If you add up how much time the average American spends looking at a screen per year, it comes to 49 days. That’s 1,176 hours!This statistic is not intended to hurl you into an existential crisis (though hurl you it might), but rather to alert you to the fact that we interact with screens way more than we think — so we should be aware of how they impact our health and what we can do to practice screen time in the safest way. Like self-care, but make it techie.Enter: dark mode, an interface that uses a dark color scheme instead of light and can help reduce eye fatigue, glare, and blue light. These days, you’d be hard-pressed to find an app or device that doesn’t offer it.
“With people spending most of their waking hours on screens, constant exposure to blue light is taking a toll on eyes and health,” says Justin Barrett, CEO Healthe, a company that creates eye safe technology. “The high-energy blue light emitted by our screens has been linked to several visual symptoms categorized by the eye care community as digital eye strain or computer vision syndrome, as well as disruption of circadian rhythm (our body clock). Sleep disruption is also a serious concern, especially among children and adolescents, who are more likely to be sensitive to its consequences like persistent fatigue, poor appetite, and sleep disorders. We should be cautious about the potential long-term effects and accumulated exposure to LED-lit displays.”Related StoriesThese Are The Coolest Apps You Haven’t Heard OfInstagram Explore Is Getting A MakeoverBarrett says using a blue light filter like ZAGG VisionGuard for phones and tablets or wearing glasses with a blue light filter covering a range up to 455nm can protect against the effects of blue light. But another easy way to limit blue light exposure is to enable on dark mode on your devices. Ahead, here’s how to do it. (Also, it might save battery life!)
