We are privileged to live in an advanced age at the turn of the 21st century. Electronic devices are everywhere in our world today and make our everyday interactions with the world around us ever easier, safer and more convenient. Although many positive effects have resulted from these devices in our everyday lives, a darker, more dangerous side exists to all of this progress and convenience. Blue light, also known as high energy visible light, is emitted by many of these electronics, and is a serious threat to eye health which was previously unknown and irrelevant in generations past.
Living in such an advanced age, each of us, on average, spends roughly 25 hours every week staring at the screen of one of our electronic devices. To put this in perspective, that means that each of us spend more than one entire day, without sleeping, in front of devices that emit blue light that is proven to do serious damage to our visual system. Eyestrain, headaches and fatigue are common side effects. Even more alarming, recent studies indicate that blue light exposure has the potential to increase risk of macular degeneration significantly over time. Those with a history of macular degeneration are at special risk, as well as children, due to large pupils and shorter arms, which cause them to hold electronic devices closer to their faces, both of which allow more blue light to penetrate the eye.
