According to the American Optometric Association, computer eyestrain is the most common office-related health problem in America. 60 million Americans are affected by it. The use of computers at home and work continues to increase exponentially. A number of physical and visual symptoms are associated with computer use, including blurred vision, headaches, dry eyes, dry eyes, dry eyes, dry or irritated eyes, fatigue, headaches and other symptoms. Between 50%-90% percent of computer users experience these symptoms. Computer Vision Syndrome (CVS) is a term that describes a group of symptoms such as fatigue, headaches, blurred vision and dry eyes. To resolve the symptoms of CVS, you should visit your eye doctor. This is especially important if you use the computer for more than two hours per day. A simplified explanation of how the brain and eye process visual information is helpful in understanding why computer vision problems occur.
The visual demands of working at a computer are greater than those required for standard office work, such as reading printed documents. The human eye is not built to stare at a computer screen. To process and focus comfortably, your eyes need sharp edges like those found on paper and ink. Accommodation is the eye system that focuses on lenses. Pixels are tiny dots made up of pixels. Your eye can’t focus on tiny, round pixels so you need to adjust your focus in order to keep images sharp. Even if you increase the number of pixels per sq. or speed up the refresh rate, the eyes cannot maintain a relaxed focus on the computer screen. Redrawing the monitor constantly can cause repetitive stress to the eyes and eventually fatigue.
Bifocals do not work well at the computer. The bifocal actually makes the problem worse because the reading portion of the Bifocal is intended for a shorter distance than the computer screen and a lower angle. Lower back and neck problems can be caused by the tendency to raise the chin and get closer to the screen. Progressive lenses, eyeglasses that do not have bifocal lines, suffer from the same problems. The area for intermediate computer vision lies in the lower half of progressive lenses and the viewing area is very limited.
CVS can cause problems at work and at home if you spend more than two hours at the computer. Employers who are smart recognize the benefits of computer-friendly eyewear can increase their work productivity. Computer Vision Syndrome can be eliminated by visiting your eye doctor. Computer glasses can be used to maintain a natural head position and neck with the clip-on ergonomically designed computer reading glasses.
You have the option to have computer glasses made specifically for you, or you can convert any eyeglasses you already own that are used only for reading and distance into computer glasses. A clip-on lens that allows you to view your computer monitor is an affordable and easy way to do this. You can instantly feel the difference by attaching the lens to your existing general wear eyeglasses. You can save your eyes from the nagging eye strain and increase your productivity at work. You will feel much better at work with a pair of computer glasses or the clip-on computer reading glasses. They will reduce your neck pain, back discomfort, and eyestrain.
