Description

Technical Field

[0001] This utility model relates to the field of lens technology, and in particular to a gradient dynamic defocus nanolithography fusion multi-point lens and eyeglasses with such a lens. Background Technology

[0002] With the continuous advancement of science and technology, optical technology is being applied more and more widely in various fields, especially in micro-nano manufacturing and vision correction. In recent years, the combination of gradient dynamic defocus nanolithography technology and multi-point defocus lenses has become a research hotspot that has attracted much attention.

[0003] Gradient dynamic defocus nanolithography is an advanced micro / nano fabrication process that achieves fine processing of material surfaces by precisely controlling the defocusing degree of a light beam. This technology enables complex patterning at the nanoscale, featuring high resolution, high precision, and high flexibility. Compared to traditional lithography techniques, gradient dynamic defocus nanolithography is better suited to the needs of different materials and structures, providing new possibilities for the fabrication of micro / nano devices.

[0004] Currently, astigmatism occurs at the point where the edge of a traditional multi-point microlens meets the circular contact point of the lens due to its second-order non-differentiability. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a gradient dynamic defocus nanolithography fusion multi-point lens and eyeglasses with such a lens.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design of a gradient dynamic defocus nanolithography fusion multi-point lens and eyeglasses with such a lens, including a base layer, wherein a plurality of microlenses 1 and microlenses 2 are distributed on the surface of the base layer, the plurality of microlenses 1 having the same specifications and being equidistantly distributed in a ring along the center of the base layer, and having four layers arranged from the inside out, the diameter of the central area spacing of the microlenses 1 being 7.5 mm.

[0008] Several microlenses II are arranged in a ring at equal intervals along the central area of ​​the substrate and diffuse outwards. The diameter of the microlenses II distributed in the same column increases sequentially from the inside to the outside, and the length of the increase is 0.05 mm. The diameter of the defocus area formed by several microlenses I and microlenses II is 45.8 mm. The defocus amount of microlenses I and microlenses II is +3.00D to +6.00D.

[0009] The outer ring wall of the base layer has several mounting grooves distributed thereon, and the mounting grooves are equidistantly distributed along the ring of the base layer.

[0010] This solution utilizes gradient dynamic defocus nanolithography to precisely distribute microlenses 1 and 2 on the substrate surface, forming a multi-layered annular defocus structure. The microlenses 1 are of identical specifications, arranged in four concentric circles with a center-to-center spacing of 7.5 mm to ensure uniformity of defocus. The microlenses 2 adopt an increasing diameter design (each layer increases by 0.05 mm), diffused from the inside out to form a gradient defocus effect. This combined structure can generate dynamic defocus signals in front of the retina, stimulating inhibition of axial elongation, thereby preventing and controlling myopia.

[0011] Meanwhile, the lens divides the imaging astigmatism zone outside the defocus area into micron-sized equilateral blocks. Because these blocks are smaller than the recognition threshold of retinal photoreceptor cells (0 to 50 nanometers), they cannot be perceived and imaged, thus avoiding image jump and visual interference. By eliminating second-order non-differentiable abrupt changes at the optical level (such as the step defocus boundary of traditional lenses), the lens significantly reduces astigmatism interference, achieving dual-effect synergistic control of spherical lenses (myopia correction) and cylindrical lenses (astigmatism correction). In addition, the diameter of the defocus area is strictly controlled at 45.8 mm, covering the main field of view of the human eye, ensuring the overall control effect.

[0012] In detail, the surface of the base layer sequentially includes a polarizing layer, an infrared blocking layer, a hardening layer, an anti-glare layer, and an antistatic layer. The polarizing layer is fixed to the surface of the base layer by adhesive resin. An infrared blocking layer is coated on the other side of the polarizing layer. A hardening layer is bonded to the other side of the infrared blocking layer by adhesive resin. An anti-glare layer is coated on the other side of the hardening layer. An antistatic layer is coated on the other side of the anti-glare layer.

[0013] In detail, the polarizing layer is made of polyvinyl alcohol.

[0014] In detail, the infrared blocking layer is made of niobium oxide.

[0015] In detail, the hardening layer is made of silicon dioxide material.

[0016] In detail, the anti-glare layer is made of titanium dioxide.

[0017] In detail, the antistatic layer is made of carbon nanotube coating material.

[0018] The design scheme proposed in this utility model has the following beneficial effects in application:

[0019] 1. This solution uses gradient dynamic defocus nanolithography to divide the defocus area into micron-level blocks that the retina cannot recognize, effectively eliminating astigmatic interference caused by optical second-order non-differentiability. The annular gradient distribution of microlens one and microlens two can precisely control the amount of defocus, achieving dual control of spherical and cylindrical lenses, significantly improving the myopia control effect. At the same time, the defocus area has a diameter of 45.8 mm, covering a wide range. Combined with nanoscale imaging astigmatic band segmentation technology, it avoids image jump and visual fatigue, making it suitable for long-term eye use scenarios.

[0020] 2. As described in 1, the multi-layered composite structure gives the lens multifunctionality. The polyvinyl alcohol polarizing layer filters out stray reflections, the niobium oxide infrared blocking layer reduces the impact of heat radiation, the silica hardening layer enhances wear resistance, the titanium dioxide anti-glare layer improves nighttime visual clarity, and the carbon nanotube antistatic layer reduces dust adsorption. The various functional layers work together to balance optical performance and durability, making it suitable for high-demand scenarios such as driving and outdoor activities, while also extending the lens's lifespan.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-4 The gradient dynamic defocus nanolithography fusion multi-point lens and the frame glasses thereon include a base layer 1. Several microlenses 11 and microlenses 22 are distributed on the surface of the base layer 1. The microlenses 11 are of the same size and are distributed equidistantly in a ring along the center of the base layer 1. Four layers are arranged from the inside to the outside. The diameter of the central area spacing of the microlenses 11 is 7.5 mm.

