Eyestrain and
Headaches
Headaches triggered by eyestrain are becoming an everyday
thing for many people whose jobs require spending a great deal
of time in front of the computer. Eyestrain headaches can also
be brought on by playing too many video games or watching
television for too long. Eyestrain headaches are more common in
people who need to wear eyeglasses or contact lenses or those
whose current eyeglass prescription needs updating.
The reason those who do not have 20/20 vision have headaches
more often than those who do have perfect vision is because the
muscles controlling the eyes have to work harder to press the
eyeball into a shape that allows them to see clearly. For
instance, if you often catch yourself squinting in order to
see, this is one way your eye muscles work to readjust your
eyeballs for better vision. If you have to squint for extended
periods of time, this will tire and weaken the muscles in your
eyes. The result is that you will eventually get an eyestrain
headache.
Computer Vision Syndrome
Computer Vision
Syndrome, or CVS, was appropriately named for an eye
problem which has become common with so many people spending so
many hours in front of a computer screen. CVS has also been
called a "pixel headache."
The reason more headaches are reported by computer users
than those who do paperwork lies in the way the letters on the
computer screen are formed. These letters are made up of
hundreds of tiny dots or pixels. Our eyes must work overtime to
fill in the gaps to make theses dots appear as smooth, whole
letters. This extra work can result in eyestrain headaches.
Reading a computer screen does not cause permanent damaging to
eyes. Your headache will go away after a short spell away from
the computer screen.
In addition to making the eyes work harder, another reason
computer users may suffer more headaches is because they often
sit with incorrect posture. This bad posture puts strain on the
muscles in the back and neck which may also contribute to the
occurrence of headaches.
Ways to Prevent Computer Headaches
• Take occasional breaks from your computer work to get up
and walk around. Use this time to get rid of any built-up
tension in your muscles by massaging your face, neck and
head.
• Adjust the contrast on your computer monitor so that the
screen is not too bright or too dim. It is also a good idea to
us a glare shield on your monitor to make it easier to
view.
• Don’t sit too close to the computer monitor.
• Make sure that there is proper lighting while you do your
computer work.
Checking Your Posture
In order to cut down on computer headaches, is it a good
idea to make sure you are sitting properly. First, make sure
your computer monitor is at eye level. Next, check out your
chair. If your computer chair is at the correct height, your
forearms will rest comfortably on your desk as you use the
keyboard. In addition, it is a good idea not to store junk
under your desk. Get rid of all this stuff so you can stretch
out your legs occasionally.
Adequate Lighting
You may wonder what constitutes adequate lighting. Adequate
lighting will give you enough light to easily view what you are
working on. This means that you should not watch television or
work on the computer with no lights on. Without proper light,
your eyes will have to work extra hard to adjust themselves for
better vision. If you like to watch TV or work on the computer
with the lights turned off and you are prone to getting
headaches, this inadequate lighting can actually make things a
lot worse for you.
Identifying Eyestrain
There are several telltale symptoms of eyestrain. If
you suffer some or all of the following symptoms, you might
have eyestrain.
• A headache after doing work on the computer
• A headache after watching TV for an extended period
• A headache after reading a book
• A burning sensation in the eyes
• Eyes that feel tight, itchy or irritated
• General tiredness
• Periods of blurry or fuzzy vision
• Periods of dizziness
If you suffer any of these above symptoms, you should make
an appointment with your doctor or ophthalmologist as soon as
possible. He can fit you with glasses that will head decrease
eyestrain, or can suggest other means to cut down on the number
of headaches you suffer.
