Blue Light Radiation

In our technology-driven world, we are exposed to more blue light radiation than ever before. from spending increasing amounts of time on digital screens like your smartphone, tablet or computers. Smartphones emit the highest levels of blue light compared to other devices. Because we hold them so close to our face, the risk of developing detrimental effects on our health such as digital eye strain, sleeping disorders and macular degeneration is very real.

Blue light penetrates to the back of the eye, triggering nerves that causes discomfort and eye strain - leading to permanent damage to the eye. Our eyes’ natural filters do not provide sufficient protection against blue light rays from the sun, let alone the blue light emanating from digital devices. Also the suprachiasmatic nucleus, is a tiny region of the brain in the hypothalamus and is responsible for controlling circadian rhythms. These cells are activated by blue light, and when there is a lot of blue light (as when the sun is overhead), the suprachiasmatic nucleus tells the pineal gland not to make much melatonin, and so we stay awake. Fine in the daytime but disruptive at night to our sleep cycle.
