Although the effects of blue light damage is still largely unknown, studies have shown that blue light is capable of penetrating all the way to the retina (the inner lining of the back of the eye). Some studies have shown that to much exposure to blue light can damage light-sensitive cells in the retina. This causes changes that aren’t dissimilar to macular degeneration, which can lead to permanent vision loss.
Blue light tends to scatter more easily than other visible light. While looking at computer screens and other digital devices, this visual “noise” reduces contrast and contribute to digital eye strain.
Scientific studies have pinpointed blue light as form of light that’s especially aggressive in triggering sleeplessness. Blue light suppresses melatonin production for more than twice as long as other light wavelengths, and alters circadian rhythms by twice the degree.
Interference with the body’s 24-hour circadian rhythms can have a significant effect on health, creating problems with the cardiovascular, metabolic, and immune systems, disturbing mood, and compromising cognitive function. When your circadian rhythms are out of whack, you think, feel, and perform below your best—and over time, your health can be put at risk.
