Description
Technical Field
The present application relates to the technical field of ophthalmic lenses, and in particular, to an ophthalmic lens having a plurality of micro defocus regions, and frame glasses having the same.
Background
Ametropia of the human eye includes myopia, hyperopia, astigmatism, and the like, with myopia being the most common ametropia, especially in adolescents. When the eye is in a static state, external parallel light rays are focused on the front of retina instead of the central fovea of macula retinas after passing through the diopter system of the eye, so that a patient cannot see distant objects clearly, namely myopia occurs; that is, myopia occurs when the axial length of the eye is greater than the focal length of the eye's optical system.
Ophthalmic devices such as frame lenses or contact lenses are commonly used to correct or enhance a patient's vision, such as correcting myopia with a negative lens and correcting hyperopia with a positive lens. The ophthalmic lenses conventionally used for myopia correction are single-shot (monofocal) ball lenses, i.e. the refractive power of the lenses is the same from center to edge. The best focus plane Petzval plane produced by a single sphere lens is spherical, whereas the eyeball is generally ellipsoidal, thus resulting in a peripheral Petzval plane behind the retina, creating hyperopic defocus. Hyperopia and defocus promote ocular axis growth and thus progression of myopia.
There are a variety of ophthalmic lenses for myopia prevention and control, one of which involves arranging a plurality of microlenses on a single-ball lens, and inhibiting myopia progression by using these microlenses to form an image of an object in front of the retina, see CN 104678572A.
However, there is still a need for myopia prevention and control lenses that can effectively inhibit the increase in axial length of the eye without significantly affecting visual quality, while improving patient wear compliance and reducing inter-individual variability.

Detailed Description
In the following description, numerous details are provided to provide a thorough understanding of the present application. However, it will be understood by those skilled in the art that the following description illustrates preferred embodiments of the present application by way of example only and that the present application may be practiced without one or more of these details. In addition, some technical features that are known in the art have not been described in detail in order to avoid obscuring the present application.
In order to provide a thorough understanding of the embodiments of the present application, a detailed structure will be presented in the following description. It will be apparent that embodiments of the present application may be practiced without limitation to the specific details that are set forth by those skilled in the art. Preferred embodiments of the present application are described in detail below, however, the present application may have other embodiments in addition to these detailed descriptions.
In order to prevent myopia as much as possible and also to satisfy clear vision after wear, one aspect of the present application provides an ophthalmic lens.
The ophthalmic lenses of the present application will be described in detail below in conjunction with fig. 1.
As shown in fig. 1, the ophthalmic lens 1 comprises a central zone 5, and a plurality of first refractive zones 2 and a plurality of second refractive zones 3, the central zone 5 being the zone enclosed by the plurality of first refractive zones 2 having a prescribed refractive power based on the prescription of the human eye, the plurality of first refractive zones 2 being closer to the center of the ophthalmic lens than the plurality of second refractive zones 3, the spacing between the plurality of second refractive zones 3 being greater than the spacing between the plurality of first refractive zones 2. In the embodiment shown in fig. 1, a plurality of first refractive regions 2 may be arranged on one or more first patterns, for example 2, 3, 4, or 5 first patterns.
The one or more first patterns may be arranged concentrically with the center of the ophthalmic lens 1. The first pattern may be annular, ring-like, or any shape rotationally symmetric along the center of the lens. For simplicity, each first pattern includes only a minimum number of first refractive regions that can substantially arrange the pattern, e.g., fig. 1 shows a total of 6 annular patterns, including one or more first patterns. The plurality of first patterns may be the same as or different from each other. By ring-like is meant that a majority of the first refractive regions 2 are arranged on one or more circumferences, while the remaining first refractive regions 2 are outside the circumference, illustratively arranged on the inner side of the circumference and immediately adjacent to the circumference, and/or on the outer side of the circumference and immediately adjacent to the circumference, illustratively, on a regular basis (e.g. equally spaced), e.g. the plurality of first refractive regions 2 may be arranged in a shape resembling the outer contour of a sun flower.
