Description

Technical Field

[0001] The invention relates to a spectacle lens, a contact lens, a frame spectacles, a method for manufacturing the spectacle lens and a peripheral imaging interference device. Background Art

[0002] The main reason for the increase in myopia is the extension of the eye axis. Every 1mm of extension increases the degree of myopia by 3.00 degrees. The latest medical research confirms that the extension of the eyeball depends on the peripheral defocus of the retina. According to the concept of refraction, Figure 1 , where 10 is the retina, as shown by 30, the focus falling in front of the retina is called myopic defocus, and as shown by 20 in the figure, the focus falling behind the retina is called hyperopic defocus. The central part of the retina of myopia is myopic defocus, while the peripheral part of the retina is hyperopic defocus. This hyperopic defocus of the peripheral retina is the main reason for the continuous increase of myopia.

[0003] The eyeball has the characteristic of relying on peripheral retinal imaging to induce eyeball development, especially for myopia in adolescents under 18 years old. If the peripheral retinal imaging is hyperopic defocus, the retina will tend to grow toward the image point, and the length of the eyeball will be extended. If the peripheral retinal imaging is myopic defocus, the eyeball will stop extending. If modern medical methods are used to correct peripheral retinal hyperopic defocus or artificially form peripheral retinal myopic defocus, the degree of myopia can be stopped from increasing, the cause of peripheral retinal defocus can be identified, and the occurrence and progression of myopia can be effectively prevented.

[0004] Myopic peripheral defocus can control the growth of myopia in adolescents, which is now a well-recognized effective control mechanism in the field. Based on this, a variety of technical solutions for myopic peripheral defocus have been formed, including orthokeratology lenses, multifocal contact lenses, peripheral defocus frame glasses, etc. Such technologies are disclosed in US7025460, CN110554515A, CN106707542B, CN110376758A, CN109946849A, etc.

[0005] Among these technical solutions, orthokeratology lenses and multifocal contact lenses have shown a relatively definite myopia control effect in clinical practice. Orthokeratology lenses can delay the growth of myopia by about 40% to 60%; multifocal contact lenses can slow down the progression of myopia by 30% to 38%, and axial elongation by 31% to 51%.

[0006] However, frame glasses that also use peripheral defocus design technology have no significant effect. Clinical statistical results show that there is no significant difference in the effect on the eye axis compared with ordinary frame glasses.

[0007] This may be related to the continuous change in eye position when viewing through the lens. The retina is a sheet of cells at the back of our eyeballs. Among these cells, some are called photoreceptors, which are very sensitive to light. There are mainly two types of photoreceptors: rod cells are sensitive to the difference in light and dark, while cone cells are more sensitive to colors. These photoreceptors are most densely packed in a small area at the center of the retina called the "fovea". It corresponds to the center of our visual field, where the resolution is the highest. The farther away from the fovea, the more blurred the details of the visual field become, which is the so-called peripheral vision. When we look around, we move our eyes. This allows us to direct the fovea to the area of greatest interest within the nearby range. These voluntary eye movements are called eye saccades and are completed approximately three times per second. Our brain corrects the eye movements by controlling the eye muscles. Since the brain omits the information during eye movement, most of our visual world is in a fixation state, and this time period is relatively short, about 200 - 300 milliseconds long. After investigating the data, it is found that our eyes are in a moving state for 10% - 20% of the time.

[0008] For peripheral defocus control technologies such as orthokeratology lenses and contact lenses that are synchronized with eye movements, generally, the eye movements do not change the peripheral defocus state formed by the human eye optical system relative to the retina. Therefore, the myopic peripheral defocus formed is stable. However, for frame glasses with a peripheral myopic defocus design, eye movements will cause changes in the defocus states of the fovea and the peripheral area. As Figure 2 shown, when the eyeball 100 is in the orthophoric viewing state, due to the design structure of the lens 200, the refractive power of the peripheral area is greater than that of the central area. Therefore, the central light ray 01 falls on the retina, while the peripheral light rays 02 and 03 fall in front of the retina, forming myopic peripheral defocus. This is the original intention of the designer and also the ideal state.

