Blue Light: 4 Facts You Need to Know


According to a report published by CNN in 2016,Americans commit over ten hours a day to screen time. Whether you’re writing a report on your desktop or checking Instagram on your smartphone, you’re exposing your eyes to visible blue light. Learn more about blue light, and discover how you can protect your eyes.

Sunlight is the Main Source

You might have thought that computers and tablets were the main sources of blue light, but we receive most blue light from the sun. Blue light is the portion of the visible light spectrum that has the shortest wavelengths but highest energy, so we’re exposed to blue light as soon as we step outdoors. However, digital devices are also responsible for emitting blue light, such as smartphones, electronic notebooks, and flat-screen televisions.

Blue Light Can Increase the Risk of Macular Degeneration

Blue light penetrates the inner lining of the back of the eye, also known as the retina. Studies have shown that excessive exposure to blue light from the sun may increase the risk of macular degeneration, known to cause a variety of vision impairments such as complete vision loss.

Digital Eye Strain

When you’re staring at a computer for a significant amount of time, you might experience eye discomfort or even headaches. These side effects are known as digital eye strain, and they’re caused by blue light exposure. Eye doctors suggest wearing computer glasses or updating your current lenses to protect from blue light.

Essential for Good Health

While it’s important to protect your eyes from excessive exposure to blue light, some blue light exposure is essential for your overall health. Studies have proven that high-energy visible light increases alertness, improves memory, and boosts mood.