The ophthalmic lens 1 is further provided with a plurality of second refractive areas 3 relatively distant from the centre of the ophthalmic lens 1, formed as a plurality of mutually spaced island-shaped areas arranged on one or more second patterns. The one or more second patterns may be arranged concentrically with the center of the ophthalmic lens 1, there is no explicit limitation as to the maximum size of the second pattern, and a person skilled in the art may choose an appropriate range as desired. Similar to the first pattern, for simplicity, each second pattern includes only a minimum number of second refractive regions that are capable of substantially arranging the pattern. The second pattern may be annular, ring-like, or any shape rotationally symmetric along the center of the lens. The plurality of second patterns may be the same as or different from each other. The first refractive region 2 and the second refractive region 3 each have a refractive power different from the prescribed refractive power. Both the first refractive zone 2 and the second refractive zone 3 are capable of focusing light at a location outside the retina of the eye, thereby inhibiting the development of refractive errors of the eye. The central zone 5 on the ophthalmic lens 1, the peripheral zone 6 outside the first refractive zone 2 and the second refractive zone 3, and the intermediate zone 7 between the first refractive zone 2 and the second refractive zone 3 can all have a prescribed refractive power. The central region 5 of the ophthalmic lens 1 is designed to be the position where the pupil is directly facing when the user is looking straight ahead behind the glasses. Thus, after correction in the central region 5, the image is just on the fovea of the macula to ensure clear vision. The prescribed optical power is the optical power prescribed by the vision prescription and can be understood as the conventional power. The first refractive region 2 is a region having a refractive power different from the prescribed refractive power. Illustratively, the plurality of first refractive regions 2 may meet each other on the ophthalmic lens 1 along a first pattern. The projection of each first refractive zone 2 onto the lens may be circular, oblate, polygonal, etc. For polygons, the number of edges may be greater than or equal to 6. When the first refractive region 2 is circular, any adjacent two of the plurality of first refractive regions 2 may be tangential to each other along the first pattern.
The plurality of first refractive regions 2 are used to form a dense addition (i.e., adding positive power to the prescribed power) at the periphery of the central region 5. The present application achieves better myopia control by providing a high density near-focus zone near the central optical zone, and the inventors have found that near-focus formed by densely boosting (e.g., at least in an annular zone formed by centering the ophthalmic lens center at an inner annular diameter of 3.0mm (e.g., 4.0mm, 5.0mm, 6.0mm, 7.0mm, 8.0mm, 9.0mm, 10.0mm, 11.0mm, or any value therebetween) to an annular zone formed by outer annular diameter of 28.6mm (e.g., 15.0mm, 19.8mm, 24.2mm, or any value therebetween) can impart more stimulus to the retina, thereby inhibiting elongation of the eye axis, and incident light beams passing through the annular zone are projected generally between 10 and 20 degrees adjacent to the macular fovea. In agreement with this, studies have shown that competitive myopic defocus signals applied near the fovea of the macula have a stronger and more consistent effect on slowing axial growth of the eye axis (E.L.Smith III et al, ecceticity-dependent effects of simultaneous competing defocus on emmetropization in infant rhesus monkeys, vision Research,17 (3): 32-40,2020).
Preferably, the intensive addition may be performed in an annular region formed with the ophthalmic lens center as the center inner ring diameter of 3.0mm to the outer ring diameter of 28.6mm, for example, at least in an annular region formed with the ophthalmic lens center as the center inner ring diameter of 9.0mm to the outer ring diameter of 15.0mm, for example, the plurality of first refractive regions 2 may be provided at least in an annular region with the ophthalmic lens center as the center inner ring diameter of 9.0mm to the outer ring diameter of 15.0mm, or at least a part of the first refractive regions 2 may be included in an annular region with the ophthalmic lens center as the center inner ring diameter of 9.0mm to the outer ring diameter of 15.0 mm. That is to say that at least part of the plurality of first refractive regions 2 needs to be arranged in the annular region, while other parts may be arranged outside the annular region, and in order to achieve a dense addition in this region, it is preferable that part or all of the plurality of first refractive regions 2 can be distributed over the annular region. In general, the plurality of first refractive regions 2 may be disposed within an annular region having an inner annular diameter of 3.0mm to an outer annular diameter of 28.6mm, for example, disposed entirely within the annular region. Illustratively, the plurality of first refractive regions 2 may be disposed within an annular region of inner annular diameter 3.0mm to outer annular diameter 24.2mm, for example disposed entirely within the annular region. Illustratively, the plurality of first refractive regions 2 may be disposed within an annular region of inner annular diameter 3.0mm to outer annular diameter 19.8mm, for example disposed entirely within the annular region. Because it is considered that the lens moves up and down during wear, intensive addition of light in an annular region having an extra width is required in order to ensure coverage of the retinal defocus-sensitive region. Fig. 7 is the calculated field curvature integral (negative field curvature absolute value) for lenses with different microlens arrangements placed on the surface of model eyes Liou & Brenna by optical simulation software Optic Studio Zemax. As shown in fig. 7, the lens of the present invention can provide more defocus stimulus to the retina by providing densely packed microlenses at portions corresponding to the defocus-sensitive region of the retina, see a preferred example (densely packed microlenses thereof are located substantially in an annular region having an inner diameter of 9.5mm and an outer diameter of 14 mm). In a small scale experiment, the ophthalmic lenses of the present application were found to be effective in promoting choroidal thickening (average choroidal thickening at 2 weeks (6.+ -.6)%) and short term choroidal thickening is currently believed to be associated with long term ocular axis growth control effects.
