Description

Technical Field

[0001] The present disclosure relates to the field of ophthalmic equipment, and in particular to a pair of eyeglasses and frame glasses based on a linear layout, which are intended to be worn in front of a person's eyes to inhibit the progression of myopia. Background Art

[0002] Traditional lenses mainly seek to correct vision for eyes that already have refractive errors. This type of lens is used as a form of relief to solve the defects of the eyes. After people wear this type of lenses (such as single-vision lenses), their vision will inevitably deteriorate further (such as myopia further deepens). People hope to actively control refractive errors (such as myopia, hyperopia, etc.) to prevent further deterioration of vision. Therefore, spectacle lenses are developing new functional lenses with myopia control effects based on traditional single-vision lenses.

[0003] With the development of technology, Professor Du Sihe of the Hong Kong Polytechnic University in China first developed a defocus lens. The basic mechanism of this defocus lens is to form myopic defocus within a certain viewing angle range outside the wearer's fovea, thereby stimulating the eye's axial length to slow down or stop growing. After clinical verification, the defocus lens proposed by Professor Du was confirmed to have a certain effect in preventing and controlling myopia. Subsequently, defocus lenses have shown diversified development. Figure 1-5 It shows a variety of eyeglass lenses that have been put on the market or have completed research and development. Figure 1 The "New Lexic" spectacle lens developed by the Hong Kong Polytechnic University and the Hoya Corporation of Japan is shown, which adopts a "multi-zone positive optical defocus design". 396 microlenses are evenly arranged in the circumference of the central area of ​​the spectacle lens. The central area and the area between the microlenses allow light to fall on the retina, and the microlenses are used to form a near plane defocus zone to control the wearer's myopia.

[0004] Figure 2 The "Little Happy Circle" spectacle lens of Zeiss Company is shown, which adopts "concentric annular micro-column technology". The spectacle lens is provided with a plurality of annular cylindrical micro-structures with different radii on the outside of the central optical area. These annular cylindrical micro-structures are nested and arranged in a concentric circle manner to form annular micro-structure distribution areas. The spectacle lens introduces high-order aberrations and myopic defocus along the radial meridian direction in the peripheral visual field of the retina through these annular micro-structure distribution areas, thereby achieving the purpose of myopia control.

[0005] In addition, there are Figure 3 The "Star Fun" eyeglass lenses developed by Essilor of France are shown. Figure 4The "Ola" spectacle lenses developed by Fitlan in Israel are shown. The surfaces of these spectacle lenses have different microlens diopters and arrangements. However, through observation, it can be found that the various array designs of microlenses in these newly developed lens designs achieve equivalent defocus in the circumferential direction of the retina.

[0006] There is evidence that these concentric circle or discrete micro-lens lenses can indeed delay and control myopia to a certain extent. However, as the wearing time of the lenses increases, the wearers will gradually adapt to and compensate for the single form of defocus stimulation provided by the lenses (micro-lenses), resulting in the weakening of the myopia prevention and control effect of the lenses year by year.

[0007] Therefore, there is an urgent need for a spectacle lens that can provide a continuous and effective myopia suppression effect for patients with refractive errors. Utility Model Content

[0008] In view of the above-mentioned status of the spectacle lenses according to the prior art, one of the objectives of the present disclosure is to provide a spectacle lens that can provide effective myopic defocus stimulation to the wearer over a longer period of time.

[0009] The object is achieved by disclosing a spectacle lens in the following form. The spectacle lens is a spectacle lens based on a linear layout, comprising:

[0010] an optical zone forming a base surface of the spectacle lens and having a prescription refractive power based on an eyeball, the optical zone including a central optical zone located in a central area of ​​the spectacle lens and a peripheral optical zone located in a peripheral area of ​​the spectacle lens; and

[0011] a control zone, the control zone being located between the central optical zone and the peripheral optical zone, the control zone comprising:

[0012] a first lens array, the first lens array continuously spirally extending from the central optical zone to the peripheral optical zone, the first lens array comprising a plurality of first lenses having regular polygonal surfaces and in surface contact with each other, wherein a line connecting the centers of the plurality of first lenses forms a spiral line formed by sequentially connecting a plurality of first straight line segments; and

[0013] a second lens array, the second lens array extending linearly from the central optical zone to the peripheral optical zone, the second lens array comprising a plurality of second lenses having regular polygonal surfaces and in surface contact with each other,

[0014] The first lens and the second lens have additional optical power compared to the prescribed optical power.

[0016] Preferably, the first lens array comprises an inner ring lens group adjacent to the central optical zone, and a line connecting the centers of the first lenses of the inner ring lens group defines a hexagonal shape.

[0017] Preferably, the hexagon defined by the inner ring lens group is a hexagon with three groups of parallel sides.

