Description

Technical Field

[0001] This invention relates to a specially distributed spectacle lens with optical enhancements to improve long-term wearing comfort and simultaneously improve perception. Background Technology

[0002] Myopia management is understood as an attempt, particularly in children and adolescents, to control the abnormal growth of the eye, which leads to severe myopia and is further exacerbated by lifestyle factors imposed by modern society (less outdoor time and more close-up work). One possible approach to controlling myopia progression is to wear special eyeglasses that attempt to shift the focal plane of peripheral vision in front of the retina, thereby slowing eye growth.

[0003] One possibility is spectacle lenses with a design similar to graduated lenses, which bring the focal plane of peripheral vision in front of the retina by increasing the effect at the periphery (e.g., US 7,025,460, EP 1 934 648 B1, WO 2017 / 222421 A1, DE 102009053467 B4). Other variations of spectacle lenses have multiple small additional acting elements (microlenses, etc.) distributed on the spectacle lens and creating a second focal plane in front of the retina (e.g., CN 104678572 B, US 10268050 B2, WO 2019 / 166653 A1, US 8950860B2, US 10901237 B2, US 11061255 B2). Another possibility is the introduction of small scatterers, which reduce peripheral contrast and thus inhibit the development of myopia (e.g., WO2018 / 026697 A1).

[0004] All these spectacle lenses share a common feature: they have a central area that provides good vision due to the prescription of the corresponding corrective effect, and a peripheral area that does not provide good vision due to myopia management measures (microlenses, effect enhancement, or scattering). The size of the central area is important for the compatibility of the spectacle, while the size and effect of the peripheral effect area are important for the success of myopia management. The ratio of these two areas is usually determined by the lens design and is the same for all corrective effects. For example, recommendations for adapting these areas to individualized eyes are described in EP 3 966 626 A1. These recommendations are based on additional measurements, either as peripheral refractive errors or with the aid of psychophysical methods.

[0005] To date, various optical effects related to the compatibility and comfort of ophthalmic lenses (especially spectacle lenses) have been examined regarding their impact on myopia and / or hyperopia, and their dependence on the development or progression of optical and physiological mechanisms aimed at explaining or slowing their development or progression (especially worsening). Existing approaches are primarily based on imaging the image in front of the retina, as this should slow eye growth. It has been confirmed that if this occurs only in the periphery of the retina, then it is sufficient (or even better).

[0006] Especially in eyeglass lenses used to correct myopia, the typical and obvious trend of myopia progression leads to a decline in the wearing comfort of the lenses after one fitting, and consequently, the satisfaction and compatibility of the eyeglasses after a short period of time. Summary of the Invention

[0007] The objective of this invention is to improve the durable compatibility of eyeglasses or eyeglass lenses, and thus achieve long-term wearing comfort in an inexpensive manner. According to the invention, this objective is achieved by the subject matter of the independent claims. Preferred embodiments are the subject matter of the dependent claims.

[0008] Therefore, in one aspect, the present invention particularly relates to an eyeglass lens comprising: a central dominant viewing region having substantially constant refractive power and preferably substantially constant image contrast; and a functional region preferably horizontally adjacent to the central dominant viewing region on both sides, the functional region having additional functional effects compared to the central dominant viewing region, the additional functional effects including at least refractive additional effects and / or contrast reduction compared to the central dominant viewing region, wherein the additional functional effects in the functional region are achieved by a combination of at least one first surface structural feature and a second surface structural feature (different from the first surface structural feature) of the eyeglass lens.

[0009] By combining the different functional effects achieved through the varying structural features of spectacle lenses used for myopia management, significant effectiveness in slowing myopia progression can be achieved while keeping the undesirable side effects of each measure relatively small. These undesirable side effects of conventional spectacle lenses used for myopia management are well-known, and have always been kept within acceptable limits by striving for a balance between effectiveness and compatibility. This is achieved here, in particular, through the appropriate distribution and characteristics of the corresponding effects.