Of course, within each first pattern, there may also be a smaller spacing between the first refractive regions 2, that is to say between adjacent first refractive regions 2 in the direction along which the first pattern extends (e.g. a spacing of less than 0.5mm, such as 0.4mm, 0.3mm, 0.2mm, 0.1 mm). However, in any case, the spacing between the first refractive regions 2 may be smaller than the spacing between the second refractive regions 3, e.g. the spacing between the first refractive regions 2 in the direction along which the first pattern extends is smaller than the spacing between the second refractive regions 3 in the direction along which the second pattern extends, but in some directions (e.g. radially) the spacing between the first refractive regions 2 may also be smaller, equal or even larger than the spacing between the second refractive regions 3 in the same direction. It is also contemplated that the density of the first refractive regions 2 may be greater than the density of the second refractive regions 3, i.e. the first refractive regions 2 may be more closely spaced overall, e.g. the average of the spacing between the first refractive regions 2 and their surrounding first or second refractive regions is less than the average of the spacing between the second refractive regions 3 and their surrounding first or second refractive regions. The density of refractive regions refers to the number of refractive regions per unit area. Typically, the dimensions of each refractive zone are small and the dimensions of the different refractive zones do not differ much, so the density can be used to describe the density of the first refractive zone 2 and the second refractive zone 3. Of course, the distance may also be used to measure the concentration of the first refractive region 2 and the second refractive region 3.
The second refractive zone 3 also has a refractive power different from the prescribed refractive power. The plurality of second refractive regions 3 may be spaced apart from each other, forming island-shaped regions. The inventors have found that maintaining a suitable spacing between the second refractive regions 3 not only improves compliance and visual comfort for the wearer, but also minimizes the differences between the myopia prevention and control effects of different patients. Without wishing to be bound by any theory, the inventors believe that if the near vision defocus range is too large, insufficient light is focused on the retina, which may make it difficult for the eye to determine whether the accommodative retina is looking for a focus point anteriorly or posteriorly, resulting in a large difference in effect between different patients, so it is important to maintain sufficient spacing between the plurality of second refractive regions 3.
In the present application, by adding light in the first refractive region and the second refractive region, the refractive power (e.g., -0.75D) in a specific micro-region at the periphery of the central region 5 is corrected as compared to the refractive power (e.g., -3.5D) of the central region 5, thereby forming myopia defocus on the peripheral retina that is perceivable by the retina and is imperceptible by the brain, thereby controlling the eye axis growth without affecting or significantly affecting the visual quality, thereby acting to prevent or retard myopia progression.
The first refractive regions 2 may be arranged on one or more first patterns, wherein fig. 1 shows the case where the first refractive regions 2 are arranged on one first pattern; fig. 2 shows a case where the first refractive regions 2 are arranged on a plurality of first patterns. Referring to a part in fig. 2 shown in fig. 3, the first refractive region 2 may be arranged on a first pattern 2a (hereinafter referred to as an inner first pattern 2a for convenience of description) near the central region 5 and a first pattern 2b (hereinafter referred to as an outer first pattern 2a for convenience of description) distant from the central region 5 and adjacent to the first pattern 2 a. The first refractive regions in the inner first pattern 2a may meet or be immediately adjacent to each other. By immediately adjacent is meant that there is a smaller spacing between the first refractive regions, for example, smaller than the spacing of the second refractive regions 3. The first refractive regions in the outer first pattern 2b may meet or be immediately adjacent to each other. The inner first pattern 2a and the outer first pattern 2b may be contiguous or in close proximity to each other. In order to increase the dense addition of the first refractive regions 2, the first refractive regions in the inner first pattern 2a and the first refractive regions in the outer first pattern 2b may meet both within the pattern and between the patterns. In this case, the diameter of the first refractive region in the inner first pattern 2a may be set slightly smaller than the diameter of the first refractive region in the outer first pattern 2b, so that the number of the first refractive regions in the inner first pattern 2a and the number of the first refractive regions in the outer first pattern 2b may be equivalent. Of course, the first refractive regions in the inner first pattern 2a and the first refractive regions in the outer first pattern 2b may also be provided with the same diameter, so that the number of first refractive regions in the inner first pattern 2a may be smaller than the number of first refractive regions in the outer first pattern 2 b. Although fig. 2-3 describe an embodiment in which the first refractive regions 2 are arranged in 2 first patterns, it will be appreciated that the first refractive regions 2 may be arranged in more first patterns.
