00:00:01.066 --> 00:00:05.286 
>> Computer Vision Syndrome.

00:00:05.286 --> 00:00:07.576 
Computer vision syndrome,
or CVS,

00:00:07.576 --> 00:00:10.816 
is a group of vision
problems that many people have

00:00:10.816 --> 00:00:13.386 
after looking for long
periods of time at the screen

00:00:13.386 --> 00:00:17.506 
of a digital device, such
as a computer, tablet,

00:00:17.506 --> 00:00:19.066 
e-reader, or cell phone.

00:00:19.066 --> 00:00:22.266 
The main cause is the
fuzzy dots, or pixels,

00:00:22.346 --> 00:00:23.936 
on the digital screen.

00:00:23.936 --> 00:00:25.796 
They make your eyes
change focus often.

00:00:25.796 --> 00:00:28.676 
Symptoms of CVS.

00:00:28.676 --> 00:00:35.776 
The signs and symptoms of
CVS include: the inability

00:00:35.776 --> 00:00:39.626 
to keep the letters on a
digital screen in clear focus;

00:00:39.626 --> 00:00:43.076 
eyestrain; pain around
the eyes; headaches;

00:00:43.076 --> 00:00:47.676 
neck and shoulder pain;
blurred vision; fatigue;

00:00:47.856 --> 00:00:50.696 
double vision; or dry eyes.

00:00:51.506 --> 00:00:54.356 
Your eyes may also feel dry
and gritty during the day.

00:00:54.486 --> 00:00:58.806 
They may feel worse if
you wear contact lenses.

00:00:58.836 --> 00:01:00.116 
Causes of CVS.

00:01:00.566 --> 00:01:05.756 
Symptoms may be caused by
one or more of these factors:

00:01:06.066 --> 00:01:10.216 
poor lighting; improper viewing
distance from a digital screen;

00:01:10.216 --> 00:01:14.066 
poor seating posture; glare
from a digital screen;

00:01:14.836 --> 00:01:18.016 
uncorrected vision
issues; and aging.

00:01:20.236 --> 00:01:21.796 
Treatment of CVS.

00:01:23.876 --> 00:01:26.366 
Treatment starts with
having a complete eye exam.

00:01:27.066 --> 00:01:29.936 
This includes tests to
show how your eyes focus

00:01:30.096 --> 00:01:32.586 
and work together when
viewing a digital screen.

00:01:33.346 --> 00:01:35.736 
Computer eyeglasses may
be prescribed for you

00:01:35.736 --> 00:01:38.046 
to wear while working
at a computer.

00:01:38.686 --> 00:01:40.226 
They can adjust your focus

00:01:40.286 --> 00:01:42.526 
so that your eyes do not
have to work so hard.

00:01:42.806 --> 00:01:46.346 
They might also help to correct
vision problems, such as:

00:01:46.976 --> 00:01:51.486 
farsightedness; astigmatism;
or presbyopia,

00:01:51.706 --> 00:01:54.796 
which is the inability to
focus on objects nearby.

00:01:54.956 --> 00:01:58.666 
A prescription for computer
eyeglasses should include an

00:01:58.836 --> 00:02:03.006 
antireflection coating and
a light tint to reduce glare

00:02:03.086 --> 00:02:04.446 
from the digital screen.

00:02:04.946 --> 00:02:08.466 
Other treatment options may
include: adjusting room lighting

00:02:08.466 --> 00:02:11.966 
to reduce screen glare;
improving posture;

00:02:12.726 --> 00:02:15.476 
determining the proper
position of the computer screen

00:02:15.556 --> 00:02:19.746 
and desk materials; and
following the 20-20-20 rule.

00:02:19.746 --> 00:02:24.196 
For every 20 minutes of screen
time, take a break and focus

00:02:24.196 --> 00:02:29.866 
on an object 20 feet away
for at least 20 seconds.

00:02:30.126 --> 00:02:30.926 
Things to remember.

00:02:33.116 --> 00:02:35.386 
Take frequent breaks
to relax your eyes.

00:02:35.856 --> 00:02:37.526 
For every 20 minutes
of screen use,

00:02:38.076 --> 00:02:41.886 
look at an object 20 feet
away for at least 20 seconds.

00:02:42.196 --> 00:02:45.656 
Make an appointment for an eye
exam to assess your symptoms.

00:02:46.466 --> 00:02:50.906 
Talk with your eye healthcare
provider about CVS and the setup

00:02:50.906 --> 00:02:52.326 
of your computer workplace.

00:02:53.016 --> 00:02:56.746 
Adjust the setup so your
screen is about 25 inches,

00:02:56.916 --> 00:02:58.976 
or an arm's length,
away from you.

00:02:59.776 --> 00:03:02.636 
It's also best to look
slightly down at the screen.

00:03:03.626 --> 00:03:05.916 
Get an antiglare screen
for your computer.

00:03:06.586 --> 00:03:09.246 
It will decrease the light
reflected from the screen.

00:03:10.416 --> 00:03:11.546 
Blink more.

00:03:11.696 --> 00:03:13.886 
It helps keep the
surface of your eyes moist

00:03:14.036 --> 00:03:16.386 
and lessens the chance
of developing dry eye.

00:03:16.836 --> 00:03:19.876 
And wear your computer
glasses daily

00:03:20.356 --> 00:03:23.096 
as you would any other
safety equipment.

00:03:24.756 --> 00:03:27.826 
What we have learned.

00:03:27.896 --> 00:03:31.346 
CVS is a group of vision
problems that many people have

00:03:31.526 --> 00:03:34.936 
after looking for long periods
of time at a digital screen.

00:03:35.156 --> 00:03:37.396 
True or false?

00:03:37.396 --> 00:03:40.786 
The answer is "true".

00:03:40.866 --> 00:03:44.726 
You can have CVS symptoms
while using a computer,

00:03:45.056 --> 00:03:46.946 
tablet, or even a cell phone.

00:03:49.366 --> 00:03:52.646 
Pain in the neck and
shoulders is a symptom of CVS.

00:03:53.696 --> 00:03:54.786 
True or false?

00:03:55.006 --> 00:03:58.116 
The answer is "true".

00:03:59.066 --> 00:04:01.756 
Other symptoms include
headaches and blurred vision.

00:04:04.346 --> 00:04:07.216 
Taking frequent breaks
will help prevent CVS.

00:04:08.266 --> 00:04:09.206 
True or false?

00:04:11.116 --> 00:04:12.536 
The answer is "true".

00:04:13.836 --> 00:04:15.666 
Follow the 20-20-20 rule.

00:04:16.256 --> 00:04:19.276 
Take a 20-second break
every 20 minutes to look

00:04:19.276 --> 00:04:23.756 
at something 20 feet away.

00:04:24.256 --> 00:04:28.930
