Description

Technical Field

[0001] This utility model relates to the field of optical thin film technology, and in particular to a red light eye protection film. Background Technology

[0002] In today's society, electronic devices have become an indispensable part of people's daily lives and work, such as smartphones, tablets, laptops, desktop computer monitors, and televisions. However, the screens of these electronic devices emit a large amount of light during use, among which blue light is a component that is particularly harmful to the eyes. Prolonged exposure to the blue light from electronic devices can lead to numerous health problems for people's eyes.

[0003] On the one hand, blue light has high energy, which can penetrate the lens of the eye and reach the retina, causing damage to retinal cells. This damage can accumulate over a long period, initially causing discomfort such as eye fatigue, dryness, and soreness, leading to blurred vision and eye pain. Prolonged and continuous exposure to blue light can further cause irreversible damage to the photoreceptor cells in the retina, affecting their normal function and ultimately leading to decreased vision. Children and adolescents are particularly vulnerable, as their eyes are still developing and are more sensitive to blue light, making them more susceptible to its harmful effects. This can potentially impact their normal visual development and increase the likelihood of developing myopia and other eye diseases.

[0004] On the other hand, blue light from electronic devices at night can suppress the secretion of melatonin in the human body. Melatonin is an important hormone that regulates the body's circadian rhythm. Under normal circumstances, its secretion increases at night, inducing sleepiness and ensuring good sleep quality. However, the presence of blue light interferes with melatonin secretion, leading to sleep cycle disorders, making it difficult to fall asleep or reducing sleep quality. This, in turn, affects the body's overall health, causing a series of physiological and psychological problems, such as lethargy, poor concentration, and weakened immunity.

[0005] Existing eye protection products have some limitations. Some eye masks only reduce light using simple materials, but this can also affect screen display quality, leading to color distortion, reduced brightness, and a degraded user experience. Other eye protection products, while claiming blue light filtering, are ineffective at blocking harmful blue light and fail to provide beneficial light conversion and regulation. Furthermore, existing eye masks are structurally flawed, often focusing only on a single function, such as blue light filtering while neglecting light optimization and reuse, or having inadequate protective layers, resulting in poor durability and resistance to damage, making them unsuitable for prolonged use.

[0006] To address this issue, a red light eye protection film is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a red light eye protection film that, through reasonable structural design and material selection, effectively filters blue light and converts some of the light into beneficial red light, thereby protecting the eyes from blue light damage and improving the eye-use environment.

[0008] This invention provides a red light eye protection film, comprising a base layer, a blue light filter layer, a spectral conversion layer, and a protective layer.

[0009] The base layer is a transparent and flexible polyester film with a thickness of 40-120μm. As the basic support layer of the entire eye protection film, its flexibility allows it to be used on electronic device screens of different shapes and sizes.

[0010] The blue light filtering layer is located above the base layer and has a thickness of 20-80μm. This layer uses quantum dot material and is coated on the surface of the base layer to filter harmful blue light and reduce the damage of blue light to the user's eyes.

[0011] The spectral conversion layer is located above the blue light filter layer. It uses quantum dots to convert some of the light into beneficial red light. The quantum dot material used has a particle size of 5-20nm and a layer thickness of 10-30μm. It can convert some of the light filtered by the blue light filter layer into red light, thereby providing users with a more comfortable light environment.

[0012] The protective layer is located above the spectral conversion layer and can be a hardened silicone coating with a thickness of 20-60 μm, or a hard-coated glass or hardened PET film. Its function is to protect the internal functional layers from external physical damage and chemical corrosion, and to extend the service life of the eye protection film.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This novel red light eye protection film utilizes a specially designed blue light filter layer made of quantum dot material to effectively filter out a large amount of blue light emitted from electronic device screens, reducing the harmful effects of blue light on the eyes. For users who spend long periods using electronic devices, this significantly reduces the risk of retinal damage caused by blue light exposure, protects the health of retinal cells, and thus prevents vision loss. It is especially beneficial for children and adolescents whose eyes are still developing, helping to prevent myopia and other eye diseases caused by blue light stimulation.

