Description

Technical Field

[0001] This utility model relates to the technical field of eyeglasses, and more specifically, to a composite multi-microlens type defocusing lens and a functional eyeglass frame. Background Technology

[0002] Myopia has become a global public health problem, showing a trend of affecting younger people and becoming more prevalent, causing numerous inconveniences to people's lives, studies, and work. Therefore, myopia prevention and control is of paramount importance. Currently, there are various lens products on the market for myopia control, among which defocus lenses are a relatively common type.

[0003] Traditional defocus lenses aim to slow myopia progression by creating a defocused state in a specific area of ​​the lens. However, most existing defocus lenses use microlenses with a single defocus amount, and the retina easily adapts to this single defocus stimulus. With prolonged use, retinal sensitivity decreases, leading to a gradual decline in the defocus effect and making it difficult to maintain myopia control.

[0004] Based on this, we provide a composite multi-microlens defocusing lens and a functional frame. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a composite multi-microlens type defocus lens and a functional frame. By changing the amount and spatial distribution of defocus, it breaks the retinal adaptability, generates non-uniform defocus stimulation, prolongs the duration of myopia control effect, and delays the decay of defocus effect caused by long-term single stimulation.

[0006] The present invention provides a composite multi-microlens type defocusing lens and a functional eyeglass frame, which adopts the following technical solution:

[0007] A composite multi-microlens defocusing lens includes a distance vision region in the central region of the lens; a near vision region in the lower region of the lens; and a lens disposed between the lens and the distance vision region, the lens comprising multiple lens groups; the lens group comprising a macrolens, a medium lens, and a microlens, wherein the power of the macrolens, the medium lens, and the microlens are all different.

[0008] Preferably, the lens has a diopter of +2.00 to +5.00D, is arranged in a ring shape, and the ring spacing is 1-2mm.

[0009] A functional eyeglass frame includes a composite multi-microlens type defocusing lens and a frame; the frame is made of far-infrared emitting material, and the frame can emit far-infrared light towards the side of the frame closest to the temple.

[0010] In summary, this utility model has the following beneficial technical effects:

[0011] 1. By setting a lens group on the lens, and the large lens, medium lens and small lens in the lens group are all of different diopters, this design can form different defocus amounts in the same area on the retina. When the external scene is imaged on the retina through the lens, its imaging focal point is different. By changing the defocus amount and spatial distribution, the retinal adaptability is broken, non-uniform defocus stimulation is generated, the duration of myopia control effect is extended, and the defocus effect decay caused by long-term single stimulation is delayed.

[0012] 2. By setting a near-vision zone, traditional defocus lenses, when used for writing, cause the eyes to look downwards. This, combined with the defocus microlens, affects visual image quality, leading many children to tilt their heads down, which can cause long-term neck strain. Setting a near-vision zone improves visual comfort when looking downwards while reading and writing. Furthermore, adding positive lenses and / or prisms to the near-vision zone reduces accommodative lag by decreasing ciliary muscle contraction, alleviating retinal defocus shift caused by insufficient accommodation during near work, reducing hyperopic defocus in the macula, and complementing peripheral defocus signals. Secondly, the synergistic effect of the positive lenses and microlenses in the near-vision zone creates "central correction + peripheral myopic defocus," specifically: central zone: corrects refractive errors in the dominant visual area; peripheral microlenses: form an anterior retinal defocus zone, inhibiting axial elongation. This achieves dynamic adaptive defocus distribution, ensuring continuous coverage of the target retinal area by the near-vision defocus signal when the eye moves downwards, thanks to the distribution of microlenses in conjunction with positive lenses. Furthermore, by adding a prism in the near vision zone, the burden of convergence can be reduced, inward eye movement can be decreased, and pressure on the eyeball from the extraocular muscles can be lessened, making eye use easier and thus alleviating eye strain caused by near work. Through the composite design of a positive lens / prism and microlens in the near vision zone, a three-dimensional synergy is achieved, reducing accommodative lag, compensating for convergence, and enhancing defocus signals. This overcomes the limitations of traditional defocus lenses in dynamic eye use scenarios, providing a more precise solution for myopia prevention and control in adolescents, and facilitating better myopia control. This defocus microlens area is formed by two central zones, each composed of a large, medium, and small lens, arranged in a gourd shape, one above the other. Multiple defocus microlens groups are arranged in a multi-layered ring array around the center of the upper central zone, with equal spacing between each ring. One ring array overlaps with the lens group at the bottom of the lower central zone. The upper central zone (one of the central zones) is the distance vision zone, and the lower central zone (the other) is the near vision zone. This arrangement effectively slows down the progression of myopia. The multi-microlens defocus lens, through its microlens layout, creates myopic defocus in front of the retina, thus inhibiting abnormal axial elongation. For adolescents with myopia, this defocus design effectively slows the rate of myopia progression, providing a more effective means of controlling myopia development. Simultaneously, the clear visual range is expanded, and the rational layout of the defocus microlens area ensures clear vision in different areas of the lens. Different microlens arrangements are set in the central and peripheral areas, which not only ensures clear central vision but also expands the range of clear vision and reduces visual distortion. The shape and spacing of the microlenses are carefully designed so that, compared with traditional lenses, the wearer can get a more natural and comfortable visual experience when looking at objects, and reduce discomfort symptoms such as dizziness and eye fatigue.

