Abstract
Description
Technical Field
[0001] This utility model relates to the field of lens technology, specifically to a dot-diffusion fogging lens, eyeglasses, and contact lenses that inhibit the progression of vision deterioration. Background Technology
[0002] The eye is a sophisticated optical system, composed of the cornea, lens, retina, vitreous humor, and other structures that work together to produce vision. Visual development is influenced by many factors, including living environment, eye habits, diseases, and genes. Myopia (nearsightedness) occurs when the eye's overall refractive power is too strong, causing light rays from distant objects to focus in front of the retina rather than directly on it. Conversely, hyperopia (farsightedness) occurs when the eye's overall refractive power is too weak, causing light rays from distant objects to focus behind the retina rather than directly on it.
[0003] The visual signal-dependent mechanism of refractive development originates within the eye. The main visual signals affecting the intraocular emmetropization process include contrast and optical defocus. Optical defocus affects the emmetropization process by influencing the position of retinal imaging, while contrast can also adjust the overall image contrast to affect the emmetropization process. The emmetropization process is the process of myopia control. In other words, in addition to optical defocus, the general factors causing myopia also include the contrast of image formation.
[0004] Existing ground glass lenses suppress myopia progression by reducing the contrast of image formation. These lenses typically consist of a central corrective zone and a ground glass zone, with the ground glass zone located outside the central corrective zone. By reducing contrast, they control myopia. However, existing ground glass lenses lack a diffusion point within the central corrective zone for intervention, resulting in a significant contrast difference between the central corrective zone and the outer ground glass zone. This high contrast difference not only affects the myopia progression suppression effect but also makes the lenses uncomfortable to wear and difficult to adapt to. Utility Model Content
[0005] The purpose of this utility model is to provide a dot-diffusion fogging lens that inhibits the slow progression of vision deterioration, thereby solving the aforementioned technical problems in the prior art; the preferred technical solutions among the various technical solutions provided by this utility model can produce a variety of technical effects, as detailed below.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] This utility model provides a dot-diffuse fogging lens that inhibits vision deterioration and slows down the progression of vision impairment. The lens body includes an optical correction area and a dot-blocking diffuse scattering fogging area. The optical correction area is located in the center of the lens body, and the dot-blocking diffuse scattering fogging area surrounds the optical correction area. Multiple unit fogging portions are densely distributed within the dot-blocking diffuse scattering fogging area. A transition fogging area is provided within the optical correction area, and multiple transition fogging portions are discretely arranged within the transition fogging area. The density of the transition fogging portions relative to the optical correction area is less than the density of the unit fogging portions relative to the dot-blocking diffuse scattering fogging area.
[0008] Preferably, multiple transition fog and sand zones are sequentially arranged in the transition fog and sand zone from the inside to the outside; the transition fog and sand zone includes multiple transition fog and sand sections evenly arranged in the circumferential direction.
[0009] Preferably, the number of transitional fog and sand sections included in the transitional fog and sand zone increases gradually from the inside to the outside.
[0010] Preferably, along the direction from the inside to the outside, the diameter of the transition fog sand section of the transition fog sand zone gradually increases; the diameter of the transition fog sand section is not greater than the diameter of the unit fog sand section.
[0011] Preferably, a plurality of peripheral fog and sand zones are sequentially arranged in the direction from the inside to the outside within the point-blocking diffuse fog and sand zone; the peripheral fog and sand zone includes a plurality of unit fog and sand sections evenly arranged in the circumferential direction; the shape of the peripheral fog and sand zone is adapted to the shape of the transition fog and sand zone; the number of unit fog and sand sections included in the innermost peripheral fog and sand zone is greater than the number of transition fog and sand sections included in the outermost transition fog and sand zone.
[0012] Preferably, the transition fog and sand belt and the outer fog and sand belt are circular or hexagonal in shape.
[0013] Preferably, satellite points are also provided within the point-blocking diffuse scattering fog and sand area, and satellite points are correspondingly provided around the periphery of each unit fog and sand section; the diameter of the satellite points is smaller than the diameter of the unit fog and sand section.
[0014] Preferably, the peripheral fog and sand belt includes satellite points uniformly arranged circumferentially, with the satellite points and unit fog and sand sections on the same peripheral fog and sand belt arranged alternately in sequence.
