Blue light, has always been around us, but with increased screen times, the greater the risk of exposure to blue light and their damaging effects. Strong blue light waves are emitted not just from our cell phones and tablets but also laptops, TV screens, and LED lighting.


As the widespread use of smart phones and tablets increases, people are exposed to more and more blue light today than ever before.


Our digital devices emit strong blue light or HEV light which scatters easily, reducing contrast and adding to eye fatigue.



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.