Although the first refractive regions 2 are illustrated as being uniformly disposed along the extending direction of the first pattern in the illustrated embodiment, the first refractive regions 2 may be non-uniformly disposed along the extending direction of the first pattern in an embodiment not shown. The extending direction of the first pattern refers to the extending direction of the lines formed substantially by the first pattern. In fig. 1 to 2, the first patterns are each formed as a circular ring (21), and then the extending direction of the first patterns can be understood as the extending direction of the lines forming the circular ring, that is, the circumferential direction. In other embodiments, for a first pattern, it may include non-uniformly arranged first refractive regions in addition to uniformly arranged first refractive regions. The unevenly arranged first refractive regions are discretely distributed along the extending direction of the first pattern, which may have a larger spacing therebetween, but they are contiguous or closely adjacent to those first refractive regions 2 which are contiguous or closely arranged along the extending direction of the first pattern. Alternatively, adjacent first patterns may not meet (i.e., not as in fig. 2) or be immediately adjacent to each other, but have a slightly larger pitch. The spacing between adjacent patterns (pattern spacing for short) refers to the distance between the refractive region in one pattern and the refractive region in the adjacent other pattern along the radial direction of the lens. When the refractive regions on different patterns are each radially distributed along the radial direction, the pattern pitch may be determined by two refractive regions adjacent in the radial direction. When the refractive regions on the different patterns are not radially distributed along the radial direction, the pattern pitch may be half of the difference between the dimension of the innermost profile of the outer pattern in the predetermined radial direction and the dimension of the outermost profile of the inner pattern in the predetermined radial direction.
The second refractive regions 3 may be arranged on one or more second patterns, as in the embodiments shown in fig. 1-3, each of which shows the second refractive regions 3 arranged in a plurality of second patterns. In this case, the spacing between the second refractive regions 3 on the second pattern further outward may be greater. Of course, the second refractive regions 3 on each second pattern may also be arranged with a pitch that is the same, e.g. the pitch between the second refractive regions 3 in different second patterns may be equal, which may appear as a larger number or size of second refractive regions 3 on the second pattern closer to the outer side. Further, the pitches between the adjacent second patterns may be equal. Of course, the pattern pitch of the second pattern may be set to be larger as the second pattern is located closer to the outer side.
Illustratively, as a whole, all patterns, including the first pattern and the second pattern, for patterns further from the center of the ophthalmic lens, the larger the spacing between adjacent two refractive regions within the pattern, see fig. 1, 4 and 5. That is, in any two adjacent patterns, the spacing between refractive regions in the pattern relatively closer to the center of the ophthalmic lens is less than the spacing between refractive regions in the pattern farther from the center of the ophthalmic lens. Of course, the above-described rule may exist only for the second pattern. In particular, when there are multiple first patterns, the first refractive regions within each first pattern may be contiguous or in close proximity to each other, see fig. 2, in order to ensure dense addition of light at the portion corresponding to the retinal defocus-sensitive region. In this case, the spacing between the second refractive regions within the second pattern further from the center of the ophthalmic lens may be greater. In an exemplary embodiment, the spacing between adjacent two refractive regions within a single pattern increases gradually from zero, but not more than 2.00mm, preferably not more than 1.90mm, more preferably not more than 1.80mm, for example to 1.20mm, from the innermost pattern to the outermost pattern.
