For the research, the scientists exposed flies to blue LED light for 12 hours every day. Flies that experienced 12 hours of blue wavelength and 12 hours of darkness had shorter lives compared to flies kept in total darkness or those kept in light without blue wavelength.

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.”
