Options for blocking your device’s blue light

Blue light is similar to that produced by the sun, which means it could prevent our bodies from going into sleep mode.

While the negative effects of blue light are far from settled science, there are some things we know to be true: Blue light is on the spectrum of light visible to the human eye, and seeing a lot of it could affect our circadian rhythms—the cycles that tell us when to sleep or wake up. When it’s sunny and blue light is scattered, it can help us feel better and more alert. But with the surge in artificial blue light from our digital screens, computers, laptops, smartphones, tablets, and LED lighting, researchers are concerned we might be inhibiting our ability to sleep.

If putting away your electronics isn’t an option, consider a simple device designed to block some blue light.