[0010] However, by combining different effects according to the invention, this compromise can significantly improve myopia control without significantly increasing the various undesirable side effects. It is well known that spectacle lenses, similar to progressive lenses, increase peripheral effects (i.e., peripheral refractive additive effects), impair peripheral vision due to these additive effects, and have other typical disadvantages of progressive lenses (e.g., astigmatism, distortion, and flare effects). Spectacle lenses with microlenses (small lenses) particularly limit vision by reducing contrast and creating secondary images. By combining these different mechanisms of action according to the invention, they can enhance or complement each other in their role in myopia management, while each undesirable side effect can be kept relatively small. It is particularly demonstrated here that minimizing these undesirable side effects, even when multiple different side effects occur simultaneously, contributes to the compatibility of the spectacle lens. In turn, the invention thus provides the possibility of improving the effectiveness of spectacle lenses for myopia management compared to conventional lenses while maintaining compatibility.

[0011] The first and / or second surface structural features are particularly understood as a surface shape or surface function that differs from a purely or simply spherical shape or function, and preferably also differs from an astigmatic surface shape or function. In one aspect, the optical function of the first and / or second surface structural features differs from that of a purely vision-correcting surface.

[0012] Preferably, the first and / or second surface structure features include:

[0013] -Graded surface refractive power; and / or

[0014] - Microlens arrangement (microlens field); and / or

[0015] -Contrast reduced.

[0016] The gradual surface refractive power is achieved here, particularly through the continuous free-form surface of the spectacle lens, wherein the surface curvature of the anterior and / or posterior surfaces of the lens continuously varies from the central dominant visual area to, or within, the functional area, such that the functional area at least partially induces a higher refractive power than the substantially constant refractive power in the central dominant visual area, causing a portion of the light extending through the functional area to be imaged in front of the retina to counteract eye elongation. In other words, the gradual surface refractive power of the first and / or second surface structural features preferably at least partially induces a positive refractive additive effect, i.e., the surface refractive power in the functional area is preferably at least partially negatively smaller or positively larger than the refractive power in the central dominant visual area.

[0017] In particular, the first and / or second surface structural features are constructed as microstructures, especially microlenses (particularly the protrusions of the main body of the spectacle lens, also known as small lenses), such that a portion of the light passing through these microlenses (small lenses) is imaged in front of the retina to counteract eye elongation. For this purpose, the small lenses preferably have a positive refractive additional effect. Such small lenses can be either classic circular small lenses (e.g., CN 104678572 B), astigmatic structures (WO 2019 / 166653 A1), or ring structures (WO 2021 / 047488 A1), especially small lenses that have a discontinuity between the basic function and the (small) structural elements and produce a corresponding additional effect.

[0018] As another possibility for targeting the first and / or second surface structural features, contrast reduction can also preferably be achieved using spectacle lenses with scatterers (e.g., WO 2019 / 152428 A1). Contrast reduction is achieved, in particular, by using diffuse structures (light scatterers) as the first and / or second surface structural features. In one aspect, the microstructures in the functional areas at least partially contribute to the contrast reduction. For this purpose, the microstructures preferably include surface roughness that causes dimming in optical imaging. This dimming results in contrast reduction. Here, the central dominant visual area preferably remains substantially sharp, while the contrast reduction occurs only in the functional areas. This contrast reduction is beneficial because the corresponding (peripheral) visual field provides little or no stimulation for eye growth. The contrast reduction is particularly effective if the perception (or degree of perception) induced in the contrast-reduced area is in the range of at least about 0.5, preferably in the range of at least about 0.7. Preferably, the perception caused by the contrast reduction is no greater than about 0.9, and even more preferably no greater than about 0.8.

[0019] Perception here should be understood in particular as a factor of reduced vision (i.e., visual acuity), wherein, in particular, visual acuity determined to be a value of 1 according to Part 3 of DIN 58220 is assumed to be a reference. Thus, a perception of 0 (<0.1) implies essentially complete occlusion, and a perception of 1 in principle implies complete transparency. These characteristics arise particularly when spectacle lenses are arranged in a position with a typical corneal apex distance (HSA), i.e., especially when at least one value of HAS is in the range of about 11 mm to about 18 mm, and particularly preferably when at least one value of HAS is about 13 mm or about 14 mm.

