Origin

Blue light is a term you may have heard used when discussing either sleep or eye strain, but what is it and where does it come from? Blue light is a term used to describe light on the visible spectrum that appears blue; it has the shortest wavelength and therefore the most energy. The sun is actually the main source of blue light that we are exposed to. Other potential sources are fluorescent lights, LED’s, or electronic displays like computer screens.

Effects

Viewing blue light throughout the day has been shown opens in a new window to boost alertness, help memory, and assist in maintaining a healthy circadian rhythm. Before the use of screens and fluorescent lights, people’s absorption of blue light mostly ended once the sun went down. Now that people can use screens and artificial lights whenever they want, they are introducing blue light and a boost of alertness at night. The result? People can alter their circadian rhythms, making it harder to sleep. Most devices now have ways to reduce the amount of blue light produced.
