to the center of the zone Zo. In another embodiment, the modulation transfer function can be estimated for different eccentricities, for example, for eccentricities comprised between 4 mm and 26 mm when the central zone 12, 22 of the first or second lens does not have any micro-optical elements. When the central zone 12, 22 of the first or second lens contains micro-optical elements, the modulation transfer function can further be estimated for lower eccentricities, for example, for those comprised between 0 (in the central gaze direction) and 4 mm.

[0142] FIG. 5 shows the horizontal profile of the modulation transfer function of the first lens 10 and the vertical profile of the modulation transfer function of the first lens 10. In FIG.

[0143] In this example, the first lens 10 has a series of micro-optical elements as shown in Figure 2. In this embodiment, the micro-optical elements may be, for example, Pi-Fresnel micro-optical elements having a diameter of 2 millimeters and a diopter power between 0 and 10 diopters. Preferably, in this example, the Pi-Fresnel micro-optical elements of the first lens 10 have a diopter power P0(λ0) equal to 0 diopters and a diopter power P1(λ0) equal to 4 diopters.

[0144] In this disclosure, the horizontal axis profile of the modulation transfer function corresponds to the variation of the estimated or calculated modulation transfer function along the horizontal axis x1 of the first lens 10 or along the horizontal axis x2 of the second lens 20, respectively. Hereinafter, this profile will be referred to as the horizontal modulation transfer function. The horizontal modulation transfer function corresponds to the cross-section of the Fourier transform of the point spread function along the horizontal axis x1 of the first lens 10 or along the horizontal axis x2 of the second lens 20. In contrast, the vertical axis profile of the modulation transfer function corresponds to the variation of the calculated or estimated modulation transfer function along the vertical axis y1 of the first lens 10 or along the vertical axis y2 of the second lens 20, respectively. Hereinafter, this profile will be referred to as the vertical modulation transfer function. The vertical modulation transfer function corresponds to the cross-section of the Fourier transform of the point spread function along the vertical axis y1 of the first lens 10 or along the vertical axis y2 of the second lens 20, respectively.

[0145] In Figure 5, the vertical modulation transfer function and the horizontal transfer function follow the same variation and 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 the horizontal axis x1. Therefore, in the example shown in Figure 5, this disclosure uses the term modulation transfer function only when talking about the vertical and horizontal modulation transfer functions.

[0146] According to this embodiment, the modulation transfer function exhibits values ​​of 0.60, 0.65, 0.70, 0.75, 0.80, 0.85, 0.90, 0.95 (au) or greater over a range of spatial frequencies comprised between 0 and 7 cycles per degree, preferably between 0 and 5 cycles per degree.

[0147] 5, the modulation transfer function of the first lens 10 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 embodiment, the modulation transfer function reaches a minimum value of 51 (au) over a spatial frequency range between 3 and 5 cycles per degree.

[0148] The modulation transfer function exhibits values ​​of 0.50, 0.45, 0.40, and 0.35 (au) over a range of spatial frequencies comprised between 2 and 7 cycles per degree.

[0149] Additionally, the modulation transfer function of the first lens 10 exhibits attenuation at spatial frequencies between 4 and 5 cycles per degree. Then, for spatial frequencies between 6 and 12 cycles per degree, the modulation transfer function exhibits values ​​greater than 0.4, preferably greater than 0.35. Thus, the modulation transfer function over the range of spatial frequencies between 6 and 11 cycles per degree exhibits a spike 52. For this range of spatial frequencies, the modulation transfer function reaches a maximum value 53 for a spatial frequency equal to 9 cycles per degree. Then, the modulation transfer function of FIG. 5 decreases after the maximum value 53 for spatial frequencies greater than 9 cycles per degree.

[0150] The modulation transfer function exhibits values ​​of 0.30, 0.35, 0.40, and greater than 0.41 over a range of spatial frequencies comprised between 6 and 12 cycles per degree.

[0151] The first lens 10 provides good visual performance for mid-spatial frequencies, especially those between 5 and 10 cycles per degree.

[0152] FIG. 6 shows a horizontal profile 63 of the modulation transfer function of the second lens 20 and a vertical profile 64 of the modulation transfer function of the second lens 20 .

[0153] The second lens 20 of an embodiment of a pair of eyeglass lenses 100 includes an arrangement of micro-optical elements exhibiting characteristics (parameters) that vary with each of the four 45-degree quadrants, as shown, for example, in Figure 10. In this embodiment, the micro-optical elements are single-focus, contiguous micro-optical elements having a diameter of 0.6 millimeters and a diopter power of 3.5 to 6 diopters.

