What is Blue Light?
We are privileged to live in an advanced age at the turn of the 21st century. Especially in Manhattan, you can’t walk down the street without seeing someone look at their phone. 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 electronic devices such as computer screens and smart phones. This 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 (though statistics for NYC residents must be higher). 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. Children are also at risk 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.
Prevention Using Prevencia Lenses
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 boast a special state-of-the-art filtering agent within the lens material itself that duplicates elements in the eye, called ocular lens pigment and melanin, which the body naturally produces on its own, and which help filter out just the right amount of blue light entering the eye to protect against unfettered blue light penetration, while allowing proper visual contrast.
Crizal Prevencia lenses are the first lenses to block UV and blue light with a clear lens. This significant breakthrough allows you to wear regular, clear lenses but still protect your eyes from the harmful rays known to cause eye diseases such as cataract and ARMD.
The filters in your lenses will allow you to go about your day without having to worry that you are harming your eyes. Whether you sit at a computer all day, use a smart phone or spend long periods of time outside in NYC, Prevencia lenses will keep your eyes safe. They continue to let the safe, essential light through but block the harmful rays.
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.
