COMPUTER
USE AND EYES
|
Instead of starring on the
silver screen, or slugging home runs out of Fenway Park, a great number of
people spend the majority of their workday in front of a computer screen. By one
estimate, nearly 90 percent of those people working at a video display terminal
(VDT) experienced some form of vision problem as a result.
How do you tell if your
symptoms are related to your computer use?
VDT-related symptoms occur
some time after you start work. As the workday progresses, your symptoms will
become more acute. What are the symptoms that are related to computer use?
·
Difficulty focusing after working
at a computer, with blurry or double vision
·
Eyestrain or eye fatigue
·
Headaches or backaches
·
Dry and/or irritated eyes
·
Neck stiffness or discomfort
·
After-images when looking away
from the screen
·
Sensitivity to lighting
·
Muscle spasms
Are there environmental
factors that could affect your symptoms?
·
Bright lights in your peripheral
field of vision could add to discomfort or reduced visual performance.
·
Reflected light on your computer
screen can decrease the contrast of screen characters and possibly force you to
assume an awkward position to see around the glare.
·
The location of your screen could
cause awkward positioning.
To determine the cause of
your symptoms, you should visit your eye care professional. Before going to your
appointment, however, take note of the environment in which your symptoms occur
and at what times they are greatest. This will aid your doctor greatly in the
diagnosis.
If computer eyestrain is
the diagnosis, there are simple methods to ease the discomfort:
·
don't focus on a single object
for a prolonged period of time;
·
improve the lighting around your
monitor;
·
blink often;
·
frequently close your eyes, then
look far into the distance (down a hallway or out a window) every 15-20 minutes
to relax them;
·
sit at least 18-28 inches away
from the screen;
·
tilt the monitor slightly below
eye level; and
·
keep your screen dust-free to
minimize visual interference.