[0020] Relative to the perceived value range presented herein, alternatively or additionally, it may be particularly preferred that the contrast reduction caused by the microstructure in the area of ​​action results in a haze value (especially haze percentage) according to ASTM D-1003 in the range of no more than about 10, preferably in the range of no more than about 2, and wherein preferably, the contrast reduction caused by the microstructure in the area of ​​action results in a haze value according to ASTM D-1003 in the range of at least about 0.1, especially in the range of at least about 0.5.

[0021] Particularly preferably, even with reduced contrast, the effective area still has a transmittance of at least 85, more preferably at least 90 (especially the value of luminous flux transmittance according to ASTM D-1003). This ensures that even with reduced contrast, the spectacle lens does not completely block (e.g., absorb and / or reflect) light and thus darken the field of vision; instead, light is only (partially) scattered. This largely preserves a bright impression and prevents significant pupil dilation (due to reduced light incidence).

[0022] Haze and luminous transmittance values ​​according to ASTM D-1003 can be obtained or checked, for example, using the “haze-gard plus” measuring instrument from BYK Additives and Instruments.

[0023] All combinations of the described or other schemes are feasible, among which the combination of a small lens or scatterer with a free-form surface is particularly preferred because different optical defects (on the one hand, discontinuities and non-coaxial regions, and on the other hand, large-area effect increases and distortions) affect visual perception differently.

[0024] Therefore, in a particularly preferred embodiment, the first surface structural feature includes microstructures, especially microlenses (small lenses), which cause a first positive refractive additional effect compared to the central main viewing area, wherein the second surface structural feature particularly includes a gradient surface refractive power, which causes a second positive refractive additional effect compared to the central main viewing area.

[0025] In another particularly preferred embodiment, the first surface structural feature includes an optical scatterer that causes a decrease in contrast compared to the central main viewing area, wherein the second surface structural feature includes a gradient surface refractive power that causes a second positive refractive effect compared to the central main viewing area.

[0026] In particular, it is possible to combine three different surface structure features and make them interact, or to combine multiple effects (such as microlenses and optical scatterers) into a first surface structure feature and make them interact.

[0027] The interaction between the first and second surface structural features can occur in a variety of ways. According to an embodiment, the different surface structural features can at least partially divide functional regions in area, such that in some regions (i.e., for some viewpoints), one surface structural feature predominates or alone dominates or provides a functional effect for myopia control, while alternatively or additionally, in other regions, another surface structural feature predominates or alone dominates or provides a functional effect for myopia control. Alternatively or additionally, it is also possible that the first and second surface structural features jointly cause functional effects in at least several portions of the functional regions (i.e., for some viewpoints).

[0028] In a particularly preferred embodiment, a first surface structural feature is formed on the front surface of the spectacle lens, and a second surface structural feature is formed on the rear surface of the spectacle lens. Such spectacle lenses can be manufactured particularly simply, wherein the first and second surface structural features can interact effectively without adversely affecting each other. The “front surface” and “rear surface” of the spectacle lens are understood herein specifically as the front and rear surfaces of the spectacle lens substrate. It does not necessarily correspond to one of the surfaces of the finished spectacle lens. Instead, it is also possible that the spectacle lens substrate (e.g., after forming the front and / or rear surfaces) is further provided with one or more coatings. Such coatings may, for example, include protective coatings, overlays, hard coatings, colored coatings, anti-reflective coatings, anti-fog coatings, etc.

[0029] In a preferred embodiment, the functional region includes at least one combined action region, such that for each viewpoint of the spectacle lens within the combined action region, the functional effect is caused by the combination of the first and second surface structure features. Alternatively or additionally, in a preferred embodiment, the functional region includes at least one first dedicated action region and / or a second dedicated action region, such that for each viewpoint of the spectacle lens within the first or second dedicated action region, the functional effect is caused solely by the first or second surface structure feature. In other words, in the embodiment, it is preferred that, for example, the second surface structure feature is not active or absent in the first dedicated action region, and / or the first surface structure feature is not active or absent in the second dedicated action region.