Although in the illustrated embodiment the second refractive regions 3 are illustrated as being uniformly arranged along the extending direction of the second pattern, in an embodiment not shown, the second refractive regions 3 may also be non-uniformly arranged along the extending direction of the second pattern. The extending direction of the second pattern refers to the extending direction of the lines substantially formed by the second pattern. In fig. 1 to 6, the second pattern is formed as a circular ring (31), and then the extending direction of the second pattern can be understood as the extending direction of the lines forming the circular ring, that is, the circumferential direction. In other embodiments, for a second pattern, it may include non-uniformly arranged second refractive regions in addition to uniformly arranged second refractive regions. The unevenly arranged second refractive areas are discretely distributed along the extension direction of the second pattern, which may have a larger spacing therebetween, but which are in abutment or close proximity to those second refractive areas 3 arranged along the extension direction of the second pattern. Alternatively, adjacent second patterns may not meet (i.e., not as in fig. 5) or be immediately adjacent to each other, but have a slightly larger pitch (e.g., as shown in fig. 1 and 2).
In one embodiment, each of the first patterns may have a ring shape. Referring back to fig. 1, the first refractive region 2 may be arranged on a first ring 21. Of course, in other embodiments not shown, each first pattern may also be polygonal or other rotationally symmetrical patterns, etc. The number of first rings 21 may be one or more. When the number of first rings 21 is plural, adjacent two first rings 21 may be in contact with each other or in close proximity or with a slightly larger pitch. The plurality of second refractive regions 3 may be arranged on one or more second rings 31. The second ring 31 is arranged concentrically with the first ring 21. Intervals may be provided between the plurality of second rings 31. In the case where the first ring 21 and the second ring 31 are collectively referred to as rings, the intervals between adjacent rings may be equal. Of course, the spacing between adjacent rings may also be increased gradually in a direction away from the central region 5, that is, the pattern spacing may be increased gradually. Or the first rings 21 have equal first spacing therebetween and the second rings 31 have equal or unequal second spacing therebetween. The first pitch is smaller than the second pitch.
In another embodiment, the first patterns (if any), the second patterns, and the first and second patterns may all be contiguous or immediately adjacent. As shown in fig. 5 to 6, the first ring 21 and the second ring 31 may be connected or closely adjacent to each other, and the adjacent second rings 31 may be connected or closely adjacent to each other. In fact, in this case it is not so clear which are the first loops and which are the second loops. But as a whole it can still be clearly seen that the spacing between the refractive areas on the outside is significantly larger than the spacing between the refractive areas on the inside. Within the scope of the present application, a pattern having a spacing between at least two adjacent refractive regions within the same pattern of less than 0.5mm is referred to as a "first pattern" for clarity. In one embodiment, since there is little or no space (less than 0.5 mm) between the refractive regions on the innermost one of the patterns and on the one adjacent thereto, the number of first rings 21 can be considered to be 2 and the number of second rings 31 to be 6. The spacing between the second rings 31 is zero and the spacing between the first rings 21 and the second rings 31 is also zero. The closer to the outside, the larger the spacing of the second refractive regions 3 within each second ring 31.
Of course, the first refractive zone 2 and the second refractive zone 3 may not be distributed on the ring, but may be distributed on only one side of the central zone 5, such as the upper side, lower side, left side or right side in the figure, or may be a partial zone surrounding the periphery of the central zone 5. They may be arranged symmetrically with respect to the central region 5 or asymmetrically. The distribution can be adjusted according to the vision condition of the wearer. As shown in fig. 4, the first or second refractive region may not be provided in region B of the drawing. This region B is used for the wearer to switch between distance vision (e.g., looking at a blackboard) and near vision (e.g., looking at a desktop book) without having to move the head substantially, so this region may optionally have a different power than the prescribed power for near vision tasks.
According to some exemplary embodiments of the present application, the first refractive region 2 has a refractive power obtained by adding a positive refractive power to the prescribed refractive power, that is, the overall refractive power of the lens to which the first refractive region 2 corresponds is corrected as compared to the prescribed refractive power. In some exemplary embodiments, the first refractive zone 2 corresponds to a lens having an overall refractive power that is less than the refractive power of the other zones (i.e., the prescription refractive power) other than the first refractive zone 2 and the second refractive zone 3. In this case, the first refractive region 2 corresponds to a convex lens added to the original lens.
