The phone tired of the computer is the main complaint related to the health office in the US, with about 60 million Americans suffering from visual computer fatigue according to the American Optometric Association. The use of computers at work as in the home continues to grow exponentially. The use of computers is associated with a number of visual and physical symptoms experienced by 50% -90% of all computer users. So if you have experienced fatigue, headaches, eye damage, blurred vision, dry or irregular eyes and neck pain or a computer, it is possible that you are suffering only some symptoms called computer vision syndrome (CVS). Resolving CVS symptoms requires a visit to your ophthalmologist to determine if you need corrective lenses while working on your computer, especially if your computer uses two or more hours per day. The outcome of computer vision problems is explained in more detail with a simplified description of how the eye and brain process visual information.
Working on a computer is visually more demanding than doing other standard office jobs, such as reading printed materials. Human vision is not designed to look at a computer screen. His eyes would require constant vivid striped images, as the characters found ink and paper, to process and concentrate comfortably. The eye lens focusing system is called accommodation. Computer images are composed of small roundabouts, known as the name of pixels. Because your eye can not focus on small round pixels, you should always keep in mind the reorientation or to keep them sharp images. The eyes can not maintain a constant relaxed attention on the computer screen, even if the number of pixels per square inch or more has increased in the refresh rate of the computer. The monitor is constantly “redesigned”, which ultimately leads to repetitive strain of eye muscles and fatigue.
Bifocal lenses are not useful to the computer. In fact, bifocal increases the problem because the reading portion of the bifocal is designed for a shorter distance than a computer and a much lower viewing angle screen. The tendency to lift the chin and get closer to the screen leads to low back and neck problems. Progressive lenses (bifocal glasses, without lines) have the same weaknesses as the intermediate computer vision area is in the lower half of the vessels and the viewing area is limited.
If you spend two hours or more on the computer, CVS can be a real problem at home or at work. Academic employers are beginning to recognize that increased production work can be achieved with glasses designed for computer use. Visit your doctor who is willing to help you eliminate the problems of computer vision syndrome with a pair of glasses equipment. You can enjoy a natural position of the head and neck with computer goggles or new ergonomic reading glasses designed for the computer.
