Specific Embodiments

[0030] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer, the following will further describe the present utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0031] Specific embodiments, in combination with Figures 1 to 4 As shown, further illustrate the technical solution of the present utility model. An anti - blue haze coated lens includes a substrate 10, and the surface of the substrate 10 is coated with a film layer 11, a magnesium fluoride film layer 12, a lanthanum titanate film layer 13 and an anti - fog film layer 14 in sequence from inside to outside. The anti - fog film layer 14 is made of a fluoride film material, and the film layer 11 and the anti - fog film layer 14 constitute a functional film layer with the function of preventing the generation of blue haze on the lens surface. This coated lens uses the film layer 11 as a bottom film layer, taking advantage of its good chemical bonding foundation to improve the density between the film layers, thereby preventing the generation of blue haze on the lens surface; the anti - fog film layer 14 made of fluoride not only plays a plastic sealing role but also has excellent water - proof and oil - proof properties, and can effectively prevent the generation of blue haze on the lens surface in a high - temperature and high - humidity environment.

[0032] Further, as a preferred implementation manner rather than a limitation of this solution, the anti - fog film layer 14 is zirconium fluoride, the thickness of the anti - fog film layer 14 is 20 - 50 nm, and preferably, the thickness of the anti - fog film layer is 30 nm.

[0033] In this embodiment, the anti-fog film layer made of zirconium fluoride has wear resistance and durability, making the lens not easily scratched or worn to leave marks, reducing the condensation of fog on the lens surface, and thus reducing the risk of blue fog generation on the lens surface. At the same time, the anti-fog film layer made of zirconium fluoride is not easily decomposed in a high-temperature environment and has excellent tolerance to most chemical substances, such as being acid-resistant, alkali-resistant, and oxidant-resistant, enabling the lens to be used in a variety of environments.

[0034] Further, as a preferred implementation manner rather than a limitation of this solution, the film thickness of the film layer 11 is 30 - 60 nm. Preferably, the film thickness of the film layer 11 is 40 nm.

[0035] In this embodiment, the film layer has high hardness and corrosion resistance, which can protect the lens from scratches and improve the corrosion resistance of the lens. At the same time, the film layer not only has a certain light transmittance in the visible light range but also has good characteristics in the infrared light band.

[0036] Further, as a preferred implementation manner rather than a limitation of this solution, the film thickness of the magnesium fluoride film layer 12 is 10 - 40 nm. Preferably, the film thickness of the magnesium fluoride film layer 12 is 20 nm, and the film thickness of the lanthanum titanate film layer 13 is 30 - 80 nm. Preferably, the film thickness of the lanthanum titanate film layer 13 is 50 nm.

[0037] In this embodiment, through the low-refractive-index magnesium fluoride film layer and the high-refractive-index lanthanum titanate film layer, the lens has strong anti-reflectivity, improves the light transmittance of the lens, and reduces glare. At the same time, the low-refractive-index magnesium fluoride film layer as a primer layer can increase the adhesion between the film layer and the substrate and improve the stability of the multi-layer film system lens.

[0038] Further, as a preferred implementation manner rather than a limitation of this solution, the substrate 10 can be a glass substrate, a resin substrate, or a nylon substrate. Preferably, the substrate 10 is a glass substrate;

[0039] Among them, the glass substrate can be made of sapphire material.

[0040] In this embodiment, compared with the organic glass and mineral glass watch glasses, the glass substrate made of sapphire material has a hardness of up to Mohs 9, is not easily reflective and scratched, ensures the overall hardness of the lens, reduces the probability of damage, and at the same time, sapphire also has waterproof characteristics, further improving the anti-fog performance of the lens.

[0041] Further, as a preferred implementation manner of this solution rather than a limitation, the uncoated lens needs to be stored in an environment with a temperature of 23°C ± 2°C and a humidity of 50% ± 5%. Before coating, the lens needs to be cleaned first to achieve the best cleanliness;

[0042] Among them, different cleaning methods are adopted according to different lens materials. For example, when the lens is made of glass substrate, the cleaning method can be rinsing with pure water or wiping with a special optical glass cleaning solution. When the lens is made of resin substrate, the cleaning method can be washing with warm water and neutral detergent or wiping with a special resin lens cleaning solution. When the lens is made of nylon substrate, the cleaning method is washing with mild soapy water.

[0043] In this embodiment, storing the uncoated lens in an environment with a temperature of 23°C ± 2°C and a humidity of 50% ± 5% can prevent the formation of water mist on the lens surface due to too high temperature or humidity; at the same time, adopting corresponding cleaning methods according to different substrate materials can achieve the best cleanliness of the lens surface, ensure the uniform deposition of the coating layer and improve the bonding force between the coating layer and the substrate, effectively reducing the generation of blue haze on the lens.

[0044] Further, as a preferred implementation manner of this solution rather than a limitation, the substrate 10 is coated by ion source assisted coating method. During coating, The film layer 11, magnesium fluoride film layer 12, lanthanum titanate film layer 13 and anti-fog film layer 14 are coated onto the substrate 10 in sequence.

[0045] Among them, the ion source assisted coating method is a technology that evaporates and deposits the coating material onto the lens in a vacuum.

[0046] In this embodiment, the ion source assisted coating method is carried out in a vacuum environment and at a relatively low temperature, which can reduce the generation of blue haze on the lens caused by too high temperature. The vacuum environment can also prevent the condensation of external fog on the lens surface to generate blue haze; the ion source assisted coating method can also increase the aggregation density of the film layer, reduce the reflectivity of the lens and improve the light transmittance of the lens, thereby reducing the generation of blue haze on the lens; through the ion source assisted coating method, the hardness and corrosion resistance of the film layer can also be improved, thereby improving the durability and reliability of the lens.

[0047] Further, as a preferred implementation manner of this solution rather than a limitation, an optical test is carried out on the coated lens. After the test, When the film thickness of the film layer 11 is 40nm, the film thickness of the magnesium fluoride film layer 12 is 20nm, the film thickness of the lanthanum titanate film layer 13 is 50nm, and the film thickness of the anti-fog film layer 14 is 30nm, the reflectivity effect of the lens is the best while preventing the lens from generating blue haze.

[0048] Specifically, asFigure 3 As shown, it is a graph of the reflectance change of the anti-blue haze coated lens under incident light of different wavelengths, where:

[0049] The X-axis is the wavelength of the incident light, and the Y-axis is the reflectance of the anti-blue haze coated lens. Through Figure 3 As shown, when the wavelength of the incident light on the anti-blue haze coated lens is between 400 nm and 710 nm, the reflectance is less than 0.5%.

[0050] In this embodiment, the coated lens with the film layer and the anti-fog film layer can not only prevent the lens from generating blue haze, but also has good anti-reflectivity for the wavelengths of most visible lights, effectively reducing glare and improving the light transmittance of the lens.

At the same time, due to different industry names, it is not limited to the above names, nor to the English names.