[0154] In this example, the horizontal axis profile 63 of the modulation transfer function of the second lens 20 and the vertical axis profile 64 of the modulation transfer function of the second lens 20 are plotted for apertures P′, P of 4 mm diameter and a gaze direction (α ) exhibiting a decentration of 6.6 mm (relative to the ophthalmic lens center V20 of the second lens 20).c , β c ) is estimated or calculated for

[0155] 6, the vertical modulation transfer function and the horizontal transfer function do not follow the same variations, which means that the optical design of the second lens 20 provides different optical functions along the vertical axis y2 and the horizontal axis x2.

[0156] In Figure 6, the horizontal modulation transfer function 63 exhibits multiple spikes and multiple valleys. Specifically, the horizontal modulation transfer function 63 in Figure 6 is as follows: - maximum value 65a with a value higher than 0.9 at a spatial frequency of 0 cycles per degree, - maximum value 65b, with values ​​comprised between 0.85 and 0.75 for spatial frequencies comprised between 18 and 21 cycles per degree; - maximum value 65c, with values ​​comprised between 0.65 and 0.55 for spatial frequencies comprised between 35 and 42 cycles per degree; - Maximum value of 65d with a value between 0.50 and 0.40 for spatial frequencies between 54 and 57 cycles per degree to reach.

[0157] The horizontal modulation transfer function 63 exhibits a value of 0.33 or greater over a range of spatial frequencies comprised between 18 and 21 cycles per degree, a value of 0.3 or greater over a range of spatial frequencies comprised between 35 and 42 cycles per degree, and a value of 0.2 or greater over a range of spatial frequencies comprised between 54 and 57 cycles per degree. Preferably, the maximum value 65 of the horizontal transfer function 63 is 0.6 or greater over a range of spatial frequencies comprised between 18 and 21 cycles per degree, the maximum value 65 of the horizontal transfer function 63 is 0.5 or greater over a range of spatial frequencies comprised between 35 and 42 cycles per degree, and the maximum value 65 of the horizontal transfer function 63 is 0.35 or greater over a range of spatial frequencies comprised between 54 and 57 cycles per degree.

[0158] The horizontal modulation transfer function 63 exhibits values ​​of 0.60, 0.65, 0.70, 0.75, 0.80, 0.85, 0.90, 0.95 or greater over a range of spatial frequencies comprised between 0 and 7 cycles per degree, preferably between 0 and 5 cycles per degree.

[0159] The horizontal modulation transfer function exhibits values ​​of 0.60, 0.65, 0.70, 0.75, 0.80, or greater over a spatial frequency range of 15 to 23 cycles per degree. Additionally, according to this embodiment, the horizontal modulation transfer function 63 exhibits values ​​of 0.40, 0.45, 0.50, 0.55, 0.60, or greater over a spatial frequency range of 33 to 43 cycles per degree. The horizontal modulation transfer function 63 then exhibits values ​​of 0.30, 0.35, 0.40, 0.42, or greater over a spatial frequency range of 53 to 57 cycles per degree.

[0160] Additionally, in the example of Figure 6, the horizontal modulation transfer function 63 is attenuated at around 10 cycles per degree, 28 cycles per degree, and 47 cycles per degree. Preferably, the horizontal modulation transfer function 63 of Figure 6 is attenuated at around 10 cycles per degree, 28 cycles per degree, and 47 cycles per degree. - minimum value 67a, with values ​​between 0.40 and 0.30 for spatial frequencies between 8 and 12 cycles per degree; - minimum value 67b with values ​​between 0.30 and 0.20 for spatial frequencies comprised between 25 and 32 cycles per degree; - Minimum value 67c with a value between 0.25 and 0.15 for spatial frequencies between 41 and 52 cycles per degree to reach.

[0161] The horizontal modulation transfer function 63 exhibits a value of 0.5 or less, preferably 0.4 or less, over the range of spatial frequencies comprised between 8 and 12 cycles per degree, a value of 0.35 or less over the range of spatial frequencies comprised between 25 and 32 cycles per degree, and a value of 0.3 or less, preferably 0.26 or less, over the range of spatial frequencies comprised between 41 and 52 cycles per degree. Preferably, the minimum value 67 of the horizontal transfer function 63 is 0.35 or less over the range of spatial frequencies comprised between 8 and 12 cycles per degree, the minimum value 67 of the horizontal transfer function 63 is 0.28 or less over the range of spatial frequencies comprised between 25 and 32 cycles per degree, and the minimum value 67 of the horizontal transfer function 63 is 0.24 or less over the range of spatial frequencies comprised between 41 and 52 cycles per degree.

[0162] According to this embodiment of the present disclosure, the horizontal modulation transfer function 63 exhibits values ​​of 0.50, 0.45, 0.40, 0.35, or less over a range of spatial frequencies comprised between 6 and 12 cycles per degree, preferably between 8 and 12 cycles per degree. Additionally, the horizontal modulation transfer function 63 exhibits values ​​of 0.45, 0.40, 0.35, 0.30, 0.28, or less over a range of spatial frequencies comprised between 25 and 35 cycles per degree, preferably between 25 and 32 cycles per degree. Thus, the horizontal modulation transfer function 63 exhibits values ​​of 0.40, 0.35, 0.30, 0.25, 0.23, 0.20, or less over a range of spatial frequencies comprised between 41 and 54 cycles per degree, preferably between 45 and 52 cycles per degree.

