Possibly. A recent study of 12,000 people revealed that one out of
every three adult Americans is nearsighted -- that is, they have
difficulty seeing things clearly from a distance. This percentage is
“substantially higher than reported by earlier studies,” notes lead
researcher Susan Vitale, Ph.D., of the National Eye Institute at the
National Institutes of Health. What’s more, Vitale and her colleagues
found that about half of Americans age 20 or older have “refractive
error,” or problems with focus that include nearsightedness,
farsightedness and astigmatism.
What’s causing this increase in blurry vision? More research is
needed to know for sure, but increased computer use could be one of the
culprits. “There are a lot of factors to consider,” says Vitale. Are
people working more? Are there differences in lighting conditions? Is
less time being spent outside? There are also genetic influences that
can increase the likelihood that you’ll need glasses, she adds.
One thing experts do know, however, is that prolonged computer use
causes eye strain. To avoid eye discomfort when using a computer,
experts recommend working in a well-lit area, taking frequent breaks
and using an antiglare screen whenever possible.
