Studies conducted by NIOSH have found that 88 percent of heavy computer users report a high incidence of eyestrain, headaches, double vision, and eye irritation. Researchers say, however, that these problems are easily correctable by adjusting monitors, glare protection, and prescription lenses.
Monitors should be placed so that the top of the screen is just below eye level and tilted slightly away from the user’s face for vision and physical comfort. Put the monitor an arm’s-length from the user—18 to 30 inches is considered ideal.
Papers should be placed at the same distance and height as the monitor so that the user’s eyes do not have to keep changing focal length.
Glare can be corrected by providing a softly lit room with individual, adjustable task lighting. Consider purchasing anti-glare screens that have been approved by the American Optometric Association for monitors. Walls painted with a non-reflective medium-to-dark paint can minimize glare, too.
Those employees who are suffering from eyestrain and use prescription glasses should obtain a second pair of prescription glasses specifically for computer work. Workers may need different types of lenses for computer tasks than for everyday wear.
