What This Product does? The VizoBlueX Anti-Blue Light Monitor Screen Protector Panel has been developed for people who spend many hours in front of their PC monitors. The product has several coatings’ layers. Each of these layers has its special function such as blue light reduction, anti-flicker, scratch and crack resistance. The VizoBlueX Protector maintains the crystal clear picture of your PC monitor as it doesn’t distort or change any colors of the picture. What Blue Light Is: Blue light is found in all products which use LED light such as PCs, Cell Phones, Tablets, Game machines and TVs. Blue light possesses the most energy among all types of visible light. Therefore, when blue light reaches the retina it damages it and causes many eye problems. Prolonged exposure to blue light leads to dry eyes, eye strain and fatigue. It can even cause serious eye diseases such as cataract, macular degeneration and myopia. Blue light impacts not only the eyes but it also may trigger skin diseases and reduce your work productivity. Numerous studies have confirmed blue light reduces the hormone melatonin which in its turn deteriorates your sleeping quality. Low melatonin levels and not enough sleep make you more vulnerable to depression as well. By changing your melatonin levels and sleep patterns, blue light can also impact on hunger hormones, thus increasing the risk of obesity. How Much Blue Light Is Reduced? The VizoBlueX Anti-Blue Light Monitor Screen Protector Panel blocks 100% of UV light and blocks blue light between 380nm to 495 nm. This spectrum is the one causing retina damage and cell death. The next blue light wave lengths between 450nm and 470nm are responsible for reducing the melatonin level, increasing alertness and heart rate. Afterwards, the blue light from 470nm up to 500nm is healthy for our body. These higher blue light wave lengths are useful for healing sleep disorders and seasonal depressions.
