Description

Technical Field

[0001] The utility model relates to the technical field of lens manufacturing, in particular to a visual fingerprint-proof lens and a finished lens. Background Art

[0002] With the progress of science and the improvement of people's living standards, various lenses have begun to enter people's daily lives and become indispensable tools. Lenses are most commonly used as products to protect or assist the eyes in working, and their appearance frequency in daily scenarios is getting higher and higher. The general surface of the lens is smooth and flat. During use, it is inevitable that obvious fingerprint marks will be left on the lens due to finger pressing. Generally, fingerprint marks are composed of oily substances on the human body surface. Unless wiped or cleaned, the fingerprint marks will always adhere to the lens surface, which may cause visual interference to the people using the lens and affect the appearance neatness of the lens at the same time.

[0003] In the prior art, a part of the transparent lens is often replaced with a coating with anti-oil stain function, but the effect is often not good. It cannot completely resist the oil stain of fingerprints, and can only produce a little fingerprint-proof effect in terms of material properties. Fingerprints will still leave obvious visual marks on the lens, and the coating is extremely easy to fall off and fail, resulting in the instability of the lens structure. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a visual fingerprint-proof lens and a finished lens, which can prevent the generation of fingerprints visually and are firm and durable.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Lens reflective plating dots, there are multiple of the lens reflective plating dots, and the lens reflective plating dots are attached to the matrix texture peaks of the first textured surface, and the reflectivity of the lens reflective plating dots is higher than that of the lens substrate;

[0009] A strengthening layer, which covers the first textured surface and the lens reflective plating dots.

[0010] As a preferred technical solution of the visual fingerprint-proof lens, first textured surfaces are provided on both opposite sides of the lens substrate, and the strengthening layers cover both opposite sides of the lens substrate.

[0011] As a preferred technical solution of the visual fingerprint-proof lens, the end of the matrix texture peak is an arc surface.

[0012] As a preferred technical solution of the visual fingerprint-proof lens, the maximum outer dimension of the projection of the lens reflective plating dots on the surface of the lens substrate is less than 0.1 mm; the distance between two adjacent lens reflective plating dots is not greater than 0.3 mm and not less than 0.05 mm.

[0013] As a preferred technical solution of the visual fingerprint-proof lens, the distance between the peaks of two adjacent substrates is less than 0.13 mm.

[0014] As a preferred technical solution of the visual fingerprint-proof lens, the surface roughness range of the first textured surface is Ra1.12 - Ra2.21.

[0015] As a preferred technical solution of the visual fingerprint-proof lens, the first textured surface is composed of a plurality of convex portions on the lens substrate. The convex portions gradually become smaller from the bottom to the top, and the top of the convex portion is the peak of the substrate.

[0016] As a preferred technical solution of the visual fingerprint-proof lens, an anti-oil layer is provided on the side of the strengthening layer away from the lens substrate, and the hydrophobic angle of the anti-oil layer is equal to or greater than 115 degrees;

[0021] The beneficial effects of the present utility model:

[0022] The visual fingerprint-proof lens provided by the present utility model includes a lens substrate, lens reflective plating dots, and a strengthening layer. On one side of the lens substrate, a first textured surface is attached. At each substrate texture peak on the first textured surface, a lens reflective plating dot is attached, forming high-brightness pockmarks with spacing, size, and a reflectivity higher than that of the lens substrate. Then, the lens substrate is soaked in a strengthening liquid and dried to level the surface of the lens substrate and form a strengthening layer. At the same time, the strengthening layer can cover the first textured surface and the lens reflective plating dots, improving the hardness and flatness of the visual fingerprint-proof lens and also enhancing the overall structural stability of the visual fingerprint-proof lens. The combination of the first textured surface and the strengthening layer protects the durability of the lens reflective plating dots.

[0028] The following further elaborates on the present utility model in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model and are not intended to limit the present utility model. Additionally, it should be noted that for the sake of description, only parts related to the present utility model rather than all structures are shown in the drawings.

