Sunlight is the main source of blue light, and being outdoors during daylight is where most of us get most of our exposure to it. But there are also many man-made, indoor sources of blue light, including fluorescent and LED lighting and flat-screen televisions.

This light is easier on our eyes, especially at night. As we get closer to the higher energy side of the spectrum, light becomes more tiresome for our eyes to process. Blue light occupies the highest energy portion of the visible spectrum. It penetrates all the way to the retina in the back of the eye.
