Computers. To most of us, it’s hard to remember how we ever got our job done without them. More than 143 million Americans use a computer at work every day. And if you spend more than two hours a day in front of a computer, you could be among the estimated 125 million people suffering from Computer Vision Syndrome or CVS.
CVS is caused by the eye constantly focusing and re-focusing on the characters on a computer screen. These characters don’t have the contrast or well-defined edges like printed words and the eyes’ focus cannot remain fixed. As a result, you may experience symptoms that include headaches, loss of focus, burning or tired eyes, blurred vision and neck or shoulder pain. Making some changes in how you work at a computer can help reduce eye strain.
• Eliminate exterior light from entering your workspace by closing drapes or blinds. Reduce interior lighting. Position your monitor so that windows are to the side of it-not in front or behind.
• Minimize glare by installing a glare shield on your computer and having an anti-reflective coating applied to your lenses.
• Follow the “20-20-20 Rule,” every 20 minutes, look away from the computer screen and focus on an object 20 feet away for 20 seconds. Also, take a 10-minute break away from the computer every hour.
• Adjust your monitor so it is positioned at or below eye level and adjust your office chair so your legs can fit comfortably under the desk.
These changes, while helpful, do not address the underlying visual problem of CVS.
A comprehensive eye exam, including questions about a person’s computer use habits can often be the first step in remedying CVS. If results of the examination determine that vision correction for computer use is required, computer lenses can be prescribed. These lenses are designed to improve your vision in the 18-inch to 28-inch range, the optimal distance between your eyes and the monitor.
While prolonged computer use will not damage vision, it can make you uncomfortable and decrease your productivity. If you think you may have Computer Vision Syndrome, call our office and make an appointment today.