[0030] Therefore, it is possible to very effectively and selectively suppress undesirable side effects that are particularly critical (i.e., intolerable) to a certain area of ​​use (i.e., visual field) of the spectacle lens without impairing its functional effectiveness for myopia control. Thus, particularly in the preferred embodiment, the central dominant visual area is completely surrounded by a first dedicated action area, which is connected to the combined action area. Particularly preferably, the first surface structural feature includes microlenses, while the second surface structural feature particularly includes a gradient surface refractive power.

[0031] For example, it may be particularly advantageous to first use only (or primarily) microstructures (e.g., microlenses / tints) directly adjacent to the dominant visual area to produce functional effects (especially in the form of positive refractive addition), and to supplement or (partially replace) their effect toward the periphery of the lens by increasing the gradually increasing surface refractive power (positive refractive addition). This has already enabled an effective and efficient functional effect for myopia management near the central dominant visual area, while keeping astigmatic side effects very small through the slow increase in surface refractive power. Especially in the peripheral region, the formation of secondary images is simultaneously kept small or suppressed.

[0032] In a preferred embodiment, the spectacle lens includes:

[0033] - A continuous channel area extending continuously from the upper edge to the lower edge of the spectacle lens, including the central dominant viewing area; and

[0034] - A combined action area that is horizontally adjacent to a continuous channel area on both sides and extends continuously from the upper edge to the lower edge of the spectacle lens.

[0035] The additional refractive effect of spectacle lenses caused by the second surface structure features increases on both sides of the channel region away from the channel region.

[0036] In this embodiment, it is particularly preferred that the channel region includes a first upper dedicated action region and a first lower dedicated action region, wherein the additional action is generated substantially by a first surface structure feature (which in particular includes microlenses), and a second surface structure feature includes a gradient surface refractive power (with positive refractive additional action).

[0037] Compared to spectacle lenses where the central area is completely surrounded by the positive effect due to the gradual surface refractive power, the variant with only a lateral gradient of surface refractive power improves compatibility due to the significant reduction in distortion in all directions, even though the functional effect of the first surface structural feature (e.g., in the form of microlenses) is very effectively achieved in all directions, and therefore myopia control is very effective. Thus, high compatibility is achieved while simultaneously and effectively suppressing myopia progression.

[0038] In this specification, the directions “down” and “up” (and derived names, such as “below” and “above”) and the names used for directions “nasal side,” “temporal side,” “horizontal,” and “vertical” are always observed relative to the wearing position of the spectacle lens, which is determined, in particular, by centering data for the spectacle lens. Preferably, the “lower edge” and “upper edge” of the spectacle lens are understood as the lower and upper halves, more preferably the lower third or upper third, and even more preferably the lower quarter or upper quarter edge segments of the spectacle lens surface (front and / or rear surface). Particularly preferably, the upper edge or lower edge refers in particular to a segment of the entire edge of the spectacle lens that defines the uppermost or lowermost 20%, preferably 15%, even more preferably 10%, and most preferably 5% of the vertical height of the spectacle lens. The spectacle lenses mentioned in this specification can be, in particular, cut or ground (finished) spectacle lenses, or they can be uncut spectacle lenses.

[0039] In another aspect, the present invention relates to a method for manufacturing spectacle lenses, particularly those described herein, wherein the method includes creating a first surface structural feature on the front surface of the spectacle lens and a second surface structural feature on the rear surface of the spectacle lens. Particularly preferred is that the first surface structural feature is created during the casting of a semi-finished spectacle lens, and particularly includes microlenses. Alternatively or additionally, particularly advantageous, is that the second surface structural feature is created by grinding the rear surface, and particularly includes a gradient surface refractive power.

[0040] Finally, the present invention relates to the use of an eyeglass lens, one of the eyeglass lenses described herein, for compensating for myopic vision defects and / or slowing the progression of myopia. Attached Figure Description

[0041] The invention will then be further described with reference to the accompanying drawings and preferred embodiments, wherein:

[0045] Figure 4A schematic diagram illustrating an exemplary distribution of microlenses as a first surface structural feature in an eyeglass lens according to a preferred embodiment is shown. Detailed Implementation

[0046] A preferred embodiment of a spectacle lens with dual progressive control for myopia control combines two schemes: a "microlens" scheme located on the front surface of the lens, and a "peripheral effect enhancement" scheme located on the rear surface of the lens. See then for further details. Figures 1 to 4 An exemplary implementation of the preferred embodiment is described below:

