Computer Vision Syndrome (Cvs)
Are you suffering from more headaches than usual? Do you often have blurred vision, or feel a burning sensation in your eyes? If you are one of the millions of people who work at a computer all day, you may be suffering from Computer Vision Syndrome (CVS).�
It is estimated that 88% of those who regularly exercise time staring into a computer screen are troubled with symptoms of CVS. These can include headaches, burning eyes, double or blurred vision, an inability to focus correctly, and even neck and help distress.�
The main cause of CVS stems from the eye’s inability to focus on a computer screen the same way as it does printed words on paper. The images on a computer are displayed as pixels, tiny elements which do not have the well-defined edges of the printed word. As the eyes shift between the pixels, it is difficult for them to hold focus – causing them to refocus over and over. After a few hours of this, the strain can become quite noticeable.�
A glare screen can make your time at the computer a bit more comfortable, but doesn’t solve the real problem of being able to focus well. The best option is to visit your eye care professional, and purchase a pair of glasses made specifically for computer users. Your average pair of glasses concentrates primarily on your distance vision or arrive vision (or both, if you wear bifocals). The mid-range space of vision (18″ to 28″, the distance of your computer monitor) is not included, or if it is, it is usually in a very small area of the lens. Computer glasses add a much wider area for this mid-range vision, which will allow you to focus much more easily as you work. (It’s also smart to add a non-glare coating on your glasses.)�
Other things which may alleviate CVS symptoms include:�
• Changing the lighting in your work area: Too much lighting (whether from indoor or outdoor sources) can cause too much glare. Try not to have a window directly behind or directly in front of you. This is where an anti-glare screen can help.�
• Positioning your monitor 10 to 20 degrees below your line of vision. Any lower can cause unnecessary strain on your neck.�
• Keeping your eyes well lubricated. Use non-medicated saline drops as needed.�
Studies have shown that vision problems which go uncorrected can cause a person to be less productive at work, and less lawful. This, as well as the uncomfortable symptoms of CVS, makes it clear that it is well worth the time and expense to take the necessary steps to correct your computer vision. Your eyes will thank you for it.