[0009] But if the eyeball moves and its position changes relative to the frame glasses, the imaging is as Figure 3 shown. The peripheral light ray 02 becomes the central light ray in the new optical system and may form a certain degree of myopia, while the originally central light ray 01 becomes the peripheral light ray in the new system. Since its refractive power is smaller than that of the periphery, it may form hyperopic peripheral defocus. This is the main problem that frame glasses with the current myopic peripheral defocus design cannot well control the development of myopia. The technologies described in the above patent documents and the like all have such problems and cannot produce good myopia control effects. Summary of the Invention

[0010] The object of the present invention is to provide a spectacle lens, a frame glasses, a manufacturing method of the spectacle lens, and a peripheral imaging interference device that are helpful for improving the myopia control effect.

[0011] To achieve the above object, the spectacle lens of the present invention is a peripheral myopic defocus lens, with a peripheral imaging interference area provided outside the central optical zone, and an imaging interference part and a transparent gap part located between different parts of the imaging interference part are formed in the peripheral imaging interference area.

[0012] With the above structure, since an imaging interference part is formed in the peripheral imaging interference area, the peripheral part of the peripheral myopic defocus lens is regionalized and blurred. During the process of the brain autonomously selecting the fovea to direct to the most interesting area within the nearby range, due to the characteristic of blurred imaging in the peripheral part, when the human eye looks around, the behavior mode changes from moving the eyes to moving the head, thereby solving the problem of unstable defocus state caused by the rotation of the human eye when viewing objects through the peripheral myopic defocus lens, keeping the human eye and the lens system in the centered position all the time, forming a more stable myopic peripheral defocus, and obtaining the expected myopia control effect.

[0016] Preferably, the imaging interference part forms a dot pattern, a grid pattern, a plurality of concentric circular patterns or a plurality of fan-shaped patterns.

[0017] In addition, the imaging interference part can be provided on the front surface of the spectacle lens, or on the back surface, or on both surfaces.

[0018] In addition, the present invention also relates to a pair of frame glasses having the spectacle lens with any of the above structures.

[0019] Furthermore, the present invention also relates to a manufacturing method of a spectacle lens. The spectacle lens is a peripheral myopic defocus lens, with a peripheral imaging interference area provided outside the central optical zone, and an imaging interference part and a transparent gap part located between different parts of the imaging interference part are formed in the peripheral imaging interference area. The manufacturing method includes the following processes: a. Obtain a raw material lens with a peripheral myopic defocus structure; b. Form the peripheral imaging interference area outside the central optical zone of the obtained raw material lens.

[0020] Preferably, in the process b, the peripheral imaging interference area is formed by means of film patching, coating, machining, etching, lithography, scribing or printing and dyeing.

[0021] In addition, the present invention also relates to a peripheral imaging interference device, which is used in combination with a peripheral myopic defocus lens. It has a transparent central area and a peripheral area located outside the central area. In the peripheral area, there are imaging interference parts and transparent gap parts located between different parts of the imaging interference parts.

[0031] <The First Embodiment>

[0032] This embodiment relates to a spectacle lens (sometimes simply referred to as a lens) of a framed spectacle and a framed spectacle having the spectacle lens. On the basis of a lens with a peripheral myopic defocus structure, a peripheral imaging interference area is provided outside the central optical area. The central optical area is an imaging area corresponding to the pupil with a diameter of 5 mm to 15 mm, preferably in the range of 5 mm to 10 mm, and serves to form a clear image. The peripheral imaging interference area is an area with a diameter of 5 - 30 mm, preferably 10 - 20 mm, outside the central optical area, and has patterns and designs formed by imaging interference portions, which serve to interfere with the continuous and clear imaging of the periphery of the lens and prevent the human eye from directly gazing at the image through the peripheral area. The overall imaging interference portion can be formed into various shapes of patterns, designs, letters, lines, etc. The pattern of the peripheral imaging interference area can be regular or irregular. The shape of the imaging interference portion itself can also be freely designed, such as dot-shaped, square-shaped, diamond-shaped, etc.

