Harm from bluelight exposure increases with age, research suggests oregonstateuniv
But there is evidence suggesting that increased exposure to artificial light is a risk factor for sleep and circadian disorders, Giebultowicz said. And with the prevalent use of LED lighting and device displays, humans are subjected to increasing amounts of light in the blue spectrum since commonly used LEDs emit a high fraction of blue light.
"This technology, LED lighting, even in most developed countries, has not been used long enough to know its effects across the human lifespan," she said."There are increasing concerns that extended exposure to artificial light, especially blue-enriched LED light, may be detrimental to human health.
In the meantime, there are a few things people can do to help themselves that don't involve sitting for hours in darkness, the researchers say. Eyeglasses with amber lenses will filter out the blue light and protect your retinas. And phones, laptops and other devices can be set to block blue emissions.