[0163] In Figure 6, the vertical modulation transfer function 64 exhibits one spike and multiple valleys. Specifically, the vertical modulation transfer function 64 in Figure 6 reaches a maximum value 66 between 30 and 33 cycles per degree.

[0164] According to this embodiment, the vertical modulation transfer function 64 exhibits values ​​of 0.60, 0.65, 0.70, 0.75, 0.80, 0.85, 0.90, 0.95 or greater over a range of spatial frequencies comprised between 0 and 7 cycles per degree, preferably between 0 and 5 cycles per degree.

[0165] According to this embodiment, the vertical modulation transfer function 64 exhibits values ​​of 0.40, 0.45, 0.50, 0.55, 0.60, 0.63, 0.65 or greater over a range of spatial frequencies comprised between 28 and 38 cycles per degree, preferably between 30 and 35 cycles per degree.

[0166] Additionally, in the example of Figure 6, the vertical modulation transfer function 64 is attenuated between 10 and 26 cycles per degree, and between 40 and 60 cycles per degree. Preferably, the vertical modulation transfer function 64 of Figure 6 is attenuated between 10 and 26 cycles per degree, and between 40 and 60 cycles per degree. - minimum value 68a, with values ​​between 0.35 and 0.25 for spatial frequencies between 10 and 28 cycles per degree; - Minimum value 68b with a value between 0.25 and 0.15 for spatial frequencies between 40 and 60 cycles per degree to reach.

[0167] According to this example, the vertical modulation transfer function 64 exhibits a value of less than or equal to 0.33 over the range of spatial frequencies comprised between 10 and 26 cycles per degree, and a value of less than or equal to 0.3 over the range of spatial frequencies comprised between 10 and 26 cycles per degree.

[0168] In this embodiment, the vertical modulation transfer function 64 exhibits values ​​of 0.45, 0.40, 0.35, 0.34, 0.33, 0.32, or less over a range of spatial frequencies comprised between 6 and 28 cycles per degree, preferably between 10 and 16 cycles per degree. Accordingly, the vertical modulation transfer function 64 exhibits values ​​of 0.35, 0.30, 0.25, 0.20, 0.19, 0.18, or less over a range of spatial frequencies comprised between 37 and 60 cycles per degree, preferably between 40 and 60 cycles per degree.

[0169] The second lens 20 exhibits a vertical modulation transfer function with peaks and valleys. Such a design provides good visual performance for high spatial frequencies, especially frequencies of 20-30 cycles per degree.

[0170] In a pair of eyeglass lenses 100 according to the present disclosure, the vertical modulation transfer function of the first lens 10 is different from the vertical modulation transfer function of the second lens 20. In addition, the horizontal modulation transfer function of the first lens 10 is different from the horizontal modulation transfer function of the second lens 20. As a result, the first lens 10 exhibits good optical performance for a particular frequency range, and the second lens 20 exhibits good optical performance for another particular frequency range.

[0171] According to this embodiment, the modulation transfer function profile of the first and second lenses 10, 20 can be adapted to the wearer's dominant eye.

[0172] For example, if a wearer's second eye is dominant and the wearer requires a pair of eyeglass lenses to read small letters, then the optical design of the second lens 20 (thanks to the micro-optical features) is selected to provide a high modulation transfer function (i.e., greater than 0.4, preferably greater than 0.5) over a range of spatial frequencies comprised between 20 and 30 cycles per degree, and a low modulation transfer function over a range of spatial frequencies comprised 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 over a range of spatial frequencies comprised between 5 and 10 cycles per degree, and a low modulation transfer function over a range of spatial frequencies comprised between 20 and 30 cycles per degree. Thus, the second lens 20 provides a different defocus effect than the first lens 10.

[0173] A second embodiment of a pair of eyeglass lenses 200 according to the present disclosure will be described with reference to FIGS.

[0174] 7 shows a pair of eyeglass lenses 200 having a first lens 10 and a second lens 20. The second lens 20 of the pair of eyeglass lenses 200 is identical to the second lens 20 included in the pair of eyeglass lenses 100. Therefore, only the differences between the pair of eyeglass lenses 100 of FIG.

[0175] In this embodiment, the central zone 12 of the first lens 10 contains micro-optical elements 1. As a result, the arrangement 11 of micro-optical elements of the first lens 10 extends over the central zone 12 of the first lens 10. This embodiment makes it possible to obtain a first lens 10 that is completely covered by the arrangement of micro-optical elements. The first lens 10 does not contain any areas without micro-optical elements. Therefore, the arrangement of micro-optical elements of the second zone 15 of the first lens 10 and the arrangement of micro-optical elements of the second zone 25 of the second lens 20 are asymmetric with respect to the sagittal plane 30 of the pair of spectacle lenses.

[0176] Preferably, the micro-optical elements 1 arranged in the central zone 11 of the first lens 10 have a similar arrangement to the micro-optical elements 1 arranged in the first peripheral zone 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 zone 12 and the first peripheral zone 13. This optical design provides a first lens 10 that is easy to manufacture and limits the cost of a pair of spectacle lenses 200. This optical design is interesting because, for example, the manufacturing process of the first lens 10 does not need to take into account the cylindrical axis in case of astigmatism correction, improving the time and ease of the manufacturing process.

[0177] A third embodiment of a pair of eyeglass lenses 300 according to the present disclosure will now be described with reference to FIGS.

[0178] 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 is free of any micro-optical elements, and the central zone 22 of the second lens 20 is free of any micro-optical elements.

[0179] In this embodiment, the first lens 10 and the second lens 20 are each divided into at least three complementary zones: a central zone 12, 22, a first zone 14, 24, and a second zone 15, 25. The first zone 14 and the second zone 15 of the first lens 10 constitute a first peripheral zone 13 of the first lens 10, and the first zone 24 and the second zone 25 of the second lens 20, respectively, constitute a first peripheral zone 23 of the second lens 20.

[0180] The first zone 14 of the first lens 10 is disposed above the secondary axis 40, the first zone 24 of the second lens 20 is disposed below the secondary axis 40, and the second zone 15 of the first lens 10 is disposed below the secondary axis 40 and the second zone 25 of the second lens 20 is disposed above the secondary axis 40. Of course, in variants, the first zone 14 of the first lens 10 can be disposed below the secondary axis 40 and the first zone 24 of the second lens 20 can be disposed above the secondary axis 40, and the second zone 15 of the first lens 10 can be disposed above the secondary axis 40 and the second zone 25 of the second lens 20 can be disposed below the secondary axis 40.

[0181] In a preferred embodiment, the first zone 14 of the first lens 10 is identical to the first zone 24 of the second lens 20, and the second zone 15 of the first lens 10 is identical to the second zone 25 of the second lens 20, respectively. To this end, the first zone 14 of the first lens 10 is symmetrical to the first zone 24 of the second lens 20 by a rotation of 180 degrees about an axis 50 perpendicular to the plane of FIG. 8, i.e. perpendicular to the mean plane of the lenses, the axis 50 lying in the sagittal plane 30 of the pair of spectacle lenses 300. Similarly, the second zone 15 of the first lens 10 is symmetrical to the second zone 25 of the second lens 20 by a rotation of 180 degrees about an axis 50 perpendicular to the plane of FIG. 8, i.e. perpendicular to the mean plane of the lenses, the axis 50 lying in the sagittal plane 30 of the pair of spectacle lenses 300. The first zone 14 and the second zone 15 of the first lens 10 each include an arrangement of micro-optical elements, and the first zone 24 and the second zone 25 of the second lens 20 each include an arrangement of micro-optical elements.

[0182] This means that the first lens 10 and the second lens 20 each have an optical design that includes a macro-optical component as described above and two micro-optical components, referred to as a first micro-optical component and a second micro-optical component, respectively.

[0183] The first micro-optical component of the first lens 10 is defined in a first zone 14 of the first lens 10, and the second micro-optical component of the first lens 10 is defined in a second zone 15 of the first lens 10. The first micro-optical component of the second lens 20 is defined in a first zone 24 of the second lens 20, and the second micro-optical component of the second lens 20 is defined in a second zone 25 of the second lens 20.

[0184] The characteristics of the micro-optical elements in the first zone 14 of the first lens 10 are different from the characteristics of the micro-optical elements in the second zone 15 of the first lens 10. For example, the number of micro-optical elements in the first zone 14 of the first lens 10 is less than the number of micro-optical elements in the second zone 15 of the first lens 10. In another example, the size of the micro-optical elements in the first zone 14 is smaller than the size of the micro-optical elements in the second zone 15 of the first lens 10.

[0185] Respectively, the characteristics of the micro-optical elements in the first zone 24 of the second lens 20 are different from the characteristics of the micro-optical elements in the second zone 25 of the second lens 20. For example, the number of micro-optical elements in the first zone 24 of the second lens 20 is less than the number of micro-optical elements in the second zone 25 of the second lens 20. In another example, the size of the micro-optical elements in the first zone 24 is smaller than the size of the micro-optical elements in the second zone 25 of the second lens 20.

