[Technical Field]

[0001] The present invention relates to an eyeglass lens design and an eyeglass lens kit for myopia control. The present invention relates to a computer-implemented method for designing an eyeglass lens and a method for manufacturing an eyeglass lens. Regarding. [Background technology]

[0002] The prevalence of myopia (nearsightedness) is rapidly increasing. Myopia can lead to retinal detachment (depending on the level of myopia) , significantly increases the risk of posterior polar cataract and glaucoma. because of the physical impact and the resulting inconvenience and costs to individuals and communities. to slow the progression, prevent or delay the onset of myopia, or to improve the condition of children and young people It would be desirable to have an effective strategy to limit the amount of myopia that occurs in both young and old adults.

[0003] The pamphlet of International Publication No. 2010 / 075319A2 describes the peripheral blood pressure that determines the incidence of myopia. The importance of retinal imaging is also mentioned. This paper aims to prevent, improve, or reverse axial length-related disorders. The present invention proposes a therapeutic treatment method for identifying eye length-related disorders in patients. and reducing the average spatial frequency of the image input to the retina of the eye above the threshold spatial frequency, thereby reducing the incidence of the disease. Induce artificial blurring of the patient's peripheral vision to prevent further axial elongation of the patient's eye. In particular, this document describes (i) bumps on the surface of spectacle lenses, (ii) (iii) a first semi-transparent inclusion within the spectacle lens material; and (i v) a first transparent inclusion in the spectacle lens material, the first transparent inclusion having a refractive index different from that of the spectacle lens material; a first transparent inclusion, It is suggested that the patient be provided with a lens. 2 Hit dot 0~ The spectacle lens includes a plurality of dot-shaped elements having a non-zero point density in eight ranges. The lens is surrounded by a zone that provides clear vision and another zone that provides clear vision.

[0004] Improvements to this type of spectacle lens are described in WO 2018 / 026697 A1. , International Publication No. 2019 / 152438A1 Pamphlet and International Publication No. 2020 / 01 These are disclosed in brochure No. 4613A1.

[0005] In particular, WO 2018 / 026697A1 discloses eyeglasses having frame-like features. and a pair of eyeglass lenses mounted on the frame, each of the eyeglass lenses having a Distributed in a dot pattern, the dot pattern being an array of dots spaced at a distance of 1 mm or less wherein each point has a maximum diameter of 0.3 mm or less.

[0006] The pamphlet of International Publication No. 2019 / 152438A1 describes a spectacle lens, a lens material having two oppositely curved surfaces and a scattering region surrounding a clear aperture. The scattering region includes a plurality of spaced apart scattering centers sized and shaped to scatter incident light. and the scattering centers have irregular variations in spacing between adjacent scattering centers and / or scattering center size. Spectacle lenses are disclosed that are arranged in a pattern that includes random variations.

[0007] For example, as disclosed in International Publication No. 2019 / 152438A1, The myopia-improving eyeglasses consist of an eyeglass frame and eyeglass lenses mounted on the eyeglass frame. Generally, spectacle lenses are classified into flat lenses, single vision lenses (e.g., lenses with positive or negative refractive power), and ) or multifocal lenses (e.g., bifocal or progressive lenses). Spectacle lenses may be: Each has a clear zone surrounded by a zone that provides contrast reduction. The lens is positioned to match the wearer's on-axis viewing position while providing contrast reduction. The zones that provide contrast reduction correspond to the wearer's peripheral vision. By scattering the light that reaches the wearer's eye through these zones, It consists of an array of dots that reduce the contrast of objects in the image. Convex and / or concave portions are formed on one or both sides of the mirror lens, and / or the level of these zones is This can be provided by forming scattering inclusions within the lens material itself.

[0008] The Hong Kong Polytechnic University and Hoya recently published U.S. Patent Application Publication No. 2017131567A1. In the specification, eyeglass lenses of similar structure, i.e., eyeglass lenses having bumps on the surface of the eyeglass lenses, are also used. These spectacle lenses are MSMD (Multi-Segment Myopia Defogger) lenses. Each technology concept is known as a DIMS (Defocus Integrated This is known as multi-segment technology.

