Millions of individuals suffer from 'computer vision syndrome'
Do you feel like your eyes tire more easily while working on the computer?
Do you experience a sandy or gritty sensation? Neck or back pain? What
does this have to do with vision?
Using a computer places several different demands on our eyes and visual
system. Millions of individuals suffer from 'computer vision syndrome', a
term given to many eye/vision symptoms associated with computer use.
The proper ergonomic setup is important, especially if you wear progressive
addition (no-line trifocal) lenses. The best scenario is where your eye
level, in a straight-ahead position, is at or even an inch or two above the
top of the monitor. This allows clear vision through slight downgaze,
without the need to adjust your head and neck accordingly.
The most common
problem is the monitor being too high, in which case it is necessary to have
an adjustable chair or lower the screen if possible. You should not have to
tilt your head to see the screen clearly.
Of course, certain work
environments may prevent you from achieving the ideal placement of the
monitor. If so, it may be necessary to have your eye doctor write a
customized glasses prescription based on your exact situation.
The 'pixellated' nature of computer text does not allow sharp contrast
between the edge of "text" and "no text" (as in printed text), and this
phenomenon has been shown to tire our eyes more than if we had looked at
printed text for an equal amount of time. Although there is no cure for
this, the best treatment is to use a good quality monitor and to take breaks
a few times per hour. Let your eyes relax as you focus at distant objects,
such as out a window, for a minute or two.
Some individuals prefer to use an anti-glare filter. Most find that glare
is reduced if there is not a window immediately past the monitor or behind
Studies show that our blink rate reduces significantly when using a
computer. This can lead to dry eye sensation (sandy, gritty feeling) or
exacerbate a pre-existing dry eye condition. Many individuals find that a
forced air heating or cooling register in the immediate vicinity can make
the problem even worse. The best treatment here is to not have air blowing
directly at your workstation, drink 8 glasses of water daily, consciously
remember to blink, and see your eye doctor if you still have symptoms.
These are just a few of the ways that computer use can interfere with
maintaining clear, comfortable vision.