[0033] Figure 4 Examples of the patterns formed by the imaging interference portions are shown. In Figure 4 A of, the imaging interference portions are dot-shaped, there are multiple of them, and they are arranged in a staggered matrix. In addition, the circular blank area in the center of the figure corresponds to the above-mentioned central optical area, and this is the same in Figure 4 B - F of. In Figure 4 B of, the imaging interference portions are dot-shaped, there are multiple of them, and they are arranged in a grid pattern. In Figure 4 C of, the imaging interference portions are diamond-shaped, there are multiple of them, and the whole is arranged in a dot matrix pattern. In Figure 4 D of, the imaging interference portions are circular ring-shaped, there are multiple of them, and they are arranged concentrically. In Figure 4 E of, the imaging interference portions are fan-shaped, there are multiple of them, and they are arranged circumferentially. In Figure 4 F of, the imaging interference portions are heart-shaped, there are multiple of them, and they are arranged circumferentially. In Figure 4 A - F of, there are multiple independent and discontinuous imaging interference portions. However, the present invention is not limited to this, and the imaging interference portion can be a continuous part, such as shown in Figure 4 G of.

[0034] The overall pattern formed by the imaging interference portions cannot be completely continuous and occlusive, that is, in the peripheral imaging interference area, there are transparent gap portions between different parts of the imaging interference portions. The transparent gap portions allow peripheral light to pass through and form an image at a position outside the fovea of the retina, forming peripheral defocus.

[0035] Here, the so-called "different parts of the imaging interference portion" includes both the meaning between different parts of multiple imaging interference portions and the meaning between different parts of one imaging interference portion.

[0036] The imaging interference part of the peripheral imaging interference area can be transparent, opaque, or colored. The pattern of the peripheral imaging interference area can be achieved by means such as thin-film patching, coating, machining, etching, lithography, scribing, printing and dyeing, etc., and can also be achieved by changing the refractive index, light transmittance, etc. of the lens material in the peripheral imaging interference area. These methods can also be said to be the formation methods of the imaging interference part. In addition, regarding the method of using thin-film patching, the thin-film patch can be cut into the shape of each imaging interference part and pasted on the spectacle lens, or the thin-film patch can be cut into a shape roughly consistent with the spectacle lens, and then the imaging interference part is formed on the thin-film patch by means such as coating, machining (hollowing out, etc.), etching, lithography, scribing, printing and dyeing, etc.

[0037] In addition, methods such as coating, machining, etching, lithography, scribing, printing and dyeing, etc. can be directly implemented on the spectacle lens to directly form the imaging interference part on the spectacle lens without the need for a thin-film patch.

[0038] The imaging interference part is preferably in the form of a slightly frosted, translucent pattern or pattern. In this way, while being able to play an optical interference role, it is not easily noticed by the naked eye that there is an obvious appearance difference from an ordinary lens.

[0039] In addition, the imaging interference part can be set on the front surface of the lens, or on the back surface of the lens, or on both surfaces.

[0040] <Example 1>

[0041] (1) Lens parameters: The peripheral defocus control frame glasses are made in the manner of US7025460. Its lens is composed of front and back surfaces. The central thickness of the lens is 3 mm, the refractive index of the material is 1.517, the radius of curvature of the back surface is 75 mm, the front surface is aspherical, the radius of curvature is 134.6, and the surface shape satisfies the equation s = a1 * x 2 + a2 * x 4 + a3 * x 6 , where s is the axial height (unit: mm) of different positions on the front surface from the vertex, x is the position in the diameter direction of the lens, unit: mm, a1 = 0.003312, a2 = 2.053 * 10 -6 , a3 = -6.484 * 10 -9 . This lens will correct myopia for patients with a myopia degree of -3D and provide myopic peripheral defocus in the orthophoric position.

[0042] (2) Using chemical materials, draw 4 circles with the center of the optical zone as the center, with diameters of 10 - 11 mm, 12 - 13 mm, 14 - 15 mm, and 16 - 17 mm. After the chemical etching is completed, wash away the chemical materials. The lens will leave 4 annular imaging interference parts in the chemically etched area, presenting a frosted glass form. Thus, a peripheral imaging interference zone is formed outside a diameter of 10 mm, while within a diameter of 10 mm in the center, clear vision is still possible. As Figure 4 shown in D. The etched part can be on the front surface of the lens, on the back surface of the lens, or distributed on both surfaces.