Here, each of the first refractive regions 2 may have a uniform refractive power or may have a different refractive power. In a preferred embodiment, each first refractive zone 2 has a uniform refractive power. In this application, the positive refractive power of the first or second refractive region as increased relative to the central region 5 is simply referred to as addition. Within the scope of the present application, the addition level of the first refractive zone 2 relative to the central zone 5 is in the range +1.0d to +10.0d, for example +1.0d, +1.5d, +2.5d, +3.0d, +3.5d, +4.0d, +4.5d, +5.0d, +5.5d, +6.0d, +6.5d, +7.0d, +7.5d, +8.0d, +8.5d, +9.0d, +9.5d, or +10.0d. Illustratively, the addition level of the first refractive zone 2 may be constant or gradually increasing or decreasing, or stepwise increasing or decreasing, in a direction away from the central zone 5. By stepwise increase or decrease is meant that adjacent ones of the patterns of the first refractive zone 2 have a first power, while the patterns of the first refractive zone 2 outside the patterns may have a second power. The second addition degree may be greater or less than the first addition degree.
According to some exemplary embodiments of the present application, for each first refractive zone 2, it may be a microlens attached to the original lens. For example, it may be a convex lens. Alternatively, the first refractive zone 2 may have a contour that is consistent with the original lens, i.e. does not protrude from the original lens. In this case, the first refractive region 2 may have a refractive index different from that of the original lens. For example, the first refractive zone 2 and the original lens may be made of different materials, or the refractive index of different zones when the lens materials are polymerized may be adjusted by adjusting the ion concentration therein, or a specific zone may be irradiated with ultraviolet rays to be re-polymerized to change the refractive index.
The maximum size of the projection of each first refractive zone 2 onto the lens may be between 0.5-2.2mm, for example 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, or 2.1mm, or any value therebetween. When the projection of the first refractive zone 2 on the lens is circular, the diameter of the circular shape may be between 0.5-2.2 mm.
The central region 5 may be, for example, circular, polygonal, or other rotationally symmetrical pattern. The maximum dimension of the central zone 5 may be 3.0-11.0mm, for example 3.0mm, 4.0mm, 5.0mm, 6.0mm, 7.0mm, 8.0mm, 9.0mm, 10.0mm, or 11.0mm, or any value in between. When the central region 5 is circular, the diameter of the central region 5 may be between 3.0 and 11.0 mm.
Briefly described, in one embodiment: it can be assumed that the prescribed refractive power is-3.5D, the diameter of the central zone 5 of the lens is 10mm, and the first refractive zone 2 is located at a distance of around 5mm from the center. Illustratively, the first refractive zone 2 may be located at a boundary immediately adjacent to the central zone 5 of diameter 10mm, and the number of first refractive zones 2 may be pi x d1/d2, where d1 is the diameter of the central zone 5 and d2 is the largest dimension of the first refractive zone 2. When d2 is 1.2mm, the number of first refractive regions 2 can be calculated as 26. Of course, the number of first refractive regions 2 may be 26-35, and correspondingly, the maximum size of the first refractive regions 2 and the diameter of the central region 5 may be matched. By densely arranging the first refractive regions 2 around the central region 5, the eye axis lengthening can be effectively retarded, and the myopia suppressing effect is better.
According to some exemplary embodiments of the present application, the second refractive zone 3 has a refractive power obtained by adding a positive refractive power to the prescribed refractive power, that is, the overall refractive power of the lens corresponding to the second refractive zone 3 is corrected compared to the prescribed refractive power. In some exemplary embodiments, the second refractive region 3 corresponds to a lens having an overall refractive power less than the prescribed refractive power. The second refractive zone 3 may correspond to a convex lens added to the original lens.
Here, each of the second refractive regions 3 may have a uniform refractive power or may have a different refractive power. In a preferred embodiment, each second refractive zone 3 has a uniform refractive power. Within the scope of the present application, the addition level of the second refractive zone 3 relative to the central zone 5 is in the range +1.0d to +10.0d, for example +1.0d, +1.5d, +2.5d, +3.0d, +3.5d, +4.0d, +4.5d, +5.0d, +5.5d, +6.0d, +6.5d, +7.0d, +7.5d, +8.0d, +8.5d, +9.0d, +9.5d or +10.0d. Illustratively, the addition level of the second refractive zone 3 may be constant or gradually increasing or decreasing, or stepwise increasing or decreasing, in a direction away from the central zone 5. Illustratively, the second refractive region 3 and the first refractive region 2 may have equal add power. Illustratively, the first refractive zone 2 and the second refractive zone 3 may have a gradual or stepwise increasing or gradual or stepwise decreasing power as a whole, in a direction away from the central zone 5.
