If youвЂ™d like to try them, below are the fashionable and comfortable pairs we recommend-plus what weвЂ™ve discovered about blue light, and some tips for how to shop for blue-light-blocking glasses online. Our experts agreed that blue-light-blocking glasses are useful to help you fall (and stay) asleep, as they may help counteract the effects of blue light on your sleep-wake cycle. People who tell you otherwise donвЂ™t have the data to back it up. Likewise, a pair of glasses wonвЂ™t magically cure your headaches or migraines. Short-term exposure to blue light from daily use of digital devices wonвЂ™t harm your eyes, and thereвЂ™s no clear answer as to whether yearslong exposure is more dangerous. The actual research is complex, and thereвЂ™s no consensus. The fact is, anyone promising miracles from a pair of blue-light-blocking glasses is probably selling something. To find out the truth, we tested 13 pairs of glasses, read nearly two dozen studies, and interviewed three optometrists, two sleep experts, two eyeglasses providers, a medical doctor, and an ergonomics expert. But most light sources (including the sun) produce blue light naturally and always have, so why are we suddenly trying to block it? And do these glasses do what they claim? The answer is murky, but we can tell you what scientists actually know about the dangers of blue light-and suggest some sturdy and stylish pairs of blue-light glasses you may want to try. If you believe the hype, blue-light-blocking glasses will prevent headaches, decrease eyestrain, and help you sleep like a baby.
