Computer Vision Syndrome Info

These days huge numbers
of people spend long hours looking at a pc
screen and therefore are likely to
acquire computer vision
syndrome if protective steps
aren’t taken to prevent it.

The signs of Computer Vision Syndrome
Studies
have shown that if you spend more than a couple of hours
each day looking at a computer display, it’s likely you can experience some degree of computer vision syndrome. Computer Vision Syndrome
signs and symptoms include:
Shoulder and
neck soreness, Severe headaches, and Loss of focus.

What causes Computer Vision Syndrome?
Computer
eyesight strain along with Computer Vision Syndrome are caused by our eyes
responding differently to material on the
screen compared to the way they do to printed characters. Your eyes
can focus easily on
printed material that has dense
black characters along with
well-defined edges, nevertheless the characters
on the computer screen don’t have the same level of contrast
and/or definition.

Terms as well as other objects on a
monitor are created
with tiny dots of light or pixels, which can be bright at the centre but diminish in
intensity toward the edges, making
it harder for the eyes
to preserve focus on these kind of objects. The eyes drift
instead to some diminished level of
focusing known as the “resting point of
accommodation” or RPA.

Since your
eyes involuntarily move, they strain in order to regain focus on the screen.
This particular continuous
movement of the eyes’ concentrating muscles
generates fatigue and
also eye pressure that
typically occurs in
the course of and right after computer use.

Treatments for Computer Vision Syndrome

To lessen the risk of computer eye
strain and computer vision syndrome, you should see a great optometrist who specialises in
pc vision
treatment. The
ensuing exam includes tests to detect any vision problems that
could give rise to Computer Vision
Syndrome. Depending on the outcome of the exam,
your skills doctor may
well prescribe laptop or computer
eyeglasses to boost your
comfort.

Computer
spectacles will eliminate the constant refocusing
pressure that your sight undergo
when viewing the
monitor. And it has proved clinically which
having the correct prescription
computer eyeglasses
raises productivity and
also accuracy.

Does Everyone with Computer
Vision Syndrome Have to have Computer
Glasses?

Clinical tests suggest that most pc users encounter some amount
of eye soreness, so it’s
sensible to assume that
people doing work more than two hours daily in front of a
computer screen would reap the benefits of computer
eye wear.

Do I Have
to have Computer Eyewear If I Do Not
Have Computer Vision Syndrome Symptoms?
As outlined by a study in the University of Alabama’s Birmingham
College of Optometry, computer
users who do not experience Computer Vision Syndrome might also benefit from computer eyewear. The study indicated that even if you do not
observe eye tension or other
signs and symptoms of Computer Vision Syndrome,
it’s recommended that you receive an eye
examination from a computer vision
consultant if you spend a lot
of time each day in front of your personal computer.

  1. As I have read, Computer Vision Syndrome does not leave any permanent damage to the eyes. Is this really true?Also, does the amount of heal time needed for the eyes to rest relate to the amount of time of prolonged use on the computer, or is the amount of rest time the same for any amount of computer use?Any tips on alleviating blurred vision caused by CVS.Thanks

  2. With the way I sit in front of the computer I really need to go check this out. My eyes do strain and I don’t want to have problems later. Can any eye Doctor check this out?

  3. I think CRT monitors, especially with a lower refresh rate is very bad for your eyes if using for extended periods. I would recommend all offices to switch to LCD/LED monitors as they are really much more pleasing to the eye and can save a lot of space on the desks also.

  4. I used to use a CRT monitor that was 15″ inch and it did seem to hurt my eyes but it was pretty small. When I later used a 17″ CRT monitor I was experiencing some significant eye strain. I use an LCD now.

  5. Ya know I have had a spasm in my left lower eye for 5 days now and I am wondering if me being in front of the computer so much is making it happen or if it is something like stress. This article has made me think. I hope it isn’t my pc that is causing this.

  6. Robert, I remember when I had bought my first 17″ CRT some years ago, I found 85 Hz to be the most comfortable refresh rate for its optimal resolution. Even down to 75 Hz is safe but 60 Hz is quite strenuous on the eyes but is usually the default setting unfortunately.
