How To Avoid Computer Eye Strain

With our hectic lives now, more then ever, we are spending countless hours on our computer, smart phones and other digital devices. Spending this much time on digital devices can lead to eye fatigue and strain but there is a way to reduce this and that’s with a custom pair of prescription computer glasses. Gary Heiting, OD at All About Vision has some great information on how they work.When you work at a computer for any length of time, it’s common to experience eye strain, blurred vision, red eyes and other symptoms of computer vision syndrome (CVS). This is because the visual demands of computer work are unlike those associated with most other activities.If you’re under age 40, eye strain or blurred vision during computer work may be due to an inability of your eyes to remain accurately focused on your screen or because your eyes have trouble changing focus from your keyboard to your screen and back again for prolonged periods. These focusing (accommodation) problems often are associated with CVS.If you’re over age 40, the problem may be due to the onset of presbyopia — the normal age-related loss of near focusing ability. This, too, can cause CVS symptoms.What can you do? For starters, have a comprehensive eye exam to rule out vision problems and update your eyeglasses prescription. Studies show that even small inaccuracies in your prescription lenses can contribute to computer vision problems.*If your glasses are up-to-date (or you don’t need prescription eyewear for most tasks) and you continue to experience eye discomfort during computer work, consider purchasing customized computer glasses. These special-purpose glasses are prescribed specifically to reduce eye strain and give you the most comfortable vision possible at your computer.

Why computer glasses?

Computer glasses differ from regular eyeglasses or reading glasses in a number of ways to optimize your eyesight when viewing your computer screen.Computer screens usually are positioned 20 to 26 inches from the user’s eyes. This is considered the intermediate zone of vision — closer than driving (“distance”) vision, but farther away than reading (“near”) vision.Children and young adults who need prescription eyeglasses usually are prescribed single vision lenses. These lenses correct the wearer’s nearsightedness, farsightedness and/or astigmatism, and the shape of the lens inside the eye automatically adjusts to provide the extra magnifying power required for computer vision and near vision.When a person’s close-up vision becomes less clear due to presbyopia after age 40, this age-related loss of natural focusing power affects reading and seeing a smartphone or computer vision clearly and comfortably. Bifocals  can provide clear distance and near vision, but intermediate vision (needed for computer use and seeing your smartphone) often remains a problem. And progressive lenses or trifocals, though they offer some help for intermediate vision, often don’t have a large enough intermediate zone for comfortable computer work.Without computer eyeglasses, many computer users often end up with blurred vision, eye strain, and headaches — the hallmark symptoms of computer vision syndrome. Worse still, many people try to compensate for their blurred vision by leaning forward, or by tipping their head to look through the bottom portion of their glasses. Both of these actions can result in a sore neck, sore shoulders and a sore back.Though they sometimes are called “computer reading glasses,” it’s best to call eyewear designed specifically for computer use “computer glasses” or “computer eyeglasses” to distinguish them from conventional reading glasses.Generally, computer glasses have about 60 percent the magnifying power of reading glasses. But the optimal magnification depends on how far you prefer to sit from your computer screen and how close you like to hold your digital devices.Computer glasses put the optimum lens power for viewing your computer screen right where you need it for a clear, wide field of view without the need for excessive focusing effort or unhealthful postures. University research also shows custom computer eyewear can significantly increase worker productivity.Come to  Schmidt’s Optical and Hearing™ in Stuart Florida for your new set of computer glasses.