According to some exemplary embodiments of the present application, for each second refractive zone 3, it may be a microlens attached to the original lens. For example, it may be a convex lens. Alternatively, the second refractive zone 3 may have a contour that is consistent with the original lens, i.e. does not protrude from the original lens. In this case, the second refractive zone 3 may have a refractive index different from that of the original lens. For example, the second refractive zone 3 and the original lens may be made of different materials, or the refractive index of different zones when the lens materials are polymerized may be adjusted by adjusting the ion concentration therein, or a specific zone may be irradiated with ultraviolet rays to be re-polymerized to change the refractive index.
The maximum size of the projection of each second refractive zone 3 onto the lens may be between 0.5-2.2mm, for example 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, or 2.1mm, or any value therebetween. When the projection of the second refractive zone 3 on the lens is circular, the diameter of the circular shape may be between 0.5-2.2 mm.
As previously described, the first refractive regions 2 may be arranged on one or more first rings 21 and the second refractive regions 3 may be arranged on one or more second rings 31. The second ring 31 is arranged concentrically with the first ring 21. The spacing between them may be equal. By way of illustration of one embodiment, assuming that there are one first ring 21 and five second rings 31, the largest second ring 31 may have a diameter of 30mm (radius of 15 mm), the central zone 5 has a diameter of 10mm (radius of 5 mm), and the first refractive zone 2 and the second refractive zone 3 each have a diameter of 1.2mm, the spacing between adjacent rings may be (15-5-0.6)/5-1.2 ≡0.7mm, i.e. the spacing between adjacent rings (i.e. the spacing between two refractive zones on adjacent rings in the radial direction) is approximately 0.7mm. In some embodiments, the spacing between adjacent rings or adjacent patterns may also be unequal, for example, the spacing between adjacent patterns may be equal to 0.2 to 1.5 times, such as 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, or 1.5 times the diameter of the first refractive region 2 or the second refractive region 3. In still other embodiments, the spacing between at least two adjacent rings or adjacent patterns is equal to 0.
In the case where the plurality of first refractive regions and the plurality of second refractive regions are each microlenses, the plurality of first refractive regions may be considered microlenses near the center of the ophthalmic lens, while the plurality of second refractive regions are considered microlenses far from the center of the ophthalmic lens. The approaching and separating as referred to herein are not absolute, but relative. The microlenses near the center of the ophthalmic lens are part of all microlenses, while the microlenses far from the center of the ophthalmic lens are another part of all microlenses, the former part being closer to the center of the ophthalmic lens than the latter part, and the latter part being farther from the center of the ophthalmic lens than the former part.
According to some exemplary embodiments of the present application, the number of first refractive regions 2 on each first ring 21 and the number of second refractive regions 3 on each second ring 3 may be the same. Preferably, the first refractive zone 2 and the second refractive zone 3 total 170-400; preferably 190-300.
Illustratively, the plurality of first refractive regions 2 and the plurality of second refractive regions 3 are distributed over a plurality of rays 4 starting from the center of the ophthalmic lens. The arrangement of the ray distribution is that after the user wears the spectacle lens, the user has ray-shaped clear areas for viewing objects in the upper and lower nasal-temporal directions, and the requirements of the user on viewing objects in all directions of the upper and lower nasal-temporal directions are considered, especially under the condition of smaller pattern spacing. Each ray 4 has a first refractive zone 2 and a second refractive zone 3 distributed thereon. The number of first refractive regions is less than, equal to, or greater than the number of second refractive regions on each ray 4. Illustratively, when the number of rays 4 is 2n, these rays 4 form n straight lines. Of course, in other embodiments not shown, portions of the plurality of first refractive regions 2 and the plurality of second refractive regions 3 may not be distributed over the rays, e.g. the refractive regions on some rings may be staggered with respect to the refractive regions on adjacent rings. When both the plurality of first refractive areas 2 and the plurality of second refractive areas 3 are distributed over the rays 4, the number of refractive areas on each ring is equal, in which case radially continuous blank areas, i.e. radially continuous distance refractive correction areas, will be formed outside the central optical zone, which helps to provide good visual quality. Alternatively, the number of refractive regions on the ring closer to the central region 5 may be smaller, and correspondingly, the number of refractive regions on the ring further from the central region 5 may be larger. Alternatively, the first refractive zone 2 and the second refractive zone 3 may have a gradually or stepwise increasing size on each ray as a whole and a gradually or stepwise decreasing addition power in a direction away from the central zone 5. By means of optical optimization, the arrangement mode can maintain basically constant low-intensity 'image jump' in the whole lens range under the condition that other parameters are unchanged, and by combining a linear and continuous far-distance diopter correction area, a good visual effect can be provided for a subject, the subject is easy to adapt, and wearing compliance is high. The image jump may be represented simply by the product of the addition of the first or second refractive region and its corresponding radius, in which case the term "substantially constant" means that the discrete coefficient of this product of the first refractive region and the second refractive region is less than 30%, preferably less than 25%, more preferably less than 20% over the entire lens range.
