Computer Vision Syndrome
As the use of computers become more common each and every day, with some people spending literally hours staring at the computer monitor, it is easy to see how we can begin to have trouble with our eyes. Computer Vision Syndrome, also known as CVS, is estimated to affect around fifty-four million adults and children within the United States.
What happens is this, as we spend more hours looking at the computer screen (typically two or more hours) the eyes begin to suffer. The brain and eyes react in a much different manner when looking at characters upon a computer screen, than when looking at printed items on a piece of paper. The characters on a piece of paper have specific character, edges, and contrast. Those upon a computer screen, do not. They have bright centers and towards the edges, the intensity diminishes. This creates a problem within our eyes because the eyes are not able to focus on the characters.
As we attempt to focus on what we are seeing, our eyes tend to move involuntarily to an RPA or a resting point of accommodation, creating the need for eyes to try to refocus again. All of this work on the part of our eyes creates burning and fatigue of the eyes the longer we look at the computer screen.
There are symptoms that come along with Computer Vision Syndrome, usually after spending around two hours or more on the computer, more specifically the screen, you will undoubtedly begin to experience at least some of these symptoms such as pain in the shoulder or neck, blurry or double vision, tired or burning eyes, inability to keep focus, or even headaches. Within a child, if they use the computer for prolonged periods of time, their eyes will become stressed and ultimately have a great impact on the development of their vision.
People with CVS or Computer Vision Syndrome, often have a hard time with maintain productivity at work or school. When you suffer from CVS you often have the inability to remain focused and may suffer from some of the symptoms which could lead to loss of comfort, accuracy may suffer, and productivity loss all at the same time.
Overall, Computer Vision Syndrome is not a pleasant thing and should not be taken lightly. In further articles, within the CVS series, we will discuss what you can do to eliminate the problems and provide you with solutions to avoid computer vision syndrome.
