What is Blue Light and Is it Bad? Just as with UV rays, the sun emits blue light naturally. But electronic screens and energy-efficient lighting also emit blue light wavelengths, which can boost our attention, mood, and reaction times, according to Harvard. That can be an advantage during the daytime, but at night, that light color can disrupt our circadian rhythm (a.k.a. our internal clock) by suppressing the body’s melatonin secretion. Translation: Exposure to more blue light especially two to three hours before bed can cause us to get less sleep. It’s worth noting that eye experts maintain that blue light won’t cause blindness or age-related macular degeneration. As retinal disease specialist David J. Ramsey, MD, PhD, MPH, writes for Harvard, average amounts of blue light from our everyday devices aren’t intense enough to damage the retina.
