What is Blue Light?

All visible light we humans see contains the entire spectrum of the rainbow, from red to violet.  Within that spectrum are blue light waves, which are said to help us stay alert and upbeat.

What gives Blue Light?

Any source of visible light gives off blue light waves.  We get plenty of blue light waves each day from the sun, but after dark we're still exposed to it from many artificial sources.

How does Blue Light affect sleep? 

When the sun goes down, the lack of light signals our bodies to start producing melatonin, the hormone responsible for making us fall asleep.

Before the advent of artificial light, the sun regulated our sleep schedules. But today, we're exposed to light all day and into the night. While exposure to any light waves after dark delays our bodies' production of melatonin, blue light waves can be especially problematic because they keep us alert.

So, what does my phone or computer screen have to do with this?
Compared to fluorescent and incandescent bulbs, LEDs can give off a significant amount of blue light.

Unfortunately for all of us who use tech after sunset, LEDs are used in countless smartphone, tablet and TV screens. Tech products that have a LCD screen, like laptops, iPads and older iPhones, still use LEDs to backlight their displays.

Is Blue Light harmful?
Blue light has been linked to all sorts of issues, from causing digital eye strain to making us blind. There's a lot of conflicting evidence, however, about exactly how harmful (or not) it really is but proceed with caution.

What are Blue Light blocking glasses?
Blue-light blocking glasses have filters in their lenses that block or absorb blue light, and in some cases UV light, from getting through. That means if you use these glasses when looking at a screen, especially after dark, they can help reduce exposure to blue light waves that can keep you awake.

Many blue-light blocking glasses you can buy also claim to help reduce eye strain.

Most are meant to be worn during the day while in front of screens and at night to prevent the blue light of screens from keeping us awake.