These spectacle lens embodiments are disclosed in the specification of US Pat. No. 5,677,767. These spectacle lens embodiments are intended to correct myopia. The spectacle lens of such an embodiment is a meniscus concave lens. The front surface is formed as a convex surface that curves toward the object side, and the rear surface is formed as a convex surface that curves toward the object side. In addition, the spectacle lens is formed into a concave surface with a curvature greater than the curvature of the lens. a first zone having a first refractive power based on a prescription for correcting myopia; and a second zone surrounding the first zone and including a plurality of independent island-shaped areas.

[0009] The front surface of each island area in the second zone has a curvature greater than the front surface of the first zone. The second zone is formed in a convex spherical shape with a curvature that faces the object side. The refractive power of the island area is 2.00dpt to 5.00dpt higher than the refractive power of the first zone. Therefore, the image is formed on the retina of the eye by the first zone and The retina is connected to a point in front of it by an island-shaped area in the

[0010] Each island area is approximately 0.50 to 3.14 mm 2 Covers a diameter of approximately 0.8 The island areas have a circular shape with a radius of about 2.0 mm. The first and second zones are spaced apart from each other by a predetermined distance and are generally evenly spaced about the first zone.

This corresponds to the focal power, and the focal power of the eyeglass lens is assisted by accommodation to form an image on the fovea. Addition power, when added to the focal power of the spectacle lens, reduces myopic defocus. Addition power should not be confused with the addition power of progressive lenses. The add power of a progressive multifocal lens is the sum of the vertex power of the near portion of the spectacle lens and the vertex power of the distance portion of the spectacle lens. Specifies the difference between the vertex power and the

[0021] aperture For purposes of this specification, the term "aperture" includes (i) diffusing structures such as scattering centers; or (ii) surrounded by a zone containing one or more additional power structures. This corresponds to the zone for eyeglass lenses.

[0022] Wearing position The wearing position is the position of the spectacle lenses relative to the eyes and face during wearing ( DIN ISO13666:2019, Section 3.2.36). The forward tilt angle when wearing the glasses is determined by the front angle and the vertex distance. A vertical line passing through the apex of the grooves of the upper and lower rims of the frame in a vertical plane containing the main direction. is the perpendicular angle between a line and a plane (DIN ISO13666:2019, Section 3.2. 37), the principal direction is measured with the habitual head and body position when looking straight ahead with the naked eye.

Typical values ​​for the forward tilt angle during wear range from -20 to +30 degrees. The front angle when wearing the glasses is the angle between the main direction and the nose side of the frame in the horizontal plane including the main direction. The horizontal angle between the rim and the perpendicular line to the reference line passing through the apex of the groove of the temple side rim (DI N ISO13666:2019, Section 3.2.38). Typical front angles when worn Typical values ​​are in the range of -5 to +30 degrees. The vertex distance is measured with both eyes in the primary position.

The position may be an individual wearing position specified by the user or a general wearing position specified for a defined group of users.

[0023] Without reference to the wear position, the power to be achieved using a spectacle lens design is inappropriately defined.

At least one section of the image should be positioned on the fovea, assisted by adaptation if necessary. For example, when the wearer looks through each zone, the focus is on the central vision and the near vision. Glasses that provide neither visual defocus nor diffusion but exhibit residual astigmatism errors that lead to blurred images There may be zones of a lens design or spectacle lens. Such zones are used herein as In this example, a section of the clear zone Only the lens allows for imaging on the fovea. The area that allows the above imaging to be achieved may cover the entire clear zone.

The term refers to an optimization process aimed at achieving a target optical spectacle lens design as close as possible to the target. means the spectacle lens with calculated optical properties received as a result of a calculation. Such optimization process in progressive or customized single vision lenses / The calculations are carried out, for example, by Werner Koeppen:Konzeption und En twicklung von Progressivglaesern, in Deut sche Optiker Zeitung DOZ 10 / 95,S.42-46 is shown.

[0049] Such optical or geometric spectacle lens designs may be computer readable (e.g., non-transitory, The data can be stored on a data carrier (electronic and / or optical). The resulting spectacle lens can be considered a physical representation of the spectacle lens design.

