What is Blue Light?
Most of our indoor lifestyle now revolves around digital devices. These devices give us artificial lights as what we now call “blue light”. The artificial blue light associated with LED and screen-based OLED illumination from digital devices emits 430 nanometers to 500 nanometers - with an intense spike at 455 nanometers making it one of the shortest, highest energy wavelengths. The most harmful nanometer range is 415-455 which is now called high-energy visible light or HEV. This harmful digital blue light operates from laptops, tablets and mobile phones that we use 24/7. This makes our eyes at risk as the use of modern technology makes it easy to exceed healthy levels of blue light, especially at night.
