The Problem: Digital Eye Strain

If you’re like us, you spend several hours a day in front of a computer screen or digital device. The problem is that it isn't natural for us to be continuously looking at a screen. Prolong use of electronic devices may lead to symptoms of digital eye strain also known as Computer Vision Syndrome. Symptoms often include eye strain, eye fatigue, headaches, blurred vision, dried eyes. The American Optometric Association estimates that 50%-90% of computer users suffer symptoms of Computer Vision Syndrome. Are you feeling some of these symptoms?

What is Blue Light?

Blue Light also known as high-energy visible blue light (HEV) has high frequency and short wavelengths similar to UV light.

"Blue light is something we're getting exponentially more exposed to because of our transition to a digital lifestyle," says David Friess, O.D., a Philadelphia-based research consultant. "Digital reading is not something we were designed to do."

The American Optometric Association mentions a July 2015 study in the journal Free Radical Biology and Medicine, found that the more chronic the exposure to blue-light-producing LED lights, the more free radicals in the eye. This may contribute to aging of the eye and age-related vision problems in the long term.

Sleep Disruption

At night, blue light can disrupt our circadian rhythm, by reducing the natural release of melatonin. Blue light tricks our brain into believing that it is day-time, which makes falling asleep more difficult and lowers our sleep quality. Circadian disruption can produce serious downstream effects that have long term health consequences.
