Anti Blue Light TV Screen protector: VizoBlueX has been specially created for people who spend many hours in front of their PC monitors or TV screens. The protector has undergone rigorous tests and has been proven to eliminate 100% of UV light; up to 99.6% of the most harmful Blue light (380 to 420nm) and 60% from the entire HEV (High Energy Visible) spectrum between 380nm~480nm. The protector consists of a couple of different layers that provide blue light reduction, anti-flicker, scratch and crack resistance. VizoBlueX preserves the HD picture and all colors of your screen. All devices that use LED light like PCs, Cell Phones, Tablets, Game machines and TVs emit blue light. This type of light has the highest amount of energy of all kinds of light. This is why it is so dangerous for us, humans – it damages the retina and caused dry and red eyes, as well as more serious eye conditions like cataract, macular degeneration and myopia. Scientific studies have proven blue light reduces the hormone melatonin. This changes your circadian rhythms and causes insomnia. This may cause depression in the long run. Blue light can also have an impact on your hunger hormones and become a cause for obesity. VizoBlueX has been developed for PC monitors and TV screens. It does not work with laptops. VizoBlueX does not work with touchscreens. Dry erase markers can be used on the protector. VizoBlueX will cover your screen as well as your screen’s frame. Please, measure the diagonal of your screen before ordering. VizoBlueX is 100% transparent. However, it is tinted in grey or brown due to its blue light properties. Therefore, you should increase the brightness of your screen by 15%.