[0050] The basic steps of an example method for designing an eyeglass lens are outlined below: In a first step, the individual user data or application data of the spectacle wearer is collected. This allows for the collection of (physiological) data that can be assigned to the spectacle wearer. and obtaining the conditions of use under which the spectacle wearer will wear the designed spectacles.

[0051] The physiological data of the spectacle wearer include, for example, the wearer's refractive error and the wearer's ability to accommodate. These are determined by refraction measurement means and usually include sphere, cylinder, axis, and prism. The prescription includes prescription values ​​for the base, add and center powers. Pupil size was determined under various lighting conditions. Wearer age has a significant effect on accommodative ability and pupil size. The focusing behavior of the eye affects the vision of different visual fields, and therefore the age of the wearer can also be taken into account. It arises from the interpupillary distance in the direction and object distance.

[0052] The conditions of use are the position of the spectacle lens in front of the eye (usually related to the pivot point of the eye) and , and the object distance in various viewing directions that the spectacle wearer should see clearly. The sheet of lenses may be measured, for example, by recording the vertex distance and anterior and lateral tilt. These data can be used to identify the location of the object. It is included in the object distance model.

[0053] In a subsequent step, a draft design of the spectacle lens with a number of evaluation points is generated from this record. The draft design is determined based on the data obtained. Target optical characteristics include, for example, the placement of the lens in front of the eye and the basic distance model. Distributed over the entire spectacle lens, taking into account the add power, as specified by Dell This includes the allowable deviation from the prescribed spherical and astigmatic powers.

[0054] Furthermore, the design of the surface geometry of the front and back surfaces and the refractive index distribution throughout the spectacle lens For example, the front surface can be chosen as a spherical surface and the rear surface as a variable focal surface. Both surfaces can be selected as spherical surfaces first. The choice of the draft surface geometry generally depends on the convergence (speed and performance) of the optimization method used. For example, the front surface should maintain a spherical shape, and the rear surface should have a variable focal plane shape. It should be assumed that the condition is given.

[0055] In a further step, the course of the chief ray is identified through a number of evaluation points. In this case, a local wavefront can be established for each chief ray in the vicinity of each chief ray. er Koeppen: Design and Development of Pro gressive Lenses,Deutsche Optiker Zeitung According to DOZ 10 / 95, pp.42-46, the number of evaluation points is usually between 1000 and 1 In European Patent No. 2 115 527 B1, the range is over 8000. The refractive index is usually wavelength dependent, but dispersion is generally However, the optimization process is not considered and the calculation is carried out at the so-called design wavelength. It cannot be excluded to take into account the design wavelength, e.g. as described in EP 2 383 This is described in specification No. 603B1.

[0056] In a subsequent step, the above-mentioned optical properties of the spectacle lens at the evaluation point are measured by the beam of the chief ray. Identify the influence of the spectacle lens on the system path and, if necessary, on the local wavefront in the vicinity of each evaluation point. It is identified by:

[0057] In a further step, the design of the spectacle lens is based on the identified optical characteristics and the individual user's The data is evaluated according to the refraction of the back geometry and possibly the design of the spectacle lens. The rate distribution is, for example,

number

[0058] In other words, the local surface geometry of the rear surface and possibly the eye in each visual beam path. The local refractive index of the mirror lens is varied by evaluation point until a termination criterion is met.

[0061] viewing angle The term "visual angle" refers to the angular distance between two points in the field of view.

[0062] width The term "width" refers to the horizontal dimension of a structure, in particular a spectacle lens or eyeglasses, in a given wearing position. This refers to the horizontal dimension of the zone in the lens design, especially in the case of curved structures, which is located most nasally. This means the absolute value of the difference between the point of the structure closest to the temple and the point of the structure closest to the temple.

[0103] Exemplary embodiments of eyeglass lenses based on the lens design according to the present invention are shown in FIGS. 1 to 6. The spectacle lens of the exemplary embodiment has a first zone and a second zone. and a second zone at least partially surrounding the first zone. When worn, the lenses are curved to follow the wearer's convergent line of sight.