[0013] 3. The frames are made of far-infrared emitting materials, and the frames can emit far-infrared light towards the side closest to the temples, which promotes vasodilation, improves blood supply to the user's eyes, and is beneficial for myopia control.

[0021] Example 1

[0022] This utility model discloses a composite multi-microlens type defocusing lens. (Refer to...) Figures 1 to 2 As shown, a composite multi-microlens defocusing lens includes a lens 1, with a distance vision area 2 (8.5 mm in diameter) in the central region of the lens 1; a near vision area 3 is provided in the lower region of the lens 1; a lens is provided between the lens 1 and the distance vision area 2, and the lens includes multiple lens groups 4; the lens group 4 includes a large lens 400, a medium lens 401 and a small lens 402, and the power of the large lens 400, the medium lens 401 and the small lens 402 are all different, and the lenses are distributed in a gourd shape and arranged according to a certain rule.

[0023] Specifically, by setting lens group 4 on lens 1, and the large lens 400, medium lens 401 and small lens 402 in lens group 4 all have different diopters, this design can form different defocus amounts in the same area on the retina. When external objects are imaged on the retina through lens 1, their imaging focal points are different. Through the changes in defocus amount and spatial distribution, the retinal adaptability is broken, non-uniform defocus stimulation is generated, the duration of myopia control effect is extended, and the defocus effect decay caused by long-term single stimulation is delayed. The frame made of far-infrared emitting material can generate far-infrared rays to irradiate the acupoints around the eye socket and the area near the temple, improve the blood supply to the choroid, and facilitate myopia control.

[0024] Specifically, the refractive power of the lenses ranges from +2.00 to +5.00D, forming a ring-shaped distribution with a ring spacing of 1-2mm.

[0025] Specifically, lens 1 can be designed as round or rectangular.

[0026] Specifically, the diopter of the large lens 400, the medium lens 401, and the small lens 402 are 3.00D, 3.50D, and 4.50D, respectively, and their diameters are 1.2mm, 1.1mm, and 1.0mm, respectively. The ring spacing between the lens groups 4 is 1.0mm.

[0027] It is worth noting that the large lens 400 in lens group 4 is 3.00D. Starting from the center area, the defocus increases by 0.30D with each ring, that is, the first ring is 3.00D, the second ring is 3.30D, the third ring is 3.60D, the fourth ring is 3.90D, and so on. This defocus design, which increases the defocus amount at the periphery, also allows the microlenses with different defocus amounts to form a dynamic defocus signal on the retina after external light passes through the eye.

[0028] Specifically, by setting a near-vision zone, traditional defocus lenses, when used for writing, cause the eyes to look downwards. This, combined with the defocus microlens, affects visual image quality, leading many children to look down and causing long-term neck strain. Setting a near-vision zone improves visual comfort when looking downwards while reading and writing. Furthermore, adding positive lenses and / or prisms to the near-vision zone reduces accommodative lag by decreasing ciliary muscle contraction, alleviating retinal defocus shift caused by insufficient accommodation during near work, reducing hyperopic defocus in the macula, and complementing peripheral defocus signals. Secondly, the synergistic effect of the positive lens and microlens in the near-vision zone creates "central correction + peripheral myopic defocus," namely: central zone: corrects refractive errors in the dominant visual area; peripheral microlenses: form an anterior retinal defocus zone, inhibiting axial elongation. This achieves dynamic adaptive defocus distribution, ensuring continuous coverage of the target retinal area by the near-vision defocus signal when the eye moves downwards, through the distribution of microlenses in conjunction with the positive lens. Furthermore, by adding a prism in the near vision zone, the burden of convergence can be reduced, inward eye movement can be decreased, and pressure on the eyeball from the extraocular muscles can be lessened, making eye use easier and thus alleviating eye strain caused by near work. Through the composite design of a positive lens / prism and microlens in the near vision zone, a three-dimensional synergy is achieved, reducing accommodative lag, compensating for convergence, and enhancing defocus signals. This overcomes the limitations of traditional defocus lenses in dynamic eye use scenarios, providing a more precise solution for myopia prevention and control in adolescents, and facilitating better myopia control. This defocus microlens area is formed by two central zones, each composed of a large, medium, and small lens, arranged in a gourd shape, one above the other. Multiple defocus microlens groups are arranged in a multi-layered ring array around the center of the upper central zone, with equal spacing between each ring. One ring array overlaps with the lens group at the bottom of the lower central zone. The upper central zone (one of the central zones) is the distance vision zone, and the lower central zone (the other) is the near vision zone. This arrangement effectively slows down the progression of myopia. The multi-microlens defocus lens, through its microlens layout, creates myopic defocus in front of the retina, thus inhibiting abnormal axial elongation. For adolescents with myopia, this defocus design effectively slows the rate of myopia progression, providing a more effective means of controlling myopia development. Simultaneously, the clear visual range is expanded, and the rational layout of the defocus microlens area ensures clear vision in different areas of the lens. Different microlens arrangements are set in the central and peripheral areas, which not only ensures clear central vision but also expands the range of clear vision and reduces visual distortion. The shape and spacing of the microlenses are carefully designed so that, compared with traditional lenses, the wearer can get a more natural and comfortable visual experience when looking at objects, and reduce discomfort symptoms such as dizziness and eye fatigue.

