Big Problem, Small Cause

By Karlen McLean, ABOC, NCLC

Recent studies have shown that the majority of people who work at computers experience some eye or vision problems, with the level of discomfort increasing with the amount of computer use.

Additionally, increased use of smaller portable gadgets like laptops, PDAs, and cell phones for text messaging and website access may also be contributing factors to visual fatigue and discomfort experienced by millions.

"The unique characteristics and high visual demands of computer work and play make many individuals susceptible to the development of eye and vision-related problems," notes Jeffrey Anshel, OD, the author of Visual Ergonomics in the Workplace.

"With the proliferation of portable electronic devices such as laptops, Palm Pilots, and video games, it's no surprise that ECPs are seeing more patients who complain of ocular discomfort," he adds.

Staring at big or small screens can lead to a variety of ocular ailments, including headaches, eyestrain, blurred vision, dry and irritated eyes, neck and/or backache, and sensitivity to light.

"Eye stress and strain may be caused by a combination of poor environmental condition, individual visual problems, and improper viewing habits," Anshel says.

"[These include] glare, improper workstation set up, dirty screens, and poor lighting and viewing angles."

Uncorrected or under-corrected vision problems can be major contributing factors to computer-related eye stress, which affects visual performance and comfort.

A new online tool that ECPs can use when working with patients who complain about computer-related vision problems is an interactive quiz from Vistakon available online at www.computerquiz.jnjvision.com.

The quiz helps educate consumers about some of the most common computer-related vision problems and how to prevent or reduce the development of these problems. EB
