IN AN ideal world, we’d all have hours of screen-free time before bed for a better night’s sleep. But with late-night deadlines, the constant pull of TikTok, Netflix binging, and our increasingly-online social lives, it’s just not happening. The result? Our world is awash in blue light. And the worst casualty of this era is our eyes. That’s where so-called "blue-blockers"—a.k.a. blue-light-blocking eyeglasses for computer use—come in.
“Light, particularly the blue wavelength of light, is one of the strongest regulators of your circadian rhythm,” says Stephanie M. Stahl, M.D., a sleep medicine physician and assistant professor of clinical neurology at Indiana University School of Medicine in Indianapolis. Sunlight, along with blue light from devices like your smartphone and laptop can raise your alertness in the morning, but blue light exposure at night could significantly decrease your body’s production of melatonin—the hormone that’s key for shifting your body into sleep mode. Bottom line: Blue-light-blocking (BLB) glasses could be your first line of defense.
Blue-light-blocking glasses might seem simple. But, the science behind them is complex and a little, er, muddy right now, which can make shopping for your "best" pair difficult. We researched and personally tested dozens of top-selling models over the last year to compare fit, finish, overall design, price, and, of course, effectiveness. If you're ready to upgrade your daily (or nighttime) routine with a pair, here are our picks for the best blue-light-blocking glasses for computer use to help save your eyes in 2023.
