THE EYES HAVE IT

Computer users can dramatically reduce eyestrain by using indirect lighting, according to a new study from Cornell University.

The study compared conventional computer-area overhead fluorescent lighting with indirect, bounced fluorescent lighting. Workers who used conventional overhead lighting had 25 percent more complaints of eyestrain.

The study found 71 percent of those using the indirect lighting and 74 percent of those using conventional lighting preferred the indirect lighting. The most popular form of lighting consisted of lensed indirect fluorescent lights that focused light toward the ceiling.
