Anti-Blue Light Screen Filter for 22 inch LED / LCD MonitorsVisible light is light that the human eye can see. This encompasses wavelengths from 400nm to 750nm and consists of all the colors in the rainbow (red, orange, yellow, green, blue, indigo, and violet). Falling off the spectrum of visible light is invisible light, such as those found in UV and IR. We all know the damages that UV rays can cause to your eyes, but we also have to be concerned about blue light. Blue light is a high energy visible light (HEV light) encompassing the wavelengths from 400nm to 500nm (shorter wavelengths equates to higher energy). Blue light is all around us, whether naturally or artificially. LED backlight devices, such as smartphones, tablets, laptops, desktop monitors are all devices that emit artificial blue light. Extended exposure to blue light can lead to severe vision impairments, such as total blindness from cataract or age-related macular degeneration (AMD). Due to its shorter wavelength, blue light also flickers more easily and causes glare, which may be attributed to eyestrain or headaches. Blue light use during the night can also disrupt sleeping patterns by lowering melatonin levels. With so many detrimental effects to blue light, it is important that we take precautionary measures to protect our vision and our health. Anti-Blue light screen filters for LED / LCD monitors block up to 99% of harmful blue light and UV light. All anti-blue screen filters are also TAA compliant and SGS tested to ensure product quality and safety requirements. Installing the screen filter is easy; you do not need to worry about cleaning your screen, air pockets or lining up the screen filter to your monitor. It is easily installed by a hang flap that sits right over the edge of the monitor (optional adhesives are included, though not necessary). All screen filters can also be cleaned with general cleaning equipment without causing harm (a screen cleaning cloth is also included).

Anti-Blue Light ScreenAfter a month of use by several people in office setting, the anti-blue light screen seem to be delivering what is promised, reduced eye strain and clearer images. The one draw back of the screens is the glare. We would like to see this product with anti-glare as well.
Anti-Blue Light Screen Filter for 22 inch LED / LCD MonitorsSeems like working. Good one.
AwesomeAbsolutely adore the blue light filter. Works perfectly, good quality, amazing price, really like how it hangs from the top of my all-in-one. Means I can't use touchscreen, but I just pop it off when I need to. All in all, definitely give it A+++++++++