[0018] Preferably, opposite sides of the hexagon defined by the inner ring lens group are of unequal lengths.

[0019] Preferably, the same first straight line segment passes through the centers of at least three first lenses.

[0020] Preferably, the control zone includes a plurality of the second lens arrays, and the plurality of the second lens arrays are arranged at different circumferential positions of the control zone.

[0033] Next, the disclosed concept of the present disclosure will be described in detail with reference to the accompanying drawings. Described here are only preferred embodiments according to the present disclosure, and those skilled in the art may think of other ways to implement the present disclosure on the basis of the preferred embodiments, and the other ways also fall within the scope of the present disclosure. In the following specific description, directional terms such as "upper", "lower", "inner", "outer", "longitudinal", "horizontal", etc. are used with reference to the directions described in the accompanying drawings. The components of the embodiments of the present disclosure can be placed in a variety of different directions, and the directional terms are used for illustrative purposes and are not restrictive.

[0034] In the present disclosure, the spectacle lens 1 is a spectacle lens 1 suitable for being worn in front of a person's eyes. The spectacle lens 1 is not attached to the surface of the eyeball, but is mounted in front of the eye through a metal frame or a plastic material frame.

[0035] Figure 5-71 and 2 show the eyeglasses 1 based on the linear layout according to the first preferred embodiment to the third preferred embodiment of the present application, respectively. The eyeglasses 1 include an optical zone 10 and a control zone 20, etc. Figure 5 In the embodiment of the spectacle lens 1 shown, the spectacle lens 1 has a substantially circular surface shape. Alternatively, the spectacle lens 1 may also have a rectangular, square or other special-shaped surface shape.

[0036] Unless otherwise specified, the "surface shape" in the present disclosure refers to the shape defined by the outer edge of the object as a whole or a local area of ​​the object when observed along the normal direction of the center of the object or a local area of ​​the object.

[0037] The optical zone 10 of the spectacle lens 1 forms the base surface of the spectacle lens 1 and has a prescription refractive power based on the eyeball. The base surface can be a rotationally symmetrical spherical form or an aspherical form, or it can be a non-rotationally symmetrical cylinder or a sphero-cylindrical surface. The non-rotationally symmetrical cylinder or sphero-cylindrical surface can have different curvatures in four quadrants. The optical zone 10 includes a central optical zone 11 located in the central area of ​​the spectacle lens 1, and a peripheral optical zone 12 located in the peripheral area of ​​the spectacle lens 1. The edge of the central optical zone 11 is preferably configured to correspond to a 10-12° viewing angle of the wearer. For children, the radius r of the inscribed circle of the central optical zone 11 can be set at 3 mm to 8 mm. Among them, the inscribed circle of the central optical zone 11 can be referred to Figure 5 The central optical zone 11 is indicated by a dotted line.

[0038] The control area 20 is located between the central optical zone 11 and the peripheral optical zone 12. The control area 20 includes a first lens array 21 and a second lens array 22. The first lens array 21 extends continuously and spirally from the central optical zone 11 to the peripheral optical zone 12. The first lens array 21 includes a plurality of first lenses 21A having regular polygonal surfaces and in contact with each other, wherein the line connecting the centers of the plurality of first lenses 21A forms a spiral line formed by sequentially connecting a plurality of first straight line segments. The spiral line can be seen Figure 5-7 The dashed line segments of the generally spiral lines in FIG.

[0039] The second lens array 22 extends straight from the central optical zone 11 to the peripheral optical zone 12, and includes a plurality of second lenses 22A having regular polygonal surfaces and in surface contact with each other. A plurality of second lens arrays 22 may be provided in the control zone 20, and the plurality of second lens arrays 22 are provided at different circumferential positions of the control zone 20.

[0040] Figure 5-7 In the embodiment, the area between the first lens array 21 and the second lens array 22 is a correction area 24, and the correction area 24 has a prescribed refractive power. Figure 5-7As shown, the correction zone 24 may be a region formed by combining a plurality of microlenses having prescribed refractive powers through surface contact.

[0041] The first lens 21A and the second lens 22A have additional refractive power compared to the prescribed refractive power. The additional refractive power can be set within ±5D, such as +3D, -2D, etc.

[0042] In order to ensure that the defocused area in the control area 20 where the first lens 21A and the second lens 22A are arranged has a larger total area, the radially adjacent first lenses 21A have a smaller spacing in the spiral line defined by the first lens array 21. The spacing may be, for example, preferably as follows: Figure 5-7 The spacing is shown as 1 times the side length of the first lens 21A, or other spacings are not shown, such as 0.5-1.5 times the side length of the first lens 21A.