[0186] In FIG. 8, the first micro-optical component of the first lens 10 is similar to the first micro-optical component of the second lens 20. To this end, it is the following: the arrangement of the micro-optical elements contained in the first zone 14 of the first lens 10 is similar to the arrangement of the micro-optical elements contained in the first zone 24 of the second lens 20; the characteristics of the micro-optical elements of the first zone 14 of the first lens 10 are similar to the characteristics of the micro-optical elements comprised in the first zone 24 of the second lens 20; means.

[0187] In other words, the arrangement of the micro-optical elements in the first zone 14 of the first lens 10 is symmetrical to the arrangement of the micro-optical elements in the first zone 24 of the second lens 20 by rotating 180 degrees around an axis 50 passing through the sagittal plane 30 and perpendicular to the mean plane of the pair of spectacle lenses.

[0188] The second micro-optical component of the first lens 10 is similar to the second micro-optical component of the second lens 20. To this end, it is: the arrangement of the micro-optical elements contained in the second zone 15 of the first lens 10 is identical to the arrangement of the micro-optical elements contained in the second zone 25 of the second lens 20; the characteristics of the micro-optical elements of the second zone 15 of the first lens 10 are similar to the characteristics of the micro-optical elements comprised in the second zone 25 of the second lens 20; means.

[0189] In other words, the arrangement of the micro-optical elements in the second zone 15 of the first lens 10 is symmetrical 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 mean plane of the pair of spectacle lenses.

[0190] This embodiment provides a pair of eyeglass lenses 300 that is easy to manufacture because the first lens 10 is similar to the second lens 20, with the second lens 20 rotated 180 degrees about the axis 50.

[0191] However, the arrangement of the micro-optical elements in the first zone 14 of the first lens 10 exhibits differences in said characteristics compared to the arrangement of the micro-optical elements in the second zone 25 of the second lens 20. Similarly, the arrangement of the micro-optical elements in the second zone 15 of the first lens 10 exhibits differences in said characteristics compared to the arrangement of the micro-optical elements in the first zone 24 of the second lens 20.

[0192] 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 eyeglass lenses 100.

[0193] 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 eyeglass lenses 100.

[0194] In this example, the micro-optical features of the first zone 14 of the first lens 10 and the second zone 14 of each second lens 20, and the micro-optical features of the second zone 15 of the first lens 10 and the second zone 25 of each second lens 20, are each adapted to control myopia progression. Typically, the features of the first zone 14 of the first lens 10 provide a first myopic progression control function for a first eye of the wearer, and the features of the second zone 15 of the first lens 10 provide a second myopic progression control function for the first eye of the wearer. The features of the first zone 24 of the second lens 20 provide a first myopic progression control function for a second eye of the wearer, and the features of the second zone 25 of the second lens 20 provide a second myopic progression control function for the second eye of the wearer.

[0195] For this purpose, the strength of the myopia control signal provided by the myopic second progression control function of the micro-optical elements in the second zone 15 of the first lens 10 is greater than the strength of the myopia control signal provided by the myopic first progression 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 power of the micro-optical elements. Similarly, the strength of the myopia control signal provided by the myopic second progression control function of the micro-optical elements in the second zone 25 of the second lens 20 is greater than the strength of the myopia control signal provided by the myopic first progression control function of the micro-optical elements in the first zone 24 of the second lens 20. As a result, good vision is provided to the eye positioned on the side of the first lens 10 (i.e., the first eye) in the upper half of the first lens 10, ensuring good vision performance for this eye, while providing a defocus effect or a diffusing optical function to the other eye (i.e., the second eye). In contrast, the other eye positioned on the side of the second lens 20 in the lower half of the second lens 20 is provided with good vision, providing a defocusing effect or diffusing optical function to the first eye while ensuring good vision performance for the other eye.

[0196] According to this example, the characteristics (or parameters) of the first zone 14, the first lens 10 and the second zone 25 of the second lens 20 may be selected to provide good vision performance when the wearer is looking at objects located far away from them (i.e., objects located, for example, more than 5 meters from the wearer's eyes). Thus, in this example, the first zone 14 and the second zone 25 of the first and second lenses 10, 20 may be dedicated to distance vision.

[0197] In contrast, the characteristics of the second zone 15, the first lens 10, and the first zone 24 of the second lens 20 may be selected to provide good vision performance when the wearer is viewing objects located at a close and / or intermediate distance from the wearer, for example, objects located less than 5 meters from the wearer's eyes. Thus, the second zone 15 and the first zone 24 of the first and second lenses 10, 20 may be dedicated to near and / or intermediate vision.

[0198] This embodiment allows for taking into account the dominant eye, which may vary depending on the distance visual acuity, and is therefore configured to provide better vision for the dominant eye according to the distance visual acuity.

[0199] Fig. 9 shows an example of a pair of eyeglass lenses 400 according to the third embodiment disclosed in Fig. 8. Therefore, only the differences from the pair of eyeglass lenses 300 shown in Fig. 8 will be disclosed.