[0104] In an alternative embodiment, the width of the first zone is at least four times the height of the first zone. However, in some exemplary embodiments, the first zone spans the entire width of the spectacle lens, i.e., The first zone extends from the temple rim of the spectacle lens to the nose rim of the spectacle lens. In these exemplary embodiments, the second zone partially overlaps the first zone. The first zone encloses only the first one and is divided into two separate sub-zones. The present invention relates to a spectacle lens in which the first zone is positioned off-center and the first zone is curved. However, the first zone described in the exemplary embodiment The locations and geometries of the first zones are not exclusive. Each first zone should be at least four times as wide as it is high. Those skilled in the art will envision additional possible locations and geometries for the first zone having .

[0105] A first exemplary embodiment of an eyeglass lens design according to the invention will now be described in relation to FIG. 1 shows a pair of eyeglasses manufactured according to a first exemplary embodiment of an eyeglass lens design according to the present invention. The spectacle lens 2 is a first exemplary embodiment of a pair of eyeglasses 1 with a plan view. It can be considered a representative of mirror lens design.

[0106] In this exemplary embodiment, the eyeglasses 1 are comprised of two single lenses, one for the wearer's right eye and one for the wearer's left eye. The eyeglasses are provided with two eyeglass lenses 2. The two eyeglass lenses 2 are attached to an eyeglass frame 3. The spectacle lens 2 is separated by a bridge 7 of the frame 3. Due to the myopic wearer, the spectacle lens 2 is worn The spectacle lens 2 is designed to provide a perfect correction according to the patient's prescription. It is an inas lens.

[0107] Each spectacle lens 2 comprises a first zone 4 which is similar to a clear zone for viewing objects. In other words, the first zone 4 provides a clear image to the foveal zone of the retina of the wearer's eye. do.

[0108] This first zone 4 spans the entire width of the spectacle lens 2, i.e. has an overall dimension d v and is vertically surrounded by a second zone, which in this exemplary embodiment In the embodiment, there are two sub-zones, zone 5, separated from each other by a first zone 4. The sub-zones 5a and 5b provide scattering optical properties. Thus, the second zone of this exemplary embodiment, i.e. its sub-zones 5a, 5b, is divided into two The diffuser zone is formed with the diffuser subzones 5a, 5b of the second zone. b is stripe-shaped and has a plurality of dot-shaped scattering centers 6. Scattering in physics is Generally, it is understood to mean the deflection of an object through interaction with another local object, i.e., a scattering center. It is understood that in this case the scattering does not lead to a predetermined focusing or multiple predetermined focusing, but to a clumping of light. providing the wearer with reduced contrast compared to viewing through the rear first zone 4 It shall mean any non-directional deflection of input light.

[0109] In this exemplary embodiment, the height of the first zone 4 is equal to the height of the sub-zone 5a of the second zone. 5b, and the spectacle lens 2 is worn according to the dedicated wearing position. When used in conjunction with a 12-inch display, the display is selected to provide a vertical viewing angle of approximately 1.2 degrees. The first zone 4 extends over the entire width of the spectacle lens 2. Due to this, the clear vision of the characters in the line is not obstructed by the second zone, and the reader For example, International Publication No. 2010 / 075319A2, International Publication No. Brochure No. 2018 / 026697A1, International Publication No. 2019 / 152438A1 Described in the pamphlet and WO 2020 / 014613A1 pamphlet, respectively Improved comfort compared to current state-of-the-art spectacle lenses with a circular zone of clear vision, such as Fall.

[0110] The first zone 4 is arranged towards the nose segment 4a, i.e. the nose rim 8 of the spectacle lens. the temple segment 4b, i.e. towards the temple-side rim 9 of the spectacle lens. a segment disposed between the nose segment 4a and the temple segment 4b; The first zone 4 includes a nasal segment 4a and a temple segment 4c. The first zone 4b is bent so that the first zone 4b is shifted downward relative to the central segment 4c. The curvature of the lens 4 is determined by the wearer's front view at the reading distance from the wearer's retina. If you hold a book on a flat surface and move your eyes from left to right as you read the lines, reading at close range The curved first zone 4 is adapted to the wearer's line of sight. The height of the text allows only enough vertical viewing angle to make 12pt text legible. Even in this case, due to the diffusion induced by the second zone 5a, the eye movement when reading the lines During this time, it is possible to avoid a decrease in contrast for a portion of the line currently being read.

