But now we're constantly bathing in artificial light, most of it blue. Until fairly recently, humans were mostly exposed to natural light during the day and darkness at night. Researchers have determined that blue wavelengths - at the high end of the light spectrum, right before UV - are beneficial during daylight hours because they boost attention, reaction times, and mood. According to the American Optometric Association, 58 percent of Americans suffer from digital eye strain (DES), primarily from their laptop and desktop computers, but also from cell phones and tablets.īlue light itself isn't a bad thing. I often felt like my eyes were red and tired by the end of the day, and wouldn't feel the ache begin to lift until I finally turned off my devices.

I'd heard of blue light blocking glasses before: They were yellow, ugly, and not worth the laughter I would get from both roommates and coworkers if I wore them regularly.īut, I had a problem: For my job, I needed to spend a minimum of eight hours a day staring at a computer screen.

Of course, anyone who has stared at their fourth Zoom of the day knows how tired the eyes can get from constant computer use, but the AAO says that is due to the way we use our devices rather than the light emitting from them.

And yes, while studies have shown that exposure to intense blue light from the sun can raise your risk of cataracts, macular degeneration and other eye conditions, there is just not enough light emitted from your laptop, iPad or phone to cause damage or strain, the AAO has concluded.
