Once scoffed at as mere in­convenience, computer-related eyestrain is gaining new atten­tion as a high-tech affliction undermining employee health and productivity. Dubbed computer-vision syndrome, the malady can mean dry eyes, blurry vision and headaches. Concern over the problem is escalating as computer use becomes more prevalent.

Experts remain divided on long-term effects, because computer use has only been widespread for the past 10 years. Some say prolonged use can trigger nearsightedness. While many symptoms disappear after a few hours, they can still hurt productivity.

  • Health care and glasses inked to computer use costs companies and employers nearly $2 billion a year, based on data released through the American Optometric Associa­ion.
  • The National Institute for Occupational Safety and Health found 75% of video screen users reported occa­sional aching or burning eyes at work.
  • About 12 million eye ex­ams are given annually be­cause of computer-related problems, research indicates.

“I spend more time with my computer than my wife,” jokes Bill Sampson, 52, an eyestrain sufferer who works for a chem­ical firm in Chickamauga, Ga. “I would get headaches. It was like being out on a snowy day when it’s bright and you don’t have sunglasses.”

Problems are caused in part because people blink less when gazing at computer screens, which leads to dry eyes. Glare and reflection from windows of office lights trigger strain. And reading from a computer screen is more difficult than from a printed page, where letters have higher resolution. At the same time, more employees are expected to have the problem because about 75% of all jobs are expected to involve computers by next year.

“I’m on e-mail so much,” says Victoria Desidero, 38, marketing vice president for Merlot Communications in Be­thel, Conn. “I have to break up the time because I start seeing double. I feel like my eyes are getting worse.” Says Anjeanette Steele, 25, who handles public relations for Intervu, an Internet video delivery firm in San Diego: “I live on the computer. I’ll be working and then look up and it will be blurry.”

Experts suggest simple changes such as minimizing overhead light and glare, sitting at least 20 inches from a com­puter screen, wiping away dust and fingerprints, using an anti-reflection screen and taking frequent breaks.