[0111] A second exemplary embodiment of an eyeglass lens design according to the present invention will now be described in connection with FIG. 2 shows a pair of eyeglasses manufactured according to a second exemplary embodiment of the eyeglass lens design according to the present invention.

[0133] A sixth exemplary embodiment of an eyeglass lens design according to the present invention will now be described in connection with FIG. 6 shows a pair of eyeglasses manufactured according to a sixth exemplary embodiment of the eyeglass lens design according to the present invention. The spectacle lenses 52 are shown in plan view in a sixth exemplary embodiment. It can be considered representative of modern spectacle lens design.

[0134] In this exemplary embodiment, the eyeglasses 51 are made up of two pairs of glasses, one for the wearer's right eye and one for the wearer's left eye. The eyeglasses are provided with a single vision eyeglass lens 52. The two eyeglass lenses 52 are attached to an eyeglass frame 53. , separated by the bridge 57 of the spectacle frame 53. The lenses 52 are designed to provide full correction according to the wearer's prescription. The mirror lens 52 may be a minus lens.

[0135] Each spectacle lens 52 includes a first zone 54, which is similar to a clear zone for viewing objects. In other words, the first zone 54 provides a clear image to the foveal zone of the retina of the wearer's eye. This first zone 54 extends across the entire width of the spectacle lens 52, i.e., Overall dimension d vand is vertically surrounded by a second zone, e.g. In this exemplary embodiment, there are two sub-zones separated from each other by a first zone 54.

[0136] In this exemplary embodiment, the height of the first zone 54 is the sub-zone 55a of the second zone. and 55b, and the spectacle lens 52 is fitted according to the dedicated wearing position. When used, it is selected to allow a vertical viewing angle of about 1.0 degree. The first zone 54 is the area of ​​the eyeglass lens 52. Due to its full width, the clear view of the text on the line is not obstructed by the second zone. First, when reading, for example, the pamphlet of International Publication No. 2010 / 075319A2, International Publication No. 2018 / 026697A1, International Publication No. 2019 / 1524 38A1 and International Publication No. 2020 / 014613A1. In comparison with the state-of-the-art spectacle lenses with clear vision in a circular zone, as described Increase comfort.

[0137] In the sixth exemplary embodiment, the first zone 54 is a nose segment 54a, i.e., a spectacle lens. the segment disposed toward the nasal rim 58 of the lens, the temple segment 54b, i.e. A segment positioned towards the temple-side rim 59 of the spectacle lens, the nasal segment 54a The first zone includes a central segment 54c disposed between the first and second zones 54b and 54c.

It is also possible to use spectacle lenses having a lens design according to the invention. An exemplary embodiment of a method of manufacture is described in connection with FIG.

[0138] In a first step S1, data from a prescription is received, the prescription being based on the diagnosed refractive index. Contains a summary of the diopters needed to correct the error. For myopic eyes, the prescription is less It contains at least one spherical power value "sph". In addition, if astigmatism is added, the cylinder power It can also contain a value for the cylinder axis, such as a prism value. There may be further values ​​in the prescription such as: a second zone providing peripheral myopic defocus; If the prescription is to be used for peripheral myopic defocus, the prescription also includes the amount of add power used to provide However, in this exemplary embodiment, a diffuser zone is provided in the second zone. do.

[0139] In this exemplary embodiment, the values ​​contained in the prescription are administered by an optometrist to the patient. The measurements provide refractive data related to the patient's eye. objective refraction data, i.e., refraction data measured objectively by a refractometer or the like, or subjective refraction data In the case of subjective refraction data, this data may include any of the following: Try different test lenses and use text or eye charts of different sizes until you experience The data may be collected by having the patient view the data.