[0200] 9, the arrangement of micro-optical elements in the first zone 14 of the first lens 10 and the arrangement of micro-optical elements in the first zone 24 of the second lens 20 are made up of three arcs centered on the optical centers 19, 29 of the central zones 12, 22, respectively. In this example, 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, under standard wearing conditions, when looking straight ahead at infinity.

[0201] In contrast, the arrangement of micro-optical elements in the second zone 15 of the first lens 10 and the arrangement of micro-optical elements in the second zone 25 of the second lens 20 are made up of five arcs centered on the optical centers of the central zones 19, 29, respectively.

[0202] In FIG. 9, 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 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, respectively.

[0203] In addition, 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 size (i.e., diameter) 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.

[0204] 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 millimeter, 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 millimeters.

[0205] A fourth embodiment of a pair of eyeglass lenses 500 according to the present disclosure will now be described with reference to FIG.

[0206] 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 is free of any optical elements, and the central zone 22 of the second lens 20 is free of any optical elements.

[0207] In this embodiment, the first lens 10 and the second lens 20 are each divided into five complementary zones: a central zone 12, 22, and four 45-degree quadrant zones defining first zones 14, 24, second zones 15, 25, third zones 16, 26, and fourth zones 17, 27, respectively. The first zone 14, second zone 15, third zone 16, and fourth zone 17 of the first lens 10 constitute the first peripheral zone 13 of the first lens 10, and the first zone 24, second zone 25, third zone 26, and fourth zone 27 of the second lens 20, respectively, constitute the first peripheral zone 23 of the second lens 20. Additionally, each of the four quadrants of the first lens 10 includes an arrangement of micro-optical elements, and 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 in a first peripheral zone 13 of the first lens 10, and the four quadrants of the second lens 20 are defined in a first peripheral zone 23 of the second lens 20. In this example, the first peripheral zone 13 of the first lens 10 is divided into four quadrants by two orthogonal axes, referred to as a first axis 81 and a second axis 82 of the first lens 10. The first axis 81 of the first lens 10 is tilted 45 degrees relative to the axis 40 by a 45 degree rotation (counterclockwise) about the ophthalmic lens center V10 of the first lens 10, and the second axis 82 of the first lens 10 is tilted 45 degrees relative to the axis 40 by a 45 degree rotation (clockwise) about the ophthalmic lens center V10 of the first lens 10. Similarly, the first peripheral zone 23 of the second lens 20 is divided into four quadrants by 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 tilted 45 degrees relative to the axis 40 by a 45 degree rotation (counterclockwise) about the ophthalmic lens center V20 of the second lens 20, and the second axis 92 of the second lens 20 is tilted 45 degrees relative to the axis 40 by a 45 degree rotation (clockwise) about the ophthalmic lens center V20 of the second lens 20.

[0208] In Fig. 10, the first zone 14 of the first lens and the second zone 25 of each second lens are arranged on the upper side of the first lens 10 and the second lens 20, respectively. The second zone 15 of the first lens and the first zone 24 of each second lens are arranged on the lower side of the first lens 10 and the second lens 20, respectively. The third zone 16 of the first lens 10 and the third zone 26 of each second lens 20 are arranged on the temporal side of the pair of spectacle lenses. The fourth zone 17 of the first lens 10 and the fourth zone 27 of each second lens 20 are arranged on the nasal side of the pair of spectacle lenses.

[0209] The first zone 14 of the first lens 10 is disposed above the ophthalmic lens center V10 of the first lens 10, and the second zone 15 of the first lens 10 is disposed on an axis z1 (transverse axis z i The third zone 16 of the first lens 10 is located to the right of the ocular center V10 of the first lens 10, and the fourth zone 17 of the first lens 10 is symmetrical to the third zone 16 by a 180-degree rotation about an axis z1 that passes through the ocular center V10 of the first lens 10 and the ocular rotation center of the eye covered by the first lens 10.

To this end, the first zone 14 of the first lens 10 is symmetrical to the first zone 24 of the second lens 20 by a rotation of 180 degrees about an axis 50 perpendicular to the plane of FIG. 10, i.e. perpendicular to the mean plane of the lenses, the axis 50 lying in the sagittal plane 30 of the pair of spectacle lenses 500. Similarly, the second zone 15 of the first lens 10 is symmetrical to the second zone 25 of the second lens 20 by a rotation of 180 degrees about an axis 50 perpendicular to the plane of Fig. 10.

[0216] In other words, the arrangement of the micro-optical elements in the first zone 14 of the first lens 10 is symmetrical to the arrangement of the micro-optical elements in the first zone 24 of the second lens 20 by rotating 180 degrees around an axis 50 passing through the sagittal plane 30 and perpendicular to the mean plane of the pair of spectacle lenses.

