 Do
hours of computer work leave you with tired, dry eyes, and blurry
vision? Perhaps even headaches or neck aches?
Computer Vision Syndrome (CVS) has become
quite common as our offices and homes have become less paper-oriented and more computer-centric.
Computer glasses are designed specifically to provide relief from these
symptoms. What
are "computer glasses"?
First, they are not reading
glasses. Reading glasses are optimized for the distance to a
book in your hand and a slightly downward direction. Similarly, computer glasses are
designed for the
greater distance from your eyes to your computer monitor and
a forward viewing direction.
Trying to use reading glasses for computer work can lead to
neck strain, because you may have to lean in closer to get
the clearest vision, and you may have to tip your head up to
view the screen through the lower part of eyeglasses
normally used for reading.
Computer glasses also have anti-reflective coatings
to reduce glare and reflections that cause eye strain.
Multi-purpose glasses
Wearers of progressive lenses,
also known as no-line bifocals, can also benefit from a
separate pair of computer glasses. Progressive lenses
are usually designed for reading through the lower part of
the lens and for long- distance
viewing, like driving, through the upper part of the lens.
The computer screen sits at an intermediate distance, so
standard progressive lenses are not well suited for
prolonged computer use.
Does your work day involve an
even mix of reading and computer work? Occupational
progressive lenses can be made with a lower reading window
and an upper intermediate window, such that a single pair of
glasses can be used for both reading and computer work. Some
even have a third window in the upper part of the lens for
distance viewing such that a glance up will tell you if that
is your boss approaching.
Clearly there are many options
to chose from and many factors to consider. Your
optician can guide you through the process of selecting the
correct features for your eyeglasses to meet your visual
needs.
Other ways to find relief from
CVS Whether you need computer glasses or not,
hours of screen time can strain your eyes, leaving them feeling dry,
tired, and difficult to focus. You can find some relief by
taking routine eye breaks, looking off into the distance, away from your
monitor and blinking slowly to lubricate your eyes. Another
technique: try warming your hands by rubbing them together, then cupping
them over your eyes, and blinking slowly for half a minute in the dark.
Your desk arrangement is also an important factor to consider.
Headaches and neck aches can be the result of leaning in to compensate
for visual difficulties, but independent of how well you can see the
screen, your chair, keyboard and monitor all must be positioned
correctly to avoid straining your frame. The American Optometric
Association has an excellent article describing
workstation setup
for comfortable computer use.
