STUDY SHOWS CVS HAS MAJOR EFECTS ON WORKER PRODUCTIVITY

(Beaverton, OREGON) Computer Vision Syndrome or CVS, whose symptoms may effect as many as 70 percent of all computer users, does not only result in eyestrain, but may significantly decrease worker productivity.

This is according to the preliminary results from a study being conducted at the University of Alabama-Birmingham School of Optometry, which drew the following conclusions:

A direct correlation exists between the correct Rx and productivity. This is particularly evident with more complex computer tasks (e.g. data entry). There is a direct correlation between the time the user takes to perform a task and the correct Rx. Computer users with moderately miscorrected Rx's may not be able to tell the difference in their vision comfort, but their performance on a specific task can be significantly decreased, as much as 40 percent. Eye doctors cannot "guess" the correct Rx. A moderate miscorrection (1.0 D) can be as significant as a large miscorrection (2.0 D).

The study examined workers ages 24 to 51 years of age in the laboratory. It used the PRIO Vision Tester, which simulates the pixels on a computer monitor, to provide the correct Rx for computer-specific eyewear.

Background
Research has long shown that the visual environment of a computer varies from the printed word. Comprised of pixels or tiny dots, the computer screen is difficult for the eye to focus on. Less definition of these images causes the focus to drift, resulting in a repetitive focusing effort for the eye muscles (similar to any musculoskeletal injury that results from overuse). Workstation design (ergonomic) problems can exacerbate the situation.

The hypothesis of the study, borne out by this pilot data, was that computer vision difficulties—eyestrain, headaches, and blurred vision—present a drag on the typical worker's efficiency on the job. This includes a reduction in work accuracy and a decrease in task volume (i.e. productivity).

Study Results
"Our preliminary data strongly suggests that improving the visual status of workers using computers results in greater productivity in the workplace, as well as improved visual comfort," said Kent Daum, O.D., Ph.D, the study's chief investigator. "Although numerous anecdotal studies have suggested that substantial productivity gains occur when optimal vision care is provided, our study uses a double-blind protocol to prove that investing in optimal computer eyewear for employees results in a significant cost-benefit ratio."

The cost-half of the equation is determined by calculating the average cost of the vision examination and eyewear. The benefit is measured by taking the value of the net change in productivity for the average of the workers over a one-year period. The ratio is realized by dividing the cost by the benefits likely to accrue over a one-year period.

For example, a computer worker is provided with a vision examination and pair of computer glasses at a cost of $230 ($80 visual examination, $150 for frames and lenses). If the average productivity of the worker is 100 claims per day and the worker earns $125 per day, then each claim processed costs $1.25. If the change in productivity is five additional claims per day (5% increase in productivity) for a year's period (250 days), then a cost benefit can be calculated at 5% or $6.25 per day. This would equal a benefit of $1,593 over the course of a year, a positive result based on an investment of $230, or a ratio of about 7:1. Simply put, for every $1 invested in the computer vision care of its workers, the employer would realize $7!

"The preliminary results demonstrate that computer-related vision problems have a dramatic impact on productivity—regardless of job description," said Jon Torrey, president of PRIO, a leader in the computer vision care industry and sponsor of the study. "A computer eye exam should be an employer's first line of defense against decreased productivity and increased workers' comp claims. Computer eyewear is extremely cost effective. And, it is good for business."

Several companies in the U.S. already acknowledge the benefits of providing computer-using employees with computer eyewear. These companies understand that a minor investment in computer eyewear can increase productivity and decrease worker's compensation claims, which average over $9,000 per claim.

One such company is Medtronic, a major medical product manufacturer based in Minneapolis, that has taken the lead by making computer eyewear available to all employees diagnosed with CVS by a PRIO-Provider eye doctor. In addition, several states have established regulations and statutes that govern computer vision care for workers.