[0043] After the lens is processed, within a diameter of 10 mm in the center is still a clear imaging optical zone, through which the human eye can see normally. The peripheral myopic defocus zone is etched by chemical materials to form a partitioned optical zone (i.e., a peripheral imaging interference zone is formed in the myopic defocus zone), interfering with the imaging of the human eye and preventing direct vision through this peripheral area. When the eyeball rotates, a clear image cannot be obtained. After judgment by the brain, the mode of gazing at things will be actively adjusted to head rotation, and the glasses and the eyes always maintain the same angle, so that the human eye - lens system can always be in the centered position, achieving myopic peripheral defocus in the orthophoric eye position.

[0044] <Example 2>

[0045] (1) Lens parameters: The peripheral defocus control frame glasses are prepared in the manner of CN106707542B. Its lens is composed of front and back surfaces. The total diameter of the lens is 80 mm, the central thickness is 3 mm, and the refractive index of the material is 1.55. The curvature radius of the front surface of the optical zone is 7.724, the curvature radius of the back surface is 5.954, and the back surface is an aspherical surface. The surface shape expression is:

[0046]

[0047] Among them, c is the reciprocal of the surface curvature radius of the basic spherical surface of the optical part, y is the vertical distance from any point on the curve to the horizontal coordinate axis (Z), Q is the aspherical coefficient, A2i is the aspherical high - order term coefficient, and the aspherical surface is obtained by rotating the aspherical curve symmetrically around the horizontal coordinate axis (Z). The lens parameters are shown in Table 1.

[0048] Table 1 Lens parameters of Example 2

[0049]

[0050] (2) Make a thin - film patch, with a shape like Figure 4As shown in Figure E, the film patch is opaque or translucent, in the shape of an isosceles triangle with a height of 10 mm and a base width of 1 mm. Twenty-six such patches are made and pasted radially outside the optical zone within the range of 10 mm - 20 mm, which serves to block continuous peripheral imaging. However, there are still intermittent areas around that can transmit light, thus imaging the peripheral myopic defocus onto the eye. The film patch can be pasted on the front surface of the lens, or on the back surface of the lens, or distributed on both surfaces.

[0051] After the lens is processed, within 10 mm of the center is still the optically clear imaging zone (i.e., the central optical zone) through which the human eye can view objects normally. The myopic defocus zone around the central optical zone is blocked by the film patch, forming a segmented optical zone (i.e., a peripheral imaging interference zone in the myopic defocus zone). In this way, the human eye is interfered and cannot directly view objects through this peripheral area. When the eyeball rotates, a complete image cannot be obtained. After judgment, the brain will actively adjust the mode of gazing at things to head rotation, keeping the glasses and the eyes at the same angle at all times. Therefore, the human eye - lens system can always be in the centered position, achieving myopic peripheral defocus in the orthophoric eye position.

[0052] In addition to being applicable to the lens structures disclosed in US7025460 and CN106707542B, the technical means of this embodiment can also be applied to other peripheral myopic defocus lenses, such as the lenses disclosed in other patent documents mentioned in the background art. The specific description of their structures is omitted here by citing the document numbers. Therefore, on the premise of no conflict, the lens structures disclosed in these patent documents also belong to the disclosure content of this application.

[0053] Adopting this embodiment can improve the myopia control effect of frame glasses with peripheral defocus structures.

[0054] Specifically, in this embodiment, the peripheral part of the lens with a peripheral myopic defocus design is subjected to regional blurring and segmentation processing. During the process of the brain autonomously selecting the fovea to orient to the most interesting area within the visual field, due to the characteristics of blurred imaging or inability to form an image of sufficient size and continuity in the peripheral part, when the human eye looks around, the peripheral light is interfered. When the eyeball rotates, a clear image cannot be obtained. After judgment, the brain will actively adjust the mode of gazing at things to head rotation, keeping the glasses and the eyes at the same angle at all times, which can keep the human eye - lens system in the centered position all the time, thus solving the problem of unstable defocus state caused by the rotation of the human eye when viewing objects with a peripheral defocus design, forming a more stable myopic peripheral defocus, and obtaining the expected myopia control effect.