[0217] The second micro-optical component of the first lens 10 is similar to the second micro-optical component of the second lens 20. To this end, it is: the arrangement of the micro-optical elements contained in the second zone 15 of the first lens 10 is identical to the arrangement of the micro-optical elements contained in the second zone 25 of the second lens 20; the characteristics of the micro-optical elements of the second zone 15 of the first lens 10 are similar to the characteristics of the micro-optical elements comprised in the second zone 25 of the second lens 20; means.

[0218] In other words, the arrangement of the micro-optical elements in the second zone 15 of the first lens 10 is symmetrical 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 mean plane of the pair of spectacle lenses.

[0219] The third micro-optical component of the first lens 10 is similar to the third micro-optical component of the second lens 20. To this end, it is: the arrangement of the micro-optical elements contained in the third zone 16 of the first lens 10 is similar to the arrangement of the micro-optical elements contained in the third zone 26 of the second lens 20; the characteristics of the micro-optical elements in the third zone 16 of the first lens 10 are similar to the characteristics of the micro-optical elements contained in the third zone 26 of the second lens 20; means.

[0220] In other words, the arrangement of the micro-optical elements in the third zone 16 of the first lens 10 is symmetrical 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 mean plane of the pair of spectacle lenses.

[0221] The fourth micro-optical component of the first lens 10 is similar to the fourth micro-optical component of the second lens 20. To this end, it is: the arrangement of the micro-optical elements contained in the fourth zone 17 of the first lens 10 is identical to the arrangement of the micro-optical elements contained in the fourth zone 27 of the second lens 20; the characteristics of the micro-optical elements in the fourth zone 17 of the first lens 10 are similar to the characteristics of the micro-optical elements contained in the fourth zone 27 of the second lens 20; means.

[0222] In other words, the arrangement of the micro-optical elements in the second, fourth, and fourth zones 17 of the first lens 10 is symmetrical 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 mean plane of the pair of spectacle lenses.

[0223] The characteristics of the micro-optical elements in the first zone 14 of the first lens 10 are different from the characteristics of the micro-optical elements in the second zone 15 of the first lens 10, the characteristics of the optical elements in the third zone 16 of the first lens 10, and the characteristics of the micro-optical elements in the fourth zone 17 of the second lens 20.

[0224] The characteristics of the micro-optical elements in the first zone 24 of the second lens 20 are different from the characteristics of the micro-optical elements in the second zone 25 of the second lens 20, the characteristics of the micro-optical elements in the third zone 26 of the second lens 20, and the characteristics of the micro-optical elements in the fourth zone 27 of the second lens 20, respectively.

[0225] In other words, it is: 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, 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; means.

[0226] In FIG. 10, the features of the micro-optical elements in the first zones 14, 24 of the first lens 10 and the second lens 20, the features of the micro-optical elements in the second zones 15, 25 of the first lens 10 and the second lens 20, the features of the micro-optical elements in the third zones 16, 26 of the first lens 10 and the second lens 20, and the features of the micro-optical elements in the fourth zones 17, 27 of the first lens 10 and the second lens 20 are each adapted to control the progression of myopia.

[0227] Typically, the features of the first zone 14 of the first lens 10 provide a first myopic progression control function for the first eye of the wearer, the features of the second zone 15 of the first lens 10 provide a second myopic progression control function for the first eye of the wearer, the features of the third zone 16 of the first lens 10 provide a third myopic progression control function for the first eye of the wearer, and the features of the fourth zone 17 of the first lens 10 provide a fourth myopic progression control function for the first eye of the wearer.

[0228] Similarly, the features of the first zone 24 of the second lens 20 provide a first myopic progression control function for the wearer's second eye, the features of the second zone 25 of the second lens 20 provide a second myopic progression control function for the wearer's second eye, the features of the third zone 26 of the second lens 20 provide a third myopic progression control function for the wearer's second eye, and the features of the fourth zone 27 of the second lens 20 provide a fourth myopic progression control function for the wearer's second eye.

[0229] For this purpose, the strength of the myopia control signal provided by the second myopic progression control function of the micro-optical elements of the second zone 15 of the first lens 10 is greater than the strength of the myopia control signal provided by the first myopic progression control function of the micro-optical elements of 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 power of the micro-optical elements.

[0230] In this example, the micro-optical elements of the third zone 16 have characteristics identical to the characteristics of the micro-optical elements of the fourth zone 17 of the first lens 10. Due to such characteristics, the arrangement of the micro-optical elements of the third and fourth zones 16, 17 is similar, allowing for an easier manufacturing process for the pair of spectacle lenses 500. In addition, the strength of the myopia control signals provided by the third and fourth myopic progression control functions of the micro-optical elements of the third and fourth zones 16, 17 of the first lens 10 is greater than the strength of the myopia control signal provided by the first myopic progression control function of the micro-optical elements of the first zone 14 of the first lens 10, for example. This is achieved, for example, by differences in the density and / or size and / or diopter power of the micro-optical elements.

