Trying to Get Some Sleep

Another argument in favor of blue light glasses is that they help you sleep better at night. Researchers agree that blue light from LED devices like your smartphone or laptop holds back the body’s production of sleep-inducing melatonin.

A 2017 study done by the University of Houston found that participants wearing the glasses showed about a 58% increase in their nighttime melatonin levels. “By using blue blocking glasses we … can improve sleep and still continue to use our devices. That’s nice, because we can still be productive at night,” said Lisa Ostrin, PhD, a professor at the university’s College of Optometry, according to a university news release.
