Psst: These Are The Best Blue Light Glasses To Snag, Says A Functional Eye Doctor

Remember when we told you not all blue-light-blocking glasses are created equal? Well, in case you need a refresher, "They all filter out different amounts of that blue light," says functional eye doctor Rudrani Banik, M.D., on the mindbodygreen podcast. That's not to say you absolutely need to filter out all traces of blue light (everyone can tolerate different levels), but if you are hoping to block the most blue light you can, snagging any ol' pair of lenses might not cut it.

She cites a Consumer Reports study conducted in 2016, which looked at the top three blue-light-blocking glasses on the market. Researchers measured these glasses to determine how much blue light they actually block. The results? "Only one of the brands out of three blocked 98% of the blue light," says Banik. "The other brands blocked 30 to 40% of that blue light." 

You're probably on the edge of your seat: Which brand reigned supreme? According to Banik, the winning lenses are called Uvex Skypers, and you can find them online for a mere $10. Pretty compelling, considering you can find lenses five times that price point, and they might not even filter out as much blue light as these Skypers. "You don't have to spend a ton of money to get the value of those blue blockers," adds Banik.

The only thing about these blockers is they're not so discreet—the dark amber lenses look more like tinted sunglasses than a pair of chic readers—but in the name of digital eye strain, it may be worth it.

If you don't wish to give up your clear lenses, that's A-OK. In fact, Banik shares a few other gadgets to help filter blue light, ones that don't require investing in new eyewear. 

"There are some apps you can download to your computer or your phone that will internally remove the blue light," she notes. What's more, these apps sync to your geographic location, so they can adjust the amount of blue light on your screens depending on the time of day (because, as we know, blue is not all bad during the daytime; it's when the sun sets in the evenings that it's time to dial down).
