The digital world has created one inevitability: we all spend a lot more time in front of screens, whether it’s your computer, phone, or tablet-like device. While you could argue the dangers and downsides of what it does to your attention span, there’s a more direct issue worthy of your attention — is all of the blue light from those screens bad for your health?
In particular, does blue light damage your eyes, disrupt your sleep, or, possibly, something worse?
There’s quite a bit of misunderstanding about the origins, utility, value, and danger that blue light poses, and this episode clears the confusion and demystifies the true dangers.
In this episode of That’s Healthy, Right? we explain the benefits (yes, benefits) of blue light and its effects on the human body, the importance of your circadian rhythms and melatonin production, a warning about wearing blue light glasses, and the 20/20/20 rule for healthy vision.
