We’ve naturally evolved to take in as much as we need.” (Garg’s own child is in a virtual learning environment, and he’s not worried about their exposure.) To help protect a child’s eyesight and ensure they’re receiving the developmental benefits of natural blue light, make sure they’re getting one to three hours of outdoor playtime a day, said the AOA’s Reynolds, and try to limit their screen time and exposure to bright lights before bed (for better-quality sleep). “But we’re not seeing it being a clinical concern. “It’s really a tough time for parents, and they’re looking to do right by their kids,” said Garg. In fact, their eyes actually need that wavelength from sunlight-a deficiency of natural blue light in maturing eyes can lead to myopia (nearsightedness). Parents with children in remote programs may be tempted to buy a pair of blue-light-blocking glasses for their kids, but most children shouldn’t be wearing them all day.

You can always upgrade to a longer-lasting pair later. If you’re curious about blue-light-blocking glasses, we think it’s smart to start with a cheap pair to see if you notice a marked improvement in your sleep or less eyestrain (although there’s no guarantee). Many retailers sell lenses with a blue-light-blocking filter that can scratch and fade over time, though prescription retailers usually have higher standards and bake the blue-light technology into the lens resin. Sunir Garg, clinical spokesperson for the American Academy of Ophthalmology (AAO) and a professor of ophthalmology at the Retina Service of Wills Eye Hospital. “There’s not a lot of rigorous standardization with the lens manufacturers themselves,” said Dr.
A July 2019 study in Optometry and Vision Science found no correlation between price and advertising claims when comparing the efficacy of cheap ($3), medium ($40), and high-end ($350) blue-light-blocking glasses and sunglasses, so don’t assume you’re getting stronger blocking ability by spending more. Our research also showed that price doesn’t necessarily guarantee effectiveness. But if they’re uncomfortably heavy, you can return them to Amazon. The Tjins do weigh more than half the pairs we tested-0.9 ounces. Our panelists also said these glasses were comfortable to wear because the nose bridge and temple arms didn’t pinch, unlike some of the other glasses we tried.
“I had forgotten that they were on my face,” said Wirecutter's Justin Krajeski. These lenses aren’t completely colorless-they have a very faint orange tint-but our testers didn’t mind. They’re sturdy, with level arms that sit flat on your face, and unlike half the pairs we tested (including the similar WMAO Blue Light Blocking Glasses), they don’t suffer from overly stiff hinges. The classic square frames didn’t overwhelm our testers’ faces, and the plastic is durable and doesn’t twist. These glasses are sold in more than a dozen different translucent colors and patterns, from sea green to leopard, more than any pair we tested.

People who tell you otherwise don’t have the data to back it up. Likewise, a pair of glasses won’t magically cure your headaches or migraines. Short-term exposure to blue light from daily use of digital devices won’t harm your eyes, and there’s no clear answer as to whether yearslong exposure is more dangerous. The actual research is complex, and there’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.