[0047] Figure 1 A schematic distribution of various regions on a spectacle lens 10 according to a preferred embodiment is shown. Here, the spectacle lens 10 particularly includes a central dominant viewing region 20 having substantially constant refractive power. In this embodiment, the central dominant viewing region 20 is surrounded by functional regions, which in this case include a dedicated function region 19 and a combined function region 18. Compared to the central dominant viewing region 20, functional regions 18 and 19 have additional functional effects, which, in the preferred embodiment shown here, include at least one additional refractive effect compared to the central dominant viewing region 20. Here, the additional functional effects in functional regions 18 and 19 are achieved through a combination of a first surface structural feature and a second surface structural feature of the spectacle lens 10.

[0048] In the embodiment shown here, the first surface structural feature is formed, in particular, by a microlens, which causes at least a portion of the additional refractive effect compared to the central dominant viewing region 20. The second surface structural feature is formed, in particular, by a gradient surface refractive power, which, in turn, also causes at least a portion of the additional refractive effect compared to the central dominant viewing region 20. In this embodiment, it is particularly preferred that the first surface structural feature is formed on the front surface of the spectacle lens 10, while the second surface structural feature is formed on the rear surface of the spectacle lens.

[0049] Specifically, in the dedicated action region 19, the functional effect is generated essentially solely by the first surface structure feature, while in the combined action region 18, the functional effect is generated by both surface structure features together (i.e., overall). In other words, within the dedicated action region 19, it is preferable that there is essentially no gradual change in surface refractive power contributing to the positive refractive effect. In the dedicated action region 19, the contribution of the gradual change in surface refractive power to the positive refractive effect is particularly no more than about 20%, preferably no more than about 10%, and most preferably no more than about 5%. Preferably, in the combined action region 18, each of the two surface structure features contributes at least about 10% to the positive refractive effect, more preferably at least about 20%, and most preferably at least about 25%.

[0050] In a preferred embodiment, the dedicated functional area 19 completely surrounds the central main viewing area 20, while the combined functional areas 18 are laterally adjacent to the dedicated functional area 19 on both sides. In this way, in the exemplary embodiment shown, the dedicated functional area 19 and the central main viewing area 20 together form a continuous channel region. Therefore, this channel region is the area in this embodiment that is substantially devoid of second surface structural features. This will be described later... Figure 2 In the figure, this channel area is indicated by reference numeral 12.

[0051] Here, the channel region 12 extends continuously from the upper edge 14 of the spectacle lens 10 to the lower edge 16 of the spectacle lens 10. This channel region 12 is surrounded on the nasal and temporal sides by corresponding nasal-side action segments 18n and temporal-side action segments 18t of the combined action region 18, which directly adjoin the channel region 12, particularly along the corresponding nasal-side channel boundary line 26n and temporal-side channel boundary line 26t. Figure 2 ).

[0052] Figure 2 A schematic diagram illustrates an exemplary change in the distribution of refractive power caused by a second surface structural feature (in the form of a gradient surface refractive power) particularly implemented on the rear surface of the spectacle lens 10 according to a preferred embodiment. This schematic diagram can, in particular, substantially correspond to... Figure 1 The spectacle lens 10. Therefore, the channel region 12 extends from the upper edge 14 of the spectacle lens 10 to the lower edge 16 of the spectacle lens. The nasal action segment 18n and the temporal action segment 18t are adjacent to the channel region 12 laterally.

[0053] Apart from the entire edge contour of the eyeglass lens Figure 2 The lines shown represent lines (isolines) of the same surface refractive power on the rear surface of the spectacle lens 10. For example, the refractive power distance between adjacent lines can be... Figure 2 The difference is indicated by 0.5 dpt. As can be seen from this, the entire channel region 12 is located in a region with substantially constant surface refractive power. For the entire spectacle lens 10, this means that the total refractive power of the spectacle lens is substantially constant here (especially in the central dominant vision region 20), or the functional effect is determined by the first surface structure features (especially in the dedicated effect region 19).

