healthier while working.

Do you strain to look at the screen? Does it compete with the reflections
of the lights? Is the light coming through the windows so bright that you
squint to see the screen? Is there dust on the monitor screen? As the
text looks fuzzy, we unknowingly begin to squint or strain while looking
at the monitor. Protect your eyes and make sure you can SEE.


Clean the screen weekly to improve clarity since the screens static
electricity makes it is a superb dust collector. If you wear glasses do
not forget to clean them.

Check and reduce the reflections on the screen. Turn the monitor off to
observe the reflections. If there are light source reflections visible in
the darkened screen explore some of the following options:

  • Place the monitor at a 90 degree angle to the light source instead of
    behind and/or above you.

  • Install an anti-reflection filter on the screen.
  • Buy a monitor with anti-reflection coating when replacing equipment.
  • Tape a cardboard tablet backing to the side or top of the monitor to
    create shade.

  • Adjust window shades throughout the day to allow for the changing angle
    of the sun.

Remember, clarity of vision also depends upon your ability to focus your
eyes to see the screen. For many people older than 40, special computer
glasses may significantly reduce eyestrain.

Finally, do not forget to blink and rest your eyes by looking away from
the monitor to a tree or other green object.
