Blue light is a color within the visible light spectrum and the reason our sky appears blue. Although blue light is essential in our daily live, overexposure via artificial sources such digital screens and electronic devices leads to digital eye strain symptoms (eye fatigue, dry eyes, blurred vision, headaches) myopia and vision loss. Children are especially vulnerable to the hazard of blue light resulting in reduced learning abilities.

Blue light is everywhere in our world. It used to be that the only source of blue light was from the sun. Now we have brought blue light inside by way of digital screens (found on TVs, Smartphones, computers, laptops, tablets and gaming systems), electronic devices, LED and fluorescent lighting.

Natural Blue Light v. Artificial Blue Light

Blue light wavelengths are everywhere and surround us. In fact, they’re the reason the sky appears blue. These short blue wavelengths collide with air molecules, which causes the blue light to scatter and makes us process the sky as blue. They’re also a natural form that helps to regulate the body’s sleep and wake cycles, also known as your circadian rhythm. Blue light also helps to boost your alertness, elevate your moods, heighten your reaction times and increase your overall feeling of wellbeing. Artificial blue light sources include electronic devices and certain types of lighting.

Concern about Blue Light Exposure

As one of the shortest, yet highest energy wavelengths in the light spectrum, the blue light flickers easier and longer than other types of weaker wavelengths. This flickering casts a glare that reduces your visual contrast, affecting clarity and sharpness. This can cause eye strain, physical and mental fatigue and headaches if you use your electronic devices or sit in front of a computer all day.

Our eyes have not evolved to provide filters against this type of artificial light. Prolonged exposure to blue light may lead to macular cellular damage, which may lead to loss of vision.