[0054] Regardless of the absolute value of refractive power, in Figure 2In the illustration, the spectacle lens 10 preferably has the minimum refractive power in the channel region 12. Due to the characteristics of the second surface structure, the surface refractive power increases continuously toward the lateral action segments 18n and 18t in any case, and in the schematic diagram, it reaches its corresponding maximum value at approximately the middle height in the region of the side edge of the spectacle lens 10.

[0055] The rear surface is designed here, particularly using freeform technology. Here, the spectacle lens 10 achieves the effect required for correcting hyperopia in the channel region 12 (especially in the central dominant visual region 20). An increased effect is introduced in the peripheral lateral regions (especially in the combined effect region 18), such that the spectacle lens, due to the second surface structural features, receives an additional effect of 2.5 dpt (second positive refractive additional effect) on the temporal side within approximately 25 mm of the center point of the central dominant visual region 20, and an additional effect of 2.0 dpt (second positive refractive additional effect) on the nasal side within approximately 25 mm of the center point of the central dominant visual region 20. In the vertical direction, due to the second surface structural features, the channel region extends essentially without additional effect, while a moderate increase in effect is observed above and below.

[0056] Particularly preferably, the maximum surface refractive power of the posterior surface of the spectacle lens in the nasal and temporal action zones differs from each other by no more than about 3 dpt, preferably no more than about 2 dpt, more preferably no more than about 1 dpt, and most preferably no more than about 0.5 dpt. Alternatively or simultaneously, depending on the embodiment and field of application, the maximum surface refractive power of the posterior surface of the spectacle lens in the nasal and temporal action zones is at least about 1 dpt greater than the minimum surface refractive power of the posterior surface of the spectacle lens in the channel region 12, preferably at least about 1.5 dpt, more preferably at least about 2 dpt, more preferably at least about 2.5 dpt, and most preferably at least about 3 dpt.

[0057] In a preferred embodiment, the first surface structural feature is achieved, in particular, through microstructures on the front surface of the spectacle lens. For example, in Figure 3 As exemplarily illustrated, the microstructure is specifically designed as microlenses 30 (particularly protrusions on the lens body) to image a portion of the light passing through these microlenses (tints) in front of the retina to counteract eye growth. For this purpose, the tints 30 preferably have a positive refractive addition effect (first positive refractive addition effect). Here, for example, an addition effect of about 3.5 dpt has proven effective. However, other effects (e.g., 2 to 5 dpt) are also feasible and should demonstrate similar effects. The optical effect of the protrusions is produced by refraction at the interface between the lens body and the environment (e.g., air or a protective layer in the area of ​​the protrusion).

[0058] The "microlens" designation is specifically understood as a small, particularly circular, region on the anterior surface 32 of the spectacle lens that differs in function from the region surrounding these elements (i.e., the so-called primary function). This function is achieved by altering the curvature of the anterior surface in this region. Microlenses, for example, have a diameter of approximately 1 mm and an function differing from the primary function by approximately 3.5 dpt (first positive refractive additional function), and are particularly preferably based on a Fibonacci spherical distribution (see...). Figure 4 Arranged around the central primary viewing area 20, wherein the central primary viewing area 20 preferably has a diameter ranging from about 5 mm to about 20 mm, and more preferably from about 10 mm to about 15 mm, preferably without microlenses to obtain good central vision. The microlenses are preferably already included in the mold of the semi-finished spectacle lens.

[0059] In summary, the concept of this invention is to combine two solutions for myopia management eyeglass lenses. Therefore, an eyeglass lens for myopia management with such dual progressive control incorporates two designs for myopia control, and for example, has multiple additional acting elements (microlenses or small lenses) on the front surface and a rear surface that introduces additional effects (e.g., as progressive surface refractive power) in the periphery.

[0060] Different concepts of spectacle lenses used for myopia control have different optical defects. By combining these designs, different optical defects can be combined, thereby preventing major errors that excessively impair compatibility. Consequently, a greater effect acting in front of the retina can be introduced. Therefore, the present invention achieves better myopia control effectiveness by providing a greater effect in front of the retina, while simultaneously improving compatibility through an adaptive distribution of optical defects.
