Perhaps you’ve heard the term “blue light”, but aren’t sure if it affects you or not. There are definitely some misconceptions about blue light, where it’s found and the potentially harmful effects, so hopefully this post can help to shed some ‘light’ on the situation.
Where is blue light found?
Blue light is everywhere. Smartphones and other digital devices have been targeted as the main blue light culprits, but the truth is, sunlight is the main source of blue light. Being outdoors during daylight is where most of us get the majority of our blue light exposure. There are also many man-made, indoor sources of blue light, such as fluorescent and LED lighting and flat-screen televisions.
