Description

Technical Field

[0001] This utility model belongs to the field of lens technology, specifically, it relates to a biomimetic honeycomb resin lens. Background Technology

[0002] Resin lenses can reflect and oblique light during daily use, which can cause glare and image distortion. To improve the performance of the lenses, a biomimetic honeycomb resin lens has been developed. Summary of the Invention

[0003] In view of this, the technical problem to be solved by this utility model is to provide a biomimetic honeycomb resin lens, which solves the problem of glare caused by reflected light and oblique light on the lens in the prior art.

[0004] To solve the above-mentioned technical problems, this utility model discloses a biomimetic honeycomb resin lens, comprising: a lens; a front surface of the lens is provided with honeycomb-shaped distributed micro-convex lens units, the surface of the micro-convex lens units is provided with an anti-reflection composite film layer, the outer surface of the anti-reflection composite film layer and the inner surface of the lens are provided with a protective film layer, the outer surface of the protective film layer is provided with a hydrophobic film layer, and the surface of the hydrophobic film layer is provided with honeycomb-shaped distributed hydrophobic grooves.

[0005] Furthermore, the width of the groove between the adjacent micro-convex lens units is greater than the width of the hydrophobic groove.

[0006] Furthermore, the aforementioned drainage channel is composed of multiple individual unit channels continuously distributed at intervals.

[0007] Furthermore, the aforementioned drainage channels and trenches overlap.

[0008] Furthermore, the aforementioned antireflective composite film consists of a titanium dioxide film layer, a silicon dioxide film layer, another titanium dioxide film layer, and a magnesium fluoride film layer in sequence.

[0009] Furthermore, the aforementioned protective film layer is a diamond carbon film layer.

[0010] Furthermore, the aforementioned hydrophobic film layer is a magnesium fluoride film layer.

[0011] Compared with the prior art, this application can achieve the following technical effects: This invention features honeycomb-shaped distributed micro-convex lens units on the front surface of the lens substrate. The honeycomb structure filters oblique light, allowing more vertical light to pass through, helping the eye focus on the retina, reducing glare and distortion, compensating for insufficient refractive power of the lens or cornea, and improving visual clarity and contrast. The outer surface of the hydrophobic film layer is provided with a honeycomb texture structure. The hydrophobic grooves increase the surface tension to liquids, making it difficult for water vapor to form micron-sized water droplets after liquefaction. Instead, it forms a water film, which can effectively play a role in preventing fogging and hydrophobicity.

[0012] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time. Attached Figure Description

[0016] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0017] Please refer to Figures 1 to 3 , Figure 1 This is a cross-sectional schematic diagram of a lens according to one embodiment of the present invention; Figure 2 This is a schematic diagram of the surface of a lens according to one embodiment of the present invention; Figure 3 yes Figure 2 A magnified view of a portion of point A in the middle.

[0018] A biomimetic honeycomb resin lens includes: a lens 1; the front surface of the lens 1 is provided with honeycomb-distributed micro-convex lens units 2, the surface of the micro-convex lens units 2 is provided with an anti-reflection composite film layer 3, the outer surface of the anti-reflection composite film layer 3 and the inner surface of the lens 1 are provided with a protective film layer 4, the outer surface of the protective film layer 4 is provided with a hydrophobic film layer 5, and the surface of the hydrophobic film layer 5 is provided with honeycomb-distributed hydrophobic grooves 6.

[0019] The surface of lens 1 is created using nanoimprint lithography. First, a "template" with micro / nano patterns is pre-prepared and imprinted onto an "imprinting adhesive" coated on the substrate surface. The adhesive fills the patterned grooves (hexagons) of the template. After curing, the template is demolded, ultimately forming a micro / nano structure on the substrate surface consistent with the template pattern. Then, using the imprinting adhesive as a "mask," the areas of the substrate not covered by the imprinting adhesive are removed by dry etching (plasma) or wet etching (chemical solution), ultimately forming a permanent pattern on the substrate. The texture on the surface of the hydrophobic film layer 5 is also created using nanoimprint lithography.

[0020] The width of the groove 7 between adjacent micro-convex lens units 2 is greater than the width of the hydrophobic groove 6. The hydrophobic groove 6 is formed by multiple individual unit grooves 8 distributed continuously at intervals. The hydrophobic groove 6 and the groove 7 overlap. The honeycomb texture on the surface of the lens 1 substrate overlaps with the honeycomb texture on the surface of the hydrophobic film layer 5. This design can make the texture on the surface of the lens 1 regular and not messy.

[0021] The antireflective composite film 3 consists of a titanium dioxide film 9, a silicon dioxide film 10, a titanium dioxide film 9, and a magnesium fluoride film 11. The silicon dioxide film 10 and the magnesium fluoride film 11 are low-refractive-index films, while the titanium dioxide film 9 is a high-refractive-index film. The alternating arrangement of high and low refractive-index films can improve the antireflection effect and reduce the reflectivity.

[0022] The protective film layer 4 is a diamond carbon film layer, which serves as an outer wear-resistant coating to improve the scratch resistance of lens 1 without affecting the light transmittance.

[0023] The hydrophobic film layer 5 is a magnesium fluoride film layer. The magnesium fluoride film layer is resistant to acid and alkali corrosion and oxidation. It does not react with water or most organic solvents. It is not easy to age or deteriorate in humid or harsh environments. In addition, the film layer has high hardness, strong adhesion, and excellent wear and scratch resistance.

[0024] This invention features a honeycomb-shaped distribution of micro-convex lens units 2 on the front surface of the lens substrate 1. The honeycomb structure filters oblique light, allowing more vertical light to pass through, helping the eye focus on the retina, reducing glare and distortion, compensating for insufficient refractive power of the lens or cornea, and improving visual clarity and contrast. The outer surface of the hydrophobic film layer 5 is provided with a honeycomb texture structure, and the hydrophobic grooves 6 increase the surface tension to liquids, making it difficult for water vapor to form micron-sized water droplets after liquefaction, but instead forming a water film, which can effectively play a role in preventing fogging and hydrophobicity.

[0025] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