[0231] The strength of the myopia control signals provided by the third and fourth myopic progression control functions of the micro-optical elements in the third and fourth zones 16, 17 of the first lens 10 is respectively lower than the strength of the myopia control signal provided by the second myopic progression 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 power of the micro-optical elements.

[0232] As a result, good visual acuity is provided for the quadrant of the first lens 10 relative to the first zone 14 of the first lens 10, ensuring good visual performance, for example, when the wearer is looking at an object located far away from them (i.e., an object located more than 5 meters from the wearer's eye). Thus, the first portion 14 of the first lens 10 may be dedicated to distance vision. Conversely, the second zone 15 of the first lens 10 may be dedicated to myopia progression control growth, as may the third and fourth zones 16 and 17 of the first lens 10.

[0233] In this example, the micro-optical elements of the third zone 26 may have characteristics identical to those of the micro-optical elements of the fourth zone 27 of the second lens 20. Such characteristics result in a similar arrangement of the micro-optical elements of the third and fourth zones 26, 27. Additionally, the strength of the myopic control signals provided by the third and fourth myopic progression control functions of the micro-optical elements of the third and fourth zones 26, 27 of the second lens 20 is greater than the strength of the myopic control signal provided by the second myopic progression control function of the micro-optical elements of the first zone 24 of the second lens 20. This may be achieved, for example, by differences in the density and / or size and / or diopter power of the micro-optical elements.

[0234] The strength of the myopic control signals provided by the third and fourth myopic progression control functions of the micro-optical elements of the third and fourth zones 26, 27 of the second lens 20 is then respectively lower than the strength of the myopic control signal provided by the second myopic progression control function of the micro-optical elements of 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 power of the micro-optical elements.

[0235] As a result, good visual acuity is provided for the quadrant of the second lens 20 relative to the first zone 24 of the second lens 20, enabling good visual performance to be ensured, for example, when the wearer is viewing objects located at close and / or intermediate distances from the wearer (i.e., objects located less than 5 meters from the wearer's eyes). Thus, the first portion 24 of the second lens 20 may be dedicated to near and / or intermediate vision. Conversely, the second zone 25 of the second lens 20 may be dedicated to myopia progression control, as may the third and fourth zones 26 and 27 of the second lens 20.

[0236] Typically, the first zones 14, 24 of the first lens 10 and the second lens 20 comprise adjacent micro-optical elements (micro-lenses) each having a diameter of 1 millimeter and a diopter power between 0 and 10 diopters, preferably equal to 4 diopters.

[0237] The second zones 15, 25 of the first lens 10 and the second lens 20 comprise micro-lenses having a diameter of 1 millimeter and a diopter power of 1 to 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 from an adjacent micro-optical element by at least 0.1 millimeters, typically 1 millimeter edge-to-edge. The density of the arrangement of micro-optical elements on the second zones 15, 25 of the first lens 10 and the second lens 20 is 50 percent.

[0238] The third zones 16, 26 and fourth zones 17, 27 of the first and second lenses 10, 20 comprise micro-lenses having a diameter of 1 millimeter and a diopter power between 1 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 and second lenses 10, 20 is spaced from an adjacent micro-optical element by at least 0.1 millimeters, typically 1 millimeter edge-to-edge. The density of the micro-optical element placement across the third zones 16, 26 and fourth zones 17, 27 of the first and second lenses 10, 20 is 30 percent.

[0239] This embodiment also allows for consideration of the dominant eye, which may vary depending on distance visual acuity. Thus, the embodiment is configured to provide better vision for the dominant eye depending on distance visual acuity. The more zones defined in the optical design of the first and second lenses 10, 20, the better the correction as a function of the dominant eye.

[0240] It should be noted that, in a variant, the optical design of the first lens 10 of the pair of spectacle lenses disclosed by Figures 1 to 4 can be combined with the optical design of the second lens 20 of the pair of spectacle lenses disclosed by Figure 10, as illustrated by Figures 5 and 6. In addition, the optical design of the first lens 10 of the pair of spectacle lenses disclosed by Figures 1 to 4 can be combined with the optical design of the second lens 20 of the pair of spectacle lenses disclosed by Figures 8 to 9 to form a fifth embodiment of a pair of spectacle lenses (not shown). Similarly, the optical design of the second lens 20 of the pair of spectacle lenses disclosed by Figures 1 to 4 can be combined with the optical design of the first lens of the pair of spectacle lenses disclosed by Figures 8 to 9 or 10 to form a sixth embodiment of a pair of spectacle lenses (not shown).

[0241] Therefore, it should be understood that any optical design for a first lens 10 disclosed in the present disclosure can be combined with any optical design for a second lens 20 disclosed in the present disclosure, provided that the arrangement of the micro-optical elements of the first lens is asymmetric with the arrangement of the micro-optical elements of the second lens.