[0140] However, instead of prescription values, other suitable value forms, e.g., Zernike coefficient forms, may be used. Additionally, a refractometer or any other suitable measurement may be used to provide measurement data. It is also possible to receive values ​​representing objective refraction data directly from the device.

[0141] Based on the measurement data received in step S1, the wearer When viewed through worn eyeglass lenses, they provide an image on the fovea (aided by accommodation) In step S2, a monocular spectacle lens having a focal power is subjected to a suitable process. Suitable processes are, for example, molding processes or machining processes. If a machining process is used, the single vision lens can be obtained, for example, from a semi-finished blank. The semi-finished blank can then be manufactured, with the front surface already completed. The rear surface of the blank is designed to allow the semi-finished blank to become a monocular ophthalmic lens with the required focal power. It is machined like this.

[0142] In step S3, the scattering center is determined in the zone that will become the diffuser zone of the monocular spectacle lens, i.e. The second zone is introduced in a suitable manner, for example on the rear surface of the monocular eyeglass lens. by laser-generated point or line depressions in the The scattering centers may be such that the second zone at least partially surrounds the scattering center-free zone. Therefore, the scattering center-free zone is located on the fovea. The first zone has a focal power that provides imaging to allow clear vision. In other words, the shape and size of the first zone, in some cases, together with the rim of the spectacle lens, If the second zone completely surrounds the first zone, The height and width of the first zone are defined by the second zone. If one zone is enclosed only vertically, the height of the first zone is determined by the height of the second zone. The first zone is then rotated in three directions, while its width is given by the width of the spectacle lens. in a fourth direction by the rim of the spectacle lens. The second zone may be located above, below and nasally or above, below and nasally of the first zone. In some cases, the first zone may surround the outer side. In all cases, however, the first zone is Whether the second zone completely or partially surrounds the first zone, the glasses It can be seen as being defined by a second zone within the limits of the lens.

[0143] The scattering center is such that when the spectacle lens is placed according to the dedicated wearing position, the aperture is 0. A vertical viewing angle of 8 to 1.5 degrees, particularly 1.0 to 1.2 degrees, for example 1.0 or 1.2 degrees The scattering center is introduced so that it has a height that covers the corner. The scattering center is introduced so that it has a width at least four times its height. The aperture is located on at least one of the nose and temple rims of the eyeglass lens. It can be introduced so as to extend to

[0144] The second zone has focusing structures instead of scattering centers, so that the wearer can see through the first zone. If the focusing structure provides peripheral myopic defocus, an alternative step S3 is used. In this alternative step S3, the mold is set on the back surface of the monocular eyeglass lens, and the mold The molding surface of the mold represents the negative of the focusing structure to be produced. and the focusing structure is formed on the rear surface by injection molding or any other suitable molding process. After the molding process, a polishing process is performed to remove any ridges remaining from the molding process. However, applying a focusing structure to the rear surface of a monocular spectacle lens is It does not have to be done by a molding process, for example, oleic acid expansion or ink jet printing. Other processes may be used, such as additive manufacturing processes like print. In this embodiment, the focusing structure is formed on the rear surface, but could equally well be formed on the front surface of a monocular eyeglass lens. do.

[0145] After forming the second zone in step S3, i.e. providing a scattering center or focusing structure, After this, the eyeglass lens is completed.

[0146] For purposes of illustrating the invention, the concepts of the present invention have been described with reference to exemplary embodiments. However, it will be apparent to those skilled in the art that the concepts of the present invention can be implemented in variations of the exemplary embodiments. For example, it will be appreciated that the number and shape of the focusing structures may vary from those described in the exemplary embodiment. Additionally, those skilled in the art will appreciate that other fabrication techniques may be devised to provide a focusing structure. For example, instead of forming the focusing structure on the front or back surface of the spectacle lens, providing a zone in the spectacle lens with a refractive index different from that of the remainder of the spectacle lens; The provision of such a zone can be achieved, for example, by a doping process. As a result, the focusing structure is located on the surface of the spectacle lens, rather than on the surface of the spectacle lens. Therefore, the present invention is not limited by the exemplary embodiments. The present invention is not limited to the scope of the present invention, but is limited only by the scope of the appended claims.