[0015] Preferably, a defocus area is provided within the point-blocking diffuse scattering fog and sand area; the defocus area includes multiple defocus zones arranged sequentially from the inside to the outside; the defocus zones include multiple defocus portions evenly distributed circumferentially.
[0016] Preferably, a fine and soft area is provided at the center of the optical correction area, and a transitional fogging area is arranged around the outside of the fine and soft area. Multiple central fogging portions are densely distributed within the fine and soft area. The diameter of the central fogging portions is smaller than the diameter of the transitional fogging portions, and the density of the central fogging portions relative to the fine and soft area is greater than the density of the transitional fogging portions relative to the transitional fogging area.
[0017] Preferably, the lens body is configured as a concave lens, and the unit fog section and the transition fog section are configured as grooves or protrusions.
[0018] Preferably, the lens body is configured as a convex lens, and the unit fog section and the transition fog section are configured as grooves or protrusions.
[0019] This invention provides eyeglasses, including any of the aforementioned dot-diffusion fogging lenses that inhibit vision from worsening.
[0020] This invention provides a contact lens, including any of the aforementioned dot-diffusion fogging lenses that inhibit vision from worsening.
[0021] The dot-diffusion fogging lens, eyeglasses, and contact lenses provided by this utility model have at least the following beneficial effects:
[0022] The dot-diffusion fogging lens that inhibits vision progression includes a lens body with an optical correction area and a dot-block diffuse scattering fogging area. The optical correction area is used for vision correction, and the dot-block diffuse scattering fogging area balances contrast through scattering to inhibit vision progression.
[0023] The optical correction zone is located in the center of the lens body, and the dot-block diffuse scattering haze zone is arranged around the outer side of the optical correction zone. The dot-block diffuse scattering haze zone contains multiple densely packed unit haze portions. A transition haze zone is provided within the optical correction zone, and multiple discrete transition haze portions are discretely arranged within the transition haze zone. The density of the discrete transition haze portions is less than the density of the densely packed unit haze portions. This creates a gradual transition area between the optical correction zone and the dot-block diffuse scattering haze zone, effectively balancing the visual acuity increase caused by high contrast, resulting in significant visual acuity correction and suppression of further visual acuity increase. Furthermore, it does not sacrifice visual experience, providing both uniform visual perception and balanced contrast. At the same time, the point-blocking diffuse scattering effect allows light of different wavelengths to collide, transforming glaring light into soft light. The point-blocking diffuse scattering effect can also block some ultraviolet rays from damaging the lens, reducing the occurrence of cataracts. It can also block some blue light from damaging the macula of the retina, reducing the occurrence of macular degeneration. It is also widely applicable to people who use electronic products at night with the lights off, balancing the damage to the eyes caused by high contrast. The point-blocking diffuse scattering effect reduces the burden on the eyes when the lens has a slightly foggy perception, while maintaining a clear field of vision.
[0024] This invention, by setting discrete transition fogging sections within the optical correction zone, enables the formation of a gradual, transitional diffuse fogging zone between the optical correction zone and the dot-block diffuse fogging zone. This comprehensively interferes with and balances the contrast. For myopia lenses, this effectively suppresses the progression of myopia while providing a uniform visual experience, balanced contrast, clear vision, and greater wearing comfort.

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0044] Example 1:
[0045] This invention provides a dot-diffusion fogging lens that inhibits the progression of vision deterioration. (Reference) Figures 1 to 3 As shown, the dot-diffusion fogging lens that inhibits vision from worsening includes a lens body 1, on which an optical correction area 2 and a dot-blocking diffuse scattering fogging area 3 are provided.
[0046] The optical correction area 2 is located in the middle of the lens body 1, and the dot-block diffuse scattering fog area 3 is arranged around the outside of the optical correction area 2. The dot-block diffuse scattering fog area 3 is densely covered with multiple unit fog parts 311.
[0047] An optical correction area 2 is provided with a transition fog area 21, and multiple transition fog sections 211 are discretely provided in the transition fog area 21. The density of the transition fog section 211 relative to the transition fog area 21 is less than the density of the unit fog section 311 relative to the point-block diffuse scattering fog area 3.