[0029] Example 2

[0030] This utility model discloses a functional eyeglass frame. (Refer to...) Figure 3 As shown, a functional eyeglass frame includes a compound multi-microlens type defocusing lens and a frame 7;

[0031] The frame 7 is made of far-infrared emitting materials, and the frame of the frame 7 can emit far-infrared light to the side near the temple. The far-infrared emitting materials include far-infrared ceramics (zirconia (ZrO2), alumina (Al2O3), silicon carbide (SiC), etc.), biomass graphene, germanium-based materials (metallic germanium powder, germanium oxide (GeO2)), metal oxides (coated titanium oxide (TiO2), zinc oxide (ZnO)), carbon fiber and its composite materials, tourmaline, nano metal oxides and nano dispersions.

[0032] Biomass graphene emits far-infrared rays with wavelengths of 6-14 micrometers, which highly matches the far-infrared band (3-15 micrometers) emitted by the human body itself. It can penetrate subcutaneous tissue 3-5 centimeters, improving microcirculation and promoting capillary dilation around the eyes. In particular, its peak wavelength of 9.34 micrometers is highly consistent with the peak thermal radiation of the human body (at 37°C). This resonance effect enhances energy transfer efficiency, promotes cell repair and blood circulation, making it suitable for medical applications. It is easily absorbed and generates a resonance effect. Its normal emissivity can reach 93%. Biomass graphene emits far-infrared rays through molecular vibration at room temperature, without relying on electrical energy or heat sources for activation. For example, biomass graphene heating films can work stably at 30°C, making them suitable for patch-type medical devices (such as protective gear and therapeutic patches) or implantable materials. Furthermore, graphene is chemically stable, with high oxidation resistance and mechanical strength. In medical textiles (such as protective gear and mattresses), its far-infrared function can be maintained for several years, retaining more than 80% of its performance after 50 washes. Meanwhile, its porous structure can disrupt bacterial cell walls, achieving an antibacterial rate of over 90%. Furthermore, the material itself poses no radioactive risk and meets medical standards. It can be incorporated into frame materials (such as cellulose acetate or epoxy resin) through masterbatch addition or fiber composite technology to create lightweight, washable temples or frames.

[0033] Far-infrared ceramics, which are ceramic materials containing various metal oxides (such as zirconium oxide and aluminum oxide), emit far-infrared rays when heated, with wavelengths concentrated in the range of 4-14 micrometers and exhibiting high emissivity. They require heating to a certain temperature (usually above 150℃) to effectively emit far-infrared rays, and their energy output is related to the heating time. They can be used for extended periods but rely on an external heat source.

[0034] There are also carbon fibers and their composites. When an electric current is applied, the carbon molecules generate heat through Brownian motion and emit far-infrared rays with a wide wavelength range (3-15 micrometers) and high radiation efficiency. They require a continuous power supply to maintain far-infrared emission, and the material itself can have a lifespan of several decades, but this requires stable circuitry.

[0035] Finally, nano-metal oxides and nano-dispersions, such as nano-sized zinc oxide and titanium oxide, are dispersed to form aqueous or oil-based solutions with a normal emissivity of up to 93%. When these dispersions or masterbatches are added to a substrate, the far-infrared performance is consistent with the substrate's lifespan (e.g., textiles retain over 80% of their functionality after 50 washes). Furthermore, the combination of nano-metal oxides (such as ZnO, Fe2, and O3) with graphene can enhance the material's thermal conductivity and stability; some oxides themselves may possess photocatalytic or antibacterial properties. Simultaneously, the three-dimensional graphene-supported metal oxide micro / nano structures (approximately 500 nm in diameter) combine flexibility and high specific surface area, potentially improving far-infrared radiation efficiency. Nano-metal oxides also exhibit high temperature and corrosion resistance, making them suitable for long-term use in extreme environments. Their combination with graphene can optimize conductivity and mechanical strength; for example, the lightweight design of β-Ti alloy eyeglass frames can draw inspiration from this composite approach.

[0036] Specifically, the frames are made of far-infrared emitting materials, and the frames can emit far-infrared light towards the side closest to the temples, promoting vasodilation, improving blood supply to the user's eyes, and helping to control myopia.