[0029] In the description of the present utility model, unless otherwise clearly specified and defined, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] In the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0031] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] Specifically, such as Figure 1As shown in the figure, the present utility model discloses a visual fingerprint-proof lens 100, which includes a lens substrate 110, lens reflective plating dots 120, and a strengthening layer 130. Among them, during the manufacturing and forming process of the lens substrate 110, a textured surface will be formed. One of the textured surfaces is retained as the first textured surface, and the remaining outer surfaces of the lens substrate 110 are polished flat; at each substrate texture peak 111 on the first textured surface, there is attached a lens reflective plating dot 120, forming a plurality of high-brightness dots with spacing, size, and a reflectivity higher than that of the lens substrate. Exemplarily, the surface roughness range of the first textured surface is Ra1.12 - Ra2.21. Due to the first textured surface on the surface of the lens substrate 110, the lens reflective plating dots 120 will only settle and form at the substrate texture peaks 111 on the surface of the lens substrate 110; then the lens substrate 110 with the above characteristics is soaked in a strengthening liquid and dried to form a leveling coating on the surface of the lens substrate and form a strengthening layer 130. At this time, the surface of the lens substrate 110 will be attached with the strengthening layer 130, and all of the first textured surfaces of the lens substrate 110 will be filled by the dried strengthening layer 130, presenting a smooth surface, which improves the hardness and flatness of the visual fingerprint-proof lens 100; the strengthening layer 130 can cover the first textured surface and the lens reflective plating dots 120, and also improves the overall structural stability of the visual fingerprint-proof lens 100. The combination of the first textured surface and the strengthening layer 130 fixes the lens reflective plating dots 120 on the first textured surface of the lens substrate 110, protecting the durability of the lens reflective plating dots 120 and having better strengthening performance. When the human eye observes the visual fingerprint-proof lens 100 from the front, due to the existence of the lens reflective plating dots 120, the focus will be concentrated on the lens reflective plating dots 120 for the first time, making it difficult to detect the transparent fingerprint. The fingerprint problem can be improved by reducing the visibility of the fingerprint in the visual effect. Tiny lens reflective plating dots 120 are attached to the surface of the lens substrate 110, and at the same time, the fingerprint is also attached to the lens in a highly transparent form. When the human eye sees the lens, the attention is dispersed by the lens reflective plating dots 120 for the first time, and it is difficult to see the existence of the fingerprint, thus ignoring the fingerprint visually.

[0033] Since the lens reflective plating dots 120 are formed by coating attachment, they have a light transmission effect, and are small enough and have gaps between them, so they will not affect the original performance of the lens. Exemplarily, the vision anti-fingerprint lens 100 is applied to glasses. Since the position of the vision anti-fingerprint lens 100 is very close to the eyeball, when wearing the glasses, because the distance between the vision anti-fingerprint lens 100 and the human eye is very close, the wearer cannot focus, and the human eye will not feel the existence of the lens reflective plating dots 120; when other people look at the lens from the outside, at a normal social distance, the lens reflective plating dots 120 will reflect part of the visible light, and the lens reflective plating dots 120 shift the line of sight focus of the person looking directly at the lens, making it difficult to observe the fingerprints on the lens, changing the visual effect, interfering with the human eye's judgment visually, so as to weaken the impact of fingerprints on the clean lens. The above structural designs in terms of vision and performance work together to achieve the anti-fingerprint effect visually and avoid the embarrassment of the lens looking dirty in social occasions.

[0034] Further, first textured surfaces can be provided on both opposite sides of the lens substrate 110. Correspondingly, lens reflective plating dots 120 are provided on both opposite sides of the lens substrate 110, and a reinforcement layer 130 is coated at the same time, which can strengthen the vision anti-fingerprint effect on both opposite sides where the vision anti-fingerprint lens 100 most often functions.

[0035] In this embodiment, the lens substrate 110 is generally formed by injection molding. The first textured surface is composed of a plurality of protrusions on the lens substrate 110. The protrusions gradually become smaller from the bottom to the top. The top of the protrusion is the substrate texture peak 111. The spacing at the substrate texture peak 111 is greater than the bottom peak-valley spacing of the protrusion, which is convenient for making the lens reflective plating dots 120 at the substrate texture peak 111, and at the same time can limit the position of the lens reflective plating dots 120 to prevent them from settling into the peak valleys, enhancing the influence effect of the lens reflective plating dots 120 on the visual effect.

[0036] Specifically, the end of the substrate texture peak 111 is an arc surface, which further facilitates the retention and fixation of the lens reflective plating dots 120 on it. Specifically, the maximum outer dimension of the projection of the lens reflective plating dots 120 on the surface of the lens substrate 110 is less than 0.1 mm; the spacing between two adjacent lens reflective plating dots 120 is not greater than 0.3 mm and not less than 0.05 mm, forming the main anti-fingerprint structure, which can better improve the visual focus of the human eye while not affecting the original function effect of the lens. The spacing of the substrate texture peaks 111 of the first textured surface is less than 0.13 mm, so as to ensure that the lens reflective plating dots 120 attached to the substrate texture peaks 111 present an excellent visual effect. In this embodiment, the spacing between two adjacent lens reflective plating dots 120 is set to 0.13 mm. Through experiments, it is found that when at this spacing, the vision anti-fingerprint lens 100 has the best effect.