[0048] The lens body 1 is configured as a concave lens, and the unit fog section 311 and the transition fog section 211 are both configured as grooves or protrusions, preferably C-shaped protrusions; the dot diffusion fogging lens that inhibits the slowing down of vision progression is a myopia lens.
[0049] When in use, the user wears the dot-diffusion fogging lens that inhibits vision from worsening. After some light is refracted by the optical correction zone 2, it is focused onto the retina.
[0050] Another portion of the light enters the point-blocked diffuse scattering fog zone 3. Under the scattering effect of the unit fog section 311, the imaging contrast is weakened, thereby inhibiting the further progression of myopia.
[0051] In the aforementioned process, since the optical correction area 2 has multiple discrete transition fog sections 211, a gradual and transitional diffuse fog area is formed between it and the dot-block diffuse fog area 3. When light passes through, it can effectively buffer the contrast difference between the optical correction area 2 and the dot-block diffuse fog area 3. This not only significantly inhibits and delays the progression of myopia, but also makes the contrast transition between the optical correction area 2 and the dot-block diffuse fog area 3 more delicate and natural, ensuring a clear vision while making the wearer more comfortable.
[0052] Example 2:
[0053] Example 2 is based on Example 1:
[0054] like Figures 1 to 3 As shown, multiple transition fog and sand zones are arranged sequentially from the inside to the outside within the transition fog and sand zone 21. Each transition fog and sand zone includes multiple transition fog and sand sections 211 that are uniformly arranged circumferentially.
[0055] The diffuse scattering transition fog zone, which is composed of multiple transition fog zones, has a more regular and uniform distribution of transition fog section 211.
[0056] As an optional implementation, the number of transition fog sections 211 included in the transition fog zone gradually increases from the inside to the outside. In this way, the transition fog sections 211 are first sparse and then dense from the inside to the outside, making the transition between the optical correction area 2 and the point-block diffuse scattering fog area 3 more natural.
[0057] As an optional implementation, the diameter of the transition fog sand section 211 of the transition fog sand zone gradually increases from the inside to the outside; the diameter of the transition fog sand section 211 is not greater than the diameter of the unit fog sand section 311.
[0058] By combining the method of gradually increasing the quantity from the inside out with the method of gradually increasing the diameter from the inside out, a multi-gradient diffuse scattering transition fog and sand zone can be formed, with a significant gradual transition effect. While ensuring the effect of inhibiting the deepening of vision, it further improves the wearing comfort.
[0059] As an optional implementation, a plurality of peripheral fog and sand bands 31 are arranged sequentially from the inside to the outside within the point-blocking diffuse fog and sand area 3. The peripheral fog and sand bands 31 include a plurality of unit fog and sand parts 311 evenly arranged in the circumferential direction, and the shape of the peripheral fog and sand bands 31 is adapted to the shape of the transition fog and sand bands.
[0060] refer to Figures 1 to 3 As shown, the transition fog and sand belt and the outer fog and sand belt 31 are configured as regular hexagons.
[0061] Alternatively, refer to Figures 4 to 6 As shown, the transition fog and sand belt and the outer fog and sand belt 31 are circular in shape.
[0062] As an optional implementation, the number of unit fog sand sections 311 included in the innermost peripheral fog sand zone 31 is greater than the number of transition fog sand sections 211 included in the outermost transition fog sand zone.
[0063] As an optional implementation, the dot-diffuse fogging lens that inhibits the slowing of vision progression is set as a full-coverage lens, in which the dot-block diffuse fogging area 3 covers the entire lens body 1 except for the optical correction area 2, thereby balancing the overall contrast of the lens.
[0064] In practical applications, the spacing between adjacent transition fog zones, the spacing between adjacent transition fog sections 211, the size and number of transition fog sections 211, the spacing between adjacent peripheral fog zones 31, the spacing between adjacent unit fog sections 311, the size and number of unit fog sections 311, the diameter of the optical correction area 2, and the diameter of the dot-block diffuse scattering fog area 3 can be customized according to individual needs, based on differences in each person's visual sensitivity.