[0028] Several microlenses 12 are arranged in a ring at equal intervals along the central area of ​​the base layer 1, and diffuse outwards. The diameter of the microlenses 12 distributed in the same column increases sequentially from the inside to the outside, and the length of the increase is 0.05 mm. The defocus area composed of several microlenses 11 and microlenses 12 has a diameter of 45.8 mm. The infinite imaging astigmatism band outside the microlenses, which is 0 to 50 nanometers away, is divided into several μm (micrometer) level equilateral, equidistant, and equal-width blocks. The divided blocks are unrecognizable by the retinal photoreceptor cells, cannot form images, and do not produce image jumps. This minimizes and eliminates astigmatism interference to the human eye caused by second-order non-differentiability to the greatest extent, and can achieve dual control of spherical and cylindrical lenses, effectively improving the myopia prevention and control effect. The defocus amount of microlenses 11 and microlenses 12 is +3.00D to +6.00D.

[0029] Several mounting grooves 13 are distributed on the outer ring wall of the base layer 1, and the mounting grooves 13 are equidistantly distributed along the ring of the base layer 1.

[0030] It should be further explained that the surface of the base layer 1 sequentially includes a polarizing layer 2, an infrared blocking layer 21, a hardening layer 22, an anti-glare layer 23, and an antistatic layer 24. The polarizing layer 2 is fixed to the surface of the base layer 1 by adhesive resin. The other side of the polarizing layer 2 is coated with an infrared blocking layer 21. The other side of the infrared blocking layer 21 is coated with a hardening layer 22 by adhesive resin. The other side of the hardening layer 22 is coated with an anti-glare layer 23. The other side of the anti-glare layer 23 is coated with an antistatic layer 24.

[0031] It should be further noted that polarizing layer 2 is made of polyvinyl alcohol, which filters out stray reflected light (such as reflections from water or snow) and improves visual contrast.

[0032] It should be further noted that the infrared blocking layer 21 is made of niobium oxide material, which reduces infrared penetration and is suitable for high temperature or strong light environments.

[0033] It should be further noted that the hardening layer 22 is made of silicon dioxide, which improves the surface hardness of the lens, reduces scratches, and extends its service life. It is suitable for resin lenses. The base layer 1 is made of synthetic resin.

[0034] It should be further noted that the anti-glare layer 23 is made of titanium dioxide, which reduces headlight glare and improves nighttime driving safety.

[0035] It should be further noted that the antistatic layer 24 is made of carbon nanotube coating material, which reduces static electricity and dust adsorption, keeping the lens clean.

[0036] Working principle: This solution uses gradient dynamic defocus nanolithography to precisely distribute microlenses 11 and 12 on the substrate surface, forming a multi-layered annular defocus structure. The microlenses 1 are of the same size and are arranged in four concentric circles with a center spacing of 7.5 mm to ensure the uniformity of defocus. The microlenses 2 adopt a diameter-increasing design (each layer increases by 0.05 mm) and diffuse from the inside to the outside to form a gradient defocus effect. This combined structure can form a dynamic defocus signal in front of the retina, stimulate the inhibition of axial elongation, and thus prevent and control myopia.

[0037] Meanwhile, the lens divides the imaging astigmatism zone outside the defocus area into micron-sized equilateral blocks. These blocks are smaller than the recognition threshold of retinal photoreceptor cells (0 to 50 nanometers) and cannot be perceived, thus avoiding image jump and visual interference. By eliminating the second-order non-differentiable abrupt change at the optical level (such as the step defocus boundary of traditional lenses), the lens significantly reduces astigmatism interference, achieving dual-effect synergistic control of spherical lens (myopia correction) and cylindrical lens (astigmatism correction). In addition, the diameter of the defocus area is strictly controlled at 45.8 mm, covering the main field of view of the human eye, ensuring the full coverage of the control effect.

[0038] The lens achieves comprehensive protection through five functional coatings (polarizing layer 2, infrared blocking layer 21, hardening layer 22, anti-glare layer 23, and antistatic layer 24). The polarizing layer (polyvinyl alcohol material) can filter out stray reflected light from water surfaces, snow, etc., improving visual contrast and making it suitable for outdoor scenes. The infrared blocking layer (niobium oxide) selectively absorbs infrared waves, reducing heat radiation penetration in high-temperature environments and protecting the retinal tissue.

[0039] The hardening layer (silicon dioxide) enhances the lens's scratch resistance and extends the lifespan of the resin lens through a high-hardness coating. The anti-glare layer (titanium dioxide) utilizes the scattering principle of nanoparticles to reduce the glare effect of strong light sources such as car headlights at night, improving driving safety. The antistatic layer (carbon nanotube coating) eliminates surface static charge through a conductive network, preventing dust adsorption and maintaining optical clarity. All layers are tightly bonded together using resin adhesive or coating processes, ensuring defocusing function while also considering environmental adaptability, durability, and ease of cleaning, forming a multi-dimensional eye protection system.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
