Product Information

One possible benefit of blue light screen protectors is improved sleep. A 2018 study found that blue light can stimulate the brain and reduce the production of melatonin, a hormone that helps people maintain their circadian rhythm and induce sleep. This should be a key parameter to look for when choosing a blue light screen filter. May distort the color of your screen However, the company does not state whether its products reduce glare, protect against scratches, or repel liquids. There are anti blue light screen protectors that will allow you to see the screen in the normal color without a yellow tint while also offering you protection from blue light.

Cortisol is a hormone which is responsible for waking us up, whereas melatonin is a hormone accountable for helping us to fall asleep. f.lux is a similar program available for Mac, PC, iOS and Android. The issue with both Night Shift and f.lux is that they give screens a reddish or orange tint towards the end of the day – which isn’t ideal for watching Netflix shows or enjoying pretty much anything in its original colors.You may already be aware of software fixes for blue light, such as Apple’s Night Shift setting, which reduces levels of blue light, according to the time in your region, to reduce the intensity of the display: “Night Shift automatically adjusts the colours of your display to the warmer end of the spectrum – making the display easier on your eyes.”

Animal studies and lab studies have raised questions about whether blue light could speed up the process of macular degeneration. Still, eye doctors and researchers do not think there is a verifiable link between using LED or blue-light-emitting devices and AMD. The three attributes we rated in our testing were fit, feel, and clarity. We considered whether their glasses fit snugly and comfortably on their faces, noting when glasses slipped down, pressed too tightly against their heads, needed constant adjustment, or felt too large or small for their faces. (We also made stylistic notes here, too, when a pair seemed particularly on- or off-trend.) For feel, we evaluated how our eyes felt after hours of wear; if we noted short- or long-term improvement in eye strain symptoms over the course of the testing week, those glasses scored higher for feel than others that didn’t give us any noticeable improvement.