[0055] In addition, adopting this embodiment can also achieve technical effects with various forms, easy implementation, and low cost.

[0056] Specifically, the price of the peripheral defocus lens is generally relatively high, while the present embodiment is easy to implement and has low cost, and will not significantly increase the cost of the peripheral defocus lens. In addition, the lenses provided by the present embodiment have various forms and textures, and can be adjusted according to the wearer's economic conditions, implementation conditions, and personal preferences.

[0057] <Second Embodiment>

[0058] This embodiment relates to a method for manufacturing the spectacle lens and the framed glasses in the first embodiment. For the same parts as in the first embodiment, the detailed description thereof is omitted.

[0059] In the manufacturing method of the present embodiment, the following processes are included: a. Obtaining a spectacle lens (original lens) having a peripheral myopic defocus structure; b. Forming a peripheral imaging interference region on the outer periphery of the central optical region of the spectacle lens. Among them, the central optical region is the imaging region corresponding to the pupil, with a diameter of 5 mm to 15 mm, preferably in the range of 5 mm to 10 mm, and plays a role in clear imaging. The imaging interference region is outside the central optical region, with a diameter of 5 to 30 mm, preferably in the range of 10 to 20 mm, and plays a role in interfering with the continuous and clear imaging of the periphery of the lens and preventing the human eye from directly gazing at the image through the peripheral region. The interference region can be patterns, patterns, letters, lines, etc. of different shapes. The patterns in the interference region can be regular or irregular; there are gaps between the interference patterns and they cannot be completely continuous and blocked. The gaps between the interference regions allow peripheral light to pass through and be imaged at positions outside the fovea of the retina to form peripheral defocus. The interference patterns in the interference region can be transparent, opaque, or of different colors. The patterns in the interference region can be achieved by means of film patching, coating, machining, etching, photolithography, writing, printing, etc., and can also be achieved by changing the refractive index, light transmittance, etc. of the lens material in the interference region.

[0060] <Third Embodiment>

[0061] This embodiment relates to a peripheral imaging interference device for glasses, and the peripheral imaging interference device is used in combination with a lens having a peripheral myopic defocus structure. The peripheral imaging interference device can be, for example, a film patch, and patterns as shown in, for example Figure 4 are formed on the film patch. That is, on the film patch, there is a central region and a peripheral region located outside the central region. The central region is transparent, and there are an imaging interference part and transparent gap parts between different parts of the imaging interference part in the peripheral region. Here, "transparent" can be achieved by a transparent material or by opening holes in the film. That is, in the transparent region, there can be a transparent material or there can be no material.

[0062] On the premise of no conflict, the structure and formation method of the imaging interference part here can follow the method described in the first embodiment.

[0063] In addition, the size of the central area of the peripheral imaging interference device can be the same as that of the central optical area in the first embodiment, that is, with a diameter of 5 mm to 15 mm, preferably in the range of 5 mm to 10 mm. The peripheral area is an area with an outer diameter of 5 to 30 mm, preferably 10 to 20 mm, of the central area.

[0064] In addition, in addition to the film patch method, the peripheral imaging interference device can also adopt other methods, such as other sheet materials such as paper and glass sheets or components of other shapes. In addition, for the combination of the peripheral imaging interference device and the spectacle lens, in addition to the pasting method, other connection methods can also be adopted. For example, the peripheral imaging interference device can be provided with a clamping mechanism to clamp the sheet material and the spectacle lens.

[0065] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

[0066] For example, although frame glasses are the preferred application direction of the present invention, the present invention is not limited to being used on frame glasses. For the human eye, if the method of controlling myopia by peripheral defocus is adopted and the human eye cannot ensure synchronization with the lens, the method of the present invention can be used for intervention to improve the myopia control effect. For example, for contact lenses, although most contact lenses can maintain good synchronization with eye movement, contact lenses with a smaller diameter or a larger mobility on the eyeball may have problems similar to those of frame glasses. Therefore, the method of the present invention can also be used in the design of defocus control contact lenses.
