Description

[Technical field]

[0001] The utility model relates to the technical field of lenses and diving goggles, in particular to a lens substrate, a lens and a swimming goggle. [Background technology]

[0002] At present, when users use swimming goggles, the lens surface often absorbs dust, water mist, etc. due to factors such as static electricity, thus affecting the line of sight. The traditional cleaning method is to spray water vapor, hydrophilic detergent, etc. on the lens surface, and then wipe the surface with a lens cloth. However, the effect of this type of cleaning method lasts for a short time, causing users to frequently clean the lens surface, which is inconvenient and affects the user experience. In addition, the fine particles remaining in the lens cloth may also scratch the lens surface.

[0003] In view of this, it is necessary to provide a lens substrate, a lens and a swimming goggle to overcome the above defects. [Contents of the utility model]

[0004] The utility model aims to provide a lens substrate, a lens and a swimming goggle, aiming to improve the problem that the existing lenses are easy to absorb dust and water mist, resulting in the need for frequent cleaning, thereby improving the protection effect on the lens surface and preventing the lenses from being easily scratched.

[0019] In order to make the purpose, technical solution and beneficial technical effect of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described in this specification are only for explaining the utility model, and are not intended to limit the utility model.

[0020] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0021] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0022] In an embodiment of the present invention, a lens substrate is provided, including a base layer 10 , two silicone resin layers 20 and two hydrophilic layers 30 .

[0023] The base layer 10 is one of a PC (Polycarbonate) layer, a PMMA (PolymethylMethacrylate) layer, a PET (Polyethylene Terephthalate) layer, and a TAC (Triacetyl Cellulose) layer, and is made of a transparent material.

[0024] Two organic silicone resin layers 20 are respectively attached to opposite sides of the base layer 10. The organic silicone resin layer 20 can provide the lens with an anti-reflection effect, which can increase the light transmittance from 88% to 92%, and the hardness reaches HB level, which has an excellent anti-scratch effect.

[0025] The two hydrophilic layers 30 are respectively attached to the sides of the two silicone resin layers 20 that are away from each other. That is, a hydrophilic layer 30 is connected to each side of the base layer 10 through a silicone resin layer 20. The hydrophilic layer 30 is a modified silicon oxide layer, for example, a polyvinyl alcohol-silicon dioxide coating modified with SiO2, so as to form a hydrophilic water film, which can effectively reduce the adhesion of fine particles such as dust and oil droplets, and easily carry these fine particles away through the water film.

[0026] It should be noted that the hydrophilic layer 30 is composed of nano-silica particles and super-hydrophilic functional groups. The SiO2-modified polyvinyl alcohol-silica coating has good hydrophilicity and contains Si-O chemical bonds, which can easily form chemical bonds with the activated silicone resin layer 20 to enhance the ability of the hydrophilic layer 30 to be fixed on the surface of the base layer 10.

[0027] In an exemplary embodiment, the hydrophilic layer 30 includes: 0.70-1.05 wt % of modified silicon oxide particles, 98.65-99.30 wt % of water particles, and ≤0.30 wt % of other material particles.

[0028] Furthermore, the lens substrate further includes a protective layer 40. The protective layer 40 is disposed on one side of the hydrophilic layer 30 away from the silicone resin layer 20. The protective layer 40 is transparent, has a relatively high hardness and a certain hydrophilicity, and can improve the scratch resistance and wear resistance of the lens surface. The protective layer 40 can be formed by stacking multiple thin metal oxide layers, or it can be a silicon compound layer.

[0029] Furthermore, a plating layer 50 is provided between one of the organic silicone resin layers 20 and the adjacent hydrophilic layer 30. The plating layer 50 can be provided with a single color, such as blue, brown, etc., so as to realize the functions of resisting blue light, resisting ultraviolet rays, and filtering excessive light.

[0030] Specifically, the electroplating layer 50 can be a chromium oxide layer for producing green or blue, or a cobalt oxide layer for producing blue, or an iron oxide layer for producing brown or red, or a manganese oxide layer for producing purple. Of course, the electroplating layer 50 can also be an interference color film that uses the interference effect of light to produce color, such as a titanium dioxide film or a silicon oxide film.

[0031] The utility model further provides a lens, comprising the lens substrate as described in any one of the above embodiments, wherein the base layer 10, the silicone resin layer 20, and the hydrophilic layer 30 are all transparent layer structures.

[0032] The utility model also provides a swimming goggle, comprising a goggle frame and the lens as described in the above embodiment.

[0033] In summary, the lens substrate, lens and swimming goggles provided by the utility model are provided with a hydrophilic layer 30 that easily forms a uniform water film on the surface, which is easy to clean. When fine particles such as dust are adsorbed on the lens surface, these fine particles can be taken away with the flow of the water film, which is conducive to keeping the surfaces of both sides of the lens clean and convenient for users to use. In addition, the silicone resin layer 20 can stably combine the hydrophilic layer 30 on the base layer 10, thereby increasing the service life of the lens.

[0034] The present invention is not limited to what is described in the specification and implementation modes, and therefore, additional advantages and modifications can be easily realized by those familiar with the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
