3. COMPUTER VISION SYNDROME, more commonly known
as COMPUTER EYE STRAIN is a combination of vision problems
noticed during and after working long hours on the computer. It as a
repetitive strain disorder affecting 90% of human workers on
computers daily.
INTRODUCTION
Staring at your computer for long hours without a break strains
your eyes and bodies and results in computer eye strain.

4. In the case of students on computers and computer professionals, the
HEV light emitted by computers is another serious source of light that can
damage the retina and cause macular degeneration.
HEV ( HIGH-ENERGY VISIBLE ) Blue Light
Over time, too much computer use has negative effects that add up
including development of farsightedness (presbyopia), near sightedness
(myopia), astigmatism, poor eye-coordination, and ability-to-focus disorders. In
addition, sitting in the same position for hours causes neck, back and shoulder
stiffness and tension headaches, which in turn cause TMJ ( Temporo Mandibular
Joint) pain. And, of course, the threat of direct damage to the retina from HEV
blue light.

9. SELF HELP FOR COMPUTER EYE STRAIN
1. Swallow a pain reliever with water. This relieves the headache pain, but
will not prevent further problems if you do not adjust how you use the laptop.
2. Take a break away from the laptop. Mayo Clinic suggests a 20/20/20 rule
which means every 20 minutes focus your eyes on something at least 20 feet away
from you for at least 20 seconds.

10. 3. Go to an eye doctor to check your vision if you wear corrective lenses
and haven't been in for a check up in over a year.
4. Leave your computer area. Stretch your body by doing simple exercises
or lie down for a few minutes with your eyes closed. This not only helps to relieve
your headache, it refreshes your entire body.

11. 5. Position your laptop at least 20 inches away from your eyes. If you have
difficulty reading the screen, increase the font size on your computer by hitting the
"ctrl" button and the "+" sign at the same time. Decrease the font size by hitting
"ctrl" and the "-" button at the same time.
6. Turn the monitor off on your computer, but leave the screen up. If there is
a glare on the screen, this may be the cause of your headache. Reposition the laptop,
sit elsewhere or adjust window blinds, lights or curtains to remove the glare.

12. 8. Use artificial tears throughout the day if your eyes often feel dry. This
helps cut down on the eyestrain and reduces the chance of your getting another
headache.
7. Dust the laptop screen frequently. The dust on the screen reduces the
contrast on the laptop screen. It also contributes to reflection and glare problems.