For example, additional second refractive regions may also be distributed between two adjacent rays 4, which may also be arranged in a regular pattern. For clarity of description, the pattern in which the additional second refractive regions are arranged is referred to herein as an add pattern 41, as shown in fig. 8A. Optionally, an additional pattern 41 may be provided between each adjacent two rays 4. Alternatively, the additional pattern 41 may be provided between a part of the two adjacent rays 4, while no pattern is provided between another part of the two adjacent rays 4 (i.e. white space is formed). In this case, the additional patterns 41 and the margin may be alternately arranged as shown in fig. 8B. As a whole, all the additional patterns 41 may be distributed divergently with respect to the central region 5. Each additional pattern 41 may be linear as shown in the figure or curved in any way.
Illustratively, instead of the plurality of rays 4, the plurality of first refractive regions and the plurality of second refractive regions may be distributed over a plurality of curves 42, as shown in fig. 8C-8D. These curves 42 may be divergently distributed with respect to the central region 5. That is, two points of intersection m on adjacent curves 42 with an intersecting circle (see dashed lines in the figure) centered on the center of the ophthalmic lens 1 And m 2 The distance between the two gradually increases with the diameter of the intersecting circle. Illustratively, for the same intersection circle, it may intersect all of the curves 42, and the distance between the intersection points of any two adjacent curves 42 and the intersection circle may be equal. Illustratively, the plurality of curves 42 may curve in the same direction, such as in a counterclockwise direction (as shown in fig. 8C), or in other embodiments not shown in a clockwise direction. Of course, each curve 42 may also have multiple directions of curvature, as shown in FIG. 8D, which illustrates that each curve 42 generally has a wave shape with two curves. In other embodiments not shown, each curve 42 may also be wavy with more curvature. Further, the bends may be uniformly distributed over each curve 42 or may be non-uniformly distributed over each curve 42. For example, portions closer to the central region 5 may be distributed with less bending, while portions farther from the central region 5The portions may be more curved.
Both rays 41 and curves 42 are formed by individual lines. Alternatively, instead of the ray 41 being also a curve 42, a plurality of first refractive regions and a plurality of second refractive regions may be distributed over a plurality of compound lines 43, as shown in fig. 8E. The plurality of composite lines 43 may be divergently distributed with respect to the central region 5. The composite line 43 may be formed from a plurality of straight lines, or from a plurality of curved lines, or from a combination of straight lines and curved lines. In the illustrated embodiment, the compound line 43 may include a main line extending in a radial direction of the ophthalmic lens and two branch lines extending outwardly from ends of the main line remote from a center of the ophthalmic lens. The plurality of composite wires 43 may be repeatedly arranged in the circumferential direction of the spectacle lens. That is, an intersection point m formed by an intersecting circle (see a broken line in the figure) centered on the center of the ophthalmic lens and corresponding portions on the plurality of compound lines 43 1 、m 2 …m n The distances between them are equal.
The ophthalmic lenses of the present application were found to score higher after extended wear in a questionnaire for patient comfort (table 1), including: whether the comfort level is double vision when wearing, whether the user feels tired, dizziness and headache or cannot adapt to the comfort level, whether the user walks on the way when wearing the novel lens or not feel any difficulty when wearing the novel lens, whether the user can go up and down stairs when wearing the novel lens, and the like (10 points are given to each item, finally, all the items are taken to be the average value, 10 points are given to the average value, and the comfort level is better when the score is higher). The comparative ophthalmic lens 1 does not have a radially continuous distance refractive correction zone.
