It’s no secret screen time has soared during the pandemic1. Especially for those able to work from home, you might oscillate from virtual meetings to online happy hours to a feel-good TV series on Netflix. And repeat. With all this skyrocketed screen time, the thought might have crossed your mind once or twice: Should I invest in a pair of blue-light-blocking glasses? These lenses, meant to filter out the blue light in your surroundings, are practically exploding in popularity as we continue to bombard our retinas with LED-backlit screens—you can snag a pair for anywhere from $12 to $95.