[0015] The spectral conversion layer uses quantum dot materials to convert some light into beneficial red light. Red light has a relatively long wavelength, which is less irritating to the human eye, providing users with a softer and more comfortable visual experience and reducing eye fatigue and discomfort. This light conversion function can also improve the user's visual experience when using electronic devices for extended periods, alleviating symptoms such as dryness and soreness in the eyes caused by prolonged screen viewing, and improving eye comfort.

[0016] The base layer is made of a transparent and flexible polyester film, allowing the eye protection film to easily conform to the screens of electronic devices of different shapes and sizes, making it widely applicable and meeting the needs of various electronic devices. Meanwhile, the protective layer can be a hardened silicone coating, hard-coated glass, or hardened PET film, effectively protecting the internal functional layers from external physical damage such as scratches and impacts, as well as chemical corrosion, significantly extending the lifespan of the eye protection film and ensuring long-term product effectiveness.

[0017] Unlike some traditional eye protection products, this novel red light eye protection film achieves blue light filtering and light conversion without causing color distortion or excessive brightness reduction. Its rational structural design and material selection ensure that while protecting the eyes, it maximizes the preservation of the original display effect of the electronic device screen, providing users with clear and realistic images and colors, thus improving the user experience when using electronic devices.

[0021] 1. Base layer; 2. Blue light filter layer; 3. Spectrum conversion layer; 4. Protective layer.

[0022] The accompanying drawings have illustrated specific embodiments of the present invention, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1 As shown, firstly, a base layer 1 is prepared by cutting a polyester film to a suitable size with a thickness ranging from 40-120 μm, exhibiting good transparency and flexibility. Next, a blue light filter layer 2 with a thickness of 20-80 μm is coated onto the surface of the base layer 1. This blue light filter layer 2 uses quantum dot material, which is uniformly distributed on the base layer 1 through a coating process to effectively filter blue light. Then, a spectral conversion layer 3 is set on the blue light filter layer 2, using quantum dot material with a particle size of 5-20 nm. The thickness of this spectral conversion layer 3 is controlled at 10-30 μm to achieve the function of converting some light into red light.

[0026] The blue light filter layer 2 is primarily used to reduce or block blue light within a specific wavelength range, typically 400 to 500 nanometers, to protect the eyes from harmful blue light. This helps reduce eye fatigue, improve visual comfort, and may have a positive impact on sleep patterns. It works by selectively absorbing or reflecting blue light, significantly reducing the blue light component in the light passing through the layer. Besides quantum dot materials, materials such as dyes, pigments, optical coatings, or other substances that effectively filter blue light can also be used.

[0027] Quantum dots (QDs) are nanoscale semiconductor materials whose optical and electronic properties depend on their size, shape, and composition. When quantum dots are excited, such as by absorbing blue light from a screen, they transition to a higher energy state. Once these particles return to a lower energy state, they emit photons. Due to the quantum confinement effect, quantum dots can emit light of specific wavelengths. In this embodiment, the quantum dots are designed to efficiently absorb high-energy blue light and then re-emit light at a lower energy, typically longer wavelengths of red or amber light. This conversion is based on the energy level transitions of electrons within the quantum dot: when a quantum dot absorbs a blue photon, its internal electron transitions from the ground state to an excited state; subsequently, as the electron returns from the excited state to the ground state, it releases a lower-energy photon. Quantum dots include, but are not limited to, materials based on CdSe, InP, and perovskite systems.

[0028] Finally, a protective layer 4 is set on top of the spectral conversion layer 3. The silicone coating can be hardened to a thickness of 20-60μm, or a hard-coated glass or hardened PET film can be used as the protective layer 4. Through appropriate bonding or other bonding processes, the protective layer 4 is ensured to firmly cover the spectral conversion layer 3 to protect the internal layers from damage.

[0029] When in use, the red light eye protection film of this invention is attached to the screen of electronic devices, such as mobile phones, tablets, computer monitors, etc., to filter blue light and convert some of the light into red light, thereby achieving the effect of eye protection.
