Computer glasses are specialty eyeglasses made specifically to address the unique visual needs of extended computer and smartphone use. To address these needs, computer glasses are made completely differently, in a number of important ways, from regular eyeglasses and reading glasses.
These significant differences are what make computer glasses absolutely essential for maintaining both your short term visual comfort and long term visual health as you work and play in a world increasingly dominated by computers and smartphones.
To begin explaining the benefits of computer glasses, it is important to point out that computer screens are generally positioned around 20-26 inches from your eyes. This is what eyecare professionals call your “intermediate” zone of vision. Unfortunately, traditional eyeglasses are not made in a way that is conducive to intermediate viewing of the type required by computer work. This often leads to blurred vision, eyestrain and headaches after extended computer use.
Computer glasses, on the other hand, are specifically made to emphasize comfortable intermediate viewing, helping your eyes more easily focus on the computer screen with less effort and making computer viewing over an extended period of time noticeably more comfortable.
Those who spend extended amounts of time on the computer would also be wise to note another factor that often contributes to computer-related discomfort and may even be potentially sight-threatening: blue light.
This high-energy light comes from computer screens, televisions and smartphones, and has been known to cause eyestrain, headaches and fatigue. Recent studies also point to growing evidence that blue light exposure has the potential to significantly increase a person's risk of macular degeneration over time.
Computer glasses are often equipped with special coatings or lenses that are made specifically to filter harmful blue light so that it does not reach your eyes. This makes extended computer use more comfortable and reduces the risk of developing macular degeneration in the future. We are happy to offer the following products: BluTech Lenses, Crizal Prevencia, and Essilor Smart Filter Lenses.
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.
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 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 cause 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. 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.
BluTech , Crizal Prevencia, and Eyezen lenses are three of the best state of the art solutions for maintaining optimum eye health and for prevention of ocular diseases such as macular degeneration, retinal disease, lenticular disease and ocular surface disease. For both indoor and outdoor environments.
These lenses are ideal for all patients who spend hours on electronic devices, complain of eyestrain and glare, have macular degeneration or problems falling asleep at night.
