In today’s technologically advanced world, a computer plays an indispensable role at home, and workplace. Spending too much time in front of a computer poses a number of discomforts including headache, eye fatigue, back pain, and blurred vision, to name only a few. These symptoms have been collectively termed Computer Vision Syndrome.
When you look at your computer screen, you are processing information rapidly. The human eye is able to see objects clearly from a distance of 3 to 20 feet without any visual aid; and at this range, your eyes experience no discomfort. On the other hand, when you look at a computer screen just 20 inches away from the eyes, your eyes expand and contract rapidly to compensate for this small distance and thus your eyes get tired. There are various causes of Computer Vision Syndrome including decreased blink rate (66 percent less than normal) while sitting in front of the computer and reading; reflections off your computer make the eyes tired, incorrect positioning of the monitor can make it hard to focus on the screen, and poorly set up workstations can cause pain due to repetitive injury. There are various preventive measures you can take to avoid computer vision syndrome. Try to blink frequently while sitting in front of your computer, take a break after every 15 minutes, reposition your computer, replace the light bulb to a full spectrum light, use a large monitor, as it is easier to see, increase font size, control and adjust the brightness and contrast of the monitor, position your monitor screen 20 to 26 inches away, and use anti-glare eye glasses, besides others.
A majority of people suffering from computer vision syndrome are in their 40s and older. The main reason why this age group of people most suffer is that as they age, their eye muscles get weaker and lose the ability to control accommodation as they shift their view. In addition, people who do not wear appropriate eyeglasses often suffer from computer vision syndrome. There is no treatment as such for computer vision syndrome, but one can definitely avoid these symptoms by taking some preventive measures. For example, one of the easiest ways to treat accommodation problems is to use low plus lenses and anti-glare. Use a comfortable chair and sit straight to avoid back pain. Most people who use computer for longer hours do not take breaks, which is not good. Take small breaks at 15 or 20 minutes interval, and blink frequently – this will help revive eye muscles; and if you face frequent eye problems then see an eye doctor without any delay.
