Pick your purpose: It's important to pick a screen protector that's specific to your device and fits the exact dimensions of your screen. Keeping lubricating drops next to your computer to use is also a great idea," she says. "Every 20 minutes look 20 feet away for 20 seconds. In addition, Rappaport suggests implementing the 20/20/20 rule. Particularly for the sake of your sleep, positive reviews suggest that these products may be worth trying-that is, of course, if you're willing to spend a few bucks on the experiment. While more research still needs to be done to prove their effectiveness, there is no reason to believe blue light screen protectors could be harmful. "We typically have a blink rate of 18 times a minute, and when we are on screens it is down to around six-this causes dry eye and irritation." "Screens in general cause eye strain," she explains. "The second, more important effect is that blue light can affect circadian rhythms and negatively impact your sleep patterns."Īccording to board-certified ophthalmologist Yuna Rappaport, M.D., MPH, the issue is more about our screens in general. "Some studies suggest that devices like monitors and cellphones have a blue light wavelength that affects vision in two ways: The first is that it's harmful to your eyes and can cause possible long-term damage," Todd Handel, an optician at East Coast Optometry, previously told mindbodygreen. A 2017 review of three studies suggests that there's not currently enough evidence to determine the impact these products have on our eye health and sleep-wake cycles. It's important to note that while there's a lot of anecdotal evidence supporting the idea that blue-light-filtering glasses and screen protectors can help reduce eyestrain, more scientific research needs to be done to back it up. They are meant to filter out a portion of the blue light, without totally changing your screen's appearance or display quality. Find our picks below, and learn how to choose the best blue light screen protector for you.īlue light screen protectors are panels of tempered glass or acrylic that fit the screen of your device. We've done the research to round up the best blue light screen protectors for every type of screen-so you can keep your body functioning at its prime, no matter how many hours you're logging on the computer. But for a lot of us, our workday is tied to a computer. There are ways to limit your exposure, such as less scrolling before bed, or turning off your TV a bit earlier. Overexposure from excessive screen time can also cause eye strain, headaches, and blurry vision. So why does blue light get such a bad rap? Too much artificial blue light can disrupt your internal clock 1. Blue light is naturally produced by the sun, and low exposure to these light waves is necessary to keep our circadian rhythm functioning properly 1. And, to some degree, our bodies depend on it. While blue light screen protectors are a great way to mitigate the effects of artificial blue light, natural blue light waves are actually all around us. It's no secret that we spend more time in front of screens than ever-but here's one thing you might not know: Blue light is not all bad.