[0037] Preferably, an anti - oil layer 140 is added to the visually fingerprint - proof lens 100 with a hardened structure. Specifically, the anti - oil layer 140 is provided on the side of the strengthening layer 130 away from the lens substrate 110, which can reduce the adhesion amount of fingerprints or other oil stains. The visually fingerprint - proof lens 100 increases the lens reflective plating dots 120 through coating. At the same time, in combination with the anti - oil layer 140, the anti - oil performance of the visually fingerprint - proof lens 100 is further improved in both structural and performance aspects, and it is more difficult to see fingerprints on the visually fingerprint - proof lens 100 from the front.

[0038] Specifically, an anti - oil layer 140 with hydrophobic properties can be plated on the surface of the strengthening layer 130. The hydrophobic angle of the anti - oil layer 140 needs to be equal to or greater than 115 degrees, which has a hydrophobic effect while preventing oil stains, and avoids affecting the appearance and use effect of the visually fingerprint - proof lens 100 due to the residual wall - hanging of oil liquid; when a finger presses on the visually fingerprint - proof lens 100, the fingerprints adhering to the surface of the visually fingerprint - proof lens 100 will be much less than those on the lens without the anti - oil layer 140, thus further achieving the fingerprint - proof effect in terms of material properties. Due to the attachment of the strengthening layer 130 on the lens substrate 110, plating the anti - oil layer 140 on the surface of the hardened visually fingerprint - proof lens 100 is also more scratch - resistant than the lens without the strengthening layer 130, improving the performance stability of the visually fingerprint - proof lens 100.

[0039] In this embodiment, the lens reflective plating dots 120 can also be selectively made of REVO coating. The REVO coating technology is a multi - layer reflective optical coating technology, which can effectively reduce light refraction and reflection, improve light transmittance and reduce light loss. Its basic principle is to utilize the refractive index differences of different materials, and through the superposition of multi - layer thin films, make the light in a specific wavelength range be maximally reflected or transmitted, so as to achieve the effect of improving image clarity and color restoration. Therefore, it has good refraction and light - transmitting properties. Exemplarily, when the visually fingerprint - proof lens 100 is applied to glasses, since the lens substrate 110 is mostly made of colorless and transparent materials, the lens reflective plating dots 120 can adopt silver - white REVO coating, which can achieve a better effect of shifting the visual focus, and at the same time, the lens reflective plating dots 120 do not look obtrusive.

[0040] Specifically, in various usage scenarios, the lens substrate 110 often selects different colors as the basic color, such as black sunglasses, various types of color - filter glass slides, etc. The REVO film plated on the matrix texture peaks 111 can also have a fingerprint - proof effect on lens substrates 110 of different colors, as long as the brightness of the REVO coating is controlled to be sufficiently greater than the brightness of the material of the lens substrate 110.

[0041] The finished mirror provided by the present utility model, in addition to including the above-mentioned vision anti-fingerprint lens 100, further includes a frame. The vision anti-fingerprint lens 100 is embedded in the frame, which can not only protect the vision anti-fingerprint lens 100 from being damaged by bumps, but also facilitate the user to hold the vision anti-fingerprint lens 100 and reduce unnecessary direct contact during taking and placing. And when the frame is an injection-molded part, the principle of the above solution can also be applied.

[0042] It can be understood that if the frame also has characteristics such as transparency or other properties that are prone to fingerprint or oil stain residues, a second texture surface can be reserved on the outer surface of the frame substrate. Similarly, a plurality of frame reflective plating points are provided and attached to the peaks of the second texture surface, and the frame reflective plating points are arranged in one-to-one correspondence with the peaks of the second texture surface, further improving the appearance cleanliness and aesthetic performance of the finished mirror. Optionally, in order to improve the strength of the frame, not only can the design idea of the vision anti-fingerprint lens 100 be borrowed to set a strengthening leveling layer on the frame reflective plating points, but also a metal reinforcing member can be penetrated inside the frame substrate to make the frame more durable.

[0043] Obviously, the above-mentioned embodiments of the present utility model are only examples for clearly illustrating the present utility model, rather than limiting the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the claims of the present utility model.
