Do Blue Light Blocking Glasses Really Work?

If you have a desk job, or are simply a living, breathing human in the year 2019, chances are you spend a good deal of time in front of a computer screen or at the very least, a smartphone. As such, your eyes are exposed to the blue light that emanates from said devices (although blue light occurs naturally as well), and, as a result may experience some of the side effects of that exposure.

What are some effects of blue light radiation? Kyly Zak Rabin, co-founder of Zak. explains, "The exposure of blue light has long been attributed to an increase in eye strain and visual fatigue but to what extent we are still uncertain, as recent studies are considering the magnitude of its effect. Additionally, it has been determined that excessive blue light exposure can disrupt the circadian rhythm affecting one’s sleep cycle."

Enter blue light-blocking lenses: treated glass for frames can be used to reduce eye strain, but also, supposedly, safeguard against circadian rhythm disruption assuring a more consistent sleep pattern-particularly if you don't power down your devices a few hours before bedtime. We rounded up the best frames with blue light treated lenses, so you can wear them in style, and hopefully, sleep better too.
