I've been staring at computer screens for 12 years just fine, oftenHi
many hours a day, until about a year ago. Since then, after about 4
minutes of looking at the screen, my eyes feel like...well, they feel
like when you look out from the extreme corners of your eyes for a
long period of time, only this happens when I'm looking straight at
the screen. My veins in my eyes become quite red and noticeable. My
eyes will remain like this (both hurting and red) for many hours after
I'm done with the computer.
I've tried using different monitors: a CRT and an LCD (both are
adjusted properly regarding contrast and brightness) and adjusted the
height of the screens. I have taken breaks for many days at a time
where I wouldn't look at a computer screen, only to find that when I
came back my eyes would still hurt after a few minutes. I've even worn
sunglasses while using the computer to make sure it wasn't the
brightness. I saw my optometrist a week ago for an eye exam, and he
said everything looked normal. Quite frankly, I don't know what to do.
If I don't get this fixed I will definitely have to change my career,
as I simply can't bare looking at a computer screen anymore. :(
One more for you.
Computer vision syndrome is a common complaint of office workers more
prevalent in the last years due to the widespread use of computers and
video display terminals (VDT?s). Common symptoms include sore and
irritated eyes, dry eyes, headaches and blurry vision. But
fortunately, there are many ways to enhance your work environment to
help prevent computer vision syndrome.
Computer images are made up of tiny dots that do not give a clear
image so your eyes are forced to focus and re-focus continually. This
is one of the main reasons that computer work is so straining on the
eyes.
Ensure that you are working with a good quality computer screen and
make sure the resolution is set high as high as possible for your
work.
Force yourself to blink more often than usual and use mild lubricating
drops if you experience dry eyes. Take ?eye breaks ? at least every 20
minutes by looking away from the screen and focusing on something in
the distance for at least 20 seconds.
Ensure that the lighting at your workstation is appropriate for
working at the computer. Make sure there are no bright lights shining
into your eyes or your computer screen. Don?t make the mistake of
having too much light. Too many light sources within one space will
distract your eyes from the screen and cause glare on your screen.
Make sure that neither you nor your screen are facing a window.
If glare is a problem try changing the position of your desk. Hang
pictures or temporary walls to eliminate other sources of light.
Reflections can be very straining for the eyes. Two types of
reflections exist, diffuse and blocking. Diffuse reflections are those
reflections caused by a reduction in the contrast of text presented on
the screen. Low contrast makes it difficult for the eyes to focus.
Blocking reflections block out parts of the screen, which forces you
to move in order to see the object.
Reflections can be prevented by either using anti-reflection filters
on the screen or by eliminating the reflection source. If too much
light is coming in through the window, used blinds or curtains. Always
try out different positions. It is often the case that computer users
are not even aware of the discomfort they are experiencing because
they have become so ?used to it?.
The positioning of the monitor in respect to your posture can make all
the difference in the world. The computer screen should be at an angle
of 0 to 20 degrees from a straight visual line looking down slightly.
And keep your screen 50-60 cm away from your face.
Computer glasses
If you are over 40 chances are that you already use glasses. And if
you already wear glasses or contact lenses it is not guaranteed that
you might not need separate glasses for working at the computer
screen. Those who wear bifocals or trifocals are often forced to move
their heads so that they can see the screen through the right section
of the glasses. Glasses and contacts usually correct near and far
vision and sometimes both but rarely do they correct the mid-range
needed for a computer screen. Even if you wear contact lenses you may
still benefit from computer glasses.
Computer glasses provide a wide field of view so that users can
clearly read their screen and printed material that are at different
distances and correct the distance held looking at a computer screen.
Tinted glasses are also available to help prevent glare from computer
screens and surplus lighting (not needed but cannot be switched off).
If you are experiencing eye problems while working at a computer
screen it is a good idea to see your eyecare specialist for a thorough
eye exam and ask him/her for their recommendations.
Summary of Steps for Preventing CVS
Use good quality monitor
Set resolution high
Make an effort to blink your eyes more often
Ensure proper lighting at your workstation
Don?t have you or screen facing a window
Eliminate any sources of glare in the office
Angle your computer slightly below eye level
Position your monitor 50 to 60 cm away from your eyes
See your eyecare specialist for an eye checkup to determine if you
need computer glasses.
