Tests
have proven that
when working
on a computer,
individuals blink
at less than
half their normal
rate. When you
blink less, your
eyes do not cleanse
and lubricate
themselves sufficiently,
which make them
dry, red, gritty
and irritated
& leads to
CVS.
Moreover,person’s
vision is not
suited for staring
at a computer
screen for many
hours. Computer
screens are made
up of pixels
or tiny dots,
on which the
eye can not lock
focus. The computer
user must therefore
focus and refocus
to keep the images
sharp. This results
in receptive
stress of the
eye muscles.
Additionally,
after prolonged
computer use,
the frequency
of blinking is
decreased, which
causes eyes to
dry out and to
become sore.
As a result,
the ability to
focus diminishes
and vision may
blur, which causes
headaches and
neck pain.
Studies
have demonstrated
that even seemingly
minor distortions
in vision can
cause significant
eyestrain when
working at your
computer. The
clarity of the
image you see
depends on the
clarity of the
image on your
computer screen,
the clarity of
your eyewear,
and the clarity
of the various
media within
the eye through
which the image
must pass. |

Q.How
many people suffer
from eye problems
due to computer
work? |
|
A.
Studies
show that nearly
62 million people
suffer from eye
or vision problems
due to computer
work. A recent
study also found
an increase in
computer-induced
vision problems,

Q.
Who
is at risk for
CVS? |
|

person who spends
approximately
two hours a day
working on a
computer is at
risk for developing
CVS. |
|
Q.
How
can I prevent
CVS? |
|
A.
- Keep
your computer
monitor clean
as it increases
visibility.
- Make
sure your
computer
screen is
20-25 inches
from your
eyes at about
15-20 degrees
below eye
level.
- If
you use a
document
holder, keep
it close
to the screen.
- Dim
overhead
lights and
keep desk
lamps low
and properly
adjusted
so the light
doesn't enter
your eyes
or fall on
screen.
- Every
15 minutes,
focus on
distant objects
to relax
your muscles.
- If
needed, use
an antireflective
filter on
the screen.
- Make
effort to
blink more
frequently.
- Use
an artificial
tear product
like tear
plus eye
drops 4 times
a day.