[0043] In the scheme of the present application, "linear layout" refers to the use of straight line layout. For example, in the spiral line defined by the first lens array 21 in the present application, each first straight line segment constituting the spiral line is a straight line defined by the centers of several first lenses 21A; and each second lens 22A of the second lens array 22 is a straight line defined by the centers of several second lenses 22A. The first lens array 21 and the second lens array 22 are both partial components of the linear layout in the eyeglass lens 1 of the present application.

[0044] In the above eyeglass 1, the first lens array 21 which is non-circular and has a linear layout can provide frequent dynamic stimulation changes of "generating defocus stimulation" and "escaping from defocus stimulation" to different areas of the eye during various forms of eye rotation of the wearer. Combined with the design of the second lens array 22 which extends linearly from the central optical zone 11 to the peripheral optical zone 12, when the wearer rotates his eyes, the eyes are also subject to dynamic defocus stimulation caused by the change in the total area of ​​the circumferential first lens 21A and the second lens 22A, which further increases the defocus stimulation. The combination of the above first lens array 21 and the second lens array 22 thus achieves a relatively good dynamic defocus stimulation effect, ensuring that the wearer can achieve a continuous and effective myopia control effect by wearing the eyeglass 1 for a long time.

[0045] In the illustrated example, in the eyeglass 1 , at a position where the first lens array 21 and the second lens array 22 intersect each other, the first lens array 21 and the second lens array 22 share the first lens 21A or the second lens 22A.

[0046] Preferably, in the first lens array 21, it includes an inner ring lens group 25 adjacent to the central optical zone 11. The lines connecting the centers of the first lenses 21A of the inner ring lens group 25 define a hexagonal shape. More preferably, the hexagon defined by the inner ring lens group 25 is a hexagon with three sets of parallel sides, such as Figure 5-7 shown.

[0047] Preferably, if Figure 5 , 6 As shown, the hexagon defined by the inner ring lens group 25 is in a manner in which the relative sides of each group are not equal in length. This asymmetric design is more conducive to providing different defocus stimuli to the wearer during the process of rotating his eyes.

[0048] For the same segment, the first straight line segment is defined by the center of the first lens 21A, which is preferably set to pass through the center of at least 3 first lenses 21A. The diameter of the circumscribed circle of the first lens 21A can be selected as any value in the range of 0.6mm-2.5mm as in the prior art. The first lens 21A can be optionally Figure 5-7 The shape of the regular hexagon shown, or the shape of a regular pentagon, regular octagon, etc. not shown.

[0049] In the case where the second lens array 22 is provided in plurality, the second straight line segment defined by the center of the second lens 22A of at least part of the second lens array 22 is provided at the end of the first straight line segment or adjacent to the end of the first straight line segment. The second lens 22A and the first lens 21A located at the intersection of the second lens array 22 and the first lens array 21 have the same surface shape. Figure 5-7 It can be seen that the end of the first straight line segment and the position near the end correspond to the corners on the corresponding spiral line of the first lens array 21. By making the above design at these corners, when the wearer turns his eyes to see objects, the excessive visual difference caused by the line of sight passing through these corners can be avoided, thereby reducing the possibility of dizziness of the wearer.

[0050] See also Figure 6 In a preferred embodiment, the control area 20 is further provided with a third lens array 23. The third lens array 23 includes a plurality of third lenses 23A that are in contact with each other and form a Y shape. The lower end of the Y shape is composed of at least one first lens 21A and is protruded toward the central optical area 11 by an inner ring lens group 25 (see Figure 6 The third lenses 23A protrude from the inner ring lens group 25. These third lenses 23A (array) are arranged at the edge position corresponding to the central optical zone 11, so that the edge of the central optical zone 11 is extended, which will help to provide more effective defocus stimulation for the wearer's eyes.

[0051] The third lens array 23 may be evenly arranged in a plurality of numbers, such as 3, 5, etc., on the circumference of the inner ring lens group 25. Figure 6 In the example, each third lens array 23 includes seven third lenses 23A, and four of the seven third lenses A are first lenses 21A shared with the first lens array 21 .

[0052] The third lens 23A may be configured to have the same surface shape and refractive power as the first lens 21A and the second lens 22A.

[0053] The control area 20 can form a uniform diffuse light spot, so that the wearer of the spectacle lens 1 forms a blurred peripheral visual image, thereby preventing the eyeball from being stimulated by the outside world.

[0054] It should be noted that, although not shown, the eyeglass lens 1 is actually provided with any form of mechanism or structure such as a groove, a through hole, a protrusion, etc. near its outer edge and / or at its outer edge for fixing it. These mechanisms or structures are used to fix the eyeglass frame, etc., which are not the innovation of the present disclosure. Whether these contents are disclosed or not does not affect the feasibility of the present disclosure. Here, this article does not elaborate on them.