[0065] Optionally, the diameter of the unit mist section 311 is set to 0.1 to 0.35 mm, and the spacing between two adjacent unit mist sections 311 is set to 0.08 to 0.39 mm.
[0066] The diameter of the transition fog sand section 211 is set to 0.03 to 0.28 mm, and the distance between two adjacent transition fog sand sections 211 is set to 0.06 to 0.5 mm.
[0067] The table below shows the refraction results of 70 adolescents aged 7 to 17 with good visual function after wearing the aforementioned dot diffusion fogging lenses that inhibit vision progression and delay the worsening of vision for about one year.

[0077]
[0078] In the table above, numbers 1 to 70 are codes for teenagers aged 7 to 17.
[0079] In the table, left represents the left eye, right represents the right eye, S represents myopia power, C represents astigmatism power, and A represents astigmatic axis angle. For example, right S-2.25C-0.50A178 specifically means that the refraction result of the right eye is myopia of 225 degrees, astigmatism of 50 degrees, and astigmatic axis angle of 178°.
[0080] As shown in the table above, among the 70 teenagers, only those numbered 9, 10, 20, 29, 30, 39, 40, 49, and 50 experienced an increase in vision, accounting for approximately 13%. The increase in degree generally did not exceed 25 degrees. Notably, number 30 experienced a 25-degree increase in vision after about six months, but its vision returned to the level it was at when glasses were prescribed after one year. Furthermore, numbers 3, 4, 13, 23, 33, 43, and numbers 51-60 experienced a decrease in myopia, accounting for approximately 23%, indicating a slowdown in the rate of myopia progression. As mentioned above, 87% of the 70 users did not experience a further increase in myopia after one year, with 23% even experiencing a reduction in myopia degree. Therefore, this invention has a significant effect in inhibiting the progression of myopia.
[0081] Example 3
[0082] The difference between Example 3 and Example 2 is that:
[0083] like Figure 7 and Figure 8 As shown, a fine and soft area 22 is provided at the center of the optical correction area 2, and a transition fog area 21 is arranged around the outside of the fine and soft area 22. Multiple central fog parts 221 are densely distributed in the fine and soft area 22. The central fog parts 221, the transition fog parts 211 and the unit fog parts 311 have similar structures and are set as protrusions or grooves.
[0084] The diameter of the central fog section 221 is smaller than the diameter of the transition fog section 211. Specifically, the diameter of the central fog section 221 is less than 1 / 5 of the diameter of the unit fog section 311 of the point-blocking diffuse fog region 3.
[0085] The density of the central fog sand section 221 relative to the fine and soft zone 22 is greater than the density of the transition fog sand section 211 relative to the transition fog sand zone 21.
[0086] As an optional implementation, the central fog sand section 221, the transition fog sand section 211, and the unit fog sand section 311 are irregularly distributed.
[0087] Optionally, the diameter of the central mist section 221 is set to 0.01 to 0.2 mm, and the distance between two adjacent central mist sections 221 is set to 0.1 to 0.5 mm.
[0088] The central part of the optical correction area 2 is fully covered by the delicate and soft area 22, which can effectively balance the visual contrast of the dot-block diffuse haze area 3 and the transition haze area 21. It can reduce the density and depth of the dot-block diffuse haze area 3, improve the overall clarity of the lens, reduce the haze value, reduce the rainbow pattern and halo phenomenon caused by night lights, and reduce visual impairment.
[0089] In the production process of the dot-diffusion hazy lens that inhibits vision from worsening, the lens body 1 is formed by injection molding and resin curing, or by machining and polishing a semi-finished substrate. Then, the lens body 1 is hardened, and the hazy part is processed by high-density laser processing to give it a good hazy feel. Finally, a coating is applied to complete the lens production.
[0090] Compared to existing lenses that are directly laser-treated on the coating layer, this production method can reduce the visual obstruction caused by the dispersive rainbow halo after the lens frosting process. At the same time, it can reduce the defects caused by the delamination of the coating layer and the easy accumulation of dirt in the grooves between the convex points after laser treatment caused by direct laser laser treatment. It can significantly improve the lens's anti-fouling ability and enhance the overall optical performance and aesthetics of the lens.
