The Dangers of Blue Light and What You Can Do
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.
To put this in perspective, that means that each of us spends 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 the 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 causes them to hold electronic devices closer to their faces, both of which allow more blue light to penetrate the eye.
Fortunately, cutting edge technological solutions to this growing epidemic exist. Crizal Prevencia lenses are special lenses specifically designed to selectively filter out blue light, enhancing visual comfort and minimizing eyestrain. These lenses are embedded with the Smart Blue Filter feature help reduce exposure to Harmful Blue Light. Offered in select premium lenses, including Varilux®Digital, Eyezen™+ and Transitions® lenses, they can be combined with Crizal Prevencia for the ultimate protection against harmful light.
Patients who spend hours on electronic devices are at increased risk of eyestrain and glare, macular degeneration or problems falling asleep at night. For more information about blue light and how to protect yourself, contact your eye doctor today.
