PROBLEM AND ITS BACKGROUND
Vision is our most precious sense. Our eyes are in constant use every waking minute of every day. The way we use our eyes can determine how well we work throughout our lifetime. Over eighty percent of our learning is mediated through our eyes, indicating the important role our vision plays in our daily activities. Vision disturbance is a silent enemy that only appears after a long period of continued stress. Many people in today’s world experience a number of discomforts in relation to spending too much time in front of a computer. These discomforts are especially common for because computer technology is used for most of the classes taught. Many students are unaware of the damage that they are doing to themselves by staring at computer screens for extended periods of time. If many of us were asked what one thing has had the greatest impact on our lives in modern times, we would likely say the computer. Over the past twenty years or so, computers have gone from being monstrous curiosities taking up the entire space in large rooms, to relatively small boxes on almost every desk. Along with smaller size and lower prices has come an explosion in the number of computers. The speed and efficiency of the computers has made most businesses and institutions dependent on the technology. As a result, many people spend a large part of their time working with computers. The relatively recent advent of the widespread availability of the Internet has meant that even those individuals who don’t use computers at work likely use them at home to surf on net or to have fun and etc. What this has meant is that many people are spending many hours on the computer at work and then again at home. As a result, there has been a significant increase in the reporting of health problems related to the use of computers. So, with the increasing use of computers, computer related-vision problems are affecting a growing number of individuals. Visual symptoms include: eyestrain, blurred or double vision, headaches, red or irritated eyes, and color perception changes. Other individuals may also experience neck or shoulder tension, general fatigue, or pain in the back, arms, wrists or shoulders. Improper workstation set-up, a fragile eye teaming or eye focusing system, or poor visual hygiene can aggravate these symptoms. Individuals who suffer from computer vision syndrome may find relief through specially designed prescription lenses, filters or vision therapy. If you experience tension, pain, or visual discomfort when using a computer, you may be suffering from a computer related-vision problem. The incidence of eye complaints is likely to increase substantially due to the widespread use of computers. Computer Eyestrain means different things to different people. It can be experienced as burning, tightness, sharp pains, dull pains, watering, blurring, double vision, headaches, and other sensations, depending on the person. It can result in loss of place while reading visual memory loss, agitation at work, and decreased productivity as the goes on. If you have any eye discomfort caused by viewing a monitor, keyboard, paper work while using the computer, or from visually rocking back and forth, you may call it computer eyestrain. The name for eye problems caused by computer use is computer vision syndrome (CVS). CVS is not one specific eye problem. Instead, the term encompasses a whole range of eyestrain and pain experienced by computer users. In addition, working adults aren't the only ones vulnerable to computer vision syndrome. Kids who stare at portable video games or who use computers throughout the day at school also can experience eye problems related to computer use, especially if the lighting and computer position are less than ideal. Vision problems occur frequently among video display terminal (VDT) workers. Most worker health surveys show that the most frequent health related complaints among workers at...