[0091] Example 4
[0092] Example 4 is based on Example 2:
[0093] like Figure 9 and Figure 10 As shown, satellite points 312 are also provided in the diffuse scattering fog and sand area 3. Each unit fog and sand section 311 is surrounded by 1 to 3 satellite points 312. The satellite points 312 are evenly or irregularly distributed relative to their corresponding unit fog and sand section 311. The satellite points 312 are set as protrusions or grooves, and their diameter is smaller than the diameter of the unit fog and sand section 311. The diameter of the satellite points 312 is between 0.01 and 0.13 mm.
[0094] The setting of satellite point 312 can further balance the fog effect and contrast. To a certain extent, it can reduce the number of unit fog sections 311 and increase the spacing between unit fog sections 311, thereby enhancing the overall clarity of the lens. It also has the functions of reducing visual obstruction, reducing rainbow patterns, halos and light spots caused by night lights, and ensuring a clear field of vision.
[0095] Example 5
[0096] Example 5 is based on Example 2:
[0097] like Figure 11 and Figure 12 As shown, the outer fog and sand belt 31 includes satellite points 312 evenly arranged along the circumference. The satellite points 312 and unit fog and sand sections 311 on the same outer fog and sand belt 31 are arranged alternately in sequence, that is, satellite points 312 are arranged between two adjacent unit fog and sand sections 311.
[0098] The structure of satellite point 312 is the same as that of unit fog and sand section 311, but the diameter of satellite point 312 is smaller than the diameter of unit fog and sand section 311.
[0099] This setup, with its evenly and regularly distributed satellite points 312, makes the contrast difference buffering effect more significant.
[0100] Optionally, the diameter of the satellite point 312 is set to 0.046 mm, the diameter of the unit fog sand section 311 is set to 0.165 mm, the distance between two adjacent satellite points 312 is 0.339 mm, and the distance between two adjacent unit fog sand sections 311 is 0.230 mm.
[0101] Example 6
[0102] Example 6 is based on Example 4:
[0103] like Figures 13 to 15 As shown, a defocused area 4 is set within the point-blocked diffuse scattering fog and sand area 3.
[0104] The defocus area 4 includes a plurality of defocus zones 41 arranged sequentially from the inside to the outside. Each defocus zone 41 includes a plurality of defocus portions 411 evenly distributed in the circumferential direction. Each defocus portion 411 is configured as a protrusion.
[0105] Along the direction from the inside out, the number of defocused portions 411 included in the defocused band 41 increases gradually. Optionally, the number of defocused bands 41 is 8. Along the direction from the inside out, the number of defocused portions 411 in the defocused band 41 is 72, 79, 86, 93, 100, 107, 114 and 122 respectively. The diameter of the defocused portion 411 is 1.15mm.
[0106] The setting of defocus zone 4 ensures that when light is refracted, it is focused in front of the retina through the pupil, resulting in an image that is ahead of the retina and forms a myopic defocus, which effectively inhibits the progression of myopia.
[0107] Example 6 combines the defocus principle and the contrast principle, resulting in a more significant effect in inhibiting the progression of vision problems.
[0108] Example 7
[0109] The difference between Example 7 and Example 2 is that:
[0110] The lens body 1 is configured as a convex lens, and the unit fogging part 311 and the transition fogging part 211 are configured as grooves or protrusions. This embodiment is mainly for farsighted children who are about to develop myopia and whose farsighted reserve is close to the critical point.
[0111] Example 8
[0112] Example 8 is based on any of the foregoing examples:
[0113] This invention provides a pair of eyeglasses, which include any of the aforementioned dot-diffusion fogging lenses that inhibit vision from worsening.
[0114] The glasses using the aforementioned dot-diffusion fogging lens that inhibits the slowing down of vision progression not only have good vision correction and vision progression inhibition effects, but also provide a good visual experience by improving the contrast between the diffuse scattering transition fogging area 2 and the dot-block diffuse scattering fogging area 3. While ensuring a clear vision, they have a more balanced contrast, which can effectively ensure the wearer's compliance and comfort.
[0115] Example 9
[0116] This utility model provides a contact lens, which includes any of the aforementioned dot-diffusion fogging lenses that inhibit vision from worsening and delays its progression, wherein the lens body 1 is made of existing contact lens materials.
