        Scientific research shows that natural light is a mixture of red, yellow and blue light. Blue light is considered relatively dangerous because of their short wavelength, relatively high energy and penetrating power. But not all blue light is dangerous. Only blue light with a wavelength near 450nm can penetrate the cornea and lens and reach the retina directly, which is truly harmful blue light. The blue-light removal masterbatch produced by our company is made of composite nanomaterials. The anti-blue light masterbatch produced by our company can absorb ultraviolet light and short-wave blue light below 500nm. It can be used to produce anti-blue light films or sheets to effectively shield electronic screens such as mobile phones and computers. The high-energy short-wave blue light emitted protects the retina and avoids macular degeneration. It is also used in production workshops that are sensitive to blue light.

Blue light, protects the retina, avoids macular degeneration, and is also used in production workshops that are sensitive to blue light. In recent years, traditional lamps and light sources have been gradually replaced by LED products. LED light sources are favored due to their low energy consumption, low heat, environmental protection, and long life. At the same time, due to their excellent performance, they are used in backlights of LCD displays, projection TVs, etc. Transmissive screens, lighting fixtures, lighting signboards, etc. have great applications in many aspects. At the same time, they also have great potential application value in signal indication, green display, special lighting, etc. The white light emitted by the LED light source can be formed mainly because the blue light with a wavelength of 450 to 455NM excites the phosphor. The lower the wavelength, the stronger the firing ability. However, scientific research shows that these large amounts of high-energy short-wave blue light with irregular frequencies have extremely high energy and can penetrate the lens directly to the retina. Blue light irradiation of the retina will produce free radicals, and these free radicals will cause the death of retinal pigment epithelial cells and the damage of epithelial cells. Decay will cause the photosensitive cells to lack nutrients, causing vision damage, directly causing irreversible damage to the eye nerves, and blue light can even cause macular degeneration and sleep disorders. Usually the factory wavelength of LED light sources is controlled within 500NM, usually 450~455NM or 455~460NM, which are the areas with the strongest radiation damage. And the longer the LED light source is used, the faster the phosphor in the light source attenuates. As a result, the blue light band that the human eye is exposed to becomes more and more intense, causing damage to the human eye. It can be seen that with the widespread use of LED products, the negative impact of blue light on the human body is bound to become an important issue that consumers must pay attention to and worry about. Therefore, how to solve the blue light problem from aspects such as product structure design and product accessories will become a key bottleneck in promoting the development of the LED industry.
