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.

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.

SYMPTOMSSymptoms of eye strain include tired, itching and burning eyes.

Any activity that requires intense use of the eyes for a prolonged time

or under difficult conditions can cause eye strain. These include extended

periods of:

Reading

Writing

Computer work

Driving

SYMPTOMS

Exposure to bright light or straining to see in dim light can

also cause eye strain.

One of the most common causes of eye strain is staring for

long periods at digital devices such as:

Computer screens

Smart phones

Video games

Eye strain and fatigue

Blurred or fuzzy vision

Dizziness, upset stomach

Difficulty focusing on work

Headaches and migraine headaches

Dry, red, or irritated eyes

Increased myopia (near sightedness)

Color vision changes

Slow ability to refocus

Excessive tiredness

Neck strain, shoulder, and upper and lower back pain

Occasional double vision, or eye-coordination problems

The overall symptoms of eye strain are as follows:

CAUSES

Too close to computer

Too many hours at the computer

Blinking less

Poor posture

Poor lighting

Excessive glare

CONVENTIONAL TREATMENT

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.

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.

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.

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.
