The Newest Work Hazard For Computer Users: CVS

Millions of Americans go to work every day to sit at a computer for 8 or more hours, seven days a week. While office work is hardly considered to be a "dangerous" job, several years ago, doctors began to notice that certain afflictions are becoming increasingly common among those who use computers all day long.

First, the medical community became aware of CTS (Carpal Tunnel Syndrome), a painful and sometimes debilitating inflammation in the wrist, arms, and hands. In response to the increased number of office workers being diagnosed with CTS, computer furniture manufacturers began to develop ergonomically correct keyboards and keyboard trays, as well as computer chairs that offer more comfortable seating for computer use. Now, many employers provide ergonomically correct workstations for their office staff and CTS is on the decline.

Unfortunately, a new hazard has now taken the place of CTS. It's called CVS (Computer Vision Syndrome), and is caused by prolonged visual exposure to a computer screen. CVS has, in the past two years, become the number one health complaint of office employees.

Like CTS, Computer Vision Syndrome is also preventable. There are a few things you can do to reduce the sensitivity and eye strain associated with computer work. According to optometrist Dr. Larry K. Wan, there are five key ways to reduce the effects of CVS.

Dr. Wan suggests getting regular eye exams, which means (according to NIOSHthe National Institute of Occupational Safety and Health) once a year. While many contact-lens wearers are required to get eye exams each year to renew their lens prescription, it's important for those who don't wear contacts as well. Tracking the health of your eyes will allow your optometrist to identify whether or not you're experiencing a deterioration of vision due to CVS.

Dr. Wan also contends that proper lighting is important, citing that eyestrain can be caused by excessive lighting either coming in through a window, or from interior lighting itself. Dim your lights when using a computer.

Glare is another factor that Dr. Wan claims can cause CVS. In addition to adding an anti-reflective coating to your eyeglasses, glare can be prevented by anti-glare screens attached to your monitor, or by using an LCD monitor arm. LCD monitor arms actually allow you to tilt or slide your monitor at the touch of a finger, eliminating strain as the light in the room changes. We found affordable, high-quality LCD monitors online at Versa Products, Inc.

Adjusting the brightness of your computer screen can also help. Optimize for comfort which may mean either reducing or increasing the brightness. Find one that feels comfortable to your eyes.

Interestingly, Dr. Wan also tells his patients to blink more often. When staring at a computer screen, we tend to blink less than we normally doa process which keeps the eyes lubricated and comfortable. Make a point of blinking more often and every half hour, blink about ten times in a row, slowly. This will help reduce the effects of CVS as well.
