Introduction of anti-blue light protective film

With the development of science and technology, mankind has entered the "screen era". However, while science and technology have brought us convenience, health has drifted away from us, and the harm to our eyes and vision has become more and more serious. Compared with the daytime, looking at a mobile phone or computer screen at night after turning off the lights, the eyes will feel particularly tired. This in the end is why? Studies have shown that the culprit that causes eye fatigue is blue light. Blue light has the greatest impact on pigmented epithelial cells, followed by white light, red light again, and green light the least.

There are high-energy short-wave blue light with different peaks in the light of mobile phones, computers, projectors, LED desk lamps, and car headlights that we come into contact with. Excessive high-energy blue light enters people when working and living in a lighting environment that contains more blue light. Eyes will produce a lot of free radicals. Antioxidants in the body cannot completely eliminate excess free radicals. Excess free radicals will accelerate the oxidation of the retinal macula. Blue light that is not absorbed by the macula will also directly damage visual cells. Excessive free radicals can also oxidize and damage the retinal pigment epithelial cells, making the retinal pigment epithelial cells unable to provide nutrition and metabolism to the visual cells normally, resulting in poor nutritional supply of the visual cells, and ultimately leading to the death of the main visual cells in the macula, and milder cases of eye fatigue , The severe ones will cause vision loss, the principle is shown in Figure 1 below:

Our company's self-developed anti-blue-light protective film for the new type of eye protection film has excellent anti-ultraviolet and anti-blue light effects, high light transmission, good clarity, low haze, and good weather resistance. This product can filter short-wave blue light, and is specially developed to solve the problem of easy damage to the eyes caused by blue light emitted by various light sources such as various LED displays and car headlights. The product performance is better than the full UV protection film. The comparison of blue light blocking effects of products is shown in Figure 2 and 3 below:
